This invention appertains to surgical appliances and more particularly to means for handling leg fractures between the hip and ankle in children permitting and allowing free excursions from head to foot of the bed.

One of'the primary objects of my invention is the provision of a device for association with a standard size childrens hospital bed having means by which the fractured 1o limb or limbs can be suspended from an overhead support in such a manner as to leave the body of the patient free for movement.

Another important object of my invention is to provide a surgical apparatus for handling ieg fractures, which can be readily'and easily attached to a hospitalbed and adjusted to the size of the patient and the particular requirements of the fracture.

A further object of my invention is the provision of a wheeled frame movable to operative position relative to a hospital bed having a longitudinally movable carrier disposed over the bed, the carrier embodying a freely movable circular track from which depends suitable foot harness for engaging the fractured limb or limbs, means being provided for creating a tension or pull on said foot harness.

A further object of my invention has the provision of means for locking the circular track in an adjusted position when necessary or desirable.

A further object of my invention is the provision of novel means for clamping the apparatus to the bed whereby the apparatus will form a rigid part of said bed when in use.

A still further object of my invention is to provide and improve surgical apparatus of the abovecharacter which will be durable and eflicient in use. One that will be simple and easy to manufacture and one which can be placed upon the market at a reasonable cost.

claimed and illustrated in the accompanying drawings, in which drawings:

With these and other objects in view the Figure 1 is a side elevation of my improved device showing the same applied to a hospital bed and in use.

,Figure 2 is a top plan view of the same, and

Figure 3 a vertical section taken on the line of 3 3 of Figure 2looking in the direction of they arrows, the bed being omitted in this view.

Referring to the drawings in detail, wherein similar reference characters designate corresponding parts throughout several views the letter A generally indicates my improved surgical apparatus and B a hospital bed with which the same can be associated.

The bed B can be of standard construction and includes the usual head and foot pieces 5 and 6 supporting the conventional bed spring and mattress. As shown, the legs of the bed are provided with castersor rollers 7.

My improved apparatus embodies a supporting frame work preferably formed from tubular material bent into the desired shape. This frame includes oppositely disposed end sections 10 and 11 each of whichconsists of vertical upright spaced parallel posts 12 connected at their lower ends to a cross-piece 13. The terminals of a cross-piece 13 may carry depending legs 14 supporting rollers or casters 15 preferably provided with rubber or fibre treads. The cross-pieces 13 of each end section 10 and 11 can be connectedtogether by longitudinally extending rail 16. The upper terminals of the posts 12 of the sections 10 and 11 are connected together by longitudinally extending spaced parallel connecting bars 17 which form tracks, for a purpose which willlater appear.

The spaced parallel bars 17 are hollow and the lower faces are provided with longitudinally extending slots forming guideways. The walls of the slots are extended inwardly to provide guide flanges 18 on which travel pairs of anti-friction rollers 19. These rollers 19 are preferably formed of fibre so as to reduce noises incident to their travel in said bars 17. The rollers 19 carry depending studs 20, the lower ends of which are rigidly connectedto an uppercircular track 21. By this construction it can be seen that the circular track 21 canbe freely moved longitudinally of the apparatus. Disposed below and concentric with the upper circular track 21 is a lower circular track 22, which lower track 22 carries upstanding rigid studs 23. These studs 23 rotatably carry anti-friction rollers 24 mounted for movement in the up per circular track 21. By this arrangement, the lower track 22 is freely movable relative to the upper track.

The lower track 22carries the means for engaging and supporting the leg or legs of the patient and this means embodies suitable tension cables or the like 24. The inner ends of the cables 24 carry any preferred type of harness 25 for engaging and holding the feet of the patient while the outer ends of the cables support suitable weights 26. The tension cables 24 adjacent to their outer ends are trained over guide pulley wheels 27 carried by the lower ends of an inverted U-shaped frame bar 28. This frame bar 28 is secured to and extends transversally of the upper parallel bars or tracks 17. The forward ends ofthe cables 24 are trained over guide pulleys 29, which pulleys are carried by depending studs 30. The upper ends-of the studs 30'carry rotatable anti-friction rollers 31 mounted for movement in the lower circular track 22. By this arrangement, it is obvious that the pulley wheels 29 are freely movable around the lower track 22.

In use of my improved surgicalapparatus, the same is wheeled towards the bed B with which the same is to be used and one edge of the bed can be lifted over the longitudinal rails 16 of my device. lviy apparatus is then firmly clamped to the bed and I provide novel clamps for this purpose. The clamps are movable, within certain limits, on the uprights 12 so that the same can engage di'lferent sizes of head and foot pieces of beds as shown. Each of the clamps include a horizontal bar 32 the terminals of which carrry pins 33 slidably received in suitable slots 34 formed in the uprights 12 of end pieces 10 and 11 of the frame. Slidably -mounted through the-center of each horizontal bar 32 is the threaded shank 35 of a hook 36. The shanks 35 have threaded thereon wing nuts 37 which are adapted to infringe against the outer faces of the horizontal bars 32.

In use of the clamps, the nuts 37 are loosened and the horizontal bars, 32 are moved to the desired elevated position and the hooks 36 are placed over the top rails of the head and foot pieces 5 and 6 of the bed B. The wing nuts 37 are now tightened which will force the hooks 36 into intimate gripping contact with the head and foot pieces of the bed and the pins 33 into binding engagement with the inner walls of the slots 34 of the uprights 12. This will lock the horizontal bars 32 in their adjusted position and the hooks 36 into contact with the bed holding my ap paratus positively locked with the bed.

The fractured limbs of the child are now raised as shown in Figure 1 of the drawings and the foot harness 25 attached to the patient. The weights 26 will create a tension on the fractured limbs and hold the same in the desired elevated position and the formation of the device will allow free movement of the body of the child.

'When it is desired to lock the lower track 22 against movement and the pulley wheels 29 against travelling about in the low-er track, these elements can be firmly held in place. As shown certain of the studs 23 have threaded thereon adjusting nuts 38 which canbe threaded into binding contact with the lower face of the upper track 21, which will prevent rotation of the lower track. Likewise the studs 30' of the pulleys 29 can have threaded thereon nuts 39 which can be moved into engagement with the lower face of the lower track 32 so as to prevent travel of the pulleys around said track.

Likewise the circular tracks can be held in any adjusted position longitudinally of bars 17 by suitably locking mechanism, which embodies a spring pressed locking bolt 40 slidably carried by frame structure 41 secured to the upper face of the track 21. This latch bolt 40 is normally urged toward a longitudinally extending locking bar 42 arranged between the parallel bars 17 The locking bar 42 is held in place by suitably transversally extending straps 43 connected with the upper faces of the parallel bars 17. The locking bar 42 is provided with spaced keeper openings 44 into any one of which the latch bolt 40 is adapted to spring.

A depending pull chain 45 is connected with the lower end of the latch bolt so that the same can be pulled downwardly from out of engagement with the lock bar 42 so that the circular tracks can be moved to the desired positions.

From the foregoing description it can be seen that I have provided an exceptionally simple apparatus for efliciently handling the fractured limbs of children and which will facilitate the rapid knitting of the fractured limbs.
