    A tool for boring cavity holes in concrete walls and the like comprises a cutting blade pivotally mounted about a transverse pin at the end of an elongate body and having a camming profiled portion. A ball is placed at the bottom of the hole which has first been bored with a conventional drill and the tool cutting blade is brought into contact with the ball while causing rapid rotation of the tool body and exerting an axial pressure. The ball cooperates with the blade camming profiled portion so as progressively to orient the blade in a transverse direction.

    The invention relates to medical technology and can be used for lower limb prosthetics with disabilities.
    The purpose of the invention is to provide reliable resilience by force locking the front stops of the prosthesis during a forward jerk.
    FIG. 1 shows the structural scheme of the hip prosthesis; in fig. 2 shows section A-A in FIG. one; in fig. 3 illustrates an exemplary embodiment of a multiplier transmission of a hip prosthesis in fig. 4 and 5 - the extreme positions of the prosthesis and crank tibia in relation to the thigh without a multiplier transmission.
    The hip prosthesis (Fig. 1) contains the receiving sleeve 1 of the thigh and the shin 2 with stops 3 fixed on them, as well as a multiplier gear 4, made, for example, in the form of a gear planetary gear of the type of James (Fig. 2). The single-motion knee joint 5 connecting the receiving sleeve 1 of the thigh and the shin 2 is coaxial with the high-speed link 6 on which the crank 7 is fixed. In turn, the crank is connected to the receiving sleeve of the thigh 1 or with the lower leg 2 by means of a spring 8 and two hinges 9 and 10.
    FIG. 3 shows a hip prosthesis with a multiplying gear consisting of two pairs of external gears 11 and 12, in which the receiving sleeve 1 of the hip is connected to the low-speed wheel 13, and the high-speed link 6 of the transfer is connected to the crank 7. The spring 8 is installed using hinges 9 and 10 on the crank
    7 and shin 2 prosthesis.
    If the angle of full flexion of the lower leg relative to the thigh is φ ·> ^, then the angle of rotation corresponding to this span of the crank 7 (Fig. 3) with the use of a multiplicating gear planetary gear of the type of James is
    Υ = φ2ΐ. (1 + ^ -),
    Ζ 3
    where Ζ, and 2h are the numbers of teeth of the large and small central gear wheels.
    At the same time, the moment developed by the spring
    8 through a gear, is defined as
    Λ) 2'Ι | '· = Ρ | ΙΡ · · 4.5 (1 “) - С 1 -),
    where is the rip. - the force of elastic deformation of the spring 8;
    4g ; - shoulder strength Rpr. relative to the knee joint 5 (Fig. 5).
    The hip prosthesis works as follows.
    When the disabled person is walking after placing the prosthetic foot on the supporting surface (Fig. I 4), the stops 3 of the lower leg and the thigh are closed and their rotation relative to each other becomes impossible. When transferring the body of a disabled person to a healthy leg, the lower leg is partially flexed in the hinge 5. During this time interval, the crank 7 passes the bottom dead center, and the spring 8 takes a position in which the force of elastic deformation of the spring, increased by multiplying gear, contributes to the separation of the foot of the lower leg from the prosthesis support surface and throws it up and back. This phase of movement of the lower extremities of the prosthesis coincides with the accelerated movement of the lower leg relative to the thigh. With further bending of the tibia in the phase of its slow motion accumulation, the kinematic energy of the masses of the lower extremities after the crank transition through the upper dead center is expended on cocking the spring 8. This also changes the direction of the moment Mgr. After stopping the tibia 2 to the position of maximum flexion (Fig. 5 ), the spring accelerates the shin in the opposite direction and then with the help of the auxiliary movement of the thigh stump clockwise at some angle shin 2, overcoming the maximum tension of the spring, again occupies a stable position relative to the thigh, as shown in FIG. 4, before the delivery of the foot on the bearing surface. When the collars of the stops 3, the rebound of the tibia is reversed due to the force closure of these elements, which ensures reliable support of the knee joint.
    The effectiveness of the technical solution is that before placing the foot on the supporting surface, as shown in FIG. 4 rebound of the tibia 2 back after the collision of the stops 3 of the thigh of the tibia is prevented by a moment on the crank equal to the product
