A Portable Hepatic Portal Blocker

Abstract

The present invention relates to the technical field of medical aids, in particular to a portable hilar blocker, comprising: a guide tube for supplying a blocking belt to a position to be blocked; a locking part arranged in the middle of the discharge ends of two channels position; the clamping part, including the seat body, two symmetrically arranged connecting rod groups and a one-way locking structure; one end of the connecting rod group is connected with the force application part to realize the clamping of the blocking belt, and the one-way locking structure is used In order to maintain the clamping action; the seat body is connected with the guide tube through the hook structure. After the connection relationship is released, the movement of the guide tube makes the blocking belt at the end of the channel form a ring structure, and the size of the ring structure is controlled by the channel feeding end. The control of the broken belt realizes the regulation. In the present invention, through the improvement of the structure of the hepatic hilum blocker, a more convenient way of forming a ring for the blocking band is obtained. The size of the ring structure is easy to control, and only the structural form of the guide tube and the clamping part need to be changed during the application process. , which can be commonly used in laparoscopic and open operations.

Description

technical field [0001] The invention relates to the technical field of medical aids, in particular to a portable hepatic portal blocker. Background technique [0002] Portal hepatic occlusion is an effective way to control bleeding during liver surgery in clinical practice. The liver is the largest solid organ in the human body, because of its unique dual blood supply from portal vein and hepatic artery, its blood supply is extremely rich. In liver surgery, different degrees of bleeding will occur during and after the operation, and the amount of bleeding is positively correlated with the incidence of postoperative complications and mortality. It is especially important to control and reduce bleeding during liver surgery, and the existing hepatic portal obstruction The operation of the breaking device is relatively complicated, and time is wasted in repeated operations. [0003] In view of the above situation, based on years of rich practical experience and professional kno...
