Clinical Trial Inclusion Criteria and Evaluation Metrics

The inclusion criteria are based on the experimental requirements and product characteristics, but they will not be elaborated on at this time. The primary evaluation index is clinical success rate, which is determined by the use of instruments during the surgical process to judge whether the clinical use of the experimental instruments is successful, and to calculate the proportion of clinical success in each group. Secondary evaluation indexes generally include image quality evaluation, operational performance evaluation, stability evaluation, surgical time, blood loss, drainage volume, etc.
