A handheld electromechanical surgical device, capable of effectuating a surgical procedure, includes a handle assembly having a power source; at least one motor coupled to the power source; and a controller configured to control the motor. The surgical device includes an adapter assembly having an electrical assembly having a proximal end in communication with the controller of the handle assembly. The surgical device includes a reload configured to selectively connect to a distal end of the adapter assembly. The reload includes an annular array of staples; an annular staple pusher for ejecting the staples; and a data storage device selectively connectable to a distal end of the electrical assembly. The data storage device receives and stores performance data of the surgical device from the controller of the handle assembly.

Handheld electromechanical surgical system

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.

A surgical instrument includes a handle assembly and an adapter assembly. The handle assembly includes a handle housing and a processor disposed within the handle housing. The adapter assembly includes a knob housing, an elongate body, a plurality of electrical components, and a flex circuit. The knob housing is configured to be connected to the handle housing. The elongate body extends distally from the knob housing and has a distal end configured to be coupled to an end effector. The electrical components are disposed within the elongate body. The flex circuit has a proximal end configured to be electrically connected to the processor, and a distal end configured to be electrically connected to the electrical components.

Adapter assemblies for interconnecting electromechanical handle assemblies and surgical loading units

An adapter assembly for connecting an end effector to an electrosurgical instrument is provided. The adapter assembly includes a drive transfer assembly, first and second pusher assemblies, a drive member, an extension assembly, and a trocar assembly. The drive transfer assembly includes first, second and third rotatable shafts. Each pusher assembly is operably connected to a rotatable shaft for converting rotational motion from one rotatable shaft to longitudinal movement to perform a different function. The drive member is operably connected to the third rotatable shaft for transferring rotational motion from the third rotatable shaft to perform a third function. The extension assembly is operably connected to a distal end of the adapter assembly and includes at least one flexible band assembly operably connected to one of the first and second pusher assemblies. The trocar assembly is configured for releasable engagement with the extension assembly.

Adapter, extension, and connector assemblies for surgical devices

The present disclosure relates to devices, systems and methods for endoscopic suturing or stitching through an access tube or the like. An endoscopic stitching device is provided and includes a handle assembly; an elongate shaft supported by and extending from the handle assembly; and an end effector supported on a distal end of the elongate shaft. The end effector includes a neck assembly configured and adapted for articulation in one direction between a substantially linear configuration and an off-axis configuration, and a pair of juxtaposed jaws pivotally associated with one another. Each jaw defines a suture needle receiving recess formed in a tissue contacting surface thereof.

Ligation clip with controlled tissue compression

A ligation clip includes a frame defining a cavity, a flexible band that is pivotably supported on one end of the frame, and a spring beam supported on the other end of the frame in cantilevered fashion. The flexible band is movable in relation to the frame from an open position to a clamped position to clamp tissue between the flexible band and the spring beam.

An adapter assembly includes an elongated body, a switch, a sensor link, and an annular member. The elongated body includes a proximal portion configured to couple to a handle assembly and a distal portion configured to couple to a surgical loading unit. The switch is configured to be toggled in response to the surgical loading unit being coupled to the distal portion of the adapter assembly. The sensor link is disposed within the distal portion of the adapter assembly and biased toward a distal position. The sensor link is longitudinally movable between a proximal position and the distal position. The annular member is disposed within the distal portion and is rotatable between a first orientation, in which the annular member prevents distal movement of the sensor link, and a second orientation, in which the sensor link moves distally to toggle the switch.

Adapter assemblies for interconnecting surgical loading units and handle assemblies

An adapter assembly for connecting a loading unit to a handle assembly includes a sleeve, a trocar assembly releasably securable with the sleeve, and a retaining mechanism configured to releasably secure the trocar assembly within the sleeve and to facilitate cleaning and sterilizing of the adapter assembly. The retaining mechanism includes first and second button members and a mechanism for maintaining the first and second button members relative to each other.
