    Laparoscopic Purification Device for Laparoscopic Surgery
    The present invention relates to a laparoscopic purification device for laparoscopic surgery, more specifically, to remove the liquid or foreign substances, such as blood inhaled while inhaling the surgical site during laparoscopic surgery, while circulating the inhaled gas back to the abdominal cavity wound The present invention relates to a laparoscopic purification device for laparoscopic surgery that removes smoke generated when burning a site, minimizes the time required to inflate the abdominal cavity after inhalation, and reuses the gas injected into the abdominal cavity. .
    In general, laparoscopic surgery is performed by observing the surgical site of the abdominal cavity through a plurality of small holes in the abdomen of the patient, and is widely used in gallbladder resection, appendectomy, and general surgery.
    Laparoscopic surgery uses trocars to inflate the abdomen and inject gas into the abdominal cavity to inflate it to a constant pressure. At this time, the gas injected into the abdominal cavity is mainly carbon dioxide which has no risk of explosion.
    In such a state, the surgical instrument is inserted into the surgical site of the abdominal cavity through the trocar, and then burned while the surgical site is incised, at this time, by the smoke generated when burning the surgical site and the liquid such as blood flowing when the surgical site is opened. It will obstruct the view of the surgical site.
    Therefore, in order to remove the blood flowing to the surgical site, the surgical site is inhaled to remove the blood, and to remove the smoke generated in the abdominal cavity, the trocar is inserted into one hole of the abdomen, and the gas is completely removed from the abdominal cavity. The smoke is removed and the trocar is inserted into another hole in the abdomen, and then gas is injected into the abdominal cavity from the outside to expand the abdominal cavity to a constant pressure again.
    Therefore, blood and smoke are completely removed from the abdominal cavity as described above, and when expanded at a constant pressure, the abdominal cavity can be easily observed from the outside through an endoscope.
    However, conventionally, in order to remove liquid such as blood flowing when cutting the surgical site of the abdominal cavity, the surgical site is inhaled, so the gas in the abdominal cavity is exhausted when inhaled, and gas must be injected again into the abdominal cavity. In order to remove the smoke generated during burning, draw out the outside completely through the trocar that is inserted into one hole of the abdomen, and then inject gas into the abdominal cavity through the trocar that is inserted into the other hole of the abdomen to inflate it at a constant pressure. Therefore, it takes a lot of time to remove the smoke generated when burning the surgical site of the abdominal cavity and to expand the abdominal cavity again after inhalation of the gas, as well as the problem that the gas injected into the abdominal cavity cannot be reused.
    In addition, since it is impossible to control the pressure of the air injected into the abdominal cavity through the trocar, there is also a problem in that the expansion pressure of the abdominal cavity cannot be kept constant.
    Therefore, the present invention has been proposed to solve the above problems, an object of the present invention while removing the liquid or foreign substances such as inhaled blood while inhaling the surgical site during the abdominal surgery while circulating the inhaled gas back to the abdominal cavity Laparoscopic laparoscopic purifier that removes smoke generated when burning wounds of the abdominal cavity, minimizes the time required to inflate the abdominal cavity after inhalation of gas, and reuses the gas injected into the abdominal cavity To provide.
    Another object of the present invention to provide a laparoscopic purification device for laparoscopic surgery that can maintain the constant pressure of the abdominal cavity by adjusting the pressure of the air injected into the abdominal cavity through the trocar.
    In order to achieve the above object, the present invention is inserted into the abdominal cavity at regular intervals, the first and second trocar having a constant passage therein; A connecting pipe for connecting the first trocar and the second trocar to communicate with each other; Circulation pump connected to the connecting tube, the liquid and foreign matter and gas such as blood flowing through the surgical site of the abdominal cavity through the first trocar to circulate to the surgical site of the abdominal cavity through the second trocar Wow; It is installed between the first trocar and the circulation pump, and includes a storage tank for collecting the liquid, such as blood or water sucked from the surgical site of the abdominal cavity through the first trocar by the circulation pump.
    1 is a view schematically showing a laparoscopic purification device for laparoscopy according to a first embodiment of the present invention.
    Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
    1, the laparoscopic purification device for laparoscopic surgery according to the present invention is inserted into the abdominal cavity at regular intervals, the first and second trocar (1) (3) having a constant passage therein;
    A connecting tube 9 for connecting the control tube 5 of the first trocar 1 and the control tube 7 of the second trocar 3 to each other;
    Is connected on the connecting tube (9), through the first trocar (1), such as blood flowing in the surgical site of the abdominal cavity and the like sucks the foreign matter and gas into the connecting tube (9) to the second trocar (3) Circulating pump 11 for circulating to the surgical site of the abdominal cavity through;
    It is installed between the first trocar 1 and the circulation pump 11, and is connected from the surgical site of the abdominal cavity through a suction pipe 13 inserted into the first trocar 1 by the circulation pump 11. The gas sucked into the tube 9 may include a reservoir 15 for collecting the liquid such as blood or water while allowing the gas to be passed through as it is.
    Is connected to the connecting pipe (9) between the circulation pump 11 and the first trocar 1 or the circulation pump 11 and the second trocar 3, the suction by the circulation pump (11) Gas, such as carbon dioxide required to maintain the pressure of the abdominal cavity in the gas of the abdominal cavity may pass through and may include a filter 17 for removing smoke generated when burning the surgical site.
    The suction pipe 13 is integrally connected with the connection pipe 9 located between the first trocar 1 and the reservoir 15 by the second connection pipe 19.
