Abstract

The present invention is soft uretero-renoscope with hard sheath has the advantages of both hard uretero-renoscope and soft uretero-renoscope combined. After the soft uretero-renoscope with hard sheath is pushed through the ureteric orifice to the renal pelvis similar to operating one hard uretero-renoscope, the relevant members in the hard sheath are controlled to extend the soft uretero-renoscope from the hard sheath to the different parts of the renal calices, so as to reach the diagnosis and treatment aim. With combined advantages of both hard uretero-renoscope and soft uretero-renoscope, the soft uretero-renoscope with hard sheath has convenient operation and easy expanding.

Description

1. Technical field

[0001] It is used in the treatment of ureteral calculus and renal pelvis calculi in endourology, the diagnosis of renal pelvis tumors and ureteral tumors, and the hemostatic treatment of renal pelvis and ureter, etc. 2. Background technology

[0002] Rigid ureteroscope is easy to operate, but the front end cannot be bent, so it is impossible to treat renal pelvis and calyceal stones and diagnose tumors of renal pelvis and renal calyces through the ureter through a rigid ureteroscope. The front end of the flexible ureteroscope can be bent, and the direction can be adjusted after reaching the renal pelvis. Various diagnoses and treatments can be performed after entering each group of renal calyx. It is easy to damage the lens of flexible uretero-nephroscope, so it is difficult to popularize and apply in clinical work. The soft uretero-nephroscope with a hard sheath that we invented combines the advantages of both hard and soft ureteroscopes, and overcomes t...
