Specification of Letters Patent.

Application filed September 8. 1905- Serial No. 277.604.

Patented July 31, 1906.

To all whom it may concern.-

Be it knownthat I, GEORGE THRASH, a citizen of the United States, residing at Hominy, in the county of Buncombe and State of North Carolina, have invented certain newments and its object is to provide in one in- 'dinally upon the tube 1 an strument a dilator, curette, and douche which can be used for dilating and thoroughly scraping and cleaning or treating cavities. p

The invention consists of certain novel features of construction and combination of parts, which will be hereinafter more fully described in the claims.

In the accompanying drawings I have shown the referred form ofmy invention. In said awings, Figure l is a side elevation showing the normal. positions of the parts. Fig. 2 is a similar view showing the springs extended. Fig. 3 is an enlarged view of the lock of the dilator. v Fig, 4 is a section through the device and Fig. 5 is a section on line 5 5, Fig. 1. Referring to the figures by numerals of reference, 1 is a tube 0 en at one end, while its other end is closed y a tip 2 and constitutes a nozzle. Apertures 3 are formed adj acent this tip and constitute outlets for liquid adapted to be fed in asuitable manner to the open end of the tube., The tip 2 extends into the tube and has rooves 4, in which are located the inwardlyent ends 5 of spring-strips 6. These strips extend longitunormally lie flat thereon, their other ends being bent at ri ht angles and extending into engagement wit a sleeve 7, slidably mounted on the tube. A

ring 8 surrounds the tube and the springstrips 6 and is for the purpose hereinafter set forth. I

A handle consisting of a cylinder 9 is suitably secured upon the tube 1 near its inlet end, and secured to this handle is a channeled strip 10, having notches 11 in one edge and an eye 12 at one end. A non-rotatable spring-rod 13 is slidably mounted in the eye and is secured at one end to the sleeve 7,

while its other end has a lateral extension 14, which normally engages one of the notches 1 1.

In using this instrument the same is first connected to a li uid-su ply by means of a tube, (not shown, and tl e sleeve 7 is slid toward handle 9. The spring-stri s 6 are thus drawn taut and caused to lie at upon the tube 1. .After'this adjustment the end of the tube is inserted into the cavity to be treated, and sleeve 7 is then slid forward. This causes the spring-strips 6 to bend, as shown in Fig. 2, and they Will dilate the walls of the cavity. The sleeve is slid by means of the rod 13, which extends close to the inlet end of the tube-1. After the proper adjustment of the sleeve the rod-is sprung into engagement with the nearest notch 11, and the parts are thus securely locked. The device can then be rotated so as to cause the strips 6 toscrape or cut away any accumulations or growthsupon the walls, after which suitable liquid is directed through the nozzle and into the cavity. The s ring-strips 6 can be adjusted to cavities oi different sizes by means of ring 8. bowed portions of the springs can be diminished, and by moving it in an opposite direction said bows are increased in size.-

It will be understood that thedevice can be used either as a dilator, curette, or douche or can be utilized for all three purposes simultaneously. Iattach importance to the particular means for adjusting and locking the sleeve, as said means are at all times within convenient reach of the operator.

Having thus fully described my invention,

By sliding this ring forward the 1. The combination with a nozzle having a tip in one end; of spring-strips secured at one end by said tip, a non-rotatable sleeve u on the nozzle and secured to the strips, a note ed locking-strip, a spring-actuating rod secured to the sleeve and extending into and guided by the locking strip, and an extension on said rod adj ustably engaging the notched lockingstri 2 The combination with a nozzle; of 'dilating devices secured to the nozzle, a nonrotatable sleeve mounted on the nozzle and secured to the dilating devices, a handle conrod secured to the sleeve and extending into Within the locking-strip, and an extension 10 and guided by the locking-stri said rod upon the rod adjustably engaging said strip. adapted to be engaged and 100 ed by the In testimony whereof I have signed my strip. name to this specification in the presence of 3. The combination with a nozzle, of ditwo subscribing witnesses.
