A cervical fusion implant with serrations and radio opaque marking and a method thereof is disclosed The cervical fusion implant is optimized for enhanced spinal stabilization and integration. The cervical spine fusion implant is constructed from polyether ether ketone, known for its exceptional durability and biocompatibility. The implant is designed with a robust body encased in a protective capsule. The design ensures superior structural integrity and functional utility. The implant incorporates a self-stabilizing screw assembly featuring at least four lateral surfaces, each with slits to promote bone growth and integration. Additionally, the anterior surface is equipped with a screw hole for secure fixation using a titanium screw. This combination of features aims to improve spinal stabilization, promote effective fusion, and ensure long-term implant performance. Furthermore, the implants assist to maintain normal cervical curvature of the patient.

This utility model discloses a endoscopic hook knife probe, relating to the field of medical device technology. The endoscopic hook knife probe includes a handle, a rod, and a blade. The two ends of the rod are connected to the handle and the blade, respectively. The connection between the blade and the rod can be configured with a bent structure at an angle between 90° and 120°. The blade includes: a cutting edge disposed on both the inner and outer sides of the bent structure, capable of cutting tissue at the surgical site; and a blunt structure located at the front end of the bent structure, shaped as a smooth hemisphere. This endoscopic hook knife probe can be used in combination with endoscopes and other instruments to perform minimally invasive anterior cervical fusion surgery, filling a technological gap in existing domestic surgical techniques. The endoscopic hook knife probe proposed in this application effectively meets the clinical needs for minimally invasive, visualized, safe, and efficient procedures, significantly improving the ease of operation and surgical efficiency.

The utility model relates to the technical field of medical instruments, and discloses a full-porous cervical vertebra fusion cage which comprises a machining area and a porous area. The machining area is provided with a threaded hole for leading in a surgical instrument; the porous area comprises an upper surface, a lower surface, a front surface, a rear surface and two side surfaces; and the upper surface and the lower surface are provided with anti-skid surfaces. The threaded hole in the machining area is used for being matched with a surgical instrument matched with the threaded hole, and surgical implantation is facilitated. The porous area provides more growth space for cells, adhesion, migration, proliferation and differentiation of the cells are facilitated, and finally the bone ingrowth effect is achieved. The full-porous cervical vertebra fusion cage has the mechanical property matched with the human body structure and good biocompatibility, can form a tight bonding interface with the human body tissue, improves the combination stability of the fusion cage and the human body tissue, has the mechanical property matched with the human body tissue, and can be applied to clinical treatment of cervical degenerative diseases.

The invention discloses a low-incisura cervical vertebra fusion cage, and belongs to the field of orthopedic medical instruments. The fusion cage comprises a fusion cage body and a nail plate assembly, the fusion cage body comprises a top supporting plate, a bottom supporting plate and a porous structure, the space between the top supporting plate and the bottom supporting plate is filled with the porous structure, the fusion cage body is provided with a bone grafting bin penetrating through the top supporting plate, the porous structure and the bottom supporting plate, and the bone grafting bin communicates with the porous structure; the fusion cage body is provided with an implantation front end and an implantation rear end, the implantation rear end is provided with a connecting plate mechanism, the nail plate assembly is fixedly arranged at the implantation rear end of the fusion cage body through the connecting plate mechanism, and the nail plate assembly and the fusion cage body are detachably arranged. The intervertebral fusion device is reasonable in structural design, smooth and efficient in implantation operation, stable and firm in implantation use, good in bone ingrowth effect and short in postoperative recovery period of a patient, postoperative complications of the patient can be effectively reduced, and the use requirement of intervertebral fusion is met.
