The water gone out absorbs, and " the controllable attraction system of central negative pressure " is not the designing points of the present invention, is described in detail not to this.
1. the advantages of present invention is brought is：One channel tail end of penstock carries the switch of regulating water flow, water pump
After the completion of pressure and flow rate set, operating field can also be controlled clearly minimum further according to the requirement of operating field, regulating water flow
Hydraulic pressure and flow；Another tail end of penstock is the channel of laser fiber, and two channels of penstock front end are put down side by side
Row ensure that can adjust optical fiber contact calculus during Rotatable water inlet conduit smashes position, and lasting bath ensure that operating field
Clearly, the safety that ensure that rubble is accurately positioned, and improves rubble and removes calculus speed.
2. it is potential lacuna to add among tough water seal, not only had the function of that penstock facilitated disengaging, but also had sealing water and gas
The precise effects of body.Tough water seal is added to have the effect of fixed penstock concurrently other than blocking the function of water, reduce operator
Work difficulty and complicated procedures.
3. during operation, into the water of operative site, excrete, make through the service aisle lacuna other than penstock
The water of operative site is in sustained low pressure recurrent state；Negative pressure catheter extension tube is connected to the side of ureteroscope or the Inlet and outlet water of rectangle
At mouthful, according to the filling degree of operating field and degree of getting a clear view, it can be switched by adjusting the water outlet of ureteroscope, adjusted at any time
The pressure of whole vacuum suction is to ensure that operating field is clear, hydrostatic pressure is stable, rubble speed is accelerated, the weight of operating time shortening
One of factor is wanted, ensure that the safe efficient of operation.
4. suit contains all auxiliary of Ho.YAG laser lithotripsy under ureteroscope to Ho.YAG laser lithotripsy safely under auxiliary ureteroscope
Medical treatment consumptive materials are helped, it is easy to use, workflow is simplified, has saved operating time.Disposable entire package and disinfection, are saved into
This, reduces expense.
The advantageous effect of patent of the present invention is：Operating field is clear, pressure stability, rubble speed are accelerated, operating time is short, increases
Add the safety of operation, prevent or reduce the generation of septicopyemia.
Description of the drawings

Fig. 3 is the structure diagram that water switchs in the present invention.
In attached drawing：1st, penstock；2nd, metal die；3rd, small water seal；4th, water seal is thickeied；5th, central negative pressure, which controllably attracts, is
System；6th, ureteroscope；7th, ureteroscope water outlet；8th, water switchs；9th, water pump.
Specific embodiment
1 ~ 2 couple of present invention is further detailed with reference to the accompanying drawings of the specification：
Metal die 2 is put into one of chamber of penstock 1 first, penstock 1 is then inserted into ureteroscope 6,
The inlet of middle ureteroscope 6, which is provided with, thickeies water seal 4, thickeies water seal 4 and plays the role of fixed position and sealing, prevents water
It is flowed out from inlet, another chamber of penstock is inserted into laser fiber, wherein the tail portion for being inserted into the chamber of laser fiber is provided with
Small water seal, wherein the tail portion for being inserted into one end of metal die 2 is connected with section of water switch 8 and water pump 9, wherein penstock 1
Face is " ∞ " shape, and penstock 1 extracts metal die 2 out after entering to ureteroscope 6, and 9 water source of water pump is transmitted to penstock 1,
By 8 control flow size of water switch, the wherein device similar for transfusion bottle flow controller of water switch 8, wherein water is opened
Close as a diagonal framework, by wherein one of penstock 1 put inside it, by idler wheel displacement squeeze the space of flow come
The size of water is controlled, water source is flowed out from the forepart of penstock 1, the impurity in the interference such as blood in the operation visual field is carried out clear
Reason, the water source of outflow by penstock 1 and thicken the gap between water seal 4, ureteroscope water outlet 7 are flowed into, in order to more
Good cycle, the controllable attraction system of central negative pressure is added in one end of ureteroscope water outlet 7, the liquid of outflow is born
Pressure is sucked out, and accelerates cycle in this way, another mouth of ureteroscope is with switch, due to the controllable attraction system of central negative pressure
Complexity is adjusted, the switch of another mouthful can be opened or be closed, you can without adjusting the controllable attraction system of central negative pressure
Pressure facilitates the operation of nurse.
Two-chamber plastic catheter of the tube body section of penstock for " ∞ " shape, Multiple Type, maximum major diameter adapt to ureter
The size of mirror chamber front end, 1 tail end of double channel catheter separate, shorter 2cm of a chamber or so, connect non-porous small water seal 2；Another chamber is longer
50cm or so, the switch 1.1 with regulating water flow；The directly opposite stone location to be smashed in the front end of two-chamber plastic catheter,
The length of tube body is 50cm；Metal die position 2 in penstock, play support and auxiliary penstock 1 pass through thicken water seal 4 into
Enter the effect in ureteroscope.
Thickening water seal has potential straight crack, and slightly frictional resistance, existing ureteroscope is common when penstock passes in and out
The water blockoff function of water seal, and play the role of fixed penstock.
Embodiment
After patient's routine operation prepares, open Ho.YAG laser lithotripsy condom equipment under auxiliary ureteroscope and use, connect
Camera system of ureteroscope etc..Then tough water seal is added to be mounted on ureteroscope, metal die front end is only slight beyond water inlet
Potentially straight crack enters in ureteroscope by adding tough water seal for the front end of conduit, support and auxiliary penstock, close to reach
During ureteroscope front end, metal die is extracted out；The channel tail end connection water pump pipeline of penstock, in the another of penstock
One channel tail end and water seal cap are inserted into laser fiber.One end of negative pressure catheter extension tube is connected to the side or rectangle of ureteroscope
Intake-outlet at, the other end connection the controllable attraction system of central negative pressure.Ureteroscope routinely enters under ureteral calculi position
Side makes the front end of penstock the laser fiber contact stone location to be smashed be stretched out, according to operation directly against surgical field of view
Wild requirement regulating water flow and pressure, there is certain rubble space in holding part of persistently washing by water through penstock, further according to hand
The filling degree and degree of getting a clear view of visual area, patient or assistant adjust the pressure of vacuum suction at any time, and the water of operative site is in
Persistent loop state, rubble powder are sucked out in time, rubble process always in operating field is clear, hydrostatic pressure rational state,
It ensure that operation is efficiently and safely completed.After powdered knapper makees, calculus taking-up is no longer carried out, conventional progress is next
The techniqueflow of step completes double J pipe merging work.If incomplete powdered rubble prepares to take out part compared with maximum size particle
When, it is changed to common Taking Ureterolith under Ureteroscope technology.
