Endoscope with pelvic stone removing function, system and application method

Abstract

The invention provides an endoscope with a pelvic stone removing function, a system and an application method, the endoscope comprises a handle part, an insertion part and a tip part, one end of the insertion part is connected with the handle part, and the other end of the insertion part is connected with the tip part; the tip part is provided with a first working channel and a first auxiliary channel, the insertion part comprises an insertion main body, the insertion main body is provided with a second working channel and a second auxiliary channel, the first auxiliary channel is communicated with the second auxiliary channel to form an auxiliary channel, and the auxiliary channel is used for connecting auxiliary equipment and a wire thereof; the first working channel is communicated with the second working channel to form a main channel; the handle part comprises a suction interface and an instrument interface, the suction interface is connected with external negative pressure, the instrument interface is connected with an operating instrument, and the suction interface and the instrument interface are respectively communicated with the main channel. The suction connector is communicated with external negative pressure, so that stone fragments after laser lithotripsy are drained back from the main channel and discharged to the outside from the suction connector, and stone cleaning can be achieved on an operation site.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to an endoscope with the function of removing renal pelvis stones, a system and an application method. Background technique [0002] At present, urinary calculus is a common and frequently-occurring disease in urology. According to statistics, about 5%-15% of people in the world suffer from urinary calculi. With the continuous development of endoscopic technology and the continuous improvement of lithotripsy equipment and stone removal tools, the treatment of urinary calculi has undergone revolutionary changes, and traditional open surgery has gradually been replaced by minimally invasive treatment methods represented by endoscopic surgery. Instead, percutaneous nephroscopic holmium laser lithotripsy and flexible ureteroscopy are mainly used for the treatment of kidney stones. [0003] In the existing technology of using flexible ureteroscope for laser lithotrip...
