Sistema endoscópico de orientación espacial

Sistema endoscópico que comprende una lente tubular rígida con un canal para el paso de luz a través de fibra óptica, configurada para introducirse en una cavidad a través de un orificio o incisión cutánea y cuya función es captar y transmitir la imagen de la cavidad iluminada; una cámara conectada a un extremo de la lente tubular configurada para digitalizar la imagen obtenida a través de dicha lente tubular; una fuente de luz conectada también a la lente tubular por el extremo que se conecta a la cámara; un receptor de video conectado a la cámara a través del cual se recoge la señal proveniente de la misma; y una pantalla que permite visualizar la imagen saliente del receptor de video, estando el sistema caracterizado por que comprende además: - un sensor inercial que comprende al menos un acelerómetro de 3 ejes y un giroscopio de 2 ejes, estando el sensor inercial configurado para, a partir de los datos de aceleración angular obtenidos por el acelerómetro y de velocidad angular obtenidos por el giroscopio, proporcionar la orientación del sensor inercial a través de los ángulos de alabeo (rotación en el eje X) y cabeceo (rotación en el eje Y) que se corresponden con los ángulos de giro del endoscopio (cámara 10 + lente tubular 11) debido a los giros de muñeca del cirujano que está manejando el endoscopio, tal que dicho sensor inercial debe estar situado en la cámara (en su interior o en su superficie, a su entrada o salida) o en sus proximidades (a su entrada o salida), de forma que no interfiera al cirujano durante su utilización, y tal que el eje X del sensor inercial debe situarse de manera paralela al eje longitudinal de la lente tubular, el eje Y del sensor inercial de manera paralela al eje transversal de la lente tubular y el eje Z del sensor inercial de manera paralela a la vertical del endoscopio(cámara 10 +lente tubular 11); - un sistema informático que comprende un puerto de recepción de datos del sensor inercial conectado a dicho sensor inercial; una capturadora de video configurada para captarla señal de video de salida del receptor de video que recoge la señal proveniente de la cámara; una salida de video del mismo formato que el video de entrada recogido en la capturadora de video conectada a la pantalla y un puerto de conexión conectado a un dispositivo de interacción humana y que recoge los datos de dicho dispositivo; - un dispositivo de interacción humana configurado para interactuar con el software del sistema informático y comandar las funcionalidades pertinentes de dicho sistema informático.Solicitud: U201931231 (18.07.2019)Nº Pub. de Solicitud: ES1235420U (30.09.2019)Nº de Modelo de Utilidad: ES123542Y (23.12.2019

Estimation of surgeons' ergonomic dynamics with a structured light system during endoscopic surgery

Background: The purpose of this study was to use motion capture to collect body posture information during simulated endoscopic sinus surgery interventions performed by both specialists and residents in standing and sitting positions and to analyze that information with the validated Rapid Upper Limb Assessment (RULA) tool, which allows calculation of a risk index of musculoskeletal overload. Methods: Bilateral endoscopic sinus surgery was performed in 5 cadaver heads by 2 residents, and 4 practicing rhinologists. Musculoskeletal symptoms were evaluated before and after the dissection. Full?body postural data were collected with the help of Kinect and a .NET WPF (Windows Presentation Foundation) software application to record images of the surgical procedures, and then analyzed with the RULA tool to calculate a risk score indicative of the exposure of the individual surgeon to ergonomic risk factors associated with upper extremity musculoskeletal disorders. Results: All subjects reported physical discomfort after nasal endoscopic procedures. An overall similar RULA score was obtained by the residents and the practicing rhinologists. The RULA score was slightly lower for the sitting position than for the standing position, mostly due to a lower score in group B (neck, trunk, and leg); however, the RULA score for group A (arm and wrist analysis) was higher, denoting a higher risk for the upper back and arms. Conclusion: Significant musculoskeletal symptoms were reported after an endoscopic operation by both the resident and the practicing otolaryngologists. All surgeons obtained a high RULA score, meaning that urgent changes are required in the task.This project has been developed thanks to the Innovation Support Program "InnVal" of the Marques de Valdecilla Research Institute (IDIVAL

Evaluación subjetiva de las alteraciones del olfato y del gusto en pacientes con afectación leve por COVID-19 en España

International audienceBackground: Has been described the loss of smell and taste as onset symptoms in SARS-CoV-2. The objective of this study was to investigate the prevalence in Spain. Methods: Prospective study of COVID-19 confirmed patients through RT-PCR in Spain. Patients completed olfactory and gustatory questionnaires. Results: A total of 1043 patients with mild COVID-19 disease. The mean age was 39 ± 12 years. 826 patients (79.2%) described smell disorder, 662 (63.4%) as a total loss and 164 (15.7%) partial. 718 patients (68.8%) noticed some grade of taste dysfunction. There was a significant association between both disorders (p<.001). The olfactory dysfunction was the first symptom in 17.1%. The sQOD-NS scores were significantly lower in patients with a total loss compare to normosmic or hyposmic individuals (p =.001). Female were significantly more affected by olfactory and gustatory dysfunctions (p<.001). The early olfactory recover in 462 clinically cured patients was 315 (68.2%), during the first 4 weeks. Conclusion: The sudden onset smell and/or taste dysfunction should be considered highly suspicious for COVID-19 infection
