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 stapling system includes an adapter assembly, a trocar assembly attachable to the adapter assembly, a processor, and memory. The memory includes instructions executable by the processor to cause the trocar assembly to move relative to the adapter assembly and determine whether the trocar assembly is properly attached to the adapter assembly. Such determination is based on an amount of force applied between the trocar assembly and the adapter assembly, an amount of current detected in the surgical stapling system, or an amount of time the trocar assembly moves relative to the adapter assembly without an indication that the amount of force is within a predetermined range.

Methods and structure for confirming proper assembly of powered surgical stapling systems

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

A surgical stapling device includes a visualization device that extends through a body of the stapling device to facilitate visualization of tissue that surrounds an end effector of the stapling device. An anvil assembly of the surgical stapling device is adapted to facilitate passage of the visualization device through the anvil assembly.

Circular stapling device with integrated visualization device

A circular stapling device includes a handle assembly, an elongate body portion that extends distally from the handle assembly, a shell assembly supported on a distal end of the elongate body portion, an anvil retainer assembly extending through the shell assembly, and an anvil assembly supported on the anvil retainer assembly. The anvil retainer assembly includes a retainer member including a retainer body and an engagement member that is pivotally supported on the retainer body. The engagement member is movable axially in relation to the retainer body from a retracted position to an advanced position to move the engagement member to from a locked position to an unlocked position in relation to the retainer body. In the unlocked position, the engagement member is movable from a non-articulated position to an articulated position in relation to the retainer body.

Circular stapling device with articulating anvil retainer assembly

An adapter assembly includes a base member, a housing, and a locking mechanism. The base member defines a longitudinal axis. The housing is rotatably secured to the base member and is rotatable in relation to the base member between a plurality of positions. The locking mechanism is supported on the housing and includes a locking member and a button. The locking member is moveable from a locked position in which a lock of the locking member is engaged with the base member to secure the housing in one of the plurality of positions to an unlocked position in which the housing is rotatable in relation to the base member. The button is positioned on the base member and is depressible to translate the locking member in a direction parallel to the longitudinal axis from the locked position to the unlocked position.

Adapter assemblies for surgical devices

A surgical device including a handle assembly, an elongated portion, and outer band assembly, and inner band assembly, a trocar assembly, and a seal assembly is disclosed. At least a portion of the outer band assembly is disposed radially within the outer sleeve. At least a portion of the trocar assembly is disposed radially within the inner band assembly. The seal assembly includes a first annular seal and a second annular seal. The first annular seal is disposed radially inward of the outer sleeve and radially outward of the outer band assembly. The second annular seal is disposed radially inward of the outer band assembly and radially outward of the inner band assembly.

Surgical device with seal assembly

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.

Retaining mechanisms for trocar assemblies

A trocar assembly for releasable engagement with an adapter assembly of a surgical stapling instrument includes a trocar mechanism that includes a trocar member that is at least one of rotatable or articulable relative to a housing of the trocar assembly.
