Problems solved by technology

[0002] In clinical surgery, when performing laparoscopic surgery, it is necessary to inject carbon dioxide into the abdominal cavity to form a pneumoperitoneum to establish a surgical operation space. At present, the instruments that can enter the pneumoperitoneum to complete laparoscopic gastrointestinal anastomosis are mainly laparoscopic straight line Type cutting stapler, this linear cutting stapler can only complete side-to-side anastomosis, can not complete end-to-sid

Abstract

The invention relates to an incision sealing device for a laparoscopic surgery. The device comprises a central master tube, a fixed plate, a sliding plate, telescopic tubes and a plurality of sub-tubes, wherein a piston is arranged in an interlayer cavity of the central master tube; one end of each sub-tube extends into the interlayer cavity of the central master tube to be communicated with the interlayer cavity; the sub-tubes are uniformly scattered along the circumferential direction of the central master tube; the telescopic tubes are arranged in the sub-tubes in a sleeving way; a piston is connected to the end, positioned in the corresponding sub-tube, of each telescopic tube; the fixed plate is arranged on the central master tube in the sleeving way; the sliding plate is arranged on a tube body of the central master tube between the fixed plate and the sub-tubes in the sleeving way. The incision sealing device can be accurately regulated according to the size of an incision, and airbags are arranged at contact parts of the sealing device and skin, and are freely deformed along with a change in a contact surface after being inflated, so that close contact and high sealing performance can be ensured all the time.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to an incision sealing device for laparoscopic surgery. Background technique [0002] In clinical surgery, when performing laparoscopic surgery, it is necessary to inject carbon dioxide into the abdominal cavity to form a pneumoperitoneum to establish a surgical operation space. At present, the instruments that can enter the pneumoperitoneum to complete laparoscopic gastrointestinal anastomosis are mainly laparoscopic straight line Type cutting stapler, this linear cutting stapler can only complete side-to-side anastomosis, can not complete end-to-side anastomosis, resulting in the tubular stapler most commonly used in laparotomy can not be used under pneumoperitoneum conditions, laparoscopic gastric ten End-to-side duodenal anastomosis, gastroesophageal end-to-side anastomosis, and esophagus-jejunum end-to-side anastomosis cannot be completed, and the side-to-side anast...
