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.

A coupling system includes an applicator tool and an attachment ring mounted on the applicator tool. Clips are contained within the applicator tool and are deployed through the attachment ring in order to anchor the attachment ring to biological tissue. When deployed, tips of the clips follow a curved trajectory through an annular cuff of the attachment ring and through the underlying tissue. The tips loop back out of the tissue and to a location where they are later trapped or clamped by the attachment ring. While the tips are trapped or clamped, the applicator tool cinches the clips by pulling rear segments of the clips. Thereafter, the applicator tool disconnects from the attachment ring which remains anchored to the tissue and serves as a coupling for a cannula. The cannula can have movable lock members that secure it to the attachment ring.

A control system for a surgical instrument. The control system includes an RFID scanner and a control circuit coupled to the RFID scanner. The control circuit is configured to receive data from RFID tags associated with devices and/or users, determine a type of the surgical instrument being utilized or surgical procedure being performed according to the received data, and determine an operational setting for the surgical instrument or another device within the surgical system, which may be tailored according to the particular user identity scanned by the RFID scanner.

A method of operating a surgical assembly is disclosed. The method includes receiving a first input from a first RFID scanner indicative of a first information stored in a first RFID chip of a first modular component of the surgical assembly, receiving a second input from a second RFID scanner indicative of a second information stored in a second RFID chip of a second modular component of the surgical assembly, determining an operational parameter of a motor of the surgical assembly based on the first input and the second input, and causing the motor to effect a tissue treatment motion of the first modular component.

A surgical device includes a handle assembly having: a power source, a motor coupled to the power source, and a controller configured to control the motor. The device also includes an adapter assembly configured to selectively couple to the handle assembly. The adapter assembly includes a clamping transmission assembly movable by the motor. The device also includes a reload configured to selectively couple to a distal portion of the adapter assembly, the reload including a plurality of staples ejectable from the reload. The device further includes an anvil assembly selectively couplable to the distal portion of the adapter assembly and movable relative to the reload. The controller is further configured to control the motor to move the clamping transmission assembly to move the anvil assembly from a distal clamp position to a proximal clamp position and then distally from the proximal clamp position to reduce clamp force.

A fastener cartridge can comprise a support portion, a tissue thickness compensator positioned relative to the support portion, and a plurality of fasteners positioned within the support portion and/or the tissue thickness compensator which can be utilized to fasten tissue. In use, the fastener cartridge can be positioned in a first jaw of a surgical fastening device, wherein a second jaw, or anvil, can be positioned opposite the first jaw. To deploy the fasteners, a staple-deploying member is advanced through the fastener cartridge to move the fasteners toward the anvil. As the fasteners are deployed, the fasteners can capture at least a portion of the tissue thickness compensator therein along with at least a portion of the tissue being fastened.

The present invention relates to a complex surgical device for carrying out an anastomosis in the intestine including: a- a protective device (5) comprising an anchor element consisting of a stent (1) and a flexible outer sheath (2), and b- an introducer (10) comprising at least a first deformable guide tube (12), characterized in that the downstream end of said outer sheath is connected to said first guide tube (12) or to a first connecting piece (11), said outer sheath (2) being folded inside said first deformable guide tube (12), said stent being held in radial compression inside said first deformable guide tube.

An anvil assembly is disclosed that includes an anvil shaft including a proximal portion and a distal portion and defining a first longitudinal bore. The proximal portion includes a plurality of flexible legs that define the first longitudinal bore dimensioned to receive a trocar of a stapling device. An anvil head assembly is secured to the distal portion of the anvil shaft and supports an annular anvil plate that a plurality of staple deforming pockets. The anvil assembly also includes a rigid collet defining a second longitudinal bore that is configured to receive the trocar of the stapling device. The rigid collet is supported within the first longitudinal bore and is positioned to prevent crushing of the plurality of flexible legs when the anvil assembly is manipulated with a grasper.

The present invention relates to an egg-shaped stapler for intestinal anastomosis, the stapler including: an anvil head having an oval bottom inner circumferential surface; a rear head which has an oval bottom inner circumferential surface that comes into contact with the bottom inner circumferential surface of the anvil head and which includes a staple receiving port for receiving a staple along the oval bottom inner circumferential surface thereof; and a handle part, one end of which is coupled to the rear head and the other end of which extends backwards so as to operate at least one of the anvil head and the rear head.

A stapling assembly comprising a tissue thickness compensator is disclosed. The tissue thickness compensator comprises a body portion comprising a porous material and a plurality of cavities defined in the body portion, wherein the cavities are aligned with forming surfaces of an anvil such that fasteners of a fastener cartridge are configured to at least one of the cavities when the fasteners are ejected from the fastener cartridge or capture the cavities and compress the cavities within the tissue thickness compensator when the fasteners are ejected from the fastener cartridge and formed by forming surfaces of the anvil. The stapling assembly further comprises at least one medicament positioned within each cavity prior to firing the stapler, wherein the medicament is different than the porous material.
