Embodiment

[0050] Embodiment: according to specification Figure 1-5 It can be seen that, firstly, the movable device can be moved to the side of the patient's operating bed through the rollers on the lower wall of the main body box 1, and after the power is turned on; 32, then rotate the first screw rod 35 through the runner 36, make it pass through the baffle plate 33 limit rotation, make the first moving block 34 move in the mounting frame 31 under force, drive the moving rod 37 translation, and then make the legs The clamp 38 moves to the supporting plate 32 to limit and clamp the thigh to avoid movement during the operation; then according to the operation position, the hydraulic cylinder 21 in the adjustment structure 2 is controlled by the touch panel 6 to drive, and the carrier frame 22 is adjusted in the main body frame At the same time, the drive of the motor 25 is controlled. After the first gear 23 and the second gear 26 are meshed and transmitted, the bearing arm 24 is force...

Abstract

The invention discloses a device for fixing lesser trochanter of femur for the clinical bone fracture surgery department. The device comprises a main body box, an adjusting structure movably arrangedon the main body box, a leg fixing structure fixedly arranged on the rear side wall of the main body box and a limiting structure movably arranged on the adjusting structure. The invention relates tothe technical field of orthopedic medicine. The distance for fixing the lesser trochanter of femur can be adjusted according to the distance of the surgical leg through the adjusting structure, the thigh of the human body can be limited and prevented from moving through leg fixing, surgical operation is facilitated, the lesser trochanter of femur can be fixed at the corresponding position by equipment through the limiting structure, the leg fixing structure and the adjusting structure are matched, multi-directional fixing is achieved, and after fixing, the lesser trochanter of femur is conveniently fixed through steel nails.

Description

technical field [0001] The invention relates to the technical field of orthopedic medicine, in particular to a lesser trochanter fixation device for clinical orthopedic surgery. Background technique [0002] The femur, also known as the femur, the thigh bone, and the bone, 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; the proximal end has a round The femoral head is 2 / 3 of the sphere, pointing inward and forward, and forms the hip joint with the acetabulum; there is a small socket in the center of the femoral head called the femoral head concave, and the narrow part below the femoral head is the femoral neck, between the femoral neck and the femoral body The included angle is 125°; [0003] There are two large protrusions on the distal side of the femoral neck: the greater trochanter a...
