Abstract

A cutting device is disclosed. The cutting device has a body member having a cavity that extends from an opening at a front end portion of the body member toward a back end portion of the body member. The cutting member also has a cutting member partially disposed in a first portion of the cavity, and an insert member disposed in a second portion of the cavity. The cavity narrows in a direction extending from the front end portion toward the back end portion. A width of the first portion of the cavity is greater than a width of the second portion of the cavity.

First claim

What is claimed is:

1. A cutting device, comprising:
a body member having a cavity that extends from an opening at a front end portion of the body member toward a back end portion of the body member;
a cutting member partially disposed in a first portion of the cavity; and
an insert member disposed in a second portion of the cavity;
wherein the cavity narrows in a direction extending from the front end portion toward the back end portion;
wherein a width of the first portion of the cavity is greater than a width of the second portion of the cavity; and
wherein the cavity is completely surrounded by wall portions of the body member.

2. The cutting device of claim 1 , wherein the insert member is tapered.

3. The cutting device of claim 1 , wherein the insert member is tapered in the direction extending from the front end portion toward the back end portion.

4. The cutting device of claim 1 , wherein a width of the cutting member is greater than a width of the insert member.

5. The cutting device of claim 1 , wherein a length of the cutting member is greater than a length of the insert member.

6. The cutting device of claim 1 , wherein an inserted length of the cutting member that is disposed in the cavity is greater than or equal to an exposed length of the cutting member that protrudes from the cavity.

7. The cutting device of claim 1 , wherein the cutting member is formed from ceramic material.

8. The cutting device of claim 1 , wherein the cutting device is a disposable surgical scalpel.

9. The cutting device of claim 1 , wherein the cavity narrows in the direction extending from the front end portion toward the back end portion at a taper angle of between about 0.5° and about 2.5°.

10. The cutting device of claim 9 , wherein a top wall of the wall portions of the body member is tapered.

11. The cutting device of claim 1 , wherein the insert member has a thickness of between about 0.1 mm and about 2 mm.

12. A cutting device, comprising:
a body member having a cavity that extends from an opening at a front end portion of the body member toward a back end portion of the body member;
a cutting member partially disposed in a first portion of the cavity; and
an insert member disposed in a second portion of the cavity;
wherein the cavity narrows in a direction extending from the front end portion toward the back end portion;
wherein the insert member is tapered in the direction extending from the front end portion toward the back end portion; and
wherein the insert member is disposed between the cutting member on a first side and a wall of the body member on a second side that is opposite to the first side.

13. The cutting device of claim 12 , wherein a width of the first portion of the cavity is greater than a width of the second portion of the cavity.

14. The cutting device of claim 12 , wherein the cutting member is formed from Zirconium Oxide.

15. The cutting device of claim 12 , further comprising a cover that is removably attachable to the front end portion and the back end portion.

16. The cutting device of claim 12 , wherein the cutting device is a disposable scalpel.

17. The cutting device of claim 12 , wherein the insert member is a plastic sheet member.

18. A scalpel, comprising:
a scalpel body member having a cavity that extends from an opening at a front end portion of the scalpel body member toward a back end portion of the scalpel body member;
a scalpel blade partially disposed in a first portion of the cavity; and
a plastic sheet member disposed in a second portion of the cavity;
wherein the cavity narrows in a direction extending from the front end portion toward the back end portion;
wherein a width of the first portion of the cavity is greater than a width of the second portion of the cavity; and
wherein the cavity is completely surrounded by wall portions of the scalpel body member.

19. The scalpel of claim 18 , wherein a total length of the scalpel body member is between about 4 times and about 6 times of a length of the cavity.
