The utility model discloses a knee valgus auxiliary operation position frame, which comprises a base, a control board, a power supply, a switch, a torsion seat, a torsion bar, an L-shaped plate and an L-shaped plate, a fixed plate fixed connected with the operation bed position frame and a clamping slot fixed with a torsion seat, and a torque sensor at the bottom of the clamping slot. The board is equipped with a single-chip microcomputer and an alarm device; the power supply and the control board are fixed in a fixed board; the switch is fixed in a fixed board; the power supply and the torque sensor are connected with the control board electrically; the alarm device is controlled by a single-chip microcomputer; the switch is set between the power supply and the control board; the torsion seat and the torque sensor are fixed in a fixed connection The top of the torsion seat is provided with a groove; the torsion bar is Z-shaped; one end of the torsion bar is fixed and connected with the torsion seat; the L-shaped plate is fixed in the groove; the L-shaped plate is fixed and connected with the operation bed position frame. The above scheme can effectively expand the medial space of the knee joint, expose the posterior horn of the medial meniscus, and limit the maximum valgus torque in the process of valgus knee joint to avoid iatrogenic injury caused by excessive valgus.

膝关节外翻辅助手术体位架
本技术涉及膝关节外手术辅助装置的
,尤其涉及一种膝关节外翻辅助手术体位架。
技术介绍
膝关节半月板为纤维软骨组织,呈周缘厚,内缘薄的楔形,从平面上看为半月形,称为半月板;其充填于股骨髁与胫骨髁之间,有增强膝关节稳定的作用。半月板结构和功能的特点决定了它是膝关节内最易损伤的组织之一。半月板撕裂是体育运动中非常常见的一种运动创伤,往往由于关节活动的不协调,如踢球时踢空、对脚,或跑动中被绊倒等膝关节扭伤时,导致半月板卡在股骨和胫骨间,引起撕裂。如果同时存在其它情况,如长期处于蹲位劳动、原来有过韧带损伤、原来有盘状半月板等,则更容易引起撕裂。老年人由于半月板有退变老化,也很容易引起撕裂。而这些撕裂的引起甚至可以没有明显的外伤。半月板撕裂是目前运动医学最常见疾病,其中以内侧半月板后角损伤最为多见。目前应用关节镜手术能在微创的情况下很好地治疗半月板撕裂,但是内侧半月板后角的暴露较为困难,尤其是在合并膝关节退变引起内侧间隙狭窄的病例中。在内侧半月板后角的暴露困难时,目前没有适合的、性价比高的辅助体位架来辅助扩大膝关节内侧间隙,需要借助于手术助手维 ...
