Abstract

The invention relates to a knee operation fixing device which comprises a foot fixing part and a locating frame. The foot fixing part comprises a shoe plate, a first sliding block and a bottom plate.The bottom of the shoe plate is spherically hinged to the first sliding block. The bottom plate is provided with a first sliding rail, and the first sliding block is mounted on the first sliding railin a sliding mode and can drive the shoe plate to move along the first sliding rail. A traction belt fixing lever is arranged on the front side of the first sliding block, a traction lever is arrangedat the front end of the first sliding rail, one end of the traction belt is connected with the first sliding block through the traction belt fixing lever, and the other end of the traction belt penetrates the traction lever downwards and is provided with a balance weight for fixing the knee. The locating frame comprises a connecting part, and connected with the bottom plate through the connectingpart, the locating frame is arranged on one side of the bottom plate, and the bottom plate is fixed to a frame to be mounted. The knee operation fixing device can replace a doctor to fix the foot andleg space positions of a patient, and the knee of the patient can be kept at different bending stretching degrees and enstrophe and ectropion angles for a long time.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a knee joint surgical fixation device. Background technique [0002] Knee joint surgery often needs to keep the patient's knee joint position fixed for a long time throughout the operation until the end of the operation. At present, most knee joint operations use manual fixation, which requires the cooperation of multiple doctors who are responsible for fixing the position of the patient's legs and feet and making adjustments as needed during the operation. This method increases the number of people involved in the operation, and the doctor who is responsible for fixing the position of the patient's leg maintains a posture for a long time, the work intensity is high, and muscle fatigue is prone to occur, which will have a great impact on the stability of the fixation, resulting in a greatly reduced surgical effect. . At the same time, there are many uncertainties in t...
