Description

Thighbone near-end kirschner wire drilling location and many needles drilling auxiliary device
Technical Field
The invention relates to the technical field of medical auxiliary equipment, in particular to a proximal femur kirschner wire drilling positioning and multi-wire drilling auxiliary device.
Background
The femur (femur) is the longest tubular bone of the human body, and the upper end of the femur (femur) forms a hip joint with the acetabulum and the lower end of the femur (femur) forms a knee joint with the patella and the upper end of the tibia, and is used for supporting the weight of the whole body. The femoral neck and the femoral shaft have two important angle relationships, and on the coronal plane, the neck trunk axes are intersected to form a neck trunk angle; on the horizontal plane, the axis of the tibial neck and the transverse axis of the medial and lateral femoral condyles form an anteversion angle. The cervical shaft angle makes the femoral shaft offset to the outer side of the pelvis to adapt to the requirement of large-amplitude movement of the hip joint, the normal cervical shaft angle of an adult is 125-135 degrees, and the average cervical shaft angle is 127 degrees; the individual difference of the anteversion angles is large, and the average anteversion angle of an adult is 12-15 degrees. Patients with osteoarthritis have an increased anteversion angle, which may exceed the normal value by 10-14 ° for patients with congenital hip dysplasia, and the magnitude of the anteversion angle varies with the degree of hip dislocation.
When a patient suffers from early femoral head necrosis, femoral neck fracture, femoral head and neck tumor and tumor-like lesion or combined deformity, multiple K-wire drilling decompression is needed to be carried out on the femoral head by using multiple K-wires, or multiple K-wires are used for being driven into the femoral head neck for temporary fixation, or 1K-wire is independently used as a guide wire of other internal fixation main nails such as DHS (distributed Hash system). In clinical treatment, because the femoral neck shaft angle and the anteversion angle of each patient are different, the kirschner wire needs to be accurately driven into the center or the specific position of the femoral head and neck, and finally needs to be driven into a proper depth, so that orthopedists need to use a C-arm machine to perform multiple times of perspective and repeated operation in the clinical operation process, and finally can obtain the kirschner wire with satisfactory driving position, angle and depth. And when the fine adjustment operation is repeated, the Kirschner wire is easy to enter the original needle path, so that the adjustment is failed, even a Kirschner wire with a satisfactory position is difficult to obtain at last, and only the Kirschner wire with a common position can be used. Repeated operation and fluoroscopy not only greatly prolongs the operation time, increases the operation cost of the patient and the recovery time after the operation, but also increases the radiation quantity of the C-arm machine received by the operating doctor in the operation process. Therefore, an auxiliary device for drilling the proximal crus wire of the femur and drilling a plurality of wires is urgently needed to improve the accuracy of drilling, reduce the burden of a doctor in the operation process, shorten the operation time and reduce the operation cost of a patient.
