The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is described in further detail.Following examples are used to illustrate this utility model, but are not used for limiting scope of the present utility model.
Conveyer device of the present utility model comprises conductor 1 and carrier 2 that cooperates with conductor 1 and convergent divergent channel 3.
Be illustrated in figure 1 as the front view of the conductor 1 of this utility model embodiment, it comprises: guiding sheath pipe 4, guiding sheath pipe connections 12, fastening nut 13 and tube for transfusion 18.One end of guiding sheath pipe connections 12 is arranged at an end of guiding sheath pipe 4.The other end of guiding sheath pipe connections 12 is arranged at an end (guiding sheath pipe connections 12 is threaded, and fastening nut 13 is connected with guiding sheath pipe connections 12 by screw thread) of fastening nut 13, and guiding sheath pipe connections 12 is provided with tube for transfusion 18.Guiding sheath pipe connections 12 is shown in Fig. 7 a and 7b.Silica gel circle 14 is gone into wherein from the C end plug of guiding sheath pipe connections 12 along direction shown in the arrow, after fastening nut 13 (shown in Fig. 8 a and 8b) is screwed on the connector 12C end, the D end of fastening nut 13 protrudes, make extruding silica gel circle 14 in the rundown process, make the distortion of silica gel circle, the internal diameter of silica gel circle diminishes, and therefore can change the internal diameter of silica gel circle in this way, it can well be cooperated with interior pipe, accomplish that internal diameter is adjustable and can prevent leak-stopping blood.Guiding sheath pipe 4 usefulness Pebax expect extrusion molding, inner with metal knitted silk reinforcement, its intensity, fold resistance are strengthened, a plurality of development rings (for example 5) have been processed at head, the ring that develops is to install additional in guiding sheath pipe drawing pipe process, and tungsten filament is wrapped in and forms the ring that develops on the tubing, can't see from pipe outer surface, can under X-ray, develop, can avoid contacting of heavy metal and blood in the operation process like this.After plugging device 19 is written into by carrier 2, be arranged at the development ring of an end aligned proximal (as a reference) of the plugging device 19 of push rod 8 ends with heart, the other end can be at different development interannulars according to the difference of plugging device size, the ring that develops can make the doctor clearly see the position that auto levelizer is carried under the X-ray in surgical environments, the plugging device of different size is aimed at different development rings, the development ring of far-end is aimed at the left auricle opening, discharge plugging device, can guarantee that plugging device discharges the back and aims at the left auricle opening.
Thereby an end of convergent divergent channel 3 can pass guiding sheath pipe 4, guiding sheath pipe connections 12 and fastening nut 13 to be cooperated with guiding sheath pipe 4.As shown in Figure 2, convergent divergent channel 3 is processed into the taper at 30 degree angles from the end that guiding sheath pipe 4 protrudes, be beneficial to the operation of puncture interatrial septum, and tail end adds with the UV curing mode loads onto a haemostatic valve 7, and haemostatic valve is injection molded into the PC material.As shown in Figure 5, rubber disk 17 is filled in the pipe, cracks in the middle of the rubber disk, plays the effect of check valve, anti-leak-stopping blood when guiding wire therefrom passes.Convergent divergent channel 3 is made by high density polyethylene (HDPE), and skin-friction coefficient is little, and head end is softer, can fit tightly with convergent divergent channel 3.Refer again to Fig. 2, after convergent divergent channel 3 inserted guiding sheath pipe 4, convergent divergent channel 3 can freely be twitched in guiding sheath pipe 4.
As shown in Figure 4, carrier 2 comprises: push rod 8, delivery sheath 9, handle 10, Y-valve 15 and delivery sheath connector 16.Delivery sheath 9 one ends are arranged at an end (passing through curing mode) of delivery sheath connector 16, delivery sheath connector 16 other ends are arranged at an end of Y-valve 15, an end that pushes pipe 8 passes delivery sheath 9, delivery sheath connector 16 and Y-valve 15, one end of push rod 8 is not from delivery sheath 9 protrusions and be provided with plugging device 19, and the other end of push rod 8 is provided with tail end handle 10.As shown in Figure 4, thus delivery sheath 9 can pass guiding sheath pipe 4, guiding sheath pipe connections 12 and fastening nut 13 to be cooperated with guiding sheath pipe 4.After carrier 2 is being with in plugging device 19 (plugging device 19 compression the enter carrier 2) conductor of packing into 1, the ring that develops of the near-end on the ring 6 alignment conductors 1 that develop, thus guaranteeing that plugging device 19 and conductor 1 near-end develop to encircle aligns.Push rod 8 is the stainless steel spring bar, and inner core is that stainless steel silk is strengthened, and head end welding one is used to be provided with the screw element of plugging device 19.Tail end handle 10 slides on push rod 8, difference according to plugging device 19 specifications can be adjusted to diverse location, tail end handle 10 is close together with the Y-valve far-end in the dispose procedure, expression plugging device 19 discharges fully, be convenient to understand plugging device 19 releasing degrees, discharge the back fully and counterclockwise rotate tail end handle 10, plugging device 19 is broken away from push rod 8.Determine the length of tail end handle 10 distance Y type valves 15 according to the length of different plugging devices 19, can discharge plugging device 19 fully after directly pushing respective distance, make doctor's operation process on top of.
Guiding sheath pipe 4 have single curved and two bend two kinds different curved.Different according to the relative position of left auricle and right auricle, the difference of interatrial septum height is selected suitable curved.Occupation mode is illustrated in figure 9 as the sketch map that uses single curved situation, Figure 10 shows that the sketch map that uses two curved situations.
In zoopery and clinical practice, select different curved conveyer devices with left auricle radiography result according to transesophageal echocardiography.As shown in figure 10, the puncture operation is puncture right auricle 22 earlier, the lancet puncture interatrial septum 27 then, puncture needle is withdrawn from, carry 0.035 inch guiding wire, conductor is delivered to left atrium along seal wire, convergent divergent channel 3 is withdrawn from, along pigtail conduit of conductor 1 input, will guide sheath pipe 4 and be transported in the left auricle 23.
The above only is an embodiment of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from this utility model know-why; can also make some improvement and modification, these improve and modification also should be considered as protection domain of the present utility model.
