SURGICAL INSTRUMENT Filed Nov. 25, 1955 IN V EN TOR.
United States Patent SURGICAL INSTRUMENT Kenneth R. Rowe, Kalamazoo, Mich., assiguor to Orthopedic Frame Company, Kalamazoo, Mich.
Application November 25, 1953, Serial No. 394,427
8 Claims. (Cl. 128317) This invention relates to improvements in surgical saws or implements.
The principle objects of this invention are:
First, to provide a power driven oscillating cutting implement of such small size as to be highly practical in performing surgery in confined spaces.
Second, to provide a rapidly oscillating saw on a long narrow mounting that permits the saw to be inserted into the nasal passages for cutting boney structure of the nose without damaging the soft membranes of the nose.
Third, to provide a surgical implement which is simple to construct and use and which is light and small enough for its intended purpose.
Fourth, to provide a novel oscillating drive for the blade of a surgical implement.
Other objects and advantages of the invention will be apparent from the consideration of the following description and claims.
The drawings, of which there is one sheet, illustrate a highly practical form of the implement.
Fig. 1 is a fragmentary side elevational view of the implement with portions broken away in cross section.
Fig. 2 is a fragmentary exploded view of elements of the implement with the elements shown in longitudinal cross section.
Fig. 3 is an enlarged fragmentary longitudinal cross sectional view through the outer end of the implement taken along the plane of the line 3--3 in Fig. 4.
Fig. 4 is an enlarged fragmentary longitudinal cross sectional view taken at right angles to Fig. 3 and along the plane of the line 4-4 in Fig. 3.
Fig. 5 is an enlarged view similar to Fig. 3 but illustrates the implement blade in its extreme oscillated positions.
The implement comprises a cylindrical body 1 having an internally threaded outer end 2 which receives a head 3. A long narrow tubular neck 4 is formed on the outer end of the head and is diametrically and longitudinally slotted as at 5. The inner or lower end of the body as illustrated in the drawings is internally threaded as at 6 to receive a coupling member 7 for a fiexible drive shaft 8 which extends to and is driven by a high speed motor 9.
The interior of the body 1 is provided with bearings 10 which rotatably support a drive shaft 11 extending axially through the body. The inner or lower end of the drive shaft extends from the body and is longitudinally slotted as at 12 to be received in the coupling 7 and be connected to the rotating element of the flexible shaft 8. The opposite end of the drive shaft 11 consists of an elongated rotating rod 13 having an axially beveled outer end 14. The rod 13 extends in laterally supported relation through the elongated neck 4 and projects into the slot 5 as is most clearly illustrated in Figs. 3 to 5.
The sides of the tube 4 on opposite sides of the slot 5 are pierced to receive a hardened rivet 15 that is permanently fixed in the sides of the tube and bridges the slot 5. The rivet 15 intersects the axis of rotation of the rod 13 at right angles and forms a pivotal support for a segmental saw blade 16. The sides of the blade 16 have thickened hub portions 17 which laterally support the blade from the inner sides of the slot 5. The inner side edge of the blade 16 is provided with a chordally extending portion 18 disposed generally perpendicular to the axis of the neck 4 and rod 13. This edge 18 is further axially beveled on each side as at 19 as is best illustrated in Fig. 4. The edge 18 is positioned by the pivot 15 in engagement with the beveled end of the rod 13.
2,702,550 Patented Feb. 22, 1955 "ice When the beveled end of the drive rod 13 is disposed with the bevel facing to either side of the plane of the blade 16 the bevel of the drive rod meets with the bevel 19 of the chordal edge of the blade and the blade assumes a neutral or immediate position as is illustrated in Figs. 3 and 4. However, as the projecting tip of the beveled end of the drive rod rotates into upwardly or downwardly facing position the projecting edge of the drive rod moves across the chordal edge 18 of the blade and tilts the edge forwardly or backwardly as is shown in Fig. 5 to oscillate the blade.
Desirably the motor 9 or other driving element for the shaft 11 is designed to operate at 12,000 R. P. M. so that the blade will oscillate or reverse its direction of movement 24,000 times per minute. The relatively short stroke of the oscillating blade when the blade is toothed prevents it from cutting or damaging the soft tissues which yield or move with the teeth rather than being cut by the teeth. However, the rapidly oscillating movement of the blade functions to cut solid boney structure with ease when the blade is pressed against the hard surface.
It is deemed desirable that the shaft 11 should rotate at least 6,500 R. P. M. when the implement is used to cut bone or boney structure.
