Problems solved by technology

In the past, many experts and scholars have developed some guide pin guides based on the biomechanics and geometric characteristics of the femoral neck, which have complex structures and cumbersome operations.
[0003] There is no precise guide device in the prior art, so in actual operation, it is often necessary to adjust the position of the guide pin several times under fluoroscopy for a long time to accurately fix the fracture of the femoral neck

Embodiment 1

[0025] The femoral neck guide pin guiding device of this embodiment comprises a neck-shaft angle guide, an anteversion angle guide, an awl and a locking device, and the neck-shaft angle guide includes a neck-shaft angle guide rod 8, a neck-shaft angle connecting rod 5. A neck-shaft angle guide sleeve 8, a neck-shaft angle guide rod 8 and a neck-shaft angle connecting rod 2 are vertically arranged, and a neck-shaft angle guide rod 8 and a neck-shaft angle guide sleeve 5 are arranged in parallel; the anteversion angle guide includes a The rake angle guide rod 1, a rake angle connecting rod 6, and a rake angle guide sleeve 3, the rake angle guide rod 1 and the rake angle connecting rod 6 form an included angle of 130 degrees, the rake angle guide rod 1 and the rake angle guide sleeve 3 Parallel; the locking device 4 and the tapered sleeve cooperate to fix the angle of the neck-shaft angle guide and the anteversion angle guide, wherein the diameters of the neck-shaft angle guide sl...

Embodiment 2

[0027] The difference between this embodiment and Embodiment 1 is that the femoral neck guide wire guiding device of this embodiment includes a neck-shaft angle guide, anteversion angle guide, taper sleeve and locking device, wherein the neck-shaft angle guide includes a neck-shaft angle guide Angle guide rod and a neck-shaft angle guide sleeve, the neck-shaft angle guide rod and the neck-shaft angle guide sleeve are fixedly connected in parallel; The rod and the forward angle guide sleeve are fixedly connected at an angle of 130 degrees; the taper sleeve is a hollow conical sleeve, and the neck stem angle guide sleeve and the forward angle guide sleeve are inserted into the tapered sleeve; the locking device and the cone The sleeve cooperates to fix the angles of the neck-shaft angle guide and the anteversion angle guide, wherein the diameters of the neck-shaft angle guide sleeve and the anteversion angle guide sleeve match, and one can be inserted into the other sleeve to for...

Abstract

The present invention relates to a femoral neck surgical equipment, in particular to a femoral neck guide pin guide device, which includes a neck-shaft angle guide, anteversion angle guide, a taper sleeve and a locking device, Wherein the neck-shaft angle guide device comprises a neck-shaft angle guide rod, a neck-shaft angle connecting rod, a neck-shaft angle guide sleeve, the neck-shaft angle guide rod and the neck-shaft angle connecting rod are arranged vertically, the neck-shaft angle guide rod and the neck-shaft angle guide rod The dry angle guide sleeve is arranged in parallel; the forward angle guide includes a forward angle guide rod, a forward angle connecting rod, and a guide sleeve, the forward angle guide rod and the forward angle connecting rod form an included angle of 130 degrees, and the forward angle guide rod and The anteversion guide sleeves are parallel; the femoral neck guide pin guide device of the present invention has a simple structure and a very simple operation method, and can accurately guide the guide pin into the patient's body, and can be widely used in orthopedics.

Description

technical field [0001] The invention relates to a femoral neck surgical equipment, in particular to a femoral neck guide pin guiding device. Background technique [0002] Femoral neck fractures account for 3.6% of systemic fractures and 53% to 56% of hip fractures. Due to the complexity of biomechanics of the femoral head and the particularity of local blood supply, nonunion and necrosis of the femoral head occur after femoral neck fracture. Rates were 8.9% to 40%. Closed reduction and multiple compression screws have become the mainstream internal fixation methods for femoral neck fractures, and the key to successful surgery lies in the correct direction of the guide pin in addition to reduction. In the past, many experts and scholars have developed some guide pin guides based on the biomechanics and geometric characteristics of the femoral neck, which are complex in structure and cumbersome in operation. [0003] There is no precise guide device in the prior art, so in a...
