G02B006/26
G02B006/42

US Classification:

385 18, 385 47

Abstract:

A fiber-attached optical device with in-plane micromachined mirrors includes a cover having at least one reflector formed on one side and a substrate having a plurality of micromachined optical mirrors formed substantially on a single plane on a side facing toward the mirrored side of the cover. The micromachined optical mirrors are controllable to reflect optical signals between a plurality of optical fiber segments via the at least one reflector. The plurality of optical fiber segments can be attached to either the cover or the substrate so as to form an integrated package including the substrate, the cover, and the plurality of optical fiber segments. The mirrors can be controlled to variably attenuate the optical signals.

International Classification:

A61B 1/32

US Classification:

600205, 600220

Abstract:

The embodiments disclosed herein relate to disposable speculums, and more particularly to disposable vaginal speculums having single-sided support and operating mechanisms. In an embodiment, a speculum includes an upper member having an upper blade and a hinge assembly; a lower member having a handle and a lower blade, wherein a combined smoke channel light guide directs light from a light source in the handle to a distal end of the lower blade for smoke removal; and a linear support member having a proximal end, a distal end, and an elongated body therebetween, the linear support member vertically moveable within a track positioned in the lower member.

Inventors:

Jeffrey Ralph Swift - Andover MA, US

Assignee:

OBP CORPORATION - Lawrence MA

International Classification:

A61B 1/32

US Classification:

600220, 600219

Abstract:

A speculum includes upper and lower members and a linear support member. The upper member includes an upper blade. The lower member includes a lower blade and a handle portion. The lower blade includes a support structure at a proximal end thereof which extends vertically on the right or left side of the lower blade, and a handle portion extending downwardly from the lower blade and defining a vertical track. The linear support member has a proximal end pivotally connected to the upper blade, a distal end, and an elongated body between the proximal and distal ends. The elongated body slidably engages the vertical track of the handle portion. The linear support member is formed with a hidden slot which slidably receives the support structure of the lower blade.
