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.

Endoscopic stitching devices

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

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

A seal assembly is provided for reception of an elongated surgical instrument, which comprises a body having at least one opening configured and dimensioned to permit entry of an elongated surgical instrument and defining a central longitudinal axis; a seal member formed of a resilient material and defining an aperture therein, the aperture being configured and dimensioned such that insertion of the surgical instrument into the aperture causes the resilient material defining the aperture to resiliently contact the outer surface of the surgical instrument in a substantially fluid tight manner, the seal member further including a peripheral flange element which contacts a surface of the body to form a contact seal therewith; and a fabric layer juxtaposed relative to the resilient material. The seal assembly may further include a coating applied to the seal member to reduce friction between the seal member and surgical instrumentation inserted therein. The coating is preferably a hydrocyclosiloxane membrane prepared by plasma polymerization process.

Trocar seal system

A removal pouch that is utilized for removing body tissue from the interior of the body as part of a minimally invasive surgical procedure. The specimen removal pouch includes an elongated body and a gas vent. The elongated body has an interior portion to collect specimen from a body cavity of a patient. The gas vent is configured to allow passage of gas from the interior portion of the elongated body to an external environment during removal of the pouch from within the body cavity of a patient.

Specimen removal device with gas venting

A specimen retrieval device includes an applicator. A specimen retrieval pouch is operably disposed within the applicator and deployable therefrom. The specimen retrieval pouch defines a longitudinal axis therethrough and includes a closed bottom portion and an open upper portion. The closed bottom portion includes a plurality of spikes configured to grasp a specimen positioned within the confines closed bottom portion. The upper closed portion includes one or more axial folds that are movable from a folded configuration to an unfolded configuration when a predetermined force is applied to a portion of the specimen retrieval pouch.

Specimen retrieval device

An articulation mechanism for a surgical instrument includes an articulation assembly, a plurality of cables, and a trigger. The cables are coupled to the articulation assembly at a proximal end thereof and extend distally therefrom. The cables are configured to engage an end effector assembly of the surgical instrument at a distal end thereof. The trigger is coupled to the articulation assembly and is selectively moveable from a shipping position to a use position. In the shipping position, the cables are substantially un-tensioned. In the use position, the cables are disposed in an initial tensioned position. In the use position, the trigger is moveable between an unlocked position and a locked position. In the unlocked position, the cables are selectively tensionable to articulate the end effector assembly. In the locked position, the tensions on the cables are maintained to lock the end effector assembly in position.

Articulating surgical device

A surgical access apparatus includes an access member defining a longitudinal axis and having a longitudinal passageway for reception and passage of a surgical object and an access housing mountable to the access member. The access housing includes a diaphragm mounted thereto. The diaphragm is adapted for rotational movement about the longitudinal axis relative to the access housing. The diaphragm defines at least one internal pocket and has a seal assembly disposed within the internal pocket. The seal assembly has an interface seal member adapted for establishing a fluid tight seal about the surgical object. The seal assembly is adapted for selective movement within the pocket about multiple axes in response to manipulation of the surgical object.

Single port device with multi-lumen cap

A specimen retrieval device is provided. The specimen retrieval device includes an applicator. A specimen retrieval pouch operably is disposed within the applicator and deployable therefrom. The specimen retrieval pouch defines a longitudinal axis therethrough and includes a closed bottom portion and an open upper portion. The closed bottom portion includes a plurality of spikes configured to grasp a specimen positioned within the confines closed bottom portion. The upper closed portion includes one or more axial folds that are movable from a folded configuration to an unfolded configuration when a predetermined force is applied to a portion of the specimen retrieval pouch.

A removal pouch that is utilized for removing body tissue from the interior of the body as part of a minimally invasive surgical procedure. The specimen removal pouch includes an elongated body and a gas vent. The elongated body has an interior portion to collect specimen from a body cavity of a patient. The gas vent is configured to allow passage of gas from the interior portion of the elongated body to an external environment during removal of the pouch from within the body cavity of the patient.

An access device includes a body, a first tube, a second tube, and a mechanism. The first and second tubes extend through the body. The mechanism operably couples the first and second tubes such that at least one tube is pivotable about an axis with respect to the other tube. The body may form a substantially fluid-tight seal at the incision. In another embodiment, the access device further includes a third tube extending through the body and the mechanism operably couples the tubes together such that at least two tubes are pivotable about the axis with respect to the remaining tube.
