Abstract

The invention relates to the field of medical instrument, and concretely relates to a sacroiliac fusion system and use method thereof. The system comprises an implant device, wherein one end of the implant device is used for clamping a fusion cage, and the other end of the implant device is provided with a guide assembly; the fusion cage having a screw hole; the guide assembly comprising a drill guide and a fixed guide, wherein a drill bit passes through the screw hole for drilling under the action of the drill guide, and a fixed part is implanted within the screw hole of the fusion cage underthe action of a fixed guide. The sacroiliac fusion system solves the problems that according to the sacroiliac fusion system in the prior art, cartilage on the joint bone surface is not removed, andthe fusion effect is poor, and a gap is generated by removing the cartilage.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a sacroiliac fusion system and a use method. Background technique [0002] Studies have shown that up to 25% of low back pain originates from the sacroiliac joints, and fusion of the sacroiliac joints can effectively treat the above problems. The application document with the application number 201180058533.X discloses a system for fixing or fusing bones with a compressive implant, which mainly includes a hollow anchor with a triangular cross-section, a nut, a spacer, and a threaded anchor body and a screw that connects the above components together in series. The threaded anchor is implanted in the sacrum, the hollow anchor is implanted in the sacrum and ilium to bear the load, the screw penetrates into the threaded anchor and the hollow anchor, the nut and the washer are screwed on the screw and are outside the ilium, Tighten the nut to apply pressure to the sacroiliac joint an...
