Abstract

A powered surgical cutting and fastening instrument comprising an end effector, an elongate shaft, and a handle is disclosed. The end effector comprises an elongate channel, an anvil, a cartridge including a longitudinal slot, fasteners removably stored in the cartridge, a sled, and a cutting member including a laterally extending member. The handle comprises a motor configured to output a rotary motion, an adaptive control system configured to control the rate of the rotary motion, a switch for energizing the motor, and a power source configured to supply a first power to the motor and a second power to the motor. The first power and the second power are different. The first power is proportionate to a first force experienced by the end effector and the second power is proportionate to a second force experienced by the end effector. The first force is different than the second force.

Claims

1. A powered surgical cutting and fastening instrument, comprising:

an end effector, comprising;

an elongate channel;

an anvil;

a cartridge comprising a longitudinal slot;

fasteners removably stored in said cartridge;

a sled; and

a cutting member configured to be received in said longitudinal slot, wherein said cutting member is configured to move through said cartridge during a fastener firing stroke, and wherein said cutting member comprises a laterally extending member configured to couple said anvil and said elongate channel during said fastener firing stroke;

an elongate shaft, wherein said end effector extends from said elongate shaft; and

a handle, wherein said elongate shaft extends from said handle, and wherein said handle comprises;

a motor configured to output a rotary motion;

an adaptive control system configured to control the rate of said rotary motion;

a switch for energizing said motor; and

a power source configured to supply a first power to said motor and a second power to said motor, wherein said first power and said second power are different, wherein said first power is proportionate to a first force experienced by said end effector, wherein said second power is proportionate to a second force experienced by said end effector, and wherein said first force is different than said second force.

2. A powered surgical cutting and fastening instrument, comprising:

an end effector, comprising;

an elongate channel;

an anvil;

a cartridge comprising a longitudinal slot;

fasteners removably stored in said cartridge;

a sled; and

a cutting member configured to be received in said longitudinal slot, wherein said cutting member is configured to move through said cartridge during a firing stroke, and wherein said cutting member comprises a laterally extending member configured to couple said anvil and said elongate channel during a firing stroke;

an elongate shaft, wherein said end effector extends from said elongate channel; and

a handle, wherein said elongate shaft extends from said handle, and wherein said handle comprises;

a motor configured to output a rotary motion;

an adaptive control system configured to control the rate of said rotary motion;

a switch for energizing said motor; and

a power source configured to supply a first power to said motor and a second power to said motor, wherein said first power and said second power are different, wherein said first power is proportionate to a first force experienced by said cutting member during said firing stroke, wherein said second power is proportionate to a second force experienced by said cutting member during said firing stroke, and wherein said first force is different than said second force.

3. A powered surgical cutting and stapling instrument, comprising:

an end effector, comprising;

an elongate channel;

an anvil;

a cartridge comprising a longitudinal slot;

staples removably stored in said cartridge;

a sled; and

a cutting member configured to be received in said longitudinal slot, wherein said cutting member is configured to move through said cartridge during a staple firing stroke, and wherein said cutting member comprises a laterally extending member configured to couple said anvil and said elongate channel during said staple firing stroke;

an elongate shaft, wherein said end effector extends from said elongate shaft; and

a handle, wherein said elongate shaft extends from said handle, and wherein said handle comprises;

a motor configured to output a rotary motion;

an adaptive control system configured to control the rate of said rotary motion; and

a switch for energizing said motor,

wherein said motor is configured to receive a first power and a second power, wherein said second power is different than said first power, and wherein said first and second powers are proportionate to a force experienced by said end effector.
