An optical obturator apparatus includes an obturator sleeve defining a longitudinal axis and having a longitudinal bore for receiving surgical instrumentation and a transparent window mounted to the obturator sleeve and being dimensioned and configured to pass through tissue. The transparent window is mounted for movement between a first position in general alignment with the longitudinal axis of the obturator sleeve and a second position radially displaced from the longitudinal axis to thereby expose the longitudinal bore of the obturator sleeve to permit passage of the surgical instrumentation. The transparent window may include a cutting blade, or alternatively two cutting blades, adapted to penetrate tissue.

Optical obturator

A mesh deployment device having separate mesh deployment and actuation units is provided. A mesh deployment device includes an actuation unit and a mesh deployment unit configured to be releasably secured to the actuation unit. When the mesh deployment unit is secured to the actuation unit, a first actuation of the actuation unit moves the mesh deployment unit from an expanded condition to a collapsed condition and a second actuation of the actuation unit moves the mesh deployment unit from the collapsed condition to the expanded condition. The mesh deployment device may further include a mesh releasably secured to the mesh deployment unit. A third actuation of the actuation unit may release the mesh from the mesh deployment unit. Also provided is a kit including multiple mesh deployment units.

Mesh deployment devices and kits

A surgical stapling device for sequentially applying a plurality of fasteners to body tissue and simultaneously incising tissue is provided. The surgical stapling device is adapted to receive disposable loading units having staples in linear rows whose length can be between about 30 mm and 60 mm. The disposable loading unit includes a proximal body portion, a mounting assembly and a tool assembly. The mounting assembly is secured to the proximal end of the tool assembly and pivotally mounted about a pivot axis to the distal end of the proximal body portion. A support member or blow-out plate assembly is positioned on opposite sides of the pivot axis and extends between the proximal body portion and the mounting assembly.

Surgical stapling device

A surgical fastener applier including a housing containing a compartment, an elongated member extending distally from the housing, first and second jaws and a firing mechanism. The firing mechanism is movable between a first position and a second position to effect firing of fasteners into the tissue clamped between the first and second jaws. A power pack is removably loadable into the compartment, the power pack having a motor and an engagement member removably engageable with the firing mechanism within the compartment when the power pack is loaded into the compartment to effect movement of the firing mechanism. An interchangeable battery pack is removably loadable into the power pack for powering the motor. Bearings restrict axial and radial movement of the firing and articulation assembly in the power pack.

A gastric tube for use in a bariatric surgical procedure includes an elongate tube and a movable component supported on an outer surface of the elongate tube. The elongate tube has a non-circular cross section along at least a portion of a length of the elongate tube. The movable component is movable between an unexpanded configuration and an expanded configuration. In the unexpanded configuration, the movable component is disposed in abutting engagement with the outer surface of the elongate tube. In the expanded configuration, the movable component bows outwardly from the outer surface of the elongate tube.

Gastric tubes and methods of use

The present disclosure is directed to a testing systems and methods for testing a powered surgical instrument. The powered surgical instrument includes a processor configured to control operation of the powered surgical instrument, a memory configured to store a tissue compression program, a reload configured to clamp tissue, a motor configured to control the reload to apply a compressive force to the tissue by the reload, and at least one sensor configured to measure a current draw on the motor. The processor executes the simulation program to measure the current draw on the motor through a nominal thickness firing and the measured current draw is used to adjust the tissue compression program.

System and method of using simulation reload to optimize staple formation

The present disclosure relates to an insertion device including a shaft with a head supported on a distal end thereof. The shaft includes a proximal end with an engagement member that is configured to frictionally engage a distal end of a surgical fastening apparatus such that an interference fit is created therebetween to facilitate selective detachment of the insertion device from the surgical fastening apparatus. The head has an atraumatic configuration, and is dimensioned to be received in a body orifice.

Insertion aid with interference fit

A surgical stapling device includes a body portion, a tool assembly, a mounting assembly, a retaining member, and an articulation member that is coupled to the tool assembly for articulating the tool assembly in relation to the body portion. The retaining member is engaged with the articulation member to prevent movement of the articulation member until the articulation member is actuated.

A surgical fastener applier is disclosed and includes a handle portion, a tubular member extending from the handle portion and defining a longitudinal axis, a drive member rotatably supported in the tubular member and in the handle portion, and a plurality of fasteners. The drive member is configured to rotate while in a deflected condition with respect to the longitudinal axis. The drive member includes a proximal portion, a central portion, and a distal portion, the central portion being relatively more flexible configuration as compared to at least one of the proximal portion and the distal portion. The plurality of fasteners is disposed within the tubular member and is configured to engage a portion of the drive member such that rotational motion of the drive member causes distal advancement of at least one fastener of the plurality of fasteners through the tubular member.

Flex cable and spring-loaded tube for tacking device

A surgical instrument including a handle assembly, an elongated body portion, a head portion and an elongated channel. The elongated body portion extends distally from the handle assembly. The head portion is disposed adjacent a distal end of the elongated body portion and includes an anvil assembly and a shell assembly. The elongated channel includes a proximal opening and a distal opening. The proximal opening is disposed distally of a proximalmost end of the handle assembly and proximally of the shell assembly. The distal opening is disposed on the shell assembly.
