Abstract

The invention provides a universal locking device of femoral neck and a femoral neck operation method. A femoral head fitting portion is provided with universal locking holes, including a first universal locking hole, a second universal locking hole, a third universal locking hole and a fourth universal locking hole; the first universal locking hole and the fourth universal locking hole are symmetrically arranged in spaced manner along the vertical direction; the second universal locking hole and the third universal locking hole are symmetrically arranged in spaced manner in the horizontal direction; a femoral shaft fitting portion is provided with two locking holes arranged evenly in spaced manner; fixing nails are tightened in the universal locking holes and the locking holes to fix thefemoral neck. The problem that an internal fixation system for femoral neck fracture operation has poor stability is solved. The femoral head fitting portion is fitted to the femoral head; the fixingnails are tightened in the four universal locking holes arranged in diamond form, and stable fixation is achieved; the fixing nails are tightened in the two locking holes for stable fixation; the femoral head experiences small sinking and horizontal displacements; the operations are simple, and less surgical pain is caused to patients.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a femoral neck universal locking device and a femoral neck operation method. Background technique [0002] Femoral neck fracture is the most common injury disease of the hip, which often occurs in the elderly. The internal bone strength of the elderly decreases. Double quantum densitometer confirms that the femoral head tension bone trabecula becomes thinner, and the number of settings disappears, making the femoral head fragile. Therefore, it does not require much violence, such as slipping on flat ground, falling from the bed, or sudden twisting of the lower limbs, all fractures will occur; femoral neck fractures in adolescents are often caused by serious injuries, such as car accidents or falls from heights. [0003] Femoral neck fractures have a high probability of femoral head necrosis and fracture nonunion, most of which require surgical treatment. In the process ...
