A surgical clip applier for performing a surgical procedure, the surgical clip applier comprising: a housing; at least one handle pivotably connected to the housing; a channel assembly extending distally from the housing; a jaw assembly including a pair of jaws extending from an end of the channel assembly, opposite the housing, the jaw assembly adapted to accommodate a clip of a plurality of clips loaded in the clip applier and being operable to effect formation of the clip in response to movement of the at least one handle; a dissector bar including a proximal-end portion at least partially slidably supported in the housing, and a distal-end portion extending from the housing and along a length of the channel assembly, the distal-end portion supported on the channel assembly, wherein the dissector bar is actuatable from the housing and includes a proximal position wherein a distal end of the dissector bar is disposed proximal of a distal-most end of the jaw assembly, and at least one distal position wherein the distal end of the dissector bar projects beyond the distal-most end of the jaw assembly; and wherein the dissector bar includes a knob supported near the proximal end thereof, the knob having a neck portion that extends through a slot formed in the housing, characterized in that at least one side wall of the slot of the housing includes a resilient, deformable layer (105; 205; 305) extending along a length thereof, wherein said resilient, deformable layer narrows a width of the slot to have a width dimension that is less than a transverse width dimension of the neck portion of the knob that extends through the slot whereby the dissector bar is held against movement by a frictional force created by the resilient deformable layer (105;205;305) acting on the neck portion of the knob. a housing; at least one handle pivotably connected to the housing; a channel assembly extending distally from the housing; a jaw assembly including a pair of jaws extending from an end of the channel assembly, opposite the housing, the jaw assembly adapted to accommodate a clip of a plurality of clips loaded in the clip applier and being operable to effect formation of the clip in response to movement of the at least one handle; a dissector bar including a proximal-end portion at least partially slidably supported in the housing, and a distal-end portion extending from the housing and along a length of the channel assembly, the distal-end portion supported on the channel assembly, wherein the dissector bar is actuatable from the housing and includes a proximal position wherein a distal end of the dissector bar is disposed proximal of a distal-most end of the jaw assembly, and at least one distal position wherein the distal end of the dissector bar projects beyond the distal-most end of the jaw assembly; and wherein the dissector bar includes a knob supported near the proximal end thereof, the knob having a neck portion that extends through a slot formed in the housing, characterized in that at least one side wall of the slot of the housing includes a resilient, deformable layer (105; 205; 305) extending along a length thereof, wherein said resilient, deformable layer narrows a width of the slot to have a width dimension that is less than a transverse width dimension of the neck portion of the knob that extends through the slot whereby the dissector bar is held against movement by a frictional force created by the resilient deformable layer (105;205;305) acting on the neck portion of the knob.
