Abstract
An orthopaedic surgical procedure includes monitoring output from a number of onboard sensors of a bone saw to detect the presence of blade deflection during advancement of the saw’s oscillating blade into the bone of a patient. Operation of the bone saw is adjusted based on the amount of detected blade deflection. A robot-assisted orthopaedic surgical system is also disclosed.
Claims20
A method of operating a robotic-assisted orthopaedic surgical system, the method comprising:
- controlling, by a computer system, a bone saw to oscillate a bone saw blade,
- operating, by the computer system, a sensor assembly positioned in the bone saw to determine an amount of blade deflection in the bone saw blade, and
- adjusting, by the computer system, operation of the bone saw based on the determined amount of blade deflection of the bone saw blade.
An orthopaedic surgical system, comprising:
- a robotic-assisted bone saw, the bone saw having a sensor assembly housed therein, and
- a computer system electrically coupled to the bone saw, the computer system being configured to:
- control the bone saw to oscillate a bone saw blade,
- operate the sensor assembly to determine an amount of blade deflection in the bone saw blade, and
- adjust operation of the bone saw based on the determined amount of blade deflection of the bone saw blade.
