Question

Which instrument property must be verified to avoid excessive tissue pressure during robotic grasping?

Accepted Answer

The instrument property that must be verified to avoid excessive tissue pressure during robotic grasping is jaw calibration and force feedback accuracy. Jaw calibration ensures that the opening and closing range of the robotic grasper matches the expected movement set by the surgeon&#x27;s console. If the jaws are not properly calibrated, they may close too tightly or not align correctly, leading to too much pressure on the tissue. Force feedback accuracy refers to the system&#x27;s ability to maintain consistent and controlled pressure through software-regulated motor control, even though most robotic systems do not provide direct tactile feedback to the surgeon. This means the system must apply force within safe limits automatically. For example, if a blood vessel or nerve is being held, the grasper must maintain a firm hold without crushing or slipping, which depends entirely on precise calibration and internal control of jaw tension. Verifying these properties before and during use prevents accidental tissue injury from over-compression or slippage during manipulation.
