摘要： The present application relates to a shape memory alloy hypotube as well as use thereof in a blood vessel optical fiber guide wire. The hypotube comprises several spiral coils. This hypotube is made from a shape memory alloy such that its diameter varies over temperature. Thus, it can closely wrap an axial fiber disposed therein. Through phase change properties and shape memory properties of the memory alloy, the inner diameter of the hypotube changes over temperature. The hypotube produces two functions: making a wrapping expand and tight binding fixed. The shape memory alloy hypotube can improve the strength and safety of optical fiber guide wire. The hypotube can easily enter the blood vessel of human body. Further, the conventional winding process can be simplified.

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.
