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.

Abstract: The high efficiency filtration particulate and smoke evacuator of the present invention comprises a housing, a filtration means, a nozzle inlet and an air outlet. The filtration means includes a pre-filter to remove particles of intermediate size in conjunction with an odor filter. An ultra low penetration air filter is utilized (ULPA) to remove particles from the air flow down to particles of at least 0.01 microns or larger. Use of the ULPA filter helps to prevent the transmission of communicable diseases by limiting the size of unfilterable particulate matter.

Abstract: The disposable punch of the present invention is of a simple two-piece construction where the first piece is a molded plastic handle portion having an elongated shape designed to be grasped by the surgeon. The handle portion terminates in a recptacle which receives the blade of the biopsy punch. In cross-section, the blade has a crescent shape and terminates in a cutting edge that lies in a single plane. The blade is force fit into the receptacle of the handle portion and is maintained in this position by a friction fit.

Abstract: The disposable punch of the present invention is of a simple two-piece construction where the first piece is a molded plastic handle portion having an elongated shape designed to be grasped by the surgeon. The handle portion terminates in a receptacle which receives the blade of the biopsy punch. In cross-section, the blade has an elliptical shape and terminates in a cutting edge that lies in a single plate. The blade is force fit into the receptacle of the handle portion and is maintained in this position by a friction fit.

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, a mid-section portion with a flattened section recessed relative to the proximal end and distal end portions, and a generally circular or loop-shaped working element, with at least one cutting edge, attached to the proximal end portion. The distal end portion is provided with a textured surface and, for maximum control and proper balance, additional textured surfaces may be provided on the mid-section and proximal end portions.
