Summary
Automated bone drilling enhances surgical accuracy and patient safety by precisely controlling parameters like force and temperature, overcoming manual drilling limitations. This technology offers a user-friendly solution for orthopaedic procedures.
Area of Science:
- Orthopaedic surgery
- Robotics in medicine
- Biomechanical engineering
Background:
- Manual drilling in orthopaedics presents challenges including accuracy issues, risk to blood vessels, and bone overheating.
- Automated drilling systems are recommended to mitigate these risks and reduce human error.
Purpose of the Study:
- To investigate and identify key technical parameters influencing the bone drilling process.
- To experimentally evaluate bone resistance force and temperature during automated drilling.
Main Methods:
- Monitoring drilling parameters: time, linear and angular velocity, resistance force, penetration depth, and temperature.
- Experimental identification of technical drilling parameters and bone resistance force.
- Utilizing an experimental setup to analyze drilling dynamics.
Main Results:
- Achieved drilling accuracy with an error of less than 0.2 mm.
- Maintained bone temperature within tolerable limits during the drilling process.
- Presented experimental data on drilling velocities, bit diameters, penetration depths, resistance force, and temperature over time.
Conclusions:
- Automated bone drilling effectively resolves issues associated with manual techniques, enhancing patient safety.
- The developed experimental setup allows for precise identification of bone drilling parameters, including resistance force and mechanical torque.
- The robotic system is user-friendly, offering real-time data collection and simplified task setting for orthopaedic surgeons.
