COMPLETE SPECIFICATION.
An Improved Surgical Operating Table.
We, OTTO IHLE, of 48¹ Pragerstrasse, Dresden, in the German Empire, Doctor of
Medicine, and FRIEDRICH HERMANN MÜLLER, of 33 Reitbalmstrasse, Dresden
aforesaid, Locksmith, do hereby declare the nature of our said invention and in
what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
The object of our invention is to construct an improved surgical operating table, so
arranged that the mattress or its equivalent is capable of being adjusted to any required
position without disturbing the patient or body.
And in order that our said invention may be particularly described and ascertained,
reference is hereby made to the accompanying drawings, in which similar letters of
reference indicate corresponding parts.
Fig. 1 is a perspective elevation of the table, the mattress being removed to show
the working parts more clearly.
Fig. 2 is a similar view showing the mattress in position.
Fig. 3 illustrates the table arranged at an angle of 45 degrees.
Fig. 4 illustrates the table inclined in an opposite direction to that shown
in Fig. 3.
.
Fig. 5 illustrates the supports for the legs of the patient.
Fig. 6 is an illustration of the back support and head rest.
The invention consists of a rectangular frame R, to which the mattress or bed T
is fitted. u is another rectangular frame, carrying a bearing D at each end, in which
the journals of the screwed spindle Crevolve. The projecting ends c¹ of the spindle C
are made square to facilitate its being turned by the handle and key M. E is a
travelling nut integral with the cross-head E'.
which
The outer ends of the cross-head E' are fitted with anti-friction rollers R',
run upon the side bars of the frame u. H, H, are two bars pivoted to the
cross-head E at their lower ends, and to the frame R at their upper ends. A is a
screw-threaded spindle, fitted with a travelling nut B and cross-head B'. One end of
the spindle A revolves in a bearing a attached to a cross-bar forming part of the
frame R, the other end of the spindle revolving in a bearing a¹, its outer end at a
being made square for the key M, whereby it is turned. b b are two guide rods
attached, at their inner ends, to the cross-head B¹. The rods bb are supported in
bearings attached to the upper frame R. The outer ends of the rods b b are
fitted to support bandages or straps G, and splints, knee rests, or pads S, and are also
fitted with spherical sockets K and screws æ for adjusting the position of the
rods supporting the pads, the screw A being used to regulate their position
longitudinally.
The knee rests S exert no pressure whatever upon the body, in consequence of the
method of fixing the bands or straps G, the latter being placed round the knee rests
or splints, and afterwards passed through one or more slot or slots near the edges of
the knee rests S, to securely hold the thigh or leg of the patient.
By regulating the position of the cross-head E' upon the screw-threaded spindle C,
by means of the crank-handled key M, the angle of the frame R and mattress T can
be adjusted as required, two illustrations of such adjustment being shown in
Figs.
and 4.
Leg supports L are shown by dotted lines in Fig. 2, attached to the upper frame R.
.מ

page_text: When the operating table is utilised in lithotomical operations, only one of the leg
supports L is required. In place of the pads S, with their supports, the wooden
board g', shown in Fig. 5, may be attached to the frame R.
The movable back support and adjustable head rest shown in Fig. 6 may be added
to the upper frame R. The horizontal frame c is fitted with cross-bars d carrying
a serrated rack or ratchet e³. The board a³ is pivoted to as shown, its angle
being regulated by the pawl 3 and ratchet e³. 93 is a clamp in which the bar k
is adjustably held. The head. rest 3 is attached to the rod by a hinge 13 and
thumb screw 1. Bolts y³ are fitted for securing the two boards a³ and c³ together,
when so placed.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
:-
1. The improved surgical operating table, substantially as herein before described
and illustrated by the drawings.
2. In an operating table as aforesaid, the combination of a frame R, bearing the
mattress or bed pivoted to two rods or bars H, the latter being pivoted to the
cross-head E¹, integral with the travelling nut E screw-threaded to screw spindle C
situated in the under frame U and and actuated by a crank M, severally operating
substantially as and for the purposes herein before described, and illustrated by
the drawings.
3. In an operating table as aforesaid, the combination therewith for the purpose of
adjusting the knee rest or splints S, of a revolving spindle A mounted in the frame R,
guide rods 6 mounted knee rests, or splints S, nut B and cross head B¹ travelling on
the screw threaded spindle A, severally operating in such a manner, as to enable the
vertical rods carrying the knee rests or splints to be so moved (by means of thumb
screw K.) that one can be raised higher or lower than the other, substantially as herein
before described and illustrated by the drawings.
4. In an operating table as aforesaid the combination of a back support or rest a³
pivoted to the board or frame c³ for attachment to the longitudinal sides of the frame A,
and adjustable by means of a ratchet e and pawl f³ carrying a head rest with a
jointed rod, substantially as herein before described and illustrated by Fig. 6 of the
drawings.
5. In an operating table as aforesaid the method of and means and appliances for
manipulating the knee rest or splints, whereby the same impart no pressure to the
limb, also the fastening of the bandages G to the rests or splints in such a manner,
that the bandage is placed round the rest or splint, and held in one or more slot or
slots in the frame of the splint or rest, substantially as herein before described and
illustrated by the drawings.

6. In an operating table as aforesaid the combination therewith of a plate or support
serving for lengthening the frame R and attached in such a manner, that the same is
securely held in the clips K, for securing the knee rest or splints, substantially as
herein before described and illustrated by Fig. 5 of the drawings.
