Description

CANETA DE BISTURI  BISTURI PEN
A presente invenção refere-se a uma caneta de bisturi, particularmente usada em cirurgias minimamente invasivas. The present invention relates to a scalpel pen, particularly used in minimally invasive surgeries.
Histórico da inovação  Innovation History
A exposição que segue, por simplicidade de explicação, ilustra a inovação dentro de uma realização particular, qual seja, uma caneta de bisturi usada em bisturis elétricos sem que por esse motivo esteja restrita a apenas aos elétricos, podendo ser usada em bisturis eletrônicos, ultra-sônicos, bipolares, etc.  The following discussion, for simplicity of explanation, illustrates innovation within a particular embodiment, namely a scalpel pen used on electric scalpels without being restricted to electric scalpels only, and can be used on electronic, ultra scalpels. -sonic, bipolar, etc.
É do conhecimento do homem da técnica o uso de bisturis elétricos para executar cortes ou cauterizar partes do corpo humano. Esses aparelhos são vantajosamente utilizados pois reduzem a perda de sangue durante a cirurgia, ao mesmo tempo em que efetuam a incisão cauterizam o local.  It is known to man in the art to use electric scalpels to perform cuts or cauterize parts of the human body. These devices are advantageously used because they reduce blood loss during surgery, while making the incision, cauterize the site.
O bisturi compreende uma caneta que é o objeto manipulado pelo cirurgião para fazer a cirurgia. Ela é elemento alongado, pequeno, leve, ergonómico, e de fácil manuseio. A caneta possui uma abertura em sua extremidade frontal, através da qual são inseridas a agulha ou lâmina, para as cauterizações ou corte.  The scalpel comprises a pen that is the object manipulated by the surgeon to perform the surgery. It is elongated, small, lightweight, ergonomic, and easy to handle. The pen has an opening at its front end through which the needle or blade is inserted for cauterization or cutting.
Qualquer que seja o tipo de cirurgia a iluminação deve ser adequada para permitir uma boa visão do local.  Whatever type of surgery the lighting should be adequate to allow a good view of the site.
Ocorre que geralmente a iluminação do local encontra-se acima da mesa cirúrgica, sendo ineficiente pela distância, estrutura e posicionamento do cirurgião, agravando-se quando se trata de pequenas incisões, ou seja, das cirurgias minimamente invasivas.  It happens that the illumination of the place is usually above the operating table, being inefficient by the distance, structure and position of the surgeon, worsening when it comes to small incisions, ie minimally invasive surgeries.
Nessas situações é comum o cirurgião utilizar um dispositivo de luz ao redor de sua cabeça com a luz voltada para o paciente, ou ainda, ter a ajuda de um assistente que segura uma fonte de luz, direcionando-a para o local da cirurgia, conforme o cirurgião solicita. Mas nenhuma dessas opções é muito adequada, pois a primeira situação requer do cirurgião um constante controle do posicionamento de sua cabeça em relação ao local de trabalho. Na segunda, o cirurgião tem de indicar ao assistente a todo instante a posição que deve manter a iluminação, o que desvia sua atenção da cirurgia. In these situations it is common for the surgeon to use a light device around his head with the patient-facing light, or to have the help of an assistant who holds a light source, directing it to the location of the patient. surgery as the surgeon requests. But none of these options is very appropriate, because the first situation requires the surgeon to constantly control the position of his head in relation to the workplace. In the second, the surgeon must indicate to the assistant at all times the position that should maintain the illumination, which diverts his attention from surgery.
A fim de vencer esses inconvenientes a presente inovação trata de uma caneta de bisturi dotada de luz própria que permite que o local tratado seja diretamente iluminado, melhorando a visualização da cirurgia.  In order to overcome these drawbacks the present innovation deals with a self-lit scalpel pen that allows the treated site to be directly illuminated, improving the visualization of the surgery.
É também um objetivo da presente inovação uma caneta de bisturi que, por sua estrutura de iluminação direta, possibilita otimizar não somente as cirurgias minimamente invasivas mas também as tradicionais.  It is also a goal of the present innovation a scalpel pen which, by its direct illumination structure, makes it possible to optimize not only minimally invasive but also traditional surgeries.
É ainda um objetivo da presente inovação um bisturi com auto-iluminação mais eficiente, pois ilumina a o local da cirurgia, dando ao cirurgião maior precisão de iluminação, trazendo assim ganho de tempo cirúrgico, uma vez que não haverá a necessidade de ajuste de foco central, pois a caneta necessariamente sempre aponta para o local em tratamento .  A more efficient self-illuminating scalpel is also a goal of the present innovation, as it illuminates the surgical site, giving the surgeon greater illumination accuracy, thus bringing surgical time savings, since there will be no need for central focus adjustment , because the pen always always points to the place under treatment.
A redução do tempo operatório, por consequência, beneficia o paciente pois diminui sua estadia na sala cirúrgica, reduzindo o risco de contaminações, diminui custos pela redução de tempo da utilização da sala cirúrgica, e ainda,proporciona uma maior rotatividade nos centros cirúrgicos.  The reduction in operative time, therefore, benefits the patient by reducing their stay in the operating room, reducing the risk of contamination, reducing costs by reducing operating room time, and also provides greater turnover in operating rooms.
