Ureteroscope

Abstract

The invention discloses a ureteroscope which comprises a ureteroscope body and a ureter pushing sheath clip, wherein the ureteroscope body comprises a cone section and an operating channel section; the operating channel section comprises a light source connector, an eyepiece end, a water inlet channel, a water outlet channel and an operating channel; a water inlet switch is mounted on the water inlet channel; a water outlet switch is mounted on the water outlet channel; the ureter pushing sheath clip comprises a left blade and a right blade which are respectively mounted to the outer walls of the water inlet channel and the water outlet channel through a ring-shaped connector; the ring-shaped connector can freely rotate on the outer wall of the water inlet channel or the water outlet channel. The ureteroscope has an improvement that the ureter pushing sheath clip is placed under direction vision, so that the ureter pushing sheath clip can be more easily and safer placed at a relatively ideal position of a ureter, and the risks such as operation failure and ureter damage caused by blind placement can be avoided; besides, the psychological burdens on a patient are reduced, the operation difficulty is lowered, the operation precision is improved, and the safety and the availability of a treatment process are improved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a rigid ureteroscope. Background technique [0002] With the popularization and application of ureteroscope in our country, more and more urologists use ureteroscope to solve various ureteral diseases encountered clinically. The rigid ureteroscope is a commonly used medical device in the diagnosis and treatment of urology. It is used in soft mirror surgery to check the situation in the ureter and place a guide wire before the soft mirror treatment, so as to facilitate the placement of the ureteral push sheath, and then the flexible mirror is pushed through the ureter. The sheath enters the body for surgery. However, at present, under the guidance of a rigid ureteroscope, the guide wire is put into the renal pelvis from the urethral opening, then withdraws from the rigid ureteroscope, and then the ureter with an inner core is pushed into the sheath along the guide wire, a...
