摘要：
A surgical device comprises a handle portion including a body defining a stationary handle, a movable trigger, a spindle supported within the body and a barrel assembly slidably positioned about the spindle. The spindle defines a first guide track for slidably receiving a first rack. The first rack is operably connected to a drive member of the surgical device. The barrel assembly includes a first pawl which is selectively movable from a first position engaging the first rack to a second position disengaged from the first rack. The movable trigger is operably associated with the barrel assembly such that movement of the movable trigger effects axial movement of the barrel assembly in relation to the spindle, wherein when the first pawl is in its first position, movement of the barrel assembly in a first axial direction effects corresponding axial movement of the first rack to effect movement of the drive member of the surgical device.
