Abstract

Claims (40)

1. In a method for a closed chest, video-assisted diagnostic or surgical treatment of a patient that comprises

positioning a viewing scope having an elongated nosepiece suitable for gathering and transmitting images to a small video camera so that the nosepiece is inserted through a first percutaneous intercostal opening in the patient to view an internal region of the patient requiring diagnostic or surgical treatment and transmitting the image so gathered through the video camera to a viewing monitor,

providing at least a second percutaneous opening suitable for inserting a surgical or diagnostic instrument therethrough,

inserting a first diagnostic or surgical instrument through said second opening to perform an internal diagnostic or surgical procedure in the patient's cavity while viewing the image of said procedure on the monitor, the improvement that comprises

(a) draping said monitor with a transparent, sterile surgical drape, said drape completely covering said monitor and being fastened around a periphery of a screen of said monitor, and

(b) positioning said draped monitor within a surgical field so that the surgeon can perform the internal surgical or diagnostic procedure and view it on said monitor so that the surgeon's visual access to the monitor correlates as closely as possible to the visual access of an input end of the viewing scope.

2. The improvement of claim 1 , wherein the monitor is a flat panel monitor.

3. The improvement of claim 1 , wherein said draped monitor is on a movable cart having a sterilizable adjustable arm that allows the monitor to be positioned within the surgical field and adjusted to enhance the surgeon's visual alignment.

4. The improvement of claim 1 , wherein the closed-chest surgical treatment of the patient is performed on an operating table having a means to hold the viewing monitor within the surgical field and adjust the position of the viewing monitor within the surgical field to enhance the surgeon's visual alignment.

5. The improvement of claim 4 , wherein said means to hold the viewing monitor is a flexible, adjustable arm having a proximal and distal ends, said proximal end connected to the operating table and said distal end having a means for firmly holding said viewing monitor in place.

6. The improvement of claim 1 , wherein the video camera of said viewing scope is positioned at about a 90° angle relative to said elongated nosepiece to enable the surgeon to maximize proximity to the patient in performing the surgical treatment.

7. The improvement of claim 1 , wherein the drape is connected to the viewing monitor, thereby ensuring a high resolution image.

8. The improvement of claim 7 , wherein the drape is connected to the viewing monitor by adhesive.

9. The improvement of claim 8 , wherein the adhesive connects the drape to the monitor adjacent to the screen.

10. The improvement of claim 7 , wherein a portion of the drape covering a screen of the monitor is pulled taut.

11. The improvement of claim 1 wherein a surgical retractor provides percutaneous access for the insertion of the surgical or diagnostic instrument into the patient's internal region, said retractor comprising

(a) two handles suitable for grasping positioned opposite each other and pivotally connected so that the handles move reciprocatingly relative to each other,

(b) a head means connected to each handle so that each head means moves reciprocatingly relative to the other,

(c) a means for locking the heads at a present distance from each other,

(d) each head means having a connector means suitable for connecting a blade, and

(e) a blade connected to each head means through the connector means with each blade having a width, depth and thickness.

12. The improvement of claim 11 wherein the surgical retractor is designed so that each blade has an inside face and an outside face, with the inside face of each blade facing the inside face of the other blade and the outside face of each blade is designed to (i) minimize the trauma to the patient's body at the incision when the head means and blades are spread apart, (ii) stabilize the blades in the incision and (iii) allow customization for each patient's anatomy.

13. A flexible sterile drape for covering a video monitor within a surgical field of a surgical operation to be performed on a patient, which drape comprises a window formed of a transparent material within a perimeter of the drape and positioned to cover a screen of said monitor, and fastening means around the perimeter of the drape for completely covering the video monitor to ensure the monitor's sterility and suitability for retaining within a surgical field during a surgical operation on a patient and for fastening said drape around a periphery of said screen.

14. The sterile drape of claim 13 , wherein the entire drape is transparent.

15. The sterile drape of claim 13 , that is packaged in a sterile package.

16. The sterile drape of claim 13 , wherein the fastening means includes adhesive strips.

17. The sterile drape of claim 13 , that is made of polyethylene or polypropylene.

18. The sterile drape of claim 13 , wherein the fastening means includes hook and loop fasteners.

19. The sterile drape of claim 13 , wherein the fastening means includes snaps.

20. The sterile drape of claim 13 , further comprising a sterile package in combination with instructions for enclosing a viewing monitor.

21. The improvement of claim 13 , wherein a portion of the drape covering a screen of the monitor is pulled taut.

22. A flexible sterile drape for covering a video monitor located within a surgical field of a surgical operation, the drape comprising:

a drape body configured to completely cover a video monitor,

a transparent viewing window of transparent material located within the drape body, and

a fastener configured to connect the drape body to the video monitor around a perimeter of a screen of the video monitor.

23. The flexible drape of claim 22 , wherein said drape body has a cruciform shape.

24. The flexible drape of claim 22 , wherein the fastener is a plurality of segments of hook and loop fastener.

25. The flexible drape of claim 22 , wherein the fastener is adhesive.

26. The flexible drape of claim 22 , used in combination with the video monitor.

27. The flexible drape of claim 22 , wherein the drape is packaged in a sterile package combined with instructions for enclosing a viewing monitor.
