Abstract: A disposable dermal curette for scraping lesions from the surface of a patient's skin, comprising a generally cylindrical plastic handle having a proximal end portion, a distal end portion and a mid-section portion therebetween. The curette has a substantially flattened annular working element attached to the handle, the working element having a hoe-shape, substantially planer configuration and arcuate walls projecting therefrom to the handle and attached thereto. The arcuate walls extend from the planar cutting surface having a radius sufficient to minimize gouging as the cutting surface is moved along the skin to remove lesions therefrom.

Abstract: This is directed to a smoke evacuator for use in electro surgery and laser surgery to collect smoke and surgical debris which includes body portion, a flared horn portion to promote flow of smoke and surgical debris into the body portion and a filter positioned on the body portion to remove particulate matter contained in the smoke and surgical debris.

Abstract: A smoke evacuator for use in electrosurgical and laser surgical procedures in which a source of rapidly moving fluid under pressure is introduced to a surgical site to entrain smoke and other surgical debris generated during the procedure and a collection element operated under reduced pressure. The latter is positioned adjacent to the surgical site so that the moving fluid stream entrains all of the smoke and surgical debris which is then collected in the collection element. In the preferred embodiment of the invention, the collection element includes a flared horn portion to ensure laminar flow of the fluid stream as it enters the collection element. In accordance with another embodiment of the invention, the source of fluid under pressure and the collection element are mounted on a laser surgery handpiece or probe whereby the fluid pressure source and the collection element are integral with the probe and thus the tube is repositioned as the probe is repositioned.
