Abstract Objective: To overcome the drawbacks of the current instruments, a series of novel endoscopic instruments was designed and its feasibility in endoscopic transcervical odontoidectomy was assessed. Methods: In 1 fresh frozen adult cadaver, the series of novel endoscopic instruments was applied for endoscopic transcervical odontoidectomy. Sixteen formalin-fixed adult cadavers were randomly divided into two groups (the experimental group and the control group). In the experimental group, the series of novel endoscopic instruments was applied. And in the control group, conventional surgical instruments were applied. Cooperating between the instruments in left and right anterior transcervical approaches, all the 16 formalin-fixed cadavers underwent endoscopic transcervical odontoidectomy. The operating time and X-ray exposure frequency of the two groups were recorded. Results: In all cadavers, the anterior arch of atlas and odontoid were successfully resected. The expected advantages of the series of novel endoscopic instruments were achieved. Compared with the control group, the experimental group showed superiority in the operating time and X-ray exposure frequency. Conclusion: The series of novel endoscopic instruments can overcome the drawbacks of the current instruments for endoscopic cervical surgery. Cooperating between the instruments in left and right approaches, the series of novel endoscopic instruments can reduce the operating time and X-ray exposure frequencies, and can make the operation safer, more convenient and more accurate.
