Embodiment 1

[0017] Embodiment 1: see figure 1 The position adjustment system for the femoral intramedullary nail shown includes a fixation component 1 connected with a fixation carrier. The fixed carrier can be a fixed frame such as a bed body or an instrument bracket, and the fixed part 1 can be a clip or other fixed parts. The fixed part 1 is a common part and will not be described in detail.

[0018] A lifting adjustment mechanism and a longitudinal adjustment mechanism are arranged on the fixed part 1 . Specifically, see figure 1 As shown, a fixed sleeve 2 is arranged on the clamping part, and a movable column 3 is matched in the fixed sleeve 2, and a vertical sleeve is installed on the upper end of the movable column 3, and the vertical rod 6 locking pin is vertically installed on the side of the vertical sleeve, and the vertical sleeve is installed vertically. Match the vertical bar 6 that is installed with the longitudinal adjustment mechanism.

Embodiment 2

[0021] Example 2: see figure 2 As shown, on the basis of Embodiment 1, the lifting regulator is to connect the fixed column 3a to the upper side of the clamping part, and the movable sleeve 2a capable of lifting and sliding is set in the middle of the fixed column 3a, and the vertical sleeve 8 is installed with the column locking pin. 4. A longitudinal sleeve is provided on the movable sleeve 2a to form a composite longitudinal sleeve. The locking pin of the longitudinal rod 6 is vertically installed on the side of the longitudinal sleeve, and the longitudinal rod 6 of the longitudinal adjustment mechanism is matched and installed in the longitudinal sleeve.

[0022] At the same time, a vertical shaft 18 and a vertical sleeve 19 are arranged in the middle of the lifting adjustment mechanism, the two are set together, and a vertical shaft locking pin 20 for locking the vertical shaft 18 is vertically connected to the side wall of the vertical shaft 19. . Thereby the three-dim...

Embodiment 3

[0023] Embodiment 3: A method for adjusting the position of the femoral intramedullary nail, using a support frame that can be adjusted in three dimensions as a basis to install a set of horizontal adjustment parts that can be pushed from the side and vertical adjustment parts that can be pushed from the vertical; The horizontal adjustment part and the vertical adjustment part are respectively aligned with the inclined end of the intramedullary nail in the femur, and the degree of inclination of the intramedullary nail in the femur is judged by X-ray observation from the upper part and the side of the intramedullary nail, and the horizontal adjustment is made according to the degree of deviation. components and vertical adjustment components for push adjustment, the adjustment methods include The horizontal adjustment part pushes the femur and the vertical adjustment part pushes the femur; The horizontal adjustment part pushes the femur and the vertical adjustment part pushe...

Abstract

The invention discloses a femoral nail position adjusting system and an adjusting method. A horizontal adjusting component which can be jacked and pushed from a side surface and a vertical adjusting component which can be jacked and pushed vertically are mounted on the basis of a support rack which can be adjusted in a three-dimensional manner; the horizontal adjusting component and the vertical adjusting component are respectively aligned to an inclined end of a femoral nail of thigh bone; and the horizontal adjusting component and the vertical adjusting component are respectively adjusted through jacking and pulling according to the inclination degree of the femoral nail till the femoral nail inside the thigh bone is in a direction accordant with that of the thigh bone. By adopting the femoral nail position adjusting system, the femoral nail which is inclined inside the thigh bone is corrected through a horizontally adjusted screw rod and a vertically adjusted screw rod. The inclination angle of the femoral nail can be adjusted at will. The femoral nail position adjusting system is simple and reasonable in structure, convenient to use, very good in effect and applicable to popularization and application.

Description

Technical field: [0001] The invention belongs to the technical field of femoral intramedullary nail locking deflection correction medical equipment, in particular to a femoral intramedullary nail position adjustment system and adjustment method. Background technique: [0002] Intramedullary nailing is a minimally invasive treatment for femoral fractures, which can be fixed firmly and provide early functional exercise. However, after the intramedullary nail is implanted into the bone, there will be a certain degree of deformation, which is difficult to correct and often requires multiple drillings to succeed. Because intramedullary nailing requires high technical requirements in the treatment of femoral fractures, it has not been fully developed. Postoperative pain is a common complication due to the deviation of the position of the intramedullary nail. The current solution is nothing more than blocking nail technology, which is difficult and has poor results. . Invention ...
