Filed:

Sep 16, 2005

Appl. No.:

11/229321

Inventors:

Assignee:

Optim, Inc. - Sturbridge MA

International Classification:

A61B 1/06

US Classification:

362574

Abstract:

The present invention is directed to methods of mounting a light source, such as, for example a high-efficiency, high-power solid state light source (e. g. , a LED) within a handle of an endoscope. One of the methods of the present invention includes removing a portion of a package surrounding the light source to expose a light source chip, positioning the exposed light source adjacent to a chassis within the handle and in contact with an end of a light guide bundle, translating the light source with the exposed light source chip about the end of the light guide while measuring light output from an illumination (i. e. , distal) end of the light guide bundle with a photodetector, and securing the exposed light source to the chassis at a position in which maximum light output is measured.

F21V 5/00

US Classification:

362574, 362554, 362555

Abstract:

A compact, high-efficiency, high-power, solid state light source, comprising a high-power solid state light-emitting device, a light guide having a proximal light-receiving end proximate the light-emitting device and a distal light-transmitting end spaced farther from the light-emitting device, and a mechanical light guide fixing device coupled to the light guide near its proximal end, to hold the proximal end of the light guide in position near the light-emitting device.

International Classification:

F21V 7/04

US Classification:

362558, 362555, 385121, 385901

Abstract:

Illumination devices include a light source including a substantially planar light-emitting surface and an optical rod or optical taper disposed proximate to the substantially planar light-emitting surface to optically couple the optical rod and the substantially planar light-emitting surface.

International Classification:

A61B001/00

US Classification:

600/146000

Abstract:

A mechanism for articulating the distal end of an elongated tool through movement of drums, in which wires coupled to the drums connect the mechanism to the distal end of the tool that is being articulated. The mechanism comprises a joystick coupled to a rotatable shaft that is coupled to one of the drums. When the joystick is moved in one direction, the shaft is rotated, thereby rotating the drum and causing articulation in one plane. There is an arc arm rotatable by movement of the joystick. The arc arm rotates about an axis that is transverse to the shaft rotational axis. Rotation of the arc arm is accomplished by movement of the joystick in a plane that is transverse to the plane in which the joystick is moved to cause rotation of the first rotatable shaft. A gear system translates rotation of the arc arm to rotation of the second drum, to cause articulation in an articulation plane that is perpendicular to the articulation plane caused by rotation of the first drum. The result is an intuitive mechanical connection between the joystick and the articulating head that is simple to use and provides direct mechanical feedback from the articulating head to the user's hand.
