Patented Dec. 15913.
Serial No. 715,35?
To all whom it may concern:
Be it known that I, PASQUALE Roirro, a subject of the King of Italy, residing at Rome, Italy, have invented certain new and useful Improvements in Curet-tes, of which the following is a specification.
This invention relates to surgical instruments, more particularly to that class known as curettes, the object of the invention being to provide an improved instrument of this character simple in construction, comparatively inexpensive to make and exceedingly eliicient in use, and while adapted for various purposes it is in the form shown in the drawings particularly adapted for use in the uterus.
In the drawings accompanying and forming part of this specification Figure l is a perspective elevation of this improvement; Fig. 2 is a side view thereof, and Fig. 3 is a front view of the convex face of the upper part of the curette.
Similar characters of reference indicate corresponding parts in the several figures of the drawings.
In the preferable form thereof shown in the drawings the curette comprises a handle- 2 having a canal or passage 3 therethrough having an olive formed terminus t at its end for the attachment of a tube thereby to permit the irrigation of the surface operated upon by the curette. The handle is provided with a stem or shank 5 through which the canal passes and this stem or shank terminates in a curved port-ion 7 bent to form a concave side 8 and a convex side 9. This curved portion 7 is shown preferably larger at its outer end, the two sides 9' and 10 thereof merging toward the juncture point thereof with the stem and these two sides 9 and 10 are connected at intervals by blades 11, 12, and 13, and these blades are shown arranged in stepped formation along the convex face of the instrument so that the lower one by reason of the curvature of the working end of the instrument projects beyond its next succeeding blade and in consequence they are so situated on the convex face that during the curettage they will all engage simultaneously the concave face of the uterus and during the working of the instrument will also successively engage the surface worked upon and thus insure a uniform and complete curettage, as the blades will pass in succession over the surface worked upon.
It will thus be observed that the curved portion of the instrumenthas in the present instance three blades forming a fencst-ra'ted structure and that the canal through the handle and stem opens below the lower blade. Each of the blades is preferably of curved or arched formation in the present instance, alt iough other formations may be used if desired. In practice the edges of these blades are relatively sharp so as to properly perform the work desired, while the rear edge 15 of the top blade may be relatively dull so that it may be used also as a curette. when it is desired to use a relatively dull edge.
This curette may be made in different sizes and shapes according to the use to which it is to be put, and in practice some of the blades may be dull and others may be sharp as may be desirable, the gist of the improvement being the brovision of a stepped curette.
h iy means of this present improvement a uniform and complete curettage is obtained.
1 claim as my invention 1. A curette having a convex face provided with a plurality of stepped blades.
2. A curette having a concave face at one side and a convex face at the other side, and provided with a plurality of stepped blades on its convex face.
8. A curette having a convex face and a concave face, and provided on its convex face with a plurality of stepped blades, one of said blades having a working edge on the concaved face of the curette.
4. A curette having a plurality of stepped blades each of an arched formation, one above a companion blade.
5. A curette having a plurality of stepped arched formed blades, one wider than a companion blade.
6. A curette having a series of three stepped arched formed blades, one wider than another, with the largest thereof at the outer end of the curette.
7. A curette having a convex face and a concave face and provided on its convex face with three stepped blades each of greater area than the preceding blade, and also having at the top of its concave face a working edge.
8. A. curette comprising a handle and a stem terminating in a curved portion having a plurality of stepped blades.
9. A curette comprising a handle and a stem terminating in a curved portion having convex and concave faces, the convex face being provided with a series of three stepped blades each of greater area than its preceding blade.
10. A trifenestrated curette comprising a handle and a curved portion having a plurality of stepped blades.
11. A trifenestrated curette comprising a handle and a curved portion made up of spaced sides connected by a plurality of blades arranged in stepped formation.
12. A trifenestrated curette comprising a handle and a curved portion made up of 15 spaced sides connected by three curved blades arranged in stepped formation, each succeeding blade being Wider than its pre ceding blade. v
