A seal assembly for use with an access apparatus includes an integral filter and evacuation port for filtering of fluids, e.g., smoke, from an operating site and removing contaminants and/or odor from the fluids for release of the filtered fluids into the ambient atmosphere. The seal assembly may be a separate subassembly or component which is releasably couplable to the access apparatus or may be integral with the access apparatus. The seal assembly defines its own flow path independent of the insufflation mechanism of the cannula assembly, and is capable of filtering fluids even in the presence of a surgical object positioned within the cannula assembly.

A vacuum assisted suction and irrigation system includes a suction and irrigation wand, an irrigation fluid supply, a vacuum source, and a fluid pump. The vacuum source is connected to a suction valve of the suction and irrigation wand to provide suction within the suction and irrigation wand. The irrigation fluid supply is connected to the suction and irrigation wand via the fluid pump to supply pressurized irrigation fluid to the suction and irrigation wand. The vacuum source is connected to the fluid pump to pressurize the irrigation fluid being delivered to the suction and irrigation wand.

A surgical instrument comprising a handle assembly, an elongated shaft, an end effector, a rotation mechanism, and an articulation mechanism is disclosed. The rotation mechanism is disposed in mechanical cooperation with the handle assembly and effects rotation of the end effector about the second longitudinal axis. The articulation mechanism is disposed in mechanical cooperation with the handle assembly and effects movement of the end effector from a first position where the first longitudinal axis is substantially aligned with the second longitudinal axis to a second position where the second longitudinal axis is displaced from the first longitudinal axis. The articulation mechanism comprises a first articulation control disposed in mechanical cooperation with the handle assembly, a first cable and a second cable. Actuation of the first articulation control in a first direction causes the first cable to move distally and causes the second cable to move proximally.

Surgical device with articulation and wrist rotation

A guide member is configured for guiding a suture passer through a cannula and tissue surrounding the cannula to facilitate closure of an opening in tissue. The guide member includes a guide housing and an elongated guide shaft. The guide housing is configured for releasably engaging the guide member with the cannula and defines an entry aperture. The elongated guide shaft extends distally from the guide housing and defines an annular exterior surface. An exit aperture is defined through the annular exterior surface. The guide member defines a lumen extending from the entry aperture, through the guide housing and the elongated guide shaft, to the exit aperture. The entry aperture, lumen, and exit aperture cooperating to define a passageway extending through the guide member.

Devices, systems, and methods for providing surgical access and facilitating closure of surgical access openings

A suture passer includes a handle, an elongated sleeve defining a distal end, an inner shaft slidably disposed within the elongated sleeve, and an end effector assembly disposed at a distal end of the inner shaft. The end effector assembly includes first and second arms, at least one which is movable relative to the other between a spaced-apart position and an approximated position for retaining a portion of a suture therebetween. The inner shaft and elongated sleeve are relatively movable between a first condition, wherein the first and second arms are disposed in the approximated position and the distal end of the elongated sleeve is exposed, a second condition, wherein the first and second arms are disposed in the approximated position and the distal end of the elongated sleeve is shielded, and a third condition, wherein the first and second arms are disposed in the spaced-apart position.

A surgical system includes a cannula and a guide member. The cannula is configured for positioning within an opening in tissue. The cannula includes a base and an elongated tubular member extending distally from the base. The elongated tubular member includes an annular wall defining a longitudinal passageway and defines at least one slot extending through the annular wall. The guide member includes a guide housing configured for releasably engaging the guide member with the cannula and an elongated guide shaft configured for insertion into the elongated tubular member of the cannula. The guide member defines at least one lumen extending therethrough and is configured such that, upon engagement of the guide member with the cannula, the at least one lumen is aligned with the at least one slot of the cannula to define a guide passageway through the guide member and cannula.

A method of surgery includes positioning a cannula within an opening in tissue and inserting a guide member into the cannula. The cannula includes an elongated portion having a base and an elongated tubular member extending distally from the base. The elongated tubular member includes an annular wall defining a longitudinal passageway. At least one slot extends through the annular wall and is disposed in communication with the longitudinal passageway. The guide member includes a guide housing and an elongated guide shaft. The guide member defines at least one lumen extending therethrough. The method further includes releasably engaging the guide housing with the base. Upon engagement of the guide housing with the base, the at least one lumen is aligned with the at least one slot to define a guide passageway through the guide member and cannula.

A laparoscopic surgical system comprising a camera and a base supporting the camera, and a camera insertion tool for inserting the camera into the body cavity. The camera is mountable to a surgical instrument inside the body cavity and releasable from the insertion tool after mounting to the surgical instrument.

Mountable camera for laparoscopic surgery

An illumination system configured to light an anatomical location of a patient is provided. The illumination system includes an interior illumination device positionable and movable within a body cavity of a patient. The interior illumination device is configured to provide a light having a wavelength that is visible to a clinician. The illumination system includes an exterior illumination device operatively coupled to the interior illumination device and positionable and movable about an exterior of a patient. The exterior illumination device is configured to provide a light having a wavelength that is visible to a clinician.

Apparatus and system for performing surgery

An endoscopic stitching device is provided including a handle assembly and an end effector operatively connected to the handle assembly. The handle assembly includes a housing; a trigger operatively supported on the housing; and an actuation cable operatively connected to the trigger and extending from the housing in such a manner that an actuation of the trigger imparts axial translation and rotation to the actuation cable. The end effector includes a tool assembly configured and adapted to perform at least a pair of operations. The actuation cable is operatively connected to the tool assembly in such a manner that the actuation cable is capable of effecting a first operation of the pair of operations of the end effector upon the axial translation thereof and/or effecting a second operation of the pair of operations of the end effector upon the rotation thereof.

Flexible endoscopic stitching devices

A suture deployment system is disclosed including a surgical needle having a flexible suture fixedly attached thereto and a target suture releasably secured to the flexible suture. A collar is positioned between the flexible suture and the target suture and is fixedly secured to the flexible suture. The target suture is releasably secured to the collar is such that the target suture may detach from the collar once a surgical procedure has been completed. The surgical needle is a double pointed surgical needle specifically configured to be manipulated by a surgical suturing apparatus.
