Abstract

The invention provides a ureter negative-pressure calculus removing soft endoscope sheath. According to the technical scheme, the ureter negative-pressure calculus removing soft endoscope sheath is characterized by comprising an air compression device; the air compression device is provided with a negative-pressure pipe; the negative-pressure pipe is connected with a waste water tank; the waste water tank is connected with a cleaning pipe; a guide wire is provided with a drainage channel and a connector; the connector is provided with a first connecting port; the first connecting port communicates with the drainage channel; and the first connecting port is connected with the cleaning pipe. The ureter negative-pressure calculus removing soft endoscope sheath has the following beneficial effects that after lithotripsy, the guide wire is inserted into an insertion hole, penetrates through a guide hole and is inserted into the urethra, and the air compression device is started to provide negative pressure to guide the broken calculus to enter the cleaning pipe along with urine, so that the broken calculus is guided into the waste water tank by the cleaning pipe, the broken calculus cleaning effect is achieved, and the broken calculus is easier to clean compared with the mode of natural calculus discharging, and therefore, a better treatment effect is achieved, discomfort caused by discharging broken calculus can be reduced, and the cleaning speed is higher.

Description

technical field [0001] The invention relates to a soft mirror sheath, more specifically, it relates to a soft mirror sheath for ureteral negative pressure stone clearing. Background technique [0002] Ureteroscopic lithotripsy is to use a fine mirror with a diameter of about 3mm to insert the ureter through the urethra and bladder to crush and remove ureteral or kidney stones. It uses the human body's natural urinary system cavity without making any incisions on the body. It is a pure urological laparoscopic minimally invasive surgery. The flexible mirror sheath is inserted into the urethra first, and then the guide wire is pulled out for the insertion of the flexible mirror to guide the flexible mirror into the ureter to crush the stones. However, after crushing the stones, the effect of natural stone removal is not good, and the broken stones cannot be fully removed. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the purpose of the pres...
