Abstract

A surgical stapling instrument comprising a stapling assembly, a shaft, a firing member, a closure member, a manually-actuatable closure trigger, and a motor is disclosed. The stapling assembly comprises a first jaw and a second jaw. The first jaw is movably coupled to the second jaw. The shaft is configured to support the stapling assembly. The firing member is configured to transmit a firing motion to the stapling assembly. The firing member comprises a cutting member, a first camming member configured to engage the first jaw, and a second camming member configured to engage the second jaw. The closure member is configured to transmit a push-to-close motion to the stapling assembly. The manually-actuatable closure trigger is operable to impart the push-to-close motion to the closure member. The motor is operably coupled to the firing member to impart the firing motion to the firing member.

Claims

1. A surgical stapling instrument, comprising:

a stapling assembly comprising a first jaw and a second jaw, wherein said first jaw is movably coupled to said second jaw;

a shaft configured to support said stapling assembly;

a firing member configured to transmit a firing motion to said stapling assembly, wherein said firing member comprises;

a cutting member;

a first camming member configured to engage said first jaw; and

a second camming member configured to engage said second jaw;

a closure member configured to transmit a push-to-close motion to said stapling assembly;

a manually-actuatable closure trigger which is operable to impart said push-to-close motion to said closure member; and

a motor, wherein said motor is operably coupled to said firing member to impart said firing motion to said firing member.

2. The surgical stapling instrument of claim 1, wherein said manually-actuatable closure trigger is mechanically coupled to said first jaw of said stapling assembly such that a closure load can be transmitted between said first jaw and said manually-actuatable closure trigger.

3. The surgical stapling instrument of claim 2, wherein the closure load felt at said manually-actuatable closure trigger is directly related to a clamping load experienced at said first jaw.

4. The surgical stapling instrument of claim 1, wherein said first jaw comprises an anvil.

5. The surgical stapling instrument of claim 1, wherein said second jaw comprises a receiving portion configured to receive a staple cartridge.

6. The surgical stapling instrument of claim 5, further comprising said staple cartridge.

7. The surgical stapling instrument of claim 1, further comprising:

a firing trigger; and

a battery, wherein the operation of said firing trigger is configured to operably couple said motor to said battery.

8. The surgical stapling instrument of claim 1, wherein said first camming member is positioned on a first side of said cutting member and said second camming member is positioned on a second side of said cutting member.

9. A surgical stapling instrument, comprising:

a stapling assembly comprising a first jaw and a second jaw, wherein said first jaw is movably coupled to said second jaw;

a shaft configured to support said stapling assembly;

a closure member configured to transmit a cam-to-close motion to said first jaw;

a firing system configured to transmit a firing motion to said stapling assembly, wherein said firing system comprises;

a cutting member; and

camming means for positioning said first jaw relative to said second jaw after said closure member has applied said cam-to-close motion to said first jaw;

a closure trigger which is operable to impart said cam-to-close motion to said closure member; and

a motor, wherein said motor is operably coupled to said firing system to impart said firing motion to said firing system.

10. The surgical stapling instrument of claim 9, wherein said closure trigger is mechanically coupled to said first jaw of said stapling assembly such that a closure load can be transmitted between said first jaw and said closure trigger.

11. The surgical stapling instrument of claim 10, wherein the closure load felt at said closure trigger is directly related to a clamping load experienced at said first jaw.

12. The surgical stapling instrument of claim 9, wherein said first jaw comprises an anvil.

13. The surgical stapling instrument of claim 9, wherein said second jaw comprises a receiving portion configured to receive a staple cartridge.

14. The surgical stapling instrument of claim 13, further comprising said staple cartridge.

15. The surgical stapling instrument of claim 9, further comprising:

a firing trigger; and

a battery, wherein the operation of said firing trigger is configured to operably couple said motor to said battery.

16. The surgical stapling instrument of claim 9, wherein said cutting member is arranged within said camming means.
