Tractor for greater trochanter of femur

Abstract

The invention discloses a tractor for the greater trochanter of the femur, which comprises a pulling screw and a traction ring, the pulling screw is provided with a transverse passage through which a guide needle can pass, the traction ring is connected with the end of the pulling screw, and the longitudinal height of the traction ring is greater than the diameter of the pulling screw. The tractor for the greater trochanter of the femur provided by the invention has a simple and ingenious structure, is convenient to use, is applicable to cases such as the displaced pelvic ring fracture, the central dislocation of the hip joint and old posterior hip joint dislocation accompanied by fractures around the knee joint or skin and soft tissue infection around the knee joint, and also is suitable for continued traction when the traction of the tubercle of the tibia is too long, traction screws are loose or screw holes are infected and the traction screws have to be replaced.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a tractor for the greater trochanter of the femur. Background technique [0002] Displaced pelvic ring fractures, central dislocation of the hip joint, and old posterior hip dislocation require bone traction before surgery to facilitate reduction during surgery. At present, femoral supracondylar bone traction is usually used. The specific operation steps are as follows: [0003] Put the injured lower limb on the Brown traction support, and draw a horizontal line perpendicular to the femur within 1cm proximal to the upper edge of the patella (for the elderly with osteoporosis, the nail should be higher than the upper edge of the patella, and for young adults with hard bones) , the nail should be closer to the upper edge of the patella). Then along the anterior edge of the fibular head and the highest point of the medial femoral condyle, draw a vertical line that intersects with...

AI Technical Summary

Problems solved by technology

However, for displaced pelvic ring fractures, central dislocation of the hip joint, and old posterior hip dislocation combined with fractures around the knee joint or skin and soft tissue infection around the knee joint, the supracondylar bone traction technique above cannot be applied. Therefore, It is necessary to provide a new femoral greater trochanter bone distractor, which is suitable for bone distraction in the above-mentioned situations
