Portable hepatic portal occlusion device

Abstract

The invention relates to the technical field of medical auxiliary instruments, in particular to a portable hepatic portal occlusion device. The device comprises a guide tube used for supplying an occlusion band to a to-be-occluded position, a locking part arranged between the discharging ends of two channels, and a clamping part which comprises a seat body, two connecting rod groups arranged symmetrically and a one-way locking structure, wherein one end of each connecting rod group is connected with a force application part to clamp the occlusion band; the one-way locking structure is used forkeeping a clamping action; and the seat body is connected with the guide tube through a hook body structure. The occlusion band at the tail ends of the channels forms a ring body structure through movement of the guide tube after a connection relation is removed, and the size of the ring body structure is adjusted by controlling the occlusion band through the feeding ends of the channels. According to the invention, a relatively convenient ring formation mode for the occlusion band is obtained by improving the structure of the hepatic portal occlusion device, the size of the ring body structure is convenient to control, and the hepatic portal occlusion device can be universally used in laparoscopic and open-state operations only by changing the structural forms of the guide tube and the clamping part in an application process.

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...
