An inexpensive, disposable heating element is prepared for medical applications using layers of biologically-compatible materials disposed about a heating element that is formed of an electrically conductive material which exhibits positive temperature coefficient of resistance and that is then operated by a power controller which responds to the resistance of the heating element or to other electrical indication of operating temperature in order to control the level of power supplied to the heating element. A fuse is distributed about the periphery of the heating element to disconnect electrical power from the heating element in response to excessive heating of the element attributable to a portion of the heating element, usually including the periphery, not being immersed in liquid being warmed. A connector to the heating element may include a tab that retains coded manifestations thereon of a measured parameter of the heating element, which manifestations may then be detected upon insertion of the connector into a receptacle of a power controller to provide programming signals that set the operating parameters within which the power controller operates the heating element. A flow controller may be disposed adjacent a surface or surfaces of a heating element to confine the flow of a liquid in a selected pattern over the surface or surfaces of the heating element.

Method and heater apparatus with protective fuse for medical applications

An improved electrocautery method and instrument includes interlock features which enable the instrument to be safely operated under convenient manual controls including a slide element and control buttons and interlock switch positioned on the instrument.

Extendable electrocautery surgery apparatus and method

Apparatus for warming a sterile liquid includes a basin with a heater assembly, a base surrounding the basin, and an electronic temperature controller. The shape of the basin bottom includes an plateau-like elevated central region and a depressed surrounding rim. The heater assembly is of a thin-film type, and provides relatively greater heating in the central region than in the outer region. Both the heater geometry and the shape of the basin bottom promote a natural and uniform convective flow of the liquid to promote mixing of the warmer and cooler portions of the liquid. The temperature controller allows the user to select the temperature that the liquid is to be warmed to, and provides visual and aural indications of liquid or basin temperatures which exceed reasonable pre-set limits. The controller also halts the flow of electrical current to the heater assembly when an overtemperature problem in the liquid or the basin is detected. A disposable cable connects the temperature controller to the basin.

Heated basin

An improved electrocautery method and instrument is configured to accept attachable extension units for effectively extending the utility of the instrument into deep surgical sites. Interlock features enable the instrument to be safely configured to any desired length for use as a vacuum probe and as a self-cleanable electrocautery or electro-surgical instrument under convenient manual controls including a slide element and control buttons and interlock switch positioned on the instrument.

An improved electrocautery instrument includes a manually retractable-extendable electrode-blade with a vacuum channel disposed therebeneath. A guide in close-spaced relationship to the electrode-blade at the end of the instrument facilitates the scraping off and cleaning of the blade-electrode as it is retracted out of the way to configure the instrument for use as an uncluttered vacuum wand.
