Objective:Using the superiorities of the computer in processing graphics and data,to exted the clinical application of the stereotactic operation and improve its safety, accuracy and practicality. Methods:Based on BH robot stereotactic system, by applying the CT graphics technology to perform stereotactic operations for six types of diseases mainly introcranial occupying lesions. Results:Have performed 50 operations of 42 cases smoothly and successfully, the success percentage of shortly postoperative improvement is up to 100% and pathological diagnosis accordance is 95%. Conclusion:The rationally designed computer aided stereotactic system excels at the serviceabelity, it can give us clear graphic processing, accurate target-choosing and the credibility of three-dimensional coordinate data. The convenience, simpleness, rapidness and high safety invest it the extensive clinical practical value.
