P. A. CURREY CURETTE Filed Dec. 1. 1

Patented Aug. 23, 1927.

PINNEY ALFRED CURREY, OF BAKER, OREGON.

GURETTE.

Application filed December It has been claimed by some that the curette shown in Patent No. 865,571, granted on September 10, 1907 fails to accomplish its full measure of usefulness, because there is no adequate means for carrying away the liquid and secretions at the end of the instrument, and because the force of the liquid discharged through the instrument is dissipated, the liquid being discharged otherwise than in the most advantageous manner. The foregoing alleged shortcomings of the instrument shown in Patent No. 865,571, this invention aims to remedy.

It is within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which the invention appertains.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.

In the drawings Figure 1 shows in elevation, an instrument constructed in accordance with the in the body 2. A blade 4 is disposed helically about the body 2 and is joined at its inner edge 5 to the body 2, the blade 4 being joined at one end 6 to the head 3 in a plane AB parallel to the axis of the body 2. The blade 4 is thickened, as at 7, at its outer edge 8, and is tapered as at 9, transversely, from its outer edge 8 inwardly toward its inner edge 5, throughout a portion of the length of the blade, to form a transverse flange 10 on 1, 1926. Serial No. 152,005.

the outer edge of the blade 4, and to form a groove 11 which extends lengthwise of the blade 4. The groove 11 is located between the body 2 and the flange 10. The flange 10 is joined, as at 12, at one end, to the head 3, and closes the groove 11, at a point adjacent to the head 3. The flange 10 is tapered, as at 14, in width, toward that end 15 of the flange which is remote from the head 3.

The flange 10, owing to its peculiar shape, may be used for massaging, with peculiar efliciency, and Without inflicting pain about the place of application. The thickening at 7, and the tapering at 9, not only produce the flange 10, but also form the groove 11 which aids in carrying away the liquid and whatever the curette may loosen.

Another specific improvement in the device consists in so locating the outlet for the stem 1 that a maximum pressure will be obtained, and at the same time, the liquid proceeding through the body 2 will be delivered at the place needed, namely, along the body 2 near to the blade 4, and, especially, into the groove 11. The outlet consists, therefore, of two rows of small openings 16, located on opposite sides of the blade 4 in close relation so thereto, and following the spiral line 5 of juncture between the blade 4 and the body 9, from apoint 17 intermediate the ends of the body, some of the openings, designated specifically by the numeral 18, being located in the head 3.

What is claimed is 1. A curette comprising a stem, including a tubular body and an enlarged approximately spherical head on the end of the body; and a blade disposed helically about the body and joined at its inner edge to the body, the blade being joined at one end to the head in a plane parallel to the axis of the body, the blade being tapered transversely from its outer edge inwardly toward its inner edge, throughout a portion of the length of the blade, to form a transverse flange on the outer edge of the blade, and to form a groove extended lengthwise of the blade 10 and located between the body and the flange, the flange being joined at one end to the head, and being tapered in width toward its opposite end; the stem having an outlet.

2. A device of the class described, constructed as set forth in claim 1, and inrther characterized by the fact that the outlet consists of two rows of small openings located on opposite sides of the blade in close relation thereto and following the spiral line of juncture between the blade and the body from a point intermediate the ends of the body, some of the openings being located in the head.

In testimony that I claim thertoregoing as my own, I have hereto afiixed my signature.

PINNEY ALFRED OURREY.
