The invention relates to orthopedic tables.
One object of the invention is to provide an improved table which is adapted to hold the patient while X-ray photographs are being taken and which is adapted to serve also to hold the patient for other work, such as the setting of fractures, without removing the patient from the table, thus avoiding the necessitay of removing or disturbing the patient.
Another object of the invention is to provide an improved table top which is provided atone end with a mast and adjustable straps for supporting the'body and in which the table-top is slidable back and forth so that the body of the patient will be free for the application of a body jacket and so that the table top may be slipped back under a patient after the jacket has been applied to make it unnecessary to lift the patient. Another object of the invention is to provide an improved table which has a top frame that may be swung into vertical position so the jury mast may be used to obtain vertical extension in the application of a body jacket or cast.
Another object of the invention is to provide an improved table which has a movable top, extensible supports for holding and extending the feet and in which the jury mast is utilized in supporting the hips.
Other objects of the invention will appear from the detailed description.
The invention consists in the several novel features hereinafter set forth and more particularly defined by claims at the conclusion hereof. l
In the drawings: Fig. 1 vis a longitudinal section of a table embodying the invention. Fig. 2 is a side elevation, showing the table in position for use in the application of body jackets or casts. Fig. 8 is a side elevation, showing the part in position for holding and extending the feet with the hip supported on the jury mast. Fig. 4L is a perspective of the table top. Fig. 5 is a perspective of the swinging table-frame.
The-invention is exemplified in a supporting structure comprising a pair of A-frames 10, which are spaced apart and iixedly secured together in spaced relation by cross- 1925. Serial No. 28,761.
rods or tubes 11'. The legs of these frames are provided with casters 12, so that the structure may be wheeled about and serve as a cart, as well as a table. A pair of supplemental legs 18, fixed to a cross-bar 14, which extends between, and is pivoted in, the frames 10, are provided with rubber feet 15 When the legs 13 are swung into the position indicated by dotted lines in Fig. l, and against the adja cent cross tube 11, the structure will be stationarily held on the floor, which is desirable when the table is in use.
A rectangular top frame, preferably made of pipe and pipe fittings, comprises side members 16 and end members 17 and 18. r1`hese 'members are rigidly connected by elbows 19 between end 17 and side members 16, and T-iittings 2O between end member 18 and the side members. Said side members eX- tend through sleeves 2l respectively, which are provided with pivots held in fittings 22 at the upper ends'of the A-frames, respectively. Set nuts 23 are threaded to and eX- tend through sleeves 21, to secure the top frame against longitudinal movement in the supporting structure, when desired. A pair of braces 24 have their lower ends pivoted, at 25, to the A-frames respectively, and each is provided at its upper end with a pair oi holes 26, `27. Set screws 28 are adapted to pass through the holes 26 to secure the braces to the frame sides 16. A pair of braces 29, having their lower ends pivoted to the A- frames at 30, have their upper ends pivoted, at 31, to sleeve brackets 32, which are slidable on the frame-side 16 and are adapted to be secured thereon by set-screws 33, which are threaded to the brackets 32, and are adapted to clamp said sides and sleeves together. These braces are adapted to secure the pivoted top-frame against vertical movement in the supporting structure. When the top frame is to be secured in vertical position, for example, when it is desired to obtain vertical extension in the application of a body jacket or cast', the set screws 23 are released to permit the frame sides 16 to slide in sleeves 21, so the frame may be swung into vertical position, indicated by dotted lines in Fig. 1. When the top frame has been so shifted, it may be secured in its desired position against vertical movement, and against longitudinal movement, by tightening the screws 23, and against pivotal movement by tightening screws 33, so the braces 29 will be effective to hold the frame.
A table-top 35, which is preferably formed of aluminum, is adapted to overlie and be suported by the adjustable top frame, so that 1 -ray photographs may be taken through the top and luoroscopic work done while the patient islying on the top. The top is completely removable from the top frame, being provided with handles 36, for convenience in moving it. .It is also slidable longitudinally on the top frame, so that portions of the body of the patient may be supported, while other portions remain unsupported by the top, to provide complete access to the unsupported portions. The removable table top fits between the upper ends of braces 24 and between brackets 32, to prevent its transverse displacement from the top frame. When the table top 25 is positioned over the top frame, one end thereof projects beyond and overhangs one end of the top frame. The overlying end of the table top may be held down on the top frame by a cross-bar 37, which extends over the table top and is removably held in slots 38 in the brackets 32.
A cross fitting 40 is mounted on the end member 18 of the top frame, and this fitting is adapted to support a jury mast 41, which is removably secured in the fitting by a screwthread, which permits the removal of the mast when its use is not desired. A set screw 42 is adapted to secure the fitting 40 in desired position on member 18. A supporting strap 43 of any suitable character, and for supporting the head or other portion of the body, has its ends connected to stirrups 44, is adjustably supported from the mast 41 by means of pulley blocks 45, 46 and a cable 47. The upper f pulley block 46 is pivotally secured to the upper end of the mast by a ring 43 and the stirrups 44 are connected to the pulley block 45 by means of an eye 49, through which the bar, forming the stirrups, extends.
ln some operations, it is desirable to hold and extend the feet of the patients, and for this purpose a rod 50 is adapted to slide in either of the side members 16 of the top frame, and an arm 51 is ixed to the outer end of said rod. A set screw 52, in fitting 20, is adapted to secure the rod against longitudinal and rotative movement, when the arm has been adjusted into its desired position. VIf desired, a leg support of this character may be inserted in each of the side members 16.
lhen the table top 35 is in position shown in Fig. 1, and a patient has been placed thereon, X-ray photographs may be taken of any part of the patient and fluoroscopic work done, without in any way disturbing the patient, because the X-ray easily passes through the aluminum. This is of especial advantage in fracture cases, because the setting of fractures can be done directly following the taking of the photograph, without removing the patient from the table. Vhen it is desired to apply a body jacket, the table top is shifted longitudinally over the top frame, so as to leave suflicient clearance between one end of the table and the jury mast for access to the body of the patient, as shown in Fig. 2. With the table top in this position, the lower limbs of the patient are supported on the table top and the head is supported by the strap 43, which may be drawn into correct position by adjusting the strap by means of the cable and ulley blocks supported from the mast 41. Vhen the patient is supported, as indicated in Fig. 2, a body jacket or cast may be readily applied to the patient, because all portions thereof are then accessible for that purpose. VvThen the table top is in this position, the cross bar 37, 'which extends across the top of the table, will be locked in slots 38 to hold the table top on the top frame. When it is desired to perform work on the lower limbs of the patient, or to hold and extend the feet, the rod 50, which carries the arm 51, will be adjustable longitudinally and rotatively to bring the arm into desired position, and the foot of the patient will be bandaged or strapped thereto. By tightening the set screw 52, the arm may be iiXed in its assigned position. If, while performing work on the lower limbs of the patient, it is desirable to provide greater clearance between said limbs and the top frame, and clearance between the foot support and the table top, set screws 28 will be extended through the openings 27 and into the table top, and the braces swung into position indicated kin Fig. 3, so that the remote end of the table top will rest upon the top frame and the other end will be supported by the braces 24, as indicated in Fig. 3. In this position, the table top will be adapted to support the body of the patient, the foot will be supported 0r extended by the supporting arm 51, and the lower limbs will be completely accessiblefor operative work, if desired. If, while the table is thus used, it is desired to support the hip of the patient, a suitable support 53 may be slid upon the jury mast and used for this purpose, as shown in Fig. 3.
When it is desired to produce vertical eX- tension of the body for the application of a body jacket or cast, the table top is removed and braces 24 are disconnected at screws 28 from the top frame. When the set screws 23 are released, the top frame will be slidable in and pivotally movable with sleeve pivots 21, to bring it into the vertical position indicated by dotted lines in Fig. 1. It may be locked in such position by tightening the set screws 33, so that the braces 29 will be effective to secure the top frame against pivotal movement in its vertical position, and the set screws 23 are tightened to secure said frame against sliding movement in said pivoted sleeves. When the top frame is in vertical position, the ury mast will project therefrom, so that a head strap may be connected to the stirrups 44 and the pulley blocks 45, 46 and cable 47. By manipulation of the cable 47, the strap may be adjusted to eiect the vertical extension desired. In this position, the body will also be free for the convenient application of a body jacket or cast.
The invention exempliies an improved orthopedic table, with a top which is placeable on and removable from the top frame, so that X-ray photographs may be taken through the top and luoroscopic work done while the patient is on the top, so that when desirable, orthopedic work may be done directly following the taking of the photographs, without moving the patient; also one in which the table top is slidable, so the table may be conveniently used to support a patient for the convenient application of body jackets and casts; also one in which the top frame can be swung into vertical position to procure vertical extension of the body in the application of a body jacket or cast; and also one in which the tabletop is adjustable, and in which there is provided a foot support, so that the patient may be properly supported for orthopedic work on the lower limbs; also one in which the table top, which is adapted to X-ray work, is wheeled so that it may serve as a. cart for transporting the patient from place to place.
The invention is not to be understood as restricted to the details set forth, since these may be modified within the scope of the appended claims, without departing from the spirit and scope of the invention.
Having thus described, the invention, what I claim as new and desire to secure by Letters Patent, is:
l. In a table of the character described, the combination of a supporting structure, a rectangular top frame comprising side and end members and pivotally connected to the structure so it may be swung from horizontal to vertical position, a slidable connection between the structure and the side members of the fra-me for permitting the latter to be shifted longitudinally, and a mast mounted on one of the end members of the frame and provided with adjustable means for suspending a human body.
2. In a. table of the character described,
the combination of a supporting structure, a. top frame pivotally connected to the structure, so it may be swung from horizontal to vertical position, means for securing the frame, a holder-supporting mast on one end of said top frame, a top slidable over said frame to and from the mast, and means for holding the top when it is extended to project over the other end of the frame.
