Serrefine

Abstract

The invention provides a serrefine. The serrefine comprises a serrefine body, wherein the serrefine body comprises a main force storing piece; the main force storing piece adopts an arc shape; an elastic piece which extends to the other end of the main force storing piece facing the upper part of an arch opening is connected to one end of the main force storing piece; the elastic piece is arc-shaped, and the arch opening of the elastic piece faces the main force storing piece; a supporting part is arranged at a position opposite to one end which is connected with the main force storing piece, of the elastic piece; a notch is formed in a position opposite to one end which is connected with the elastic piece, of the main force storing piece, and faces the connecting end of the main force storing piece and the elastic piece; and control ears which are fitted with operating forceps to extrude the main force storing piece and the elastic piece are arranged at middle section positions of one surface back to the elastic piece, of the main force storing piece, and one surface back to the main force storing piece, of the elastic piece. The serrefine disclosed by the invention has the advantages of being good in clamping effects and small in damage to blood vessels and can effectively avoid the situation that in the clamping process of the blood vessels, the serrefine is slipped and deviated.

Description

Technical field [0001] The present invention relates to the field of medical equipment, in particular to a blood vessel clamp. Background technique [0002] There are many types of vascular clamps. Among them, disposable vascular clamps (ligated vascular clamps) are fastened by surgical forceps when in use, and have a unique nail-free design. The arc "V" opening structure wraps around the tissue for clamping, and the closed buckle is used for clamping. When clamping, the operator can perceive the clamping state, but there is a "V"-shaped cut angle when clamping, which makes it easy to slide the blood vessel away from the clamping port. To increase friction, this type of blood vessel clamp is often set on the clamping surface Zigzag anti-skid strip, but this will cause the vascular clamp to slide friction with the blood vessel before clamping or squeeze and damage the blood vessel after clamping. At the same time, because it is made of plastic, the clamping force is difficult to e...

Problems solved by technology

[0005] In the above structure, the opening of the arch opening of the main power storage piece is controlled by pushing the arc-shaped elastic piece, and the two ends of the elastic piece are pushed by the reverse contraction of the bow opening of the main power storage piece after the elastic piece passes through the straight line dead point position , so that the elastic sheet is reversely bent towards the inner side of the arch of the main power sheet to realize the squeezing and clamping of blood vessels. Since the elastic sheet bends its two ends through the arch of the main power sheet to make it bend to flatten the blood vessel, Its elasticity can be adaptively adjusted according to the thickness and thickness of the blood vessel wall. At the same time, when the blood vessel is squeezed, the blood vessel is located at the bottom of the arch opening of the main power storage piece, so it can play a good centering role and prevent the blood vessel from sliding and deviation when clamping. , to solve the situation that the blood vessels are easy to slip when the existing blood vessel clamp is clamped, and the blood vessels are easy to be damaged if the rigidity is too large; when separating, only need to pull the two control ears in the direction away from each other, so that the elastic piece can be straightened and pushed away. The bow mouth of the power storage piece is recovered after the elastic piece reversely crosses the dead point of the line, and the elastic piece is further pulled by the control ear to separate the support part from the notch to form an open loop, which is convenient for the clip body to be removed from the blood vessel. remove
