Ureter guide sheath

Abstract

The invention discloses a ureter guide sheath, and belongs to the technical field of medical instruments. The ureter guide sheath comprises a sheath pipe base, a sheath pipe is connected with one endof the sheath pipe base, the other end of the sheath pipe base is embedded into a center hole of an expansion pipe connector through an expansion pipe, a clamping hook is arranged on the expansion pipe connector, a clamping table matched with the clamping hook is arranged at one end, close to the expansion pipe connector, of the sheath pipe base, a hand shank is arranged at one end, far away fromthe expansion pipe connector, of the sheath pipe base through a sleeve in a sleeving manner, the hand shank is perpendicular to the sleeve and comprises a pipeline and a handle, the handle is fixedlyarranged at the bottom of the pipeline, the sheath pipe base is communicated with the pipeline through a second through hole, a boss is arranged between the clamping table on the sheath pipe base andthe second through hole, the boss and the second through hole are positioned on the same side, a semicircular open groove matched with the boss is formed in the upper edge of the sleeve, and the handshank can rotate clockwise by 180 degrees along a center axis of the sheath pipe base under the limiting actions of the boss and the semicircular open groove. The ureter guide sheath is conveniently operated by a doctor, and smooth implementation of ureteroscope surgery can be ensured.

Description

technical field [0001] The invention relates to the technical field of medical devices, and relates to a ureteral guide sheath, in particular to a ureteral guide sheath with a base structure provided with a handle, and a ureteral guide sheath capable of rotating 180 degrees clockwise along the central axis of the sheath tube for suction and irrigation. Background technique [0002] With the popularization and application of ureteroscopes in our country, urologists are increasingly using ureteroscopes to solve various ureteral diseases encountered clinically, and the treatment methods and means are also constantly improved and perfected. However, ureteral stenosis and ureteral lumen stenosis lead to ureteral injury, surgical failure, and surgical plan changes, which bring difficulties to follow-up treatment and have always troubled urologists who operate ureteroscopes. In order to solve this problem, a ureteral introducer sheath tapered dilation tube / sheath assembly was later...

AI Technical Summary

Problems solved by technology

However, the structure of the existing ureteral guide sheath is not perfect, especially the base of the ureteral guide sheath has no handle, and there is no suction and flushing structure, which is inconvenient for doctors to operate and the smooth progress of ureteroscopic surgery
