摘要:
A surgical fastener applying apparatus comprising a cartridge body including a plurality of fastener retention slots arranged in a plurality of rows including at least an inner row and an outer row, a plurality of surgical fasteners disposed in inner and outer rows and configured such that a plurality of fasteners disposed in the inner row have a backspan that has a greater height than a backspan of a plurality of surgical fasteners disposed in the outer row, and an anvil having an inner row and an outer row of depressions for forming the fasteners. A plurality of pushers are operably associated with the plurality of surgical fasteners and configured to eject the surgical fasteners toward a respective depression in an anvil for formation thereof such that upon formation, the plurality of surgical fasteners ejected from the inner row provide a greater compressive force to tissue than the plurality of surgical fasteners ejected from the outer row.

A battery pack includes a first cell having top and bottom terminals, a first support disposed on the top terminal, and a second support disposed on the bottom terminal. At least one of the first and second supports may include a rib for maintaining the first cell in place. The first and second supports may lock together. Accordingly, the first support may include a first protrusion, and the second support may include a second protrusion which engages the first protrusion. The battery pack may also include a pad disposed on at least one of the top and bottom terminals.

A surgical instrument including a housing, an endoscopic portion, a drive motor, a drive tube, a firing rod and an end effector is disclosed. The endoscopic portion extends distally from the housing and defines a first longitudinal axis. The drive motor is disposed at least partially within the housing. The drive tube is disposed in mechanical cooperation with the drive motor and is rotatable about a drive tube axis extending through the drive tube. The firing rod is disposed in mechanical cooperation with the drive tube and at least a portion of the firing rod is translatable with respect to the drive tube. The end effector is disposed adjacent a distal portion of the endoscopic portion and is in mechanical cooperation with the firing rod so that the firing rod drives a surgical function of the end effector.

A surgical instrument including a handle assembly, a first endoscopic portion, a motor, and a first end effector is disclosed. The first endoscopic portion is selectively connectable to a distal portion of the handle assembly and defines a longitudinal axis. The first endoscopic portion includes a housing adjacent its proximal portion and includes an actuation member. The motor is disposed in mechanical cooperation with the housing of the first endoscopic portion and is operatively connected to the actuation member for moving the actuation member substantially along the longitudinal axis. The first end effector is selectively connectable to a distal portion of the first endoscopic portion and is configured to perform a first stapling function.
摘要:
A surgical fastener applying apparatus comprising a fastener supporting portion and a retainer supporting portion. The fastener supporting portion includes a first row of first surgical fasteners and a second row of second surgical fasteners. The retainer supporting portion includes a first row of first retainers and a second row of second retainers, the first fasteners engagable with the first retainers and the second fasteners engagable with the second retainers. The fasteners and retainers are configured so when engaged a first distance between at least one of the first fastener backspans and respective first retainer backspan is different than a second distance between at least one of the second fastener backspans and respective second retainer backspan.

摘要:
A modular power tool (10) incorporates a modular drive system (14, 18, 22) and modular handle set (12) that is reversible or use with both a left and right hand configuration. The modular drive system (14, 18, 22) and handle set (12) of the modular power tool (10) of this invention reduces the need for derivative circular saw designs by introducing common components.
