Abstract

A module for attachment to a medical instrument to scan the anatomy with a beam of radiation. The module comprising a housing suitable for insertion in the anatomy that includes a window and a fastener to attach the housing to a medical instrument, an oscillating reflector within the housing that directs a beam of radiation onto the anatomy, and a collector to receive radiation returned from the anatomy.

Claims

1. A module for attachment to a medical instrument to scan the anatomy with a beam of radiation, the module comprising:

a housing suitable for insertion in the anatomy that includes a window and a fastener to attach the housing to a medical instrument;

an oscillating reflector within the housing that directs a beam of radiation onto the anatomy; and

a collector to receive radiation returned from the anatomy.

2. The module of claim 1 further comprising a cable extending from the housing that links the module to a scanning beam device.

3. The module of claim 1 wherein the medical instrument is an endoscope.

4. The module of claim 1 wherein the medical instrument includes a cutting tool.

5. The module of claim 1 wherein the fastener is a linkage having a distal end and a proximal end, wherein the distal end of the linkage is attached to the module and the proximal end is attached to a medical instrument.

6. The module of claim 5 wherein the medical instrument includes a longitudinal axis and the module extends from the distal end of the medical instrument along the longitudinal axis.

7. The module of claim 6 wherein the module is pivotally attached to the linkage such that the module can be positioned in a plurality of position to scan the anatomy.

8. The module of claim 6 wherein the linkage is pivotally attached to the medical instrument so the module can be moved from a first position along the longitudinal axis of the medical instrument to a second position in which the module is offset from the longitudinal axis of the medical instrument.

9. The module of claim 8 wherein the linkage includes a first linking member and a second linking member each having a first end and a second end, wherein the each of the first linking member and the second linking member are attached at a point at the first end of the linking member to the medical instrument and at a point at the second end of the linking member to the module, further wherein each of the first linking member and the second linking member are pivotalable about the points of attachment to the medical instrument and the module.

10. The module of claim 9 wherein at least one of the first linking member and the second linking member includes an actuator for moving the module from the first position along the longitudinal axis of the medical instrument to the second position in which the module is offset from the longitudinal axis of the medical instrument.

11. The module of claim 10 wherein the actuator is a shape memory actuator.

12. The module of claim 9 wherein at least one of the first linking member and the second linking member includes a spring.

13. The module of claim 5 wherein the medical instrument is an endoscope.

14. The module of claim 1 wherein the medical instrument is a grasper.

15. The module of claim 1 wherein the medical instrument is a surgical stapler.

16. A medical instrument for use with a scanning beam device, the medical instrument comprising:

a shaft that is insertable in the anatomy, the shaft including a first working channel; and

a module within the first working channel of the shaft for scanning the anatomy, the module comprising;

a housing that is suitable for insertion in the anatomy that includes a window;

an oscillating reflector within the housing that directs a beam of radiation onto the anatomy; and

a collector to receive radiation returned from the anatomy;

17. The medical instrument of claim 16 wherein the module further comprises a cable extending from the housing to link the deployable module to a scanning beam device.

18. The medical instrument of claim 16 wherein the medical instrument includes a second working channel and a cutting tool is deployed through the second working channel.

19. The medical instrument of claim 16 wherein the medical instrument is a surgical stapler including a handle portion and an end effector, wherein the shaft connects the handle portion and the end effector and has the module within the shaft near the end effector.

20. A medical instrument for use with a scanning beam device, the medical instrument comprising:

a shaft that is insertable in the anatomy having a distal penetrating tip, wherein at least a portion of the shaft is transparent; and

a module within the shaft to scan the anatomy, the module comprising;

an oscillating reflector that directs a beam of radiation on the anatomy; and

a collector to receive radiation returned from the anatomy;

wherein the reflector and collector are aligned with the transparent portion of the shaft.

21. The medical instrument of claim 20 further comprising a cable extending from the shaft to link the module to a scanning beam device.

22. The medical instrument of claim 20 wherein the medical instrument is a needle.

23. The medical instrument of claim 20 wherein the medical instrument is a trocar.

24. The medical instrument of claim 23 wherein the trocar includes a cannula and a portion of the cannula is transparent such that the reflector and collector are aligned with the portion of the cannula that is transparent.

25. A surgical instrument for use with a scanning beam device, the surgical instrument comprising:

an elongate shaft having a distal end, a proximal end, and a channel therethrough, the elongate shaft including a module for scanning the anatomy, the module comprising;

a resonant reflector that directs a beam of radiation on the anatomy; and

a collector to receive radiation returned from the anatomy;

a plurality of jaw members attached to the distal end of the shaft, the jaw members including grasping or cutting elements positioned in an opposed facing relationship; and

a handle at the proximal end of the shaft operatively configured to open and close the jaw members.

26. The surgical instrument of claim 25 wherein the scanning module is mounted within the distal end of the shaft between the jaw members.

27. A surgical stapler comprising:

a handle portion operably configured to produce a firing motion;

a shaft attached to the handle portion for transferring the firing motion for deploying a staple, the shaft including a module for scanning the anatomy, the module comprising;

a resonant reflector that directs a beam of radiation on the anatomy; and

a collector to receive radiation returned from the anatomy;

an end effector distally attached to the shaft that includes a plurality of surgical staples which are deployed in response to the firing motion; and

a firing mechanism responsive to the firing motion that transfers the firing motion to the end effector.
