Continuous use self-propelled stapling instrument
A surgical instrument for treating the tissue of a patient is disclosed. The surgical instrument comprises a housing including a handle, a housing frame comprising a housing connector, and a drive system comprising at least one electric motor. The surgical instrument further comprises a shaft assembly releasably assembled to the housing including a shaft frame comprising a proximal connector and a distal connector, wherein the proximal connector is releasably coupled to the housing connector and a shaft drive system comprising at least one rotatable shaft operably coupled to the electric motor. The surgical instrument further comprises an end effector releasably assembled to the shaft assembly including an end effector frame comprising an end effector connector releasably coupled to the distal connector of the shaft assembly, a plurality of staple cartridges removably stored in the end effector, and a plurality of end effector drivers operably coupled to the rotatable shaft.
1. A method for stapling tissue of a patient with a surgical stapling assembly comprising an end effector assembly and a projector, wherein the method comprises:
projecting, by the projector, an image onto the tissue, wherein the image comprises information specific to a staple-firing stroke including a primary firing path and an alternative firing path; and
stapling the tissue, by the surgical stapling assembly, according to the projected image.
2. The method of claim 1 , further comprising tracking, by the projector, movement of the end effector assembly.
3. The method of claim 1 , wherein the projected image comprises a first image, wherein the method further comprises projecting, by the projector, a second image onto the tissue, and wherein the first image and the second image are different.
4. The method of claim 1 , wherein the projected image is three dimensional.
5. The method of claim 1 , further comprising projecting, by the projector, an updated image onto the tissue after stapling the tissue.
6. A method for stapling tissue of a patient with a surgical stapling assembly comprising a handle, an end effector assembly and a projector, wherein the method comprises:
positioning the surgical stapling assembly to direct a projector lens of the projector toward the tissue;
projecting, by the projector, an image onto the tissue, wherein the image comprises information specific to a staple-firing stroke;
repositioning the surgical stapling assembly according to the projected image;
stapling the tissue, by the surgical stapling assembly, according to the projected image; and
modifying, by a controller, the projected image during the stapling of the tissue by the surgical stapling assembly to continuously update the projected image.
7. The method of claim 6 , further comprising tracking, by the projector, movement of the end effector assembly.
8. The method of claim 6 , wherein the projected image comprises a first image, wherein the method further comprises projecting, by the projector, a second image onto the tissue, and wherein the first image and the second image are different.
9. The method of claim 6 , wherein the projected image is three dimensional.
10. The method of claim 6 , wherein the projected image comprises a primary firing path and an alternative firing path.
11. The method of claim 6 , further comprising projecting, by the projector, an updated image onto the tissue after stapling the tissue.
12. A method for stapling tissue of a patient with a surgical stapling assembly comprising a handle, an end effector assembly and a projector, wherein the method comprises:
positioning the surgical stapling assembly to direct a projector lens of the projector toward the tissue;
projecting, by the projector, an image onto the tissue prior to clamping the tissue of the patient, wherein the image comprises information specific to a staple-firing stroke;
clamping, after projecting the image, the tissue of the patient with the surgical stapling assembly;
stapling the tissue with the surgical stapling assembly;
modifying, by a controller, the projected image during the stapling of the tissue to continuously update the projected image.
13. The method of claim 12 , further comprising tracking, by the surgical stapling assembly, movement of the end effector assembly.
14. The method of claim 12 , wherein the projected image comprises a first image, wherein the method further comprises projecting, by the projector, a second image onto the tissue, and wherein the first image and the second image are different.
15. The method of claim 12 , wherein the projected image is three dimensional.
16. The method of claim 12 , wherein the projected image comprises a primary firing path and an alternative firing path.
