Problems solved by technology
[0003] The old technique is extremely complicated and has narrow indications. It can only be stretched between the intercondylar fossa and the intercondylar eminence. It is mainly used for arthroscopic repair of the posterior angle of the meniscus in the knee joint. Most injuries to the posterior angle of the meniscus In some patients, the joint bundle contracture makes it difficult to expose the posterior angle of the meniscus, and the operation time is long, which increases the local damage

Abstract
The invention discloses a knee arthroscopic joint distraction apparatus which structurally comprises a joint distraction apparatus body, distraction apparatus arms, finger fasteners, reverse distraction end spikes, work ports, a connecting hinge pin and a latch. The finger fasteners are arranged on two sides of the bottom of the joint distraction apparatus body, the distraction apparatus arms aredistributed on two sides of the top of the joint distraction apparatus body, the connecting hinge pin is arranged in the middle of the joint distraction apparatus body, first arc-shaped sawteeth are welded at the bottom of the right of the joint distraction apparatus body, the latch is welded at the bottom of the left of the joint distraction apparatus body and is connected with the first arc-shaped sawteeth by tooth fasteners, the work ports are arranged on the tops of the distraction apparatus arms, and the reverse distraction end spikes are welded on two sides of the distraction apparatus arms. The knee arthroscopic joint distraction apparatus has the advantages that the knee arthroscopic joint distraction apparatus is novel and reasonable in design, wide in service range, convenient tooperate, short in surgical time and little in injury, good distraction effects can be realized by the knee arthroscopic joint distraction apparatus, surgical operation can be greatly facilitated, thesurgical speeds can be obviously increased, and the surgical quality can be obviously improved.
Description
technical field [0001] The invention relates to the technical field of orthopedic surgical instruments and equipment, in particular to a knee arthroscopic arthroscopic spreader. Background technique [0002] Knee arthroscopy can inspect, diagnose and treat intra-articular diseases, and is suitable for knee joint injuries and non-infectious arthritis. Currently, knee arthroscopy is considered to be a better treatment for knee joint lesions. Traditional knee surgery involves large trauma, heavy bleeding, slow postoperative recovery, and large surgical scars on the joints. In contrast, arthroscopic knee surgery has the advantages of less trauma, less bleeding, exact curative effect, faster recovery, and fewer complications. Less and less surgical scar and other advantages. [0003] The old technique is extremely complicated and has narrow indications. It can only be stretched between the intercondylar fossa and the intercondylar eminence. It is mainly used for arthroscopic rep...
