INTERCHANGEABLE TOOLS FOR SURGICAL INSTRUMENTS
First Claim
1. A surgical tool for use with a surgical instrument having a handle assembly that operably supports a drive system therein for generating drive motions upon actuation of a movable handle portion thereof and an elongated body operably supporting a control rod therein for transferring the drive motions, said surgical tool comprising:
- a housing removably couplable to said elongated body;
a drive assembly operably supported in said housing and removably couplable to said control rod; and
a pair of non-staple forming jaws operably coupled to said drive assembly such that upon application of a said drive motion to said drive assembly in a first direction causes said pair of non-staple forming jaws to each simultaneously move in a closing direction toward each other and upon application of another said drive motion in a second direction, said non-staple forming jaws each simultaneously move in an opening direction away from each other.

Abstract
A surgical tool system. Various embodiments of the surgical tool system may comprise surgical instrument that has a handle assembly that operably supports a drive system therein for generating drive motions upon actuation of a movable handle portion operably coupled to the handle assembly. An elongated body protrudes from the handle assembly and operably supports a control rod therein that interfaces with the drive system. The surgical tool system further includes at least two surgical tools selected from the group of surgical tools consisting of: manipulators, nippers, scissors, endocutters, tissue thickness measurement devices, staple appliers, clip appliers, syringes for applying glue, sealant, drugs or medicaments and cauterization devices wherein each of the surgical tool within the group of surgical tools at least has a housing that is removably couplable to the elongated body and a drive assembly that is removably couplable to the control rod for receiving the drive motions therefrom.

11. A surgical tool for use with a surgical instrument having a handle assembly that operably supports a drive system therein for generating drive motions upon actuation of a movable handle portion thereof and an elongated body operably supporting a control rod therein for transferring the drive motions, said surgical tool comprising:
-
a housing directly couplable to said elongated body; a drive assembly operably supported in said housing and carrier and removably couplable to said control rod; a staple-forming anvil non-movably supported by said housing; and a plurality of staples supported in a distal end of said housing and oriented to be sequentially driven into said staple-forming anvil upon application of a said drive motion to said drive assembly. - View Dependent Claims (12)

13. A surgical tool for use with a surgical instrument having a handle assembly that operably supports a drive system therein for generating drive motions upon actuation of a movable handle portion thereof and an elongated body operably supporting a control rod therein for transferring the drive motions, said surgical tool comprising:
-
a housing directly couplable to said elongated body; a shaft extending from said housing and having a plurality of surgical clips therein; a pair of opposed, moveable jaws attached to and extending from said shaft, said jaws for receiving each of said surgical clips serially therein when said jaws are in an open position, and for forming each of said surgical clips received serially therein when said jaws are moved to a closed position; a moveable forming mechanism removably couplable to the control rod when said housing is coupled to the elongated body, said forming mechanism moving said jaws from the open position to the closed position upon application of a first drive motion from the control rod so as to form each of said surgical clips received serially therein, and from the closed position to the open position upon application of a second drive motion to said forming mechanism by the control rod; and a feeding mechanism operatively interacting with said movable forming mechanism, said feeding mechanism having a feed plate movable in response to movement of said forming mechanism and being releasably coupled to a clip pusher of said feed mechanism, wherein said clip pusher is stationary and uncoupled from said feed plate upon application of said first drive motion to said forming mechanism, and said clip pusher is moveable and operatively coupled to said feed plate upon application of said second drive motion to said movable forming mechanism so as to move each of said surgical clips serially from said shaft into said jaws. - View Dependent Claims (14)
