Abstract

The invention discloses an orthopedic joint replacement surgery device. The orthopedic joint replacement surgery device comprises a bed board, wherein one side of the bed board is connected with a supporting table through a fixing bolt; guide rail grooves are symmetrically formed in the supporting table; sealing pipes are arranged in the guide rail grooves; piston blocks are slidably connected inthe sealing pipes; connecting rods are fixedly connected to the piston blocks; a plurality of permanent magnet sliding blocks are fixedly inserted into the connecting rods in a penetrating mode; the plurality of permanent magnet sliding blocks are arranged at equal intervals; a plurality of magnetic sliding sleeves are slidably connected to the sealing pipes in a sleeving mode; and the plurality of magnetic sliding sleeves correspond to the plurality of permanent magnet sliding blocks one by one. According to the orthopedic joint replacement surgery device, a piston plate slides up and down byrotating a current adjusting knob forwards and backwards, so that the magnetic sliding sleeves drive foot supporting pads to move leftwards and rightwards, after the adjustment is completed, only a valve needs to be closed, the current adjusting knob is rotated to enable an electromagnet to be powered off, then the angle of a joint can be maintained, the whole adjusting process is free of noise pollution, the reaction is rapid, and unnecessary operation idle time is saved.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to an orthopedic joint replacement operation device. Background technique [0002] The knee joint is an important weight-bearing joint of the lower limbs. Its structure and function are the most complex among human joints. Whether it is limited flexion or knee flexion contracture, it will hinder the operation to varying degrees. Restricted knee flexion will affect the exposure of the knee surgical field, positioning instruments cannot be placed correctly, the tibial plateau, the posterior femoral condyle will be cut, and the removal of osteophytes behind the knee joint capsule will become very difficult. Mild knee flexion contractures (less than 30 degrees) are very common. little impact on surgical operations. Severe knee contracture is more common in patients with rheumatoid arthritis, especially those who cannot walk for a long time and must be bedridden or rely on ...
