The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.
As shown in fig. 1 and 2, the utility model provides a laparoscopic surgery auxiliary device, including hollow sleeve pipe 1, it is concrete, this sleeve pipe 1 is cylindrical structure, in this embodiment, this sleeve pipe 1 is the plastic tubing, directly adopt plastic material injection moulding can, processing is convenient to this plastic material is the plastics of medical grade.
More specifically, the outer side walls of two ends of the sleeve 1 are respectively provided with an annular air bag 2, and the sleeve 1 is provided with an air charging and discharging system respectively communicated with the two air bags 2; one end of the cannula 1 is detachably provided with a handheld part, and an air sealing component for surgical instruments to pass through is arranged in the inner cavity of the cannula 1.
The use principle of the auxiliary device is as follows:
when a laparoscope is used for gastric tumor resection in a gastric cavity, firstly, a puncture outfit is used for puncturing and opening a hole in the abdomen, the tip end of the puncture outfit penetrates through the abdominal wall until the stomach wall is punctured and enters the stomach, the auxiliary device in the novel device is conveyed to the stomach through the operation sleeve of the puncture outfit, specifically, a doctor holds the handheld part, the sleeve 1 is slowly placed into the operation sleeve of the puncture outfit until the air bag 2 at one end of the sleeve 1 penetrates through the gastric wall from the outside to the inside, then the air bag 2 at one end, far away from the handheld part, of the sleeve 1 is inflated through the inflation and deflation system, the puncture outfit is slowly pulled out for a certain distance in the inflation process, after the corresponding air bag 2 is inflated to a set range, the inflated air bag abuts against the inner side wall of the gastric wall, and then the positioning of the stomach can be realized through the handheld part; then the whole puncture outfit is slowly pulled out, the hand-held part is pulled tightly after the puncture outfit is pulled out, so that one air bag 2 close to the hand-held part on the sleeve 1 is exposed outside the abdominal wall, then the air bag 2 close to the hand-held part is continuously inflated through the inflation and deflation system to enable the air bag to expand and position and lean against the outside of the abdominal wall, so that the positioning of the stomach and the abdominal wall is realized through the sleeve 1 and the two air bags 2, and finally the hand-held part at the end part of the sleeve 1 is detached, and the inner cavity of the sleeve 1 forms an instrument operation space for performing stomach operations. Similarly, after the operation is completed, the hand-held portion is first put back on the sleeve 1, the air in the two air bags 2 is exhausted, the sleeve 2 is pulled out, and then the stomach wall and the abdominal cavity wall are sutured in turn by a special suturing instrument.
In addition, in the structure, because a certain amount of gas is required to pass through the stomach to enable the stomach cavity to be in an inflated state when stomach operation is performed, the stomach wall can be fully exposed, doctors can more clearly find focuses and perform corresponding operations, in order to ensure that the gas in the stomach does not leak, an air sealing assembly is arranged in the inner cavity of the sleeve 1, and in the structure, the surgical instruments can pass through the air sealing assembly while air sealing is performed.
The air sealing assembly comprises a mounting boss 3 and a movable valve 4, wherein the movable valve 4 is a substantially whole membrane, a plurality of partition grooves are radially formed along the center towards the periphery to form a plurality of flap-shaped diaphragms, a channel for instruments to pass through is formed between the flap-shaped diaphragms, and the flap 4 is tightly attached to the side wall of the instrument when the surgical instrument is inserted, so that air leakage is effectively prevented. Specifically, in the structure, the mounting boss 3 is integrally formed on the side wall of the inner cavity of the sleeve 1, and the circumferential outer edge of the valve membrane 4 is connected to the mounting boss 3.
In this structure, specifically, in this embodiment, the side wall of the sleeve 1 is provided with airflow channels 1.1 respectively communicating with the two airbags 2 along the axial direction, the outer ends of the airflow channels 1.1 are respectively inserted with the inflation and deflation pipelines 5, and the other ends of the inflation and deflation pipelines 5 are communicated with the external air supply mechanism.
