Stabilizer 162 includes a distal tab 162 a configured to engage distal window 160 e of pusher bar 160, an elongate window 162 b defined therein at a location to substantially overlie and be in registration with proximal window 160 d formed in pusher bar 160. For a more detailed discussion of stabilizer 162, please refer to commonly owned U.S. Provisional Application No. 61/091,467, filed on Aug. 25, 2008, entitled “Surgical Clip Applier” and U.S. Provisional Application No. 61/091,485, filed on Aug. 25, 2008, entitled “Surgical Clip Applier and Method of Assembly,” the entire contents of each of which being incorporated herein by reference in its entirety.
As seen in FIG. 3, clip applier 100 further includes a motion multiplier system having a bell crank gear 154 pivotally supported in housing 104 and an accelerator housing 156 slidably supported in housing 104. For a more detailed discussion of bell crank gear 154, please refer to commonly owned U.S. Provisional Application No. 61/091,467, filed on Aug. 25, 2008, entitled “Surgical Clip Applier” and U.S. Provisional Application No. 61/091,485, filed on Aug. 25, 2008, entitled “Surgical Clip Applier and Method of Assembly,” the entire contents of each of which being incorporated herein by reference in its entirety.
With continued reference to FIG. 3, accelerator rack 156 of motion multiplier system includes a base wall 156 a defining an elongate, longitudinally extending slot 156 b formed therein, for slidable receipt of pivot pin 154 a of bell crank gear 154. Accelerator rack 156 includes a side wall 156 c projecting in opposite directions from a side edge of base wall 156 a, and a gear rack 156 d formed in side wall 156 c and in registration or alignment with slot 156 b of base wall 156 a. Gear rack 156 d is configured for engagement with gear teeth 154 g of spur gear 154 d of bell crank gear 154.
Clip applier 100 further includes a clip carrier 170 disposed within channel assembly 108 and beneath pusher bar 160. Clip carrier 170 is generally a box-like structure having an upper wall 170 a, a pair of side walls 170 b and a lower wall 170 c defining a channel 170 d therethrough. Clip carrier 170 includes a plurality of spaced apart windows 172 formed in upper wall 170 a and extending longitudinally along a length thereof. Clip carrier 170 includes an elongate window 170 e formed in lower wall 170 c and extending longitudinally along a length thereof.
As seen in FIGS. 3, 6, and 14, clip applier 100 includes a wedge plate motion reversing mechanism, in the form of a pivot arm 179, pivotally supported in lower housing half 104 b of housing 104 for transmitting the translation of drive channel 140 to a reverse translation of wedge plate 180.
As seen in FIGS. 3 and 6, clip applier 100 further includes an audible/tactile indicator 148 connected to drive channel 140 via drive pin 124. Indicator 148 includes a resilient finger 148 a and a pair of bosses 148 b. In use, as clip applier 100 is actuated and drive channel 140 is reciprocated, first resilient finger 148 a of indicator 148 interacts with corresponding complementary structure or ledge 149 provided in clip applier 100 to create an audible and/or a tactile feedback to the user. Bosses 148 b of indicator 148 ride within channel 104 e formed in upper housing half 104 a and provide support to indicator 148 to prevent indicator 148 from rotating.
As seen in FIGS. 1-3, and 6, clip applier 100 further includes a counter mechanism 190 supported in housing 104 of handle assembly 102. Counter mechanism 190 includes a display 192, a processor 194, and an energy source 198 in the form of a battery or the like. Display 192 is a liquid crystal display that displays one or more operating parameters of clip applier 100 to the surgeon. The operating parameter displayed may be an amount or number of remaining clips, a number of clips that have been used, a position parameter, a surgical time of usage, or any other parameter of the procedure. For a more detailed discussion of counter mechanism 190, please refer to commonly owned U.S. Provisional Application No. 61/091,467, filed on Aug. 25, 2008, entitled “Surgical Clip Applier” and U.S. Provisional Application No. 61/091,485, filed on Aug. 25, 2008, entitled “Surgical Clip Applier and Method of Assembly,” the entire contents of each of which being incorporated herein by reference in its entirety.
As seen in FIG. 2, clip applier 100 includes a shipping wedge 200 supported on housing 104 and interposed between handles 106. Shipping wedge 200 functions to maintain handles 106 spaced apart or un-squeezed during a shipment and/or storage of clip applier 100. Shipping wedge 200 is connected to tab 192 a of counter mechanism 190, such that in order for an end user to use clip applier 100, the end user must remove shipping wedge 200 thereby also removing tab 192 a to activate counter mechanism 190. For a more detailed discussion of shipping wedge 200, please refer to commonly owned U.S. Provisional Application No. 61/091,467, filed on Aug. 25, 2008, entitled “Surgical Clip Applier” and U.S. Provisional Application No. 61/091,485, filed on Aug. 25, 2008, entitled “Surgical Clip Applier and Method of Assembly,” the entire contents of each of which being incorporated herein by reference in its entirety.
