摘要： Disclosed is an exchangeable laser unit and an array thereof. The exchangeable laser unit includes cartridge receivers and housings having a uniform shape and uniform optical interfaces. The cartridge receiver adopts the optical interface including a tapered cavity and cylindrical cavity, so that a precise mechanical connection can be achieved between the output of laser of the cartridge receiver and the output of the optical fiber of the housing without professional tools, facilitating standardization of the output components of the laser elements of the cartridge receiver. In addition, the upper-lower guide rails and the upper-lower channels having certain of inclination degree can realize the precise positioning of the cartridge receiver and the housing. When replacing one laser element by a laser element that emits laser with a different wavelength, it is only necessary to replace the cartridge receiver inside the housing. That is, the replacement of laser elements having different wavelengths is converted to the replacement of cartridge receivers, which greatly reduces the difficulty for medical personnel to switch laser wavelengths, and improves the popularization of laser therapeutic instruments in the medical field. In the exchangeable laser array of the disclosure, the cartridge receiver inside the housing can be replaced by other cartridge receiver that emits laser with a different wavelength, and the plurality of housings can be connected with a plurality of wavelength switchers in the back to realize selective output of the wavelength.

摘要： Disclosed is a novel vascular optical fiber guidewire. The vascular optical fiber guidewire includes a metal axial wire and an optical fiber surrounding the metal axial wire. The optical fiber includes a core wire and a cladding layer covering the core wire. For above vascular optical fiber guidewire, in a part of the optical guidewire that is required to transmit light, a bending radius of the optical fiber around the metal axial wire is greater than a critical bending radius, and in a region of the optical fiber guidewire that is required to scatter light, the bending radius of the optical fiber around the metal axial wire is less than the critical bending radius. The present disclosure is capable of entering a blood vessel by a percutaneous puncture technique, guiding the optical fiber guidewire through a medical imaging device in a blood vessel, and performing side-illumination on the head.

摘要： A wavelength conversion device disclosed adopts a drive gear and driven gear as a main transmission structure, and disposes optical fiber plugs at a center of the driven gear. When a central shaft of the driven gear is unmovable, the rotation of the drive gear will drive the driven gear to rotate, and the rotation of driven gear will drive the optical fiber insertion rod to move up and down, thereby completing an insertion-extraction operation of the optical fiber insertion rod. When the central shaft of the driven gear is movable, i.e., when the optical fiber plugging rod is completely above the baseplate, the driven gear is locked with the optical fiber plug and thus they both cannot be rotated about their own axis, the driven gear will drive the fiber displacement plate to rotate along the drive gear under the action of the drive gear, thereby realizing the rotational translation of the optical fiber plugs, and reaching the switching wavelengths of laser at the optical fiber output interface. The wavelength conversion device is simple and easy for ordinary medical personnel to operate, thereby promoting the development of laser therapeutic instruments in the medical field.
