Abstract

Apparatus for use in an operating theater equipped with a surgical table, comprises a lifting frame attachable to the surgical table and adapted for lifting a body part of a subject undergoing a surgical procedure upon the surgical table, and comprising an upright support post incorporating a jack, and a lifting arm pivotally mounted upon the post, whereby the arm can be turned about the upright support post on thrust bearing to either overhang the surgical table, or be pivoted away to permit access to the surgical table. The arm is adapted to support a retractor that comprises a blade portion incorporating a plurality of independent lighting devices positioned in light ports and configured to provide discrete illumination selectively to zones within the surgical field according to (a) a predetermined sequence program, or (b) a sequence determined by a user of the retractor.

Claims (41)

1. A method comprising:

applying a lifting force to a retractor inserted into an incision that is formed superior to a sternal notch of a patient, the retractor extending under a manubrium of the patient, the lifting has been changed to force opening the incision, the retractor having a blade portion, a neck portion upstanding from the blade portion, and a curved heel portion formed between the blade portion and the neck portion;

selectively illuminating, via a first light port disposed on an outer surface of the curved heel portion of the retractor, fatty remnants of a thymus gland for mobilization or dissection to improve access to a pericardium;

selectively illuminating, via a second light port disposed on an underside of the blade portion of the retractor, at least one of the pericardium, a heart, an aorta, and a pulmonary artery, such that the first light port and the second light port are independently operable; and

exposing the aorta.

2. The method of claim 1 , comprising establishing a cardiopulmonary bypass.

3. The method of claim 2 , comprising:

clamping the aorta;

arresting the heart;

opening the aorta; and

illuminating an interior of the aorta and an aortic valve.

4. The method of claim 3 , comprising viewing, via a camera, a magnified view of the interior of the aorta and the aortic valve.

5. The method of claim 4 , wherein the viewing comprises utilizing a screen disposed above the incision.

6. The method of claim 4 , comprising adjusting the magnified view by adjusting at least one of an axial position, a roll position, a yaw position, and a pitch position of the camera.

7. The method of claim 1 , comprising replacing an aortic valve.

8. The method of claim 1 , comprising:

illuminating an interior of the aorta and an aortic valve comprises utilizing light emitted from a third light port of the retractor.

9. The method of claim 1 , comprising turning off the first light port thereby reducing reflected light near an entrance to the incision.

10. The method of claim 1 , wherein the applying the lifting force comprises utilizing a winch that is operatively coupled to the retractor.

11. The method of claim 1 , comprising opening the pericardium to expose at least one of the heart, the aorta, and the pulmonary artery.

12. A method comprising:

responsive to a lifting force, a retractor opening an incision formed superior to a sternal notch of a patient, the retractor having a blade portion, a neck portion upstanding from the blade portion, and a curved heel portion formed between the blade portion and the neck portion;

selectively illuminating, via a first light port disposed on an outer surface of the curved heel portion of the retractor, fatty remnants of a thymus gland for mobilization or dissection to improve access to a pericardium; and

selectively illuminating, via a second light port disposed on an underside of the blade portion of the retractor, at least one of the pericardium, a heart, an aorta, and a pulmonary artery such that the first light port and the second light port are independently operable.

13. The method of claim 12 , comprising:

facilitating opening of the aorta; and

illuminating, via the retractor, an interior of the aorta and an aortic valve.

14. The method of claim 13 , comprising providing, via a camera, a magnified view of at least one of the interior of the aorta and the aortic valve.

15. The method of claim 14 , wherein adjustments made to at least one of an axial position, a roll position, a yaw position, and a pitch position of the camera adjust the magnified view.

16. The method of claim 14 , wherein the camera is disposed on the retractor.

17. The method of claim 12 , comprising facilitating replacement of an aortic valve.

18. The method of claim 12 , wherein the lifting force is applied via a winch operatively coupled to the retractor.

19. A method comprising:

responsive to a lifting force, a retractor opening an incision formed superior to a sternal notch of a patient, the retractor having a blade portion, a neck portion upstanding from the blade portion, and a curved heel portion formed between the blade portion and the neck portion;

selectively illuminating, via a first light port disposed on an outer curved surface of the heel portion of the retractor, an entrance to the incision;

selectively illuminating, via a second light port disposed on an underside of the blade portion of the retractor, at least one of a pericardium, a heart, an aorta, and a pulmonary artery;

selectively illuminating, via a third light port disposed on the retractor, an interior of the aorta and an aortic valve; and

facilitating replacement of the aortic valve.

20. The method of claim 19 , comprising providing, via a camera, a magnified view of at least one of the interior of the aorta and the aortic valve.

21. The method of claim 20 , wherein adjustments made to at least one of an axial position, a roll position, a yaw position, and a pitch position of the camera adjust the magnified view.

22. The method of claim 19 , wherein the lifting force is applied via a winch operatively coupled to the retractor.
