Abstract

A vacuum hood attachment for electrosurgical instruments has a hollow tubular body open at each end and a side opening for connection to a source of vacuum. One of said end openings is to be fitted on the end of an electrosurgical instrument of a pencil- or pen-like or other hand held construction having an electrocauterizing or electrocutting blade secured therein. The other open end of said tubular body surrounds the blade along part of the length thereof. On connection to a source of vacuum during use, the hood attachment withdraws vapors and smoke from an operating site to keep the same clear for observation by the surgeon. This hood attachment fits a variety of shapes of electrosurgical instruments and may fit around the end of the instrument and/or into a recess in the end of the instrument depending on the construction of the instrument. The hood attachment may be secured by friction fit or clamped, wedged or cemented into place. Depending on the design of the electrosurgical instrument, the hood attachment may be cylindrical in shape or may be tapered or may have a portion to be fitted into a recess on the instrument. The hood attachment may be fixed in operation, and may have a portion constructed for extension and retraction.
