ATTORNEY. 2,106,151 Patented Jan. 18, 1938 UNITED STATES PATENT OFFICE 2,106,151 SURGICAL LEG SPLINT Earl E. Longfellow, Warsaw, Ind., assignor to Harry Herschel Leiter, Warsaw, Ind. Application November 16, 1935, Serial No. 50,169 4 Claims. (Cl. 128—84) This invention relates to improvements in sur tion of the rod 3 that projects upwardly from gical leg splints of a similar type to that set forth in my previous application, Ser. No. 720,581, now Patent No. 2,069,721, but di?ering therefrom the cross-head is threaded and has thereon an adjusting nut I3 located beneath the lower end of the guide [2 so that by turning the adjusting 5 in several particulars. nut the frame ‘I is longitudinally moved with re- '5 One of the objects of the present invention is the provision in a splint that has members that are respectively applied to an uninjured leg and the injured leg of a patient, of mechanism to per10 'mit rotative adjustment of both of said members [as Well as relative longitudinal adjustment spect to said rods in opposition to the spring 9. The upper end of the frame 1 arcuate and has secured thereon strip constituting a stirrup l4 that fastenedlto the frame preferably thereof. _ Another object is to provide a splint having members for connection with the uninjured and '15 injured legs, having stirrups that are readily detachable from said members. Other objects and advantages of the invention appear in the following description. An illustrative embodiment of the invention is 20 shown in the accompanying drawing, in which:— Fig. 1 is a front elevation of a structure in which the invention is embodied, a portion being broken away; and Fig. 2 is a top plan view projected from Fig. 1, 25 certain parts being in horizontal section. The illustrative embodiment of the invention includes in its structure a cross-head I provided at the ends thereof with corresponding rods 2 and 3, which rods extend in parallel relation with 30 each other and. at right angles with respect to the length of the cross-head. The lower ends of said rods project downwardly ‘from said cross-head and are threaded to receive corresponding nuts 4, and have mounted thereon between said nuts 35 and the cross-head a beam 5 that extends laterally in one direction. The beam has in one end portion thereof oppositely disposed arcuate slots 6 through which the lower ends of the rods 2 screws l5. the action of preferably is an U-shaped is detachably 10 by means of ‘ The. laterally extending end portion of the beam 5 has adjustably mounted thereon a bracket l6, there being a series of spaced apertures ll in ‘15 the beam for the reception of a securing bolt 18 that extends through the bracket and one or an other of said apertures._ The slot I9 in the bracket through which the beam extends is suf ?ciently large as to permit of limited tilting 20‘ movement upon the axis of the bolt and also the lower end of said bracket, being closed, prevents inadvertent disconnection of the bracket from the beam when the bolt I8 is removed to permit adjustments therebetween. The upper end of 25 the'bracket has a threaded stud 20 upon which is adjustably secured a clamp 2| provided with a tightening screw 22 to secure the clamp against rotative movement relative to the stud. The clamp has at its upper end an arcuate extension 30 23 to the sides of which are removably secured corresponding separable strips 24 that extend in parallel relation with each other and constitute a second stirrup. The strips 24 are individually removable from said extension upon removal of 35 screws 25 by which said strips are secured to the extension on the outer faces thereof. Each strip has made therein a series of perforations 26 for and 3 respectively extend whereby the cross-head the reception therethrough of a skeletal pin 21 40 is adapted to be adjusted rotatively upon an axis at right angles thereto relative to the beam. Upon the end portions of the rods 2 and 3 that project upwardly from the cross-head is mounted a frame 1 that is slidable thereon longitudinal45 ly with respect to said rods. The frame 1 has a hook 8 adjacent its upper end that projects laterally from its outermost side and has connection with one end of a retracting spring 9. The cross-head I also has a projecting hook II] that 50 has connection with the outer end of said spring, which spring acts to restrain movement of the frame on said rods in the direction away from the cross-head. The frame has at its sides corresponding elongated guides H and I2 into which 55 said rods loosely extend respectively. That por- which is adapted to be inserted transversely with respect to said stirrup. o emu-On p In use, the stirrup I4 is placed astride of the lower extremity of the uninjured leg of the patient (not shown). The sides of the stirrup are then preferably encased together with the uninjured leg by applying a plaster cast in the usual man ner. The frame I is thus ?rmly held attached to the uninjured leg. The strips 24 of the other stirrup are then placed astride of the injured leg and, if the surgeon elects to apply skeletal treat ment, a pin preferably of the Steinmann type is inserted through the perforations 26 in said strips and the injured leg so as to engage the bone frag- 40 45 50 . 55 2 2,106,151 ment therein. A plaster cast is then applied so as to encase the strips, the projecting ends of the pin and the injured leg, in the usual manner. The bracket I6 is then adjusted upon the beam to such position as to afford the desired angulation or spread between the legs of the patient. The. clamp 2| is then loosened on the stud by turning said frame, a bracket adjustably secured on said beam, a clamp rotatively adjustable on said bracket provided with an extension, and strips removably secured respectively upon the outer sides of said extension constituting a second the screw 22 to permit movement of the clamp to plicable respectively to uninjured and injured legs secure the desired rotative adjustment of the leg, 10 after which the screw is tightened so that ad justment of the leg is secured in that respect. After the legs have been secured in their re-_ stirrup. 2. In a surgical splint having members ap of a patient, a frame provided with a stirrup and having longitudinal parallel guides, a cross-head 10 having parallel rods that extend into said guides to permit longitudinal adjustment of said frame spective stirrups and the plaster casts have set. thereon, a beam connected with said cross-head The nuts 4 are loosened so as to permit adjust so as to permit relative adjustment of said cross 15 ,ment of the cross-head with respect to the beam 5. In this manner extroversion and introversion maneuvering it into a good and comfortable posi tion, after which the nuts 4 are tightened. Then, head and beam transversely to said rods, means for ‘securing said beam in its adjusted positions, means for moving and securing said frame ad justably on said rods relative to said cross-head, a retracting spring connecting said frame and by turning the adjusting nut l3, movement is im cross-head, a bracket secured on said beam, a 20 parted to the cross-head I and the beam 5 away from the frame 1 in opposition to the restraint of the spring 9, and in this manner is applied exten sion with respect to the injured leg and counter clamp rotatively adjustable on said bracket, and strips removably secured in connection with said bracket constituting a second stirrup. 3. In a surgical splint having members applica ble respectively to uninjured and injured legs of a 25 patient, a frame provided with a stirrup and hav ing longitudinal parallel guides, a cross-head hav ing parallel rods that extend into said guides to permit longitudinal adjustment of said‘ frame thereon, a beam connected with said cross-head of the uninjured leg is readily accomplished by extension with respect to the uninjured leg. A valuable feature of the invention is the ad justments of the supporting members for the stirrups with respect to their connecting beam that a?'ords advantageous positioning of the un 30 injured as well as the injured leg. And another feature of value is that the strips that form the stirrups are connected with the frame 1 and extension 23 respectively in such manner as to admit of their detachment there from without discomforture to the patient. I claim:— 1. In a surgical splint having members applica ble respectively to an uninjured and injured leg of a patient, a cross-head having parallel rods lo 40 cated respectively at its ends that extend at right angles thereto, a beam provided with arcuate slots through which the lower ends of said rods ex tend and permit relative adjustment of said cross-head and beam transversely to said rods, means for securing said beam in its adjusted posi tions, a frame having guides at its sides into which the upper end portions of said rods slidably ex tend, an adjusting nut having threaded relation with one of said rods located between said cross head and frame, a retracting spring the ends of which are connected respectively with said cross head and frame, a stirrup removably secured to so as to permit relative adjustment of said cross head and beam transversely to said rods, means for securing said beam in its adjusted positions, means for moving and securing said frame ad justably on said rods relative to said cross-head, and a second stirrup having an adjustable con nection with said beam. ‘ 4. A surgical splint applicable to uninjured and injured legs of a patient, said splint having a member including a stirrup for attachment to the “ 40 uninjured leg and provided with a laterally ex tending beam, another member including a stirrup for attachment to the injured leg and provided with a supporting bracket therefor, said bracket having an opening therein, through which said beam extends, proportioned so as to permit limit ed tilting movement of said bracket on said beam, the bottom of said bracket being closed to prevent inadvertent disconnection of said bracket from said beam, and means for securing said bracket “59”” adjustably on said beam.
