12 Claims. (Cl. 12887) This invention relates to surgical splints, and more particularly to splints intended for application to the upper extremities of the body.

An object of the invention is to provide a novel and improved, surgical splint device which is adapted for use as a combined hand and forearm splint, or which may be easily and quickly converted to constitute either a traction finger splint or a forearm splint.

Another object of the invention is to provide an im proved surgical splint as above characterized, which when converted for use as a finger splint may be readily adjusted or oriented for either right-hand or left-hand use.

Yet another object of the invention is to provide an improved finger splint in accordance with the above, wherein any one or all of the fingers of the hand may be readily immobilized or held inactive, or various combinations of fingers as required, and wherein traction may be applied optionally to such fingers as are considered to require the same.

A still further object of the invention is to provide an improved surgical splint of the above type, which is quickly and completely adjustable to conform it to various sizes and shapes of hands and/or forearms.

A feature of the invention resides in the provision of an improved surgical splint having all of the above features and which is also extremely easy to properly adjust and orient, is strong and sturdy, reliable in use, and of extremely light weight.

Another feature of the invention resides in the provision of an improved, adjustable and convertible surgical splint as above outlined, which is simple in construction and economical to fabricate.

Other features and advantages will hereinafter appear.

In the drawings accompanying this specification, simi lar characters of reference indicate corresponding parts wherever possible in the several views, in which:

Figure 1 is a top, plan View of an improved surgical splint made in accordance with the invention.

Fig. 2 is a side elevatioual view of the splint shown in Fig. 1.

Fig. 3 is a transverse sectional view taken on line 3-3 of Fig. 1.

Fig. 4 is a transverse sectional view taken on line 4-4 of Fig. 1.

Fig. 5 is a top, plan view of the splint converted for hand use only and adapted to the left hand.

Fig. 6 is a plan view of the splint shown in Fig. 5, but adapted for use with the right hand.

Referring to Figs. 1 and 2, the improved surgical splint shown therein comprises an elongate body or main portion indicated generally by the numeral 10, said main portion being in itself extendible or retractible and constituted of a pair of substantially flat,

elongate members

11 and 12 adjustably connected with each other.

To provide for adjustable, extending and retracting movement, the

members

11 and 12 are formed with substantially centrally-disposed, elongate, longitudinally-extending

slots

13 and 14 through which

bolts

15 and 16 pass, said bolts being preferably provided with lock washers 17 and being arranged when tightened to secure the members 11and.12 in various adjusted positions, by which the main portion 10 of the splint may be either lengthened or shortened.

The

body members

11 and 12 may be consitutedof any suitable material, being preferably formed of sheet or strip aluminum alloy of relatively high tensile strength and stiffness. Preferably also, the

members

11 and 12 are provided with elongate, longitudinally-extending embossed ribs or beads 18 adapted to nest with each other whereby an interlocking of the members is effected while at the same time the stiffness or rigidity is greatly increased. By such construction I am enabled to obtain in a surgical splint a very appreciable, desirable rigidity together with lightness of weight.

The improved splint shown in Figs. 1 and 2 further comprises adjustable, transverse portions indicated generaliy by the

numerals

20 and 21, the portion 21 being adapted for engagement with the thicker part of the forearm adjacent the elbow and comprising a pair of

members

22, 23 having

curved extremities

24 and 25 respectively, and having elongate slots 26 and 27 through which bolts 28 may be passed to adjustably secure the

members

22 and 23 together. The bolts 28 also pass through relativelyshort, longitudinally-extended slots 30 in the main member 11, thereby to fasten the transverse portion 21 of the splint to the main portion 10.

It will be understood that, by the provision of the slots 30 in the member 11, the transverse portion 21 may be disposed at a number of different angles with respect to the main portion 10, all such angles however being not greatly different from a right angle. Also, the

members

22 and 23 may be adjustably positioned with respect to each other as well as with respect to the main portion 10 of the splint, thereby to fit the transverse portion 21 to the forearm in a comfortable and effective position.

The transverse portion 20 of the splint comprises

members

32 and 33 having

curved extremities

34 and 35 respectively for engagement with opposite side edges of the hand at the palm thereof. The

members

32 and 33 have

elongate slots

36 and 37 through which bolts 38 pass, said bolts also extending through relatively-short, longitudinally-extended slots 39 in the main member 12 by which the transverse portion 20 of the splint is secured to the main portion 10. It will be understood that adjustment of the

members

32 and 33 maybe effected to enable the portion 20 to be fitted to the width of the palm of the particular hand on which the splint is being used, and that the transverse portion 20 may be also angularly disposed with respect to the main portion 10, as permitted by the slots 39.

Inorder to provide splints for any of the fingers, I employ flat, elongate members or

strips

41, 42 and 43, said strips being arranged to extend along the fingers at the inner sides thereof, and having angularly extended

extremities

44, 45 and 46 respectively. The strips 41-43 may be formed of metal, as for example aluminum alloy, and may be adjustably secured to the transverse portion 20 of the splint by bolts as shown. The strip 41 may be held by a bolt 47 passing through the slot 37 of the member 33. The strip 42 may be held by one of the bolts 38 passing through both of the

slots

36 and 37 of the

members

32 and 33. The strip 43 is held by means of a bolt 48 which passes through a thumb rest in the form of an angle bracket 49 secured to the mem ber 32 by a bolt 50 passing through the slot 36 of the member.

It'will be understood that the

finger splints

41, 42 and 43 may be angularly disposed, as required by the specific tudinally by virtue of the slots therein. After the entire splint has initially been set up, the various bolts may be securely tightened to hold the different components in their adjusted positions, thereby enabling the splint to constitutev a rigid, unitary device.

While only three finger splints havebecn illustrated, itzwill bereadily understood that more or less may be utilized, depending on the requirements. The finger splints for the four fingers of the hand excepting the thumb will be carried by bolts passing through the slots of'the members 32 and/or 33. The thumb splint, of course, is carried by the angle bracket 49.

The angularly bent extremities of the finger splints are perforated or apertures to. admit a wire by which traction maybe effected, suchwire being passed through small holes drilled through the projecting portions of the fingernail, as indicated inFig. 2.

In accordance with the present invention, the combined forearm and hand splint shown in Figs. 1 and 2 may be converted into a splint only for the forearm, or only for the fingers. In the first mentioned case, the finger splints 41-43-together with the thumb rest or angle bracket 49 would not be employed, the transverse portion 20 of the splint being, however, still made to engage the palm as shown. With this form of the invention, the forearm splint is completely adjustable as to length and as to the angularity of the

transverse portions

20 and 21.

Also, in accordance with this invention, the splint shown in Figs. 1 and 2 may be converted to a universal finger splint, by not employing the forearm portion. For this purpose, the body or main portion 10 and transverse portion 21 are omitted, and only the finger splints 4143 used in conjunction with the transverse splint portion 20.

Such an organization is illustrated in Fig. 5, for example, Where the transverse portion 20 mounts the central finger splint 42 and has also the thumb rest or angle bracket 49.

By this invention, the hand splint shown in Fig. may be easily and quickly reversed and converted for righthand use as illustrated in Fig. 6, it being shown for lefthand use in Fig. 5. To accomplish this, the finger splints 42 (or other finger splints, as many as are used) is or are reversed to the position shown in Fig. 6, and also the angle bracket 49 is reversed about its mounting bolt, as shown.

It will be readily understood from the above description that I have provided a very simple, sturdy and advantageous surgical splint device for use with either the right or left hand and/ or forearm. My improved surgical splint is fully adjustable as for length and width of the hand and arm engaging portions, and also for angularity. Finger splints as required are readily provided for, such splints being fully adjustable as for length and angularity, and being capable of applying traction where this is considered desirable. The improved splint of this invention is of extremely light weight while at the same time being strong, sturdy and durable. Moreover, it may be inexpensively fabricated, and will serve to replace more expensive splints having a more limited application.

Variations and modifications may be made within the scope of the claims and portions of the improvements may be used without others.
