Outward-turning type intestinal tract welding anastomat

Abstract

The invention discloses an outward-turning intestinal tract welding anastomat which comprises a handle assembly, a telescopic rod assembly and a circular ring welding head assembly. The handle assembly is connected with a soft tissue high-frequency welding device through a cable and then forms an output loop for high-frequency current with the circular ring welding head assembly. The circular ring welding head assembly comprises a far-end circular ring welding head and a near-end circular ring welding head, the far-end circular ring welding head comprises a far-end electrode plate, a far-end circular ring and a plurality of far-end hooks, the near-end circular ring welding head comprises a near-end electrode plate, a near-end circular ring and a plurality of near-end hooks, and the far-end electrode plate and the near-end electrode plate are arranged oppositely. The intestinal tract tissue at the two ends is fixed into the far-end circular ring welding head and the near-end circular ring welding head which share the same axis respectively, the mucosa and the mucosa are attached, then high-frequency current is applied to make protein to be separated out from the tissue at the joint, and heating is continued so that the protein between the tissue can tangle and agglutinate to form firm connection. The outward-turning intestinal tract welding anastomat is mainly used for intestinal tract anastomosing in the open type surgical process.

Description

technical field [0001] The invention relates to a stapler in the field of medical device research, in particular to an eversion type intestinal welding stapler. Background technique [0002] Circular stapler is a mechanical surgical tool for digestive tract reconstruction developed in the past 20 to 30 years. It mainly uses titanium or tantalum metal nails to fix intestinal tissue. Compared with the traditional needle and thread manual suture, the stapler can simplify the operation process, shorten the operation time, and make some operations that are difficult to expose and operate in a small space easier. The circular stapler is in the inverted anastomosis mode. During work, the staple cartridge assembly needs to be completely placed in the intestine, and pressure is applied to make the intestinal serosa at both ends fit together, and then the metal nail is activated to fix the soft tissue, and the excess stump is removed to form a Digestive tract reconstruction. The cir...

Problems solved by technology

In addition, when the circular stapler has no natural physiological entrance, working parts need to be placed in the incision on the side wall of the intestinal tract. After the end-to-end anastomosis of the intestinal tract is completed, the incision on the side wall needs to be closed, which increases the surgical trauma and surgery of the intestinal tract. chance of wild contamination
