Embodiment 1

[0027] Embodiment 1: A laparoscopic surgery pneumoperitoneum sealing device (see attached figure 1 ), including the top operating panel 2 with 5 sealed operating holes (see attached image 3 ), the sleeve 4 at the bottom with suitable elasticity and matching with the incision of the abdominal wall of the human body (see attached figure 2 ) and the flexible connection part 3 connecting the operation panel and the sleeve, the lower part of the operation panel is tapered, and the tapered surface is sleeved on one end of the flexible connection part and fixed. The operation panel is provided with a three-way switch 1 for the air intake hole, and the three-way switch for the air intake hole is connected to the insufflation tube. The five operation holes are divided into two 5mm operation holes 10, two 12mm operation holes 9 and one 27mm operation hole 13, Two 5mm operation holes are arranged adjacent to one side of the operation panel, and the three-way switch of the air intake h...

Embodiment 2

[0033] Embodiment 2: A laparoscopic surgery pneumoperitoneum sealing device (see attached figure 1 ), the operating panel of the closing device (see attached Figure 5 ) are provided with four operating holes, which are two 5mm operating holes 10 and two 12mm operating holes 9 respectively. The 5mm operating holes are symmetrical to each other, and the 12mm operating holes are symmetrical to each other. The two symmetrical lines are the same line. An air inlet three-way switch 1 is arranged on the top. Refer to Example 1 for all the other structures.

Abstract

The invention relates to a pneumoperitoneum closing device which performs gastrointestinal and gastroesophageal end-to-side anastomosis under a total laparoscope by using a tubular anastomat in a laparoscopic gastrointestinal operation. By the pneumoperitoneum closing device, the defects that the tubular anastomat used in the laparoscopic gastric cancer operation in the prior art is inconvenient to operate and air leakage is easily caused are overcome. The pneumoperitoneum closing device comprises an operating panel which is arranged on the top and is provided with a plurality of sealed operating holes, a sleeve which is arranged at the bottom, has appropriate elasticity and is matched with an incision of an abdominal wall of a human body and a flexible connection part which is connected with the operating panel and the sleeve, wherein the end part of the sleeve is provided with a blocking part, and the other end of the sleeve is provided with a turnover clamping part; the sleeve is inserted into the incision of the abdominal wall; the blocking part is positioned inside an abdominal cavity, the clamping part is positioned outside the abdominal cavity, and the blocking part plays a role in blocking to prevent the sleeve from being separated from the incision, and the clamping can be pressed on the abdominal wall in a turnover mode; and elasticity generated by the sleeve is extruded on the wall of the incision to play a role in sealing. The pneumoperitoneum closed device has a one-hole and multi-channel structure and is convenient to operate, and the operation cost is saved.

Description

technical field [0001] The invention relates to a pneumoperitoneum sealing device in surgical operations, in particular to a laparoscopic pneumoperitoneum sealing device for end-to-side anastomosis of the gastrointestinal tract and gastroesophagus with a tubular stapler in laparoscopic gastrointestinal surgery . Background technique [0002] After Kitano et al. reported the first laparoscopic-assisted distal gastrectomy in 1994, laparoscopic radical gastrectomy for early gastric cancer developed vigorously in Japan and South Korea; subsequently, Uyama et al. reported laparoscopic D2 radical gastrectomy for advanced gastric cancer in 1999. After more than 10 years of development, the technology of laparoscopic surgery for early gastric cancer has matured, and its short-term and long-term curative effect is comparable to that of open surgery. In China, due to the relatively low diagnosis rate of early gastric cancer, advanced gastric cancer accounts for a large proportion, ma...
