Abstract

The invention belongs to the technical field of medical auxiliary equipment, and discloses a proximal femur kirschner wire drilling positioning and multi-wire drilling auxiliary device which comprises a base, a supporting arm base, a guide hollow pipe, a transverse angle-adjustable sliding rod, a longitudinal angle-adjustable sliding rod, a C-arm perspective sighting device, a positioning part and a sliding part. The base is provided with a through hole and a first sliding groove, the supporting arm base comprises a limiting protrusion, a supporting arm and a sliding wall, the sliding wall is provided with a sliding protrusion, the guiding hollow pipe is provided with a guiding groove, the transverse angle-adjustable sliding rod is provided with a second sliding groove, a transverse sliding groove and transverse angle scales, and the longitudinal angle-adjustable sliding rod is provided with a limiting sliding ball, longitudinal angle scales and a longitudinal sliding groove. The sliding part is connected with the guide protrusion and the sliding ball. The positioning part comprises a first guide cylinder and a second guide cylinder. The problems that in the prior art, when the Kirschner wire is used for drilling the proximal femur, the accuracy rate is low, and the burden of the surgeon is heavy are solved, and the device is suitable for Kirschner wire drilling of the proximal femur.

Description

technical field [0001] The invention relates to the technical field of medical auxiliary equipment, in particular to a proximal femur Kirschner wire drilling positioning and multi-needle drilling auxiliary device. Background technique [0002] The femur is the longest tubular bone in the human body. The upper end forms the hip joint with the femoral head and the acetabulum, and the lower end forms the knee joint with the patella and the upper end of the tibia to support the body weight. There are two important angular relationships between the femoral neck and the femoral shaft. On the coronal plane, the neck-shaft axis intersects to form the neck-shaft angle; on the horizontal plane, the tibial neck axis and the transverse axis of the femoral condyle form an anteversion angle. The neck-shaft angle offsets the femoral shaft to the outside of the pelvis to meet the needs of large-scale movement of the hip joint. The normal neck-shaft angle for adults is 125°-135°, with an ave...
