Shape, the sacculus right end are equipped with Y shape passway 3, and Y shape passway 3 is connected to form fluid passage 5 with three sacculus 2, and described leads
Silk inner core 1 is equipped with scale 4, and graduation mark 4 is by showing with the coin marking of seal wire inner core different colours.
In order to further illustrate the utility model, the application background of lower the utility model is first introduced：
Ureteroscopy due to no edge of a knife, wound is small, recovery is fast and the favor by doctor and patient.Ureteroscope hand
Art generally takes insertion guiding catheter, and ureteroscope is made to enter ureter along guiding catheter, then recycles the side of ureteroscope
Method carries out related operation, and guiding catheter is typically all curved hose, it is not easy to be straightened, at this time just needs by one
Long seal wire guides, and ureter is very thin, and caliber is generally at 0.5-0.7 centimetres, and there are three narrow for ureter
Portion, first migrates place in renal plevis and ureter（Ureter section start）, second is being crossed minor pelvis inlet, the last one
In the inside for entering the bladder wall.It is that calculus, clot and necrotic tissue are easy the position stopped that these are narrow.Therefore for urine output
The entrance of Guan Jing becomes a difficulty, nowadays general to be entered by expander, but expander is difficult to be only capable of protecting after entering
It is narrow into first to demonstrate,prove ureteroscope, subsequent narrow part then hardly enters, if calculus occurs in the second third stenosis, or
