A surgical clip applier (100), comprising: a housing (104)； at least one handle (106) pivotably connected to the housing (104)； a channel assembly (108) extending distally from the housing (104)； a plurality of clips (C) loaded in the clip carrier (170)； a drive channel (140) translatably supported in the housing (104) and the channel assembly (108), the drive channel (140) being translated upon actuation of the at least one handle (106)； and a counter mechanism (190) supported in the housing (104), the counter mechanism (190) including indicia visible through the housing (104), wherein the indicia corresponds to a quantity of clips (C) loaded in the clip applier (100), wherein the indicia decrements upon each firing of the clip applier (100) resulting in a reduction in the quantity of clips (C) remaining of the plurality of clips (C), and characterized in that: the counter mechanism includes: a counter dial (192) defining a lock out groove (192g) formed in an outer perimetrical edge thereof； a lock out (146) supported in the housing (104), the lock out (146) being biased such that a first catch (146b) thereof engages against the outer perimetrical edge of the counter dial (192), wherein as the counter dial (192) is rotated and the lock out groove (192g) of the counter dial (192) is brought into registration with the first catch (146b) of the lock out (146), the first catch (146b) of the lock out (146) is urged into the lock out groove (192g) thereby preventing a rotation of the counter dial (192) in an opposite direction； and the lock out (146) further includes a second catch (146c), and wherein the second catch (146c) moves into a path of a translating member (141) when the first catch (146b) of the lock out (146) is moved into the lock out groove (192g) of the counter dial (192), thereby inhibiting a translation of the translating member (141) of the clip applier (100).
