Surgical blade abstract
A surgical blade package facilitates the mounting of a surgical
blade on to the forwardly-projecting cleat on a scalpel handle;
and following use in the O.R., the surgical blade package facilitates
stripping the used blade off the scalpel for disposal in a sharps
container. The cleat is inserted beneath the rear end portion of
the blade, and between the blade and the bottom wall of the blade
package; and forward and upward movement of the scalpel snaps the
blade on to the scalpel in a continuous movement. The opposite procedure
is used to demount the used blade from the scalpel and encase it
in the original blade package for disposal in a sharps container.

Surgical blade description
FIELD OF THE INVENTION
The present invention relates to a surgical blade package for safely
mounting a surgical blade on a scalpel handle, thereby avoiding
accidental or inadvertent cuts.
BACKGROUND OF THE INVENTION
In our prior inventions, as disclosed and claimed in our United
States Letters Patents-- 5433321 5528811 5662221 --a blade
package is disclosed and claimed, comprising a molded-plastic closed
"box", wherein the blade is retained by a pivoted flap,
and wherein the forwardly-projecting cleat on the scalpel handle
is inserted downwardly and forwardly into the exposed mounting slot
in the blade to removably secure the blade on the cleat as the flap
is pivoted away to completely disengage the scalpel from the package.
While these earlier patents are fully operational and satisfactory
for the purposes intended, the present invention is the culmination
of further developments and constitutes a substantial improvement
thereon.
SUMMARY OF THE INVENTION
The present invention provides a surgical blade package for more
easily and conveniently mounting a surgical blade on the forwardly-projecting
cleat of a scalpel, thereby substantially minimizing the risk of
injury by an accidental or inadvertent contact with the blade. The
blade has a tip and further has a mounting slot formed therein.
The surgical blade package includes a molded-plastic package having
an open top and sidewalls, a bottom wall, a closed end wall and
an open end oppositely of the closed end wall, respectively. A transverse
ledge is disposed between the side walls, such that the blade is
supported on the ledge between the side walls; the blade is substantially
parallel to the bottom of the package; the tip of the blade is pointed
in the direction of the closed end wall of the package; and the
blade has a rear portion in juxtaposition to the open end of the
package. A hold-down pivotable tab is integrally connected to the
closed end wall by a living hinge. This tab partially covers the
open top for retaining the blade within the package.
An important feature of the present invention is this: The cleat
of the scalpel is inserted through the open rear end of the package
beneath the rear portion of the blade and between the blade and
the bottom wall of the package; the cleat on the scalpel is inserted
into the slot in the blade; and the tab is pivoted upwardly away
from the package as the blade is separated completely from the package.
In a preferred embodiment, the side walls are substantially parallel
and have concavely-formed indented ("scalloped") portions
adjacent to the open end of the package, such that the package may
be conveniently grasped between the thumb and forefinger of one
of the hands of the nurse or technician while his or her other hand
is holding the scalpel, thereby providing additional leverage in
separating the package from the blade on the scalpel.
In another embodiment, the package has an upstanding stud on the
bottom wall thereof; and the blade has a hole formed therein to
receive the stud, thereby positioning the blade laterally of the
side walls of the package.
Preferably, one of the side walls of the package terminates short
of the open end of the package, thereby conforming to a slanted
raised portion of the conventional scalpel handle rearwardly of
the cleat thereon.
Another important feature of the present invention is this: The
blade may be subsequently removed from the scalpel following use
of the blade during a surgical procedure in an operating room or
other medical environment by reinserting the scalpel with the blade
thereon into the original package, thereby stripping the blade from
the cleat on the scalpel; and the tab is pressed down on the blade
to retain the blade, such that the package with the used blade therein
may be placed into a sharps container.
Preferably, cooperating nibs are formed between the pivotable tab
and the package, thereby releasably holding the tab down on the
blade, such that the cooperating nibs are released as the cleat
on the scalpel is mounted into the slot in the blade and the scalpel
is moved away from the package.
A sealed, sterile, pouch may be provided for the blade package.
Viewed in another aspect, the present invention provides, in combination,
a surgical blade package and a surgical blade contained therein,
the blade having a slot formed therein for receiving a forwardly
projecting cleat on a scalpel as the scalpel is inserted into the
package. Following use of the blade in an operating room or other
medical or surgical environment, the blade may be stripped of the
scalpel by reinserting the cleat into the package, thereby eliminating
or at least substantially minimizing the risk of injury by an accidental
or inadvertent contact with the blade. Means are provided for supporting
the blade within the package and for preventing an inadvertent dulling
of the blade during manufacture, shipment or storage thereof, and
releasable means are provided on the package for holding and retaining
the blade prior to insertion of the scalpel into the package. The
scalpel is inserted beneath the rear portion of the blade and between
the blade and a bottom wall of the package, and the scalpel is moved
forwardly and upwardly (not downwardly as in our previous patents)
relative to the package to mount the blade on the scalpel as the
blade is completely removed from the package. After a surgical procedure,
the blade is re-inserted within the package and the relative movement
of the scalpel and package is reversed to strip the blade off the
scalpel; thereafter, the nurse or technician uses the releasable
means to again retain the blade prior to disposal of the package
with the blade into a sharps container or other disposable means.
Preferably, the means for supporting the blade within the package
comprises a transverse ledge formed on the package. In one embodiment,
this ledge is formed between parallel side walls of the package
and intermediately of the length of the package.
The releasable means for holding down and retaining the blade comprises
a tab integrally connected to the package by a living hinge.
Viewed in yet another aspect, the present invention provides a
method of more easily and conveniently mounting a surgical blade
on the forwardly-projecting cleat of a scalpel, and for subsequently
removing the blade from the scalpel following use of the blade during
a surgical procedure in an operating room or other medical environment,
thereby eliminating or at least substantially minimizing the risk
of injury due to an accidental or inadvertent contact with the blade.
This improved method includes the steps of provides a package having
a blade therein, the blade being disposed between respective side
portions of the package and further being recessed below the open
top the package. A tab is formed on the package and partially covers
the open top of the package above the blade. The package is held
with one hand while holding the scalpel with the other hand. The
cleat on the scalpel is inserted underneath the rear portion of
the blade and between the blade and the package. The scalpel is
moved forwardly and upwardly with respect to the package such that
the cleat on the scalpel is received within the slot on the blade,
and such that diametrically-opposite slits on the cleat engage the
respective adjacent sides of the slot in the blade. The forward
movement of the scalpel is continued, such that the tab on the package
is pushed away as the package is separated from the blade and the
blade is mounted on the scalpel.
Following use of the scalpel with the blade mounted thereon during
a surgical procedure, the improved method includes the steps of
picking up the package; maintaining the flap down on the package;
reinserting the blade into the package to completely strip the blade
away from the package; and thereafter disposing of the package with
the blade therein in a suitable container.
In accordance with the teachings of the present invention, the
improved surgical blade package may be used with a standard (unguarded)
scalpel handle or with a guarded surgical scalpel as disclosed and
claimed in our following United States Letters Patents: 5250063
5275606 5411512 5496340 5569291 5662669
These and other objects of the present invention will become apparent
from a reading of the following specification, taken in conjunction
with the enclosed drawings.

GENERAL DESCRIPTION OF THE PREFERRED EMBODIMENTS
With reference to FIGS. 1 6 the improved blade package 10 houses
a surgical blade 11. The package 10 has an open top 12 side walls
13 and 14 a bottom wall 15 a closed forward end 16 and an open
rear end 17. A pivotable tab (or flap) 18 partially covers the open
top 12 and is joined to the package 10 by an integrally-molded "living"
hinge 19. The tab 18 has a raised thumb rest 20. The blade 11 is
supported upon a transverse ledge 21 joining the respective side
walls 13 and 14 intermediately the length of the blade package 10.
The side walls 13 and 14 have indented or scalloped recesses 22
and 23 respectively, adjacent to the open rear end 17 of the package
10 and, preferably, these recesses 22 and 23 are suitable grooved
(or knurled or roughened) as shown for holding the blade package
10 between the thumb and forefinger. The open rear end 17 of the
package 10 (see FIG. 1) has guides 24 and 25 respectively, for
slidably guiding the scalpel into the blade package 10 (as hereinafter
described).
With reference to FIGS. 7A 7D, 8A 8D and 9 the forwardly-projecting
cleat 26 on the conventional scalpel handle 27 is inserted beneath
the rear end portion 28 of the blade 11 and between the blade 11
and the bottom wall 15 of the package 10 (FIGS. 7B and 8B) and the
cleat 26 is continued upwardly and forwardly (FIGS. 7C and 8C) until
the blade 11 snaps on to the cleat 26 on the scalpel 27 and the
blade package 10 is disengaged from the scalpel 27 (FIGS. 7D and
8D) in one continuous upward and forward movement.
With reference again to FIG. 9 the blade package 10 may be pulled
away from the scalpel 27 (all in one motion) or, if desired, the
operator's thumb and forefinger may be shifted into the scalloped
concave recesses 22 and 23 respectively, to assure a better manual
grip and obtain more leverage.
Once the blade 11 has been used in a surgical procedure, the reverse
steps may be employed to re-position the (used) blade 11 in the
original package 10 for disposal purposes.
This reverse procedure is shown in FIGS. 10 14 respectively. Again,
the scalpel 27 (with the used blade 11 thereon) is held in one hand
(FIG. 10) and the blade 11 is inserted into the package 10 (FIG.
11) and continued therein (FIG. 12) to strip the blade 11 off the
scalpel 27 whereupon the blade 11 is wholly within the package
10 and completely removed from the scalpel 27 (FIG. 13) so that
the package 10 (with the used blade 11 therein) may be tossed into
a conventional "sharps" container 29.
With reference to FIGS. 15 18 a modification is illustrated wherein
the transverse ledge 21 on the blade package 10 has an upstanding
pin or stud 30 (or other projection) received in a hole 31 (or other
opening) formed in the blade 11. The cooperation therebetween provides
additional assurance that the blade 11 will not shift laterally
during manufacture, shipment and/or storage of the blade package
10 thereby assuring that the tip 32 and cutting edge 33 of the
blade 11 will not become dulled or nicked.
With reference to FIGS. 19 22 a second modification is illustrated
wherein the pivotable tab 18 has a pair of oppositely-disposed projections
or nibs 34 (FIG. 21) received in cooperating recesses 35 in the
sidewalls 13 and 14 respectively, of the blade package 10 thereby
more securely retaining the pivotable tab 18 against accidental
or inadvertent dislodgement from the open top 12 of the blade package
10. The retaining force of these nibs 34 however, will not interfere
with the upwardly and forwardly movement of the scalpel 27 to mount
the blade 11 on to the cleat 26 of the scalpel 27 and, using the
inherent mechanical advance, pivot the tab 18 away from the open
top 12 of the blade package 10 (FIG. 22).
With reference to FIG. 23 and as is conventional, the side edges
36 and 37 respectively, of the blade 11 (adjacent to the mounting
slot 38 are received in the slits 39 and 40 respectively, of the
cleat 26 on the scalpel 27.
With reference to FIG. 24 the blade package 10 may be received
in a suitable pouch 41 (which is sterilized). In lieu of the pouch
41 a blister pack, foil or other suitable container (not shown)
may be employed for the blade package 10.
As will be appreciated by those skilled in the art, the blade package
10 of the present invention is a decided improvement over the prior
art (including our own patents) and constitutes an important and
valuable contribution in the art. Not only is the operation different
and superior (an upward movement rather than a downward movement)
but, even more significantly, the original blade package 10 becomes
the disposable package or container for the used blade 11.
Obviously, many modifications may be made without departing from
the basic spirit of the present invention. Accordingly, it will
be appreciated by those skilled in the art that within the scope
of the appended claims, the invention may be practiced other than
has been specifically described therein. |
