APPARATUS FOR BINDING FRACTURED BONES.

Specification of Letters Patent.

Patented July 20, 1920.

Application led October 28, 1919. Serial No. 333,968.

T0 all whom t may concern:

Be it known that I, AsA W. COLLINS, a citizen of the United States, residing at San Francisco, in the county of San Francisco and State of California, have invented new and useful Improvements in Apparatus for Binding Fractured Bones, of which the following is a specification.

The object of the present invention is to provide a band for binding fractured bones, and an instrument for applying the same.

In the accompanying drawing, Figure 1 is a perspective view showing the instrument and band in use on a broken bone; Fig. 2 is a view similar to Fig. 1, but showing the instrument in a position different from that in Fig. 1; Fig. 3 is a longitudinal sectional view of the instrument; F ig.' 4L is a plan view of the band; Fig. 5 is a side view of the same; Fig. 6 is a perspective view showing the completed band around a broken bone.

Referring to the drawing, 1 indicates my improved band which is made of a single piece of sheet metal cut to form a rectangular loop 2 and a strip 3 extending from one side of said loop. On the sides of the loop extending transversely to said strip are placed strengthening strips 4;, brazed or otherwise secured thereto.

The band is' placed around the bone, shown at 6, with the strip 3 extending through the loop 2 and said strip is then inserted through a slit 7 in the outer thickened portion 8 of a plate-like finger 9 pivoted by screws 11 within the ends of a long fork 12. After extending through said slit, the strip 3 extends down between the members of said fork into a recess 13 in a nut 14 and is clamped to said nut by a screw 16 screwed into said nut transversely to said fork and having a reduced inner end 17 adapted to enter a hole 18 in the outer end of said strip. A stationary screw 19 extends parallel with said fork and is screwed through said nut, and one end extends through an offset portion 21 of the fork and has on its extreme end a head 22 by which it may be turned.

rIhe finger has outer shoulders 10 adapted to abut against outer shoulders 2O on the support to limit the outward turning movement of the finger, and inner shoulders 23 adapted to abut against inner shoulders 24 on the support to limit the inward turning movement of the finger'.

After the strip is secured to the nut in the manner above described, the strip is drawn into the instrument by' turning the screw, thus causing the nut to travel awa from the plate or finger 9, said plate in the meantime being held firmly against the free end of the band, thus compressing the band very firmly around the bone. When sufficient pressure has been exerted on the fractured bone, the instrument is given a forward movement by pressing upon the head 22, causing the plate 9 to extend at right angles to the main portion of the instrument and bending the strip at the point where it passes through the loop in the band into the form of a hook and securing the strip in the band.

The strip is then cut off close to the band and the instrument is removed from the band. The band is then held firmly around the fractured bone.

I claim l. In means for tightening a band around a fractured bone, said band having a loop and strap extending from one end thereof, a traveling member, means for securing the strap to said traveling member, a screw on which said traveling member travels, means for supporting said screw, and a finger pivoted on said supporting means and having a slot through which said strap extends. Y

2. In means for tightening a band around a fractured bone, said hand having a loop and a strap extending from one end thereof and apertured at its free end, a screw having a free end adapted to pass through said aperture, a traveling member into which said screw is screwed, and having a recess to receive the free end of the strap, a stationary screw in which said traveling member travels, means for supporting said screw bearing, a finger pivoted on said supporting means and having a slot through which said strap extends, and having a shoulder adapted to abut against a shoulder on said support to limit the turning movement of said finger.

ASA W. COLLINS.
