Binding device for surgery

Abstract

The invention relates to an instrument used for binding in surgery. The head of binding device is equipped with a radial emitting device for binding tissue. The condition of intestinal canal tissue after operation is similar to that of before operation, the inner passage does not become smaller, which is convenient for taking out apparatus and good for healing of tissue. The invention overcomes many shortcomings of current similar device and increases operation effect greatly.

Description

technical field [0001] The invention relates to a binding instrument used in surgical anastomosis, in particular to a surgical binding instrument which uses radial emission to implement internal anastomosis, and belongs to the technical field of medical instruments. technical background [0002] Surgical stapler is a medical device often used in surgical operations on intestinal and other physiological tissues. The difference in the performance of the instrument plays a vital role in the overall surgical effect. In the prior art, the firing direction of the nail is basically consistent with the axial direction of the tissue during the anastomosis, which can be divided into the following three ways: [0003] 1. Axial inward anastomosis. like figure 1 As shown, the two sections of tissue 1a and 1b are convergent, forming an anastomotic ring 2 inside the tissue. This is a relatively traditional anastomotic method, and there are many corresponding anastomotic instruments. Its...

AI Technical Summary

Problems solved by technology

The disadvantages are: it is necessary to open the cardia near the anastomotic point during the operation; the anastomotic ring stays in the tissue cavity after the operation, narrowing the internal passage of the tissue, which is not conducive to the removal of postoperative instruments, which is easy to cause surgical complications, and is not conducive to postoperative body The recovery of tissue function will bring obvious side effects to the patient; third, this anastomosis method is not conducive to postoperative examination

The advantages of this anastomosis method are: there is no need to open the cardia during the operation, the postoperative inspection is convenient, the inner passages of the intestinal diameter and other tissues are not affected, and it is convenient to take out the instruments after the operation; the biggest disadvantage is that the body bleeding generated during the operation will enter the in body fluids, unable to excrete

Its disadvantages are: the body tissue at the anastomosis is always in a tight state, which is not conducive to postoperative tissue healing; the manufacture of surgical instruments is relatively complicated; postoperative inspection is still inconvenient
