Device for sealing abdominal wall lancing for peritoneoscope operation

Abstract

The invention discloses a notch sealer of abdominal wall of laparoscope surgery, which consists of elastic bushing ring (1) and soft sleeve (2), wherein one end of the soft sleeve (2) connects the elastic bushing ring (1) and the other end is opening. The invention has simple and reasonable structure, convenient usage, low cost, which can seal the notch rapidly and rebuilds pneumoperitoneum to finish the reconstruction of digestive tract in the internal and external linked abdominal cavity under pneumoperitoneum condition.

Description

technical field [0001] The invention relates to auxiliary equipment for medical operations, in particular to an abdominal wall incision sealing device for laparoscopic operations. Background technique [0002] Laparoscopic surgery has the advantages of small trauma, fast recovery, and good field of vision, and has been widely used in clinics. Laparoscopic cholecystectomy, laparoscopic gynecological tumor resection, and laparoscopic radical resection of colorectal cancer have gradually replaced traditional open surgery. abdominal surgery. Gastric tumor resection and digestive tract reconstruction are completed by poking holes under laparoscopy, and finally a small incision is made to take out the specimen, which is called total laparoscopic gastrectomy. High, difficult to promote. After gastric tumor resection is completed by poking a hole under laparoscopy, an incision is made to take out the specimen, and the incision is used to complete the reconstruction of the digestiv...

AI Technical Summary

Problems solved by technology

Taking laparoscopic radical gastrectomy as an example, laparoscopic digestive tract reconstruction, especially after proximal gastrectomy and total gastrectomy, is very difficult

Since surgical instruments can only enter through a few small holes with a diameter of 0.5 cm or 1 cm on the abdominal wall, special instruments for laparoscopic surgery must be used. Prolonged time, reduced safety, a substantial increase in the cost of surgical instruments, and prolonged abdominal incisions severely restrict the widespread use of laparoscopic gastrointestinal surgery

The resected specimen in laparoscopic gastric cancer surgery must be taken out through an incision on the abdominal wall, usually a midline incision on the upper abdomen. Depending on the size of the tumor, the incision is about 3 to 5 cm long; laparoscopic distal gastrectomy can be completed basically without enlarging the incision Gastrointestinal anastomosis, however, the reconstruction of the digestive tract after laparoscopic proximal gastrectomy and total gastrectomy is relatively complicated, and large-volume instruments such as tubular staplers for laparotomy must be used, so the incision must be extended to 8-10 cm accordingly to complete

Even so, the incision of 8-10 cm is still too small, the surgical field of view is not well exposed, and the operation is still relatively difficult

Furthermore, if the pneumoperitoneum with a pressure of about 12 mm Hg (0.09 Pa) is to be established after the opening of the abdominal wall to continue the operation, unless the incision is temporarily sutured. Finally, the whole operation time and the patient's anesthesia time are prolonged, and the damage to the incision site is also increased.
