2,406,393 TWEEZER IMPLEMENT AND THE LIKE Edwin A. Neugass, Port Chester, N. Y. Application September 27, 1943, Serial No. 503,898 i Claim. (01. 81-43) This invention relates to improvements in use tweezers in conjunction with electrical instrutweezers, and more particularly in the type emmerits, such as, cauteryQand high frequency desicployed for removing hair or hair-like substances cation instruments. The di-electric properties of frombodies. The invention also is applicable for tweezers made in accordance with the present inuse in connections with pliers, tongs, forceps, vention will prevent any mishap through shock. speculums, and similar devices. Furthermore, such tweezers are particularly It is an object of the present invention to prouseful in removing shrapnel d other forei vide tweezers, at least the jaw portions of which bodies from wounds and because of their bility are transparent enabling the extent and condito grasp irregular objects may be well used in field U hospitals during armed conflicts.

These and other objects and advantageous fea- It is a further object of the present invention tures of the invention a d the means for their to combine in tweezers the characteristics of attainment will be more apparent from the fo1- light transmitting, as well as yieldability or coml wing d i d p n t ken i c nec o pressibility at the points of contact thereof with if) With the accompanyingdrawing, illustrating. certhe hair Or other object to be grasped, lifted or tainembodiments of which the invention ma be removed, thus preventing injury of the object realized, and in which:

In Fig. 2, the numeral lea represents a hair Where the tweezers are made in one integral being i by jaws Ila and Ma of tweezers piece of plastic material, the natural resiliency of ii d in accordance with the inVentiOh.

Where the tweezersare made with it hall" not y e p ted f om being wide jaws of clear plastic, it will be possible to (flushed, whlle 1n gripping engagement with the view the extent of the object grasped or the size Jaws, P also, h slllffaces 0f t laws In comor nature of the grasped object through the Side tact with the hair W111 be greater than that seen all of th tweezers in the conventional example shown in Fig, 1.

Since plastics are non-magnetic, it becomes Figs- 3 and 4 Show tweezers having the possible to use the tweezers in conjunction with ventional bifurcations it connected t gether at magnets and, yet retain its freedom of movement the end l8, in any suitable manner and by y or motion, as the tweezers will not be attracted suitable means. These bifurcations It may .be by the n t. provided with a non-slip gripping surface I8, such In surgical applications it is often necessary to as, knurling, etc. The end 19 of each bifurca V 3 1 tion is preferably provided with a clamping member 20 riveted .at 2| to the bifurcations l6. Clamping member 20 has an offset 22 thus forming a slot or pocket 23 between it and the end IQ of the bifurcation 16, which receives the reduced end 24 of the non-metallic, preferably plastic jaw member 25, the latter being secured in space 23,

as by a rivet 26. The free ends 21' of the jaws 25 may be of conventional shape.

The tweezers may be made entirely of nonmetallic,- plastic material, such as, for example, the one indicated by the numeral 30 in Fig. 5.

In this embodiment, the tweezers may comprise the bifurcated members 32 joined together at body portion 3|, each bifurcation being conventionally shaped at its free end 33; ,Tweezers30 may be formed from a single piece of material by machining or molding. The jaws 25 (Figs. 3, 4)- may be formed by machining or molding.

The jaw members 25 of Fig. 3 and the tweezers 30 of Fig. are made of plastic composition having embodiedtherein the desired compressibility for the purposes intended. Examples of utilizable materials are, methyl methacrylate plastic, 7

Celluloid, cellulose acetate, polystyrene, pyroxylin, other ethers and esters of cellulose or hornlike materials or synthetic resinous compounds having approximately the physical properties of cellulosic materials or methyl methacrylate. Where the jaws or tweezers are molded, the method of molding may be flash, compression, extrusion or injection.

A material very suitable, for the purpose intended comprises an organic plastic, such as, the methyl methacrylates, since this material embodies two desirable characteristics, namely, transmissibility of light through the material and the softness or compressibility required at the jaw portions of the tweezers to grip the hair or other objects without injury thereto. This material is lighter than glass, non-breakable, strong and durable and'oifers resistance cals and oxidation.

It will thus be seen that there has been provided by this invention tweezers and the like in which the various objects hereinabove set forth, togetherwith many thoroughly practical advantages, are successfully achieved. I V

As many possible embodiments maybe made of the above invention, and as many changes might be made in the embodiments is to be understood that all matter hereinbefore set forth or shown in the accompanying drawing is to be interpreted as illustrative and not in a limiting sense.

Having thus described my invention whatis claimed as new, and desired to be secured by Letters Patent, is;

A surgical appliance comprising a pair of tweezers having a bifurcated body, a member secured to the end of each bifurcation of said body, said member having'an offset forming between it and the end of said bifurcation a slot, a tapered jaw member projecting within said slot and being secured to said first-named member and said bifurcation, each of said jaw members being made of compressible and transparent organic plastic material, the compressibility of the material enabling said jaw members to engage an objectbeing grasped thereby and therebetween, and the transparency of said jaw members enabling the extent and condition of said object being revealed a through the jaw members.

to most chemi above set forth, it.
