Pancreas-intestine external drainage silicone III pancreas-intestine stent

Abstract

The invention provides a pancreas-intestine external drainage silicone III pancreas-intestine stent. The pancreas-intestine external drainage silicone III pancreas-intestine stent comprises a drainage tube and a stent tube, wherein a convex head is arranged at the joint of the drainage tube and the stent tube, the side, towards the drainage tube, of the convex head is hemisphere-shaped, and the side, towards the stent tube, of the convex head is vertical-plane-shaped; a plurality of rows of convex spines are arranged on the outer side wall of the stent tube, a plurality of convex spines are arranged in each row, each row of convex spines inclines towards the convex head, and a gap is reserved between the first row of convex spines and the vertical plane of the convex head, the closer the convex spines are to the convex head, the denser the convex spines are, and the farther the convex spines are to the convex head, the sparser the convex spines are; a plurality of stent holes are formed in the wall of the stent tube, and the pancreas-intestine stent is made of silicone III. The pancreas-intestine external drainage silicone III pancreas-intestine stent is simple in structure, convenient to use and obvious in effect, through the reconstruction of preoperative image data, the pancreas-intestine stent tube with the size matched with the size of the individual pancreiatic duct of a patient is made through the external drainage technology, through the stent tubes with the convex spines and the convex heads, the sutureless anastomosis can be realized, thus the risks of leakage and stenosis are reduced, and meanwhile, the operation difficulty and risk are greatly reduced.

AI Technical Summary

Benefits of technology

This patented method allows medical professionals to create customizable temporary catheter systems called PENGLENS (Plastic Exalculatory Network) tubes used during endovascular procedures like gastroenterology and liver transplantations without having to cut open up any parts inside them. These special plugs have small holes near their ends, allowing liquids from outside body fluoresce when exposed to light. They allow liquid to flow through while preventing airflow into these tiny spaces around the plugged area. By removing all necessary components afterward, this system becomes easier to operate than previous methods requiring cutting off material beforehand. Overall, this new technique simplifies the procedure process and improves its overall success rate compared to existing techniques.

Problems solved by technology

This patents describes various methods for improving the success ratio and effectiveness of conventional liver surgeries performed without causing complicationes associated with other procedures including laproscopic enterocervix dysfunction and perforating bowel syndrome. Current options include enzyme ligase bonding techniques, radiofrequency ablation, ultrasonography, microsurgery, etc., each having their own limitations and drawbacks.
