ANTECEDENTES DE LA INVENCIÓN BACKGROUND OF THE INVENTION
Los dispositivos endoscópicos son instrumentos en forma de tubo que contienen una luz y una óptica o cámara, que permite la visualización del interior de una cavidad u órgano corporal, introduciéndolo mediante un agujero natural o una pequeña incisión quirúrgica. Existen varios tipos de endoscopios, los cuales reciben el nombre de acuerdo con el área u órganos que exploran, por ejemplo, el artroscopio se utiliza para examinar directamente las articulaciones, el broncoscopio se emplea para examinar los pulmones, el laparoscopio se utiliza para examinar órganos abdominales como el apéndice y los ovarios y el cistoscopio es utilizado para visualizar el interior de la vejiga, entre otros. Endoscopic devices are tube-shaped instruments that contain a light and an optic or camera, which allows the visualization of the inside of a cavity or body organ, introducing it through a natural hole or a small surgical incision. There are several types of endoscopes, which are named according to the area or organs they explore, for example, the arthroscope is used to directly examine the joints, the bronchoscope is used to examine the lungs, the laparoscope is used to examine organs Abdominals such as the appendix and the ovaries and the cystoscope are used to visualize the inside of the bladder, among others.
El procedimiento diagnóstico que utiliza cualquier tipo de endoscopio se conoce como endoscopia. La endoscopia es una técnica diagnóstica y terapéutica utilizada sobre todo en medicina, que consiste en la introducción de una
cámara o lente dentro de un tubo o endoscopio a través de un orificio natural, una incisión quirúrgica o una lesión para la visualización de un órgano o cavidad corporal. The diagnostic procedure that uses any type of endoscope is known as endoscopy. Endoscopy is a diagnostic and therapeutic technique used primarily in medicine, which involves the introduction of a camera or lens inside a tube or endoscope through a natural hole, a surgical incision or a lesion for the visualization of an organ or body cavity.
Un endoscopio ordinario se compone de un tubo o cable semiflexible por donde se introduce una luz o lámpara, que provee iluminación para la visión en espacios u orificios, o en su caso una cámara para la captura de imágenes o video. El tubo o cable semiflexible se conecta a un ordenador o dispositivo portátil donde a través de una pantalla se genera la imagen o video capturado para su documentación y procesamiento. Actualmente, en los procedimientos médicos generalmente se utilizan endoscopios con cámaras o videoendoscopios para capturar imagen o video durante las exploraciones. El problema con los endoscopios convencionales consiste en que son dispositivos de gran tamaño que utilizan cables para conectar la cámara al ordenador o dispositivo portátil que genera las imágenes o videos, además estos dispositivos se colocan en gavetas móviles para desplazarlos durante su utilización, por lo tanto, dichos dispositivos se vuelven estorbosos y dificultan las labores médicas ya que reducen el espacio donde se trata al paciente. Aunado a esta situación, los altos costos de los endoscopios los vuelven casi inaccesibles para la mayoría de los médicos y terapeutas. Al respecto, la presente invención propone una solución funcional para el procedimiento de endoscopia, a través de un dispositivo endoscópico que consiste en un dispositivo miniaturizado, portátil, inalámbrico y que no requiere cables para su alimentación, conectado a un transmisor que envía imágenes y videos utilizando radiofrecuencia a un ordenador portátil o de escritorio para su procesamiento. Está diseñada para mejorar el desempeño de un endoscopio convencional de varias maneras. Por ejemplo, utiliza sensores de video miniaturizados de última generación así como dispositivos modernos de comunicación (USB, Wi-Fi o Bluetooth) para interactuar con una computadora portátil o de escritorio y transmitir imagen y video. Asimismo, es un dispositivo desechable y de bajo costo de producción. Estas características le permiten al usuario tener un dispositivo portable y desechable de inspección incluso para trabajo de campo fuera del cuarto de operación o de las instalaciones médicas;
además, su bajo costo lo hace accesible al consumidor dentro del mercado de productos médicos. An ordinary endoscope consists of a semi-flexible tube or cable through which a light or lamp is introduced, which provides illumination for vision in spaces or holes, or where appropriate a camera for capturing images or video. The semi-flexible tube or cable is connected to a computer or portable device where the captured image or video is generated through a screen for documentation and processing. Currently, medical procedures generally use endoscopes with cameras or video endoscopes to capture image or video during scans. The problem with conventional endoscopes is that they are large devices that use cables to connect the camera to the computer or portable device that generates the images or videos, in addition these devices are placed in mobile drawers to move them during use, therefore , said devices become cumbersome and make medical work difficult since they reduce the space where the patient is treated. In addition to this situation, the high costs of endoscopes make them almost inaccessible to most doctors and therapists. In this regard, the present invention proposes a functional solution for the endoscopy procedure, through an endoscopic device consisting of a miniaturized, portable, wireless device that does not require cables for power, connected to a transmitter that sends images and videos using radio frequency to a laptop or desktop for processing. It is designed to improve the performance of a conventional endoscope in several ways. For example, it uses state-of-the-art miniaturized video sensors as well as modern communication devices (USB, Wi-Fi or Bluetooth) to interact with a laptop or desktop computer and transmit image and video. It is also a disposable device with low production cost. These features allow the user to have a portable and disposable inspection device even for field work outside the operating room or medical facilities; In addition, its low cost makes it accessible to the consumer within the medical products market.

Another US document, 6,033,360, refers to a portable endoscope that is composed of an apparatus that functions as a source of illumination attached to an endoscopic device, and its main feature is that it is designed so that the heat radiated by the lamps of traditional endoscopes does not affect endoscopic operation.
Un endoscopio, en particular un artroscopio, es referenciado en el documento estadunidense 5,184,602, y consiste en un asta cilindrica que contiene ópticas y fibras ópticas, diseñado para aumentar el ángulo de visión a través de la rotación de las ópticas. An endoscope, in particular an arthroscope, is referenced in US 5,184,602, and consists of a cylindrical pole containing optical and optical fibers, designed to increase the viewing angle through the rotation of the optics.
Por su parte, el documento internacional PCT/KR2009/004424 describe una cápsula endoscópica inalámbrica con capacidad de comunicación de ultra banda ancha (UWB) y un método de transmisión y recepción de imágenes. No obstante, esta invención se trata de una cápsula que debe ser introducida al cuerpo del paciente por la boca y viaja por el aparato digestivo, donde capta las imágenes fotografiando el estado de los órganos; en cambio, la presente invención describe un dispositivo endoscópico inalámbrico cuya forma es similar a la de un bolígrafo, para examinar articulaciones y cavidades del cuerpo del paciente. For its part, the international document PCT / KR2009 / 004424 describes a wireless endoscopic capsule with ultra-broadband communication (UWB) capability and an image transmission and reception method. However, this invention is a capsule that must be introduced to the patient's body by mouth and travels through the digestive system, where it captures the images by photographing the state of the organs; instead, the present invention describes a wireless endoscopic device whose shape is similar to that of a pen, to examine joints and cavities of the patient's body.
De las consideraciones anteriores, se deduce que ninguno de estos dispositivos es similar a la presente invención y no ofrecen las mismas ventajas en cuanto a funcionalidad.
