The utility model relates to the technical field of medical instruments, in particular to a pressure steam cleaning device for a hard endoscope operating instrument, which comprises a machine body, a transparent sealing cover is slidably connected to the rear of the inner side of the machine body, and a push-pull steam nozzle rod is arranged on the right side of the rear inside the machine body. A pull-type telescopic flushing nozzle is fixedly connected to the rear of the right side of the top of the machine body, an exhaust fan is fixedly connected to the middle of the rear end face of the machine body, and an exhaust hole is formed between the rear of the interior of the machine body and the input end of the exhaust fan; through design cooperation of the push-pull type steam spray head rod and the cleaning roller, steam sprayed out of the push-pull type steam spray head rod can make uniform contact with an inner core clamp end tooth groove. And meanwhile, the steam conveying rod spray head is connected with the outer sleeve flushing hole, so that the device can perform high-temperature steam cleaning on the instrument outer sleeve limited in the outer sleeve clamping seat, and the purpose of mechanically cleaning the hard endoscope operation instrument is achieved.

This invention belongs to the field of image transmission fiber technology and discloses a bend-insensitive high-resolution image transmission fiber and its fabrication method. The image transmission fiber provided by this invention comprises several image transmission cores and a co-cladding layer between the image transmission cores; each image transmission core includes, from the inside out, a core layer, a recessed layer, an inner cladding layer, and a light-absorbing layer; the light-absorbing layer is quartz glass containing absorber ions and fluorine. The fabrication method of the image transmission fiber provided by this invention includes preparing a light-absorbing core rod, drawing the light-absorbing core rod to obtain a light-absorbing capillary rod, stacking several light-absorbing capillary rods in a pure quartz glass sleeve to obtain an image transmission fiber preform, and drawing the image transmission fiber preform to obtain a bend-insensitive high-resolution image transmission fiber. This invention can improve the imaging resolution of the image transmission fiber, and the fabrication method has the advantages of simple and convenient process and strong production stability.
