Abstract
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.
