技术领域technical field
本发明属于医用器械的技术领域，具体涉及一种用于胫骨髓内钉手术的体位垫结构。The invention belongs to the technical field of medical instruments, and in particular relates to a body position pad structure for tibial intramedullary nail surgery.
背景技术Background technique
胫骨骨折是临床常见的创伤，闭合复位髓内钉内固定治疗胫骨骨折、尤其是胫骨干骨折是目前临床最为常用的方式。在整个手术治疗中，胫骨的闭合复位及髓内钉的插入固定是最为重要的手术步骤。在这复位及固定的过程中，膝关节须保持曲屈位，在这体位方能进行髓内钉的插入及调整，并且在完成置钉前，膝关节须保持曲屈位，以使得髓内钉的顺利插入及避免髌骨及膝前软组织的损伤。Tibial fracture is a common clinical trauma, and closed reduction and intramedullary nailing for the treatment of tibial fractures, especially tibial shaft fractures, are currently the most commonly used clinical methods. In the whole surgical treatment, the closed reduction of the tibia and the insertion and fixation of the intramedullary nail are the most important surgical steps. During this reduction and fixation process, the knee joint must be kept in a flexed and flexed position, and the intramedullary nail can be inserted and adjusted in this position. The smooth insertion of the nail and the avoidance of damage to the patella and the anterior soft tissue of the knee.
目前临床在该手术操作中，膝关节的曲屈体位一般有手术助手辅助完成，膝关节腘窝下垫入较多敷料，然后再曲屈膝关节，完成操作。但临床医师发现，这种膝下垫较多敷料、然后助手辅助曲屈固定膝关节的操作，出现较多不便：In the current clinical operation, the flexion and flexion of the knee joint is generally completed with the assistance of a surgical assistant, and more dressings are placed under the popliteal fossa of the knee joint, and then the knee joint is flexed to complete the operation. However, clinicians found that this kind of operation with more dressings under the knee, and then assistant-assisted flexion and fixation of the knee joint caused more inconveniences:
膝下垫入较多敷料，术中发现膝关节固定不牢靠、尤其髓内钉须用力旋入插入髓腔过程中，膝关节易出现上下左右漂移，经常需助手调整固定，这不但影响了手术的操作，还有可能导致髓内钉插入力线的偏移，影响手术的进程。More dressings are placed under the knee. During the operation, it is found that the fixation of the knee joint is not reliable, especially when the intramedullary nail must be forcefully screwed into the medullary cavity. The operation may also lead to the deviation of the insertion force line of the intramedullary nail, affecting the process of the operation.
使得助手相当费力，术中需有一专有组手需全程扶持固定膝关节，影响人力，增加手术成本。This makes the assistant quite laborious, and requires a dedicated set of hands to support and fix the knee joint throughout the operation, which affects manpower and increases the cost of the operation.
