Embodiment Construction

[0040] Refer to attached Figure 1-24, the minimally invasive proximal femoral internal fixation system includes an internal fixation plate, an internal fixation screw and a locking device 160 . Insert the connecting sleeve 2 of the combined lag screw 150 into the sleeve installation hole of the internal fixed steel plate, and use the surgical tool to rotate the rotating pin 8 in the locking device 160 installed on the internal fixed steel plate, and rotate with it The step of the locking disc 4 locks the connecting sleeve 2. The internal fixation plate can be a goose-head nail plate 7 or a proximal femur steel plate 170. The goose-head nail plate 7 is composed of a head and a shaft. The head of the goose-head nail plate 7 is provided with a step 72, which can be used to install The femoral tuberosity steel plate 9, the step is provided with slotted hole 71, can be used for installing hollow nail 130, is provided with connecting sleeve 2 and screw sleeve 140 installation hole...

Abstract

The invention discloses a proximal femur internal fixation system with minimal invasion, relating to an internal fixation system used for proximal femur comminuted fracture, femoral neck fracture, subtrochanteric fracture and femur backbone fracture. The internal fixation system comprises an internal fixation steel plate, an internal fixation bolt and a locking device, wherein the internal fixation steel plate adopts a dynamic hip screw steel plate or a proximal femur internal steel plate, the dynamic hip screw steel plate is composed of a head part and the rod part, and the proximal femur internal steel plate is composed of a head part and a rod part; the locking device comprises a rotary pin, a sliding pin, a spring and a locking disc; the internal fixation bolt comprises a combined tension force bolt or a combined hollow bolt, a hollow bolt, a spongy bone bolt, a cortical bone bolt and a locking bolt, wherein the combined tension force bolt is composed of a connecting sleeve, a connecting bush and a tension force bolt; the combined hollow bolt is composed of a hollow bolt and a bolt sleeve. The internal fixation steel plate and the internal fixation bolt are connected and fixedby the locking device, which can simplify operation steps, shorten operation time and leave small cut.

Description

technical field [0001] The minimally invasive proximal femoral internal fixation system of the present invention relates to an internal fixation system for proximal femoral comminuted fractures, femoral neck fractures, trochanteric fractures and femoral shaft fractures. Background technique [0002] At present, the traditional internal fixation method for proximal femoral fractures is a direct-viewing large-scale surgical operation. The product structure is complicated, the operation is difficult, the incision is long, the wound is large, there are many possibilities of serious complications, and the postoperative recovery time is long. Contents of the invention [0003] The purpose of the present invention is to provide a minimally invasive internal fixation system for the proximal femur in view of the above deficiencies. The internal fixation plate, the internal fixation screw, and the locking device are used for connection and fixation, which can simplify the operation s...
