Abstract
Abstract 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.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
247 words
An endoscope system comprising: a stationary support; a tubular housing defining an optic axis and having a narrow end distal from said support and a broad end adjacent said support; a mirror assembly pivotal about a mirror axis transverse to said optic axis and including a planar mirror having a reflective face, a frame surrounding said mirror and formed with an annular chamber and a plurality of orifices extending from said chamber and opening toward said face of said mirror, and at least one hollow pivot gudgeon journaled in said narrow end of said housing on said mirror axis and having a hollow interior communicating with said chamber, said housing including a pair of hollow arms each having one end carrying a respective gudgeon, and each having another end attached to said means for rotation of said housing and said assembly about said optic axis, said means for feeding air being connected to said other ends of said arms; means for feeding air through said gudgeon into said chamber and thence through said orifices over said face of said mirror for demisting same; means on said support for rotation of said housing and said mirror assembly about said optic axis; means on said broad end of said housing including a link extending to said mirror assembly for pivoting said assembly about said mirror axis; and means on said support including a mounting plate adapted to carry an observation apparatus for displacing said plate along said optic axis.
Claim 2
Dependent Claim
247 words
An endoscope system comprising: a stationary support; a tubular housing defining an optic axis and having a narrow end distal from said support and a broad end adjacent said support; a mirror assembly pivotal about a mirror axis transverse to said optic axis and including a planar mirror having a reflective face, a frame surrounding said mirror and formed with an annular chamber and a plurality of orifices extending from said chamber and opening toward said face of said mirror, and at least one hollow pivot gudgeon journaled in said narrow end of said housing on said mirror axis and having a hollow interior communicating with said chamber, said housing including a pair of hollow arms each having one end carrying a respective gudgeon, and each having another end attached to said means for rotation of said housing and said assembly about said optic axis, said means for feeding air being connected to said other ends of said arms; means for feeding air through said gudgeon into said chamber and thence through said orifices over said face of said mirror for demisting same; means on said support for rotation of said housing and said mirror assembly about said optic axis; means on said broad end of said housing including a link extending to said mirror assembly for pivoting said assembly about said mirror axis; and means on said support including a mounting plate adapted to carry an observation apparatus for displacing said plate along said optic axis.
Claim 3
Dependent Claim
247 words

Claim 5
Dependent Claim
88 words
The endoscope system defined in claim 1 wherein said means for rotation of said housing and said assembly includes a first ring secured to said support, a second ring secured to said other ends of said arms and rotatable relative to said first ring, said rings being formed at their interface with an annular chamber opening in said second ring into said other ends of said arms, said means for demisting including a connection through said first ring with said chamber at said interface for feeding air thereto.
Claim 6
Dependent Claim
73 words
The endoscope system defined in claim 1 wherein said means for rotating said mirror assembly about said mirror axis includes a pivot on said housing, a knob carried on said pivot outside said housing, an eccentric crank carried on said pivot inside said housing, and a pivot pin on said frame offset from said mirror axis, said link having one end connected to said crank and another end connected to said pivot pin.
Claim 7
Dependent Claim
