Abstract
The present disclosure relates to adapter assemblies for use with and to electrically and mechanically interconnect electromechanical surgical devices and surgical reloads, and to surgical systems including handheld electromechanical surgical devices and adapter assemblies for connecting surgical reloads to the handheld electromechanical surgical devices.
Claims14
1-7. (canceled)
A surgical device comprising:
- a handle assembly including:
- a power source;
- a motor coupled to the power source;
- and
- a controller configured to control the motor;
- an adapter assembly configured to selectively couple to the handle assembly;
- a reload configured to selectively couple to a distal portion of the adapter assembly, the reload including a plurality of fasteners;
- and
- an anvil assembly selectively couplable to the distal portion of the adapter assembly, the anvil assembly being movable relative to the reload, wherein the controller is configured to control the motor to move the anvil assembly thereby compressing tissue between the anvil assembly and the reload at first speed for a first segment and at a second speed for a second segment, the second speed being slower than the first speed.

A surgical device comprising:
- a handle assembly including:
- a power source;
- at least one motor coupled to the power source;
- and
- a controller configured to control the motor;
- an adapter assembly configured to selectively couple to the handle assembly, the adapter assembly including a strain gauge configured to measure strain;
- a reload configured to selectively couple to a distal portion of the adapter assembly, the reload including:
- a plurality of fasteners;
- an annular staple pusher for ejecting the plurality of fasteners;
- and
- an anvil assembly selectively couplable to the distal portion of the adapter assembly, the anvil assembly being movable relative to the reload;
- wherein the controller is configured to control the motor to move the annular staple pusher based on the measured strain.
