APPARATUS FOR OBSERVATIONS, PHOTOGRAPHS AND INTERVENTIONS IN THE POST-RHINAL-PHARYNGEAL REGIONS

摘要

The invention relates to an apparatus for use in examinations as operations in regions of the postrhinopharyngeal cavity. The apparatus consists of a mirror insertable into the cavity and having a frame and pivots rotatable in bearings of a supporting device ended by a ring. A device with an adjustment knob is connected by a crank to the mirror. A tubular speculum may receive this assembly and be rotatable on a fixed support at an end with a ring having a rotating joint and means for displacing a composite lens or operational microscope on the support relative to the mirror. The apparatus is equipped for blowing warm air on the mirror to prevent it from misting. A device usable with this instrument has a curved and cutout plate which covers from behind and holds back the uvula and the soft palate. This device has a variable length and carries via a hinge another curved plate with a cutout which bears on the nasal fossae, clinging to the patient's face.
