Knee joint surgical body position variable fixing apparatus

Abstract

The invention relates to a knee joint surgical body position variable fixing apparatus. The knee joint surgical body position variable fixing apparatus comprises a supporting platform, at least one transverse guide rail distributed in an axis-Y direction, at least one longitudinal guide rail distributed in an axis-X direction and a first slide block installed on the longitudinal guide rail, wherein the first slide block is provided with a first fastening element for locking the first slide block onto the longitudinal guide rail, the transverse guide rail is fixed on the supporting platform, the longitudinal guide rail is fixedly connected with a second slide block, the longitudinal guide rail is installed on the transverse guide rail by virtue of the second slide block, the second slide block is provided with a second fastening element for locking the second slide block onto the transverse guide rail, the first slide block is hinged to a transverse swinging seat by virtue of a first hinged shaft which is distributed in the axis-X direction, and the transverse swinging seat is hinged to a longitudinal swinging block by virtue of a second hinged shaft which is distributed in the Y-axis direction. By adopting the knee joint surgical variable body position fixing apparatus, the position of a knee joint can be sterilely adjusted by a surgeon during the surgical operation; and moreover, the knee joint surgical body position variable fixing apparatus is simple in operation, convenient to install and capable of being widely popularized and applied clinically.

Description

technical field [0001] The invention relates to a body position fixation device for knee joint surgery. Background technique [0002] In actual clinical work, the implementation of knee joint surgery requires the knee joint to be constantly changed between the extended position and the flexed position, as well as between internal rotation, non-rotation and external rotation. required posture. Maintaining the position for a long time will greatly consume the physical strength of the assistant and make the fixation unstable, which will affect the accuracy of the operation, the safety and reliability of the operation. Moreover, the existing fixation device is relatively heavy, complicated to install, and cumbersome to operate, which is not conducive to the operator's intraoperative adjustment and fixation, so it has not been widely used in clinical practice. Contents of the invention [0003] The invention solves the disadvantages of the prior art and provides a knee joint ...
