Embodiment 1

[0044] Embodiment 1: as figure 1 Shown is an example of the simplest mode of the present invention. The fixation plate is mainly aimed at the large number of components of the existing internal expansion fixation device. Each component needs to be selected according to the size of the patient. The installation is difficult and difficult during the operation. For the time-consuming problem, a conjoined board is used to solve this technical problem.

[0045] Specifically, the femoral neck plate internal fixation assembly includes a long and narrow plate body 1 that can be implanted into the femoral neck, such as Figure 9 As shown in the application state of the component plate, it can be seen that a strip-shaped flat hole is made on the bony side wall of the root of the femoral neck by grinding or drilling, and the suitable plate 1 is selected according to the size of the patient's femoral head. And insert it into the inner cavity of the femoral neck from the strip-shaped fla...

Embodiment 2

[0050] Embodiment 2: a kind of femoral neck plate type internal fixation assembly on the basis of embodiment 1, such as image 3 As shown, a circular perforation 5 is provided through the distal end of the plate body 1, and a corresponding fixing screw is provided, and the fixing screw is fixed to the circular perforation 5 after passing through the bone at the distal end of the neck. Its usage status is as Figure 11 As shown, in this embodiment, the distal end of the plate body 1 can be locked by a screw rod, so that it is integrated with the bone at the distal end of the fracture, so this embodiment is especially suitable for the situation where the fracture site occurs at the distal end of the femoral neck, but it is also Applicable if Figure 9 and Figure 13 Fractures shown in arbitrary positions. Compared with Embodiment 1, this embodiment has stronger versatility, but it is necessary to aim at the distal end of the bone to drill holes and install corresponding fixin...

Embodiment 3

[0051] Embodiment 3: a kind of femoral neck plate type internal fixation assembly on the basis of embodiment 1, such as Figure 4 As shown, the distal end of the plate body 1 runs through a strip-shaped perforation 6 extending along the length direction, and is equipped with a corresponding fixing screw, which is fixed to the strip-shaped perforation after penetrating through the bone at the distal end of the neck within 6. Its usage status is as Figure 12 As shown, in this embodiment, the distal end of the plate body 1 can be locked by a screw, so that it is integrated with the bone at the distal end of the fracture, leaving only the possibility of axial movement, but this possibility only occurs when bone resorption causes bone Later period of seam increase. In the early stage of fixation, the fixation nail is fixed as close as possible to the inner wall of the strip-shaped perforation 6, thereby providing moderate pressure at the front and rear ends of the fracture, and ...

Abstract

The invention discloses a femoral neck fracture fixing device which comprises a long and narrow plate body capable of being implanted into a femoral neck so that the two side edges of the plate body can abut against the inner wall of the neck portion of the femoral neck, the outer end of the plate body is connected with a fixing base, a fixing hole is formed in the fixing base, a fixing wire is sleeved with the fixing hole, and the two side edges of the plate body can be provided with blade portions respectively. After the plate body is implanted into the femoral neck, the plate edge can be cut into the inner wall of the neck of the femoral neck. The femoral neck fixing device can be rapidly assembled, and the aim of fixing the femoral neck is achieved. Corresponding fixing plates can be selected according to different fracture parts. The fixing plate can be clamped and fixed to the narrow area of the neck through the fixing plate, and the fracture far end and the fracture near end can be kept corresponding in position and do not swing or twist.

Description

technical field [0001] The invention belongs to the technical field of femoral neck fracture reduction and fixation devices, and in particular relates to a femoral neck fracture fixation device. Background technique [0002] The fixation of the femoral neck is mainly to fix and constrain the distal and proximal ends of the fracture to prevent the relative swing and rotation of the distal and proximal ends. The distal end of the fracture and the proximal end have a supporting force after butt joint. Because the muscle and ligament tissue itself has a traction effect, this supporting force and traction force can remain relatively stable. Therefore, the focus of fixing the distal and proximal ends of the fracture is to prevent the relative swing and turn. [0003] Femoral neck and femoral tuberosity fractures are common and frequently-occurring diseases in the elderly. When femoral neck fractures or intertrochanteric fractures are fixed with screws and nail-plate systems, the...
