A method of dispensing surgical fasteners includes providing an applicator instrument having a housing with a cartridge opening, an elongated shaft extending from the housing, a firing system disposed within the housing for dispensing surgical fasteners, and an actuator for activating the firing system. The method includes forming a surgical opening in tissue, inserting a distal end of the elongated shaft into the surgical opening, inserting a cartridge containing a plurality of first surgical fasteners into the cartridge opening, and engaging the actuator for dispensing one of the first surgical fasteners from the distal end of the elongated shaft. While maintaining the distal end of the elongated shaft inside the surgical opening, the cartridge is removed from the cartridge opening, a second cartridge containing a plurality of second surgical fasteners is inserted into the cartridge opening, and the actuator is engaged for dispensing one of the second surgical fasteners from the distal end of the elongated shaft.

A system for closing a blood vessel includes a housing having a proximal end and a distal end and configured to be held in the hand of a user, an elongate body extending from the distal end of the housing, a distal housing having a proximal end coupled to a distal end of the elongate body and having a cavity including an opening on a side of the distal housing, a lumen passing through the elongate body and terminating at the cavity of the distal housing and configured to couple to a vacuum source, a sensor carried by the distal housing adjacent the cavity and configured for identifying a blood vessel, wherein the lumen is configured to maintain a vacuum within the cavity when a probe having a vessel closure module is inserted within the lumen and the vessel closure module is within the cavity.

A bone marrow aspiration device may include a housing having a proximal end and a distal end; a cannula, insertable into a tissue, extending from the distal end; a ratcheting mechanism coupled to the housing; a reservoir configured to receive a fluid; an actuator operatively coupled to the ratcheting mechanism and to a distal surface of the bone marrow aspiration device such that user-actuation of the actuator actuates the ratcheting mechanism to draw fluid through the cannula, into the housing, and into the reservoir, and retracts the cannula relative to the distal surface.

A tissue retraction system comprising a drive gear coupled to a shaft. The tissue retraction system includes a first plurality of linking members located along a second axis and configured to rotate along the second axis based on contact with the drive gear as the drive gear is rotated. The tissue retraction system includes a linking member selector configured to rotate along the first axis, wherein the linking member selector comprises a cylindrical body integrally formed with a handle. The tissue retraction system includes a right arm assembly configured to move along a first trajectory. The tissue retraction system includes a first retractor blade coupled to the right arm assembly. The tissue retraction system includes a left arm assembly configured to move along a second trajectory. The tissue retraction system includes a second retractor blade coupled to the left arm assembly.

A clipping system includes a pusher element, a holder mounted over an insertion device and clips stacked along a length of the holder. The holder includes a longitudinally channel.

Each clip extends along a curvature defining a tissue-receiving space therewithin and extends about the holder with an exterior surface of the holder holding the clip open with the first and second ends of the clip separated from one another to receive a tissue therein. Each clip is independently deployable from the holder so that, upon release of the clip from the holder, the clip reverts to a closed configuration. In the closed configuration, the first and second ends are moved toward one another to reduce a size of the tissue-receiving space so that tissue is gripped therewithin. The element is mounted over the holder and moved distally along the holder to independently deploy each clips.

A bone closure assembly that includes a buckle and a strap having a first end fixedly attached to the buckle. The strap is configured for looping around bone portions. The bone closure assembly also includes a locking cap removably connected to the buckle. The locking cap is configured for securing the strap within the buckle to secure the bone portions together.

A surgical system comprises at least one implant support including a first implant support that is engageable with a receiver of a first fastener having a shaft fixed with vertebral tissue. At least one adaptor includes a first adaptor extending longitudinally along and being engageable with the first implant support. The first adaptor is rotatable relative to the first implant support to connect the first implant support with a surgical instrument to manipulate the vertebral tissue. Surgical instruments, constructs, implants and methods are disclosed.

A surgical stapling apparatus. Various embodiments include a rotatable elongated body that extends from a rotatable shroud on handle assembly and has a distal end configured for attachment to a disposable loading unit. The apparatus further includes a lockable rotation system for selectively locking the rotatable shroud to prevent rotation thereof about a longitudinal axis.

A surgical access device includes a cannula body and an anchor. The cannula body includes a housing, and an elongated portion extending distally from the housing. The elongated portion defines a longitudinal axis and defines a channel extending therethrough. The anchor is disposed in mechanical cooperation with the elongated portion of the cannula body and is longitudinally translatable relative to the elongated portion. The anchor defines an aperture and includes a ratchet mechanism configured to selectively lock a size of the aperture.

A scalp clip gun, comprising a housing, a magazine, a propulsion mechanism and a locking mechanism. A positioning protrusion is provided at the front end of the housing. A first end of the magazine is provided with a slot, and the slot is cooperatively connected to the positioning protrusion. The propulsion mechanism comprises a trigger, guide rail, a tension spring, a transmission rack, and a driver. The transmission rack is arranged inside the housing and may slide horizontally relative to the housing. The guide rail is arranged in a through-hole of the driver. The driver may move forward relative to the guide rail. The tail end of the guide rail is fixed by means of the locking mechanism and scalp clips are slidingly arranged on the guide rail. The scalp clip gun may quickly and continuously eject the scalp clips.
