Degradable microvascular anastomat

Abstract

The invention relates to a degradable microvascular anastomat. The degradable microvascular anastomat comprises a right ring body and a left ring body, the right ring body and the left ring body are the same and are oppositely arranged; the right ring body and the left ring body respectively comprise a right rear ring and a left rear ring; the left rear ring comprises a left supporting cylinder used for supporting a left blood vessel, and the right rear ring comprises a right supporting cylinder used for supporting a right blood vessel. A right clamping ring and a left clamping ring which are used for clamping blood vessels are arranged on the outer sides of the right supporting cylinder and the left supporting cylinder in a sleeving manner; the right clamping ring and the left clamping ring respectively comprise a right clamping hook and a left clamping hook; the right clamping hook is used for being clamped on the left ring body, and the left clamping hook is used for being clamped on the right ring body. The right ring body and the left ring body are tightly buckled through clamping of the right clamping hook and the left clamping hook, so that the left blood vessel and the right blood vessel are matched, and the situation that the blood vessel is torn due to loosening of the anastomat is avoided.

Description

technical field [0001] The invention relates to the field of microvascular staplers, in particular to a degradable microvascular stapler. Background technique [0002] The technique of vascular anastomosis is the basis of microsurgery and the whole surgery. The ideal vascular anastomosis method should be easy to master, easy to operate, short anastomosis time, and less harmful to blood vessels. Currently, vascular anastomosis techniques mainly include suture anastomosis technique, vascular mechanical anastomosis technique, and vascular bonding technique. Suture anastomosis techniques and mechanical anastomosis techniques are commonly used in clinical practice at present. Although the suture anastomosis technique is currently recognized as the standard method of vascular anastomosis, there are still some problems: cumbersome operation, long operation time, high requirements for doctors' skills, and it is difficult to master the essentials of operation in a short time without...

Problems solved by technology

[0004] The purpose of the present invention is to provide a degradable microvascular stapler to solve the problem that when the existing products are violently involved and squeezed by the outside world, a pair of rings of the stapler are easy to loosen and even separate, resulting in unstable vascular anastomosis. Even the problem of tearing blood vessels
