System and method for reducing blade exposures

A computer-assisted device comprising:

• one or more driving means configured to support an instrument means, the instrument means comprising a shaft, an articulating means, a first grasping means, a second grasping means, and a cutting means, the articulating means coupling the shaft to the first grasping means and the second grasping means;
• and
• a processing means coupled to the one or more driving means;
• wherein the processing means is configured to:
• measure, using one or more first sensors, an angle between the first grasping means and the second grasping means;
• measure, using one or more second sensors, articulation of the articulating means;
• correct the angle based on the articulation of the articulating means to generate a corrected angle;
• determine a cutting length based on the corrected angle;
• and
• perform, using the one or more driving means, a cutting operation using the cutting means according to the cutting length.

• a processing means coupled to the one or more driving means;
• wherein the processing means is configured to:
• measure, using one or more first sensors, an angle between first grasping means and the second grasping means;
• measure, using one or more second sensors, a roll of the shaft;
• correct the angle based on the roll of the shaft to generate a corrected angle;
• determine a restriction on a cutting operation to be performed using the cutting means based on the corrected angle;
• and
• perform or prevent the cutting operation according to the restriction, using the one or more driving means.
