Embodiment Construction

[0029] Referring to the accompanying drawings, a wire guide for intertrochanteric fractures, a handle 1, a main guide tube 3 and a secondary guide tube 4, the handle 1 is provided with a first insertion hole 11 for the main guide tube 3 to be inserted and a secondary guide The second jack 12 into which the tube 4 is inserted, the proximal end of the main guide tube 3 is connected to the handle, the proximal end of the auxiliary guide tube 4 is inserted into the handle 1, and the distal end of the main guide tube 3 is a hook The lesser trochanteric fracture fragment is hooked, and the distal end of the main guide tube 3 is connected with the distal end of the auxiliary guide tube 4 to form a bending channel for the guide wire 2 to bypass the inner side of the intertrochanteric fracture site of the femur;

[0030] The auxiliary guide tube 4 is connected to the second insertion hole 12 through the cannula 41 connected to it. The length and angle of the cannula 41 connecting the ha...

Abstract

Disclosed is a steel wire guiding device for an intertrochanteric fracture. A first inserting hole which allows a main guiding catheter to be inserted and a second inserting hole which allows an auxiliary guiding catheter to be inserted are formed in a handle, the near end of the main guiding catheter and the near end of the auxiliary guiding catheter are respectively in inserted connection with the handle, the far end of the main guiding catheter is in a hook shape and hooks small trochanteric fracture blocks in a sleeved mode, the far end of the main guiding catheter and the far end of the auxiliary guiding catheter are connected, and therefore a bent channel which guides a steel wire to be wound around the position of the intertrochanteric fracture is formed. A hole which allows a steel wire ejection position to penetrate is formed in one side of the main guiding catheter, a gap which allows the steel wire to pull away is formed in the other side of the main guiding catheter, the handle is further connected with a pushing mechanism, the pushing mechanism comprises a pushing rod which is inserted in the handle, a screw rod which is in threaded connection with the handle is arranged at the tail end of the pushing rod, and the fracture position is jointly fixed by the main guiding catheter and the pushing mechanism. A combined type guide steel wire or a titanium cable and a device for temporarily fixing the fracture are adopted, the tissue is rarely damaged, fracture healing is facilitated, minimally-invasive operation is achieved, use is convenient, and the operation is easy, convenient and reliable.

Description

technical field [0001] The invention relates to a wire guide for intertrochanteric fractures of the femur. Background technique [0002] Intertrochanteric fracture refers to the fracture between the base of the femoral neck and the lesser trochanter of the femur. It is one of the most common fractures in the elderly, especially in the elderly over 70 years old and patients with severe osteoporosis. The fracture is characterized by comminution. Fractures and osteoporosis. [0003] Clinically, there are many surgical treatments for femoral intertrochanteric fractures, including various internal fixation operations or artificial joint replacement operations. However, comminuted intertrochanteric fractures require additional fixation of the fracture fragments to avoid internal fixation or artificial joint surgery. Loss of the support of the trochanteric bone leads to failure. Technically, methods such as screws, steel wires, and titanium cables can be used, but the fixation eff...
