Description

Technical Field

[0001] This utility model relates to the field of blood vessel clamping technology, and specifically to a blood vessel clamping device. Background Technology

[0002] In medical surgery, to avoid increasing the difficulty of the operation due to excessive bleeding or ruptured blood vessels in the target organ, the blood vessels connected to the target organ are first ligated and hemostatic using vascular clamps. The instrument used is called a clamp forceps. The clamp forceps are used by first inserting the clamp forceps into the human body, then clamping the blood vessel, and applying external force to tighten the clamp and block the blood flow to achieve the effect of hemostasis.

[0003] For example, utility model CN211300170U discloses a handheld portable vascular clamping device, specifically relating to the field of vascular clamp technology. It includes a fixing plate with a vascular clamping mechanism fixedly mounted at its bottom. The vascular clamping mechanism includes a connecting tube with two clamping shells on both sides. The clamping shells have a semi-circular cross-sectional shape and are made of PVC material. A protective layer is fixedly mounted inside each clamping shell, and a sealing ring is fixedly mounted on the inner wall of the protective layer. A flipping plate is fixedly mounted on the top of the clamping shell, and a limiting plate is fixedly mounted on one side of the flipping plate. This utility model, by setting a vascular clamping mechanism, allows for the rotation of an adjusting plate as needed. The adjusting plate, via a rotating shaft, drives a sealing column to rotate within a placement groove, aligning the flow port with the lumen of the connecting tube. This allows for control of blood flow from the blood vessel, enabling precise control of blood flow within the vessel as required.

[0004] In the process of developing this application, the following problems were found with this technology: Most existing vascular clamping devices clamp blood vessels one by one manually, which has a relatively simple function, long operation time, and easy fatigue of doctors. Moreover, the clamping device cannot be adjusted according to the size of the blood vessel, resulting in poor adaptability of the device. Furthermore, most existing devices cannot be adjusted according to the clamping position of the blood vessel, which greatly reduces the convenience of the device and reduces its practicality.

[0005] Therefore, a blood vessel clamping device is proposed. Utility Model Content
