Bipolar radiofrequency intestinal tract anastomat and working method

Abstract

The invention relates to a bipolar radiofrequency intestinal tract anastomat and a working method. The anastomat comprises a near-end structure, a far-end structure and a radiofrequency energy generator, wherein the near-end structure is placed at the near end of an intestinal tract; the far-end structure is divided into a head portion and a handle portion, is located at the far end of the intestinal tract, and connects a positive pole with a negative pole of the radiofrequency energy generator through a guide wire inside the handle portion; and after the near-end structure is in butt joint with the far-end structure, the far-end structure becomes the negative pole, and a metal circular ring of the near-end structure is the positive pole. The intestinal tract is respectively sleeved on the near-end structure and the far-end structure, a portion needing anastomosis is collected to be attached to the metal circular ring of the near-end structure and a metal circular ring of the far-end structure, after sleeving, the metal circular ring of the near-end structure and the metal circular ring of the far-end structure form a circuit with the positive pole and the negative pole, intestinal tract anastomosis is completed after energization, after electricity is cut off, an internal push-type cutter is triggered through a switch of the handle portion, and residual tissue in the intestinal tract is cut off to guarantee smoothness of the intestinal tract. The anastomosis portion is continuous, operation time is short, no foreign matters are left in the intestinal tract after an operation, and safety of the anastomosis process is guaranteed.

Description

technical field [0001] The invention relates to an electrosurgical minimally invasive medical instrument, in particular to a bipolar radio frequency intestinal stapler and a working method. Background technique [0002] The incidence of colorectal cancer has been increasing rapidly in recent years, ranking the fourth or fifth among malignant tumors in my country. In colorectal surgery, after resection of the diseased (tumor) intestinal segment, it is usually necessary to anastomose the intestinal tract to restore the continuity of the digestive tract, that is, intestinal anastomosis. [0003] Commonly used anastomosis methods include traditional manual suture anastomosis and metal staple anastomosis. The latter commonly includes circular staplers and linear cutting staplers. Their appearance facilitates surgical operations, shortens surgical time, and enables Some anus-preserving operations, such as low anterior rectal resection and ileal pouch-anal canal anastomosis, which...

AI Technical Summary

Problems solved by technology

However, because titanium metal nails have the same problems of discontinuous tissue apposition and foreign body residue as manual suture, the incidence of postoperative anastomotic leakage, bleeding and other complications has not been reduced. Therefore, postoperative anastomotic dehiscence, bleeding, The incidence of complications such as anastomotic leakage and stenosis has not been reduced, and all anastomotic site requirements cannot be met

For different tissue types, thicknesses and locations, it is necessary to replace the anastomotic instruments, resulting in complicated and expensive operations
