| 20080217375 | SURGICAL STAPLING DEVICE WITH DISSECTING TIP - A dissecting tip is provided for use with a surgical stapler or instrument. In one embodiment, the dissecting tip is secured to the end effector of the surgical instrument, e.g., to the cartridge assembly. The dissecting tip extends distally from the end effector and is configured to dissect or separate target tissue from certain tissue, e.g., adherent, connective, joined or other tissue. | 09-11-2008 |
| 20080269793 | Surgical Stapling Device with Dissecting Tip - A dissecting tip is provided for use with a surgical stapler or instrument. In one embodiment, the dissecting tip is secured to the end effector of a surgical stapler, e.g., to the anvil assembly or cartridge assembly. The dissecting tip extends distally from the end effector and is configured to dissect or separate target tissue from certain tissue, e.g., adherent, connective, joined or other tissue. | 10-30-2008 |
| 20090008425 | Angled surgical fastener apparatus - A surgical fastening apparatus includes a handle, an elongated member extending distally from the handle and a fastener applier and anvil head disposed at the distal end of the elongated member. The elongated member defines a distal offset end portion upon which the fastener applier and the anvil head are mounted. The offset end portion is angularly oriented with respect to the axis of the instrument at a predetermined fixed angle (e.g., either 45°, 60° and 75° relative to the axis of the instrument) thereby positioning the fastener applier and the anvil head at the fixed angle This feature facilitates positioning of the tissue with respect to the instrument and enhances visual access to the tissue when appropriately disposed within the fastener applier and the anvil head. Various mechanisms for effectuating the clamping of the tissue between the fastener holder and anvil, and the firing of the instrument are disclosed. | 01-08-2009 |
| 20090236395 | Rotating Knob Locking Mechanism For Surgical Stapling Device - A surgical stapling device having a rotating knob locking mechanism, and a method of using the surgical stapling device is disclosed. The surgical stapling device includes a housing, an actuation member, an elongated body portion rotatably supported on the housing, and a locking mechanism for preventing the rotation of the elongate body portion, the locking mechanism being automatically engaged upon actuation of the actuation member. The stapling device further includes a knob for rotating the elongated body portion. The locking mechanism includes a pivotably mounted member configured to engage the knob. The stapling device may further include an articulating tool assembly and an articulation lever for articulating the tool assembly. The articulation lever may be disposed on the knob for rotating the elongated body portion. | 09-24-2009 |
| 20100072258 | Surgical Instrument And Loading Unit For Use Therewith - A surgical instrument is disclosed. The surgical instrument includes a handle assembly, a drive assembly, an endoscopic portion, a pair of jaw members, a dynamic clamping member, and a tissue stop. The drive assembly is disposed in mechanical cooperation with a movable handle of the handle assembly. The endoscopic portion defines a first longitudinal axis. The jaw members are each longitudinally curved with respect to the longitudinal axis. The dynamic clamping member is disposed in mechanical cooperation with a distal portion of the drive assembly and includes an upper beam, a lower beam, and a vertical beam having a cutting edge on a distal portion thereof. At least a portion of the dynamic clamping member is longitudinally curved with respect to the longitudinal axis. The tissue stop is disposed adjacent a distal portion of the first jaw member and configured to impede tissue from distally escaping the jaw members. | 03-25-2010 |
| 20100096432 | SURGICAL STAPLING APPARATUS WITH LOCKING MECHANISM - The present disclosure provides for a loading unit for use with and/or supportable on a distal end of a surgical stapling apparatus. The loading unit includes a housing portion including a distal end and a proximal end, a drive assembly slidably supported within the housing portion of the loading unit, and a locking mechanism pivotally supported on the housing portion of the loading unit, the locking mechanism having a first position wherein the locking mechanism engages a portion of the drive assembly and maintains the position, preferably the axial position, of the drive assembly relative to the housing portion of the loading unit, and the locking mechanism having a second position wherein the locking mechanism disengages the drive assembly and enables the drive assembly to move relative to the housing portion. | 04-22-2010 |
| 20100301097 | Loading Unit Having Drive Assembly Locking Mechanism - A disposable loading unit is provided which includes a tool assembly and a body portion. A drive assembly is movably positioned at least partly within the body portion and is operably associated with the tool assembly to operate the tool assembly. A locking mechanism is provided for maintaining the drive assembly in a prefired position prior to and during attachment of a DLU to a surgical instrument. The locking mechanism includes a locking member and a locking member actuator. The locking member actuator is movable to move the locking member to an unlocked position in response to linear insertion of an insertion tip of the DLU into a surgical instrument. | 12-02-2010 |
| 20110062213 | Surgical Stapling Device with Dissecting Tip - A dissecting tip is provided for use with a surgical stapler or instrument. In one embodiment, the dissecting tip is secured to the end effector of the surgical instrument, e.g., to the cartridge assembly. The dissecting tip extends distally from the end effector and is configured to dissect or separate target tissue from certain tissue, e.g., adherent, connective, joined or other tissue. | 03-17-2011 |
