SURGICAL INSTRUMENT CASE
Abstract
A container for surgical instruments having opposed porous
plastic blocks to retain the instruments therebetween. The
container together with the blocks and instruments may be
sterilized and carried about without disturbing the relative
positions of the instruments contained therein, and prevents their
hitting against each other and being damaged.

Claims
Having thus fully described the invention, what is claimed as new
and desired to be secured by Letters Patents of the United States,
is:
1. A surgical instrument case comprising a rigid hollow housing
consisting of opposed tray-like members, a plurality of openings in
the tray-like members communicating with the interior of the
housing, a porous resilient block in each of the tray-like members,
hinge means interconnecting the tray-like members in abutting
relationships and a latch for the tray-like members.
2. A case according to claim 1 in which the resilient blocks are
coextensive with the area defined by the interior of the tray-like
members.
3. A case according to claim 1 in which the resilient blocks are
formed of foamed polyurethane.
4. A case according to claim 1 in which the tray-like members
comprise a rectangular planar portion and upstanding walls around
the margins of said planar portion.
5. A case according to claim 4 in which the hinge means is secured
to a pair of opposed walls on one side of the case and the latch
engages the opposite sides of the case.
Description
BACKGROUND OF THE INVENTION
Surgical instruments are sterilized prior to use, by placing them
in an autoclave. Following sterilization they are then placed upon
a tray for use by the surgeon. The instruments are disposed upon
the tray in a sequence which is related to the surgical steps to be
performed and many surgeons have their individual preferences as to
the arrangement of instruments for specific types of surgery. In
present day procedures the instruments are placed in the autoclave
in random sequence and thereafter arranged upon the tray for use by
a nurse or trained technician. The results are not always in
conformity with the surgeon's preferences.
Accordingly, it is an object of the present invention to provide a
case for surgical instruments which will keep them in a preferred
arrangement during and after sterilization.
Another object of the present invention is to provide a case for
surgical instruments which will withstand the high temperatures of
sterilization.
A feature of the present invention is its use of resilient porous
blocks to retain the surgical instruments while permitting them to
be sterilized.
A further feature of the present invention is its rigid case
structure which may be placed within a sterilizing compartment with
the instruments therein.
SUMMARY OF THE INVENTION
A surgical instrument case according to the present invention
comprises a rigid hollow housing formed of opposed tray-like
members. The tray-like members are secured together along one of
their margins and a latch is provided for securing the trays in a
closed position when the instruments are not in use. Each tray
carries a block of porous resilient material therein, which blocks
secure the surgical instruments therebetween when the case is
closed.
DESCRIPTION OF THE DRAWING
In the accompanying drawing, forming part hereof, similar parts
have been given identical reference numerals in which drawing;
FIG. 1 is a somewhat isometric view of a surgical instrument case
made in accordance with the present invention, in the open
position.
FIG. 2 is a view similar to FIG. 1, in a closed position.
FIG. 3 is a sectional view, somewhat enlarged, taken on line 3--3
of FIG. 2 looking in the direction of the arrows.
FIG. 4 is a fragmentary cross-section of the case in a closed
position.
GENERAL DESCRIPTION
Referring to the drawing, 10 indicates a surgical instrument case
having a hollow housing 11. The housing 11 is made up of two
tray-like members 12, 13, each consisting of a rectangular planar
portion 14 and opposed upstanding walls 15, 16, along the margins
thereof. The planar portions 14 of each tray-like member 12, 13 are
provided with a plurality of openings 17 which communicate with the
interior of the trays. The trays 12, 13 are made of a rigid
material capable of withstanding the temperatures of sterilization.
Metals such as stainless steel, aluminum, etc. are particularly
suitable for this purpose.
A block of resilient porous material 18 such as foamed polyurethane
is carried within each of the tray-like members 12, 13. Foamed
polyurethane or any porous plastic which will allow the sterilizing
medium to pass through it and reach the surgical instruments 19 is
suitable in the practice of the present invention. The resilient
blocks 18 are also of a size and thickness to fill the entire space
within the housing 11 when it is closed.
A hinge 19 is secured to the tray-like members along two of the
opposed walls 16 as shown in FIGS. 3 and 4. The hinge 19 permits
the case to be opened as shown in FIG. 1 for loading purposes and
for instrument access during use. The hinge also secures the trays
in abutting relationship as shown in FIGS. 2 and 3 when the case is
closed.
The tray-like members 12, 13 are locked together, when the
instruments 19 are not in use, by a latch 20 swingably secured to
the housing 11.
The manner in which the surgical instrument case is used will be
apparent from the foregoing. With the case in the open position of
FIG. 1, the surgeon places the instruments he desires for a
particular operation upon the resilient block 18 in the preferred
arrangement and order. The case is then closed and latched shut.
The resilient blocks 18 surround the instruments and keep them from
shifting from their desired position. The case 10 is then placed in
an autoclave. As a result of the construction of the case 10, the
sterilizing medium passes through the openings 17 in the tray-like
members, through the resilient blocks 18 and to the instruments 19
as indicated by the arrows 21.
The sterilized case 10 and the instruments therein are removed from
the autoclave and placed within easy reach of the surgeon. The case
can remain closed until the instruments are needed.
From the foregoing it will be seen that there has been provided a
surgical instrument case which lends itself to a wide variety of
instrument arrangement for various types of operations. Once
arranged, the instruments therein will remain in place despite the
necessary handling thereof during sterilization procedures.
