The essence of transthecal endoscopic stone extraction is a minimally invasive surgical procedure in which a hollow sheath is inserted into the human body and reaches the surgical site (renal pelvis and upper ureter), and then the sheath is placed into the endoscopic stone extraction. The middle water injection channel infuses normal saline into the kidney to ensure a clear surgical field of vision; stone extraction methods mainly rely on stone extraction forceps or stone baskets or high-pressure water to wash out stones, which takes a long time and is not clean

Embodiment Construction
[0018] A flexible ureteroscope lithotripsy treatment device of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0019] With reference to the accompanying drawings, a flexible ureteroscope lithotripsy treatment device includes a syringe 1, a ureteral sheath 2, and an insertion part;
[0020] The insertion part includes a coarse flushing tube 3 and a fine flushing tube 4, one end of the coarse flushing tube 3 is connected to the injection end of the syringe 1, and one end of the fine flushing tube 4 is connected to the injection end of the syringe 1;
[0021] A coarse irrigation tube 3 and a fine irrigation tube 4 can be inserted into the ureteral sheath 2 .
[0022] The inner diameter of the ureteral sheath 2 is greater than the summed diameter of the coarse irrigation tube 3 and the fine irrigation tube 4 .
[0023] The lengths of the coarse irrigation tube 3 and the fine irrigation tube 4 are greater than the le...

The invention discloses a flexible ureteroscope lithotripsy treatment device which comprises an injector, a ureter sheath and an insertion part. The insertion part comprises a thick flushing pipe and a thin flushing pipe, one end of the thick flushing pipe is connected with the injection end of the injector, and one end of the thin flushing pipe is connected with the injection end of the injector; and the thick flushing pipe and the thin flushing pipe can be inserted into the ureter sheath. The invention further provides a specific use method of the lithotripsy treatment device. The structure is simple and the operation is convenient; and the thick flushing pipe and the thin flushing pipe are combined, so that flushing and calculus removing can be synchronously carried out, and the calculus removing time is shortened.
Description
technical field [0001] The invention relates to the technical field of medical devices, in particular to a lithotripsy treatment device for a flexible ureteroscope. Background technique [0002] Calculus is a common clinical disease. Transthecal endoscopic stone removal operations such as flexible ureteroscopy laser lithotripsy and flexible ureteroscopy stone removal are the most common treatment methods for kidney and ureter stones. The essence of transthecal endoscopic stone extraction is a minimally invasive surgical procedure in which a hollow sheath is inserted into the human body and reaches the surgical site (renal pelvis and upper ureter), and then the sheath is placed into the endoscopic stone extraction. The middle water injection channel infuses normal saline into the kidney to ensure a clear surgical field of view; stone removal methods mainly rely on stone removal forceps or a stone basket to remove stones repeatedly or high-pressure water flow to wash out stone...
