Abstract: A handheld surgical endoscope has a disposable, single-use portion that includes a fluid hub, cannula, distal tip and an integrated needle and a re-usable portion that includes a handle and display module. The distal tip includes LED illumination and an imaging module that feeds live video to the display module that is rotatable to allow viewing by the operator and others. The single-use and re-usable portions mate and un-mate with each other via physically separated mechanical and electrical connectors. The needle is actuatable to allow for both recessed and extended positions. The needle delivers liquid from a attached syringe that can be attached to the handle to move therewith or only connected to the endoscope by a flexible conduit. The surgical endoscope is configured for operation by a single clinician in many procedures.

Abstract: A handheld surgical endoscope has a disposable, single-use portion that includes a and a re-usable portion that includes a handle and display module. The distal tip includes LED illumination and an imaging module that feeds live video to the display module. The imaging module includes a lens system of no more than two lenses and provides the imaging module with a field of view greater than 120 degrees, preferably 130 degrees or more, and most preferably 140 degrees or more. LED illumination is provided by plural LED arranged symmetrically around an optical axis to provide a field of illumination that substantially coincides with the field of view of an imaging module. An image brightness balance arrangement selectively varies the illumination provided by different LEDs to reduce brightness differences between different areas of the displayed images.

Abstract: A handheld endoscope has a disposable, single-use portion that includes a fluid hub, cannula and distal tip and a re-usable portion that includes a handle and display module. The electrical connection between the single-use and reusable portions is distally spaced from their mechanical connection and from the fluid hub. The distal tip includes LED illumination and an imaging module that feeds live video to the display module that is rotatable to allow viewing by the operator and others. The cannula and fluid hub are rotatable relative to the handle and includes separate lumens for fluid flow and an electrical cable. The fit resists rotation to maintain the relative positions of the cannula and handle until the application of a torque threshold. The single-use and re-usable portions mate and un-mate with each other via the physically separated mechanical and electrical connectors. Extruded cannula and molded distal tip parts can be separately formed which aids in manufacturing and assembly.

Abstract: The present invention relates to a method of word screen formation by laser light projection and the structure of word formation by laser light projection, and in particular, relates to a plurality of laser production devices arranged in a single column and by rapid reciprocating action of the devices to project multiple columns of light track and form word arrays.

Abstract: A camera with laser view framing function includes a housing that is provided with a laser generated near a lens of the camera. The laser generator has a beam emitting hole that is oriented substantially the same direction as the lens. The housing is formed with a window on a wall that corresponds to the beam emitting hole. A shade having a frame profile through hole is insertably provided in the window. A switch key for actuating the laser generating is projectingly provided on the housing. When the switch key is pressed, the laser generator is actuated to emit a laser beam, which passes through the frame profile through hole of the shade to form a profile light frame framing an area of which a user is taking a picture.

Abstract: A laser level includes a transparent container, a buoy with a built-in laser component, and a support frame. The center of gravity of the buoy is always at the center of the buoy. One end of the buoy emits horizontal laser beams, the other end thereof emitting vertical laser beams. Two spindles respectively extend from both sides of the center of the buoy such that the spindles are perpendicular to the body of the buoy. The distance between the distal ends of the spindles is equivalent to the internal width of the container. Brackets are disposed on the inner wall of the container at a suitable height. The buoy is mounted on the brackets by means of the spindles to achieve balance and stability. The container is supported on the support frame so that it can be placed on surfaces of any uncertain plane.
