Description
Technical field
This utility model relates to a kind of medical apparatus, specifically a kind of rotary valve liver and gall drainage wash pipe.
Background technology
Carry out at ultrasound wave or x-ray fluoroscopy Guided Percutaneous skin the common Disposal Measures that hepatic duct puncture drainage is the obstructive jaundice that causes of Hepatoma therapy, common hepatic duct cell carcinoma and cancer of pancreas, simple, clinical effectiveness good.Existing liver and gall drainage tube mostly adopts a drag-line traction taper pipe close, adjusts the gap between pipe close and mozzle, thereby reaches the aperture of draining hole, regulates the object of drainage speed.But this direct-connected governor motion movable distance is short, and the accuracy of adjusting is not high, and misoperation also easily scratches patient, causes secondary injury.Chinese patent 2011201510431 discloses a kind of " liver and gall drainage wash pipe ", adopts movably telescopic tube to be sleeved in puncture tube, utilizes stop portions conduction hole in telescopic tube moving process to reach the object that regulates drainage speed.Although this technical scheme is safer reliable, but still exists governor motion range ability short, is difficult to the defect of accurate adjustment.In addition, because puncture tube diameter is less, telescopic tube is arranged in puncture tube, and governor motion can only be arranged on outside puncture tube, and connection between the two and sealing problem are all difficult to solve.
Summary of the invention
The purpose of this utility model is to provide a kind of simple in structure, easy to use, rotary valve liver and gall drainage wash pipe that accommodation accuracy is high, safe and reliable.
In order to reach above object, technical scheme that this utility model adopts is: this rotary valve liver and gall drainage wash pipe comprises the puncture tube with oval puncturing head, be connected to the stream guiding tube on puncture tube, front end at puncturing head and puncture tube is provided with conduction hole, between puncture tube and stream guiding tube, be provided with rotary valve current-limiting apparatus, described rotary valve current-limiting apparatus comprises the terminal pad that is connected to puncture tube rear end, be connected to the valve body of stream guiding tube front end, described valve body comprises the ring flange being threaded connection on terminal pad, be arranged on the valve core tube of ring flange center, fixed valve plate and moving valve plate are installed in the inner chamber of described valve core tube, on described fixed valve plate and moving valve plate with the valve opening cooperatively interacting, fixed valve plate is fixedly connected with valve core tube, moving valve plate is rotatably inlaid in valve core tube, on valve core tube outside moving valve plate and ring flange, be provided with fan-shaped cavity, multiple fan-shaped cavities are uniformly distributed around moving valve plate, the outside of ring flange is set with and regulates hands ring, between described adjusting bracelet and moving valve plate, be fixedly connected with spoke, described spoke is arranged in fan-shaped cavity.
The center of described terminal pad is provided with installing hole, and the rear end of described puncture tube, with the flanging turning up, is provided with sealing ring between described flanging and terminal pad; Mouth of pipe place in the rear end of puncture tube is provided with taper chamfering, and the front end of described valve core tube is with the canalis spinalis of coupling taper chamfering.
The beneficial effects of the utility model are: adopt valve block throttle style, regulate the diameter of bracelet can not be subject to the restriction of puncture tube diameter, good hand touch, easy to use, accommodation accuracy is high, good sealing effect, safe and reliable.
Brief description of the drawings
Fig. 1 is the structural representation of an embodiment of this utility model.
Fig. 2 is the A-A cutaway view of Fig. 1 embodiment.
Detailed description of the invention
As shown in Figure 1, rotary valve liver and gall drainage wash pipe described in the utility model, comprises with the puncture tube 2 of oval puncturing head 1, is connected to the stream guiding tube 3 on puncture tube 2, is provided with conduction hole 4 at the front end of puncturing head 1 and puncture tube 2.When use, by puncture tube 2, in skin penetrating enters patient body, tissue fluid enters in the inner chamber of puncture tube 2 by conduction hole 4, and is transferred in the containers such as drainage bag through stream guiding tube 3.
For realizing the scalable of water conservancy diversion speed, as Fig. 1, shown in Fig. 2, between puncture tube 2 and stream guiding tube 3, be provided with rotary valve current-limiting apparatus, described rotary valve current-limiting apparatus comprises the terminal pad 5 that is connected to puncture tube 2 rear ends, be connected to the valve body of stream guiding tube 3 front ends, described valve body comprises the ring flange 6 being threaded connection on terminal pad 5, be arranged on the valve core tube 7 of ring flange 6 centers, fixed valve plate 8 and moving valve plate 9 are installed in the inner chamber of described valve core tube 7, on described fixed valve plate 8 and moving valve plate 9 with the valve opening cooperatively interacting, fixed valve plate 8 is fixedly connected with valve core tube 7, moving valve plate 9 is rotatably inlaid in valve core tube 7, on the valve core tube 7 in moving valve plate 9 outsides and ring flange 6, be provided with fan-shaped cavity 10, multiple fan-shaped cavities 10 are uniformly distributed around moving valve plate 9, the outside of ring flange 6 is set with and regulates bracelet 11, between described adjusting bracelet 11 and moving valve plate 9, be fixedly connected with spoke 12, described spoke 12 is arranged in fan-shaped cavity 10.Rotate and regulate bracelet 11 can drive moving valve plate 9 synchronous rotaries, thereby make moving valve plate 9 rotation relative to fixed valve plate 8, moving valve plate 9 has different laps when being in diverse location from the valve opening on fixed valve plate 8, only have the valve opening of lap be only liquid effectively by cross section, therefore rotate the area that moving valve plate 9 changes valve opening lap and can reach the object that regulates drainage speed.The shape of valve opening and position can have multiple design as required, and this is the conventional design of the art, does not repeat them here.
In addition, accurately location and excellent sealing when rotary valve current-limiting apparatus is connected with puncture tube 2, as shown in Figure 1, the center of described terminal pad 5 is provided with installing hole, the rear end of described puncture tube 2, with the flanging turning up, is provided with sealing ring 13 between described flanging and terminal pad 5; Mouth of pipe place in the rear end of puncture tube 2 is provided with taper chamfering, and the front end of described valve core tube 7 is with the canalis spinalis of coupling taper chamfering.Taper chamfering has not only improved sealing effectiveness but also can play the effect of guiding location with coordinating of canalis spinalis, facilitates the docking of the mouth of pipe; Terminal pad 5 is connected with the plug-in of puncture tube 2 can be for convenience detach, clean, and can improve sealing effectiveness by sealing ring again.
