IMPROVEMENT IN CAUTERIZERS.
Specification forming part of Letters Patent No. 203,387, dated May 7, 1878 application filed V April 12, 1 878. i
To all whom it may concern:
Be it known that we, FREDERICK A. SToHL- g to keep in proper order.
Our invention relates to an improved vessel for holding alcohol, naphtha, or other vaporizable hydrocarbon, whereby the risk of ex plosion or of spilling the liquid is avoided. This is of great importance, so as to prevent accident or interruption during the performance of any surgical operation.
'We heat the cauterizing-instrument by the direct combustion of the hydrocarbon vapors within platina tip, and said tip is in the form of a flattened teat, a knife, a thimble, or a needle, according to the surgical operation that has to be performed. These 'cauterizing-instruments are removable, so as to be changed as required, and the heating-jet and its jettube are surrounded by a shield that prevents the lateral escape of heat.
In the drawing, Figure 1 is a general View of the instrument. Fig.2is a section in larger size of the cauterizer and its jet tube and shield. Fig. 3 is a section of the cauterizingtip at right' angles to that shown in Fig. 2, and Figs. 4 and 5 are detached views of different-shaped cauterizing-instruments.
The bulb a is of usual construction, with an inlet air-valve at b, and a tube, 0, leading to the ex ansion air-vessel c of thin india-rubber, protected by a netting, and acting to maintain a nearly-uniform flow of atmospheric air through the carbureter d. This vessel d is made with an opening at one side, and a screw-cap or plug, d, and it contains cotton or similar fibrous material. The benzine, al-
cohol, naphtha, or other vaporizable hydrocarbon liquid is introduced into this carbureter d only in sufficient quantities to saturate the fibrous material and cause the evaporation of the liquid by the air blown through the same, so as to form a combustible'fluid that can be burned Within the cauterizer for heating the same. There is a hook, 3, upon the carbureter, so as to suspend the same from the button-hole, and a cock, 4, in the flexible tube 5, that leads to the cauterizing-instrument, by means of which the quantity of the combustible material can be regulated.
The cauterizing instrument is composed principally of the tube 0, to which the vapor tube 5 is connected, the handle f, and the canterizing-tip h. At the end of the tube 6 the vapors produced, as aforesaid, issue and are ignited, and burn within the hollow platina cauterizing-tip h, and heat the same.
The manner of using the cauterizing-instrumentin surgical operations, beingknown, does not require further description.
We remark that the hollow flattened teat shown in Figs. 1, 2, and 3 is adapted to some operations. The knife, Fig. 4, and the needle, Fig. 5, are available in other operations.
There is, by preference, a coil or helix of platina wire, at, at the end of the tube 0, which becomes intensely heated, and, by contact with the hollow cauterizer, aids in heating the same.
In order to sustain the cauterizing-tip h, we make use of the two side rods Z Z, that extend back to the handle f, and pass into grooves in the sides of the handle, and are held in place by theclip m, that passes partially around the handle. (See Fig. 6.) This clip can be moved endwise of the handle by the thumb applied to the clip, and in so doing the cauterizing-tip can be drawn back against the platina helix n, or moved away from the same, to regulate the heat.
The tubular shield 10 is made with a head, u, that slides upon the tube 0, and it is pressed forward by the spring 4". There are holes 8 for the escape products of combustion near the back end, and there may be a slide-ring, t, to regulate the size of the escape-apertures. The forward end of this shield slides within the cauterizing-tip when the latter is drawn back toward the heatingjet, so as to prevent the escape of flame or heated gases in the vicinity of the part that is beingcauterized. The side rods Z of the cauterizing-tip h slide through and are guided by this head it upon the tube 6.
-It is often desirable to employ, in.c0nnec- ,tion with this eauterizer, a tubular speculum of a non-conducting material, such as soapstone or asbestus.
We claim as our invention 1. The combination, with the eauterizinginstrument, of a carbureting-vess'el' containing fibrous material and a vaporizable liquid hydrocarbon and an air-forcing bulb, substantiallyas set forth.
2. The cauterizing-tip, made hollow, in combination with the jet-pipe e, shield 9, and means for moving the cauterlzing-tip toward and from the jet, substantially as set forth.
3. The combination, with the cauterizingtip, of the helix n and jet-pipe e, substantially as setforth.
