Jejunum coloproctia catheterization device used under laparoscope

Abstract

The invention provides a jejunum coloproctia catheterization device used under a laparoscope. The device comprises a percutaneous suture guider, a puncture needle, a guide wire and a nutrition tube, wherein the percutaneous suture guider is a thin rod, the pointed end of the thin rod is provided with a narrow and inwards-concave clamping opening, the puncture needle is of a hollow thin tube structure with a pointed end, the guide wire can penetrate into the puncture needle, the nutrition tube comprises a main tube body and a branch tube body extending outwards from the main tube body, the branch tube body is communicated with the main tube body, the branch tube body and the main tube body share an inlet, and the inside of the portion, behind a joint of the main tube body and the branch tube body, of a main tube of a drainage tube is provided with a one-way valve used for preventing liquid from flowing out from the outlet end of the main tube. Jejunum catheterization can be improved under the laparoscope, suture operations do not need to be carried out in the narrow space of the abdominal cavity, a suture can be led out of the abdominal wall through the percutaneous suture guider to be bound, operations are convenient to achieve, fixation is firm, and a patient has no adverse reactions after an operation and can recover quickly.

Description

technical field [0001] The application of the present invention relates to a laparoscopic fistula tube insertion device, which belongs to the technical field of medical devices. Background technique [0002] Jejunostomy is a temporary partial ostomy, mostly used for intubated ostomy. Its indications include pyloric obstruction, duodenal fistula, gastrointestinal anastomotic fistula, malnutrition; esophageal stenosis, inability to eat, systemic malnutrition, and the stenosis cannot be relieved by surgery; pancreatic head, ampullary carcinoma caused obstruction In severe jaundice, resection cannot be performed, and internal biliary drainage is unconditional, bile can be drained through the external biliary tract, and then returned to the intestinal cavity through jejunostomy; acute severe pancreatitis is estimated to be unable to eat in a short period of time after surgery, and jejunostomy can be used. Fistula supplement nutrition. [0003] Conventional jejunostomy uses an u...

Problems solved by technology

[0003] Conventional jejunostomy uses an upper left incision through the rectus abdominis, followed by steps such as searching for the jejunum, placing a catheter, suturing the fistula, fixing the bowel, and suturing. The rubber tube is more harmful to the patient; there are also laparoscopic jejunostomies, which need to pull the jejunum to the left lower abdominal wall in a small operating space for suturing with a total of 4 stitches, which is quite difficult and time-consuming.
