Abstract

An apparatus (100) for cutting tissue. The apparatus includes a shaft (101), a flat portion (102), and a blade (104). The shaft has a first end and a second end opposite the first end. The first end forms a handle for the apparatus. The flat portion is formed adjacent the second end of the shaft and angled relative to the shaft. The flat portion has a generally triangular indentation (109). The blade cuts the tissue. The blade is secured within the triangular indentation of the flat portion. The blade has a V-shaped cutout formed by inner sharpened portions for engaging the tissue.

Claims

-9-AMENDED CLAIMS [received by the International Bureau on 27 May 2008 (27.05.2008)]
1. An apparatus for cutting tissue, said apparatus comprising: a shaft having a first end and a second end opposite said first end, said first end forming a handle for said apparatus; a flat portion formed adjacent said second end of said shaft and angled relative to said shaft, said flat portion having a generally triangular indentation; a blade for cutting the tissue, said blade being secured within said triangular indentation of said flat portion, said blade having a V-shaped cutout formed by inner sharpened portions for engaging the tissue; and a hoi low channel for optical visualization of the tissue.
2. The apparatus as set forth in claim 1 wherein said flat portion extends at an obtuse angle relative to said shaft.
3. The apparatus as set forth in claim 2 wherein said obtuse angle is approximately 100 degrees.
4. (cancelled)
5. The apparatus as set forth in claim 1 further including an optical visualization device disposed at least partially within said hollow channel. -10-
6. The apparatus as set forth in claim 5 wherein said optical visualization device includes a camera, a light source, and a fiber optic bundle disposed within said hollow channel.
7. The apparatus as set forth in claim 6 wherein said hollow channel is formed integrally with said shaft and said flat portion.
8. The apparatus as set forth in claim 1 wherein said blade is constructed integrally with said flat portion.
9. The apparatus as set forth in claim 1 wherein said blade is removably secured within a recess of said flat portion.
10. The apparatus as set forth in claim 1 wherein said blade is fixedly secured to said flat portion.
11-20. (cancelled)
