Abstract
The utility model discloses a hard tip type pigtail-shaped flow guiding catheter which comprises a straight catheter body and a bending catheter body. A tip portion is arranged at the end portion of the bending catheter body, a female joint is arranged at the end portion of the straight catheter body, the tip portion is in a wedge shape, and the hardness of the tip portion is larger than that of the bending catheter body and that of the straight catheter body. The hard tip type pigtail-shaped flow guiding catheter has the advantages of increasing penetrating power, being smoother in indwelling the catheter, improving security, reducing probability of accidentally injuring a visceral organ of a patient, and effectively shortening time of a catheter indwelling surgery.
Description
Technical field
This utility model relates to technical field of medical instruments, especially relates to a kind of hard tip-type pigtail drainage catheter.
Background technology
Pigtail drainage catheter percutaneous puncture of the prior art is progressively minimally invasive hole to be expanded to required size by the method that puncture is expanded, enter lesions position by seal wire guiding pigtail drainage catheter again, catheter proximal end is processed into the wedge shape of tapering, so that enter in the human body by expanded bore, the wedge shaped tip of existing conduit is to have added the soft material of holding material or the equal hardness of body directly to form by Mould Machining, because material high resilience and the softness of catheter tube itself, catheter proximal end enters into the thoracic cavity by seal wire, the abdominal cavity, renal pelvis, when intravesical or certain lesions position, because the resistance that is subjected to people's human body can make the most advanced and sophisticated distortion of the wedge of conduit or rive to cause and put the pipe difficulty, if too soft too thin the making of wedge shaped tip may be caused the most advanced and sophisticated clot of wedge or broken in itself and the seal wire friction process, the most advanced and sophisticated burr that produces of wedge, may cause the accidental injury to internal organs, in addition, the drainage catheter that also has a kind of hard in the prior art, its wedge shaped tip and body all are hard material, though solved the penetration power that conduit enters human body, but because whole conduit quality is too hard, insert people's cognition sufferer is caused serious discomfort, medical personnel's spirit high-pressure when operation also easily produces tired, may cause the consequence serious to sufferer during maloperation.
The utility model content
Technical problem to be solved in the utility model is: a kind of hard tip-type pigtail drainage catheter is provided, strengthens its penetration power, it is more smooth to put pipe, has improved safety, has reduced the probability that patient's internal organs are accidentally injured, and has effectively shortened the time of putting the pipe operation.
For solving the problems of the technologies described above, the technical solution of the utility model is: hard tip-type pigtail drainage catheter, comprise linear conduit body and bending conduit body, the end of described bending conduit body is provided with point, the end of described linear conduit body is provided with female joint, described point is wedge shape, and the hardness of described point is greater than the hardness of described bending conduit body and linear conduit body.
Preferably, it is the TPU developing material of 60D-65D that described point adopts shore hardness, and it is the TPU developing material of 85A-100A that described bending conduit body and linear conduit body all adopt shore hardness.
Preferably, the wedge angle of described point is less than 30 degree.
Adopted technique scheme, the beneficial effects of the utility model are: because the point of hard tip-type pigtail drainage catheter is wedge shape, the hardness of point is greater than the hardness of bending conduit body and linear conduit body, fuse together by the material of hot briquetting equipment with two kinds of different hardness, make the tip portion of pigtail drainage catheter have enough penetration powers, the puncture and intubation operation of pigtail drainage catheter can be finished more smoothly, improved safety, reduce the probability that patient's internal organs are accidentally injured, and effectively shortened the time of putting the pipe operation.
Description of drawings
Fig. 1 is the structural representation of this utility model embodiment;
Wherein: 1, linear conduit body; 2, bending conduit body; 3, point; 4, female joint.
The specific embodiment
Below in conjunction with drawings and Examples this utility model is further specified.
As shown in Figure 1, hard tip-type pigtail drainage catheter, comprise linear conduit body 1 and bending conduit body 2, the end of bending conduit body 1 is provided with point 3, the end of linear conduit body 1 is provided with female joint 4, point 3 is wedge shape, and the hardness of point 3 is greater than the hardness of bending conduit body 2 and linear conduit body 1.
In the present embodiment, it is the TPU developing material of 60D-65D that point 3 adopts shore hardness, and it is the TPU developing material of 85A-100A that bending conduit body 2 and linear conduit body 1 all adopt shore hardness.
In addition, the wedge angle of point 3 is conducive to put smoothly pipe less than 30 degree.
This utility model fuses together by the material of hot briquetting equipment with two kinds of different hardness, make the point 3 of pigtail drainage catheter have enough penetration powers, the puncture and intubation operation of pigtail drainage catheter can be finished more smoothly, improved safety, reduce the probability that patient's internal organs are accidentally injured, and effectively shortened the time of putting the pipe operation.
This utility model is not limited to above-mentioned concrete embodiment, and those of ordinary skill in the art is from above-mentioned design, and without performing creative labour, all conversion of having done all drop within the protection domain of the present utility model.
