Abstract: A single ultrasonic surgical apparatus can provide a substantial cutting effect on tissue, a substantial coagulation effect on tissue, and an appropriate blend of simultaneous cutting and coagulation effects on tissue. The ultrasonic surgical apparatus is comprised of a handpiece which incorporates a transducer and a surgical tool, a source of electrical energy, a controller, and a switch. The apparatus may be operated at two frequencies within the ultrasonic spectrum, where the first frequency is selected at the low end of the spectrum for enhanced tissue cutting performance, and the second frequency is approximately three times higher for enhanced tissue coagulation performance. The two frequencies may be operated selectively or concurrently, and may be independently adjustable as to amplitude. The transducer may be composed of magnetostrictive or piezoelectric elements. The surgeon to set the desired amplitude of the mechanical vibrations. The transducer is mounted within the handpiece at a location that corresponds to a vibration node common to both the first frequency and the second frequency. Also claimed is a method for use, including the steps of: developing an ultrasonic resonance at a first frequency; developing an ultrasonic resonance at a second frequency which is approximately three times greater than the first frequency; resonating an ultrasonic transducer at the first frequency concurrently with the second frequency; and supporting the transducer where the nodes of vibration at the first frequency are substantially coincident with the nodes of vibration at the second frequency.

Abstract: An electrosurgical tip for the application of electromagnetic energy in either a monopolar or a bipolar circuit through the tissue and the bodily fluids of an animal or human has a metallic electrically and thermally conductive electrode for connection to an electrosurgical generator proximally and for transmission of the electromagnetic electrosurgical energy to the tissue and the bodily fluids of the animal or human distally. A sheath of heat shrinkable fluorinated polymeric substance is an electrical and thermal insulator held about the electrode for preventing the flow of electromagnetic and thermal energy from the metallic electrically and thermally conductive electrode to the tissue and the bodily fluids. A smooth surface of the sheath contacts the tissue and the bodily fluids and has a low surface free energy. Openings through the sheath extend from the electrode to the surface for permitting the passage of energy. A wall of the sheath is of a thickness adequate to space the electrode from substantially any contact with the tissue and isolate heat due to the arcs. A ceramic substance is an electrical and thermal insulator about the conductive electrode for preventing the energy flow. A method of making the tip includes covering the electrode with the insulator, isolating physically the heat generated due to the passage of energy. A method of using the tip places the surface in close proximity to the tissue and the bodily fluids, transmits the electromagnetic energy through the openings, allows cleaning tissue and bodily fluids from the surface. The use includes first passing energy through openings in a wall of electrical and thermal insulation and application of electromagnetic energy by either a monopolar or a bipolar circuit relative to the tissue and the bodily fluids of an animal or human.

Abstract: Un aparato quirurgico ultrasonico sencillo puede proporcionar un efecto de corte substancial sobre el tejido, un efecto de coagulacion substancial sobre el tejido y una combinacion adecuada de los efectos de corte y coagulacion ismultáneos sobre el tejido; el aparato quirurgico ultrasonico está formado por un mango que incorpora un transductor y una herramienta quirurgica, una fuente de energía eléctrica, un controlador y un interruptor; el aparato puede hacerse funcionar a dos frecuencias dentro del espectro ultrasonico, seleccionándose la primera frecuencia en el extremo inferior del espectro para potenciar el comportamiento de corte del tejido y siendo la segunda frecuencia aproximadamente tres veces superior para potenciar el comportamiento de coagulacion del tejido; las dos frecuencias pueden funcionar de forma selectiva o concurrente y pueden ajustarse de forma independiente segun la amplitud. El transductor puede estar formado por elementos magnetoestrictivos o piezoeléctricos; el cirujano selecciona la amplitud deseada de las vibraciones mecánicas; el transductor está instalado dentro del mango en una posicion que corresponde a un nodo de vibracion comun a la primera frecuencia y a la segunda frecuencia; además se reivindica un procedimiento de uso, que incluye las etapas de: desarrollar una resonancia ultrasonica a una primera frecuencia; desarrollar una resonancia ultrasonica a una segunda frecuencia que es aproximadamente tres veces superior a la primera frecuencia; sintonizar un transductor ultrasonico a la primera frecuencia de forma concurrente con la segunda frecuencia; y alojar el transductor donde los nodos de vibracion a la primera frecuencia sean prácticamente coincidentes con los nodos de vibracion a la segunda frecuencia.
