A surgical instrument includes a surgical end effector having at least one actuation assembly to effect a surgical procedure when actuated, an electric motor operationally connected to the end effector to operate the at least one actuation assembly, and a power supply electrically connected to the motor and selectively powering the motor to actuate the actuation assembly. The power supply has a battery cell with a critical current rate and, when activated to power the motor and actuate the actuation assembly, operates the cell at a super-critical current rate or at an average current rate above the critical current rate. The power supply selectively powers the motor to actuate the assembly less than 16 times during a clinical life of at least one of the end effector, the motor, and the power supply.

A surgical instrument includes an end effector having an actuator effecting a surgical procedure when actuated, an electric motor operating the actuator, and a power supply actuating the actuator when power is supplied to the motor. The power supply has a battery cell with a given rated power for an operating period of over 15 seconds and for a total aggregate operating time of over 300 seconds. The motor and power supply are configured to utilize the battery cell at a power greater than the given rated power. The motor characteristics are selected to utilize the battery cell for periods of operation of less than 16 seconds and for a total aggregate operating time of less than 300 seconds. A one-handed handle contains all of the power supply, at least part of an anvil control assembly, and at least part of an electrically-powered stapler/cutter control assembly.

An electrically powered surgical instrument includes a surgical end effector having a surgical procedure effecting actuation assembly. A handle is coupled with the end effector. An electric motor is disposed within a shell of the handle and has power terminals and a drive train actuating the assembly when the motor is supplied with power. A break-before-make power supply switch at the handle selectively controls supply of power to the motor. A post-termination braking circuit electrically short-circuits the power terminals when the switch does not supply power to the motor. A method for post-termination braking of an electrical motor utilizes the permanent magnetic field of the motor to counteract an inertia-induced over-stroke characteristic of the motor, drive train, and/or actuation assembly after powered operation by short-circuiting the still-spinning motor to create an electrically generated magnetic field in opposition to the permanent magnetic field upon ceasing supply of power to the motor.

An electrically operated surgical instrument includes a surgical end effector having an actuation assembly effecting a surgical procedure when actuated and a handle connected to the end effector for actuating the assembly. A part of the assembly moves between start and fully actuated positions. The handle has a self-contained power supply and a drive assembly disposed entirely within the handle. The drive assembly has an electrically powered motor and a controller electrically connected to the power supply and to the motor. The controller selectively operates the motor. A transmission mechanically connects the motor to the moving part and selectively displaces the moving part anywhere between the start and fully extended positions when the motor is operated. A manual release is mechanically coupled to the transmission to selectively interrupt the transmission and, during interruption, displaces the moving part towards the start position independent of motor operation.

A surgical instrument includes an end effector having an actuation assembly to effect a surgical procedure when actuated.

When activated to power the motor and actuate the actuation assembly, the power supply operates the battery cell at a super-critical current rate during a non-zero super-critical pulse discharge period lasting less than approximately 16 seconds. The power supply operates the motor above the rated operating voltage during the super-critical pulse discharge period.
