Method and device for preparing medical sutures from tail tendons of beavers

Abstract

A method for preparing medical sutures from tail tendons of beavers mainly comprises steps as follows: extraction and processing of tail tendon tissue of the beavers, stretching and cleaning by the aid of a special tension device, preparation of sutures with needles, detection and packaging. The tension device comprises a base support, a motor, a belt pulley, a rotary drum, a rotary drum shaft, a bearing seat, a batten, an arc bristle brush mounting plate and bristle brushes. The method has the benefits as follows: 1, the prepared sutures have all-natural biological original nature; 2, the sutures are completely absorbed and do not have side effects; 3, tissue compatibility is good; 4, the sutures have smooth surfaces, yarn evenness, accurate suture diameter and ideal tension strength. With the adoption of one tension device, a large amount of tail tendon tissue of the beavers can be fixed, and the efficiency is high; besides, the tail tendon tissue of the beavers can be cleaned while the tail tendon tissue of the beavers is fixed and stretched to guarantee the tension strength, cleanliness and smoothness of a product are improved, and pain of a patient in surgical suturing is relieved.

Description

technical field [0001] The invention relates to the technical field of biomedicine, in particular to a method and a device for making absorbable medical suture from beaver tail tendon tissue. Background technique [0002] At present, known surgical operations mainly contain three basic operations of cutting, hemostasis and suturing, and medical sutures must be used during hemostasis and suturing. There are many types of sutures, which can be divided into two types according to their biodegradability. One is non-absorbable sutures, which do not degrade in the body and remain in the tissue as foreign bodies in the body if they are not removed by surgery; the other is absorbable sutures. The suture, which can degrade in the body into soluble products, usually disappears from the point of implantation after a month. The use of non-absorbable sutures to suture the epidermis, especially the facial skin, will leave scars on the skin. For the suturing of internal organs, the use of...

Problems solved by technology

But this method has the following problems: 1, chemical residues have toxic effects, which is not conducive to human health; 2, the tension strength is not enough to meet the needs

Moreover, the tension device used is generally a wire management frame. This device has the following defects in the actual production process: 1. The number of beaver tail tendon tissues that can be fixed by a wire management frame is limited, and enterprises need to use a large number of wire management frames. 2. A large number of wire management frames require a large area for drying, which has brought troubles to the enterprise due to insufficient space; 3. This wire management frame can only simply fix and stretch the tendon tissue of the beaver tail, while It cannot be cleaned, the smoothness of the tendon tissue in the beaver tail is not smooth enough, and the patient has a strong pain when suturing
