Description
Technical Field
The invention belongs to the technical field of medical instruments, and particularly relates to a device for threading a backbone binding steel wire.
Background
In the steel wire binding, in fact, is the first internal fixation technique in the true sense. In 1775, steel wire tying was first reported in france. By the mid-nineteenth century, steel wire tying has become an important component of orthopedics.
Steel wire lashing can provide clinical help in two ways, one is as a temporary tool for maintaining reduction, and the other is as a long-term fixed use. The specific application mainly comprises the following four aspects: tension band, binding, half binding and steel wire fixation among fracture blocks.
The binding technique can be used alone or in combination with internal fixation and external fixation (steel plates, intramedullary pins, joint prostheses, etc.). In recent years, the use of this technique has dramatically increased with the incidence of periprosthetic fractures. Examples are: intertrochanteric fracture of femur, such as intertrochanteric fracture, steel wire binding, and intertrochanteric fracture of femur, such as intertrochanteric fracture, are combined with displacement of lesser trochanter. The need for repositioning and fixation increases with the increase in the size of the larger trochanteric fracture. One or more steel wires can be adopted for binding and fixing, so that the affected limb is pulled to reset the main bone block after the small trochanter bone block is stabilized.
Steel wire binding is a well-known surgical technique, but requires a relatively extensive exposure of the surgical site. The traditional steel wire guider is guided by a semi-ring to pass around the outer side of cortical bone so as to be convenient for inserting the steel wire, but the soft tissue stripping range is larger. Another common method of introducing a wire is to use an introducer with two half-rings. In the steel wire binding operation, a longitudinal incision is made on the skin surface perpendicular to the femoral shaft fracture line, a split semi-arc guide wire forceps is inserted, the guide wire forceps is pushed on the bone surface and converged on the opposite side of the femur, and at the moment, steel wires are led in and tightened and locked under the condition of maintaining fracture reduction. Since the introducer is semicircular and the shape of the shaft is irregular, muscle tissue is bound around the shaft after clamping, which leads to complications such as necrosis. In addition, the situation that soft tissues such as muscles block the pore of the wire guide clamp inevitably exists in the clamping process, so that the steel wire is difficult to be introduced.
