18 Claims. (Cl. 128-102) The present invention relates to anatomical supports, and more particularly to trussesadapted for supporting inguinal, femoral and scrotal type ruptures or hernias.

The manner in which any truss functions and the advantages and disadvantages associated therewith relate in large measure to the anatomical peculiarities of each individual rupture. In general terms, the primary purpose of the-truss is to apply a pad or pads having appropriate contours with inward and upward pressure to the body, at points usually above the pubic line in the vicinity of the groins, the exact positions of the pads depending upon the nature and locations of the ruptures. The positions of the pad'contours relative to the body, as well as the directions in which the pressure is applied and the magnitudes thereof vary considerably in different cases. However, once adjusted for a particular case, the pads should ideally remain in constant relationship to the body, Without rocking or slippage with respect to the ruptures.

During periods of inactivity, as at night, a truss consisting of a flexible belt without rigid reinforcements, encircling the body and holding the pad or pads in place, is ordinarily satisfactory. However, considerable difliculty is encountered with this type of truss during activity, both in respect to keeping the pad or pads in their proper locations and in maintaining the requisit pressures of application.

The conventional solutions to the problems arising from the activity of the truss wearer are embodied in two principal types of trusses. In the first type, a leg strap is added to the elastic belt, the strap passing between the legs and being attached to the truss at the front and back to hold the belt down and in some cases to tilt the pad outwardly at the top to produce a slightly upward thrust upon the ruptured area, as is usually required. However, such construction is not suited to cases where strong support 'is needed; nor does it provide suflicient flexibility of pad adjustment. Furthermore, the leg strap gives rise to additional discomfort.

reinforcing springs of the truss are relatively strong both in bending and torsional flexure. They are prebent over a radius of curvature smaller than that of the body, the object being to hold the support proper in place by a pinching or vise-like action between the abdominal pads and back pads. The back exerts pressure upon the ends of the springs through the back pads, and this pressure is transmitted through the springs to the abdominal pads. Normally, the springs are held slightly away from the body at the sides to prevent interference with this bending or vise-like action and to permit movement of the hips independently inside the springs. In many cases, .this

clearance is great enough to permit a finger to be inserted freely between the belt and body at any place around the hips.

By reason of the above-described action of the rigid truss, it is necessary for the springs to have considerable strength in bending fiexure, that is, flexure in the plane of encirclement of the body, so that the truss will hold the abdominal pads in place when theposition of the body is changed. Also, it is highly desirable that the pressure upon the rupture should not vary too much in the normal range through which the springs are fiexed. To satisfy these requirements, each spring is preferably extended from the abdominal yoke, to which it is rigidly afiixed, to a pad placed close to the spinal column, and is sufiiciently strong to give the required pad pressure for the given length of spring. The result is a structure which possesses considerable rigidity except in the plane of bending. It is too stilf to conform with the body contours during movement and must be suspended clear of the body to permit movement thereof inside the springs. This is particularly disadvantageous for persons in climbing occupations, such as plumbers, since to lean or lie against the side is to force the spring on that side against the body, and to cause slippage or dislodging of the abdominal pads and ensuing aggravation and pain. Also, by reason of the rigidity, the hernia tends to slip away from the padunless the truss is drawn so tightly around the body that the springs cut into the body at some points while large gaps occur in other places.

in addition to the above, the nature of the construction of a rigid truss requires considerable time and skill on I the part of the fitter in making needed adjustments. Special fixtures and fittings for the truss or the pads for attaching and adjusting the pads to the truss proper are required, which are often cumbersome and unsightly and tend to catch and wear the clothing and to require frequent readjustments.

It will also be noted that a characteristic of the rigid truss is that it is suspended upon the'body at four principal points, two of which are closely adjacent to the The other conventional type is the so-called rigid truss.

In one characteristic form, this truss is constructed, with a rigid abdominal yoke having one or two attached abdominal pads, the yoke being extended Well beyond the pads on either side and permanently affixed to side springs inserted in a belt encircling the body. Alternatively, the yoke and side springs may be formed of a single piece of wire having a flattened cross-section and of an appropriate strength and flexibility to serve an equivalent function. a The side springs encircle the body, and eachspi'ing is terminated at aback pad in the belt resting against the body closely adjacent to the spinal column. this truss, it is convenient to consider the unit consisting of the abdominal yoke and the attached pad or pads as a In discussing single entity, which may be referred to for convenience as the support proper.

certain inherent disadvantages which may. be seen by reference to the underlying principle or mode of operation thereof, and the character of the support afiorded. The

.closely except'between the abdominal pads, and-to follow spinal column on either side thereof, and two of which are at the locations of the abdominal pads, the intermediate points around the body circumference being of no appreciable significance in locating the truss in relation thereto.

According to the present invention, an improved and radically different type of truss construction is employed. It has the disadvantages of neither of the above-described conventional trusses, and may be worn during activity without .a leg strapwhile continuing to provide great strength and comfort and to afford positive holding power and positive insurance against slippage or rolling of the abdominal pads.

An important object of the invention is to provide a truss' having holding strength commensurate with that of the familiar rigid trusses. p Another important object is to provide a truss having the above feature, yet :being adapted to fit the body "the movements of the body to permit the wearer to lean Patented June 7, 1955v or lie on a side without changing the positions of the abdominal pads inrelation tothe body and to improve the general appearance of the truss.

Another object is to provide an improved truss in which rapid and proper fitting and adjustment of the pads is facilitated, and maintenance of the proper support thereafter is insured.

Another object'is to provide a truss in which the above objects areattained while yet permitting the truss proper to be correctly positioned with respect to the body at all times and in all normal positions thereof.

With a view to the above objects and others hereinafter appearing, an important feature of the present in vention is a semifiexible, split frame construction consisting of a short, rigid abdominalyoke to one or both of the ends of which the abdominal pads are adjustably secured, and a belt with reinforcing springs adjnstably secured to the yoke and pads, in which each of the parts is adapted to fit. a certain section of the body at all times, and in all normal positions thereof, so that the truss is snugly fitted'to the body at every point around the circumference, except between the abdominal pads. Theabdominal yoke is preferably no longer than necessary to secure the pads and is specifically designed to fit the groin area.

According to another feature, the belt is reinforced by a new type of body contour spring fastened directly to the pad, the spring having negligible strength in bending to reduce to a minimum the pinching or vise-like action employed in the rigid truss, and to permit conformity with bodily movements, but having suficient resistance to torsional bending to prevent rolling of the abdominal pads.

According'to another feature, a unique method of joining-the abdominal yoke and side springs permits great flexibility, ease and speed of adjustment and fitting to the needs of each case.

According to still another feature, the points of suspension of the truss; by means of back pads near the spinal column are completely eliminated. This introduces a radically different mode of positioning than that of the rigid type trusses. heretofore described; yet the degree of support aiforded is commensurate therewith.

According to the improved construction, the abdominal yoke, the reinforcing springs, and the abdominal pads are. secured together by a single control screw in a manner permitting great rigidity, yet affording adjustability not only'of the pads, but also of the eifective lengths of the springs and the abdominal yoke. This reduces fitting time, and permits rapid custom fitting and selection of'the component partseven though the sizes of the trusses are widely separated, as by eliminating all of.

theeven or oddsizes inmanufacture.

According to still another feature, the side springs. are fastened to theabdominal yoke directly over the pads, rather than at points closer to the hips. as is commonly done in the rigid type trusses.

The resulting truss is a combination of parts so designed that the truss becomes a full fashioned, contour fitting appliance that hugs the body evenly, distributing the pressure in such a manner that holding power is achieved through the trussand body working in unison, individual body characteristics notwithstanding.

Other features of the invention relate to certain features of construction and modes. of operation as hereinafter described and particularly defined in the claims.

Fig. 5 is an exploded view of a portion of the truss shown in Fig. l with belt removed to illustrate certain features of the construction; and

Fig. 6 is a pictorial view of a preferred form of the invention as embodied in a single truss for an inguinal hernia.

Referring to Fig. 1, the truss proper consists of a rigid metallic abdominal yoke 2, and a pair of abdominal pads d secured to its ends in a manner hereinafter more fully described. The yoke is shaped to have a substantially horizontal central portion and end portions extending obliquely upward from the central portion when fitted to the groin area of the wearer. A flexible belt 6 in two pieces is also secured to the ends of the yoke and passes round the body, fastening at the back in any suitable manner, as by a hook and slotted fixture in the respective pieces. The. belt is formed as hereinafter described to permit a reinforcing spring to be inserted in each side, the spring being adjustably and firmly secured at the front end of the. abdominal yoke and pad, and extending to a point behind one of the back covers 8.

The construction of the belt is described with reference to Figs. 2 and 3, in which the reinforcing spring has been removed. On the side facing the body, a piece of elasticized fabric or webbing 10 extends the entire length of the belt, being cut relatively narrow on the sides and fullwidth at the back. However, by reason of the.

other pieces of fabric to which it is secured, the only section of the belt in which the elastic can be stretched appreciably is in the portion intermediate of the back.

covers, or to the. right of the cover 8 as seen in Fig. 2. An outer piece of non-elastic fabric or webbing 12 is sewed to the piece 10 to form a space 14 for insertionof the reinforcing spring. The piece 12 extends fromv the forward end of the belt to and under the back cover 8. The front end of the piece is reinforced by a tearproof cover 16, preferably made of leather, which provides support for the edges of a hole 18 passing through.

the" belt. At the other end the pieces. 10 and 12 are covered by

leather pieces

20 and 22 forming the back.

cover 8, which strengthens the belt against the action of the end of the reinforcing spring and provides a smooth surface against'the body.

The top and bottom edges of the beltare preferably protected from unravelling or fraying and are prevented from cutting the skin by a binding 28 of leather or similar cushioning material extending from the front end to and beneath the back cover 8. Thebinding ispreferably thick enough to cause the belt to be raised slightly at the edges thereby preventing slipping or chafing of the skin, and creating an air pocket for ventilation. Means for securing the belt in theback, such as a metal hook 3.0. to engage with a corresponding slotted fixture in the other. end ofthe belt, are secured tothe elastic portion of the piece 10in any convenient manner, as by sewing it into a short'loopof fabric 32. The end of the piece 10 is protected by a. strip 34 made. of leatherv or other suitable material stitched thereto.

The reinforcing piece 16 is open at the left end as viewed'in Fig. 2 to permit insertion of the reinforcing spring which: preferably extends as far as the. stitching in the" back cover Swillpermit.

The shape of the reinforcing spring 36 may be seen.

by reference to Fig. 4, which is a. fragmentary view of the forward end of the spring. In the preferred embodiment as described, the. spring presents the plan.

localize pressure. directly above the pubic bone and..to.

prevent rocking'of the pad. Inv the oifset portion of the Another view of the spring 36 is provided in Fig. i

which is an exploded view showing the manner in which the abdominal yoke 2 is connected therewith. The yoke 2 is provided at its ends with horizontal slots 44, and serrations 46 on one surface to engage with the serrations 42 of the spring. End walls 48 are preferably formed in the yoke, with a separation equal to the width of the spring to prevent the spring from rotating with respect thereto.

The pad 4 is preferably constructed with a rigid frame, covered if desired with a suitable material, and having a single threaded hole 50. The assembly of the foregoing parts is accomplished simply by means of a single control screw 52 which passes through the abdominal yoke and reinforcing spring into the hole 50. When the screw is tightened the

serrations

42 and 46 clutch and secure the yoke and spring to prevent slipping and the end walls 48 prevent rotation of the spring with respect to the yoke. Also, gripping projections 54, preferably formed in the end walls of the yoke, engage with the pad 4 and prevent its rotation.

It will be apparent that by loosening the screw 52 it is possible to conveniently change the position of the pad 4 by rotation, or to move the position of the bend 38 with respect to the juncture of the abdominal yoke and pad, or to change the distance between the pads, as desired.

It will be appreciated that the drawings are merely illustrative in so far as scale is concerned, the exact dimensions of the parts, particularly as shown in Figs. 2 and 3, being determined by the usual criteria of strength, flexibility and wearing comfort.

In assembly, selected reinforcing springs of the required thickness and hardness are first inserted into the spaces 14 of each half of the belt so that the slots 40 coincide with the holes 18 in the belt. Next, the abdominal yoke 2 is inserted into the openings in the leather reinforcing pieces 16 and around the springs so that the slots 44 are also in alignment with the holes 18. The control screws 52 are then inserted through the holes 18 and the slots in the yoke and springs, and threaded into the holes 50 in the pads. The adjustments heretofore described are readily made by the fitter according to individual requirements, and the screws 52 are then tightened sutficiently to hold the parts firmly together.

When worn as shown in Fig.1, the belt forms a semiflexible structure, which fits all around the body except in the space between the pads. The springs are relatively weak in bending flexure, permittingthe conformity to be maintained notwithstanding the motions of the hips. Thus, the belt is flexible, but a considerable degree of resistance to torsional flexure is introduced by the springs, whereby the oflset of the pads with respect to the groin introduced by the bends 38 in the springs permits the pads to exert an appropriate thrust upon the herback, since all points between the pads and theback are' continuously in contact with the body and move in unison with it.

Another convenient means of adjustment of the truss available to the truss fitter takes the form of an inward indentation in the region designated 56 in Fig. 4, which is made by bending the side spring inthis region to caus the belt to fit snugly right up to the pad. I

The embodiment of Fig. 6 illustrates an application of the invention to the case of a single inguinal hernia. The construction is very similar to the above on the side of the truss incorporating the operative abdominal pad. However, in place of the rigid abdominal yoke 2 ,a relatively flexible and malleable metal yoke 58 of approximately the same length is used. The yoke 58 is preferably secured to the operative pad 60 and reinforcing spring (not shown) in the manner shown in Fig. 5 and heretofore described.

The other end of the yoke 58 is formed into a hook engageable with a fixture 64 of any suitable form which is secured to the other end of the belt. flexible in the entire portion 65 extending from the back cover 66 around' the body to the fixture 64,'and it extends on the opposite side forwardly past the screw 68 and across the abdomen in the form of anelongated cover or channel for the yoke 58. The belt is terminated in a dummy pad 70 integral therewith. The pad 70 protects the wearer from the exposed hook and the fixture 64, and oifers such nominal support to the groin as may be deemed necessary. Adjustment of the pad 70 can be made to fit any desired abdominal curvature.

The above design provides a means for fastening the belt around the body without resorting to a fastening that L hooks directly to the hernia pad, a method which has 1 the disadvantage of tending to pull the pad away from the rupture.

action of the yoke 58. The fulcrum of the lever is located approximately in the region of the bend 72 in the spring and the force on the end of the lever is exerted by the elastic portion 65 of the belt. Adjustments of the pad position,as well as of the eifect-ive length of the piece 58 and the reinforcing spring may be made in the same manner as described with reference to Figs. 1 to 5.

It will be apparent from the mode of operation that the described trusses may be modified by decreasing the lengths of the side springs so that they extend just over the hips, or only a suflicient distance to ensure the required torsional strength to prevent rocking and slippage of thepads;

It will be understood that theinvention has been described with reference to its preferred embodiments as adapted for inguinal ruptures, and that various modifications indetails of construction, consistent with the principles of the invention may be irnade in accordance with the principles presently understood in the art, to

suit the needs of any particular application, and without departing from the spirit or scope of the invention.
