Sept. 6, 1960 G. B. SULLIVAN SURGICAL SAW Filed Sept. 22, 1955 SIJ RGICAL SAW Gregory B. Sullivan, 1521 W. 89th St., Chicago, Ill.

Filed Sept. 22, 1955, S61. N0. 535,849

6 Claims. (Cl. 128-317) The invention relates generally to cutting tools and more particularly to a surgeons cutting saw.

In the past, surgical instruments of the type here involved have been constructed generally similar toscalpels and the like, utilizing the same type of straight, smooth handle members of metal, with the teeth generally being formed similarly to those of a rasp or the like. Such instruments produce their main or complete cutting action when pushed by the surgeon in a direction from the handle toward the blade. Obviously, cutting by means of a pushing action may be quite dangerous, particularly when cutting on the head, as for example, when cutting bone in the nasal passages, etc., a use to which the present invention is particularly adapted. In such case a slip of the blade while force is applied in a pushing direction could easily result in the blade penetrating the brain with fatal consequences. It will also be appreciated that during the course of an operation, the surgeons rubber gloves, and thus the handles of the instruments may be covered with blood, increasing the possibility of slippage and other accidents.

The present invention therefore has among its objects, the production of a surgical instrument which eliminates the disadvantages above referred to, an instrument constructed in accordance with the present invention providing the maximum possible safety to the patient, together with maximum ease and flexibility of operation to the surgeon, and which is self-debriding.

More specifically the invention has among its objects and advantages, the production of such an instrument which places the surgeons hand in a logical, natural and thus comfortable position, with the instrument being carefully balanced and designed to be firmly gripped without undue pressure thereon, whereby fatigue and muscular strain are reduced to a minimum.

Another object of the invention is the production of such an instrument which derives its cutting action from a pulling action toward the surgeon instead of a pushing action, whereby fatal or serious injuries as a result of accidental disengagement of the instrument from the bone or other material being cut, is completely eliminated.

A further object of the invention is the production of such an instrument which is universal in use, either in the right or the left hand, constructed of material which may be readily sterilized, the handle being provided with a novel, non-slipping surface and the blade being of highly eflicient metal, constructed to be readily detached from the handle whereby blades may be readily replaced Without replacement of the handle.

A further object is the production of such an instrument which is exceedingly simple in construction, durable in use, and relatively inexpensive to manufacture.

Many other objects and advantages of the construction herein shown and described will be obvious to those sldlled in the art from the disclosure herein given.

To this end my invention consists in the novel construction, arrangement and combination of parts herein shown and described and more particularly pointed out in the appended claims.

In the drawings wherein like reference characters indicate like or corresponding parts:

Fig. 1 is a side elevation of a surgical saw embodying the present invention;

Fig. 2 is a front elevational view of the saw illustrated in Fig. 1,- indicating in dotted lines the approximate position of the hand when grasping the saw;

Fig. 3 is a more or less exploded view of the details of the chuck and blade structure with portions thereof broken away; and

Fig. 4 is a side elevation of a surgical saw embodying the invention, utilizing an in-line handle grip.

Referring to the drawings and particularly to Figs. 1, 2, and 3, the reference numeral 1 indicates generally a surgical cutting instrument having a handle member, indicated generally by the numeral 2, the latter being provided with a chuck structure indicated generally by the numeral 3 and adapted to receive and support a blade member indicated generally by the numeral 4.

The handle 2 may be formed from any suitable material, as for example, an acrylic plastic that will withstand sterilizing temperatures. In the embodiment illus trated, the handle 2 is generally crescent-shaped having a convex outer edge 5, and a generally concave inner edge 6, the latter being provided with outwardly extending projections 7 defining a finger gripping portion Sb therebetween and portions 8a and at each side thereof. The opposite faces 9 of the handle are recessed as indicated at 11 whereby the handle will closely fit the hand when gripped as indicated in dotted lines in Fig. 2 with the forefinger positioned adjacent the portion 8a, the index finger adjacent the portion 8b and the ring finger adjacent the portion 80.

Extending from the end of the handle 2 adjacent the portion 8c is a chuck structure 3, the latter having a threaded stem 12 positioned in the generally rectangularshaped end 13 of the handle, with the two, in the embodiment illustrated, being threaded together and locked in position by rivets 14. The stem 12 may be provided with tapered free end portions 15 as illustrated in Fig. 3, and is formed with a diametrical, bifurcating slot 1.6 therein adapted to receive a portion of the blade mem her '4. A collar 17 may be threaded on the stem 12, the collar having an internal shoulder 18 therein engageable with the tapered portions 15 of the bifurcated end of the stem, whereby the portions 15 are urged toward one another to clamp an object inserted therebetween. If desired, the outer face of the collar 17 may be knurled or otherwise suitably formed to provide a gripping surface.

When held in the hand as previously described, the little finger may overlap the ring finger and rest on the chuck 3, while the thumb may be positioned on the forefinger as indicated in Fig. 2 or rest upon the upper end edge of the handle as viewed in Figs. 1 and 2.

To facilitate gripping of the handle member 2 and preventing Slipping, particularly if the hand is wet or bloody, the handle member is preferably formed with numerous small serrations or grooves lfi-substantially throughout the gripping areas thereof, the grooves generally extending in appropriate direct-ions whereby they are transverse to the normal direction of slippage, as is believed clear from Figs. 1 and 2 of the drawings.

In the embodiment illustrated in Figs. 1 to 3, the blade member 4'is of offset design having a shank portion 21 of a size to be received in the slot 16 in the stem- 12, and a blade portion 22 illustrated as being formed from separate stock and secured to the remainder of the member byv suitable means such as brazing, etc., with the blade portion being of thinmaterial and .extending on and .parallel with the axis of the portion 21 but 3 spaced therefrom and operatively connected by an intermediate portion 23, shown as integrally formed with the shank 21.

As illustrated in Fig. l, the plane of the blade membet 4, and thus that of the slot 16 may be inclined with respect to the general plane of handle member 2 as indicated in Fig. 1, whereby such plane more or less bisects the clenched portion of the hand and fingers. This construction provides substantially uniform clearance on oppositesides of the hand.

If desired, particularly where the blade is not so inilin gd, the instrument may be used equally well in either The blade portion 22, illustrated in Fig. 3 is provided with cutting teeth 24 in the outer edge thereof, the teeth facing generally in the direction of the shank end thereof whereby cutting action is effected by drawing the blade; across an object as distinguished from pushing the blade. The opposite edge of the blade member is curved adjacent the free end of the blade as indicatied at 25 to form a blunt, generally pointed free en The instrument just described is particularly eiiicient in nasal operations, etc., where bone is to be removed from adjacent the nasal passages, and as the cutting seam is achieved by drawing the blade away from the patient, there is no danger of penetrating the brain cavity if the blade should slip from the bone.

It will also be appreciated that the instrument is self-debriding, whereby the severed tissue, etc, is moved outwardly instead of inwardly as occurs with prior instruments.

In the embodiment illustrated in Fig. 4, the general construction illustrated in Figs. 1 to 3 is employed, this embodiment, however, utilizing a straight blade member and in-line handle structure whereby the blade portion 22' and shank portion 21" of the blade members 4, the chuck structure 3 and handle 2 all substantially lie on a common axis with the other details of construction following those previously described. This construction may be advantageous in certain applications, and if desired, as the shank portions 21 and 21 are of like cross-sectional dimensions they are interchangeable in the handle members 2, and 2f.

Both of the embodiments illustrated are nicely balanced and due to the novel arrangement may be used without undue gripping pressure, whereby fatigue and muscular strain are reduced to a minimum. Likewise, when a blade becomes dull it may readily be replaced with a new blade achieving maximum efficiency with low maintenance cost as distinguished from present tools of integral construction requiring periodic sharpening and complete discarding when the blade can no longer be sharpened.

While I have illustrated various types of surgical saws, it will be apparent to those skilled in the art that the present invention may be utilized with other cutting elements as well as the specific saws illustrated.

Having thus described my invention, it is obvious that various immaterial modifications may be made in the same without departing from the spirit of my invention; hence, I do not wish to be understood as limiting myself to the exact form, construction, arrangement and combination of parts herein shown and described, or

uses mentioned. V a
