Support frame for knee joint surgery

Abstract

The invention discloses a support frame for knee joint surgery, comprising a bottom plate, a lifting bar arranged on the bottom plate and an arc plate arranged at the top of the lifting bar; the lifting bar comprises a main screw and a threaded sleeve which are in threaded connection, the main screw is connected to the bottom plate, the arc plate is connected to the top of the threaded sleeve, a front carrier plate and a rear carrier plate are hinged respectively to the front and rear of the arc plate through spindles, the part of the outer wall of the threaded sleeve close to its bottom is provided with a support plate, a vertically arranged adjusting screw is arranged on the support plate and is rotationally connected with the support plate, a slider is also included, the threaded sleeve is passed through the slider and slidably connected to the same, the adjusting screw is passed through the slider and in threaded connection with the same, and the front carrier plate and the rear carrier plate are connected to the slider respectively through obliquely arranged support rods. The support frame with such structure can keep suitable height and suitable flexion position for a knee joint, and therefore, operation is facilitated for surgeons, manpower resource consumption is recued greatly, and unnecessary damage is avoided.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a support frame for knee joint surgery. Background technique [0002] The current knee joint surgery, especially arthroscopic surgery, minimally invasive needle endoscopic surgery, and knee joint cavity puncture often requires the knee joint to be kept in a flexed position. During the operation, an assistant must always lift the thigh of the affected limb to maintain the knee. The joint is flexed or the knee joint is fixed, and the body position needs to be changed constantly. If the operation time is too long, the assistant will be very tired, which will affect the operation, and even the instrument may break in the knee joint. [0003] Therefore, there is an urgent need for a support frame for knee joint surgery, so that the knee joint can maintain a suitable height and a suitable flexion position, thereby facilitating the operator's operation, greatly reducing human resource...
