Knee arthroscope operation stent

Abstract

The invention discloses a knee arthroscope operation stent, which comprises a stent body fixedly connected with an operation table, a rotating disc I fixedly arranged on the stent body, a connecting rod I, a rotating disc II and a connecting rod IV. A locating hole I is arranged at the edge of the rotating disc I, one end of the connecting rod I is hinged to the center of the rotating disc I, a location pin I is arranged on the connecting rod I, and a connecting rod II is fixedly arranged at the other end of the connecting rod I. The rotating disc II is arranged perpendicular to the rotating disc I, a far end of the connecting rod II is hinged to the center of the rotating disc II, a locating hole II is arranged at the edge of the rotating disc II, and a location pin II matched with the locating hole II is arranged on the connecting rod II. A connecting rod III is fixedly arranged on the rotating disc II, one end of the connecting rod IV is hinged to a far end of the connecting rod III, and a fixing sleeve used for fixing ankles is arranged at the other end of the connecting rod IV. Angles at various directions can be adjusted and continuously fixed by the knee arthroscope operation stent according to operation requirements, a continuously stable and reliable operation environment can be provided for medical personnel, operation quality is guaranteed, manpower resources are saved, efficiency is improved, and the knee arthroscope operation stent is simple in structure, convenient to use and easy to manufacture.

Description

technical field [0001] The invention relates to a medical auxiliary device, in particular to a support for knee arthroscopic surgery. Background technique [0002] The knee joint is one of the most vulnerable joints in the human body. When the knee joint moves, there is contact and extrusion between the femur, tibia and patella. Trauma, infection, strain, deformity or degenerative changes can easily cause knee joint lesions, such as anterior cruciate ligament injury, posterior cruciate ligament injury, joint Internal fractures, meniscal injuries and suppurative knee arthritis, rheumatoid arthritis, lateral subluxation of the patella, loose bodies of the knee joint, etc. When conservative treatment fails, surgery becomes an important way to solve knee joint pain and dysfunction. [0003] With the development of minimally invasive surgery, arthroscopic surgery has become one of the preferred treatment methods for the above-mentioned many knee joint injuries, and has been wid...

AI Technical Summary

Problems solved by technology

At present, during the whole operation, the patient's knee joint flexion and extension and the adjustment of valgus and valgus angle are all completed by the assistant (or the surgeon himself), that is, the patient's limb is moved and maintained at a specific position by manpower, and adjusted at any time according to the operation needs. The staff has high work intensity and high physical exertion. Affected by the patient's body shape and the degree of knee joint disease, the affected limb is not easy to maintain stability, and the assistant's understanding of the operation, technical level, and the degree of cooperation with the operator will affect the operation of the patient. The proper degree of knee position affects the smooth implementation of the operation
