MICHAEL DEGEORGE ATTORNEY TRACTION SPLINT ASSEMBLY This invention relates to the art of surgical splints, and more particularly concerns an improved adjustable traction splint.

Traction splints assemblies known heretofore have had a number of features which made their use and adjustment difficult and contributed to patient discomfort. Some required elastic bandages to bind patients limbs, others required use of loose towels, pillows, or loose foam rubber or felt pads. These frequently shifted when in use or pressed sensitive parts of limbs to cause extreme patient discomfort. Often loose clips were used to hold the loose pads in place, and these often fell off, or shifted to loose their effectiveness. Moreover the impaired limb could not be X-rayed in the splint assemblies nor could the assembly be sterilized easily.

The present invention is directed at overcoming the above and other difficulties and disadvantages of prior traction splints, particularly those used for immobilized legs of bedridden patients.

According to the invention, there is provided a traction splint assembly having an L-shaped forward calf and foot supporting section, and a rear thigh supporting section, each section basically comprising a shell having a trough-like configuration. The shells are lined by a thick resilient pad which is removably cemented in place, so it may be discarded after use. The shells are made of strong, lightweight metal or a dimensionally stable polyester plastic reinforced by fiberglass to insure toughness and durability. Other plastic materials may be used at somewhat greater cost than the fiberglass plastic. The sections are joined by a balanced hinge assembly which permits relative longitudinal and angular adjustment of the two sections.

It is therefore, a principal object of the present invention to provide a traction splint assembly which is easily adjustable in length to fit patients of different heights.

It is a further object of the present invention to provide a traction splint assembly which is capable of balanced adjustment thereby avoiding twisting and lateral shifting. a

It is another object of the present invention to provide a traction splint assembly which may be autoclaved to insure sterilization.

It is another object of the present invention to provide a traction splint assembly which is lightweight and relatively simple in construction.

These and other objects and many of the attendant advantages of this invention will be readily appreciated as the same becomes better understood by reference to the following detailed description when considered in connection with the accompanying drawings in which:

FIG. 1 is a side view of the traction splint assembly embodying any invention;

FIG. 2 is an enlarged cross-sectional view taken along line 2-2 of FIG. 1;

FIG. 3 is a fragmentary longitudinal sectional view taken along line 3-3 of FIG. 2;

FIG. 4 is an enlarged fragmentary horizontal sectional view taken along line 4-4 of FIG. 1;

FIG. 5 is an exploded perspective view showing parts of my traction splint assembly; and

FIG. 6 is a perspective view ofa support strap in open position.

Referring now to the drawings wherein like reference characters designate like or corresponding parts throughout, there is illustrated in FIGS. 1 through 4, an

articulated traction splint assembly generally designed as reference numeral 10 and comprising a forward section 12 which supports a patient's calf and foot, and a 5 rear section 14 which supports the patients thigh. The

sections

12 and 14 are pivotally and slidably joined by a hinge assembly 16. v

The forward section 12 includes an outer L-shaped shell 17 formed with an elongated trough 18 open at the top 19 to support a patients calf and ankle and foot. The front end of the shell 17 is formed with an upright channel 22 to receive the patients foot. A cutout 24 is formed in the shell 17 at the juncture of the trough 18 and the channel 22 where the patients heel and ankle will be located and supported by a felt pad 25. The entire shell 17 is lined with the one-piece, thickfibrous felt pad 25 removably attached to the shell interior by a suitable adhesive. Upper edges of the pad 25 project outwardly beyond the upper edges of the shell 17.

Ventilation holes

26 and 27 are formed in the bottom of the trough l8 and at the end of the channel 22. A pair of eyebolts 28 are set in holes in the channel 22 for selectively receiving an S-hook 30 to which a suspension rope 32 is attached. Each of the eyebolts 28 are secured by a pair of

washers

31, 33 and a nut 34.

The rear section I4 includes an outer shell 36 formed as a trough open at the top and both ends. The shell 36 is wider but shorter than the shell 17 and is shaped to receive the lower part of the thigh of a patient. Ventilation holes 38 are formed in the bottom of the shell 36 which may be lined with a thick resilient pad 40 snugly fitted in the shell and removably secured in place by an adhesive. The pad 40 extends outwardly of the shell 36 at both ends and upwardly beyond upper edges 42. A pair of slots 44 formed in the shell 36 at each side near the upper edges 42 are each adapted to receive a strap 45. There are two identical straps ateach side.

Each strap 45 as best shown in FIG. 6, has a buckle 46 at one end to engage the other end of the strap which is free. A flattened ring 48 holds the free end of the strap and another ring 50 may be engaged by a traction rope 52 (indicated by dotted lines in FIG. 1). The rope 52 can be secured to the rings 50 of all of the four straps 45 and brought together to form a sling.

The front and

rear sections

12, 14 of the splint assembly 10 can be adjusted angularly and lengthwise with respect to each other by means of the hinge assembly 16. At each side of the splint assembly 10 are two

hinge bars

60, 62. The hinge bar is a straight flat member with a long central slot 64 extending longitudinally and terminating just short of a hole 66 (FIG. 5) near the bottom end 67. The hinge bar 62 is also a straight flat member with long central slot 63, which terminates at the bottom in an arcuate, coplanar foot portion 68. This acuate foot portion has holes 70 to receive a plurality of registering holes 74 formed in the upper rear corner of the trough 18. The bolts 72 are each secured by a nut 75 and a pair of

washers

76,77. The hinge bars 62 are thus fixed in angular position with respect to trough 18 as clearly shown in FIG. 1. The hinge bars 60 are pivotally attached to upper front corners of the trough 36 by a bolt 78 inserted through a registering hole 79 on each side of the trough 36 and secured by a nut 80 and a pair of washers 81, 82. The

bars

60, 62 are disposed in abutment, in crossed arrangement. A bolt 84 is inserted through the

insecting slots

63, 64 and extends through an aperture 89 in each of a pair of rectangular

flanged guide plates

86, 88 located respectively on the outer sides of

bars

60, 62. The bolt 84 extends through the holes 89 in these plates. Each bolt is secured by a washer 92 and a nut 94. Protruding portions 96 which are integral with the plates 89 engage the heads of the bolts 84 and prevent their rotation.

By the hinge arrangement described, it will be appar ent that the bars 64 may be pivotally adjusted with respect to thigh supporting section 14. The hinge bars may be slidably and rotatably adjusted with respect to each other to adjust the longitudinal spacing between the front and rear sections l2, l4, and the relative angular position of the sections. A traction rope 98 may be attached to the bars 62, or if desired a conventional bow hinge may be connected by the traction rope 98 to the bars 62 for suspending the splint in traction at the hinge assembly 16.

The shell-

like troughs

18 and 36 may be made of a strong, tough, light-weight, chemically stable material which is transparent to X-rays, and which can be autoclaved to sterilize it. A suitable material for this purpose is polyester plastic reinforced with fiberglass. This material is relatively inexpensive. It may easily be molded to a desired form and will retain its form in spite of severe stresses and strains applied to it. Other comparable reinforced plastic material as well as metals may also be used.

It will be apparent now that the traction leg splint desired, embodies all the features and characteristics essential to a satisfactory splint. The splint has been proven by extensive testing to afford patients in leg traction greater comfort than has been possible heretofore while simplifying the traction equipment required.

It should be understood that the foregoing relates to only a preferred embodiment of the invention, and that it is intended to cover all changes and modifications of the example of the invention herein chosen for the purposes of the disclosure, which do not constitute departures from the spirit and scope of the invention.
