    Field of the Invention
    [0001] The present invention relates generally to support structures to support patients during surgical procedures and, more particularly, to orthopedic tables to support a patient during surgical procedures, such as a knee replacement or hip replacement. Background of the Invention
    [0002] Certain surgical procedures, such as knee replacements or hip replacements, require manipulation and reorientation of the leg from a patient's normal position during a surgical procedure. For example, during total hip arthroplasty ("THA") or replacement surgery, the femoral head of the femur bone is separated from the hip joint or acetabulum, and the femoral head is then removed from the femur. To facilitate this procedure, and the insertion of replacement parts, it is necessary to reorient the patient's leg, in order to position and orient the femur in a more convenient position for the surgeon and surgical team.
    [0003] The present invention provides a support for the femur to more quickly position and orient a patient's leg, more specifically, the patient's femur. Summary of the Invention
    [0004] According to the present invention, a femur support set is provided for use on a surgical table to support a patient's femur during a surgical procedure.
    [0005] According to another aspect of the present invention, a femur support set is provided attached to an operating table. The support set consists of a support plate, and an elongated reciprocally movable rod in a direction generally vertical with respect to the support plate. An elongated support is mounted to the rod. The elongated support is rotatable on a stem and has a plurality of openings, as formed therein. Each of the openings defines a mounting position. A femur hook is provided having an end sized to be received in one of the plurality of openings.

Detailed Description of the Preferred Embodiment
    [0033] Referring now to the drawings in which the presentations are for the purpose of illustrating a preferred configuration of the invention and not for the purpose of limiting it, FIG. 1 shows an orthopedic table 10 illustrating a preferred configuration of the present invention. In general terms, the orthopedic table 10 consists of a patient support 20, which is mounted on a support column 12 that extends upwards from a base 14. The patient support 20 is symmetrical about an axis center, designated "A" in the drawings, which extends along the length of the patient's support 20. The support column 12 and the base 14 are conventionally known and therefore are not shown, and will not be described in great detail . The support column 12 is typically a telescopic structure that allows the vertical adjustment of the patient support 20. The base 14 can be motorized, in order to allow the movement of the orthopedic table 10 along the floor 16 or can be fixed rigidly to the floor o 16 in a stationary position.
    [0034] In the configuration shown, the patient support 20 consists of a head / trunk support 22 and a sacral support 42. The head / trunk support 22 is generally constituted by a support frame 24 which has a generally planar top surface. An elastic pad or mattress 28 is arranged and / or attached to the support frame 24. In the configuration shown, the support frame 24 is a integrally formed member. In the configuration shown, side rails 32 are attached to the side walls of the support structure 24. The support frame, frame 24 and cushion / mattress 28 on it provide support for the patient's head and trunk.
    [0035] Sacral support 42 is positioned at one end of the head / trunk support 22. Sacral support 42 is comprised of a sacral plate, generally triangular, having a downwardly extending flange 44a formed at a first end thereof . The sacral plate 44 is symmetrical about the patient support axis A 20 and can be attached to the frame support 24 of the head / trunk support 22. Conventional fasteners 46 that extend through holes in the support 34 capture the flange 44a against the support structure 24, as best seen in FIG. 6. Two openings spaced apart 52, 54, best seen in fig. 6. are formed by means of the sacral plate 44 adjacent to its free end. The openings 52, 54 are aligned along the A support axis of the patient 20. A resilient sacral cushion or mattress 56 is arranged and connected to the sacrum plate 44. The sacral cushion 56 has a first end 56a that abuts the head / trunk support 22, and the second end 56b is formed to have a cylindrical notch 62 or recess formed therein. As illustrated in the drawings, sacral cushion 56 is shorter in length than that of sacral plate 44. A positioning pillar 72 is provided to be positioned on the free end of sacral plate 44. The positioning pillar 72 is basically constituted by a rigid, structural pin 74, having a resilient, 76 surrounding you and a main portion of the pin. The pin 74 has a lower end part 74a of reduced size extending from the pad 76. The lower end part 74a of the pin 74 is sized to be received within the openings 52, 54 formed at the end of the sacral plate 44. In a preferred configuration, pin 74 is formed of a carbon fiber compound. In the preferred configuration, the pin 74 is cylindrical in shape and a cylindrical tubular pad 76 surrounds the pin 74. A part of the base pad 82 is formed near the lower end of the cylindrical pad 76 and extends to one side thereof. When viewed from above along the axis of pin 74, base pad part 82 has a square shape, where base pad part 82 has parallel sides and rounded, cylindrical ends. The base pad part 82 of the positioning pillar 72 has a thickness that corresponds to the thickness of the sacral pad 56. The rounded cylindrical ends of part of the base pad 82 are sized to mate with the cylindrical cavity 62 formed in the pad sacral 56.
    [0036] As shown in the drawings, the lower end 74a of pin 74 extends from the padded portions of resilient pad 76 and the base part 82 such that part of the lower end 74a of pin 74 can be positioned on the openings 52, 54 formed in the sacral plate 44. In this respect, the openings 52, 54 in the sacral plate 44 are arranged in such a way that the positioning pillar 72 can be mounted on the sacral plate 44 in one of the two positions, as illustrated in the drawings. In one position (shown in FIG. 3), the positioning pillar 72 is arranged closer to the head / trunk support 22. In a second position (best seen in Fig. 5), the cylindrical pad 76 of the positioning pillar 72 is arranged in opening 54 and therefore meet even further from the head / torso support end 22. In both positions, the rounded, cylindrical ends of the base pad part 82 of the abutment mate closely with a cylindrical notch or recess 62 formed at the second free end of the sacral cushion, 56.
    [0037] As will be described in more detail below, pin 74 and pad 76 of positioning pillar 72 is provided to be placed between the legs of a patient to position the patient on the patient support 20. The dual configuration of the orifice of the Sacral plate 44 allows adjustment of the position of pin 74 and pad 76 in relation to the size of a patient, as will be described below.
    [0038] Referring now to FIGS. 7-10, a femur support assembly 112 will be best seen. The femur support assembly 112 includes a housing 114. Housing 114 includes 114A an upper and lower housing section 114B. The upper housing 114A is designed to condense on the lower housing section 114B, as will be described in more detail below. The support / guide structure 118, best seen in Figs. 9 and 10, is arranged inside the lower section of housing 114B. Support / guide structure 118 includes a bottom wall 118, and an upper wall 118b, and two spaced side walls 118c, 118d, which extend upwardly from the bottom wall 118. A mounting bracket 122 extends upwardly from the bottom wall 118a. On one side of the support, a tubular pillar 118e extends vertically up from the bottom wall 118 upwards 118b the housing wall 118. In the configuration shown, the tubular pillar 118e is cylindrical in shape.
    [0039] A block 126, extends from the side wall 118d of the guide support structure in the lower section of the housing 114B through the lower housing section 114B. In the configuration shown, block 126 has a rectangular cross section.
    [0040] A motorized lifting device 128 is arranged within a support / guide structure 118 in the lower housing section 114B. In the configuration shown, lifting device 128 is a linear actuator having a body part 128 and a part of a movable rod 128B extending from body part 128A. The stem part 128B can be operated to move along a linear path with respect to the body part 128A. The lower end lifting device 128 is attached to the support 122 which extends from the bottom wall 118 of the support / guide structure 118. The free end of the stem part 128 A extends through an opening 119 in the upper wall 118b of the support / guide structure 118 and is attached to a support 129 that extends downwardly from a horizontal support plate of plate 132. Support plate 132 includes an elongated joint 134 that extends vertically downward from the plate support 132. The joint 134 extends generally parallel to the stem part 128B of the lifting device 128. The joint 134 is dimensioned to be received inside the cylindrical opening defined by the tubular pillar 118E that is part of the support structure / guide 118 in the lower housing section r 114B. In this regard, in the configuration shown, the gasket 134 is cylindrical in shape and defines an elongated cylindrical opening, 135, which extends through gasket 134 and through support plate 132. In the configuration shown, gasket 134 is formed as an integral part of support plate 132. As will be described in greater detail below, tubular pillars 118e act as a guide for joint 134.
    [0041] The upper housing section 114A is dimensioned to be mounted on the support plate 132 by conventional fasteners 137. An upper part of the joint 134 is in alignment with an opening 142 through the upper part of the upper housing section 114, as best seen in Figures 9 and 10. The gasket 134 on the support plate 132 is dimensioned to receive an elongated rod 144, having a plurality of aligned cylindrical holes spaced the part 146 formed along one of its sides. The rod 144 is dimensioned to slide vertically inside the joint 134. In this sense, the rod 144 is movable in relation to the support plate 132 and upper housing section 114A. A biased spring locking pin having a button 152 at one of its ends is dimensioned to be received in one of a plurality of cylindrical holes 146 formed on the side of the elongated stem 144. As shown in FIGS. 9 and 10, the bias spring locking pin 148 extends across the support plate 132 of the stem 144 to lock the stem in one of several positions with respect to the support plate 132 and the upper housing section 114A.
    [0042] A part of the mounting pin 156, of reduced diameter is formed at the upper end of the rod 144 to define a support structure. An elongated support hook 162 is mounted on the part of the pin 156 on the upper end, free of the rod 144. As best seen in FIG. 9, a cylindrical hole 164 is formed at one end of the elongated support hook 162. The cylindrical hole 164 is sized to receive part of the pin 156 at the upper end of the rod 144. The part of the pin 156 includes an annular groove 158 that has a usually semicircular cross section. An oval point adjusting screw 166 extending to the end of the elongated hook support 162 communicates with annular groove 158 on the part of pin 156 to lock the hook support on the rod 144 and to allow the rotation of the hook support 162 on stem 144 in a horizontal plane perpendicular to the axis of the vertically oriented stem 144, as illustrated by the arrow in FIG. 7.
    The hook support 162 is an elongated structure having a plurality of overlapping openings 172 formed along the length thereof. Each aperture 172 may be formed in the form of a polygon or a star, or have a radiant configuration like a star arranged in a center. In the configuration shown, each opening 172 is in the form of a hexagon. Each opening 172 defines a mounting position for a femur hook 182.
    [0044] The femur hook 182, best seen in fig. 7, it is generally comprised of an elongated bar which is curved to have a J-shaped hook part of the hook 182a at a horizontal end of the intermediate leg part 182b and a part of the vertical leg 182c. The vertical leg portion 182c of the femur hook 182 has a pillar 184 formed at the lower end thereof. A hand 186 or handle is formed above the abutment 184 to facilitate the handling of the femur hook 182. The abutment 184 in the femur hook 182 is sized to be received inside the openings 172 formed in the hook support 162. In the configuration shown, pillar 184 has a hexagonal shape. As best illustrated in FIG. 8, the shape of the hexagonal openings 172 and the hexagonal shape of the pillar 184 on the hook of the femur 182 is made. The hook of the femur 182 can be positioned in one of six different positions, within each hexagonal opening 172 on the hook support 162. The hook support 162 and femur support 182 are preferably formed of metal, such as, for example and not limiting, stainless steel.
    [0045] Referring now to FIG. 7, a mounting assembly 210 for the femur mounting bracket assembly 112 the orthopedic table 10 will be best seen. In the configuration shown, the mounting set 210 is basically comprised of a tubular cross member 212 and an L-shaped support 222. The cross member 212 has a pair of spaced pins 214 extending from one side thereof . The Tubular Cross member 212 defines an internal opening 216 through it in a generally uniform transverse shape. Hand screws 218 are positioned at each end of the cross member 212 and extended at the opening 216. The pins 214 are sized to be received in the cavities formed inside the support structure 24 of the orthopedic table 10. Hand screws 220, best seen in fig. 8, extend through the threaded openings in the cavities being adapted to engage the pins 214 on the cross member 212 to lock the cross member 212 in a horizontal position relative to the frame support 24 of the orthopedic table 10. Each end of the cross member 212 is dimensioned to receive a leg 222a of the L-shaped support member 222. In the configuration shown, both the tubular cross-member 212 and the L-shaped support 222 have rectangular cross sections and are respectively sized so that the first leg 222a of the L-shaped support 222 can be received within one end of the internal opening 216 defined by the tubular cross member 212 and moving telescopically therein. The hand screw 218 associated with one end is used to secure the L-shaped support 222 on the cross member 212. The L-shaped support 222 is arranged within the tubular cross-member 212 so that a second leg 222b of the support 222 extends vertically downwards with respect to the surface of the patient support 20 of the orthopedic table 10. The lower end of the second leg 222b of the L-shaped support 222 has a rectangular transverse opening 224 extended therebetween. The opening 224 is sized to receive the rectangular block 126 which extends from the lower housing section 114B of the femur support assembly 112, as shown in FIG. 7. A hand screw 226 that is aligned to extend axially along the length of the second leg 222b of the L-shaped bracket 222 secures the femur support assembly 112 by locking the rectangular block 126 to the second leg 222b of the support L-shaped 222.
    [0046] According to one aspect of the present invention, the first leg part 222a of the L-shaped support 222 can be inserted at the end of the tubular cross member 212. In addition, the rectangular lock 126 in the support set of the femur 112 can be inserted through the end of the opening 224 through the second part of the leg 222b of the L-shaped support 222. In this sense, the femur support set 112 can be used on the side of the orthopedic table 10, as will be described in more detail below .
    [0047] Referring now to FIGS. 1 and 2, two leg supports side-by-side 312A, 312B extend from the support structure 24 of the orthopedic table 10. The leg support 312A is attached to the support structure 24 below the sacral support 42 and is generally rotated on an axis vertical. In the configuration shown, the leg support 312A is comprised of a proximal section 314 and an elongated stringer section 316. One end of the proximal section 314 is connected to the support structure of the table 24 to be pivoted on the above-mentioned vertical axis. The other end of the proximal section 314 is connected to one end of the elongated stringer section 316 by a joint set 322. The joint set 322 allows the elongated stringer section 316 to rotate about a vertical axis relative to the proximal section 314 and to be fixedly secured at the selected angular positions relative to the vertical axis. More specifically, the gasket set 322 allows the elongate spar section 316 to rotate about a vertical axis that is generally parallel to the vertical axis connecting the first end of the proximal section 314 to the table support structure 24. The gasket set 322 includes an adjustable rotary locking and unlocking device of the type described in U.S. Patent No. 5,689,999 Wiley et al., dated November 25, 1997, the disclosure of which is expressly incorporated herein by reference.
    [0048] The gasket set 322 further includes a cylinder having one end fixed to the gasket set 322 and the other end fixed to the elongated stringer section 316. The cylinder 326 allows the elongated stringer section 316 to swing down and up, that is, declining and tilting, in relation to the axis of the proximal section 314 and to be blocked with a declining angle, or the inclination angle in relation to the proximal section 314 of the leg support. In other words, the elongated stringer section 316 can generally be swung downwards or upwards, through a plane generally parallel to the plane defined by the patient support 20. Once swung downwards or upwards, at a specific angle, the elongated section 316 may oscillate above the junction axis between the proximal section 314 and the elongated stringer section 316 and be locked in a number of positions relative to the vertical axis connecting the elongated stringer section 316 to the proximal section 314. The free end of the section elongated stringer 316 includes a handle 328 and a release lever 332 that controls the release of cylinder lock 326 to control the position of the elongated stringer section 316.
    [0049] Referring now to FIG. 11, a drive set of 400 and a mounting frame 340 to secure the drive set of 400 to the elongated stringer section 316 are best seen. The mounting structure 340 consists of a release clamp 342 attached to the stringer section 316 of the support leg 312, a support arm 352 mounted to secure 342, and a support hub 362 attached to the support arm 352.
    [0050] Releasable clamp 342 is provided to secure the elongated stringer section 316. Clamp 342 is essentially a C-shaped collar that has a first collar adjustment screw 344 (best seen in FIG. 1 and 2) extended through clamp 342 to lock clamp 342 in elongated stringer section 312. The first collar adjustment screw 344 includes a handle and allows the release of clamp 342 in elongated stringer section 316 to be released at different positions along its length . The clamp 342 includes a mounting projection 346 (best seen in fig. 11) that has an opening extended therebetween. The opening is dimensioned to receive a support arm leg generally L-shaped 352. Support arm 352 has a first leg 352a and a second leg 352b. A second collar adjustment screw 348 having a button on it is provided to allow the leg 352a of the support arm 352 to be locked in place relative to the clamp 342 in different positions along the leg 352a of the support arm 352. Leg 352b of the arm holder 352 includes a holder assembly 360 at its end. Support assembly 360 is comprised of a support hub 362 and a support assembly 372. Support hub 362 is generally cylindrical in shape and includes a tapered bore 364 (best seen in Fig. 13) formed at one end thereof. The support hub 362 and the tapered bore 364 are symmetrical above a central axis. The hub 362 is attached to the support arm 352 in such a way that the axis of the support hub 362 is generally oriented vertically.

The rotation of the manual button 396 in a first direction above the longitudinal axis of the threaded shaft 398 causes jaw 392 to move towards channel 382. Rotation of the manual button 396 in the opposite direction on the longitudinal axis of the threaded axis 398 motivates the jaw 392 to move away from channel 382.
    [0053] The inner face of the side wall 378 and the inner face of the jaw 392 are recessed to define the recessed parts 379, 393, respectively, wherein the channel 382 defined by the jaw 392 and the side wall 378 having generally tail shapes swallow in the cross section. A plurality of axially aligned positioning pins 397 extend upwards from the bottom surface of channel 382. The positioning pins are aligned along the length of channel 382.
    [0054] The tapered portion 376 of the support assembly 372 is sized to have a tapered outer surface 376a according to tapered bore 364 in the support hub 362. As best seen in FIG. 13, the threaded shaft 370 on the locking wheel 366 is dimensioned to extend into a threaded opening 377 formed at the bottom of the tapered part 376. Rotation of the locking wheel 366 in one direction is operated to extract the tapered part 376 in mounting the support 372 below the tapered bore 364 and in engagement with the support hub 362 to block the mounting of the support 372 to the support hub 362. In this sense, the mounting of the support 372 is locked at an angular position above the axis of the support hub 362.
    [0055] As described above, the mounting of the support 372 is dimensioned to receive the traction set 400 in it. Traction assembly 400 is comprised of a sliding assembly 410 and the traction device 600. The sliding assembly 410 basically consists of a rectangular base 420 and an elongated traction support 520 that is operable to reciprocally slide along the base 420. Base 420, best seen in FIG. 15, consists of a generally rectangular housing 422 with an elongated opening 424 formed through its upper surface. A pair of flanges 422a, 422b is formed on the upper surface of the housing 422 and on the opposite sides of the opening 424. The housing 422 is preferably formed of extruded metal. A U-shaped block 426 and two spaced plates 432, 434 are disposed within the housing 422. The U-shaped block 426 defines an elongated groove 428 therein. The groove 428 is aligned and in the register with opening 424 in the housing 422. The plates 432, 434 define the opposite flat faces 432a, 434a, respectively. The spaced plates 432, 434 are harmonized so that the flat faces 432a, 434a define a slot 436 of generally rectangular cross section between them.

O adjustment screw 442 is similar to the adjustment and locking devices 394 described above. In this regard, the adjusting screw 442 is basically composed of two guide handles 444, spaced apart having a threaded shaft 446, extended between them. The threaded shaft 446 is sized to be received within the threaded openings formed in the plates 432, 434. Rotating the threaded shaft 446 in a direction above its axis causes the plates 432, 434 to move towards each other, to reduce the width of the slot 436 defined therein. Rotation of the threaded shaft 446 in the opposite direction increases the dimension of the slot 436.
    [0057] An elongated toothed plate 452 is attached to flange 422B of housing 422 by conventional fasteners 454. Plate 452 extends parallel to opening 424 in housing 422 and a groove 428 in block 426. Plate 452 has a plurality of teeth 456 evenly spaced, extended over it.

A channel 526 is formed along the length of the traction support 520, adjacent to the side wall 524 Two spaced wall sections 532, 534 are formed along the opposite edge of the traction support base part 522 520. The wall sections 532, 534 define an opening 536 that communicates with channel 526. A movable jaw 538 is dimensioned to be arranged in the opening 536 defined by the wall sections 532, 534. The jaw 538 is movable in relation to the opposite side wall 524. Manually operable adjustment devices 542, similar to the adjustment device 394 described above with respect to mounting support 372, being operated to move jaw 538 in the opposite direction and out of the side wall 524. Adjustment devices 542 are composed of a manual button 544, similar to those described above, having a threaded shaft 546 that extends from it. Each threaded shaft 546 is dimensioned to be screwed into a housing, the threaded opening on the sides at the base part of 522. As described above, the rotation of knob 544 in one of the two directions causes jaw 538 to move in either direction or outside the opposite side wall 524.
    [0060] As indicated above, the channel 526 is formed between the side wall 524, on one side of the base part 522 and the jaw 538 on the other side of the base part 522. The inner face of the sidewall 524 and the inner face jaws 538 are recessed to define notched regions. Together, the side wall 524 and the jaw 538 define a dovetail channel 526 along the length of the traction support 520. According to one aspect of the present invention, the dimensions and shape of the channel cross section 526 defined along the traction support 520 is identical to the dimensions and forms the cross section of the channel 382 defined in the assembly of the support 372. In this context, the jaw 538 in the traction support 520 has a cross-sectional shape similar to that of the jaw 392 in the assembly of the support 372, with the exception that the jaw 538 is larger and includes two adjustment devices 542.
    [0061] The traction support 520 is formed to have a cup-shaped cavity 552 disposed at one end thereof. Cavity 552 is placed on the upper surface of the traction support 520 and communicates with channel 526 extending along the upper surface of the traction support 520. Cavity 552 is dimensioned to accommodate part of the traction device 600, and must be described in more detail below. Fixing pins 554 are arranged inside the channel 526 and extend above the surface of the base channel 522. The fixing pins 554 are aligned along the length of the channel 526.
    [0062] The traction support 520 also includes a lower rail 556, best seen in fig.13, which extends along the length and bottom of the same. Lower rail 556 extends along the length of the traction support 520 and is generally rectangular in cross section, and being dimensioned to be received in the groove 428 of the base 420. Lower rail 556 is operable to be received inside the groove 428 and to be reciprocally movable through it when the adjusting screw 442 on the base 420 is positioned to define an interval between the sides of the rail 556 and opposite faces 432a, 434a of the plates 432, 434 within the base 420. The rail 556 is operated to be locked in a specific position in relation to the base of 420 by means of adjustment screw 442 described above. In this regard, the traction support 520 can be fixed with respect to the base of 420 by adjusting the adjusting screw 442 to cause the plates 432, 434 to collide against the sides of the lower rail 556.
    [0063] A channel 562, best seen in fig. 13, is formed on the underside of the traction support 520 to one side of the lower rail 556. Channel 562 extends along the length of the traction support 520 parallel to the rail 556. An elongated rack 566, best seen in fig. 15 and in the cross section in fig. 13, having downward facing teeth 568 sized to engage with teeth 456 in plate 452 on base 420, being mounted inside channel 562. Rack 566 is mounted to be reciprocally movable between a lower first position, where rack 566 engages and engages with plate 452 on base 420, and a second, retracted position, in which rack 566 is spaced from plate 452. Rack 566 is connected to a mechanical connection (not shown), which in turn instead it is connected to an axis 572 extended through the base part 522 of the traction support 520. The rotation of the axis 572 controls the movement of the rack 566 between the first, lower position and the second retracted position. The shaft 572 is disposed near one end of the traction support 520. The levers 574 are provided at each end of the shaft 572 to allow a member of the surgical team to control the movement of the rack 566. The rack 566 on the traction support of 520 and the plate 452 on the base 420 provide a second mechanism for locking or unlocking the traction support 520 to the base 420 and providing a means of control, i.e. lever 574, near the operational end of the traction support 520.
    [0064] Referring now to FIG. 11, traction device 600 will be better seen. Traction device 600 is generally cylindrical in shape and has an outer tubular body 612 having an enlarged cup-shaped first end 614. A set of elongated shafts 622 is dimensioned to extend through tubular body 612 and to have a projection part 624 , which extends or projects from a second end 616 of the tubular body 612. The shaft assembly 622 includes a linear screw mechanism (not shown) disposed within the tubular body 612 that allows the length of the shaft assembly 622 to increase or decrease along an X axis of the axis assembly 622 based on the rotation of a first end of the axis assembly 622. In the configuration shown, the length of the projection part 624 of the axis assembly 622 increases or decreases based on the rotation of the axis. first end of shaft assembly 622. A cover 632 having a handle 634 is attached to the first end of shaft assembly 622. Using handle 634, cover 632 and the first The end of the shaft assembly 622 can be rotated in both directions as illustrated by the arrows in fig. 11. In this sense, turning the crank 634 in one direction motivates a set of axes 622 to condense on the tubular body 612 of the traction device 600. Rotating the crank 634 in the opposite direction motivates the set of axles 622 of the traction device 600 if move externally in precise, small increments of tubular body 612 of traction device 600.
    [0065] A generally cylindrical collar 636 is disposed between the cap 632 and the first enlarged cup-shaped end 614 of the tubular body 612. The collar 636 is dimensioned in such a way that the outer surface of the collar 636 is an extension of the surface of the first cup-shaped end 614 of tubular body 612. Collar 636 includes a handle 642 generally oriented perpendicular to the X axis of the pull device 600. A release button 644 is provided at the free end of handle 642. The release button 644 is connected to a locking mechanism (not shown) inside the tubular body 612, which locks the shaft assembly 622 to the tubular body 612, in order to prevent the angular rotation of the shaft assembly 622 on the X axis. release button 644 releases the locking mechanism and allows the set of axes 622 to rotate angularly about the X axis. As best seen in FIG. 11, a scale 638 is provided along the extreme surface of the first enlarged cup-shaped end 614 of the tubular body 612. A marker indicator 646 on the collar 636 is arranged opposite the scale 638 to provide an indication of the amount of angular rotation of the assembly from axis 622. Releasing release button 644 on grip handle 642 will lock axis assembly 622 into position of axis assembly 622 when release button 644 is released.
    [0066] A cap support 660 is attached to the free end of the shaft assembly 622. As will be described in more detail below, cap support 660 to attach to a cap (not shown) on a patient's foot during a surgical procedure . Cover holder 660 basically consists of a flat plate 662 attached to a mounting assembly 664 at the free end of the shaft assembly 622. Plate 662 is operated to move with the shaft assembly 622 linearly along the X axis or rotationally about the X axis. In the configuration shown, a handrail 666 is provided on the rear side of plate 662, closest to the traction device 600.
    [0067] An elongated plate 672 extended along the lower side of the tubular body 612, as best seen in FIG. 17. Plate 672 is attached to a tubular body 612 by conventional fasteners (not shown). A plurality of spaced openings 674 are aligned along plate 672. Openings 674 are sized and spaced to allow pull device 600 to be mounted on pins 554, in different positions along pull pull 520. In addition, the openings 674 are dimensioned and spaced to allow the traction device 600 to be mounted on pins 397 of the support assembly 372. The side or side edges 672a of the plate 672 are recessed and angled internally, to be received in the notched regions 382, 526 in the assembly of support 372 and traction support 520. Once traction device 600 is fixed in place in a desired position along traction support 520, traction device 600 can be locked in place by adjusting the position of the jaw 538 internal to capture the plate 672. In a similar way, traction device 600 can be mounted on the mounting of the support 372, by adjusting the position of the jaw 392.
    [0068] Referring now to the operation of the orthopedic table 10, the orthopedic table 10 is designed primarily for surgical procedures involving the patient's legs and, more specifically, for surgical procedures, such as knee replacement, bone pins of the leg, or total hip replacement.
    [0069] Before any of the aforementioned surgical procedures, the patient is positioned, face up, on the patient's support 20. The patient's head and trunk are supported by the head / trunk support 22. The hips of the patient are supported by the sacral support 42 with the patient's groin positioned vertically, by the positioning pillar 72 with the sacral support 42. According to one aspect of the present invention, depending on the height, that is, the length, of the patient, the pillar positioning device 72 can be positioned in one of two positions on the sacral plate 44, as illustrated in FIGS. 3 and 5.
    [0070] With the patient lying on the patient support 20 with the patient's legs positioned on the leg supports 312a, 312b, each of the patient's feet is fastened within covers (not shown) that are attached to the plate 662 on the support cover 660 of the traction device 600. If necessary, the position of the traction device 600 in relation to the patient can be adjusted in several ways. For example, clamp 342 can be repositioned along the elongated stringer section 316 using the first collar adjustment screw 344. Support arm 352 can be adjusted relative to clamp 342 through the second adjustment screw of the collar. collar 348. Similarly, the angular position of the support assembly 372 relative to the axis of the support hub 362 can be modified using the locking wheel 366. In addition, the traction support 520 that has traction device 600 on it can be moved relative to the base 420 using the adjustment screw 442 on the base 420 or handles 574 on the traction support 520. In this respect, loosening the adjustment screw on the base and / or disengaging the rack in the plate support on the base, allows the support freely slide in relation to the base.
    [0071] During hip replacement surgery, an incision is made in the patient's hip. The leg muscles are then separated to allow access to the hip. The head of the femur is then cut from the femur, while the head is still at the hip joint. The head of the femur is then removed from the hip joint. Once the femur is separated from the hip, the cartilage at the hip joint and the acetabulum is then removed by the surgeon. An acetabular implant or cup component is then inserted into the surgically modified hip, usually by cement, special screws or mesh that accepts bone growth to firmly fix the cup to the pelvis.
    [0072] At a certain stage of the process, the femur hook 182, which at this point is separated from the femur support set 112, is inserted into the patient's leg to capture the patient's femur bone. The end of the femur is removed from the patient's leg using the femur hook 182. The femur hook 182 with the respective femur is then mounted from the support hook 162 through the insertion pillar 184, at the lower end of the femur hook 182 to a the plurality of openings 172 in the hook holder 162. As illustrated in FIGS. 7 and 8, the femur hook 182 can be oriented in any of several positions of a specific opening 172 in the hook holder 162. As indicated above, the hook holder 162 includes a plurality of aligned openings 172, each defining a location where the femur hook 182 can be inserted. Thus, the doctor can choose the most convenient location and one of the different angular positions at that location. The hook support capacity 162 to rotate on the part of the pin 156, as illustrated in FIG. 7, facilitates the positioning of the femur hook 182 in a suitable opening 172 in the hook support 162.
    [0073] During the procedure, the height, that is, the elevation, of the femur bone can be adjusted using the femur support set 112. In this sense, a rough adjustment can be made to the height of the femur hook 182 in the support of the hook 162 using a spring locking pin 148 and holes 146 in the elongated stem 144. In this sense, the physician may choose one of several elevated positions merely by removing the spring locking pin 148 from its locking position in relation to the rod 144 and raised rod 144 to a desired position and re-insert locking pin 148. In addition, vertical adjustments of hook support 162 and femur hook 182 can be made by initiating the motorized lifting device 128 in one direction or another to provide fine adjustment of the height of the femur end.
    [0074] The elongated stringer section 316 of the leg support 312a is released to allow the elongated stringer section 316 to rotate downward from a horizontal position to a declined position. Before rotating the stringer section 316 downward, the adjustment screw 442 on the base 420 of the slide assembly 410 is "released" to release the traction bracket 520 to move freely in relation to the base 420. In this sense, with the patient's foot attached to plate 662 on the traction device 600, when the elongated stringer section 316 is folded down, the traction device 600 being allowed to move the patient's foot when the stringer section 316 moves downward. Typically, if the patient's foot and leg are fixed, as the side member 316 rotates downwards, the traction device 600 and the traction support 520 will move relative to the base 420. In this sense, if the traction device 600 is locked relative to the base 420, the patient's leg will basically be extended when the elongated stringer section 316 is rotated downwards. By providing the sliding assembly 410 which allows the traction support 520 to slide in relation to the base of 420, the elongated stringer section 316 will be able to freely rotate downwards without placing undue strain or strain on the patient's leg.
    [0075] Once the elongated stringer section 316 is in a desired declined position, the traction support 520 holding the traction device 600 can be locked with respect to the base 420 by using the adjustment screw 442. The traction device 600 it is basically locked in position relative to the elongated stringer section 316 of the leg support 312a. In addition, less axial adjustment of the leg along the elongated stringer section 316 can be done using the handle 634 on the pull device 600. The handle 634 basically allows the leg to be stretched or bent in small increments along an axis which is essentially parallel to the 316 elongated stringer section.
    [0076] With the femur removed from the patient's hip, the patient's leg can also be rotated to one side or the other around the X axis of the traction device 600 using the grip handle 642 on the traction device 600. In this sense , by depressing the release button 644 on the grip handle 642, the locking mechanism (not shown) within the pull device 600 allows the axle assembly 622 (and the foot support 660) to be rotated angularly side-by -related to the X axis. In other words, a patient's foot, and therefore his entire leg, can be rotated laterally along the X axis of the traction device 600. (Because the head is not attached to the hip joint, the leg can easily rotate around the X axis of the traction device 600).
    [0077] With the femur supported on the femur hook 182 in a desired position and elevation, the traction device 600 can be used to make small longitudinal adjustments in relation to the position of the femur. Once in a desired position, the surgeon can proceed with the surgery by widening the femoral canal and attaching a metal ball to the stem to act as a point of hip articulation within the cup.
    [0078] After the completion of the necessary surgical steps, the traction support 520 of the sliding assembly 410 is released from the base 420, by reversing the rotation of the adjustment screws 442. The elongated stringer section 316 is then rotated back to a relative position to the patient's trunk. The patient's femur can then be rotated back to its normal position in relation to the patient's hip using the 642 grip handle and release the 644 button on it. In this sense, a graduated scale 638 on the collar 636 of the traction device 600 can be used to ensure that the femur will return to its original position in relation to the patient's repaired hip joint.
    [0079] The ability to quickly replace the patient's leg during the decline and inclination of the 316 elongated stringer section during the procedure significantly reduces the time of the surgical procedure. In this sense, the sliding assembly 410, when in a released configuration, allows the traction device 600 to slide reciprocally, with respect to the base 420 and in relation to the elongated stringer section 316 during its vertical movement. Once in a desired position, traction support 520 and base 420 of the sliding assembly 410 can be locked together and fine adjustments can be made by crank 634 on the traction device 600.
    [0080] While the slide set 410 is particularly useful and applicable with regard to total hip arthroplasty (THA), as a structure that cannot be required in conventional knee surgery or a surgical procedure for applying pins for certain leg bones. In these procedures, longitudinal stretching or contraction of the leg may be required. According to the present invention, the sliding assembly 410 discussed above, specifically, the traction support 520 and the base 420, can be removed from the orthopedic table 10 and the traction device 600 can be mounted directly on the mounting of the support 372, as illustrated in FIG. 18. In this sense, if the leg typically remains in a horizontal orientation during knee surgery, rough adjustment of the cover support assembly will not be required. Thus, for orthopedic tables that are not used for total hip replacement, the traction device 600 is mounted directly to the mounting bracket 372 in the elongated stringer section 316.
    [0081] The above description is a specific configuration of the present invention. It should be appreciated that this configuration is described for purposes of illustration only, and that numerous changes and modifications can be practiced by those skilled in the art without departing from the spirit and scope of the invention. It will be intended that all such modifications and changes will be included to the extent that they are within the scope of the invention as claimed, or their equivalents.
