Embodiment Construction

[0029] With reference to the accompanying drawings, a wire guide for femoral intertrochanteric fractures, a handle 1, a main guide tube 3 and a secondary guide tube 4, the handle 1 is provided with a first socket 11 for the main guide tube 3 to be inserted and a secondary guide tube The second socket 12 where the tube 4 is inserted, the proximal end of the main guiding tube 3 is connected to the handle, the proximal end of the secondary guiding tube 4 is inserted into the handle 1, and the distal end of the main guiding tube 3 is a hook The distal end of the main guide tube 3 is connected to the distal end of the secondary guide tube 4 to form a bending channel for the guide wire 2 to bypass the inner side of the intertrochanteric fracture site;

[0030] The secondary guide tube 4 is connected to the second socket 12 through the cannula 41 connected thereto, and the length and angle of the cannula 41 connected to the handle 1 are adapted to the distal end of the main guide tube...

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 steel wire guide for intertrochanteric fracture. Background technique [0002] Intertrochanteric fracture refers to the fracture between the base of the femoral neck and the lesser trochanter. 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 comminuted fractures. Many fractures, osteoporosis. [0003] Clinically, there are many surgical treatments for 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. Losing the support of the trochanter bone leads to failure. Technically, screws, steel wires, titanium cables and other methods can be used, but the fixation effect of steel wire or ti...
