US 2023/0404577 A1 · IMPACT MECHANISM FOR GRASP CLAMP FIRE

Abstract

A surgical system is disclosed including an end effector and a drive system configured to effect at least one function of the end effector. The end effector includes a first jaw, a second jaw rotatable relative to said first jaw between an open configuration and a closed configuration, and a staple cartridge comprising staples removably stored therein. The drive system includes a motor and an impact mechanism including a rotary input drivable by the motor and a rotary output drivable by the rotary input. Rotation of the rotary output is configured to effect the at least one function of the end effector. The impact mechanism is configurable between a coupled state, wherein rotation of the rotary input causes corresponding rotation of the rotary output, and a slipped state, wherein the rotary input rotates relative to the rotary output.

A surgical system, comprising:

an end effector;
a drive system configured to effect at least one function of the end effector, wherein the drive system comprises an impact mechanism, comprising:
a rotary output, wherein rotation of the rotary output is configured to effect the at least one function of the end effector;
and
a rotary input configured to drive the rotary output;
wherein the impact mechanism is configurable between:
a coupled state, wherein rotation of the rotary input causes rotation of the rotary output;
and
a slipped state, wherein the rotary input rotates relative to the rotary output, wherein the impact mechanism is configurable to transition from the coupled state to the slipped state based on an occurrence of a slippage event, wherein the impact mechanism is configured to transition from the slipped state to the coupled state based on the rotary input rotating a predetermined amount relative to the rotary output in the slipped state;
and
a control system configured to determine an amount of angular rotation transferred from the rotary input to the rotary output.
