Description

An intra-abdominal exhaust device during endoscopic surgery

Technical field

The utility model belongs to the field of medical equipment and relates to an abdominal cavity exhaust device, in particular to an abdominal cavity exhaust device during endoscopic surgery.

Background technique

Endoscopic full-thickness resection (EFTR) refers to the removal of lesions and the entire thickness of the digestive tract wall under an endoscope. During the operation, in order to ensure a good surgical field of view and operating space, the endoscopist will deliver air into the stomach through the endoscope. Full-thickness resection will be accompanied by active gastric wall perforation or gastric wall defect. Gas in the stomach can enter the abdominal cavity through the gastric wall perforation or defect, causing a gradual increase in intra-abdominal pressure. On the one hand, the increase in intra-abdominal pressure will lead to gastric cavity filling. It is difficult, and more importantly, it will cause the diaphragm to rise, affecting the patient's respiratory and circulatory system, which poses a huge safety hazard. Therefore, effective abdominal exhaust is the guarantee for the smooth progress of EFTR surgery.

At present, the common clinical abdominal exhaust method is the syringe exhaust method, that is, after using a syringe to extract an appropriate amount of normal saline, the sterile puncture is performed 1 cm to the left or 1-2 cm to the right above the midpoint of the line connecting the umbilicus and the upper edge of the pubic symphysis. After puncture into the abdominal cavity, bubbles can be seen emerging from the syringe, which is then fixed with tape. This method is simple to use, but has certain shortcomings: 1. The normal saline in the syringe is directly connected to the abdominal cavity, and as the operation proceeds, the normal saline in the syringe will flow into the abdominal cavity, posing a risk of infection; 2. The abdominal cavity cannot be measured. Internal pressure; 3. When the syringe is removed, the liquid in the syringe will flow out directly from the needle; 4. It is difficult for a single person to fix the syringe.

In order to solve these problems, various improvement schemes have been proposed. For example, utility model patent CN213249337U discloses an abdominal exhaust device for endoscopic surgery, which includes a syringe with a piston and a piston rod inside. A needle is installed at the front end of the barrel; a pressure gauge is integrated in the middle of the syringe; an air outlet is located above the pressure gauge in the upper part of the syringe; a cap is screwed outwardly on the air outlet; physiological fluids are drawn into the syringe through the needle; Saline, the physiological saline liquid level is located below the sensing area of the pressure gauge, and the syringe handle of the syringe is vertically hung on the hanger through a hanging wire. However, this device must occupy valuable space on the operating table alone during surgery, and requires a dedicated operator to operate it, making it unable to be used in clinical practice. The applicant's previous patent CN217660175U also provided an abdominal exhaust combined device during endoscopic full-thickness resection, which includes a pig tail tube, a skin expansion device and an exhaust device. The exhaust device is a box structure. A portable buckle is provided on the outside, and a U-shaped internal pressure gauge, an anti-back-sucking bottle and an exhaust bottle are provided inside the exhaust device box. However, it was found that it occupies a large space, has a relatively complex structure, which results in high cost, and the operation is relatively cumbersome, so further improvements are necessary.
