Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the sectional structure sketch map shown in the I among Fig. 1.
Fig. 3 is the sectional structure sketch map shown in the II among Fig. 1, and this moment, plug was placed in the containing section of conduit.
Fig. 4 is the unfolded first kind of structural representation of plug among Fig. 3.
Fig. 5 is the unfolded second kind of structural representation of plug among Fig. 3.
Fig. 6-Fig. 8 is this utility model compression process sketch map.
Among the figure: 1 seal wire, 11 traction sections, 12 lead segment, 111 positioning convex, 2 conduits, 3 adapter sleeves, 22 contain section, the groove of 31 city wall shapes, 4 plugs.
The specific embodiment
As shown in Figure 1-Figure 3, the ureter plugging device comprises conduit 2, is provided with seal wire 1 in the conduit 2, and seal wire 1 comprises traction section 11 and lead segment 12.Seal wire 1 is provided with near lead segment 12 places can be by the plug 4 of axial compression, and axial compression is folded into bolt shape thing, thereby plays the effect of shutoff ureter tube chamber.Conduit 2 is provided with lead segment 12 respective end and contains section 22, contains section 22 and forms ccontaining cavity with seal wire 1.Under the original state, plug 4 is compressive state and is positioned at this ccontaining cavity.An end that contains section 22 close lead segment 12 is the elasticity throat structure, stretch out from containing in the section 22 so that seal wire 1 can drive plug 4, and when behind seal wire 1, taking out, can stop plug 4 to enter and contain in the section 22, prevent and can not form bolt shape thing, realize the ureter shutoff.
This utility model under the original state, is placed in the containing section 22 of conduit 2 with plug 4, can make plug 4 under the small size state of compression, is easier to arrive the calculus near-end by calculus, realizes the ureter shutoff.
As further improvement of the utility model, conduit 2 is provided with adapter sleeve 3 with traction section 11 respective end.Adapter sleeve 3 is a tubular structure, and seal wire 1 is positioned at it.The corresponding position of adapter sleeve 3 and conduit 2 is provided with the annular joggle portion that matches, and realizes not only that adapter sleeve 3 rotates with conduit 2 to connect, and defines the axial location of adapter sleeve 3 and conduit 2.Adapter sleeve 3 has the groove 31 of the city wall shape of extending vertically, and seal wire 1 is provided with the positioning convex 111 that is arranged in groove 31.Along with moving of seal wire 1, positioning convex 111 moves in the long strip type passage of this groove 31, and as requested, and the cover 3 that is rotationally connected makes positioning convex 111 be positioned at the depressed part of groove 31, to realize the axial location of seal wire 1.The position location of the number of the depressed part of groove 31 and seal wire 1 is corresponding, therefore, as Fig. 6-shown in Figure 8, can realize that plug 4 realizes the bolt shape things of different sizes according to different needs.
