Abstract
The utility model provides a drainage catheter which comprises a catheter body and a pigtail-shaped ring located at one end of the catheter body. The pigtail-shaped ring is curled in a spiral shape, the pigtail-shaped ring and the catheter are not located on a same plane, and the tail end of the pigtail-shaped ring comprises a straight end portion and a pointed end portion formed by the straight end portion in an extending mode. The pigtail-shaped ring is curled in the spiral shape, the pigtail-shaped ring and the catheter are not located on the same plane, and the drainage catheter is made not to be prone to slipping. In addition, the tail end of the pigtail-shaped ring is straight, the drainage catheter can be smoothly implanted in a human body when a doctor operates on a patient, and the pain of the patient is reduced. Furthermore, the pointed end of the pigtail-shaped ring is arranged to be straight, the implantation time of the drainage catheter is shortened, and clinical operation efficiency is improved.
Description
Technical field
This utility model relates to a kind of drainage catheter, relates in particular to a kind of drainage catheter with pigtail circle of helix-coil.
Background technology
Ureter obstruction, pneumothorax, hemothorax, hydrothorax, bile surplus when health self can't normally be discharged hydrops, need to use drainage catheter to set up passage, carry out the discharge opeing treatment fast and effectively.Existing pigtail type drainage catheter, pigtail circle and drain body are all on a plane, and the most advanced and sophisticated place of pigtail circle is curved shape.
As shown in Figure 1, be traditional drainage catheter 20, comprise body 21 and pigtail circle 22 altogether.Pigtail circle 22 has a tip 23, and pigtail circle 22 is fixed to circle or two circles usually.Most advanced and sophisticated 23 usually as the arcuate end of whole pigtail circle 22 1 circles, are curved shape or warped shapes naturally, be and stick up tail, yet that implant when the doctor performs the operation at the tip 23 of this curved shape is obstructed.Even when operation, smooth out with the fingers straight tip, but can cause the drainage catheter implantation time long, and, even smoothing out with the fingers directly also can restore, the tip is certain warped shapes, make troubles to implantation.
The utility model content
In view of this, this utility model provides a kind of drainage catheter that can smooth and easyly implant.
A kind of drainage catheter, the pigtail circle that it comprises body and is positioned at body one end, described pigtail circle shape in the shape of a spiral curls, and described pigtail circle and described body be not in same plane, and the end of described pigtail circle comprises straight end parts and the tip portion that is extended by straight end parts.
Preferably, described pigtail circle begins helix-coil from the end of described body.
Preferably, described pigtail circle helix-coil 180 degree are to 720 degree.
Preferably, described pigtail circle raised shape in the shape of a spiral.
Preferably, the downward projection of described pigtail circle is circular, faces and is projected as " S " or " Z " shape.
Preferably, the wall circle inboard of described pigtail circle has a plurality of through holes of arranging along self bearing of trend.
Preferably, the length of the straight end parts of described pigtail circle is 1/10 to 1/6 of whole pigtail circle length.
Preferably, the length ratio of described straight end parts and tip portion is 2-3: 1.
Preferably, described tip portion is the tack taper.
In the above-mentioned drainage catheter, pigtail circle shape in the shape of a spiral curls, and itself and body be not or not same plane, and the end of pigtail circle comprises straight end parts and tip portion, and namely the end of pigtail circle is flat end, thereby when the doctor performs the operation, can be implanted in swimmingly in the human body, alleviate patient's pain.Further, make straight type at pigtail circle tip, shortened drainage catheter and implanted the time, improved clinical operation efficient.

The specific embodiment
Below with reference to the drawings and the specific embodiments this utility model is elaborated.
See also Fig. 1 to Fig. 4, this utility model embodiment provides a kind of drainage catheter 10, the pigtail circle 13 that it comprises body 11 and is positioned at body 11 1 ends, pigtail circle 13 shape in the shape of a spiral curls, pigtail circle 13 and body 11 be not in same plane, and the end of pigtail circle 13 comprises straight end parts 14 and the tip portion 15 that is extended by straight end parts 14.In the present embodiment, body 11 is made by the PU material.
Particularly, as shown in the figure, pigtail circle 13 begins helix-coil from the end of body 11.Further, pigtail circle 13 helix-coils 180 degree are to 720 degree, that is, from depression angle shown in Figure 3, pigtail circle 13 helix-coil half-turns to two enclose.In the present embodiment, pigtail circle 13 helix-coils one circle, pigtail circle 13 and described body 11 are formed in one, and pigtail circle 13 is directly formed by curling 360 degree of the end convolution of body 11.Certainly, be not limited to present embodiment, pigtail circle 13 and body 11 also can be distinguished molding, and pigtail circle 13 also can helix-coil 180 degree, 270 degree or 720 degree etc.
As shown in Figure 2, pigtail circle 13 raised shape in the shape of a spiral.As shown in Figure 3, the downward projection of pigtail circle 13 is circular, faces and is projected as " S " or " Z " shape (as shown in Figure 2).The wall circle inboard of pigtail circle 13 has a plurality of through holes 16 of arranging along self bearing of trend, is beneficial to drain.
As shown in Figure 3, the length L 1 of straight end parts 14 is 1/10 to 1/6 of whole pigtail circle length.The ratio of the length L 1 of straight end parts 14 and the length L 2 of tip portion 15 is 2-3: 1.Tip portion 15 is preferably the tack taper, and is preferably smooth ends.Because end be directly to hold, thereby in medical operation, during the described drainage catheter 10 of use, can be implanted in swimmingly in the human body, can effectively reduce the damage of surrounding tissue, alleviate patient's pain.
Therefore, in the above-mentioned drainage catheter 10, by the end of pigtail circle is made flat shape, thereby when the doctor performs the operation, can be implanted in swimmingly in the human body, alleviate patient's pain.Further, make straight type at pigtail circle tip, shortened the 10 implantation times of drainage catheter, improved clinical operation efficient.And pigtail circle 13 and body 11 have strengthened the contact area between pigtail circle and tissue not in same plane, increase frictional force, and it is external to prevent effectively that pigtail type drainage catheter from skidding off, the grip when increasing drainage catheter 10 implantation.
Need to prove; this utility model is not limited to above-mentioned embodiment; according to creative spirit of the present utility model; those skilled in the art can also make other variations; these all should be included within this utility model scope required for protection according to the variation that creative spirit of the present utility model is done.
