Abstract
ABSTRACT
A cleaner for cauterizing implements, involving a mounting member one side of which is adapted to be secured by pressure sensitive adhesive to a surgical towel or drape and the other side being provided with upstanding parallel backing strips between which is a pair of mutually adhering flat magnet elements. The magnet elements and backing strips are covered by an abrasive material so that a cauter-izing knife or forcep may be inserted between the magnet elements or wiped against the exposed surfaces.

Description
lOSlZ~
Various knife or razor blade polishing and cleaning devices involve opposed abrasive surfaces urged toward each other by spring force; samples of such devices are disclosed in U.S. Patents 836,189; 1,096,354; 2,648;858 and 3,372,419; and in British Patent 439,086. If the cauterizing implement is flat, similar to a knife or razor blade, the devices disclosed in the above listed patents may be satisfactory, but are not suited for cleaning surgical instruments such as cauterizing forceps, as the closing force increases as the surfaces are separated, resulting excessive force being applied to the cleaning device.
The present invention is directed to a cleaner for cauterizing implements comprising a mounting member having a mounting surface and a pair of upstanding webs flexibly connected to the mounting member; a pair of flat magnet units secured to confronting sides of the webs; a covering including abrasive material over the confronting sides of the magnet units; and the ; magnets exerting a mutually attractive ~orce yieldably maintaining the abrasive covèrings in mutual contact, said force diminishing on separation of the abrasive coverings upon insertion of a surgical implement therebetween.
An object of the invention is to provide a cleaner for cauterizing implements, wherein opposed abrasive surfaces are urged toward each other by magnetic force which decreases in strength as the spacing between the abrasive surfaces increases, so that a cauterizing forcep or the like may spread the abrasive surfaces while reducing rather than increasing the force required to operate the cleaner.
Preferably the cleaner for cauterizing implements is arranged to be mounted on a surgical towel or drape by pressure sensitive adhesive, without danger of being forced free of the towel or drape when used to clean cauterizing forceps.
The present cleaner for cauterizing implements may be made at minimum expense, and thus be discarded after use.

The present invention is directed to a cleaner for cauterizing implements comprising a mounting member having a mounting surface and a pair of upstanding webs flexibly connected to the mounting member; a pair of flat magnet units secured to confronting sides of the webs; a covering including abrasive material over the confronting sides of the magnet units; and the ; magnets exerting a mutually attractive ~orce yieldably maintaining the abrasive covèrings in mutual contact, said force diminishing on separation of the abrasive coverings upon insertion of a surgical implement therebetween.

lOSlZOl The confronting sides of the web portions 6 are pxovided with magnet units 9, each magnet unit including a metal backing strip 10 cemented or otherwise attached to the web portion and a magnet strip 11 cemented or otherwise attached to the backing strip.
It has been found preferable to use magnets formed of sintered magnetic particles bonded togetherby plastic material. For example, magnets formed of ni~rile rubber embedded with particles of ferromagnetic material such as barrium ferrite, a material which is lighter in weight than metal magnets, has been found to be highly satisfactory.
Magnets of this type may be cut to form the elongated magnet strips 11. These magnet strips may be polarized so that one-half of each side constitutes one pole such as South, and the other half constitutes the other side, such as North.
The two magnet strips are oriented in a North-South confront-ing relation with their opposite sides in conect with their respective backing strips to entrance the magnetic force.
Each web portion and its magnet unit is encased in 2~ an abrasive member 12, each abrasive member includes a backing lamination 13 and an abrasive lamination 14. The abrasive members are capable of being folded to form confronting portions 15 covering the magnet strips 11, diverging portions 16 extending upwardly therefrom, folds 17 extending over the upper edges of the web portions 6, opposed exposed portions 18 covering the web portions and end portions 19 covering the ends of the magnet strips and backing strips.
The cleaner for cauterizing implements functions as follows:
The polarity of the magnet strips 11 is such that the confronting portions 15 of the abrasive members are held 10~
in mutual contact, the force of which is predetermined so that the confronting portions will separate and scrape oppo-site sides of a cauterizing knife, when the cauterizing knife is inserted therebetween, guided by the diverging por-tions 16. Usually the cauterizing knife is inserted cross-wise to the web portions 6 and may, after entering between the abrasive members, be turned and drawn longitudinally therebetween, if desired. However, the cauterized material usually is confined to a region close to the tip of the knife `~ 10 so that end-wise insertion is sufficient.
In many surgical operations involving cauterizing implements it is desirable to use a cauterizing forcep.
Such implements have greater thickness than a cauterizing knife, requiring the web portions 6 to spread ~ubstantially, in ~ome cases even to the extent as sh~wn in Fig. 3. In this regard the magnet units serve an important function, for as the magnet units are separated, the magnet force is reduced.
This is desirable for, as indicated, the mounting member is secured to a surgical towel or drape 19 by the pressure sensitive adhesive 7, as indicated in Fig. 4. It is there-fore essential that the surgical implement may engage and be cleaned by the cleaner without applying excessive force that would cause the cleaner to be dislodged from the surgical towel or drape. If it were not for the reduced attraction between the magnets, as occasioned by insertion - of a cauterizing forcep, excessive force might be applied to the cleaner.
Referring to Fig. 3, while the magnetic force exerted between the upper portions of the magnet units reaches virtually zero, there is still residual force between the lower portions of the magnets. In addition, lOSlZOl the foldable connections 5 may be such as to exert a small force tending to urge the web portions 6 toward each other.
In addition to using the confronting portions 15 of t:he abrasive members, as indicated by K in Fig. 6, the exposed portions 18 may also be used to clean a single bald t:ype cautery, or to clean both arms of a forcep simultan-eously, as indicated by F in Fig. 6.
Having fully described our invention, it is to be understood that we are not to be limited to the details here-in set forth, but that our invention is of the full scope -of the appended claims.
