Auxiliary limiting device for knee joint operation

Abstract

The invention discloses an auxiliary limiting device for a knee joint operation, and belongs to the technical field of medical instruments. The device comprises a thigh fixing clamping plate (1), a shank fixing clamping plate (4), a flexion and extension adjusting device (12) and a turning adjusting device (13). The flexion and extension adjusting device is composed of a flexion and extension adjusting nut (8), a large clamping plate connecting piece shaft sleeve (9), an adjusting shaft (10) and a small clamping plate connecting piece shaft sleeve (11). The turning adjusting device (13) is composed of a screw (5) and a turning adjusting nut (6). The thigh fixing clamping plate (1) is connected with the large clamping plate connecting piece shaft sleeve (9) of the flexion and extension adjusting device (12) through a large clamping plate connecting piece (3). The turning adjusting device (13) is connected with the small clamping plate connecting piece shaft sleeve (11) of the flexion and extension adjusting device (12) through a small clamping plate connecting piece (7). The auxiliary limiting device has the advantages of being simple in structure, convenient to operate, capable of saving operation time and adjusting the flexion and extension and inward and outward turning angles of the knee joints and the like.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to an auxiliary limiting device for hospital orthopedic knee joint surgery. Background technique [0002] In knee joint surgery, doctors always require patients to passively fix the legs in different positions. Since there is no special auxiliary tool in the prior art to fix the knee joint in an ideal position, 1-2 assistants are needed during the operation The doctor is responsible for immobilizing the affected limb, and the assistant doctor will put the patient's lower leg into the required posture according to the operation requirements and maintain this posture until the end of the operation. This will not only increase the cost of the operation and increase the economic burden on the patient, but also the doctor in charge of the fixation will be prone to fatigue if he maintains the same posture for a long time. Errors, surgical operations need to be repeate...

AI Technical Summary

Problems solved by technology

This will not only increase the cost of the operation and increase the economic burden on the patient, but also the doctor in charge of the fixation will be prone to fatigue if he maintains the same posture for a long time. error, the operation needs to be repeated

On the other hand, the assistant physician who is in charge of fixing often needs to be close to the patient, especially the part that needs to be operated on, which will also prevent the surgeon in charge from operating the surgical instrument, which will bring a lot of inconvenience to the operation
