To develop a probe that combines a force sensor and a diode laser for determining the contact between the tip of the optical waveguide and soft gum tissue in robot-assisted dental surgery, enabling precise specification of the cutting trajectory.
研究成果
A probe combining a single-component force sensor and the optical waveguide of a diode laser has been developed for determining contact with soft gum tissue in laser dental surgery. The study analyzed errors at waveguide–tissue contact, providing a foundation for further research and development in robot-assisted soft-tissue operations.
研究不足
The prototype probe uses a single-component sensor, imposing constraints on normal operating conditions. The probe's operation is limited to ±10° deviation of the probe axis from the normal to the sample plane. It currently allows for experimental investigation of the robot system's properties, including determination of the pressure in experiments on the pain threshold.
