Speculum for examination of cavity

Claim 2

A speculum for the examination of a body cavity or the like, comprising a first angle piece with both angle legs being formed with grooves, but one angle leg at least partially being narrower than the other angle leg, a second similar angle piece and coupling means near the angle point of each of said angle pieces for connecting pivotally and locking said first and second angle pieces in selected positions wherein either the narrower legs or the wider legs of the respective angle pieces are in substantially parallel relation.

Claim 3

A speculum according to claim 1, Characterized in that the grooved angle legs form with each other angles of approximately 270*, and are coupled together in a manner such that the respective sUpplementary 90*, angles thereof do not overlap.

Claim 4

A speculum according to the claim 1, characterized in that the coupling element of one of two assembled angle pieces is on the bisector or its extension adjacent the angle point and comprises pins and the coupling element of said second angle piece comprises oblong holes located with the center on the bisector or its extension adjacent the angle point on the second angle piece, and that the angle pieces include locking means for preventing pivotal motion at least in one direction when the pins reside in one end of the oblong holes, and with release means for rendering possible free pivotal motion of the angle pieces when the pins reside in the other ends of the oblong holes.

Claim 5

A speculum according to claim 3, characterized in that the locking means comprise projections mounted on one angle piece at some distance from the angle point adjacent the edges of the grooves, and substantially arcuate and sawtooth-shaped paths mounted on the second angle piece on both sides of the angle point.

Claim 6

A speculum according to claim 3, characterized in that the release means are smooth paths mounted on the second angle piece adjacent the sawtooth-shaped paths.

Claim 7

A speculum according to claim 3, characterized in that the oblong holes, for effecting snapping action at the displacement of the pins in the holes, are given smaller width at the center than at the ends, and that the holes, for effecting springing action, are extended in both directions by narrow slots.

Claim 8

A speculum according to claim 1, characterized in that the angle pieces are unitary bodies of synthetic resinous material.

Claim 9

A speculum according to claim 1, further including a detachable handle constituting a container internally-shaped to be engaged on one of the legs of the angle pieces for collecting secretion or the like.

Claim 10

A speculum according to claim 8, characterized in that said container is provided in its interior with ledges against which the edges of the grooves in the angle pieces are brought to abut when the handle is being applied.
