Force line calibration fixing device

Abstract

The invention relates to the technical field of medical instrument design, in particular to a force line calibration fixing device. The force line calibration fixing device comprises a foot force line fixing device, a waist force line fixing device and a force line rod, the foot force line fixing device comprises a bottom plate, a vertical frame and an angle plate, a connecting block is fixedly installed at the top of the vertical frame, a plurality of fixing rods are installed on the angle plate, a first connecting rod is installed on the connecting block, a first transition block is fixedly installed on the first connecting rod, a second connecting rod penetrates through the first transition block, a second transition block is fixedly installed on the second connecting rod, a third connecting rod penetrates through the second transition block, a first force line rod fixing block is installed on the third connecting rod, the waist force line fixing device comprises a cross rod, a vertical rod and an angle adjusting rod, one end of the angle adjusting rod is connected with the cross rod, the other end of the angle adjusting rod is fixedly provided with a second force line rod fixing block, and a force line rod is inserted between the first force line rod fixing block and the second force line rod fixing block. According to the instrument, the feet of a patient can be firmly fixed, and the measured force line angle is accurate.

Description

technical field [0001] The invention relates to the technical field of medical device design, in particular to a force line calibration and fixing device. Background technique [0002] The reason for the symptoms of valgus deformity of the knee joint is due to the transfer of the weight-bearing force of the lower limbs and the local high stress. For young patients or patients with high willingness to move, osteotomy around the knee joint and "knee-preserving" treatment are more and more popular. Pay attention; Osteotomy around the knee joint and fixation through medial and lateral tibial or medial and lateral femoral osteotomy can correct the abnormal force line from the coronal plane, and the treatment effect is obvious. The calibration of the force line in the operation is very important. Using the common force line calibrator, intraoperative movement often occurs, or the patient moves unconsciously, and the position of the force line rod changes, which affects the intraop...

Problems solved by technology

The calibration of the force line in the operation is very important. Using the common force line calibrator, intraoperative movement often occurs, or the patient moves unconsciously, and the position of the force line rod changes, which affects the intraoperative calibration and causes the force line to be calibrated incorrectly. Causes the failure of alignment correction, which affects the surgical effect; at the same time, common alignment devices require doctors to be exposed to X-rays during the operation, which can easily have adverse effects on the body
