Abstract

A surgical apparatus for guiding the movement of a surgical tool in relation to the surrounding anatomy of a patient includes a surgical tool having an articulation member. The apparatus also has an image capturing device, a monitor, a control member, and at least one marker on the surgical tool for determining an orientation and attitude of the surgical tool in relation to the visual image on the monitor. The image capturing device takes visual images of the articulating member. The monitor displays the visual images taken by the image capturing device. The control member operates and guides movement of the articulating member. The marker can be colors, symbols, letters, number, or in any combination thereof. An endoscope and a display may also be included.

First claim

What is claimed:

1. A surgical apparatus for guiding movement of a surgical tool in relation to a surrounding anatomy of a patient, the surgical apparatus comprising:
a surgical tool having an articulating member;
an image capturing device configured to take a visual image of the articulating member;
a monitor configured to display the visual image taken by the image capturing device;
a control member in communication with the articulating member such that articulation of the control member operates and guides articulation of the articulating member;
at least one first marker on the surgical tool for determining an orientation and attitude of the surgical tool in relation to the visual image on the monitor, the at least one first marker having a first indicium indicating a spatial direction; and
at least one second marker placed about the control member, the at least one second marker having a second indicium corresponding to the first indicium, such that the at least one second marker provides an indication of an operation of the control member to guide the surgical tool in the spatial direction corresponding to the at least one first marker,
wherein the orientation and attitude of the articulating member are defined by the first and second indicia and articulation of the articulating member is controlled by the control member acting on the articulating member independent of the visual image displayed on the monitor.

2. The surgical apparatus according to claim 1 , wherein the at least one first marker is placed about a circumference of a distal region of the surgical tool.

3. The surgical apparatus according to claim 2 , wherein the control member includes at least one knob, the at least one second marker placed about the at least one knob.

4. The surgical apparatus according to claim 3 , wherein the respective first and second indicia of the at least one first and second markers are selected from the group consisting of colors, symbols, letters, numbers, and a combination thereof.

5. The surgical apparatus according to claim 1 , wherein the image capturing device is an endoscope.

6. The surgical apparatus according to claim 1 , wherein the control member is at a location remote from the surgical tool.

7. The surgical apparatus of claim 1 , wherein the control member is configured to move the articulating member in the respective spatial direction indicated by the at least one first marker.

8. The surgical apparatus according to claim 1 , wherein the surgical tool further includes a mechanical linkage system interconnected between the control member and the articulating member such that the control member articulates the articulating member via the mechanical linkage system.

9. The surgical apparatus according to claim 1 , wherein the surgical tool further includes at least one motor, the at least one motor interconnected between the control member and the articulating member such that the control member articulates the articulating member via the at least one motor.

10. A surgical apparatus comprising:
a surgical tool having an articulating member, and a control member configured to control articulation of the articulating member, the control member in communication with the articulating member;
a first plurality of markers located about a distal region of the surgical tool, each marker of the first plurality of markers having a first indicium corresponding to one direction of a plurality of directions; and
a second plurality of markers located about the control member, wherein each marker of the second plurality of markers has a second indicium corresponding to the first indicium such that movement of the control member toward one marker of the second plurality of markers moves the articulating member in the direction of the corresponding marker of the first plurality of markers,
wherein the orientation and attitude of the articulating member are determined by the first and second indicia and articulation of the articulating member is controlled by the control member acting on the articulating member independent of a visual image of the articulating member.

11. The surgical apparatus of claim 10 , further comprising:
an endoscope; and
a display.

12. The surgical apparatus according to claim 10 , wherein the control member is at a remote location that is different from the surgical tool.

13. The surgical apparatus according to claim 10 , wherein the control member having at least one knob.

14. The surgical apparatus according to claim 13 , wherein located about the at least one knob is the second plurality of markers being color coded to correspond to the first plurality of markers being color strips placed about a distal region of the articulating member.

15. The surgical apparatus of claim 10 , wherein the respective first and second indicia of the first and second pluralities of markers are selected from the group consisting of colors, symbols, letters, numbers, and a combination thereof.
