| 摘要 | A cutting blade for use in cutting off fracture-fixation pins with an oscillating cutting device. At least one elongated aperture with a plurality of hollow-ground saw teeth located on its periphery is provided on the blade to smoothly cut off the fracture-fixation pins. An attachment member is provided on the cutting blade to attach it to the oscillating cutting device. | ||||||
| 权利要求 | 1. A cutting blade for use with an oscillating cutting device in cutting off fracture-fixation pins, said cutting blade comprising: a. a body portion having an attachment member for mounting said body portion onto the oscillating cutting device and having an elongated apeRture spaced away from said attachment member; and b. a cutting portion located around the entire periphery of said elongated aperture for allowing said cutting portion to selectively contact all portions of the circumference of the fracture-fixation pin being cut off to smoothly cut off the fracture-fixation pin. 2. The cutting blade of claim 1 in which said cutting portion consists of a plurality of hollow-ground saw teeth. 3. The cutting blade of claim 2 in which said aperture s located about a curved center line every point of which is equally distant from the center of said attachment member. 4. A cutting blade for use with a oscillating cutting device in cutting off fracture-fixation pins, said cutting blade comprising: a. a body portion having an attachment member for mounting said body portion onto the oscillating cutting device and having an elongated aperture spaced away from said attachment member and located about a curved center line every point of which is equally distant from the center of said attachment member; b. a cutting portion located on the periphery of said elongated aperture for cutting off the fracture-fixation pin, said cutting portion consisting of a plurality of hollowground saw teeth; and c. a trough-like member located on the periphery of said body portion beneath said elongated aperture for catching any filings produced when the pin is being cut off. 5. The cutting blade of claim 4 in which said body portion is circular and includes a plurality of elongated apertures. 6. The cutting blade of claim 5 in which said body portion includes three elongated apertures and in which said attachment member consists of a triangular stud for mounting onto the oscillating cutting device in one of three positions by means of a triangular chuck of the oscillating cutting device. 7. A cutting blade for use with an oscillating cutting device in cutting off fracture-fixation pins, said cutting blade comprising: a. a body portion having an attachment member for mounting said body portion onto the oscillating cutting device and having an elongated aperture located about a curved center line every point of which is equally distant from the center of said attachment means; b. a plurality of hollow-ground saw teeth located on the periphery of said elongated aperture; and c. a trough-like member located on the periphery of said body portion beneath said elongated aperture for catching any filings produced when the pin is being cut off. 8. The cutting blade of claim 7 in which said body portion is circular and includes a plurality of said elongated apertures. 9. The combination with an oscillating cutting device of a cutting blade for use in cutting off fracture-fixation pins, said cutting blade comprising: a. a body portion having an attachment member mounting said body portion onto the oscillating cutting device and having an elongated aperture spaced away from said attachment member; b. a cutting portion located around the entire periphery of said elongated aperture for allowing said cutting portion to selectively contact all portions of the circumference of the fracture-fixation pin being cut off to smoothly cut off the fracture-fixation pin. 10. The combination of claim 9 in which said cutting portion consists of a plurality of hollow-ground saw teeth. 11. The combination with an oscillating cutting device of a cutting blade for use in cutting off fracture-fixation pins, said cutting blade comprising: a. a body portion having an attachment member mounting said body portion onto the ocillating cutting device and having an elongated aperture located about a curved center line every point of which is equally distant from the center of said attachment means; b. a plurality of hollow-ground saw teeth located on the periphery of said elongated aperture; and c. a trough-like member located on the periphery of said body portion beneath saId elongated aperture for catching any filings produced when the pin is being cut off. 12. The combination of claim 11 in which said body portion is circular and includes a plurality of elongated apertures. |
