Problems solved by technology

However, due to the smooth and soft surface of the tendon, and the small surgical incision, the tendon is usually relatively thin, and manual tying of sutures and the use of tying aids are very time-consuming and laborious.
The lockable three-dimensional tendon stapler provided by the above-mentioned Chinese patent can only provide the auxiliary function of fixing the suture to the tendon stump, and the operation is still relatively complicated, and the positioning and docking of the tendon stump cannot be realized

Embodiment Construction

[0019] like figure 1 As shown, the tendon positioning anastomat of the present invention includes a left splint 1, a right splint 2, and a positioning mechanism arranged between the left splint 1 and the right splint 2. Made of material, its upper ends are fixedly connected together, and its lower ends are separated into jaws. Pressing with fingers from both sides of left splint 1 and right splint 2 to the inside can change the distance from the left splint 1 and right splint 2 lower ends. Wire slots 3 are provided at the lower ends of the left splint 1 and the right splint 2 . The two slots 3 on the left splint 1 and the right splint 2 are arranged coaxially, and their axes are parallel to the movement track of the splint when the left splint 1 and the right splint 2 are pressed.

[0020] like Figure 2-4 As shown, the trunking 3 is a groove-like structure with an arc-shaped cross section and variable curvature. It can be made of metal materials such as stainless steel shee...

Abstract

The invention relates to a medical surgical instrument, in particular to a muscle tendon locating anastomat. The muscle tendon locating anastomat comprises a pair of locating pincers composed of a left clamping plate, a right clamping plate and a locating mechanism, a wire groove is formed in the lower end of the locating pincers, a through hole and a crack which are specially formed are formed in the wire groove, a suture wire is mounted on the wire groove in an 8-shaped penetrating and inserting mode according to a certain sequence. During use, broken ends of a muscle tendon are placed in the wire groove, ends of the suture wire are tightened to tighten the broken ends of the muscle tendon, then, tighten ed broken ends of the muscle tendon are in butt joint together through the locating pincers, and the ends of two suture wire are bound. The muscle tendon locating anastomat is simple to operate, easy to master, high in binding standardization degree, high in anastomosis quality and low in degree of dependence on individual experience of an operator; and and the broken ends of the muscle tendon are free from puncture injury, firm in binding and free from tearing the muscle tendon.

Description

technical field [0001] The invention relates to a medical operation instrument, in particular to a tendon positioning stapler. Background technique [0002] The tendons of mammals, including humans, are composed of longitudinal fiber bundles, connected together by loose connective tissue between the bundles, and have strong longitudinal tensile strength, but weak transverse tear resistance. Tendon rupture and defect are mostly caused by injury or disease. In order to restore the function of limbs, the rupture or defect of tendon must be repaired in time. Tendon anastomosis is an operation in which a ruptured tendon is repaired and sutured to restore its function. Since the tendon is mainly composed of longitudinal fibers, the broken end is easy to split or be pulled by the suture during suture, and this kind of puncture suture is completely manual, which is very dependent on the individual experience of the operator just like manual sewing. It takes a long time of practice...
