Embodiment Construction

[0017] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0018] The present invention treats the structure of the trapezoidal locking steel plate with radian, such as figure 1 As shown, including the trapezoidal locking plate 1. The upper end of the trapezoidal locking plate 1 is narrow and the lower end is wider, and the trapezoidal surface of the trapezoidal locking plate 1 that fits the proximal end of the femur has a radian. The central position of the trapezoidal locking steel plate 1 is provided with a central hole 3 for fixing the Kirschner wire. Six locking holes 2 are set on the trapezoidal locking steel plate 1. The directions of the six locking holes 2 and the central hole 3 are parallel to each other. The hole 3 is the center, and the six locking holes 2 are divergently arranged in three directions: the upper end, the lower left end, and the lower right end. Two locking holes 2 are arr...

Abstract

The invention discloses a trapezoid locking steel plate with radian for treating femoral neck fracture, which comprises a trapezoid locking steel plate with a narrow upper end and a wide lower end; the trapezoid surface on the trapezoid locking steel plate, fit with the close end of femur, has radian; a central hole is arranged in the central position of the trapezoid locking steel plate; six locking holes are arranged in the trapezoid locking steel plate, and are parallel to the direction of the central hole; the six locking holes are arranged in a diffused manner towards the upper end, the left lower end and the right lower end by taking the central hole as the center; two locking holes are arranged in each direction; and locking bolts are arranged on the locking holes. In the invention, the locking holes which can fix the bolts in parallel are arranged on the trapezoid locking steel plate, so that the bolts can be completely fixed in parallel in the internal fixation treating link in the femoral neck fracture operation, the trapezoid locking steel plate can be placed uprightly or reversely and has radian so as to match the shape of near end of the femur, so that the bolts are hard to withdraw, the operation is simple, the time consumption is less, the fixation is reliable, and postoperation recovery is fast.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a curved trapezoidal locking steel plate for treating femoral neck fractures. Background technique [0002] Due to the development of modern transportation industry and construction industry, more and more patients suffer from femoral neck fracture. Femoral neck fracture is a common injury. Due to its local blood supply problem, it is prone to fracture nonunion and femoral head necrosis. Some materials report that the nonunion rate and femoral head necrosis rate of femoral neck fracture are 10% to 30% and 20% to 40%. %. Over the years, many scholars have explored its treatment methods, and have carried out various transformations on its internal fixation methods, from the earliest three-wing nails, multiple Kirschner wires, multiple threaded screws, to the current pressurized hollow Screws, for patients with femoral neck fractures, how to avoid the occurrenc...
