Abstract
The invention discloses an anti-bending pigtail catheter which comprises a catheter body, wherein the catheter body comprises a catheter tube body and a guide wire penetrating through the catheter tube body, the guide wire comprises a core wire and a winding sleeve, the catheter tube body is made of plastic materials with shape memory, the winding sleeve is formed by spiral winding wires which are arranged in an overlapping mode, the core wire is made of shape memory materials, the core wire can still keep a better original state after being bent for many times, the catheter can still keep a conducting state under the bending condition through the spiral winding sleeve, and medical accidents are prevented.
Description
Technical field
The present invention relates to a kind of anti-discounting pigtail catheter be used as on clinical medicine.
Background technology
Pigtail catheter, because of butt curl, often end is similar to pigtail and gains the name.Due to its support and interior drainage, ureter inflammation can be removed, transient obstruction that edema causes, prevent postoperative wound leakage of urine and stricture of ureter.Meanwhile, aggregation system does not directly communicate with the external world, can avoid hemorrhage, infection caused by kidney fistulation; Because of without the restriction of drainage tube and sense of discomfort, patient can early ambulation, favourable postoperative rehabilitation, but in actual use, due to ureter non-straight spool, the situation of the blocking therefore giving a discount easily appears in conduit.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of anti-discounting pigtail catheter.
The technical solution adopted for the present invention to solve the technical problems is:
Anti-discounting pigtail catheter, comprise catheter body, described catheter body comprises catheter tube and is located in the seal wire in catheter tube, described seal wire comprises stamen silk and coiling cover, described catheter tube is made by there being the plastic material of shape memory, described stamen silk is made up of shape-memory material, and described coiling cover is formed by the spiral wrapping wire of stacked arrangement.
Described catheter tube is made up of medical silica-gel material.
Described stamen silk is made up of Nitinol.
Described coiling cover is formed by the helical form steel wire of stacked arrangement.
Described stamen silk is made up of the filament of many.
The invention has the beneficial effects as follows: anti-discounting pigtail catheter, comprise catheter body, described catheter body comprises catheter tube and is located in the seal wire in catheter tube, described seal wire comprises stamen silk and coiling cover, described catheter tube is made by there being the plastic material of shape memory, described coiling cover is formed by the spiral wrapping wire of stacked arrangement, described stamen silk is made up of shape-memory material, make stamen silk still can keep preferably initial condition after repeatedly bending, and still can keep conducting state under making conduit situation on sale by spiral helicine coiling cover, prevent the generation of malpractice.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is structural representation of the present invention;
Fig. 2 is generalized section of the present invention.
Detailed description of the invention
With reference to Fig. 1, Fig. 2, Fig. 1, Fig. 2 is the structural representation of the present invention's specific embodiment, as shown in the figure, anti-discounting pigtail catheter, comprise catheter body, the seal wire that described catheter body comprises catheter tube 1 and is located in catheter tube 1, described seal wire comprises stamen silk 2 and coiling cover 3, described catheter tube 1 is made by there being the plastic material of shape memory such as medical silica-gel material, described coiling cover 3 is formed by the spiral wrapping wire of stacked arrangement, described stamen silk 2 by shape-memory material as Nitinol is made, make stamen silk 2 still can keep preferably initial condition after repeatedly bending, reduce when seal wire is walked or the resistance in the time of extracting, reduce the injury to blood vessel and tissue, reduce the misery of patient, and still can keep conducting state under making conduit situation on sale by spiral helicine coiling cover 3, prevent the generation of malpractice.
As preferably, in the present embodiment, described catheter tube 1 is made up of medical silica-gel material, described coiling cover 3 is formed by the helical form steel wire of stacked arrangement, there is provided certain support force can to catheter tube 1 tube wall by this helical form steel wire, under lateral pressure, catheter tube 1 still can be made to keep conducting state, can effectively prevent conduit to be extruded and narrow and block, improve its safety.
Above better enforcement of the present invention is illustrated; certainly; the present invention can also adopt form different from the embodiment described above; as stamen silk 2 can be combined into by the filament of many; its shape memory restorability of further raising; the equivalent conversion that those of ordinary skill in the art do under the prerequisite without prejudice to spirit of the present invention or change accordingly, all should belong in protection scope of the present invention.
