Surgical Saw Blade
First Claim
1. An apparatus for use in surgery comprising:
- a surgical saw with a drive mechanism;
a cutting blade attached to the drive mechanism;
the cutting blade having a support structure holding a plurality of teeth;
the teeth having a cutting edge extending partially across the width of the cutting blade;
the teeth disposed along a radial edge of the longitudinal axis; and
a gullet formed between adjacent teeth interconnecting all teeth along the longitudinal axis.

Abstract
This invention discloses methods and devices using an improved surgical saw blade for resecting bone tissue during surgical procedures. The surgical saw blade may be used on oscillating, reciprocating, rotary or vibrational surgical saws. The disclosure describes the use of a cutting blade to resect hone tissue without excessive temperature rise during typical surgical procedures. The cutting blade provides a self-clearing design that includes at least two teeth disposed to prevent accumulation of bone chips within the proximity of the teeth. The design of the cutting blade allows the mechanical motion of the blade and other interactions between the blade and the tissue to remove accumulated bone chips and prevent excessive temperature rise.

12. An apparatus for use in surgery comprising:
-
a drive mechanism communicating with a cutting blade; the cutting blade having a high frequency vibration along the longitudinal axis; the cutting blade also having a support structure holding a plurality of teeth; the teeth having a cutting edge extending partially across the width of the cutting blade; the teeth disposed along a radial edge of the longitudinal axis; and a gullet formed between adjacent teeth interconnecting all teeth along the longitudinal axis.

13. A method of surgery on bone tissue comprising the steps of;
-
generating an oscillating motion with a surgical saw; transmitting the oscillating motion to a cutting blade connected to the surgical saw; vibrating the cutting blade sufficiently to form a kerf; ejecting bone tissue from the kerf using the vibrating cutting blade transmitting the vibrations from the cutting blade; and using the vibrating cutting blade to dislodge bone tissue from the cutting blade for a self-cleaning blade. - View Dependent Claims (14, 15, 16)

17. A self-clearing cutting blade for use in surgery comprising:
-
the cutting blade disposed along a longitudinal axis; the cutting blade having a support structure holding a plurality of teeth; the teeth disposed along a radial edge of the longitudinal axis; the teeth having a cutting edge extending partially across the width of the cutting blade; adjacent teeth cooperating to form a kerf; and a gullet formed between adjacent teeth interconnecting all teeth along the longitudinal axis.
