Abstract

The utility model discloses a tissue ligation clip, which belongs to the field of medical appliances. The clamping device comprises an upper clamping arm and a lower clamping arm, wherein the tail ends of the upper clamping arm and the lower clamping arm are fixedly connected, the front ends of the upper clamping arm and the lower clamping arm are mutually locked and fixed through a locking mechanism, and clamping surfaces of the upper clamping arm and the lower clamping arm are mutually matched wavy curved surfaces. In the tissue ligation clip provided by the utility model, the clamping surface of the upper clip arm and the lower clip arm is a wave-shaped curved surface, so that the tissue can be better pressed after the ligation clip is closed, thereby achieving good ligation effect; the intermeshing action of the teeth and sockets further enhances the ligation of the tissue; and the convex teeth and the tooth sockets are arranged in multiple rows, so that the pressing force on the tissues is increased, and the pressing effect is improved.

Description

Tissue ligation clamp

Technical Field

The utility model relates to the technical field of medical equipment, in particular to a tissue ligation clip.

Background

Tissue ligating clips are generally U-shaped with a latch. Generally made of chemical synthesis or high molecular materials. And (4) providing the product in a sterile manner. Is disposable. Used for closing tubular tissue structures without removal after surgery.

The position that the inside clamp of the tissue of clamp was closed on the tissue ligature clamp on the existing market is two radian limits, and the radian edge distributes the stuck point, and inside laminating has the gap when the tissue ligature clamp uses, and closed tissue can exist the condition that can not close completely.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a tissue ligature clamp to solve the tissue ligature clamp on the existing market, the inside laminating has the gap when the inside position of clamping closed tissue of clip is two radian limit tissue ligature clamps uses, closed tissue can have the problem that can not be closed completely.

In order to solve the technical problem, the utility model provides a tissue ligation clamp, including last arm lock and lower arm lock, go up the tail end fixed connection of arm lock and lower arm lock, the front end is fixed through locking mechanical system mutual locking, go up the arm lock with the clamping face of lower arm lock is the wave curved surface that matches mutually.

Optionally, a first anti-slip line is arranged on the wavy curved surface.

Optionally, a plurality of teeth are arranged on one clamping surface of the upper clamping arm and the lower clamping arm along the length direction of the clamping arm, and a plurality of tooth sockets matched with the teeth are arranged on the other clamping surface along the length direction of the clamping arm.

Optionally, the teeth and the tooth sockets are at least provided with 2 rows on the clamping surfaces of the upper clamping arm and the lower clamping arm along the length direction.

Optionally, a plurality of the convex teeth are provided with second anti-skid lines.

In the tissue ligation clip provided by the utility model, the clamping surface of the upper clip arm and the lower clip arm is a wave-shaped curved surface, so that the tissue can be better pressed after the ligation clip is closed, thereby achieving good ligation effect; the intermeshing action of the teeth and sockets further enhances the ligation of the tissue; and the convex teeth and the tooth sockets are arranged in multiple rows, so that the pressing force on the tissues is increased, and the pressing effect is improved.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments. The advantages and features of the present invention will become more fully apparent from the following description and appended claims. It should be noted that the drawings are in simplified form and are not to precise scale, and are provided for convenience and clarity in order to facilitate the description of the embodiments of the present invention.

The utility model provides a tissue ligation clamp, which comprises an upper clamp arm 1 and a lower clamp arm 2, wherein the tail ends of the upper clamp arm 1 and the lower clamp arm 2 are fixedly connected, the front ends of the upper clamp arm 1 and the lower clamp arm 2 are mutually locked and fixed through a locking mechanism, the clamping surfaces of the upper clamp arm 1 and the lower clamp arm 2 are mutually matched wave-shaped curved surfaces 5, first anti-skid lines 6 are arranged on the wave-shaped curved surfaces 5, and the wave-shaped curved surfaces 5 and the first anti-skid lines 6 can increase the stress on tissues and improve the laminating degree of the tissues; a plurality of convex teeth 3 are arranged on the clamping surface of one of the upper clamping arm 1 and the lower clamping arm 2 along the length direction of the clamping arm, second anti-skid threads 7 are arranged on the convex teeth 3, and a plurality of tooth sockets 4 matched with the convex teeth 3 are arranged on the clamping surface of the other clamping arm along the length direction of the clamping arm; as preferred, protruding tooth 3 with alveolus 4 be in go up arm lock 1 with be equipped with 2 rows at least along length direction on the clamping face of lower arm lock 2, multirow protruding tooth 3 and alveolus 4 have further improved the utility model discloses to the compressive force of tissue, improved the ligature effect to the tissue.

the above description is only for the preferred embodiment of the present invention and is not intended to limit the scope of the present invention, and any modification and modification made by those skilled in the art according to the above disclosure are all within the scope of the claims.
