ENDOSCOPIC SURGICAL CLIP APPLIER INCLUDING COUNTER ASSEMBLY
First Claim
1. A surgical clip applier, comprising:
- a handle assembly;
an elongated tubular member extending distally from the handle assembly;
a rack bar translatably supported in the handle assembly;
a counter assembly supported in the handle assembly and including;
a counting mechanism positioned to rotate within the handle assembly, the counting mechanism including indicia visible through the handle assembly;
a ratchet mechanism rotationally coupled to the counting mechanism, the ratchet mechanism prohibiting multidirectional rotation of the counting mechanism; and
an actuator supported on the rack bar for translation therewith, the actuator including a protrusion projecting therefrom, the actuator positioned to translate between a proximal position and a distal position, wherein the protrusion of the actuator engages the counting mechanism to rotate the counting mechanism, in a first direction, to adjust the indicia of the counting mechanism, visible through the handle assembly, wherein in the proximal position, the protrusion of the actuator is disposed proximal of the counting mechanism, and, in the distal position, the protrusion of the actuator is disposed distal of the counting mechanism.

Abstract
A counter assembly is supported in a handle assembly of a clip applier. The counter assembly includes a counting mechanism, a ratchet mechanism, and an actuator. The counting mechanism is positioned to rotate within the handle assembly and includes indicia visible through the handle assembly. The ratchet mechanism is rotationally coupled to the counting mechanism and prohibits multidirectional rotation of the counting mechanism. The actuator includes a protrusion projecting therefrom. The actuator is positioned to translate between a proximal position and a distal position, wherein the protrusion of the actuator engages the counting mechanism to rotate the counting mechanism, in a first direction, to adjust the indicia of the counting mechanism, which is visible through the handle assembly. In the proximal position, the protrusion of the actuator is disposed proximal of the counting mechanism. In the distal position, the protrusion of the actuator is disposed distal of the counting mechanism.

14. A surgical clip applier, comprising:
-
a handle assembly; a rack bar translatably supported in the handle assembly; a counter assembly supported in the handle assembly and including; a housing defining an aperture having a non-circular profile; a counting mechanism positioned to rotate within the handle assembly including indicia, the counting mechanism visible through the handle assembly; a ratchet mechanism rotationally coupled to the counting mechanism, the ratchet mechanism including a shaft having a pair of radially projecting protrusions, the aperture of the housing configured to receive the shaft including the pair of protrusions, wherein the positioning of the shaft within the non-circular aperture of the housing inhibits multidirectional rotation of the counting mechanism; and an actuator supported on the rack bar for translation therewith, the actuator including a protrusion projecting therefrom, the actuator positioned to translate between a proximal position and a distal position, wherein the protrusion of the actuator engages the counting mechanism to rotate the counting mechanism, in a first direction, to adjust the indicia of the counting mechanism, visible through the handle assembly, wherein in the proximal position, the protrusion of the actuator is disposed proximal of the counting mechanism, and, in the distal position, the protrusion of the actuator is disposed distal of the counting mechanism. - View Dependent Claims (15, 16, 17, 18, 19, 20)
