Recycling achilles tendon minimally invasive suturing apparatus and novel suturing manner thereof

Abstract

The invention discloses a recycling achilles tendon suturing apparatus and a novel suturing manner thereof. The recycling achilles tendon suturing apparatus comprises an outer side arm, a needle penetrating sleeve, a medical cutting cone, a dual-head needle with a suture line, a suturing needle guiding pipe, single-side forceps bodies of oval forceps, and a reverse meshing part, wherein the outerside arm and the single-side forceps bodies of oval forceps are mutually hinged together; the reverse meshing part is mounted at the upper part of the handle part of the oval forceps; the direction ofthe outer side wall is consistent with that of the front end of the oval forceps, and an inclined angle of 20 degrees is formed between the outer side wall and the handle part of the oval forceps inthe longitudinal axis direction; oval holes for fixing the needle penetrating sleeve are symmetrically formed in the same positions of the front parts of two side arms; and the medical cutting cone can penetrate through the oval needle penetrating sleeve of which the cross section is provided with a rhombus through hole to suture the breaking end of the achilles tendon through cooperating with a "rotation crossing" suturing method. The adopted suturing manner disclosed by the invention has the advantages of being small in wound, low in tissue damage, low in bleeding, and capable of effectivelypreventing partiality of sagittal suturing; and the whole apparatus is convenient to sterilize, low in cost, easy and convenient to operate, early-stage functional training of a patient and popularization of basic medical institutions are facilitated, and the whole apparatus has potential industrialization prospects.

Description

technical field [0001] The invention relates to the field of surgical instruments and methods, in particular to a novel recyclable minimally invasive suture instrument for Achilles tendon rupture and its suture method. Background technique [0002] The Achilles tendon is the thickest and most powerful tendon in the human body. It is about 15cm long. It is located behind the lower leg and connects the calf triceps and the calcaneus. Its main function is to be responsible for the plantar flexion of the ankle joint. The completion of such movements plays an important role. Achilles tendon rupture is usually caused by sports injuries or knife wounds. After the Achilles tendon rupture, the patient's walking function will be seriously affected. Acute Achilles tendon rupture is common in sports, and its incidence has been increasing in recent years, which is related to the increasing interest and participation in physical exercise, resulting in chronic strain of Achilles tendon; it...

AI Technical Summary

Problems solved by technology

In general, the technical features of the existing Achilles tendon suturing device include: 1. The main frame has no curvature or the curvature does not conform to the shape of the human body, so it is difficult to locate accurately under minimally invasive conditions; 2. It is divided into multiple parts and assembled It needs to be reassembled before the operation, which is complicated and time-consuming, and the parts are easy to be lost, and the cost is high

3. The pinhole design is simple, and the suture method is too single, resulting in insufficient suture strength; because the Achilles tendon belongs to the cord-like ligament tissue and the broken end is mostly in the shape of a horsetail, if the suture strength is insufficient, the rate of Achilles tendon re-rupture is high

The Achilles tendon suturing device achieves small incisions to complete the Achilles tendon suture, but because the matching Achilles tendon suture method has not been substantially improved, complications such as Achilles tendon re-rupture or Achilles tendon prolongation are prone to occur during the postoperative rehabilitation period , and because of the material, it is designed as a disposable device, which is expensive and increases the medical burden of patients
