Abstract

The invention belongs to the technical field of medical instruments, and discloses a blood vessel anastomat for a kidney transplantation operation. An inner tube main body comprises a left inner tube; fixed teeth fixedly connected with the left inner tube are arranged on the left inner tube; a middle tube fixedly connected with the left inner tube is arranged on the left inner tube; a right inner tube fixedly connected with the middle tube is arranged on the middle tube; fixing teeth fixedly connected with the right inner tube are arranged on the right inner tube; and hollow grids are arranged on the left inner tube, the middle tube and the right inner tube. According to the blood vessel anastomat, through the inner tube main body made of a shape memory material, the left inner tube and the right inner tube are expanded at phase-change temperature, and the middle tube is shrunk at the phase-change temperature, to make blood vessels on the two sides attached.

Description

technical field [0001] The invention belongs to the technical field of medical instruments, and in particular relates to a blood vessel stapler for kidney transplantation. 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...
