Description

T-type drainage tube

Technical field

The utility model relates to drainage tube field more particularly to a kind of T-type drainage tubes.

Background technique

T-type drainage tube is the rubber tube that a kind of shape is T shape, including extension tube attached and two bifurcated pipes.As shown in figure 4, gallbladder After road operation, two bifurcated pipes are placed in choledochus, extension tube attached are connected into drainage bag, thus bile drainage.The merging of T-type drainage tube The operation of choledochus is specifically: firstly, carrying out the cutting of length direction to bifurcated pipe, so that it is of convenient length, can also carry out axial direction Subdivision makes it easy to be put into choledochus；Then, a bifurcated pipe is put into choledochus from the notch on choledochus, then by another Bifurcated pipe is put into choledochus from the notch on choledochus.Obviously, two bifurcated pipes can not once-through operation be put into choledochus simultaneously, make Bifurcated pipe be put into operation it is more troublesome.

Utility model content

Technical problem to be solved by the utility model is: providing a kind of T-type drainage that can simplify merging choledochus operation Pipe.

In order to solve the above problem the technical solution adopted is that: T-type drainage tube includes drainage tube main body, and drainage tube main body includes Extension tube attached and two bifurcated pipes, it is characterised in that: including guide wire；There are two tube walls to press from both sides for connection in the tube wall of drainage tube main body Layer forms guidance wire hole between tube wall interlayer and the tube wall of drainage tube main body；One guidance wire hole is extended to by external tube end In one bifurcated pipe, another guidance wire hole is extended in another bifurcated pipe by external tube end；Distinguish position in guide wire both ends In in two guidance wire holes, guide wire can be moved along guidance wire hole, and guide wire includes the modeling of two linears positioned at both ends Shape section and the compliant section between two moulding sections.

Further, moulding section includes the plastic outer layer of steel wire internal layer and wrapped wire internal layer.

Further, being provided with trimming home label and guide wire hole location tagging on bifurcated pipe, wire hole is guided Position mark is corresponding with the guidance end position of wire hole, and trimming home label is located on the outside of guide wire hole location tagging.

The beneficial effects of the utility model are: the utility model T-type drainage tube be placed in biliary tract when, first as shown in figure 3, to Interpolation guide wire makes guide wire reach guidance wire hole bottom hole, and due to the effect of moulding section, bifurcated pipe bending, T-type drainage tube is in straight It is linear；Fork tube end is put into choledochus from the notch on choledochus again；Hold bifurcated pipe on the other hand again, slowly extraction is drawn on the other hand Seal wire, bifurcated pipe are extend into choledochus because natural resiliency resets；Guide wire extraction, bifurcated pipe reset after, T-type drainage tube with Existing T-type drainage tube homomorphosis.It can be seen that two bifurcated pipes can be placed in choledochus, Neng Goujian by the utility model once-through operation Change merging choledochus operation.

Detailed description of the invention

In the figure, it is marked as drainage tube main body 1, extension tube attached 11, bifurcated pipe 12, tube wall interlayer 13, guidance wire hole 14, thread eye Position mark 15, trimming home label 16, guide wire 2, moulding section 21, compliant section 22, choledochus 3.

Specific embodiment

The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

It is shown as depicted in figs. 1 and 2: T-type in order to provide a kind of T-type drainage tube that can simplify merging choledochus operation Drainage tube includes drainage tube main body 1, and drainage tube main body 1 includes extension tube attached 11 and two bifurcated pipes 12, it is characterised in that: including drawing Seal wire 2；Connection is there are two tube wall interlayer 13 in the tube wall of drainage tube main body 1, the tube wall of tube wall interlayer 13 and drainage tube main body 1 it Between formed guidance wire hole 14；One guidance wire hole 14 is extended in a bifurcated pipe 12 by 11 end of extension tube attached, another guidance Wire hole 14 is extended in another bifurcated pipe 12 by 11 end of extension tube attached；2 both ends of guide wire are located at two guidance wire holes 14 Interior, guide wire 2 can be moved along guidance wire hole 14, and guide wire 2 includes moulding section 21 and the position of two linears positioned at both ends Compliant section 22 between two moulding sections 21.

When the T-type drainage tube of the utility model is placed in biliary tract, first as shown in figure 3, stretching guide wire 2 to interpolation guide wire 2 To guidance 14 bottom hole of wire hole, due to the effect of moulding section 21, bifurcated pipe 12 is bent, and T-type drainage tube is linear；Again by bifurcated pipe 12 ends are put into choledochus 3 from the notch on choledochus 3；It holds bifurcated pipe 12 on the other hand again, slowly extracts guide wire 2 out on the other hand, point Bifurcated pipe 12 is extend into choledochus 3 because natural resiliency resets；Guide wire 2 extract out, bifurcated pipe 12 reset after, T-type drainage tube with Existing T-type drainage tube homomorphosis.

The effect of moulding section 21 is to keep the bending of bifurcated pipe 12 linear to entire T-type drainage tube when guide wire 2 is inserted into Type, therefore moulding section 21 should have certain rigidity, when guide wire 2 is inserted into guidance 14 bottom hole of wire hole, moulding section 21 should have portion Fractionation is in extension tube attached 11.When guide wire 2 is extracted out, compliant section 22 is drawn.

Tube wall interlayer 13 is pierced through in order to avoid drawing moulding section 21, moulding section 21 includes steel wire internal layer and wrapped wire internal layer Plastic outer layer.Steel wire internal layer makes moulding section 21 have suitable rigidity, and it is excessively sharp that plastic outer layer can avoid 21 end of moulding section Sharp puncture tube wall interlayer 13.

As stated in the background art, bifurcated pipe 12 needs to cut, in order to avoid cutting tube wall interlayer 13, bifurcated pipe 12 when cutting On be provided with trimming home label 16 and guide wire hole location tagging 15, guide wire hole location tagging 15 and guidance wire hole 14 End position it is corresponding, trimming home label 16 is located on the outside of guide wire hole location tagging 15.Peace is only pruned when trimming 16 exterior portion of all positon label can avoid cutting tube wall interlayer 13.
