Robotic Surgery Force Feedback

Invasive robotic surgery demands a level of force precision most applications never need, since the surgeon's movements are mirrored by a robotic arm in real time and every bit of haptic feedback has to be measured accurately to keep the patient safe. A biomechanical medical company used a combination of Interface sensors to validate exactly this: the ConvexBT Load Button Load Cell measuring force at the surgical tools themselves, such as clamps and pinchers; the SMTM Micro S-Type Load Cell mounted at the tool attachment point to capture forces applied to the tools directly; and the MRTP Miniature Overload Protected Flange Style Reaction Torque Transducer mounted between the arm's motor and joint to measure movement torque. All three feed into a BX8 8-Channel Data Acquisition System and Amplifier, giving engineers a complete, recorded picture of force and torque that confirms the robotic arm applies exactly the right amount of force during an incision, and moves smoothly enough to mirror the surgeon's own movements.
