Abstract

A flexible endoscope for extending between an incision and a surgical site, the flexible endoscope including an endoscopic cylinder received by an outer flexible sleeve, the endoscopic cylinder including an outer contact surface received by the flexible sleeve with a helical thread, a flanged structure associated with the flexible sleeve and corresponding to a proximate handle end of said endoscopic cylinder, and a directional guide angularly extending from said outer surface and tapered.

Claims

1. A flexible endoscope for extending between an incision and a surgical site, said flexible endoscope comprising:

an endoscopic cylinder received by an outer flexible sleeve, said endoscopic cylinder having a outer contact surface coaxially received by the flexible sleeve, said flexible sleeve having a helical thread circumscribing substantially along an outer surface of said flexible sleeve,

a flanged structure associated with said flexible sleeve and corresponding to a proximate handle end of said endoscopic cylinder, and

a directional guide angularly and distally extending from said outer surface and being radially tapered from said endoscopic cylinder.

2. The endoscope according to claim 1, further comprising an internal proximal stabilizing support dimensioned to slidably receive a surgical instrument passing through said endoscope while restricting fluid flow at the juncture of said proximal stabilizing support and said surgical instrument, whereby the surgical instrument can be manipulated to a surgical site.

3. The endoscope according to claim 2, wherein said proximal stabilizing support is located between the endoscopic cylinder and a handle of said endoscope.

4. The device according to claim 1 wherein said outer contact surface of said endoscopic cylinder and an inner surface of the flexible sleeve presents a hermetic seal at a juncture thereof.

5. The endoscope according to claim 1 wherein said endoscopic cylinder further comprises a side opening associated with said proximate handle end spaced from a distal endoscopic end, said side opening in fluid communication with said distal endoscopic end.

6. The endoscope according to claim 5, further comprising a lateral support dimensioned to slidably receive a surgical instrument while restricting fluid flow at the juncture of said lateral support and said surgical instrument, whereby said lateral support is located between said side opening and said distal endoscopic end and a proximal stabilizing support is located between said proximate handle end and said side opening.

7. The device according to claim 1, wherein said directional guide is configured to bias a surgical instrument towards said surgical site.
