Rapid blood vessel anastomosis device

Abstract

The invention discloses a rapid blood vessel anastomosis device. The rapid blood vessel anastomosis device comprises a first end sleeve, a second end sleeve, a nail hammer and a handheld suturing nail percussion assembly, wherein the first end sleeve and the second end sleeve are coaxially arranged in an end-to-end opening and closing mode. The first end sleeve comprises a nail bin and the nail hammer, the nail bin is provided with a plurality of nail bin holes which are through along the axial direction and used for containing suturing nails, and suturing nail pushing pieces at one end of the nail hammer are used for being inserted into the nail bin holes in a one-to-one correspondence and matched mode from one end of the nail hammer; the second end sleeve is provided with a plurality of nail anvils; and the handheld suturing nail percussion assembly is used for being connected with the nail hammer of the first end sleeve and the second end sleeve, and clamping force is applied by holding the handheld suturing nail percussion assembly by a hand, so that the suturing nails in the corresponding nail bin holes are pushed out by the suturing nail pushing pieces of the nail hammer, and blood vessel suturing is conducted under the cooperation of the nail anvils. The rapid blood vessel anastomosis device can be used for conveniently and rapidly connecting blood vessels in a narrow in-vivo space during organ transplantation, the blood vessel anastomosis quality is high, the activity of an organ after transplantation can be improved, and the risk of transplantation complications is lowered.

Description

technical field [0001] The invention relates to the technical field of medical surgical devices, in particular to a rapid blood vessel anastomosis device. Background technique [0002] After nearly a century of development, organ transplantation has become an ultimate means of treating end-stage organ failure. Vascular anastomosis is one of the essential steps in organ transplantation. During the process of vascular anastomosis, the transplanted organ needs to be put into the patient’s body, and the transplanted organ will enter the environment of 37°C from the original cold storage state. The shorter the process, the better; The interruption of local blood flow will cause some related organs of the body to be in a state of relative congestion. This process will also have a corresponding impact on these organs. Therefore, the shorter the operation time, the smaller the impact on other organs. [0003] Due to the different technical levels of surgeons, even the best surgeon...

AI Technical Summary

Problems solved by technology

Although the existing vascular stapler achieves the end-to-end anastomosis of some blood vessels, the metal ring will be left at the anastomosis port after the anastomosis, and the metal ring may be deflected under pressure in the body, which will affect the patency of blood flow

Therefore, this vascular stapler has not been applied to the field of organ transplantation so far.
