1. A surgical system comprising:
a resection controller coupled to a motor in a handpiece, and the handpiece coupled to a resection instrument defining a cutting element, and the handpiece comprises an interface device defined on an exterior surface of the handpiece;
a peristaltic pump controller coupled to a motor of a peristaltic pump, the peristaltic pump coupled to a suction lumen of the resection instrument;
the surgical system is configured to:
drive the motor within the handpiece to cause mechanical resection of tissue by the resection instrument;
aspirate fluid and tissue fragments through the suction lumen of the resection instrument during the mechanical resection of tissue; and
modulate a speed of the peristaltic pump during the driving and aspirating, wherein the modulation is responsive to the interface device by the surgical system being configured to
read the interface device, wherein the interface device is a positional-interface device defined on the handpiece, and wherein the reading results in a position associated with the positional-interface device, and
set the speed of the peristaltic pump based on the position such that the speed of the peristaltic pump is directly and exclusively controlled based on the position.
