Description

Achilles tendon operation anastomosis forceps

Technical Field

The utility model relates to the technical field of medical equipment, especially, relate to an achilles tendon operation identical pincers.

Background

The medical apparatus refers to instruments, equipment, appliances, in-vitro diagnostic reagents and calibrators, materials and other similar or related articles directly or indirectly applied to the human body, and comprises required computer software, wherein the effects are mainly obtained in a physical mode and other modes, not in a pharmacological, immunological or metabolic mode, or are only assisted by the modes, so that the diagnosis, prevention, monitoring, treatment or alleviation of diseases are achieved; diagnosis, monitoring, treatment, mitigation, or functional compensation of injury; examination, replacement, regulation or support of a physiological structure or physiological process; support or maintenance of life; controlling pregnancy; by examining a sample from a human body, information is provided for medical or diagnostic purposes.

The achilles tendon is the toughest tendon of the human body and is one of the most fractured tendons of the human body, and foreign related researches show that the incidence rate of acute achilles tendon fracture is increased from 26.95/10 ten thousand in 1994 to 31.17/10 ten thousand in 2013, and the tendencies of acute achilles tendon fracture are increasing. Most of achilles tendon rupture treatments are incision operations at present, but the traditional incision operation mode has large trauma and is often accompanied with various postoperative complications such as incision edge necrosis, incision cracking, scar hyperplasia, tendon adhesion, infection, sural nerve injury and the like. In view of various complications of open surgery, the development of a minimally invasive technology has obvious advantages in repairing the rupture of the fresh achilles tendon, and in recent years, foreign scholars adopt an achilles tendon dragon anastomat to treat patients with the rupture of the fresh achilles tendon in a minimally invasive mode, so that a satisfactory effect is achieved, postoperative complications are reduced, and the peroneal nerve injury rate is high due to the suture mode. A channel-assisted minimally invasive Achilles tendon suturing system (CAMIR) is invented by Chenhua professor in the general hospital of the liberation military in 2017, and the system blocks the sural nerve outside a suturing channel by establishing the suturing channel, so that the sural nerve is effectively prevented from being damaged during suturing. However, the minimally invasive achilles tendon suture system assisted by the channel needs a special disposable suture guide, is expensive, cannot be used for medical insurance reimbursement, is complex to operate, and is difficult to widely develop the technology in hospitals or primary hospitals which cannot introduce the suture system, so that the achilles tendon surgical anastomosis forceps which are simple to operate, can be repeatedly applied and are low in cost are urgently needed to be researched.
