Multifunctional anastomat for vascular surgery

Abstract

The invention discloses a multifunctional anastomat for vascular surgery, and belongs to the field of medical auxiliary instruments, the multifunctional anastomat comprises an anastomosis fixing seat and a supporting ring, a fixing seat overturning groove is formed in the center of the upper end of the anastomosis fixing seat, and a supporting ring penetrating groove is formed in the center of the bottom of the fixing seat overturning groove; the bottom of the supporting ring penetrating groove is obliquely arranged towards the side face of the anastomosis fixing base in a penetrating mode, the first end of the supporting ring is fixedly connected to the side, opposite to the bottom of the supporting ring penetrating groove, of the anastomosis fixing base, the two sides of a blood vessel wound are fixed through a wound fixing base on the anastomosis fixing base, and then the inner wall of a blood vessel is supported through the supporting ring. By means of the installation mode of firstly fixing and then supporting, it is guaranteed that a blood vessel wound is fixed in a contraction state, fixing is firmer, the circulation area in the blood vessel is guaranteed, normal circulation of blood in the blood vessel at the wound position during healing is guaranteed, the device can adapt to the high-pressure working environment of the blood vessel, and the requirement for suture repair of the axial wound of the blood vessel wall is met.

Description

technical field [0001] The invention relates to the field of medical auxiliary instruments, in particular to a multifunctional stapler for vascular surgery. Background technique [0002] In vascular surgery, sometimes the blood vessels are operated on, and the blood vessels need to be anastomosed after the operation, and the stapler can effectively anastomos the blood vessels, so a multifunctional stapler for vascular surgery is required. [0003] The existing multifunctional staplers for vascular surgery have shortcomings. Some multifunctional staplers for vascular surgery fix two blood vessels on an anastomotic ring, and control the two anastomotic rings through the stapler to make the two anastomotic rings close to each other for a certain period of time, and then the two anastomotic rings are fixed. The anastomotic ring and the stapler are separated and disassembled, and then the two anastomotic rings always maintain the anastomosis between the two blood vessels. However...

AI Technical Summary

Problems solved by technology

[0003] There are deficiencies in the existing multifunctional staplers for vascular surgery. Part of the multifunctional staplers for vascular surgery fix two sections of blood vessels on the anastomotic ring. The anastomotic ring and the stapler are separated and disassembled, and then the two anastomotic rings always maintain the anastomosis between the two blood vessels. However, the anastomotic ability of the anastomotic device in the prior art is insufficient for the axial opening of the side, and cannot meet the anastomosis of the side injury of the blood vessel. Moreover, the existing vascular staplers are all evolved from gastrointestinal staplers, and the difference between blood vessels and gastrointestinal tracts is that they are subjected to greater pressure during blood delivery, and the contraction rate of blood vessels is relatively large. , the contracted blood vessel is not easy to install, and the anastomosis is easy to be stretched when the internal pressure of the blood vessel increases and expands after mild, resulting in secondary damage. Therefore, it is urgent to improve the above problems. A multifunctional stapler for vascular surgery to solve the above problems
