SURGICAL PATIENT SUPPORT
Abstract
A surgical table is pivoted to one end of a horizontal arm, the
other end of the arm being pivoted adjacent the top of a pedestal
so that the table can be supported outwardly from the pedestal in
cantilevered fashion and moved to various adjusted positions about
the pedestal. The pedestal is tethered by a elongated radial arm to
some point on the floor of the operating room or on the floor of an
adjacent anesthesia room so that the pedestal can be moved along
the operating room floor in an arcuate path, the radius of which is
the radial arm. The arm encloses cords and hoses for conducting
various utility supplies, such as air, electricity, patient
monitoring lines, vacuum and gaseous anesthetic through the arm to
outlets on the pedestal.

Description
BACKGROUND OF THE INVENTION
The present invention relates to a surgical table and more
particularly to a surgical table which is mobile, supported
outwardly from a pedestal in cantilevered fashion and which has the
pedestal of the table provided with outlets for various utility
services and sensing or monitoring lines.
The standard surgical table is usually built on a central pedestal
which may or may not be provided with wheels or casters This
central pedestal usually contains a hydralic lift mechanism for
raising and lowering the table. Because of the central pedestal, it
is not possible to take x-rays through the patient at the center of
the table. Consequently, certain surgical procedures must be
interrupted and the patient moved should the surgeon require x-rays
in this area. The central pedestal also prevents a surgeon from
seating himself comfortably at the sides of the table, at the head
of the table, or at the perineal end.
Also in the prior art, any utility service such as electricity
vacuum, compressed air, or gaseous anesthetic is usually brought to
the surgical table through various cords and tubing stretched
across the floor to wall sockets and hose outlets. All these cords
and tubing running across the floor present a hazard to surgeons
and nurses moving around the operating table. Accidental movement
of patient monitoring lines also creates a hazard to the patient or
the surgical table.
These various drawbacks of the prior art have been overcome in the
present invention which first of all provides a surgical table
which is mounted in cantilevered fashion to a pedestal. This leaves
the entire area beneath the table free for access to x-ray
apparatus and the surgeon. The cantilevered support arm is pivoted
to both the pedestal and the surgical table so that movement of the
table to various adjusted positions about the pedestal is readily
accomplished.
Other drawbacks of the prior art are overcome by delivering the
necessary utility services to the pedestal through a long radial
arm which extends from the pedestal and along the floor of the
operating room to an anchor or pivot point adjacent the operating
room wall. With this arrangement, the utility services can be wired
or piped from the anchor point and then through the radial arm to
the pedestal. Mounting the pedestal on wheels permits swinging the
entire pedestal and surgical table combination in an arc to various
parts of the operating room as required for various set-up
procedures.
SUMMARY OF THE INVENTION
Present invention may be characterized in one aspect thereof by a
pedestal adapted for movement along a floor surface; a radial arm
extending along the floor of the operating room, the arm having one
end fixed at a pivot and the other end connected adjacent the
bottom of the pedestal wherein the pedestal is movable in an
arcuate path, the radius of which is the radial arm; a surgical
table mounted to the top of the pedestal by a cantilevered arm so
that the table is supported outwardly from and adjustable about the
pedestal; and means extending through the radial arm to outlets on
the pedestal for conducting utility service supplies and patient
monitoring devices to the pedestal.
OBJECTS OF THE INVENTION
One object of the present invention is to provide a cantilevered
supported surgical table.
Another object of the present invention is to provide a surgical
table as aforesaid wherein the cantilevered support is pivoted to
both the table and to an upright pedestal to permit movement of the
table about the pedestal to various adjusted positions.
A further object of the present invention is to provide a surgical
table which has its pedestal tethered to a radial arm running along
the floor of the operating room so that the pedestal can be moved
in a arcuate path, the radius of which is the arm.
A yet other object of the present invention is to provide a
surgical table as aforesaid wherein utility service is delivered to
the pedestal through the radial arm.
These and other objects, advantages and characterizing features of
the present invention will become more apparent upon consideration
of the following detail description thereof taken together with the
accompanying drawings.
DESCRIPTION OF THE DRAWINGS
FIG. 1 is a perspective view showing the surgical table, pedestal
and radial arm of the present invention;
FIG. 2 is an elevation view showing use of x-ray equipment with the
table of the present invention;
FIG. 3 illustrates the range of movement of the pedestal to various
adjusted positions about the table; and
FIG. 4 is a plan view showing the range of movement of the
table.
DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring to the drawings, FIG. 1 shows the apparatus of the
present invention, generally indicated at 10, to include a table
portion 12. The table is carried on one end 16 of a cantilevered
arm 14. Arm end 16 is journaled to the bottom of the table adjacent
one edge 18 and the other end 20 of the arm is journaled to the top
of a pedestal 22. Pedestal 22 contains the hydralic lift mechanism
(not shown) for raising and lowering table 12.
Forming part of pedestal 22 is a service console 24. The console
and pedestal are mounted on wheels or casters 26 for movement
across the floor of the operating room in a manner set out herein
below.
Console 24 carries a plurality of outlets 28 which are connected to
various services such as monitoring lines, vacuum, anesthesia gases
and utility services, such as electricity and compressed air
through cords and tubing 30.
The cords and tubings 30 are enclosed in an elongated radial arm 32
which has one end 34 connected to service console 24 and its other
end 36 journaled at an anchor point where the services enter the
operating room. With this arrangement the entire apparatus 10 can
be moved in an arcuate path, the radius of which is the length of
arm 32. If desired, a drive motor and drive wheel 38, 40
respectively can be provided for driving the arm and therefore the
pedestal and surgical table through this arcuate path of
travel.
Referring to FIG. 2, the advantages of having surgical table 12
mounted in cantilever fashion outwardly from pedestal 22 becomes
readily apparent. As shown in FIG. 2, a mobile x-ray apparatus 42
may be brought into the operating room for taking x-rays of the
patient on the surgical table. Since there is no support column
directly beneath the central portion of the surgical table, x-rays
of the patient may be taken at any point along the patient's body.
Likewise, a surgeon can comfortably seat himself at the side of the
table with his legs extending beneath the table.
One advantage of having the surgical table adjustable with respect
to pedestal 22 is shown in FIG. 3. Since cantilevered support arm
14 is journaled at one end to the table and at its other end to
pedestal 22, the pedestal can be easily moved about the table from
the position shown in solid line in FIG. 3 to positions A and B
shown in dotted line. In the position shown in solid line, service
console 24 which is part of the pedestal is positioned to
administer anesthesia to the patient's left arm. Position A shows
the console positioned for access to the patient's head and both
arms while position B shows the console for access to the patient's
right arm.
FIG. 4 shows how the adjustment capabilities of the surgical table
about pedestal 22 and the movement of the pedestal through an arc
defined by radial arm 32 can cooperate in the movement of the
surgical table. In this respect, FIG. 4 shows a portion of a
hospital operating room 44, an anesthesia room 46 and a patient
corridor 48. The opening 50 from the patient corridor to the
anesthesia room and the opening 52 from the anesthesia room to the
operating room can be closed by any suitable means (not shown) such
as a sliding door. It should be understood that the environment of
the operating room 44 should be as sterile as possible. Patient
corridor 48 is, of course, clean but not sterile. Anesthesia room
46 acts as a buffer between the unsterile conditions in the patient
corridor and the sterile conditions of the operating room.
In the typical arrangement employing the present invention, radial
arm 32 may have its end 36 journaled in the anesthesia room or in
the operating room adjacent the wall between the anesthesia room
and the operating room. FIG. 4 shows in solid line a typical
arrangement for the various components of the present invention
during a surgical procedure. At the end of the surgical procedure,
the motor and drive means 38, 40 shown in FIG. 1 can be activated
to swing radial arm 32 into the anesthesia room to the position
shown in dotted line. Cantilevered arm 14 can then be swung counter
clockwise about pedestal 22 to carry surgical table 12 from the
anesthesia room into the patient corridor as shown in dotted line.
In this position, the patient can be moved from the surgical table
to a hospital bed 54 without the need for rolling a transfer bed or
stretcher into the operating room or anesthesia room. Thus, the
equipment rolling along the floor of the unsterile patient corridor
need never be rolled into the sterile environment of the operating
room.
This process can be reversed when transporting a patient into the
operating room. When moving into the operating room, however, the
surgical table may be held in the anesthesia room and the necessary
anesthesia administered to the patient. Thereafter, the radial arm
is pivoted to move the surgical table and pedestal through opening
52 into the operating room as shown in solid line in FIG. 4.
Thus, it will be appreciated that the present invention
accomplishes its intended objects in providing a surgical table
which is relatively mobile within the operating room, to the side
of the operating room, into an anesthesia room, or into the patient
corridor for a transfer of the patient to or from a hospital bed.
Having the surgical table mounted in cantilever fashion permits the
surgeon and assistants to move close to and around the surgical
table and also frees the entire area beneath the table for access
by x-ray apparatus or other equipment. All of the cords, hoses,
etc. supplying services to service console 24 are enclosed in arm
32 which greatly reduces the danger to personnel in the operating
room.
While the services are shown entering the operating room through
the floor, it is possible to run cords and hoses 30 from the
ceiling through a vertical column and then journal radial arm end
36 to such a column.
