Abstract

In various embodiments, a shaftless end effector is disclosed. The end effector can comprise an anvil assembly including a staple forming surface. The end effector can also comprise a staple cartridge channel configured to receive a staple cartridge therein. The end effector can include a closure system configured to close the anvil. In various instances, the closure system can also form the staples contained within the staple cartridge. The end effector can also include a cutting member configured to cut tissue positioned intermediate the anvil and the staple cartridge. In various instances, the cutting member can be actuated by the closure system. In other instances, the end effector can include an independent system for actuating the cutting member. In various instances, the end effector can be delivered to a surgical site through a trocar and then operated by one or more actuators that are assembled to the end effector.

Claims

1. An end effector, comprising:

an anvil assembly, comprising;

an anvil frame comprising a staple cartridge channel configured to receive a staple cartridge therein; and

an anvil, comprising;

a proximal pivot end rotatably coupled to said anvil frame;

a movable distal end; and

a staple forming surface;

a closure system configured to simultaneously engage said movable distal end of said anvil and said proximal pivot end of said anvil; and

a drive system including an input connector, wherein said drive system is configured to operate said closure system and transition said anvil from an open position to a closed position, and wherein an actuator can be coupled to said drive system after said end effector is inserted to a treatment location.

2. The end effector of claim 1, wherein said closure system comprises a proximal end slide configured to slideably interface with a proximal end of said anvil frame and engage said proximal pivot end of said anvil to transition said anvil from said open position to said closed position.

3. The end effector of claim 2, wherein said closure system further comprises a distal end slide configured to slideably interface with a distal end of said anvil frame and engage said movable distal end of said anvil to transition said anvil from said open position to said closed position.

4. The end effector of claim 3, further comprising:

a proximal shaft slideably coupled to said proximal end of said anvil frame, wherein said proximal end slide is coupled to said proximal shaft; and

a distal shaft slideably coupled to said distal end of said anvil frame, wherein said distal end slide is coupled to said distal shaft, and wherein said closure system is configured to slide said proximal end slide and said distal end slide toward each other to transition said anvil from said open position to said closed position.

5. The end effector of claim 4, wherein said proximal end slide and said distal end slide are configured to interface with a grasper, and wherein said actuator comprises a grasper.

7. The end effector of claim 1, further comprising a cutting instrument, wherein said cutting instrument is configured to cut a tissue section located between said anvil and said staple cartridge channel when said anvil is transitioned into said closed position.

8. The end effector of claim 1, further comprising:

a rotatable shaft located within said anvil frame; and

a cutting instrument operably engaged with said rotatable shaft, wherein the rotation of said rotatable shaft is configured to move said cutting instrument between said proximal pivot end and said movable distal end of said anvil.

9. The end effector of claim 8, wherein said cutting instrument comprises an I-beam, and wherein said I-beam is configured to deploy a plurality of staples stored in said staple cartridge when said I-beam is advanced distally within said anvil frame.

10. The end effector of claim 1, further comprising a plurality of notches corresponding to a plurality of heights of said anvil, wherein said plurality of notches are configured to provide an indication of a current height of said anvil with respect to said anvil frame.

11. The end effector of claim 1, wherein said closure system comprises a rotatable collar rotatably coupled to a proximal end of said anvil assembly, and wherein said rotatable collar is configured to threadably engage said anvil assembly in order to move said anvil assembly into said closed position.

6. An end effector, comprising:

an anvil assembly, comprising;

an anvil frame comprising a staple cartridge channel configured to receive a staple cartridge therein; and

an anvil, comprising;

a pivot end rotatably coupled to said anvil frame;

a movable second end; and

a staple forming surface;

a closure system configured to engage said second end of said anvil;

a drive system including an input connector, wherein said drive system is configured to operate said closure system and transition said anvil from an open position to a closed position, wherein an actuator can be coupled to said drive system after said end effector is inserted into a treatment location, wherein said closure system comprises a proximal end slide configured to slideably interface with a proximal end of said anvil frame to transition said anvil from said open position to said closed position, and wherein said closure system further comprises a distal end slide configured to slideably interface with a distal end of said anvil frame to transition said anvil from said open position to said closed position; and

a rotatable shaft coupled to said proximal end slide and said distal end slide, wherein rotation of said rotatable shaft in a first direction moves said proximal end slide and said distal end slide towards a center of said anvil frame, and wherein rotation of said rotatable shaft in an opposite direction moves said proximal end slide and said distal end slide away from said center of said anvil frame.

12. An end effector, comprising:

an anvil assembly, comprising;

an anvil frame comprising a staple cartridge channel configured to receive a staple cartridge therein; and

an anvil, comprising;

a proximal pivot end rotatably coupled to said anvil frame;

a movable distal end; and

a staple forming surface;

a closure system configured to engage said movable distal end of said anvil and said proximal pivot end of said anvil; and

a drive system including an input connector, wherein said drive system is configured to operate said closure system and transition said anvil from an open position to a closed position, and wherein an actuator can be coupled to said drive system after said end effector is inserted to a treatment location.
