1. An FTRD comprising:
- a fixed housing;
a removable cartridge body complementary to the fixed housing when in an attached configuration, the removable cartridge body including a plurality of staple receiving slits in a distal end thereof and including a blade movably mounted therein for motion along a cutting path;
a plurality of first staple drivers slidable within the removable cartridge body, each of the first staple drivers having a staple end adjacent to a corresponding one of the staple receiving slits and a driven end;
an actuator disposed in the fixed housing, the actuator moving th first staple drivers into the corresponding staple receiving slits to push staples received therein against an anvil portion of the FTRD when in the attached configuration and for moving the blade along the cutting path when a stapling operation has been completed; and
a plurality of second staple drivers movably disposed in the fixed housing, each of the second staple drivers having a cam end and a driving end connecting to the driven end of a corresponding one of the first staple drivers when in the attached configuration.

Abstract
The FTRD described comprises a removable cartridge body that contains a new load of staples and a new blade for use in the FTRD. The cartridge body can be removed and replaced with a new one once the staples have been used. Rotation of a main shaft by the physician causes the staples to be fired and the blade to be moved along a pre determined path to cut the stapled tissue. Tactile and audible feedback is given to the physician when the stapling phase is complete and the cutting phase is to begin.

14. An FTRD comprising:
-
a fixed housing;
a removable cartridge body complementary to the fixed housing when in an attached configuration, the removable cartridge body containing a plurality of staple receiving slits and a tissue cutting blade;
a plurality of first staple drivers slidable within the removable cartridge body, each of the first staple drivers having a staple end adjacent to a corresponding one of the staple receiving slits and a driven end;
a rotating actuator disposed in the fixed housing, the actuator moving the first staple drivers into the staple receiving slits to drive staples received therein against an anvil portion of the FTRD when in the attached configuration; and
a cam surface adjacent the rotating actuator and a plunger extending from an axis of the rotating actuator, the plunger moving radially relative to the axis between a staple driving position and a tissue cutting position in response to angular movement of the plunger along the cam surface. - View Dependent Claims (15, 16)

17. A removable staple cartridge for an FTRD comprising:
-
a cartridge body complementary to and removably attachable to housing of the FTRD, the cartridge body defining staple containing cavities therein; and
a plurality of first staple drivers slidably retained in the cartridge body, each of the first staple drivers having a staple end which, when the first staple driver is moved from a storage position to a staple firing position, extends into a corresponding one of the staple containing cavities to propel a corresponding one of the staples received therein out of the cartridge body; and
a plurality of second staple drivers movably disposed in the fixe housing, each of the second staple drivers having a cam end and a driving end connecting to the driven end of a corresponding one of the first staple drivers, wherein, when the cartridge body is attached to the housing, driven ends of the second staple drivers are positioned to be sequentially engaged by a drive cam disposed in the housing to successively drive the second staple drivers against corresponding ones of the first staple drive to drive the first staple drivers from the storage to the staple firing position.
