Description

Abdominal cavity exhaust device in endoscope operation

Technical Field

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

Background

Endoscopic total resection (EFTR) refers to the endoscopic resection of a lesion along with the total layer of the wall of the digestive tract. During operation, to ensure a good surgical field and space, the endoscopist will blow air through the endoscope into the stomach. When the full layer is resected, active gastric wall perforation or gastric wall defect is accompanied, gas in the stomach can enter the abdominal cavity through the gastric wall perforation or defect, so that the intra-abdominal pressure is gradually increased, on the one hand, the intra-abdominal pressure can cause difficulty in filling the gastric cavity, and on the other hand, the diaphragm can be lifted up, the respiratory and circulatory system of a patient are affected, and huge potential safety hazards are caused. Thus, effective abdominal evacuation is a guarantee that EFTR surgery is performed successfully.

The current common abdominal cavity exhaustion method is a syringe exhaustion method, namely, after a proper amount of physiological saline is extracted by a syringe, the syringe is successfully punctured into the abdominal cavity after the puncture of the umbilical region and the central point of the upper edge connecting line of pubic symphysis is disinfected and the upper edge is 1 cm far left or 1 cm to 2cm far right, and then the syringe is fixed by an adhesive tape. The method has the advantages of simple material taking, but has certain disadvantages: 1. the normal saline in the injector is directly communicated with the abdominal cavity, and along with the operation, the normal saline in the injector flows into the abdominal cavity, so that the risk of infection exists; 2. the intra-abdominal pressure cannot be measured; 3. when the syringe is pulled out, the liquid in the syringe can directly flow out from the needle head; 4. it is difficult for a single person to secure the syringe.

In order to solve the problems, various improvements have been proposed, for example, patent CN213249337U discloses an laparoscopic surgery abdominal cavity exhaust device, which comprises a syringe, a piston and a piston rod are arranged in the syringe, and a needle is arranged at the front end of the syringe; the middle part of the needle cylinder is integrated with a pressure gauge, an air outlet hole is formed in the upper part of the needle cylinder and is externally screwed with a hole cap, physiological saline is pumped into the needle cylinder through a needle head, the liquid level of the physiological saline is located below an induction area of the pressure gauge, and a needle cylinder handle of the needle cylinder is vertically hung on a hanging bracket through a hanging wire. However, the device needs to occupy precious operating table space independently in operation, and needs to be operated by special persons, so that the device cannot be used for clinical practice. The applicant also provides an abdominal cavity exhaust combination device in endoscopic total laminectomy in prior art in CN217660175U, which comprises a pigtail tube, a skin expanding device and an exhaust device, wherein the exhaust device is of a box structure, a portable buckle is arranged on the outer side of the exhaust device, and a U-shaped inner pressure gauge, a suck-back prevention bottle and an exhaust bottle are arranged in the box of the exhaust device.
