Abstract
An endoscopic surgical clip applier includes an endoscopic assembly and a handle assembly. The handle assembly includes a housing, a trigger, a drive bar, and a ratchet assembly. The ratchet assembly includes a first rack, a second rack, a pawl housing engageable with the first rack, and a second pawl engageable with the second rack. In a first position, the pawl housing is in registration with the first rack to prohibit reversal of a direction of movement of the trigger until the pawl housing is disposed beyond a proximal end or a distal end of the first rack. In a second position, the pawl housing is out of registration with the first rack to permit reversal of the movement of the trigger after the second pawl is disposed distally beyond a distal end of the second rack or proximally beyond a proximal end of the second rack.
