Embodiment Construction

[0017] Let part C and part B of the hard sheath be in the operating state of the hard mirror and fix them completely so that parts C and B cannot slide. At this time, the front end of the detachable soft mirror is just flush with the front end of the hard mirror sheath. , can be completely operated according to the hard ureteroscope, and enter the renal pelvis; after that, by controlling the sliding of parts C and B of the hard sheath part, the detachable soft mirror can extend out of the front end of the hard sheath part to varying degrees, and by controlling the z of the soft mirror part The channel bends the front end of the flexible mirror to different degrees, and rotating parts C and B of the hard sheath can make the front end of the detachable flexible mirror reach or enter different renal calices or renal pelvis parts, so as to achieve the purpose of diagnosis and treatment.

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...
