技术领域Technical field
本发明涉及骨科手术器械技术领域，具体而言，涉及一种髌骨拉钩。The present invention relates to the technical field of orthopedic surgical instruments, and specifically to a patella retractor.
背景技术Background technique
在骨科手术过程中，良好的术野暴露是手术操作的关键。现有的髌骨拉钩在全膝关节置换术中使用较为便捷，通过将髌骨拉钩放置于胫骨平台的外侧边缘，使伸膝装置与股骨外侧髁拉拽分离，从而实现膝关节外侧结构的暴露。During orthopedic surgery, good exposure of the surgical field is the key to surgical operation. The existing patellar retractor is more convenient to use during total knee replacement. By placing the patellar retractor on the lateral edge of the tibial platform, the knee extension device is pulled apart from the lateral femoral condyle, thereby exposing the lateral structures of the knee joint.
在单髁关节置换术中，需要观察股骨外侧髁的软骨面的情况，决定继续进行单髁置换或者改为全膝置换，而在单髁关节置换术中，切口狭小并位于髌骨内侧，胫骨平台的外侧边缘无法暴露，无法像全膝关节置换术中那样放置现有的髌骨拉钩，导致将伸膝装置与股骨外侧髁拉拽分离的操作困难。In unicondylar joint replacement, it is necessary to observe the condition of the cartilage surface of the lateral femoral condyle before deciding to continue with unicondylar replacement or change to total knee replacement. In unicondylar joint replacement, the incision is narrow and located on the medial side of the patella and the tibial plateau. The lateral edge of the knee joint cannot be exposed, and the existing patellar retractor cannot be placed as in total knee replacement, making it difficult to pull and separate the knee extensor device from the lateral femoral condyle.
具体而言，如果将现有的髌骨拉钩的尖端放置在股骨外侧髁的外侧面强行拉拽使伸膝装置与股骨外侧髁分离，髌骨拉钩容易与髌骨的关节面碰触从而损伤髌骨的关节面，因此，在单髁关节置换术中使用现有的髌骨拉钩，无法满足对髌骨的关节面的保护要求。Specifically, if the tip of the existing patellar retractor is placed on the lateral surface of the lateral femoral condyle and is forcibly pulled to separate the knee extension device from the lateral femoral condyle, the patellar retractor will easily contact the articular surface of the patella and damage the articular surface of the patella. , therefore, using the existing patellar retractor in unicondylar joint replacement cannot meet the requirements for protecting the articular surface of the patella.
