The clamp arm comprises a movable jaw member electrically coupled to another output of the RF generator. The electrical switch is operable to cause the surgical instrument to deliver electrical current from the RF generator to the movable jaw member for a first period, and to cause the surgical instrument to deliver ultrasonic energy to the ultrasonic blade for a second period.

Ultrasonic and electrosurgical devices

A surgical instrument includes a first power source and a second power source. The first power source is configured to deliver power to a surgical instrument at a first rate of discharge. The second power source is configured to deliver power to the first power source at a second rate of discharge. The first power source and the second power source are positioned within the surgical instrument. The first power source and the second power source are further configured to communicate with a control module. The control module may rely on power from the first power source to drive an end effector of the surgical instrument. The end effector may comprise a harmonic/ultrasonic blade, RF electrosurgical electrodes, powered cutting/stapling features, and/or various other types of components.

Surgical instrument with charging devices

A surgical instrument comprising an elongate shaft assembly operably supporting a circular surgical staple cartridge in a distal end thereof and a plurality of arcuate tissue acquisition members pivotally attached to the elongate shaft assembly and configured to be selectively radially deployable from a first position wherein the plurality of arcuate tissue acquisition members cooperate to form a continuous ring defining a continuous outer ring diameter and a second deployed position wherein each arcuate tissue acquisition member extends radially outward from the elongate shaft assembly is disclosed. The surgical instrument further comprises means for selectively deploying the plurality of arcuate tissue acquisition members between the first position and the second deployed position, a tissue cutting member comprising two diametrically opposed ends forming a plurality of tissue cutting edges, and means for selectively rotating the tissue cutting member relative to the plurality of arcuate tissue acquisition members.

Circular surgical fastening devices with tissue acquisition arrangements

A surgical instrument is separable into a transducer unit and a lower body portion. The lower body portion includes a waveguide and a casing. The transducer unit includes a transducer and a geared mechanism operable to couple the transducer to the waveguide. In some versions the geared mechanism includes bevel gears coupled to a rack and pinion such that linear motion may be used to rotatably couple a transducer to a waveguide. The rack gear may further include a handle extending out of the transducer unit casing to be actuatable by a user. The rack gear may also be flexible or rigid. In other versions, the bevel gears may be coupled to a threaded shaft that is operable to translate the transducer into the waveguide to form an interference fit. The transducer unit may also include a slide lock mechanism to couple to the casing of the lower body portion.

Gear driven coupling between ultrasonic transducer and waveguide in surgical instrument

An apparatus for aseptic insertion includes a container, a first cover, and a second cover. The container includes a first compartment, a second compartment, and a detachable wall disposed between the first compartment and the second compartment. The first cover is sized and configured to attach to the first compartment and the second cover is sized and configured to attach to the container. The detachable wall may defined by a top portion, a portion of a first distal wall of the first compartment, and a portion of a second proximal wall of the second compartment. The detachable wall may be removably attached to the first cover by the top portion of the detachable wall.

Sterile package system for medical device

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 transducer structure affixed to a longitudinally elongated, generally planar, single crystal or polycrystalline material waveguide.

Ultrasonic surgical apparatus with silicon waveguide

A surgical apparatus includes an end effector having an ultrasonic blade, a clamp arm, and a clamp pad. The end effector applies ultrasonic energy at the blade. The clamp arm pivots relative to the blade. The clamp pad is positioned on the clamp arm adjacent to the blade. The clamp arm includes a latching feature to retain the clamp pad relative to the clamp arm to prevent the clamp pad from moving laterally, longitudinally, and perpendicularly relative to the clamp arm.

When closed, the end piece covers the aperture. In another version, the aperture is configured to receive a data card and battery pack assembly. Information is readable from and to the data card to measure a number of minutes the instrument was used during a procedure. Such information is communicated via wired or wireless communication to another device to determine a payment for the number of minutes used. Minutes are buyable from the device and writable onto the data card prior to insertion of the card into the instrument. In another version, a testing sequence is used in saline or via a tissue proxy to test the functionality of an instrument prior to a procedure.
