本发明属于医疗技术领域，具体涉及一种医用缝合器。The invention belongs to the field of medical technology, in particular to a medical stapler.
背景技术Background technique
手术切口和外伤导致的伤口都需要缝合，临床上广泛使用缝合针和持针器，缝合针是由针体和针眼组成，医护人员使用时先将线由针眼内穿入，再用持针器钳夹针体进行缝合，针体不易穿刺皮肤，再加上持针器重量较重，使用费力，且由于持针器与针体成一定角度，在缝合时容易使作用力不对称而导致针体弯曲甚至折断，而且有时持针器夹持不稳定，容易打滑甚至脱落造成医疗事故，缝合时有时需要多次换线，换线较为麻烦，现在尚未有任何一种缝合器械能解决以上问题。Surgical incisions and wounds caused by trauma need to be sutured. Suture needles and needle holders are widely used clinically. Suture needles are composed of a needle body and a needle eye. Clamp the needle body for suture, the needle body is not easy to pierce the skin, plus the weight of the needle holder is heavy, it is laborious to use, and because the needle holder and the needle body form a certain angle, it is easy to make the force asymmetric during suturing and cause the needle The body is bent or even broken, and sometimes the needle holder is unstable in clamping, easy to slip or even fall off, causing medical accidents. Sometimes it is necessary to change the thread many times during suturing, which is troublesome. There is no suturing instrument that can solve the above problems.
