Embodiment 1

[0029] The human body soft tissue fixator in this example, such as figure 1 As shown, it is composed of a sheet-shaped support 1 and hook teeth 2 , and a plurality of hook teeth 2 are distributed and fixed on the support 1 . The support member 1 is butterfly-shaped, and is provided with circular and triangular through holes 3. The hook teeth 2 form an angle of 15 degrees with the plane of the support member 1. The height of the hook teeth 2 is 0.5mm, and the diameter of the hook teeth 2 is 0.5mm, the direction of the hook teeth at both ends is opposite, and the shape of the hook teeth is a cylindrical inclined tip shape. The edge of the support member 1 is a straight line, and there is an arc transition between the lines.

[0030] The support member 1 and the hook teeth 2 are made of biodegradable biomedical material, which is polylactide with an intrinsic viscosity of 0.5.

Embodiment 3

[0037] The human body soft tissue fixator in this example, such as image 3 As shown, it is composed of a sheet-shaped support 1 and hook teeth 2 , and a plurality of hook teeth 2 are distributed and fixed on the support 1 . The support 1 is in the shape of a strip, and a crescent-shaped through hole 3 is arranged on it. The hook teeth 2 form an angle of 30 degrees with the plane of the support 1. The height of the hook teeth 2 is 10 mm, and the diameter of the hook teeth 2 is 5 mm. The direction of the hook teeth is toward the same direction, and the shape of the hook teeth is a cylindrical inclined tip shape. One end edge of the support member 1 is a straight line, the other end and both side edges are curved lines, and there is an arc transition between the lines. One end of the support member 1 is provided with a reverse control strip 4 to facilitate operation.

[0038] The support member 1, the hook teeth 2 and the reverse control strip 4 are made of biodegradable biome...

Abstract

The invention belongs to the field of medical apparatus and instruments and relates to a human body soft tissue fixer which is characterized by comprising a sheet-shaped strutting piece (1) and gulletteeth (2). The gullet teeth (2) are distributed and fixed on the strutting piece (1); a through hole (3) is arranged on the strutting piece (2); an included angle formed by the gullet teeth (2) and the plane of the strutting piece (1) is 15-75 degrees; and the height and the diameter of each gullet tooth (2) are respectively 0.5-10 mm and 0.5-5 mm; the strutting piece (1) and the gullet teeth (2)are both made of degradable biomedical materials. Compared with the prior art, the invention can avoid suture cutting, prevent human soft tissues from necrosing, can be operated conveniently and biodegraded.

Description

Technical field: [0001] The invention belongs to the field of medical equipment, and in particular relates to a human body soft tissue fixer. Background technique: [0002] In human surgery and trauma medicine, soft tissue needs to be fixed, and the methods currently used are generally needle suture and adhesive bonding. [0003] Needle and thread sutures are the most widely used technique, using stainless steel needles of various shapes and silk threads to suture soft tissues. With the advancement of technology, new technologies such as absorbable sutures and non-traumatic suture needles have appeared, but the basic characteristics of the connection between tissues through point-to-point sutures have not changed. The characteristics of this technology are Convenience, reliable effect and low cost. But the problem that exists is: because after suturing with suture, generally will tie knot and fix with force, in this process, suture has the effect of cutting to soft tissue,...
