Patent number: 8424739Abstract: A surgical stapling device is disclosed which includes a handle assembly, an endoscopic body portion and a tool assembly. The tool assembly is rotatably and pivotally supported on a distal end of the endoscopic body portion. A tool assembly rotation mechanism is provided which includes a rotation knob, a substantially rigid tube and a flexible member interconnecting the rigid tube to the tool assembly. The substantially rigid tube translates rotation of the rotation knob to rotation of the flexible member and provides a channel for passage of other components of the surgical stapling device.Type: GrantFiled: September 15, 2011Date of Patent: April 23, 2013Assignee: Covidien LPInventors: David C.

Patent number: 8418908Abstract: Disclosed is a surgical stapling apparatus and method of use that includes a cartridge assembly which is capable of being reloaded during a surgical procedure without being removed from the surgical site. This allows a surgeon to continue a surgical operation without withdrawing or removing the surgical stapler for reloading and thus reduces the length of the surgery while allowing the physician to concentrate solely on the surgical procedure rather than dividing attention between the surgical procedure and reloading of the surgical stapler. The surgical stapling apparatus includes an elongate member having a plurality of fasteners arranged in a plurality of longitudinally extending rows which is longitudinally translatable through the cartridge to position the plurality of fasteners relative to a plurality of retention slots extending through an upper surface of the cartridge.Type: GrantFiled: October 26, 2011Date of Patent: April 16, 2013Assignee: Covidien LPInventor: John W. Beardsley

Patent number: 8408442Abstract: A surgical device comprising an anvil, a cartridge assembly, a dynamic clamping member, a clamp ring and a drive mechanism is disclosed. The cartridge assembly is configured to house a plurality of fasteners at least partially therein. The anvil and cartridge assembly are movable in relation to each other between open and approximated positions. The dynamic clamping member is slidably positioned to translate at least partially through the cartridge assembly to eject fasteners therefrom. The dynamic clamping member engages the anvil and the cartridge assembly. The clamp ring is movable from a retracted position to an advanced position at least partially encircling proximal portions of the anvil and cartridge assembly for preventing a gap between proximal portions of the anvil and cartridge assembly from exceeding a predetermined distance. The drive mechanism includes a single actuator for driving both the clamp ring and the dynamic clamping member.Type: GrantFiled: September 26, 2011Date of Patent: April 2, 2013Assignee: Covidien LPInventors: David C.
