ABSTRACT:
A disposable hemostatic curette includes a handle, at least one scraping implement, and a crushable applicator. The handle has a first end, a second end, and a length. The cross section and length of the handle are sized to facilitate easy manipulation with a thumb and forefinger. The first end of the handle is tapered to a smaller diameter which is connected to a scraping implement. The scraping implement is preferably round in shape with a shallow bore. A scraping edge of the scraping implement is a sharp edge which is formed from the inner wall of the shallow bore and a tapering outer wall of the scraping implement. A deep bore is formed in the second end of the handle, and is sized to firmly receive the outside diameter of a crushable applicator. The crushable applicator includes a transparent flexible housing, an applicator swab, and a crushable ampule containing a hemostatic solution. At least one crush window is disposed at the second end of the handle. The crush window is an opening through the second end of the handle to the deep bore disposed in thereof. The crush window is sized to allow a thumb and forefinger to break the crushable ampule located inside the crushable applicator which wets the applicator swab.
