US 12,653,602 B2 · Modular battery powered handheld surgical instrument with selective application of energy based on button displacement, intensity, or local tissue characterization

Abstract

A surgical instrument comprises a controller configured to control application of RF or ultrasonic energy at a low level when displacement or intensity of a button is above a first threshold but below a second threshold higher than the first threshold, and control application of RF or ultrasonic energy at a high level when the displacement or intensity exceeds the second threshold. In another aspect, a surgical instrument comprises a first sensor configured to measure a tissue characteristic at a first location, a second sensor configured to measure the tissue characteristic at a second location, and a controller configured to, based at least in part on the measured tissue characteristic at the first location and the second location, control application of RF or ultrasonic energy.

Dependent claims

A controller usable with a surgical instrument, wherein the controller comprises:

a circuit comprising an input and an output, wherein the circuit is configured to:
receive, at the input, a signal from a sensor, wherein the signal corresponds to a displacement measurement of a button of the surgical instrument;
and
control, at the output, a first energy output or a second energy output as a function of the displacement measurement according to a non-linear curve, such that:
a first change in the displacement measurement results in a first disproportional change in energy output within a first range of the non-linear curve;
and
a second change in the displacement measurement results in a second disproportional change in energy output within a second range of the non-linear curve;
wherein the second change is greater than the first change;
and
wherein the first disproportional change is greater than the second disproportional change.
