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; and

    a 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.
