Knee arthroscope joint spreader for orthopedics departments

Abstract

The invention discloses a knee arthroscope joint spreader for orthopedics departments. The knee arthroscope joint spreader comprises grab handles, a tightening lock catch and sharp spreading thorns. The tightening lock catch is arranged on the side walls of the grab handles. The spreading thorns arranged at the tops of the grab handles are fixedly connected with the grab handles. The grab handlesinclude a left grab handle and a right grab handle. The left grab handle is rotationally connected with the right grab handle. A rotating and sliding device is arranged in the middles of the left grabhandle and the right grab handle. A leaf spring is arranged on the inner side of the left grab handle. The tightening lock catch comprises a locking strip and a locking buckle. The locking strip is fixedly connected with the right grab handle. The locking buckle is movably connected with the left grab handle. Sharp tips are arranged at the tops of the sharp spreading thorns. The sharp spreading thorns are fixed to the tops of the grab handles reversely. The knee arthroscope joint spreader can be directly spread between femoral condyle and tibial plateau, injury exacerbation is avoided, and spreading can be achieved; the design is novel and reasonable, the application range is wide, convenience in operation and good spreading effect are achieved, surgery time is short, and injury is small.

Description

technical field [0001] The invention relates to the technical field of orthopedic surgical instruments, in particular to an orthopedic knee arthroscopic arthroscopic spreader. Background technique [0002] In the arthroscopic repair of knee articular cartilage without damage but meniscus posterior horn damage, there are more patients with meniscus posterior horn injury with joint fascicle contracture, difficult exposure of the meniscus posterior horn, and operation time It is long, difficult to operate, and increases local damage. The old technology is extremely complicated and has narrow indications, and can only be stretched between the intercondylar notch and the intercondylar eminence. The distraction effect is poor, the damage to the patient is relatively large, and the operation is inconvenient, which reduces the work efficiency of the doctor. Contents of the invention [0003] The purpose of the present invention is to provide an orthopedic arthroscopic arthroscopi...
