Abstract
The utility model discloses a kind of puncture needle with flow regulator, comprise needle body; It also comprises the flow regulator for controlling puncture needle flow, and this flow regulator comprises the pedestal being arranged on needle body end, and pedestal is provided with gate and the inner chamber tight fit of this gate and puncture needle, described gate is connected with a control stick; When drived control bar closed shutter, the inner chamber of closing gate puncture needle, when drived control bar starting gate, the inner chamber of puncture needle opened by gate.Puncture needle of the present utility model can carry out open and close controlling to reach the function of Flow-rate adjustment to through puncture needle inner chamber.
Description
Technical field
This utility model relates to puncture needle, more particularly, relates to a kind of puncture needle with flow regulator.
Background technology
Bladder trocar carries out fistulation operation for percutaneous puncture bladder.Existing puncture needle is completely through, there is no the device of limited flow, because the puncture needle bore of large model is larger, syringe needle can make intravesical pressure change rapidly when arriving bladder, bladder shrinks rapidly, urine sprays fast, easily damages bladder function, and urine is easy contaminated operation environment also.How to solve above-mentioned technical deficiency, become technical barrier urgently to be resolved hurrily.
Utility model content
The purpose of this utility model is to provide a kind of puncture needle with flow regulator, and this puncture needle can carry out open and close controlling to reach the function of Flow-rate adjustment to through puncture needle inner chamber.
For achieving the above object, this utility model have employed following technical scheme:
With a puncture needle for flow regulator, comprise needle body; It also comprises the flow regulator for controlling puncture needle flow, and this flow regulator comprises the pedestal being arranged on needle body end, and pedestal is provided with gate and the inner chamber tight fit of this gate and puncture needle, described gate is connected with a control stick; When drived control bar closed shutter, the inner chamber of closing gate puncture needle, when drived control bar starting gate, the inner chamber of puncture needle opened by gate.
Described pedestal is also provided with the gate groove matched with described gate.
Described control stick is rotatable control stick.
Described gate is provided with scalable projection, pedestal is provided with the multiple locating slots coordinated with scalable projection, described control stick is provided with the button of scalable projection.
After employing said structure, this utility model has following beneficial effect:
In this utility model, when drived control bar closed shutter, the inner chamber of closing gate puncture needle, when drived control bar starting gate, the inner chamber of puncture needle opened by gate.Puncture needle of the present utility model can carry out open and close controlling to reach the function of Flow-rate adjustment to through puncture needle inner chamber.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is flow regulator structural representation in the on state;
Fig. 3 be flow regulator in off position under structural representation.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is described in further detail.
Shown in Fig. 1, Fig. 2, Fig. 3, a kind of puncture needle with flow regulator, comprises needle body 1; It also comprises the flow regulator 2 for controlling puncture needle flow, this flow regulator 2 comprises the pedestal 21 being arranged on needle body 1 end, pedestal 21 is provided with gate 23 and the inner chamber tight fit of this gate 23 and puncture needle, described gate 23 is connected with a control stick 22; When drived control bar 22 closed shutter 23, the inner chamber of puncture needle closed by gate 23, and when drived control bar 22 starting gate 23, the inner chamber of puncture needle opened by gate 23.
In addition, described pedestal 21 can also be provided with the gate groove 24 matched with described gate 23.Described control stick 22 is rotatable control stick.Scalable projection (not shown) can be provided with on described gate 23, pedestal 21 is provided with the multiple locating slots (not shown) coordinated with scalable projection, described control stick 22 is provided with the button (not shown) of scalable projection, thus scalable projection can be driven to be connected with described locating slot by the button on control stick 22 to coordinate, play and control the effect of flow at certain position, effect is better.
When this utility model uses, when closed shutter 23, the inner chamber of puncture needle closed by gate 23; When starting gate 23, the inner chamber of puncture needle opened by gate 23.
Above-mentioned embodiment is this utility model preferably embodiment; but embodiment of the present utility model is not by the restriction of above-mentioned embodiment; and other any do under not deviating from spirit of the present utility model and principle change, modification, substitute, combine, simplify; all should be the substitute mode of equivalence, be included within protection domain of the present utility model.
