摘要:
Apparatus for safely and accurately positioning the fingertip of a physician (or technician) performing a biopsy procedure, e.g., to excise a core tissue samples of the male prostate or other internal organs, to avoid injury (e.g., a needle stick) from the sharpened distal end of a biopsy needle assembly. Such apparatus comprises an open tubular member defining an elongated passageway through which a biopsy needle assembly, when actuated, can be made to pass and to extend a predetermined distance along an external path in order to effect the core sampling of a biological mass of interest. The tubular housing supports a safety flange at its distal end, such flange having a flat surface adapted to be engaged by the fingertip of the physician prior to actuation of the biopsy needle assembly. Preferably, the engaged surface of the safety flange defines a physical fiducial adapted to be sensed by theuser's fingertip, such fiducial being located a predetermined safe distance from the external path traveled by the needle assembly, whereby the physician is assured that his or her fingertip is safely spaced from the needle assembly when actuated, and the distal end of the tubular housing is precisely positioned relative to a biological mass of interest.

A fishing line float and spool device is provided having a rounded, buoyant structure, and an arraignment that allows a length of fishing line to be independently supported from the water surface. The device comprises a first and second side having a perimeter flange and an inset channel therebetween for supporting the fishing line about the perimeter of the device. A plurality of notches is disposed through the flanges of each of the float sides. The fishing line attaches around the float and is extended therefrom, whereby the notches allow the line to be tied off such that when the line is struck by a fish the float flips over for notification purposes. The center of the float includes an aperture therethrough for assisting the user when tying off the fishing line, while also providing a support for an external hand crank reel or a lighted pole.

The present invention is a toy projectile launcher in the form of a role play accessory such as a belt. The belt assembly includes a strap, a launcher housing, and projectiles stored on the belt strap. The belt strap feeds through the launcher housing so that projectiles may be launched from the strap. In one embodiment the launcher is hand-held, and includes a handle which serves both as a means for holding the launcher during operation and as a power switch for the launcher. Projectiles may be discharged singly from the launcher or continuously in a rapid-fire mode.
