Description

'I UNrrnD PATENT Faroe.' s

GEORGE N. PALMER, OF GREENE, NEW YORK.

IMPROVEMENT lN-INSTRUMENTS FOR OBLITERATING STRICTURES IN DUCTS 0R NATURAL PASSAGES y A FOR ANIMALILUIDS.

Specification forming part of Letters Patent No. 68,647, dated Septombcr l0, 1867.

To all whom it may concern:

Be it known that I, GEORGE N. PALMER, of

thetownV of Greene, in the county of Chenantube of the instrument with the slide or roddrawn so that the blades or laneet-points are incased within the sheath. Fig. 2 shows a view of the same with the slide-rod forced in, showing the cuttingblades or lancet -points thrown out for operating.

The object of my invention is an improve ment in surgical instruments for the purpose ot' removing or obliteratin g strictures or con-y tracted ligaments in ducts or natural passages for animal fluids. i

My invention consists in a smooth, closed, conical-pointed tube, in which is iitted a piston-rod, in which, also, are titted and pivoted two or more concealed lancet-points or blades, which can be thrown out of the small open-l ings near the point of the tube or sheath at pleasure, so as to make the incision in a d uct or passage ou opposite sides instantly at the same time.

'To enable others to make and use my invention, I will describe it more fully, referring to the amended drawings and to the letters thereon.

The tube or sheath A may be made of silver or other suitable metal, the diameter ot' which for most purposes should be quite small-not to exceed three-sixteenths of an inch-coneshaped, and closed at the point a, and very smooth, with rings or handle B B to control its operation. At a short distance from the point a of the tube A, I make narrow slits or openings b b on opposite sides, and near to them, at a right angle, maybe two more slits, c o, if desirable, for any specitic purpose. Into the sheath or tube A is fitted a rod of metal,

D, to slide, it having at one end a head or knob, E, and a smaller guide-pin, e, to workin a slit, d, in the sheath A, so that the rod D is always in one position in the sheath or tube. At the right distance from the knob E to match the openings b b and c c in the sheath A are tted in the rod D ytwo or four small cutting-blades or iancet-points,ff, they being pivoted tothe rod D in such a manner asto be entirely folded within the tube A, there being small longitudinal grooves in the rod from the blades ff to the ends, in which are fitted small lips eut and turned in from the point end ot' the slits b and c ofthe sheath A, so that when the rod or piston D is pressed up in the tube A the blades or points ff are guided and forced out through the openings b and c, and are held there at a right angle, firmly braced, as long as the rod D is held up to the knob E against the end of the tube A. When the rod D is started back the lancet-points ff are in stantly withdrawn and concealed within the sheath, as in Fig. 1.

One of the specific purposes for which the above-described surgical instrument is intended is to operate in the orifice ot' the teats of hardmilking cows, and a slide-gage, h, is provided, so that the exact distance the instru ment is inserted into the teat may be known.

lt has been long and well known to dairymen that some of the best cows have so small an orifice in their teats and so firm a ligature that they cannot be milked without extraordii nary strength and a most laborious process, and it often occurs that the most valuable cows and best milkers, from some cause or other, have one or more of their tea-ts apparently closed up by the contraction of the muscle around the oriiice, so that they can only be milked, if at all, by avery stron ghanded man 5 and another fact is well known to dairymen that new niilchcows often have -intlammation in their bags by reason ofthe ducts or passages being contracted and closed up, and no method ot' applying an internal remedy having been discovered whereby to relieve them and draw the milk from lthe udder, they not unfrequently become ulcerated and useless for the season, and many times lost for the dairy for ever. The only resource to remedy the difficulty was found to be in the use of the scalpel to enlarge the oriee in the tent. This proved The sheath or cone-pointed tube A, sliding: to he beneticinl, and to make the operation easy rod D, knob E, and guide-pin e, as constructed and a sete, sure, und permanent thing, I have and arranged, in combination with the pivoted inv( nted and constructed the above-described blades or lancet-points ff, for operatingin the improvementin Surg-ioni instruments, oraJ trol manner as and for the purposes herein set; enr, for this and other purposes for which 'it i forth.

muy lie-applicable. GEO. N. PALMER.

Having thus fully described my invention, Witnesses: what I claim ns new, and desire to secure by' R. M. BINSWELL,

Letters Patent, isi M. S. BARKER..
