Abstract
<B>ELETRODO ELETROCIRúRGICO DE RETORNO REUTILIZáVEL PARA USO EM ELETROCIRURGIA<D> Eletrodo eletrocirúrgico de retorno reutilizável para uso com eletrocirurgia. Em uma modalidade ele inclui uma área de apresentação ou de superfície de trabalho variando de cerca de 100 centímetros quadrados a cerca de 20.000. Em outra, a superfície de trabalho é pelo menos tão grande como aquela de uma projeção de cerca de metade do perfil do tronco de um paciente. Em outra ainda, ela inclui uma área de superfície de trabalho pelo menos tão grande como aquela de uma projeção do perfil tanto do tronco como das pernas de um paciente. Ela é adaptada para disposição na superfície de trabalho de uma mesa cirúrgica ou cadeira de dentista imediatamente subjacente a um paciente durante eletrocirurgia. Apresentando-se uma área de superfície de trabalho muito grande, a necessidade de um contato direto ou contato através de géis é eliminada; através do emprego de áreas de superfície laváveis, ela é pode ser prontamente limpa e reutilizável; e através da seleção de características de resistência para os materiais do eletrodo do corpo principal do eletrodo. Através da projeção das geometrias do eletrodo, ele torna-se autolimitante tal como para densidade de corrente, e aumento de temperatura de forma a evitar trauma do paciente. Um manguito opcional é fornecido para uso cooperativo com o eletrodo.<B> REUSABLE RETURNABLE ELECTROSURGICAL ELECTRODE FOR USE IN ELECTROSURGERY <D> Reusable return electrosurgical electrode for use with electrosurgery. In one embodiment it includes a presentation area or work surface ranging from about 100 square centimeters to about 20,000. In another, the work surface is at least as large as that of a projection of about half the profile of a patient's trunk. In yet another, it includes a work surface area at least as large as that of a profile projection of both a patient's torso and legs. It is adapted for placement on the work surface of a surgical table or dentist's chair immediately underlying a patient during electrosurgery. With a very large work surface area, the need for direct contact or contact through gels is eliminated; through the use of washable surface areas, it can be readily cleaned and reusable; and by selecting resistance characteristics for the electrode materials of the main electrode body. Through the projection of the electrode geometries, it becomes self-limiting as for current density, and temperature increase in order to avoid trauma to the patient. An optional cuff is provided for cooperative use with the electrode.
