Vascular clamp used in vascular surgery department

Abstract

The invention discloses a vascular clamp used in a vascular surgery department. The vascular clamp comprises a clamp module, an adsorption module and an adjusting module, wherein the clamp module comprises a pressing button, a pressure cylinder, a pressure spring, a pressure conveying tube, an execution telescopic cylinder and an execution telescopic rod; the pressure cylinder is connected with the outer surface of the pressing button in a sliding manner; the pressure spring is arranged between the bottom of the pressing button and the bottom of the inner wall of the pressure cylinder; the execution telescopic cylinder communicates with a part below the pressure cylinder through the pressure conveying tube; and the execution telescopic rod is moveably connected with the inner wall of the execution telescopic cylinder. Due to adoption of the adjusting module, when one vascular clamp block is adjusted, the other vascular clamp block can be driven to move together, then the time for adjustment can be shortened, and furthermore, the use efficiency of the device can be improved; due to adoption of the adsorption module, a blood vessel can be well adhered to surfaces of a blood vessel clamp cylinder and blood vessel clamp blocks, so that the blood vessel can be prevented from dissociation by accident in the operation process of a doctor, and furthermore, the use security degree of the device can be increased.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a blood vessel clamper for vascular surgery. Background technique [0002] Arteries originate from the heart, branch continuously, become thinner in diameter and thinner in wall, and finally divide into a large number of capillaries, which are distributed to various tissues and cells throughout the body. The capillaries rejoin and form veins, which eventually return to the heart. Arteries and veins are pipelines for transporting blood, and capillaries are places where blood and tissues exchange substances. Arteries and veins are connected through the heart, and blood vessels throughout the body form a closed pipeline. The distribution of blood vessels in the human body is often symmetrical and adapted to the function. Most of the large blood vessels run parallel to the long axis of the body, and are wrapped together with the nerves by connective tissue membranes to f...

Problems solved by technology

[0003] Aiming at the deficiencies of the prior art, the present invention provides a blood vessel clamper for vascular surgery, which solves the phenomenon that the surface of the blood vessel and the clamp will slide when the traditional clamp clamps the blood vessel, which is easy to cause being clamped The problem of blood vessels falling off, which interferes with the doctor's surgical operation
