Internal fixing device for treating femoral neck fracture

Abstract

The invention relates to an internal fixing device for treating a femoral neck fracture. The internal fixing device comprises a fixed screw and an instant pressure device, wherein a first thread is arranged at the front part of the fixed screw; and the instant pressure device is arranged at the tail end of the fixed screw. The internal fixing device has the beneficial effects that an instant pressurization effect between a far-end fracture block and a near-end fracture block can be achieved through coordination of the fixed bolt and the instant pressure device; and postoperative cutting of a femoral head by a nail head is avoided through a homeopathic nail return effect, so that the shortages of a hollow screw and a lock screw plate in the prior art are overcome; and the internal fixing device is relatively applicable to treatment of an aged patient with serious osteoporosis and the femoral neck fracture. Through application of the device, achievement of minimally invasive therapy and early loading of the patient is facilitated.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to an internal fixation device for treating femoral neck fractures. Background technique [0002] Femoral neck fracture is a very common clinical fracture, especially for middle-aged and elderly people, and the incidence rate is extremely high. At present, there are two most mainstream surgical treatment methods for femoral neck fractures, one is artificial femoral head replacement, and the other is internal fixation with hollow nails. Artificial femoral head replacement is often difficult for elderly patients to tolerate due to its large surgical trauma, large blood loss, and many postoperative complications; while internal fixation with hollow nails is relatively less traumatic, with shorter operation time and less bleeding, it is suitable for elderly patients with multiple medical diseases Patients are often better suited. However, the disadvantage of intern...

Problems solved by technology

For example, the internal fixation improvement device that has recently been applied clinically It is because not only the lack of improvement in immediate compression, but also the locking of the nail plate, resulting in a high incidence of postoperative screw cutout, which has no obvious advantage compared with the current general-purpose hollow nail internal fixation
