Abstract

Appareil de fixation d'endoscope réglable, se rapportant au domaine technique des dispositifs médicaux, et comprenant un support de liaison, un trou de limitation étant disposé sur le support de liaison; un tube d'un endoscope (9) passe à travers le trou de limitation et s'étend sous le support de liaison; un limiteur de profondeur (2) est disposé sur le tube de l'endoscope (9), le limiteur de profondeur (2) étant situé au-dessus du trou de limitation, et le limiteur de profondeur (2) limitant la position de l'endoscope (9). L'appareil de fixation limite la hauteur de l'endoscope (9) au moyen d'une coopération entre le limiteur de profondeur (2) et un siège mobile (1). Pendant une opération chirurgicale, il n'est pas nécessaire de stabiliser constamment l'endoscope (9); de plus, au moyen de la fourniture du siège mobile (1) et d'un bras de liaison (4), le bras de liaison (4) peut être commodément relié et fixé à un bras fixe ou à un écarteur de vertèbre cervicale, et peut être ajusté selon un site chirurgical.
