Abstract

DISPOSITIVO DE TRATAMENTO MÉTODO DE FIBRA ÓPTICA DE EMISSÃO ASSIMÉTRICA DE RADIAÇÃO FORA DE EIXO E MÉTODOS DE TRATAMENTO PARA ESCAVAÇÃO OU ABLAÇÃO DE CAVIDADE EM TECIDO HUMANO OU ANIMAL. Um dispositivo e um método aperfeiçoados para procedimentos cirúrgicos seguros, precisos e eficientes são divulgados. O dispositivo divulgado é um conjunto de fibra óptica com uma configuração de extremidade distal assimétrica compreendendo uma fibra de ponta dobrada com uma luva fundida como uma parte integrante dela, colocada na extremidade distal (saída) da fibra e com um conector rotativo no lado proximal (entrada). A ponta da fibra e a superfície de contato com o tecido localizada na extremidade distal da ponta podem ser construídas com configurações de forma diferentes, tal como ponta convexa para melhorar as característica de focalização, ponta côncava para atingir irradiação divergente ou uma ponta de feixe expandido para atingir um efeito semelhante áquele obtido por ferramentas eletrocirúrgicas. Um aperto garante e intensifica a capacidade de torce e girá-la facilmente. Em outra modalidade preferida, manobras de torção são aprimoradas pro meio de uma configuração especial. Ambos os aspectos especiais (ponta dobrada e conector rotativo) permitem tratamento melhorado e aprimorado de patologias diversas, tornando possível alcançar eficientemente e facilmente e tratar tecido específicos. A capacidade orientação, a capacidade de torção e a rotação da fibra óptica levam a um efeito mais preciso melhorado nos tecidos. Devido a isto, tratamentos mais fácies, mais rápidos e mais precisos e eficazes pode ser executados pelos seus meios. Por exemplo, ela pode ser inserido em um cistoscópio para realizar ablação de alta potência de tecido prostático para tratamento de BPH, ou orientada para um dos lóbulos prostático que podem ser escavados por dentro a fim de aliviar a pressão na uretra enquanto mantendo a integridade de uretra. Outros usos podem ser a remoção de tumores, tecido hiperplásico ou outro tecido indesejado do corpo. O conjunto de fibra ótica divulgado pode ser usado com fontes a laser de vários comprimentos de onde, incluindo fontes de laser duias, mas também dispositivos de LED de energia mais alta ou fintes de luz muito brilhantes podem ser usados para gerar a radiação a ser transmitida também. Devido a este novo projeto, a fibra descrita é fácil de colocar no lugar, também é fácil de de manter em contado com tecido e altamente durável. A sensação para o médico é grandemente melhorada também. Isto resulta em transferência de potência mais eficaz para tecido e, por conseguinte, os procedimentos são mais confiáveis e os tempos de procedimentos são cortados em até 30%.
