The importance of the introduction to the scientific initiation in the construction, characterization and sensing of surgical instruments and biomedical equipment

Scientific initiation refers to an activity that initiates the undergraduate student in the production of scientific knowledge. However, Brazilian higher education was set up focused on professional education, with no space for the humanistic and scientific training of the student, which is reflected this day in the country since there are few institutions that associate teaching and research [1]. From this perspective, it is essential to promote scientific initiation, especially when it is done in an interdisciplinary way, as this model is not widespread in universities. The development of projects involving the making, characterization, and sensing of surgical instruments and biomedical equipment, promotes a deeper immersion between the exact and health sciences, improving the teaching-learning process, the development of devices, and the success rate in their use. As with video laryngoscopes, video laryngoscopy was especially preferred during the SARS-COV-2 pandemic, due to the increased probability of first-pass success in patients with difficult airways [2]. It was observed that the amount of force exerted during laryngoscopy is the main determinant for the mechanical stimulation of the supraglottic region and stretch receptors present in the respiratory tract [3]. Thus, the use of different types of laryngoscope blades can help to reduce these responses, since excessive forces can stimulate to lead to pathological responses of the cardiovascular systems; changes in hemodynamic parameters, and local effects, such as edema, tooth, and soft tissue injury [4]. This paper presents a case study of the experience of a medical student in the characterization and sense of biomedical equipment: an anatomical video laryngoscope sensorized on the blade and printed in ABS. Therefore, this study reported the importance of scientific research within scientific initiation in the making, characterization, and sensing of surgical instruments and biomedical equipment, in particular, an anatomic video laryngoscope in ABS.
