Apparatus and method for restoration and verification of femoral angle

Abstract

The invention provides a device for femoral angle restoration and verification, comprising: a first guide plate used for biological reconstruction of the femoral neck on the affected side and a second guide plate used for inspection after biological reconstruction, the first guide plate is used to support The lower part of the femoral head has a first structure that fits with the lesser trochanter, the outer wall of the first guide plate is provided with a Kirschner wire channel for the Kirschner wire to pass through, and the Kirschner wire channel runs through the second A guide plate; the second guide plate has a second structure fitted to the lateral part of the femur and a handle part perpendicular to the lateral wall of the second structure. Its advantages are: it will basically not affect the growth and development of children in the later stage, and it can better restore the physiological function of the femoral neck; it can reduce the difficulty of surgery for doctors, thereby reducing the operation time and bleeding volume of patients, which is beneficial to postoperative recovery of patients.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a device and method for restoring and verifying femoral angle. Background technique [0002] Femoral neck fracture refers to the fracture of the femoral neck, usually refers to the fracture between the femoral head and the base of the femoral neck. Femoral neck fractures may occur in all age groups. There are a variety of treatment methods for this type of fracture in the prior art, for example: a femoral neck medial support structure and a femoral neck fracture fixation device (201620115636.5) discloses a fixation device for femoral neck fractures, but the femoral neck cannot be collapsed. The neck-shaft angle, anteversion angle, and femoral neck length of the healthy side of the patient are effectively restored, which makes the fracture reconstruction effect poor; moreover, there is no effective inspection after the operation, so it is impossible to know whether the pos...

Problems solved by technology

There are a variety of treatment methods for this type of fracture in the prior art, for example: a femoral neck medial support structure and a femoral neck fracture fixation device (201620115636.5) discloses a fixation device for femoral neck fractures, but the femoral neck cannot be collapsed. The neck-shaft angle, anteversion angle, and femoral neck length of the healthy side of the patient are effectively restored, making the fracture reconstruction effect poor; moreover, there is no effective inspection after the operation, so it is impossible to know whether the postoperative femoral neck is well reconstructed (including the anteversion angle). , neck-shaft angle and other angles are correct), therefore, it is urgent to develop a device and method to solve the above-mentioned technical defects
