1. end sockets among the figure 2. expand and put pipe, 3. lack side pipe, 4. go up the directed wing, 5. core bar, 6. spring, 7. pipe close, 8. time directed wing.

The specific embodiment

At Fig. 1, Fig. 2, among Fig. 3, this utility model is provided with to expand puts pipe 2, it is the open type structure that pipe two ends, 2 left and right sides are put in expansion, expand and to put pipe 2 rear portions and be connected with expansion and put the short side pipe 3 of pipe 2 intracavity inter-connections, expansion is put pipe 2 left ends and is bent to arcuate structure, expand on the chamber wall of putting pipe 2 left sides and be processed with liquid outlet, expansion is put pipe 2 right-hand members and is fixed with the directed wing 4, pipe 2 right-hand member shutoff are put in expansion pipe close 7, pipe close 7 cooperates with locking hole on the last directed wing 4 through plug pin and spring, core bar 5 passes pipe close 7 and is plugged in to expand and puts in pipe 2 inner chambers, core bar 5 left ends are connected with end socket 1, end socket 1 can be processed into difformity according to different needs, if need puncture then end socket 1 is processed into conical tip, if only be used to expand then end socket 1 is processed into bullet shape, core bar 5 right-hand members are connected with down the directed wing 8, the directed wing 8 is provided with latch down, and this latch cooperates with the jack locking at the last directed wing 4 rear portions.

This utility model can be walked around the advancing important organ that stops for realizing, directed arrival has the position that perforator is difficult to arrive now, ad hoc have two kinds of different models, every kind of model expands by one puts pipe 2 and twin-core promptly a round end core and a tip core constitutes, pipe 2 is put in every kind of model expansion all left end hole and right-hand member hole, the equal and opposite in direction in pipe 2 left end holes and right-hand member hole is put in the expansion of first kind of model, its end socket 1 is a bullet shape, it is much smaller that its right-hand member hole of pipe 2 left end boring ratios is put in the expansion of second kind of type, and its end socket 1 is conical tip.Expand and to put pipe 2 rear portions one side and be provided with short side pipe 3 with its same specification, both are with about 20 degree angle traffic, make expansion put pipe 2 and be y-type structure, the pipe rear portion is put in expansion the directed wing 4 on, go up the directed wing 4 circular hole I and circular hole II are arranged, the left end hole internal diameter that pipe 2 is put in the maximum gauge of end socket and expansion coincide, core bar 5 has certain elasticity, it is much smaller that its diameter is put pipe 2 interior diameters than expansion, core bar 5 rear portions have the directed wing 8, and the following directed wing 8 has a wing sheath that just in time coincide with circular hole II, the core bar 5 outer pipe closes 7 that can move freely that are with, pipe close 7 overall diameters and expansion are put pipe 2 interior diameters and are coincide, pipe close 7 is provided with one and forms the spring locking device by plug sheath and spring 6, pipe close 7 stop up expand put pipe 2 right-hand member holes after, can prevent and treat liquid spray leakage, the spring locking device can be prevented deviating from after detent plug sheath and the circular hole I locking, and plug sheath and circular hole I prevent that with lock pipe close 7 from deviating from.

1., the anaesthetic and the lubricant drop that are injected by short side pipe 3 can not spill, and realizes painless urethral catheterization and painless dilation of urethra when this utility model is used for urethra urethral catheterization or urethral dilatation; 2. in various serious component difficulties big urethral catheterization and dilation of urethra, the liquid outlet of being put the pipe left end by expansion can flow out urine, promptly knows and successfully inserts bladder, thereby avoid blindly operation and the damage bladder; 3. when the dilation of urethra success, can realize that to bladder and urethra injection contrast agent the full urethra of bladder is contrary along two-way radiography new technique by short side pipe 3 simultaneously, the narrow morphology of various complicated pathology comes into plain view, for intubate urethral catheterization later on or dilation procedure provide reliable guidance reference; 4. inject the antibiotics prevention infection by short side pipe 3 to bladder in the art, expand and put conical tip shape end socket 1 assembling of pipe 2 with its same specification, the multi-functional expansion stereotactic puncture that makes this utility model become a kind of front curvature is again put pipe.
