    Abstract: A reposable surgical clip applier (10) includes a handle assembly (100) and an endoscopic assembly (200, 300, 400). The handle assembly (100) includes a housing (110) defining a body portion (111) and a fixed handle portion (112) extending from the body portion (111) and a trigger (122) pivotably connected to the housing (110) and movable relative to the fixed handle portion (112) between an un-actuated position and an actuated position. The endoscopic assembly (200, 300, 400) includes a proximal hub (210, 310, 410) configured to be selectively engageable with the housing (110) of the handle assembly (100), an elongated shaft (340) extending distally therefrom, an end effector (350) supported at a distal end of the elongated shaft (340), and an inner drive assembly (320) including a proximal portion (323) and a distal portion (325). The proximal portion (323) may advance within the distal portion (325) upon a blockage of the end effector assembly (350) to permit the trigger (122) to return to an un-actuated position.

    Abstract: A surgical instrument includes a housing, a shaft coupled to and extending distally from the housing, an end effector assembly disposed at a distal end of the shaft, a movable handle coupled to the housing, a drive assembly coupled to the end effector assembly, and an extension mechanism disposed within the housing. The extension mechanism is configured to couple to the shaft and between the movable handle and the drive assembly for moving the shaft and drive assembly between a retracted position and an extended position relative to the housing. The extension mechanism is coupled between the movable handle and the drive assembly in each of the retracted and extended positions such that the movable handle is operable to effect manipulation of the end effector assembly in each of the retracted and extended positions.

    Abstract: A reposable surgical clip applier (100) includes a handle assembly (110) having a housing, a trigger (114) and a drive assembly (120), the drive assembly (120) including a drive rod (122). The reposable surgical clip applier (100) further includes an outer tube assembly (200) disposed on a distal end of the housing and extending distally therefrom, and a clip cartridge assembly (300) selectively connectable to the distal end of the outer tube assembly (200). The clip cartridge assembly (300) includes an outer tube (314) and a pair of jaws (320a) fixedly supported in a distal end thereof, a first jaw pusher (130) in selective engagement with the distal end (122b) of the drive rod (122), a second jaw pusher (132) in selective engagement with the first jaw pusher (130) on a proximal end and the pair of jaws (320a) on a second end, and a plurality of surgical clips (C) disposed within the outer tube (314). A method of assembling a reposable surgical clip applier (100) is also provided.
