Description

Tendon half-taking-out guide

Technical Field

The present application relates to the field of medical devices, and in particular to a tendon half extraction guide.

Background

Tendon transfer is a technique in which when a group or a muscle is reduced or lost due to various causes, tendons adjacent to healthy muscles are transferred to the reduced or lost position, and the reduced or lost muscles are restored to prevent deformity.

In the tendon transfer operation, in order to recover the muscle with reduced or lost function, the transplanted muscle has a good function, and generally, one half of the tendon can be transplanted during the transplantation, i.e. the tendon is cut along the width direction of the tendon, so that the transplanted tendon and the transplanted tendon are both one half of the width of the whole tendon.

Referring to fig. 1, a tool used for transplanting half of the tendon is a vascular clamp 44, during operation, a first incision 41 is cut at the epidermis at one end of the tendon to be transplanted, then scissors are penetrated through the first incision 41 and cut on the side wall of the tendon, the cutting length is half of the width direction of the tendon, so that the half of the tendon after cutting can be separated from the tendon as a whole, and the cutting position of the scissors is the beginning end 42 of the tendon to be transplanted; then, a second incision 43 is cut on the epidermis at the other end of the tendon to be transplanted, and a vascular clamp 44 is inserted between the epidermis and the tendon from the second incision 43, and the vascular clamp 44 is operated to move to the beginning end 42 of the tendon to be transplanted along the length direction of the tendon, and the beginning end 42 of the tendon to be transplanted is clamped by operating the vascular clamp 44; finally, the vascular clamp 44 is pulled by the staff outside until the vascular clamp 44 is pulled out, at this time, the tendon to be transplanted is also pulled out, and the staff directly cuts off the tendon to be transplanted when the length is proper, so that the tendon to be transplanted can be taken out.

However, since the vascular forceps comprise two mounting rods with the middle parts hinged in an X shape, and the vascular forceps need to have certain strength so that the vascular forceps can clamp and fix transplanted tendons, the diameter of the vascular forceps has certain requirements and cannot be too thin, and the whole occupied space of the two mounting rods is increased. Therefore, when the second incision for inserting the blood supply forceps is formed, the formed second incision is also relatively large, and simultaneously, when the blood supply forceps is opened to clamp the transplanted tendon, the two mounting rods are far away from each other, so that the patient is also subjected to abrasion damage, and the injury to the patient is relatively large.
