Outer wall gluing, sealing；The other end and 50 outer wall gluing, sealing of 41 outer wall of catheter body and/or the rock breaking tool；Ensure
It is reduced in rubble surgical procedure and even prevents germ and other sundries invasion patient's body in external environment；It can prevent from filling simultaneously
Fluid injection is oozed out from the nozzle of connecting tube 30, it is ensured that the vacuum suction effect of vacuum extractor.Wherein, the rock breaking tool 50 are as follows:
For Bladder stone optical fiber.
Further, ureteroscope 100 provided by above-described embodiment, the outer diameter of the shank 20 oneself and ureter
Mirror holds 10 joint 201 of pipe to the free end of shank 20 21 and is gradually reduced, convenient for stretching shank 20 by 20 free end 21 of shank
Enter in patient ureter.The internal diameter of the service aisle is protected from the free end of connecting tube 30 31 to the free end of shank 20 21
It holds and immobilizes, protrude into Bladder stone optical fiber convenient for doctor and execute rubble operation, or protrude into lithotomy forceps clamping calculus convenient for doctor.
Patient ureter's calculus situation is checked using ureteroscope 100 provided by the invention, or does ureter rubble hand
During art, need to protrude into the shank 20 of ureteroscope 100 in patient ureter first；Again by the catheter body of liquid stream conduit 40
In service aisle of 41 one end 42 by the nozzle insertion ureteroscope 100 of connecting tube 30, through and out the service aisle；Again
41 other end 44 of catheter body is connected into a vacuum extractor.Then the water inlet pipe 13 is connected into external water source；And adjust into
The injection pressure of water valve 14 and the vacuum suction pressure of vacuum extractor.External water source via water inlet pipe 13, liquid stream conduit 40 outside
The space that wall and service aisle inner wall are formed enters in patient ureter, then via circuit after the lumen of liquid stream conduit 40 to negative pressure
In aspirator, to form perfusion liquid circuit.At this time due to 20 free end 21 of shank and 41 one end of catheter body, 42 end
Between there are the water flows of certain pressure in region, therefore this regional vision understands, doctor can see the calculus situation in the region clearly.When
The region need to guarantee that calculus is crossed in 43 position of inlet opening in the catheter body 41 there are calculus and when rubble operation is done in determination
Region certain distance so just can guarantee that calculus region is exposed within sweep of the eye, execute rubble operation convenient for doctor.Wherein,
It is described to be adjusted according to actual needs apart from value, generally 1-3 centimetres.
Ureteroscope 100 provided by the present invention compares traditional ureteroscope, due in ureter rubble surgical procedure
Perfusion liquid circuit, under the premise of calculus regional vision is clear in ensuring surgical procedure, energy can be formed in patient ureter
Enough reduction of patient renal plevis pressure induces the several of urine source property septicopyemia so as to reduce after patient ureter's mirror rubble is performed the operation
Rate has further ensured the postoperative safety of patient.
The present invention also provides a kind of liquid stream conduits, referring to Fig. 1, Fig. 2, Fig. 3 and Fig. 4.Fig. 4 is that liquid stream of the invention is led
The structural schematic diagram of pipe.The liquid stream conduit 40 includes catheter body 41, and described 41 one end 42 of catheter body is by the urine output that is adapted to
In pipe mirror 100 in the service aisle of the nozzle insertion ureteroscope of connecting tube 30, through and out the service aisle；The other end
44 one vacuum extractors of connection (not shown go out)；The catheter body 41 stretches out 42 end of one end of the service aisle for sealing
Setting；The catheter body 41, which is stretched out on the tube wall of the service aisle, is provided at least one inlet opening 43, the inlet opening
43 are connected to the lumen of the catheter body 41.
Wherein, the outer diameter of the catheter body 41 of the liquid stream conduit 40 is less than the service aisle (not shown go out)
Internal diameter, the space that 41 outer wall of catheter body is formed with the service aisle inner wall are that the rock breaking tool 50 protruded into provides
Accommodation space and operating space.Wherein, the rock breaking tool are as follows: Bladder stone optical fiber.
