Operating Table

Abstract

An operating table for lower portions of the human body comprises a single bar that extends lengthwise from the table and carries supports for the legs and feet on either side of the bar. The supports are adjustable, those for the feet being universally mounted at the ends of a pair of arms that extend swingably from both sides of the bar on a holder that is movable lengthwise of the bar. The bar itself is movable transversely of its length, from side-to-side of the table, by means of a crank-operated slide.

Description

In skeleton surgery which relates to the lower extremities and hip region, respectively, there exist special operation tables or particular arrangements adapted to be connected to a normal operation table. The equipment for this kind of surgery is constructed with the view of obtaining possibilities so to place the extremities that incisions easily can be made on the right as well as on the left side and, respectively, that by suitable auxiliary means the extremities at resetting can be stretched and rotated for effecting the best fitting of, for example, a broken leg.

In earlier constructions one has used two bars or booms for supporting both legs of the patient. In connection with the introduction of radioscopy with the help of image amplifier and television circuitry a great number of problems have arisen. The irradiation usually must be carried out in two planes and, irrespective of whether a pivotal arrangement mounted on a bow is used or a double equipment of image amplifiers with associated X-ray tubes, the space around the patient is very limited. For at all rendering it possible to utilize image amplifiers, the X-ray equipment and operation table must specially be adjusted to each other. Hereby the equipment becomes less flexible--different types and makes of X-ray equipment require table variants of their own.

The present invention relates to a construction, in which the field around that side of the patient which is subject to incision to a large extent can be left free from structure, which facilitates the surgeon's work and, in addition, provides space for the mounting of X-ray equipment of different types and makes. This has been achieved by using only one bar or boom, which in principle is placed on that side where the patient has his sound leg. The change of side is made by placing the bar, for example by being mounted on a slide, on the desired side before the patient is laid on the table.

For elucidating the invention, it is referred to the accompanying drawing showing an embodiment of the operation table.

FIG. 1 is a plan view of the table.

FIG. 2 is a corresponding side view.

FIG. 3 is a plan view of a detail.

The tabletop 1 with the extension plate 2 for supporting the patient can be constructed for use together with a rigidly mounted (hydraulic) foot 3 known per se, which includes the details required for operating the tabletop--lifting and lowering, high and low position of the head. Between the fittings 4 required for mounting on foot 3 there is a slide 5, on which a bar 6 is mounted by means of an angular piece 7. The slide 5 can be moved from the left to the right side, and vice versa, by means of a screw 8 which is operated with the help of a handle 9 . On the bar 6 which suitably has noncircular, for example rectangular cross section, necessary equipment of different types can be mounted. In the drawing are shown two foot supports which are universally adjustably mounted at the free ends of arms 10 and 11, the other ends of which are pivoted on a holder 17 adapted to be moved on the bar and to be locked in set position. There are further shown leg supports 12 and 13 for the two extremities supported on holders 18 and 19 adapted to be moved and locked on the bar 6.

In the position shown, the surgical incision, for example nailing of a fracture, is assumed to be performed on the right-hand side of the patient. As seen, the area both below and on the side of the patient is free for mounting different types of X-ray equipment.

The extension plate 2, after the removal of a mattress 20 fastened thereon, can be pulled in below the tabletop 1 by a handle 14 in order to render it possible, for example, to put the hip in plaster of paris. For supporting the patient during such a procedure, a special holder 15 with a bottom plate 16 (FIG. 3) can be mounted on the bar 6. Instead of the slide 5 other constructions can be imagined, which render it possible to place the bar on the right-hand or left-hand side, for example a hinged a arm system with screw connections.

Claims

I claim:

1. An operating table comprising a support for the body of a patient, a bar extending lengthwise from the table, means carried by the bar on opposite sides of the bar for supporting both legs of the patient, and means for adjustably moving the bar transversely of the length of the bar from side to side of the table.

2. An operating table as claimed in claim 1, said moving means comprising a slideway extending transversely of the table, a slide carrying said bar, and screw means for moving said slide on said slideway from side to side of the table.

3. An operating table as claimed in claim 1, said supporting means comprising a pair of foot supports disposed one on either side of the table, a holder slidable along said bar, a pair of arms pivotally mounted on said holder on opposite sides of said bar, and means mounting said foot supports one on each of said arms for universal adjustable movement relative to said arms.

4. An operating table as claimed in claim 1, said supporting means comprising a pair of leg supports mounted on said bar and extending to opposite sides of said bar, said leg supports being separately adjustable along the length of said bar.
