Problems solved by technology

[0002] In surgical operations on solid organs with rich blood vessels, intraoperative bleeding control is often the key to the success of the operation: on the one hand, excessive bleeding is often the main cause of serious complications; on the other hand, prolonged Blood flow occlusion or ischemia-reperfusion process can also lead to serious organ damage

Abstract

The invention provides a cavity tube adjusting instrument which mainly comprises a body, a first surrounding piece and a second surrounding piece, wherein the first surrounding piece and the second surrounding piece are movably connected with the body. Wherein at least one of the first surrounding piece and the second surrounding piece is provided with a locking structure, the locking structure can enable the first surrounding piece and the second surrounding piece to be combined with each other so as to form a surrounding part surrounding a target lumen in the circumferential direction, and the first surrounding piece and the second surrounding piece can synchronously reciprocate relative to the body so as to adjust the sectional area of the surrounding part. And the cross section of the target cavity tube is deformed to different degrees according to different sectional areas of the surrounding part. Therefore, the flow rate of the liquid in the target cavity tube can be conveniently and accurately regulated and controlled, and the flow rate regulating device has the advantage of being short in operation stroke.

Description

technical field [0001] The embodiments of the present application relate to the technical field of medical devices, in particular to a lumen adjustment device. Background technique [0002] In surgical operations on solid organs with rich blood vessels, intraoperative bleeding control is often the key to the success of the operation: on the one hand, excessive bleeding is often the main cause of serious complications; on the other hand, prolonged Blood flow occlusion or ischemia-reperfusion can also lead to serious organ damage. Both states can lead to the patient's death. Therefore, bleeding control has become a key technical point that limits the development of surgical techniques. [0003] Therefore, with the development of minimally invasive surgery, laparoscopic hepatectomy puts forward higher requirements on bleeding control technology during the operation. Contents of the invention [0004] In view of the above problems, the present application provides a lumen a...
