Abstract
Description
Technical Field
[0001] The invention relates to the technical field of medical devices, and in particular to a renal blood vessel clamp which is easy to adjust. Background Art
[0002] Vascular clamps play an important role in medical procedures, especially in controlling bleeding, but their use is also accompanied by some potential disadvantages or limitations.
[0003] The vascular clamp may not be able to adapt to all blood vessel diameter ranges, especially when the blood vessel diameter is too small or too large, which may lead to poor clamping effect. For renal blood vessels, it is difficult to accurately measure and control the clamping force of the vascular clamp on the blood vessel. Excessive clamping force may damage the blood vessel, and too little clamping force may not be able to effectively stop bleeding. At the same time, blood vessels vary in thickness and cannot be perfectly adapted to different patients.
[0004] For this reason, we propose a renal vascular clamp that is easy to adjust. Summary of the invention
