摘要：
The utility model relates to medical apparatus, and in particular to a rigid/flexible adjustable ureteroscope which includes a body, an operation shank and a rigid/flexible adjustment support rod. A rigidity adjustment key controls the rigid/flexible adjustment support rod to be movable freely in the body so that the rigid/flexible adjustment support rod channel. Movement of the rigid/flexible adjustment support rod makes a part of the endoscope becomes rigid so as to have adequate rigidity to overcome resistance, avoiding the needs of hard sheath while entering a uterer. A front part of the endoscope may become from rigid to flexible by movement of the support rod, and the flexible front part may vary in length to accomplish the operation flexibly. The support rod is able to be movable or be drawn out from a support rod channel to serve the support rod channel as a work channel. By adjustment of sizes, a rigid/flexible adjustment fibronephorscope is provided, and alternatively, a rigid/flexible adjustment fiber urethra cystoscope is provided. Compared with the prior art, the utility model overcomes defects of various urethra cystoscopes, raises surgical efficacy and economic merits, avoids hurt to tissues, and reduces apparatus acquisition cost.
