The surgical stapler includes a cartridge housing a plurality of fasteners, an anvil mounted adjacent the cartridge, a drive assembly configured to translate through the cartridge to eject the fasteners therefrom, and at least one visual indicator configured to indicate a position of the drive assembly, wherein the visual indicator includes a material that provides an optical contrast with at least one of the cartridge and the anvil.

One handed stapler

The present disclosure is directed to a surgical instrument, which includes a handle assembly and an elongate member having two jaw members. The second jaw member is movable in relation to the first jaw member between an open position and a closed position. The first jaw member is supported by the elongate body and contains a plurality of fasteners. The elongate member extends distally from the handle assembly and defines both a longitudinal axis and a distal portion. A switch is placed about the handle assembly to allow the handle assembly to operate in multiple modes.

Detachable buttress material retention systems for use with a surgical stapling device

Systems of releasably connecting staple line buttress material to the jaws of a surgical stapling instrument are provided. The systems include retainers configured to engage the buttress material and releasably retain the buttress material on the jaws of the surgical stapling instrument prior to stapling tissue. In certain embodiments, the retainers remain with the jaws of the instrument after stapling of tissue. In alternative embodiments, the retainers remain with the buttress material after being stapled to tissue.

Surgical stapling device

The present disclosure describes a surgical device with a body portion defining a longitudinal axis, a tool assembly including an anvil, a cartridge assembly housing a plurality of staples, a dynamic clamping member movable relative to the tool assembly to eject the staples, and an articulation and firing actuator extending at least partially through the body portion and the tool assembly. The tool assembly is pivotally attached to the body portion for movement from a position aligned with the longitudinal axis to a position oriented at an angle thereto. The articulation and firing actuator extends at least partially through the body portion and the tool assembly, is operably associated with the dynamic clamping member and the tool assembly, and is movable in relation thereto to selectively pivot the tool assembly relative to the body portion and move the dynamic clamping member relative to the tool assembly to eject the staples.

Tissue fastening system for a medical device

A surgical fastening device includes a handle assembly having a stationary handle and a movable handle and an elongated member extending distally from the handle portion. The elongated member includes a distal end portion. The device also includes a pair of firing rods operably coupled with the movable handle and movable between a proximal position and a distal position. A tool assembly has a plurality of helical fasteners supported therein and includes a pair of opposing jaw members. At least one of the jaw members is movable in relation to the other jaw member between spaced and approximated positions. The jaw members are configured to form a pair of radial channels when the jaw members are in the approximated position. The firing rods are configured to advance helical fasteners through at least one radial channel and into tissue upon movement from the proximal position to the distal position.

Hand tool machine having an oscillatory drive

A hand tool is disclosed, comprising a housing, a motor shaft being coupled to a drive motor, a working spindle configured for being driven rotatingly oscillatingly about its longitudinal axis, and a coupling element being driven rotatingly by the motor shaft and having a closed guide surface that revolves around the motor shaft. The guide surface is coupled, via transmission means, to at least one driver for driving the latter. The at least one driver is arranged movably relative to the working spindle and engages the working spindle at a circumferential region thereof for driving the latter rotatingly oscillatingly.

Ultrasonic surgical apparatus with silicon waveguide

Ultrasound surgical apparatus are disclosed, including: medical ultrasound handpieces with proximally mounted ultrasound radiators configured to create a distally-focused beam of ultrasound energy, in combination with distal guide members for control of focal point depth; medical ultrasound handpieces with proximally mounted ultrasound radiators configured to create a distally-focused beam of ultrasound energy, in combination with distal rolling members for manipulability and control of focal point depth; medical ultrasound handpiece assemblies with coupled end effectors providing a probe with a probe dilation region configured to have an average outside diameter that is equal to or greater than the average outside diameter of a probe tip and neck; as well as junctions to an ultrasonically inactive probe sheath; medical ultrasound handpiece assemblies with coupled end effectors having positionable, ultrasonically inactive probe sheath ends slidably operable to both cover and expose at least a probe tip; and ultrasound transducer cores including a transducing structure affixed to a longitudinally elongated, generally planar, single crystal or polycrystalline material waveguide.

Insertion device for an insertion set and method of using the same

An insertion device and insertion set. The insertion device for inserting at least a portion of at least one piercing member of an insertion set through the skin of a patient includes a device housing, a carrier body and a driver. The carrier body is slidably received within the device housing for movement between an advanced position and a retracted position. The carrier body also includes a receiving structure to support the insertion set in a position with the at least one piercing member oriented for insertion through the skin of the patient at a predetermined or variable angle relative to the skin of the patient upon movement of the carrier body from the retracted position to the advanced position. The driver is operatively coupled between the device housing and the carrier body to urge the carrier body from the retracted position toward the advanced position to place at least a portion of the at least one piercing member of the insertion set thorough the skin of the patient to install the insertion set to the patient. The receiving structure of the carrier body is removable from the insertion set while maintaining the installation of the insertion set to the patient.
