Description

"SISTEMA DE ACIONAMENTO DE TURBINA ODONTOLOGICA"  "DENTAL TURBINE DRIVING SYSTEM"
Campo da Invenção Field of the Invention
[0001] A presente invenção se refere a um sistema de acionamento de turbina odontológica, do tipo caneta de alta rotação, caneta de baixa rotação, micromotor odontológico, que prevê que a turbina seja acionada por fluido, reduzindo consideravelmente os níveis de ruído produzidos pela referida caneta quando em funcionamento.  The present invention relates to a high speed stylus, low speed stylus, dental micromotor dental turbine drive system which provides for the turbine to be fluid driven, considerably reducing the noise levels produced by the said pen when in operation.
Antecedentes da Invenção  Background of the Invention
[0002] O cirurgião dentista diariamente, além de ter que conviver com problemas inerentes ao manuseio dos equipamentos odontológicos , está sujeito à exposição de ruídos em seu ambiente de trabalho, especialmente aos ruídos provenientes dos próprios equipamentos que compõem um consultório dentário, principalmente os produzidos pelas turbinas odontológicas , amplamente utilizadas na rotina de um dentista.  The daily dental surgeon, in addition to having to deal with problems inherent to the handling of dental equipment, is subject to noise exposure in his work environment, especially the noise from the equipment that make up a dental office, especially those produced by the dental office. by dental turbines, widely used in a dentist's routine.
[0003] Tais turbinas odontológicas funcionam através de ar comprimido, variando em uma faixa de 230.000 rpm a 450.000 rpm, e os valore médios de níveis de intensidade sonora variam na faixa de 70 a 90 decibéis.  Such dental turbines operate through compressed air, ranging in the range of 230,000 rpm to 450,000 rpm, and the average values of sound intensity levels range in the range of 70 to 90 decibels.
[0004] O nível máximo de ruído permitido pela Organização Mundial da Saúde (OMS) é de 80 decibéis, quando o trabalhador ficar exposto por até 8 horas diárias.  The maximum noise level allowed by the World Health Organization (WHO) is 80 decibels when the worker is exposed for up to 8 hours per day.
[0005] O resultado de uma exposição diária inadequada a médio prazo é a perda auditiva, que ocorre de forma lenta e irreparável. Tratando-se de uma forma lenta, é imperceptível , principalmente porque o ouvido começa a perder sensibilidade a frequências muito altas, sendo que o profissional só percebe a dificuldade auditiva quando a lesão já está em um estágio bem avançado, tornando-se irreversível . The result of inadequate medium-term daily exposure is slow and irreparable hearing loss. Being slow, it is imperceptible, mainly because the ear begins to lose sensitivity at very high frequencies, and the professional only notices the hearing difficulty when the The injury is already at a very advanced stage, becoming irreversible.
[0006] Diante dos problemas expostos acima, os fabricantes de equipamentos odontológicos vem desenvolvendo novas técnicas para superar tais problemas.  Faced with the above problems, dental equipment manufacturers have been developing new techniques to overcome such problems.
[0007] São conhecidos do estado da técnica alguns documentos relacionados a sistemas e turbinas odontológicas , dentre os quais destacamos o documento MU 8500878-8 que se refere a uma disposição construtiva introduzida em caneta odontológica que tem como base a utilização de uma saída canalizadora de ar e ruídos e um conjunto mecânico que produz menos vibrações. A caneta odontológica em questão apresenta em sua estrutura interna um conjunto de rolamento diferenciado em relação ao conjunto convencional utilizado nos modelos conhecidos no estado da técnica. Esse conjunto de rolamento diferenciado é formado por esferas intercaladas com outras esferas de menor diâmetro, e que são apoiadas em suportes apropriados entre o cabeçote da caneta e a turbina pneumática. As esferas de menor diâmetro servem como separadores e substituem os separadores dos rolamentos convencionais, e através da baixa margem de folga entre as esferas intercaladas, quando a turbina está em funcionamento, é possível obter um deslizamento e sentido de rotação nas esferas maiores com o mínimo de ruídos possíveis. Outra característica inovadora apresentada pela caneta odontológica da presente patente de modelo de utilidade é a presença de um canal de escape para a saída de ar, excesso de lubrificantes e resíduos que possam se acumular no interior da caneta odontológica. Esse canal está presente na saída de ar da turbina pneumática e é acoplada a uma tubulação que tem como função levar o ar para um local remoto em relação ao local de trabalho. Como o som se propaga facilmente pelo ar, esse canal diminui significantemente o nível de ruído emitido pela caneta odontológica e transporta o ar e ruídos gerados pela turbina, esferas e demais componentes mecânicos, para fora do estabelecimento de trabalho. Some documents related to dental systems and turbines are known from the state of the art, among which we highlight document MU 8500878-8 which refers to a constructive arrangement introduced in a dental pen based on the use of a plumbing output of air and noise and a mechanical assembly that produces less vibration. The dental pen in question has in its internal structure a bearing assembly differentiated from the conventional assembly used in models known in the state of the art. This differential bearing assembly is formed by balls interspersed with other smaller diameter balls, which are supported by appropriate supports between the pen head and the air turbine. Smaller diameter balls serve as separators and replace conventional bearing separators, and through the low clearance between the interleaved balls, when the turbine is running, sliding and rotating direction can be achieved on the larger balls with minimal of possible noises. Another innovative feature presented by the dental pen of the present utility model patent is the presence of an exhaust vent, excess lubricants and debris that may accumulate inside the dental pen. This channel is present in the air outlet of the pneumatic turbine and is coupled to a piping that has the function of taking air to a remote location relative to the workplace. Because sound easily propagates through the air, this channel significantly decreases the noise level emitted by the dental pen and transports air and turbine-generated noise, spheres and other mechanical components out of the workplace.
[0008] As características descritas no documento acima para reduzir o ruído da caneta odontológica diferem totalmente do preconizado pela presente invenção.  [0008] The features described in the above document for reducing the noise of the dental pen differ totally from those advocated by the present invention.
[0009] Outro documento do estado da técnica que trata do assunto é o PI0405309-5 que descreve um sistema odontológico inteligente ergonómico e integrado para aplicação em atos cirúrgicos dento-bucais e protéticos, que tem a finalidade de eliminar fatores de invalidez profissional. É constituído de três módulos interdependentes, a saber: Módulo ergonómico de atuação manual direta nos atos cirúrgicos, dento-bucais e protéticos, que são motores de alta rotação e de baixa rotação, os quais são denominados por: 'canetas odontológicas ' , o qual é instalado, fixado no corpo da caneta odontológica, sendo dotado de sensores e comandos eletrónicos internos, submetidos ao controle externo, através de movimentos digitais dos profissionais; Módulo central de comando eletrónico e Módulo de válvulas eletropneumáticas ' on-off' eletro eletronicamente acionadas e controladas (pelo Módulo ergonómico) , ou mesmo uma única válvula eletropneumática proporcional acionada e controlada pelo Módulo ergonómico. Os Módulos são interligados através dos respectivos dispositivos e circuitos eletrónicos, elétricos e pneumáticos. Este sistema, assim como os outros sistemas, equipamentos, cadeiras odontológicas existentes, tem o ar comprimido, como fonte de energia cinética para acionamento da sua turbina de alta rotação, bem como sua turbina de baixa rotação. Tem esta Patente de Invenção, o intuito de solucionar os graves problemas aqui apontados, através da eliminação das fontes de LER 'Lesões por Esforços Repetitivos', ou melhor, através da eliminação das fontes de DORT 'Distúrbios Osteomoleculares Relacionados ao Trabalho', a saber, eliminando 'o pedal, o comando pedaleiro', que não mais existirá, sendo substituído pelo inovador Módulo ergonómico, instalado no corpo da caneta odontológica, o qual é acionado e controlado através de movimentos digitais pelos profissionais. Em função do avanço tecnológico, aperfeiçoamos este Pedido de Patente, salientando uma das inovações contidas no mesmo, quer seja: Controle remoto por frequência de rádio, em que todos os comandos, controles pneumáticos serão à viva voz (sintetizados), substituindo assim, não somente os camandos pedaleiros, como também, os comandos digitalizados . [0009] Another prior art document addressing the subject is PI0405309-5 which describes an integrated ergonomic intelligent dental system for application in dental-oral and prosthetic surgical acts, which is intended to eliminate occupational disability factors. It consists of three interdependent modules, namely: Ergonomic module of direct manual actuation in surgical, tooth-oral and prosthetic acts, which are high-speed and low-speed motors, which are called: 'dental pens', which It is installed, fixed in the body of the dental pen, being equipped with sensors and internal electronic commands, submitted to external control, through digital movements of professionals; Electronic central control module and Electronically driven and controlled electro-pneumatic on-off valve module (via the ergonomic module), or even a single proportional electropneumatic valve actuated and controlled by the ergonomic module. The modules are interconnected through their electronic, electrical and pneumatic devices and circuits. This system, like the others Existing dental systems, equipment, chairs have compressed air as the kinetic energy source to drive their high-speed turbine as well as their low-speed turbine. This Patent has the purpose of solving the serious problems pointed out herein by eliminating the sources of RSI 'Repetitive Strain Injury', or rather by eliminating the sources of DORT 'Osteomolecular Disorders Related to Work', namely , eliminating 'the pedal, the crankset', which will no longer exist, being replaced by the innovative Ergonomic Module, installed in the body of the dental pen, which is triggered and controlled by digital movements by professionals. Due to technological advancement, we have refined this Patent Application, highlighting one of the innovations contained therein, namely: Radio frequency remote control, where all commands, pneumatic controls will be live (synthesized), thus replacing not only the foot pedals, as well as the digitized commands.
[00010] De igual modo, as características descritas no sistema odontológico inteligente ergonómico e integrado diferem totalmente do conceito da presente invenção, uma vez que está baseado na substituição dos comandos convencionais dos equipamentos odontológicos por comandos remotos. Adicionalmente, esse sistema não suprime o ruído produzido pela turbina odontológica.  Likewise, the features described in the ergonomic and integrated intelligent dental system differ entirely from the concept of the present invention in that it is based on the replacement of conventional dental equipment controls with remote controls. Additionally, this system does not suppress noise produced by the dental turbine.

E não pretende identificar elementos fundamentais ou críticos, nem delinear o escopo de tais modalidades. Sua única finalidade é apresentar alguns conceitos das modalidades descritas na forma simplificada, como uma introdução à descrição mais detalhada que será apresentada adiante.
