Speculum lens structure

In combination, a pair of contacting members and an operating handle for movably mounting the contacting members relative to each other, each contacting member including means cooperating with the operating handle to mount the contacting member on the operating handle, means projecting away from the mounting means to contact a meatus, means for mounting a light source remote from the meatus, means for transmitting light along the contacting member away from the mounting means, and a lens formed on the contacting member for directing the transmitted light in a desired manner into the meatus, the lens being formed at the end of the transmitting means remote from the source, and including a surface for directing light into the meatus, the surface causing focussing of the light as it passes through the surface into the meatus.

A medical instrument, comprising a pair of contacting members and an operating handle for movably mounting the contacting members relative to each other, each contacting member including means cooperating with the operating handle to mount the contacting member on the operating handle, means projecting away from the mounting means to contact a meatus, means for mounting a light source remote from the meatus, means for transmitting light along the contacting member away from the mounting means, and a lens formed on the contacting member for directing the transmitted light in a desired manner into the meatus, the lens being formed at the end of the transmitting means remote from the source, and including a surface for directing light into the meatus, the surface causing diffusion or spreading of the light as it passes through the surface into the meatus.

A medical instrument including a pair of contacting members and an operating handle for movably mounting the contacting members relative to each other, each contacting member including a portion for attachment to the operating handle and a portion for insertion into a meatus, the portion for insertion having a side facing away from the wall of the meatus, a side for contacting the wall of the meatus and an edge separating the two sides and extending around a portion of the perimeter of the contacting member, means for mounting a light source remote from the meatus, a lens formed on the side facing away from the wall of the meatus, and means for transmitting light along the contacting member to the lens, the means for mounting the light source including means for attaching the light source to the contacting member on the side facing away from the meatus wall adjacent the portion for attachment to the speculum.

In combination, a contacting member and an operating handle for supporting and manipulating the contacting member in a meatus, the operating handle including a shaft provided with a longitudinally extending slot opening in an end and a side wall thereof, and an enlarged longitudinally extending opening in the interior thereof and opening in said end, the slot intersecting the opening, the contacting member including a portion for attachment to the shaft, the attachment portion including a first part engageable in the slot and a second portion engageable in the enlarged portion.

In combination, a contacting member and an operating handle for supporting and manipulating the contacting member in a meatus, the operating handle including a shaft provided with a longitudinally extending keyhole-shaped transverse section opening intersecting a side wall of the shaft, and the contacting member including a portion for attachment to the shaft, the attachment portion including a keyhole-shaped projection for sliding insertion into the opening.
