Abstract

The invention relates to a fixing device, in particular to a tibia intercondylar spine fracture reduction fixing device. The invention provides the tibia intercondylar spine fracture reduction fixing device which can fix the legs of a patient, can assist in positioning the hollow sleeve and is more accurate and stable in surgical operation. The tibia intercondylar spine fracture reduction fixing device comprises a first connecting rod, clamping rings, a torsion spring and the like, the upper side and the lower side of the first connecting rod are each rotationally sleeved with a set of clamping rings, every two clamping rings form one set, the two clamping rings in the same set are symmetrically arranged in the front-back direction, and the two clamping rings in the front side and the rear side are symmetrically arranged in the front-back direction. A pull rod is connected between the two clamping rings on the same side, a torsional spring is connected between the clamping rings and the first connecting rod, and the torsional spring is wound around the outer side of the first connecting rod. The shank of a patient is clamped through the clamping ring during an operation, and the positioning ring has an auxiliary positioning effect on the hollow sleeve, so that the operation of the operation is more accurate and stable.

Description

technical field [0001] The invention relates to a fixation device, in particular to a reduction and fixation device for tibial intercondylar spine fracture. Background technique [0002] The tibial intercondylar spine fracture is an injury caused by the avulsion fracture of the anterior cruciate ligament of the knee joint. This type of injury is usually caused by strong excessive exercise and traffic accidents. For the non-displaced tibial intercondylar spine fracture , during treatment, it can usually be treated conservatively, and the lower limbs are immobilized with plaster for about 5-6 weeks, and regular X-ray examinations are required. For the obviously displaced tibial intercondylar ridge fracture, it needs to be treated with reduction surgery. For reduction surgery, it is necessary to incise the knee joint with minimally invasive surgery or fix it with an arthroscope. [0003] According to patent authorization publication number CN210962257U, a minimally invasive fi...
