Abstract
An elongated medical clip applying device having a handle grip assembly on a proximal end thereof and an elongated channel with a pair of squeezable jaws on a distal end thereof. A push rod arrangement is included having a distal end and a proximal end. The push rod arrangement is utilized for advancing a plurality of clips in a sequential manner between the jaws. The push rod includes a multiplier extender arrangement to increase the distance of travel of the distal end of the push rod arrangement a multiple of the distance of travel of the proximal or input end of the push rod arrangement.

11. A method of extending the distance of travel of the distal end of a pushed movable component on a distal end of a frame of a medical device relative to the distance of travel of an input component on a proximal end of said frame, comprising:
-
connecting a multiplier extender arrangement between said pushed movable component and said input component on said frame of said medical device; arranging a plurality of connected articulated links in said multiplier extender arrangement; pushing said plurality of connected articulated links in a distal direction a first distance by said input component as said links are in a zig-zag orientation; pushing said pushed movable component a second distance, which second distance is greater than said first distance; and straightening out said zig-zag orientation of said links as they are moved distally in said extender arrangement. - View Dependent Claims (12, 13, 14)

15. A method of extending the reachable output length of a medical device where the input length of said device is limited, comprising:
-
connecting a multiplier arrangement between a first elongated input rod and an input component on a frame of said medical device; arranging a plurality of connected articulated links in said multiplier arrangement; moving said first elongated input rod longitudinally a first distance along a longitudinal axis thereof from said input component and into said multiplier arrangement as said links are in a zig-zag orientation; moving an output rod longitudinally a second distance along a longitudinal axis thereof from said multiplier arrangement to push a movable medical tool of said medical device; and straightening out said zig-zag orientation of said links as they are moved distally in said multiplier arrangement.
