[0002] Fracture refers to the loss of bone integrity, usually caused by external impact, falls, traffic accidents and other accidents. The femur is the longest bone in the human body and bears important functions such as supporting body weight and walking. Therefore, femoral fractures have a greater impact on the human body. There are external fixation and internal fixation to treat fractures. External fixation refers to installing a fixation device on the outside of the fracture site. Through the support and fixation of the fixation device, the fracture site remains stable and promotes fracture healing. Internal fixation refers to surgically cutting the soft tissue of the fracture site and directly implanting the fixation device into the fracture site. Through the support and fixation of the fixation device, the fracture site remains stable and promotes fracture healing. Wire fixation is a type of internal fixation. Wire fixation usually passes the wire through the fracture end and fixes the fracture site by tightening the wire.

In one embodiment of the present application, the obtuse angle is 120°, and the curvature of the first clamping half ring is greater than the curvature of the second clamping half ring. In the embodiment of the present application, the first clamping half ring is in the shape of a semicircular ring, and the second clamping half ring is in the shape of a semi-ellipse.

[0008] After adopting this technical solution, by setting the first clamping semi-ring and the second clamping semi-ring to form an angle of 120° with the adjustment handle, it is helpful for the doctor to maintain a stable posture during the operation, which is more ergonomic, can reduce the doctor's fatigue, and reduce the risk of surgery. In addition, this setting reduces the obstruction of the doctor's line of sight and facilitates the surgical operation. By setting the first clamping semi-ring to be a semicircular ring and the second clamping semi-ring to be a semi-elliptical shape, the adaptability of the device is enhanced, that is, the semi-elliptical second clamping semi-ring can better adapt to bone structures of different shapes and sizes, and can increase the fit between the second clamping semi-ring and the bone, and improve the accuracy and stability of the placement of the wire. In addition, the semi-elliptical setting improves the fit with the bone, and the doctor can more accurately control the direction and depth of the wire when placing the wire, which is convenient for the doctor to operate.

[0009] Furthermore, the first clamping half ring and the second clamping half ring can be snap-connected at one end away from the hinge.

[0010] After adopting this technical solution, the first clamping half ring and the second clamping half ring can be butted against each other before the steel wire is inserted, thereby improving the accuracy of the steel wire insertion.

In an embodiment of the present application, the steel wire outlet and the first guide cavity are smoothly transitioned, and the steel wire inlet and the second guide cavity are smoothly transitioned.

[0016] After adopting this technical solution, the steel wire can smoothly pass through the steel wire inlet, and pass through the second guide cavity and the first guide cavity in sequence, and finally be led out from the steel wire outlet. The steel wire outlet and the steel wire inlet have a smooth transition with the first guide cavity and the second guide cavity respectively, making the steel wire guiding process smoother and improving efficiency.

[0017] Preferably, a tapered hole is formed at one end of the first clamping half ring, the tapered hole is connected to the first guide cavity, and an insertion end is provided at one end of the second clamping half ring, the shape of the insertion end matches the shape of the tapered hole.

[0018] After adopting this technical solution, by setting a tapered hole and an insertion end that fits the tapered hole, accurate docking of the first clamping half ring and the second clamping half ring is achieved, thereby ensuring the stability and accuracy of the guide ring during the operation. The setting of the tapered hole does not increase the width of the end of the first clamping ring, making the tissue penetration process smoother. In addition, the insertion end is pointed, which can pass through soft tissue more smoothly and reduce damage to surrounding tissues. This can not only reduce the patient's pain and recovery time, but also improve surgical efficiency.

[0019] Preferably, a first clamping piece is provided on the inner side of the first handle, a second clamping piece is provided on the inner side of the second handle, and locking teeth are provided on the opposing surfaces of the first clamping piece and the second clamping piece.

[0020] After adopting this technical solution, in the process of pinching the first handle and the second handle to drive the first clamping half ring and the second clamping half ring to dock, the first clamping part and the second clamping part are engaged with each other until the first clamping half ring and the second clamping half ring are docked. At this time, due to the first clamping part and the second clamping part, the entire device is in a stable state, ensuring that the steel wire can be stably inserted and reducing surgical risks.
