System and method for endoscopic imaging and endosurgery
First Claim
1. An endoscopic surgical instrument for use in endoscopic surgery comprising:
- an elongated insertion shaft including a distal end-effector and an opposite proximal end;
an insertion tube configured to receive the elongated insertion shaft therethrough;
a handle portion operably coupled to the proximal end and configured to manually manipulate the end-effector during endoscopic surgery;
a video endoscope component coupled to the shaft having a distal viewing face positioned rearward of the distal end effector to view the distal end-effector from a position along said shaft; and
a video display device operably coupled to the endoscope component and coupled to said insertion tube proximate and adjacent to the proximal end of said shaft at a viewing angle and location therealong such that an image of the end-effector displayed on said display device appears to be a substantially direct view of said end-effector that is positioned in-line with the insertion shaft.

Abstract
A video image display is attached to a video endoscopic surgical component such as video endoscope, an endoscopic surgical instrument, a carrier for coupling the endoscope and the instrument, or a cannula through which the endoscope or the instrument is passed into a body part. Attachment is by means of an attachment mechanism which may be adjusted to enable the display position to be varied with respect to the component to which it is attached. According to another embodiment, a carrier in the form of an elongated tube is employed to combine and relate the movement of the endoscope and endosurgical instrument, which, by means of the carrier, may be jointly inserted into a body part either directly or through a cannula, enabling the surgeon to operate both the endoscope and the instrument with a single hand. A video display attached to the endoscope or carrier and positioned near the instrument actuation handle provides the surgeon with a visual perspective similar to that encountered in open surgery.

16. A video endoscope system for use by a surgeon in endoscopic surgery:
-
an insertion tube arranged to receive a surgical instrument having an elongated shaft and an end-effector; an elongated endoscope component received within the insertion tube, the endoscope component being arranged to facilitate viewing of the end-effector of the received surgical instrument; a video display for displaying an image of the end-effector viewed by the endoscope component coupled proximate a proximal end of said insertion tube; and a handle operably coupled to the surgical instrument for actuation of the end effector, and to the insertion tube for positioning of end-effector and said endoscope component as a unit, independent of the operation of the end-effector and in a manner substantially maintaining said end-effector in the field of view of said endoscope component during operation and manipulation of the handle such that a surgeon operating the endoscope system by the handle will view and perceive the image of the end-effector on the video display as being directly viewed at a true position of the end-effector from the perspective of the surgeon, enabling the surgeon to effectively perform remote surgery with the hand-eye coordination approximating that of open surgery. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28)

29. An endoscopic surgical instrument for use in endoscopic surgery comprising:
-
an elongated insertion shaft including a distal end-effector and an opposite proximal end; a handle portion operably coupled to the proximal end and configured to manually manipulate the end-effector during endoscopic surgery; a video endoscope component coupled to the shaft having a distal viewing face positioned rearward of the distal end effector to view the distal end-effector from a position along said shaft; a video display device operably coupled to the endoscope component and mounted proximate and adjacent to the proximal end of said shaft at a viewing angle and location therealong such that an image of the end-effector displayed on said display device appears to be a substantially direct view of said end-effector that is positioned in-line with the insertion shaft; an elongated insertion tube configured to receive the elongated insertion shaft therethrough; a cannula device arranged to receive the insertion tube therethrough; and a rotation preventing mechanism adapted to substantially prevent rotation of the insertion tube within the cannula while allowing axial translation of the insertion tube relative to the cannula. - View Dependent Claims (30, 31)

32. A method of performing endoscopic surgery comprising the steps of:
-
inserting into a body part through a natural orifice or incision an insertion tube; positioning through said tube a surgical instrument having an elongated shaft and an end effector; viewing an image of the end effector from an endoscope component received within the insertion tube and arranged to facilitate viewing of the end-effector of the received surgical instrument; displaying the image of the end effector on a video display coupled proximate a proximal end of said insertion tube; and operating a handle operably coupled to the surgical instrument for actuation of the end effector, and to the insertion tube for positioning of said end-effector and said endoscope component as a unit, independent of operation of the end-effector and in a manner substantially maintaining said end-effector in the field of view of said endoscope component during operation and manipulation of the handle such that a surgeon operating the endoscope system by the handle will view and perceive the image of the end-effector on the video display as being directly viewed at a true position of the end-effector from the perspective of the surgeon, enabling the surgeon to effectively perform remote surgery with the hand-eye coordination approximating that of open surgery. - View Dependent Claims (33, 34, 35)
