The premise of orthopedic surgery navigation system to realize the positioning of surgical tools is to let the robot know the spatial position of the surgical path.

This process is called robot registration.

Registration refers to the alignment of different images of the same object in spatial position.

That is to calculate the mapping relationship between the robot workspace and the patient space.

In order to ensure safe and accurate surgery, the registration error of the orthopedic surgery navigation system is required to be within 0.5 mm.

High-precision robot registration involves the structure of the scale (ie, the calibration target) and the design of spatial positioning algorithms.

It is necessary to overcome problems such as patient movement during surgery, machining errors, and sensor accuracy drift.

Currently, when performing orthopedic surgery, for example, an orthopedic surgical navigation system is used to assist in vertebroplasty.

In order to ensure that the position of the surgical robot matches the position of the patient’s vertebral body, registration is required, while the traditional registration method requires the use of third-party instruments for registration.

In the registration stage, the registration needs to be completed by manually installing the ruler Registration, see the figure below.

On the one hand, this operation is cumbersome, on the other hand, the registration accuracy is closely related to the image quality, and poor image quality will affect the registration accuracy.
