Embodiment Construction

[0028] The spinal fixation device of the present invention will be further described in detail through specific embodiments below.

[0029] Such as figure 1 , figure 2 As shown, the spinal fixation device of the present invention is used for stabilizing the spine, and includes a bone plate, a screw 3 and a locking block 4, and the bone plate includes a longitudinally arranged first end 9, a second end 10 and one or more There are two connecting sections 11, the first end 9, the second end 10 and each connecting section 11 are provided with two nail holes arranged transversely. The bone plate includes an upper layer 1 and a lower layer 2, the upper layer is made of a first material, and the lower layer is made of a second material; the elastic modulus of the second material is smaller than that of the first material. In this implementation, the first material is titanium alloy, and the second material is polyethylene or peek. The nail hole 5 of the upper stratum is a t...

Abstract

The invention provides a spinal fixation device, and belongs to orthopaedic implants. The spinal fixation device comprises a bone lamella and screws, lamella holes are formed in the upper surface and the lower surface of the bone lamella in a penetrating mode, and the screws can be matched with the lamella holes. When the spinal fixation device is used, the screws penetrate through the lamella holes to fix the bone lamella on the bone, operation is easy, fixing is firm, and bone healing is facilitated.

Description

technical field [0001] The present invention relates to an orthopedic implant, in particular to a fixation device for stabilizing the spine. Background technique [0002] A wide variety of injuries can be inflicted on the human spine due to degeneration, tumors, and fractures and dislocations caused by physical trauma. Spinal fractures are very common, accounting for about 5%-6% of systemic fractures. Spinal fractures can be accompanied by spinal cord or cauda equina injury, especially cervical fractures and dislocations combined with spinal cord injury. It is reported that up to 70% of them can be seriously disabled or even lost their lives. The main symptoms of spinal fractures are local pain, difficulty in standing and turning over. Retroperitoneal hematoma stimulates the celiac ganglion, slows down bowel movements, and often causes abdominal pain, abdominal distension and even intestinal paralysis. Therefore, effective treatment of spinal fractures is of great signif...
