US 2026/0272453 A1 · POWERED SURGICAL INSTRUMENT

Abstract

A method of operating a surgical instrument is disclosed. The surgical instrument includes an electronic system comprising an electric motor coupled to the end effector; a motor controller coupled to the motor; a parameter threshold detection module configured to monitor multiple parameter thresholds; a sensing module configured to sense tissue compression; a processor coupled to the parameter threshold detection module and the motor controller; and a memory coupled to the processor. The memory stores executable instructions that when executed by the processor cause the processor to monitor multiple levels of action thresholds and monitor speed of the motor and increment a drive unit of the motor, sense tissue compression, and provide rate and control feedback to the user of the surgical instrument.

Dependent claims

A surgical instrument, comprising:

an end effector comprising first and second jaws for compressing tissue there between, one of the first or second jaws configured to receive a staple cartridge comprising a plurality of staples;
a motor configured to drive, during a firing stroke, a distally movable firing member through the first and second jaws to deploy the plurality of staples;
and
a processor and a memory coupled therewith, the processor being further coupled with the motor, the memory storing instructions executable by the processor to cause the processor to:
determine whether the firing stroke should be modified and,
based thereon, automatically cause the motor to at least pause driving of the firing member when the processor determines that the firing stroke should be modified.

3 more elements

A control circuit for a surgical instrument, the surgical instrument comprising an end effector comprising first and second jaws for compressing tissue there between, one of the first or second jaws configured to receive a staple cartridge comprising plurality of staples, a sensor configured to measure a parameter indicative of a then current tissue compression of tissue compressed between the first and second jaws and generate a signal indicative thereof, and a motor configured to drive, during a firing stroke, a distally movable firing member to deploy the plurality of staples, the control circuit configured to:

receive, at least periodically from the sensor during the firing stroke, the signal indicative of the parameter;
and
determine whether the firing stroke should be modified based on a comparison of the received signal to a threshold determined prior to or contemporaneously with the comparison and, based thereon, automatically cause the motor to at least pause driving of the firing member when the received signal deviates from the threshold and cause the motor to resume driving the firing member when the received signal conforms to the threshold.
