A reposable surgical clip applier, comprising:

• a handle assembly including:
• a housing;
• a trigger pivotally supported on and extending from the housing;
• and
• a drive assembly supported within the housing and operatively actuatable by the trigger;
• an endoscopic assembly selectively connectable to the housing of the handle assembly, the endoscopic assembly including:
• a knob assembly configured and adapted for selective connection to the housing of the handle assembly;
• an outer tube connected to and extending from the knob assembly, the outer tube defining a window in a distal end thereof;
• a pair of jaws supported in the window of the outer tube, and extending from the distal end of the outer tube;
• a jaw closure bar slidably supported within the outer tube, the jaw closure bar being operatively connected to the trigger of the handle assembly upon a connection of the endoscopic assembly to the handle assembly;
• and
• a clip pusher bar slidably supported within the outer tube, the clip pusher bar being operatively connected to the drive assembly of the handle assembly upon a connection of the endoscopic assembly to the handle assembly;
• and
• a clip cartridge assembly selectively loadable in and connectable to the window of the endoscopic assembly, the clip cartridge assembly including:
• a clip tray including a plurality of distally oriented, deflectable, resilient fingers projecting from a base wall thereof;
• a cartridge clip pusher bar disposed adjacent the clip tray and slidable relative thereto, the cartridge clip pusher bar including a plurality of distally oriented ramps each terminating in a distal shoulder, a proximal end of the cartridge clip pusher bar being configured for selective connection with the clip pusher bar of the endoscopic assembly;
• and
• a plurality of surgical clips interposed between the clip tray and the cartridge clip pusher bar, wherein a surgical clip is disposed distally of each finger of the clip tray.
