Problems solved by technology

[0006] Aiming at the problem that at least three fixation nails are required in different directions in the existing femoral neck fixation method, but each fixation nail has fewer contact points with the bone, and the degree of firmness is poor; the number of components of the existing internal expansion fixation device is large Each component also needs to be selected according to the size of the patient. The installation is difficult and time-consuming during the operation. The present invention provides a femoral neck plate internal fixation component that can be quickly assembled to achieve the purpose of fixing the femoral neck.

Embodiment 1

[0046] Example 1: as figure 1 Shown is an example of the simplest mode of the present invention. The fixing plate is mainly aimed at the large number of components of the existing internal expansion type fixing device, and each component also needs to select a suitable component according to the patient's body shape, which is difficult to install during the operation. For the time-consuming problem, a conjoined board is used to solve the technical problem.

[0047] Specifically, the femoral neck plate-type internal fixation assembly includes a long and narrow plate body 1 that can be implanted into the femoral neck, such as Figure 9 The application state of the component plate is shown. It can be seen that a strip-shaped flat hole is opened in the bone side wall of the femoral neck root by grinding or drilling, and the appropriate plate 1 is selected according to the size of the patient's femoral head. And insert it into the femoral neck cavity from the strip-shaped flat ho...

Embodiment 2

[0052] Embodiment 2: a femoral neck plate type internal fixation component based on Embodiment 1, such as image 3 As shown, a circular perforation 5 is provided through the distal end of the plate body 1, and is equipped with a corresponding fixing screw, which is fixed to the circular perforation 5 after passing through the bone at the distal end of the neck. Its use status is as Figure 11 As shown, this embodiment can lock the distal end of the plate body 1 through a screw rod, so that it can be fixed with the bone at the distal end of the fracture as a whole, so this embodiment is especially suitable for the case where the fracture site occurs at the distal end of the femoral neck, but also Applies to as Figure 9 and Figure 13 The fracture shown is in an arbitrary position. Compared with Embodiment 1, this embodiment is more versatile, but needs to drill a hole at the distal end of the bone and install the corresponding fixation wire 15 . from Figure 11 It can be ...

Embodiment 3

[0053] Embodiment 3: a femoral neck plate type internal fixation component based on Embodiment 1, such as Figure 4 As shown, the distal end of the plate body 1 penetrates a strip-shaped perforation 6 extending in the length direction, and is equipped with a corresponding fixing screw, which is fixed to the strip-shaped perforation after passing through the bone at the distal end of the neck. 6 within. Its use status is as Figure 12 As shown, in this embodiment, the distal end of the plate body 1 can be locked by a screw rod, so that it can be fixed with the bone at the distal end of the fracture as a whole, and only the possibility of axial movement is retained, but this possibility only occurs when bone resorption leads to bone loss. Seams increase later. In the early stage of fixation, the fixation nail is fixed as soon as possible close to the inner wall of the bar-shaped perforation 6, thereby providing moderate pressure at the front and rear ends of the fracture. This...

Abstract

The invention discloses a femoral neck plate-type internal fixing assembly 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 restrain the distal and proximal ends of the fracture to prevent the relative swing and rotation of the distal and proximal ends. The distal end and proximal end of the fracture have supporting strength after docking. Because the muscle and ligament tissue itself has a traction effect, this supporting force and traction force can maintain relative stability. Therefore, the focus of fixing the distal and proximal ends of the fracture is to prevent the distal and proximal ends from swinging relative to each other. 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...
