Flexible ureteroscope ruler, manufacturing method thereof and purpose thereof

Abstract

The invention discloses a flexible ureteroscope ruler, a manufacturing method thereof and a purpose thereof. The flexible ureteroscope ruler comprises at least a set of transparent thin sheets. Ureteroscope sheath superimposed images and flexible ureteroscope body working-area synthesis images which are connected together are arranged on the set of transparent thin sheets according to different shooting ratios respectively. The ureteroscope sheath superimposed images and the flexible ureteroscope body working-area synthesis images are obtained in the mode that a ureteroscope sheath of a flexible ureteroscope serves as the arrangement standard and all images shot when a flexible ureteroscope body of the flexible ureteroscope is bent towards the same sides in the different-extending-length states are synthesized. The flexible ureteroscope ruler is used for simulating the area where the flexible ureteroscope can reach in the kidney pelvis and the kidney calyx of the kidney and pre-judging the feasibility of a flexible ureteroscope operation, and has the advantages of being noninvasive, simple and visual; the success rate of flexible ureteroscope operation performing is increased, and use of flexible ureteroscope resources is optimized.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a flexible ureteroscope scale and its production method and application, which are used to judge the feasibility of kidney stone ureteroscope surgery before surgery. Background technique [0002] Kidney stones are one of the common diseases in urology. Currently, the main surgical treatment methods for kidney stones include extracorporeal shock wave lithotripsy (ESWL), percutaneous nephrolithotripsy (PNL) and ureteroscopic lithotripsy (URS). Flexible ureteroscope is an important tool for ureteroscopic lithotripsy. It uses the natural cavity of the human body to perform lithotripsy with the help of holmium laser and other tools. It has the advantages of small trauma, low bleeding risk, and fast postoperative recovery. It is mainly suitable for: ①Ureteral calculi, especially upper ureteral calculi; ②Renal pelvis and calyceal calculi below 2 cm; ③It is not suitable for ESWL...

AI Technical Summary

Problems solved by technology

However, in clinical work, the application of flexible ureteroscope lithotripsy is limited due to the low success rate of the operation, especially for calculi in the lower calices of the kidney, which often cannot be performed due to factors such as the characteristics of different brands of flexible lenses, the anatomical structure of the renal pelvis and calyces, and other factors. It can be completely removed or cannot be removed, and the cost of using soft mirrors is high, which causes a great waste of medical resources
