A surgical clip applier is provided including a housing; at least one handle pivotably connected to the housing; a channel assembly extending distally from the housing; a plurality of clips loaded in the clip carrier; a drive channel translatably supported in the housing and the channel assembly, the drive channel being translated upon actuation of the at least one handle; and a counter mechanism supported in the housing, the counter mechanism including indicia visible through the housing, wherein the indicia corresponds to a quantity of clips loaded in the clip applier, wherein the indicia decrements upon each firing of the clip applier resulting in a reduction in the quantity of clips remaining of the plurality of clips.
1. A surgical clip applier, comprising: a housing;at least one handle pivotably connected to the housing;a channel assembly extending distally from the housing;a plurality of clips loaded in a clip carrier;a drive channel translatably supported in the housing and the channel assembly, the drive chan
1. A surgical clip applier, comprising: a housing;at least one handle pivotably connected to the housing;a channel assembly extending distally from the housing;a plurality of clips loaded in a clip carrier;a drive channel translatably supported in the housing and the channel assembly, the drive channel being translated upon actuation of the at least one handle; anda counter mechanism supported in the housing and including: a counter dial rotatably supported in the housing;a counter clutch operatively connected to the drive channel, the counter clutch concentrically and rotatably nested in a bore defined in the counter dial such that rotation of the counter clutch in a first direction results in rotation of the counter dial in the first direction, and rotation of the counter clutch in a second direction results in no rotation of the counter dial, wherein translation of the drive channel in a first direction relative to the counter mechanism directly causes the counter clutch to rotate in the first direction, and translation of the drive channel in a second direction relative to the counter mechanism directly causes the counter clutch to rotate in the second direction;indicia disposed on the counter dial and visible through the housing, wherein the indicia corresponds to a quantity of clips loaded in the clip applier, wherein the indicia decrements upon each firing of the clip applier resulting in a reduction in the quantity of clips remaining of the plurality of clips. 2. The clip applier according to claim 1, wherein the counter clutch includes a uni-directional clutch member configured to rotate the counter dial in a single direction. 3. The clip applier according to claim 1, wherein the counter mechanism includes a latch member operatively engaged with the counter dial, wherein the latch member permits rotation of the counter dial in the first direction and inhibits rotation of the counter mechanism in a direction opposite to the first direction. 4. The clip applier according to claim 3, wherein the counter dial includes a plurality of grooves formed in an outer periphery thereof, and the latch member includes a resilient finger biased into engagement with the plurality of grooves of the counter dial. 5. The clip applier according to claim 1, wherein the counter clutch includes at least one resilient finger extending therefrom for engagement with uni-directional teeth formed in a perimetrical surface of the bore of the counter dial. 6. The clip applier according to claim 5, wherein the drive channel defines an angled slot therein, and wherein the counter clutch includes a clutch pin extending from a surface thereof and slidably disposed in the angled slot of the drive channel, wherein translation of the drive channel in the first direction relative to the counter mechanism causes the clutch pin to be cammed by the angled slot thereof thereby causing the counter clutch to rotate in the first direction, and translation of the drive channel in the second direction relative to the counter mechanism causes the clutch pin to be cammed by the angled slot thereof thereby causing the counter clutch to rotate in the second direction. 7. The clip applier according to claim 6, wherein the counter mechanism includes a latch member operatively engaged with the counter dial, wherein the latch member permits rotation of the counter dial in the first direction and inhibits rotation of the counter mechanism in a direction opposite to the first direction. 8. The clip applier according to claim 7, wherein the counter dial includes a plurality of grooves formed in an outer periphery thereof, and the latch member includes a resilient finger biased into engagement with the plurality of grooves of the counter dial. 9. The clip applier according to claim 1, wherein the counter mechanism includes: a lock out groove formed in an outer perimetrical edge of the counter dial; anda lock out supported in the housing and biased such that a first catch thereof engages against the outer perimetrical edge of the counter dial,wherein as the counter dial is rotated in the first direction and the lock out groove of the counter dial is brought into registration with the first catch of the lock out, the first catch of the lock out moves into and engages the lock out groove to inhibit further rotation of the counter dial in the first direction. 10. The clip applier according to claim 9, wherein the lock out includes a second catch, and wherein the second catch moves into a path of a translating member of the clip applier when the first catch of the lock out is moved into the lock out groove of the counter dial, thereby inhibiting a translation of the translating member of the clip applier. 11. The clip applier according to claim 10, wherein the lock out groove of the counter dial moves into registration with the first catch of the lock out when a final clip of the plurality of clips has been fired. 12. The clip applier according to claim 11, wherein the lock out groove of the counter dial is associated with the indicia on the counter mechanism indicating that the final clip has been fired. 13. The clip applier according to claim 12, wherein the indicia on the counter mechanism indicating that the final clip of the plurality of clip has been fired is represented by a number “zero”. 14. The clip applier according to claim 10, further comprising a ratchet mechanism including: a ratchet pawl pivotably supported in the housing; anda rack member provided on the translating member, wherein the rack member is in operative registration with the ratchet pawl, and wherein the rack member translates across the ratchet pawl as the translating member translates. 15. The clip applier according to claim 14, wherein the ratchet mechanism is prevented from re-setting when the rack member has not completed a full translation. 16. A surgical clip applier, comprising: a housing;at least one handle pivotably connected to the housing;a channel assembly extending distally from the housing;a plurality of clips loaded in a clip carrier;a drive channel translatably supported in the housing and the channel assembly, the drive channel being translated upon actuation of the at least one handle; anda counter mechanism supported in the housing, the counter mechanism including indicia visible through the housing, wherein the indicia corresponds to a quantity of clips loaded in the clip applier, wherein the indicia decrements upon each firing of the clip applier resulting in a reduction in the quantity of clips remaining of the plurality of clips, the counter mechanism including a counter clutch concentrically and rotatably nested in a bore defined in the counter mechanism, the counter clutch being operatively connected to the drive channel wherein translation of the drive channel in a first direction relative to the counter mechanism directly causes the counter clutch to pivot in a first direction, and translation of the drive channel in a second direction relative to the counter mechanism directly causes the counter clutch to pivot in a second direction. 17. The clip applier according to claim 16, wherein the counter mechanism is rotatably supported in the housing and the counter clutch is configured to rotate the counter mechanism in a single direction to decrement the indicia upon a pivot thereof. 18. The clip applier according to claim 16, wherein the counter mechanism includes a counter dial rotatably supported in the housing and including the indicia thereon, the counter clutch being nested concentrically within the counter dial and the counter mechanism. 19. The clip applier according to claim 18, wherein pivoting the counter clutch in the first direction results in rotation of the counter dial in the first direction, and pivoting the counter clutch in the second direction results in no rotation of the counter dial.
