[0002] During the operation, due to the large number of surgical instruments required and the cumbersome installation steps of each of them, doctors usually need to spend a lot of time preparing these devices before the operation starts. If an instrument needs to be replaced during the operation, it is difficult for the surgical staff to operate the small installation tools flexibly because they are wearing gloves. This not only increases the installation difficulty but also significantly prolongs the operation time and increases the patient's risk. In addition, when operating while wearing gloves, the situation of the instrument slipping frequently occurs. This not only may cause instrument contamination but also may cause it to be unable to be used continuously, further affecting the operation process and efficiency. In view of the problems of how to better install various surgical instrument tools, it is particularly important to optimize the instrument design and improve the preoperative preparation process.

[0003] Therefore, a quick-change interface tool under a navigation system is needed to improve the above problems. Content of the Utility Model
