Description

Meniscus anterior horn sword

Technical Field

The utility model relates to an orthopedics medical instrument field, concretely relates to anterior horn sword of meniscus.

Background

Discoid meniscus deformity or anterior horn injury is a common disease in the department of sports medicine, and is always a hot spot concerned by wide students about the postoperative clinical effect. The arthroscopic discal meniscus operation is a common operation for clinically treating patients with knee joint discal meniscus injury at present, can reserve the meniscus structure and functions to the maximum extent, further protect the knee joint cartilage and delay the development of knee osteoarthritis.

With the rapid development of medical industry, arthroscopy technology has the advantages of small wound, high safety, few complications, light pain degree and the like, and is widely applied to orthopedics clinic. Meniscus injury has become the most common disease in orthopedic sports medicine in recent years, wherein the arthroscopic meniscal arthroplasty repair is the most surgical method in the current orthopedic arthroscopic surgery. The technology has the advantages that the meniscus in the knee joint can be directly observed and operated by utilizing a tiny incision, then the lesion is specifically treated, the wound is small, the complication is few, and the like, so the technology is generally accepted by specialists and patients.

Arthroscopic knee surgery has been known for many years, and surgeons have become more sophisticated, and the arthroscopic knee instruments are also widely varied and have improved considerably over the prior art. However, for a patient with disc-shaped meniscus or meniscus anterior angle injury at present, the anterior angle of the meniscus is difficult to observe and operate by using a conventional arthroscopic approach and common instruments, at present, clinicians mostly use a scalpel to perform shaping repair on the anterior angle of the disc-shaped meniscus from a contralateral standard arthroscopic approach, but the tip of the scalpel is easy to scratch cartilage, too long blades are also easy to injure skin incisions and cruciate ligaments, and the normal meniscus form is difficult to repair, and the operation difficulty is large due to the angle problem and the shape of the scalpel.

SUMMERY OF THE UTILITY MODEL

In order to solve the problem, the utility model discloses a meniscus anterior angle sword, this meniscus anterior angle sword can effectively protect knee joint cartilage when taking shape or excising damaged meniscus anterior angle to disc meniscus or meniscus anterior angle injury patient anterior angle, avoids the injury of scalpel blade cutting edge to articular cartilage and soft tissue, still can collude the half meniscus anterior angle of clamp simultaneously, and stable accuracy is amputated and is taken shape to disc half meniscus anterior angle, and is more simple and easy in the operation.

In order to achieve the technical effects, the utility model discloses a following technical scheme realizes:

the utility model provides a meniscus anterior horn sword, including the operation sleeve, the front end of operation sleeve is fixed with U type double track hook, it has the push handle sliding tray to open at operation sleeve's top, the operation sleeve is opened along the axis direction has operation channel, it has link up with operation channel to push handle sliding tray, be provided with in the push handle sliding tray and push away the handle, be provided with the trace axle among the operation channel, it is articulated with the trace axle that the push handle passes through the trace, the operation sleeve is stretched out at the both ends of trace axle, the front end of trace axle is fixed with meniscus anterior horn shovel, the rear end of trace axle is fixed with the handle of gripping, the width of meniscus anterior horn shovel is greater than the width of U type double track hook.

Preferably, the linkage shaft is fixedly connected with the meniscus front angle shovel through an arc-shaped bent section.

Preferably, the push handle is hinged with the linkage shaft through a pair of linkage rods arranged in a shape like a Chinese character 'ba', two grooves are formed in the linkage shaft, clamping rings are fixed at the end parts of the linkage rods and clamped in the grooves of the linkage shaft.

The utility model has the advantages that: the U-shaped double-track hook can hook the front angle of the disc-shaped meniscus, so that the front angle of the meniscus can be conveniently and accurately cut off by the front angle shovel of the meniscus, and the front angle shovel of the meniscus can be limited, so that the front angle shovel of the meniscus is prevented from exceeding the cutting range, and the articular cartilage is prevented from being damaged; the device is simple to operate, safe and effective, has low cost, meets the operational requirement of the knee arthroscope on meniscus forming, and has good practical value.
