Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a side-viewing side-opening uretero-nephroscope, which can solve the problem that the peeping direction of the ureter-nephroscope lens is limited, and it is impossible to see and evaluate the pathological changes such as gravel in the side of the renal pelvis and the middle and lower calices. And the water outlet of the water inlet channel cannot effectively wash away the gravel in the side of the renal pelvis and the middle and lower calyx, and cannot guide the lithotripsy optical fiber (laser fiber) and instruments to crush and operate the stones in the side of the renal pelvis and in the middle and lower calyx

Abstract

The invention discloses a side-viewing and side-opening ureterorenoscope and relates to the field of medical instruments. The side-viewing and side-opening ureterorenoscope comprises a nephroscope tube, a light guide bundle interface, an eyepiece slide, a liquid inlet and a surgical instrument access are arranged on an eyepiece slide body, a sheath tube sleeves the nephroscope tube from outside and is fittingly connected with the nephroscope tube through a sheath body, the sheath tube is shorter than the nephroscope tube, a water yielding channel is formed between the sheath tube and the nephroscope tube, and the top of the nephroscope is provided with an obliquely-arranged oblique-viewing objective or a direct-viewing objective while the side face of the top of the nephroscope is providedwith a side-viewing objective; a side opening communicated with the surgical instrument access and the liquid inlet is formed under the oblique-viewing objective or the side-viewing objective. By thearrangement, problems that the ureterorenoscope cannot detect and treat lesions on the renal pelvis side and part of the lesions in the middle and lower calyx and gravel on the renal pelvis side andthe middle and lower calyx cannot be flushed effectively through yielding water of a straight flushing channel can be solved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a surgical device used for lateral surgical treatment of kidney stones through the urethra and ureter through a hard tube endoscope. Background technique [0002] In urological surgery, interventional therapy (minimally invasive or endoscopic technique) is required to remove kidney stones, and the middle and lower calices of kidney stones must undergo endoluminal fiberoptic ureteroscopy (soft endoscopy, endoscopic technique) Or minimally invasive percutaneous nephroscopy (minimally invasive surgery) can crush stones or remove stones. These two surgical methods and techniques have the disadvantages of high risk, expensive supporting equipment, high technical requirements, and high medical expenses. At present, there is a transurethral ureteral rigid convective negative pressure channel lithotripsy (endoscopic technique), which can avoid the above shortcomings, but it is d...
