An adapter assembly includes a switch actuator, an actuation bar, and a latch. The switch actuator is movable between a proximal position, in which the switch actuator actuates a switch, and a distal position. The latch is movable between a first position, in which the latch permits proximal movement of the switch actuator, and a second position, in which the latch prevents proximal movement of the switch actuator. The latch is configured to move from the first position toward the second position in response to the actuation bar moving toward a proximal position.

Handheld electromechanical surgical system

An adapter assembly is provided and includes a housing for connection with a surgical device and for operative communication with at least one rotatable drive shaft of the surgical device; an outer tube having a proximal end supported by the housing and a distal end for connection with a selected end effector, wherein the distal end of the outer tube is in operative communication with each of the at least one force receiving drive member of the end effector; at least one drive transmitting/converting assembly for interconnecting a respective one of the at least one rotatable drive shaft of the surgical device and one of the at least one force receiving drive member of the end effector; and a circuit board supported in the housing and storing at least one of operating parameters and life cycle information which are unique to the adapter assembly.

Intelligent adapter assembly for use with an electromechanical surgical system

A handheld electromechanical surgical device includes a non-sterile power-pack having a drive component(s) including a rotatable drive shaft extending therefrom, a main processor configured to control each drive component, a battery configured to power each drive component, an electrical receptacle, and a control interface(s) configured to control a functionality of the drive component. A sterile outer shell housing is configured to removably encase the power-pack to define a sterile barrier thus enabling use in a surgical environment without breaking sterility. The outer shell housing includes a coupler configured to transmit a rotation from the rotatable drive shaft through the outer shell housing, a control button(s) operatively positioned such that actuation of the control button actuates the control interface, and a pass-through connector configured to transmit electrical communications from the electrical receptacle through the outer shell housing.

A surgical apparatus has a clamp and a stapling mechanism. The clamp has a first jaw and a second jaw to clamp on a body tissue at a desired location for a stapling operation. The stapling mechanism is controlled by a trigger handle or a switch assembly. The surgical apparatus has a controller for providing a delay between clamping and actuating of the firing mechanism of the stapling mechanism. The delay provides for a desired amount of time for tissue compression producing a more uniform staple formation. The surgical apparatus also has an indicator. The indicator provides feedback about the status of the stapling mechanism and also displays a time of tissue compression by the clamp.

Surgical stapler with timer and feedback display

A surgical instrument and method of controlling the surgical instrument are disclosed. The surgical instrument includes a housing and an elongated shaft that extends distally from the housing and defines a first longitudinal axis. The surgical instrument also includes a firing rod disposed in the elongated shaft and a drive mechanism disposed at least partially within the housing. The drive mechanism mechanically cooperates with the firing rod to move the firing rod. A motion sensor senses a change in the electric field (e.g., capacitance, impedance, or admittance) between the firing rod and the elongated shaft. The measurement unit determines a parameter of the motion of the firing rod, such as the position, speed, and direction of the firing rod, based on the sensed change in the electric field. A controller uses the measured parameter of the motion of the firing rod to control the drive mechanism.

Method and apparatus for determining parameters of linear motion in a surgical instrument

An authentication and information system for use in a surgical stapling device includes a handle assembly having a controller, the controller having at least one program and a memory, an adapter assembly, and a loading unit having a tool assembly mounted for articulation and a member for actuating articulation of the tool assembly, the loading unit having at least one chip assembly having a chip storing data indicating a position of the member when the tool assembly is in a fully articulated position.

Authentication and information system for reusable surgical instruments

The present disclosure relates to an electromechanical surgical system and methods for use thereof including a surgical instrument having a controller, and an end effector selectively and removably connectable to the surgical instrument, wherein the controller enters an emergency retraction mode when at least one input element of the surgical system is incapable of providing control signals to the controller to operate a motor, wherein the emergency retraction mode activates the motor to withdraw a drive assembly from any advanced position thereof.

Method of emergency retraction for electro-mechanical surgical devices and systems

A surgical instrument and method of controlling the surgical instrument are disclosed. The surgical instrument includes a housing and an elongated shaft that extends distally from the housing and defines a first longitudinal axis. The surgical instrument also includes a firing rod disposed in the elongated shaft and a drive mechanism disposed at least partially within the housing. The drive mechanism mechanically cooperates with the firing rod to move the firing rod. A sensor senses a parameter of light reflected from the surface of the firing rod, which includes markings that change the reflectivity of the firing rod. The measurement unit determines a parameter of the motion of the firing rod, such as the position and speed of the firing rod, based on the sensed parameter of the light reflected from the surface of the firing rod.
