Specific implementation mode
The common intra-bladder instillation mode of surgical clinical at present, by taking Urology Surgery as an example, there are mainly two types of：
Charge pump is perfused, and uses automatic control technology, by the pressure of pressure sensor control perfusion, and can be in panel
Upper setting or the actual pressure for showing irrigation flow, perfusion manifold pressure the upper limit, being perfused in pipeline.Its advantage is that can continuously certainly
Dynamicization is perfused, but the disadvantage is that groundwater increment is larger, can not be perfused according to concrete operations and the timely intense adjustment of visual area situation in art
Flow, and postoperative complication is more.
Manual injection device is perfused, because more using hysteroscope charge pump perfusion postoperative complications, many clinical centers use
Syringe, i.e., be connected by manual injection device perfusion with hysteroscope, and assistant coordinates the perfusion of operator doctor manual injection device in art.Its is excellent
Point is that have good controllability, can finely adjust irrigation flow in time according to visual area and concrete operations, and pass through injection
Device perfusion can perceive injection pressure, avoid chamber pressure excessively high, the disadvantage is that can not continuously be noted because syringe need to draw water repeatedly
Water needs to frequently replace another syringe for filling fluid in filling process, or current injector is extracted out, from fluid container
Middle withdrawn fluid, then the fluid in syringe is injected in hysteroscope or body cavities, syringe is replaced or takes out syringe again
It takes fluid that perfusion can be caused to interrupt, influences surgical procedure, and then affect the accuracy of operation, extend operating time, even
The operation risk brought, in addition, replacing syringe can force air into body cavities, the light of bubble meeting reflecting cavity mirror cold light source
Line influences surgical procedure.
The application passes through at least two interfaces and fluid by the way that syringe is improved to enclosed construction on enclosed construction
Communication apparatus is connected to so that continuously closing knot is discharged in fluid by fluid connecting device when plunger moves back and forth inside enclosed construction
Structure, to realize the continuous pouring of fluid and the controllability of perfusion simultaneously.
Certainly, any technical solution for implementing the embodiment of the present application does not need to reach simultaneously above all excellent necessarily
Point.
In order to make those skilled in the art more fully understand the technical solution in the embodiment of the present application, below in conjunction with the application
