It connects；The outer tube front end is connected with the blade joint of blade part rear end, and the outer tube rear end is connected with handle front
It connects, the guidewire body rear end sequentially passes through blade part, outer tube, handle front are connected with handle rear portion, the seal wire
Hose rear end is socketed on the blade joint of blade part front end.
The polyurethane film is set as the elongated ellipsoidal structure in both ends, for blocking vanes retract into ideal circle
The occurrence of shape matches with ureter tube road shape, enhances plugging effect, reduces leakage stone.
The thin polyurethane film outer surface is provided with hydrophilic superslide coating, after facilitating blade to pass through calculus arrival calculus
Side, while ureter wall will not be damaged.
The supporting wire is set as wire, can make to keep certain intensity after blocking vanes retract, convenient for blocking calculus
And the movement of rubble.
The guidewire body outer surface is provided with superslide coating.
The development point setting is blocking on the inside of blade inner support silk, is conducive to user and determines during surgery instrument
Position.
The utility model structure is simple, is skillfully constructed, is easy to use, when in use, the utility model is logical by operation
Road is connected with the operative site of patient, and instrument blade can be sent to calculus distal end and will be blocked as needed by the utility model
Vanes retract forms operation path at regular circle plugging structure and blocks, and the intake-outlet by being arranged above, discharge
Physiological saline carries out unidirectional timely flushing to the calculus of the affected area below plugging structure, or is perfused by ureteroscope channel
Physiological saline aspirates physiological saline by the intake-outlet of this structure, realizes unidirectional cleaning in time, ensure that when cleaning calculus
The cleaning in the operation path visual field, and compared to existing scheme, the saline volume for needing to rinse is less, reduces to patient's body
