Ureteroscope with bending-degree-adjustable ureteroscope body and fixing mechanism of ureteroscope

Abstract

The invention discloses a ureteroscope with the bending degree of a ureteroscope body adjustable and a fixing mechanism of the ureteroscope, and particularly relates to the field of ureteroscopes, the ureteroscope comprises a holding box and an elastic hose, the elastic hose is arranged on one side of the holding box in a communicating mode, the top of the holding box is provided with a liquid inlet pipe in a communicating mode, the outer wall of the liquid inlet pipe is provided with a water inlet valve, and the bottom of the holding box is provided with a liquid drainage pipe in a communicating mode; a drainage valve is arranged on the outer wall of the drainage pipe, a partition plate is fixedly connected to the inner wall of the elastic hose, a supporting through pipe is fixedly installed on one side of the partition plate, a movable column is arranged on the inner wall of the supporting through pipe, a movable ball is fixedly installed at one end of the movable column, and a lens is fixedly connected to the outer wall of the movable ball. By arranging the elastic hose and the partition plate, a medical worker can crush stones by using the lens and the laser lithotripter, and then discharges the stones from the body of a patient through water circulation formed by the liquid inlet pipe and the liquid discharge pipe, so that the problem that the stones in the body of the male patient can be taken out in two times to bring discomfort to the patient is solved.

Description

technical field [0001] The invention relates to the technical field of ureteroscopes, and more particularly, to a ureteroscope with adjustable mirror body curvature and a fixing mechanism thereof. Background technique [0002] Ureteroscope is a slender instrument composed of optical fiber, working lumen and various working accessories for different purposes. The slender speculum enters the ureter with a diameter of 0.2 cm to 0.5 cm through the urethra, bladder, and ureteral orifice. Under direct vision or with the help of a TV monitoring system, the lesions in the ureter can be clearly observed. Diagnosis and treatment of ureteral diseases such as stones, tumors, etc. [0003] The traditional ureteroscope can only simply confirm the position of the stone when examining the urinary tract of male patients, and cannot remove the stone. The calculi can only be removed by inserting the tract twice, which not only complicates the work process, but also increases the discomfort o...

Problems solved by technology

[0003] Traditional ureteroscopy can only simply confirm the location of stones when examining the urinary tract of male patients, but cannot remove the stones. It is also necessary to insert the treatment tube into the patient's urinary tract again to crush and remove the stones. The calculi can only be removed by inserting the urinary tract twice, which not only complicates the workflow, but also increases the discomfort of the patient. Therefore, how to design a ureteroscope that can crush and remove the calculus in the male urinary tract has become our current solution. The problem
