摘要： 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.

摘要： 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.

摘要： A surgical stapling device has an elongated body and a removable loading unit and a securing structure for securing the loading unit onto the elongated body. Guiding ramps guide the movement of the loading unit as it is mounted onto the elongated body. A movable yoke secures the loading unit onto the elongated body. A sensor mechanism is engaged by the loading unit and moves with the securing structure. The locking structure has a first position for blocking movement of the sensor mechanism and preventing removal of the loading unit. The locking unit has a second position for allowing the loading unit to be removed from the device.

摘要： A safety handle assembly for use with a surgical instrument having an operative distal end portion is disclosed. The handle assembly includes a handle housing and a drive element movably mounted within the handle housing and connected to an associated operative distal end portion. A drive assembly is positioned within the handle housing and is engageable with the drive element to move the drive element within the handle housing. An actuator is movably mounted on the handle housing and an adjustable force-limiting mechanism is interposed between the drive assembly and the actuator. A force-limiting mechanism releasably connects the actuator to the drive assembly. The force-limiting mechanism is adjustable to preset the force at which the actuator separates or breaks away from the drive assembly.
