Embodiment 1

[0031] like Figure 1-3 As shown, this embodiment provides a spinal internal fixation device, comprising: a device main body 1 and a plurality of nail bodies 2 threadedly connected to the device main body 1;

[0032] The device main body 1 includes: a fixing plate 11 , a first chute 12 , a guiding plate 13 , a second sliding slot 14 , a positioning plate 15 and a screw hole 16 ; the fixing plate 11 has a certain A curved elongated plate, the fixing plate 11 has the first chute 12 penetrating through both sides in the vertical direction, and the fixing plate 11 has a penetrating opening on one side in the horizontal direction. The second chute 14; the first chute 12 is slidably provided with a number of the guide plate bodies 13, the top of the guide plate body 13 extends to both sides, the guide plate body 13 The extension part is slidably arranged in the second chute 14 , and the extension part on one side of the guide plate body 13 penetrates the fixing plate body 11 , and ...

Embodiment 2

[0042] This embodiment provides a method for preparing a spinal internal fixation device as described in Embodiment 1, the steps comprising:

[0043] S1. Obtain the shape data of the spine by means of CT scanning, and establish a three-dimensional model of the spine;

[0044] S2. According to the three-dimensional model established in step S1, determine the number of the guide plate bodies 13, the shape of the positioning plate body 15, the axial direction of the screw holes 16 and the length of the nail body 2, so that the The positioning plate body 15 is fitted to the spine, while the nail body 2 can completely fix the spine, and the three-dimensional models of the device main body 1 and the nail body 2 are established respectively;

[0045] S3. According to the three-dimensional model established in step S2, three-dimensionally print a corresponding number of the guide plate body 13 and the positioning plate body 15 (both of which are integrally formed), and then print the ...

Abstract

The invention relates to a spinal internal fixing device. The spinal internal fixing device comprises a device main body and a plurality of nail bodies in threaded connection with the device main body, the device body comprises a fixing plate body, a first sliding groove, a guiding plate body, a second sliding groove, a positioning plate body and a screw hole. The screw body comprises a connecting part used for being connected with a device body and a combining part used for being connected with a vertebral body. The internal fixation device for the spine can be attached to the spine, in the nailing process, the position of the guide plate body is moved to prevent the insertion point of the nail body from being lost, meanwhile, the requirement for internal fixation of the spine is met, and the risk of an operation is reduced.

Description

technical field [0001] The invention relates to medical device technology, in particular to a spinal internal fixation device and a preparation method thereof. Background technique [0002] Spinal internal fixation technology is a milestone in the development of spine surgery. It is widely used in the treatment of spinal diseases and trauma, and is a must-have expertise for spine surgeons. However, the existing spinal internal fixation devices are not yet able to meet the needs of spinal internal fixation technology. [0003] Therefore, there is an urgent need for a spinal internal fixation device and a preparation method thereof. SUMMARY OF THE INVENTION [0004] The purpose of the present invention is to provide a spinal internal fixation device and a preparation method thereof in view of the deficiencies in the prior art. [0005] For realizing the above-mentioned purpose, the technical scheme that the present invention takes is: [0006] A first aspect of the presen...
