Abstract

A surgical saw for cutting bone that can be used with ease in tight places yet maintain sufficient cutting power. The surgical saw 10 has a flexible linear body made of twisted stainless steel wire and cutting parts formed on the flexible linear body. The cutting parts are made of abrasive material affixed to the flexible linear body 12a alternating with portions of the flexible linear body with no abrasive particles 12b. Auxiliary cutting parts 13 of lesser cutting power may be provided along both lateral sides of each of the cutting parts 12.

Claims

1. a surgical saw comprising:

a flexible linear body; and

one or more than two cutting parts adapted to cut hard tissue such as bone, each one cutting part comprised of two parts alternatively provided on the flexible linear body, one part wherein abrasive particles are affixed to the flexible linear body and another part wherein no abrasive particles are affixed to the flexible linear body.

2. The surgical saw according to claim 1, wherein the flexible linear body is stranded wire or mesh line.

9. The surgical saw according to claim 1, wherein the cutting parts are formed by affixing abrasive particles to the linear body,

the abrasive particles being diamond or cubic boron nitride (CBN),

the abrasive particles affixed to the linear body by nickel welding.

3. A surgical saw comprising:

a flexible linear body;

cutting parts adapted to cut hard tissue such as bone affixed to portions of the flexible linear body; and

auxiliary cutting parts with lesser cutting power than the cutting parts affixed to other portions of the flexible linear body.

4. The surgical saw according to claim 3, wherein the auxiliary cutting parts are formed on both ends of the cutting parts.

5. The surgical saw according to claim 3, wherein the flexible linear body is a single strand of metal wire,

a plurality of spaced grooves is provided on the flexible linear body in the direction of the width of the flexible linear body so as to form the cutting parts therebetween,

a plurality of spaced grooves is provided on both ends of the flexible linear body in the direction of the width of the flexible linear body so as to form the auxiliary cutting parts therebetween, the grooves gently angled along both lateral sides of each such auxiliary cutting part,

the auxiliary cutting parts formed on both ends of the cutting part, at both ends of the flexible linear body.

6. The surgical saw according to claim 3, wherein the flexible linear body is stranded wire or mesh line.

8. The surgical saw according to claim 6, wherein the flexible linear body is stranded wire or mesh line.

7. A surgical saw comprising:

a flexible linear body; and

cutting parts adapted to cut hard tissue such as bone affixed to portions of the flexible linear body,

wherein at least the cutting parts of the flexible linear body are coated with a lubricating material.
