Embodiment Construction

[0026] A 3D printing occipital-cervical fusion fixation device provided by the present invention comprises the following parts:

[0027] a. If figure 1 , figure 2 , Figure 5 , Figure 6 and Figure 8 As shown, a circular occipital supporting plate 7 that matches and attaches to the surface of the trochanter of the occipital bone 9, its thickness can be selected between 2-8mm according to needs. A group of 5 guide screw holes 8 are distributed on a circumference on the occipital support plate, and the guide screw holes 8 have a guiding effect on perforating the occipital bone 9, and the occipital support plate 7 and the occipital bone 9 are fixed with screws 8a. The two sides of the lower part of the occipital bone support plate 7 are respectively provided with connected arc-shaped transition plates 4 at a certain backward twist angle. The supporting plate 7 and the cervical spine fixation plate 1 form a certain reclining angle, which is consistent with the relative angl...

Abstract

The invention relates to a 3D printing occipitocervical fusion fixing device. The 3D printing occipitocervical fusion fixing device comprises an occipital bone supporting plate (7), a set of guiding screw holes (8), a pair of cervical vertebra fixing plates (1) which are matched with the cervical vertebra and vertebral pedicle guiding screw holes (2), wherein arc transition plates (4) are arrangedat the two sides of the lower portion of the occipital bone supporting plate respectively; the device is further provided with a V-shaped bridge plate (5) which is cooperatively attached to the spinous process surface of the cervical vertebra, and a V-shaped arc fence part (6) which is connected with the V-shaped bridge plate (5) is arranged in the middle part of the V-shaped bridge plate (5), all of which forms the integrated metal 3D printing formed structure. The 3D printing occipitocervical fusion fixing device has the advantages that the 3D printing individualized customized occipitocervical fusion fixing device serves as an implantation material, cutting is not needed anymore in an operation, the device has good anatomic form matching and attaching and achieves true individualized and precise treatment, the rise of imbedding a traditional pedicle screw is effectively lowered, the success rate is increased, and the fluoroscopy time in the operation is shortened.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to an occipital-cervical fusion fixation device in orthopedic treatment. Background technique: [0002] Upper cervical spine surgery is one of the difficulties in the field of spine surgery. The anatomical structure of this part is complex and changeable, adjacent to important nerves and blood vessels, the operation time is long, and repeated fluoroscopy is required during the operation, which requires extremely high clinical skills and experience for surgeons. At present, the internal fixation devices of the neck and pillow include occipital screws and steel plates, pivot screws, and neck and pillow connecting rods. Among them, the axial pedicle is adjacent to the spinal cord and vertebral artery, so the risk of screw placement is high; the position of the occipital screw and plate is mostly determined by the anatomical relationship of the surgeon to the occipital bone during ope...
