Ralph C. Tillinghast - Hardwick NJ, US

Assignee:

The United States of America as Represented by the Secretary of the Army - Washington DC

International Classification:

F21V 23/00

US Classification:

42132, 362 84

Abstract:

An improved aiming post light configuration wherein a luminescent material in conjunction with an optical taper or other magnification structure is positioned within the body of the aiming post along with a recharge circuit which recharges the luminescent material periodically or when light output from the luminescent material falls below a predetermined threshold. Advantageously, the entire configuration may be integral to the aiming post itself.

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.

International Classification:

A61B001/005

US Classification:

600/146000

Abstract:

An endoscope for remotely viewing and testing relatively inaccessible regions of structures that are under stress when used, the endoscope having a mechanically-articulated articulating distal end. The endoscope includes an elongated shaft having a proximal end and a distal working end. There is a working channel located within the shaft and open at both ends. A remote material stress-testing probe is located at least partially within the working channel, and is adapted to contact the region to be tested. There is at least one light guide in the shaft for carrying light introduced into the proximal end to a remote viewing area proximate the distal end. The endoscope further includes a user-operable shaft tip steering mechanism for articulating the distal end of the shaft. The tip steering mechanism includes at least two rotatable drums, at least a pair of wires coupled to the drums, and also coupled to the tool's articulating distal end, for translating drum rotation into distal end articulation, a mechanical joystick moveable translationally and through 360 degrees rotationally, and a mechanism coupling the joystick to the drums, that mechanically translates motion of the joystick into rotation of the drums, wherein motion of the joystick in one plane causes rotation of only a first drum, and motion of the joystick in a perpendicular plane causes rotation of only a second drum, and movements of the joystick not wholly within these two planes causes rotation of both the first and second drums.
