Problems solved by technology

[0003] However, due to the abundance of small blood vessels around the renal arteries, the free arteries need to be carefully manipulated, and the above manipulation steps unintentionally prolong the operation time and increase the risk of bleeding
[0004] Furthermore, the clamping force of the occluder currently used to clamp blood vessels cannot be adjusted. If the blood flow during the operation is large, one or more occluders need to be added, and the addition of an artery blocking clip requires free Longer renal arteries to provide more space, which can lead to increased surgical risk and less maneuverability

Abstract

The present application provides an adjustable blood vessel blocker, which includes a clamping body and a clamping set. The clamping body has a plurality of first positioning parts, and the clamping set has a second positioning part. When the clip When the holding body is clamped on the blood vessel or the blood vessel and its surrounding tissue, the clamping sleeve can be sleeved on the clamping body, and by making the second positioning part different from the first The positioning part cooperates to adjust the relative position of the clamping set and the clamping part, thereby adjusting the clamping force of the clamping part.

Description

technical field [0001] The embodiment of the present application relates to a medical device, in particular to an adjustable blood vessel blocker. Background technique [0002] In traditional laparoscopic partial nephrectomy, after separating the space between the renal parenchyma and perirenal fat, it is necessary to separate the fat tissue at the renal hilum, and then follow the pulse of the renal artery to find and locate the renal artery, and after further opening the vascular sheath , use tools such as ultrasonic scalpel, separating forceps, and right-angle forceps to fully expose the renal artery freely, and then place the vascular blocker. [0003] However, due to the abundance of small blood vessels around the renal arteries, the free arteries need to be carefully manipulated, and the above-mentioned manipulation steps will unintentionally prolong the operation time and increase the risk of bleeding. [0004] Furthermore, the clamping force of the occluder currently...
