Background
In the artificial joint replacement surgery, a file is often required to perform medullary cavity shaping, so that an instrument for holding the file needs to have the functions of holding the file, expanding the medullary cavity and taking out the file. At present, file holders commonly used in the medical market are all in a straight rod structure, and can well meet the requirement of common hip joint operations. However, in the minimally invasive hip joint replacement, because the surgical incision is small, generally 10cm, and the surgical incision enters through the muscle gap, when the file holder is connected with the file to mold the medullary cavity, severe muscle shielding exists, soft tissue contusion is easily caused, even the direction of the file is not consistent with the medullary cavity due to shielding, and secondary fracture of the femur, such as large tuberosity fracture, distal femur fracture and the like, is caused in the knocking process.
In order to solve the above problems caused by the straight rod structure in the prior art, a general operator can increase an operation incision or use an opening device to open soft tissues such as muscles as much as possible, so that the operation field is increased. However, the requirement of minimally invasive surgery is violated by increasing the incision, the operation space is enlarged by using soft tissue distraction devices such as surface distractors and draw hooks, and the soft tissue is damaged by over-pressing of the distraction instruments. When the medullary cavity is insufficiently molded, the stability of the installed prosthesis is influenced, and the advantages of micro trauma of minimally invasive surgery and postoperative satisfaction of patients are reduced.
Therefore, a minimally invasive hip replacement surgery file holding instrument for solving the problem of soft tissue shielding instruments in minimally invasive surgery is urgently needed.
