Removable micro anastomosis sleeve

Abstract

The invention discloses a removable micro anastomosis sleeve, relating to a micro-conduit anastomosis therapeutic equipment and comprising a sleeve and a handle. The removable micro anastomosis sleeve is characterized by cutting a horizontal notch on the sleeve, processing a horizontal needle groove on the outer wall of the sleeve, processing a bolt coupling column at the needle groove-free end of the sleeve to be connected with a rod by a bolt and processing the handle on the rod. The invention is designed to solve problems of the prior art that manual suturing costs both time and manpower, has low speed and uneven effect, is apt to result in vascular occlusion or high percolation rate after realizing the anastomosis by suturing penetrated front and back walls of blood vessel and the like; mechanical anastomosis is immature, costs more money, has complicated operation, insecure anastomosis and more side effects and cannot be popularized easily; and the traditional sleeve anastomosis leaving the sleeve inside patient body is apt to cause uncomfortableness or damage of body and the like. The invention has the advantages of novel structure, easy operation, secure anastomosis effect, non-remainder, reliable-safe effect, low cost and the like. The invention can be regarded as the novel removable micro anastomosis sleeve integrating economical efficiency with practicality.

Description

technical field [0001] The removable microscopic anastomosis sleeve of the present invention relates to a microscopic duct anastomosis treatment device. Background technique [0002] Vascular anastomosis has always played a pivotal role in microsurgery. For example, in order to successfully complete a microsurgical operation such as replantation of a severed finger or skin flap transplantation, the application of an effective vascular anastomosis method plays a key role. [0003] In recent years, the development of minimally invasive surgery and transplant surgery requires the improvement of vascular anastomosis techniques. At present, the commonly used microvascular anastomosis methods in experimental research and clinical application include suture anastomosis, magnetic tube anastomosis, cannula anastomosis, thermocoagulation anastomosis, and adhesive anastomosis. Manual suturing is not only time-consuming and laborious, the suturing speed is slow and uneven, and it is ea...

AI Technical Summary

Problems solved by technology

It is used to solve the time-consuming and laborious manual suturing commonly used in the existing microvascular anastomosis, the suturing speed is slow and uneven, and it is easy to cause the anterior and posterior walls of the blood vessel to penetrate through the suture, resulting in vascular occlusion or high leakage rate after anastomosis; mechanical anastomosis methods are mostly Immature or high cost, complex operation, weak anastomosis, many side effects, and not easy to popularize; the traditional cannula anastomosis method will leave the surgical cannula in the patient's body, causing physical discomfort or injury to the patient
