Abstract

A surgical instrument for treating tissue during use of a diagnostic scanning device. The surgical instrument includes a housing, an actuating mechanism and an end effector assembly. The actuating mechanism is configured to activate the end effector assembly to treat tissue. At least a portion of the end effector is made of a material that is compatible with the diagnostic scanning device and allows a user to insert and activate the end effector to treat tissue at a surgical site within a patient while the surgical site is monitored during diagnostic scanning device.

First claim

What is claimed is:

1. A surgical instrument for treating tissue during use of a diagnostic scanning device, the surgical instrument comprising:
a housing;
an end effector assembly including first and second jaw members moveable relative to one another and a plurality of fasteners; and
an actuating mechanism configured to eject the plurality of fasteners from the end effector assembly;
wherein at least a portion of the end effector assembly is constructed from a material that is compatible with the diagnostic scanning device and that allows a user to insert and activate the end effector assembly to thereby treat tissue at a surgical site within a patient while the surgical site is monitored during diagnostic testing, wherein the entire end effector assembly is at least one of clear, transparent, translucent, and radio-translucent to the scanning device.

2. The surgical instrument according to claim 1 , wherein the diagnostic scanning device is selected from the group consisting of magnetic resonance imaging, computed axial tomography scan, and x-ray.

3. The surgical instrument according to claim 1 , wherein the compatible material is a non-ferrous metal.

4. The surgical instrument according to claim 1 , wherein the compatible material is a non-metallic material such that at least a portion of the surgical instrument is radio-translucent during diagnostic testing.

5. The surgical instrument according to claim 1 , wherein the actuating mechanism is a handle assembly, the handle assembly being operatively coupled to the end effector assembly, wherein actuation of the handle assembly operates the end effector assembly to treat tissue.

6. The surgical instrument according to claim 1 , wherein the surgical instrument is a surgical stapling device.

7. The surgical instrument according to claim 6 , wherein the end effector assembly includes a stapling cartridge disposed on the first jaw member and an anvil assembly disposed on the second jaw member, each being entirely composed of a material being compatible with the diagnostic scanning device to thereby staple tissue at the surgical site within the patient while the surgical site is monitored during diagnostic testing.

8. The surgical instrument according to claim 7 , wherein the stapling cartridge and the anvil assembly are approximated towards each other to clamp tissue therebetween and to clinch the plurality of fasteners in tissue upon expulsion of the plurality of fasteners at the surgical site within a patient while the surgical site is monitored during diagnostic testing.

9. The surgical instrument according to claim 1 , wherein the surgical instrument is a surgical clip applier.

10. The surgical instrument according to claim 9 , wherein the clip applier further includes a handle portion, and a body extending distally from the handle portion and defining a longitudinal axis, wherein at least a portion of the body and the first and second jaw members are constructed from a material that is compatible with the diagnostic scanning device, wherein the clip applier is configured to apply each fastener of the plurality of fasteners to tissue at the surgical site within a patient while the surgical site is monitored during diagnostic testing.

11. The surgical instrument according to claim 1 , wherein the end effector assembly is transparent to the scanning device.

12. The surgical instrument according to claim 1 , wherein the end effector assembly is radio-translucent to the scanning device.

13. The surgical instrument according to claim 1 , wherein the end effector assembly includes a body portion that supports the first and second jaw members.

14. A method of treating tissue during use of a diagnostic scanning device, the method comprising:
providing a surgical instrument including a housing, an end effector assembly having a plurality of fasteners, and an actuating mechanism configured to activate the end effector assembly, wherein at least a portion of the end effector assembly is constructed from a material that is compatible with the diagnostic scanning device and that allows a user to insert and activate the end effector assembly to thereby treat tissue at a surgical site within a patient while the surgical site is monitored during diagnostic testing, wherein the entire end effector assembly is at least one of clear, transparent, translucent, and radio-translucent to the scanning device;
inserting the end effector assembly into the surgical site;
scanning and monitoring the surgical site with the diagnostic scanning device; and
applying the plurality of fasteners to the tissue with the surgical instrument while scanning and monitoring the surgical site.

15. The method according to claim 14 , wherein the surgical instrument is a surgical stapling instrument.

16. The method according to claim 14 , wherein the surgical instrument is a surgical clip applier.

17. The method according to claim 14 , wherein the end effector assembly includes a stapling cartridge and an anvil assembly, each being entirely composed of a material being compatible with the diagnostic scanning device to thereby staple tissue at the surgical site within a patient while the surgical site is monitored during diagnostic testing.

18. The method according to claim 14 , wherein the diagnostic scanning device is selected from the group consisting of magnetic resonance imaging, computed axial tomography scan and x-ray.

19. The method according to claim 14 , wherein the compatible material is a non-ferrous metal.

20. The method according to claim 14 , wherein the compatible material is a non-metallic material.
