    摘要： A needle device according to the invention comprises a hollow shaft, an elongated insert and an operating means. The hollow shaft has a first distal end portion with a bevel, the elongated insert has a second distal end portion and is movably arranged within the hollow shaft, and the operating means is shiftable between a first condition and a second condition. Furthermore, the operating means is interconnected with the elongated insert, so that the second distal end portion is located within the hollow shaft and proximally to the bevel, when the operating means is in the first condition, and that the second distal end portion is located outside the hollow shaft and distally to the bevel, when the operating means is in the second condition.

    摘要： The present invention relates to an optical probe (1) suitable for miniature applications. An example application is a fibre-based confocal miniaturized microscope. The optical probe comprises a coil-based actuation system (9, 10) comprising drive coils (9) capable of displacing the distal end (3) of an optical guide (2) housed (4) by the optical probe. The probe makes use of a feedback loop which alternate between driving the displacement of the optical guide by driving a current through the drive coils and switching off the current through the drive coils, and while the drive current being switched off, measure the speed of the distal end of the optical guide. The measured speed is compared to the set-point speed, and if a difference is detected, the drive current is adjusted to eliminate, or at least bring down, this difference.

    摘要： The present invention relates to an optical scanning probe assembly for microscopic guide optic scanning and inspection of tissues suitable for application in, e.g. in vivo medical inspection and biopsy. The assembly comprises an outer housing (3) comprising: i) a spring element for a scanning motor, the spring element formed as a hollow tube (5) adapted to receive an optical guide, the hollow tube having mechanical stiffness larger than the optical guide to be received, ii) a lens system (7) and iii) N means for deflecting (6) the distal end of the hollow tube in directions transverse to the longitudinal extension of the hollow tube, so as to form an optical scan pattern. The optical assembly is particularly advantageous as it increases the freedom to optimize the optical and mechanical performance of the system which is defined respectively by the optical guide and by the hollow tube. The probe can be used in resonant and non-resonant scanning modes.

    摘要： A fiber scanning system is provided comprising a housing (102) with a fiber (13), the fiber (13) comprising a fixed part and a free end, the fixed part being attached to a bottom of the housing (102) and the fiber (13) extending parallel to the wall of the housing (102). At least one electrical coil (12) is attached to the wall at a position in between the fixed part and the free end of the fiber (13), a winding of the electrical coil (12) being in a plane parallel to the fiber (13). A magnet (11) is attached to the fiber (13), such that the electrical coil (12) may induce a force on the magnet (11). The magnet (11) is attached to the fiber (13) at a position just before or after the electrical coil (12), a width of the magnet (11) being such that the magnet (11) extends over the electrical coil (12).
