    N° 4743 3 A.D.1900 Date of Application, 13th Mar., 1900—Accepted, 28th Apr., 1900 COMPLETE SPECIFICATION. Improvements in Ecraseurs. I, Max Jaenicke, of 32a, Jakobstrasse, Gorlitz, Germany, Doctor Medicinae, do hereby declare the nature of this invention and in what manner the same is to be performed, to be particularly described and ascertained in and by the follow¬ ing statement: — 0 The present invention has reference to certain new and useful improvements in ecraseurs and relates more especially to such as are employed in nasal opera¬ tions, for the removal of polypi and like malignant growths. Hitherto ecraseurs have been so constructed, that the chain saw or wire loop for embracing and removing the polypus has to be formed by hand. 10 This has proved to be a matter of much inconvenience, more particular on account of the time lost on each occasion in adjusting the loop, which moreover, by reason of its being handled must also be disinfected every time and soon wears out. In order to overcome these drawbacks, I employ a special form of guide or 15 mouthpiece for the loop, and a spring device whereby the loop is formed auto¬ matically. In order to make my invention more readily understood, I have illustrated it on the accompanying sheet of drawings, Fig. 1 of which represents a longitu¬ dinal section of an ecraseur according to my invention, Fig. 2 is a detail view to 20 a larger scale, showing the mouthpiece with the wire loop, a is the stem of the instrument, which may be of any suitable cross section and form, and which is provided with a cross bar or ring ad. h is a slide working on the stem a and pro¬ vided with finger rings h1, hl or the like, c is a spiral spring, secured between the slide h and the bottom of the stem a. d is the guide tube for the wire e and 25 is attached to the stem a. This tube is provided with a splayed mouth-piece, which I prefer to form in two branching tubes d1, d2 connected by a bridge d3, as is clearly shown in Fig. 2. In operation the wire e of suitable length, having been inserted into the tubular guide d, d1, d2, its ends are secured to the slide h by means of set screws or in 30 any other suitable manner. Owing to the influence of the spring c the slide will be kept pushed forward and the looped end of the wire will consequently be held protruding from the mouthpiece and will be given the correct shape by reason of the splayed form of the mouthpiece. The instrument is inserted into the nasal or other organ in the usual manner, 35 and the loop having been adjusted over the malignant growth to be removed, the slide h is pulled back whereby the growth is strangled between the loop and the bridge d3. The arched form of the latter ensures a certain and clean operation. Although I have shown only one form of mouthpiece or guide dl, dI3, d3, it is obvious that I may adopt any other suitable form, whereby a broader or narrower 40 loop may be obtained, as desired. In this manner operations may be performed as well at the back as at the front of the nasal organ, and the instrument may readily be passed through narrow passages. The guide and mouth piece may be constructed of two independent tubes, separated from one another at the top bv an insulating bridge piece, whereby 45 the operations niav be performed bv galvano-cauterisation.
