Embodiment
The embodiment of the present invention is described in detail with specific embodiment mode below in conjunction with the accompanying drawings.
As shown in Fig. 2 be a kind of structural representation of double J pipe extractor provided in an embodiment of the present invention, including the He of conduit 2
Seal wire 3 is extracted, seal wire 3 is extracted and is arranged in conduit 2, and extracts the both ends of the extended conduit 2 of seal wire 3, extracts seal wire 3 as closing
Annular seal wire, for extracting double J pipe 1, conduit 2 is played a supporting role, and is extracted the per urethra of seal wire 3 for assistance and is stretched into bladder.
It is not directly to be alignd with urethral orifice further, since being located at the side of bladder after the implantation bladder of double J pipe 1, and commonly uses
Mondet forceps be straight configuration, need rotation direction to grip double J pipe in bladder, but the operation can make to patient
Into pain.Therefore, one end of conduit 2 is bent and set, be easy to use the guiding of conduit 2 to extract seal wire 3 and extract double J pipe, bending
Angle is usually 25-35 degree according to actual conditions, preferably 30 degree, and the length of bent portion may be configured as 3-7 millimeters, preferably 5 millis
Rice.
Silica gel may be selected in the material of conduit 2, soft texture, is not easy that urethra is caused to damage, its length and diameter may be selected
6Fr, 8Fr, 10Fr, 12Fr, 14Fr, 16Fr and 18Fr equidimension.Extract seal wire 3 may be selected material it is harder, have certain toughness,
The strong high polymer material of chemical stability, and available sharp instrument is cut, and is easy to the closed-loop of adjustment stretching conduit 2 one end when extracting
The size of shape.
When extracting double J pipe, if no urine is saved in bladder, then bladder can shrink, and intravesical space diminishes,
It is unfavorable for covering extract operation, therefore, a certain amount of liquid can be filled with into bladder, makes filling of bladder.Therefore in the side of the other end of conduit 2
Wall opens up water filling port 4, and water filling port 4 is extended to outside conduit 2, and water filling port 4 is provided with plug 5.Need to be filled with liquid into bladder (such as
Physiological saline) when, plug 5 is opened, water filling port 4 is connected with injector or other water filling devices, filled by conduit 2 into bladder
Water, make filling of bladder, be easy to extract double J pipe and observed under color ultrasound.
In order to ensure intravesical urine or it is above-mentioned be filled with intravesical liquid will not with conduit 2 the other end flow out, together
When enable to extract the both ends that seal wire 3 frees in and out conduit 2, the structure of the other end of conduit 2 is optimized.
A concave surface is recessed into the end face of the other end of conduit 2, concave surface offers the through hole for extracting the stretching of seal wire 3, and through hole
Diameter match with extracting the diameter of seal wire, concave shape can be cone, infundibulate or other shapes, not limit herein
It is fixed.
Further, it is also possible to set soft stopple 6 in the other end of conduit 2, soft stopple 6 is arranged to cone, it is logical to extract seal wire 3
The hole crossed at the soft center of stopple 6 is stretched out, and the aperture of soft stopple 6 matches with extracting the diameter of seal wire 3.Extract seal wire 3 and extract double J
After pipe 1, pull on extract seal wire 3 make double J pipe 1 enter conduit 2 in, now if necessary to by double J pipe 1 through being taken out in conduit 2,
Soft stopple 6 can be then removed, and then takes out double J pipe 1.
Extract after seal wire 3 extracts double J pipe 1, when double J pipe 1 is pulled in conduit 2, because one end that double J pipe 1 is extracted is
Coiled structure, if the crimping portion of double J pipe 1 is oversized when extracting, then even if conduit 2 is made of soft material,
Double J pipe 1 can not can be pulled in conduit 2 because of the oversized of the crimping portion of double J pipe 1, therefore, as shown in figure 3, being this hair
A kind of structural representation of the port for double J pipe extractor curved end that bright embodiment provides, the port that conduit 2 bends one end are set
There are at least two arc notch 7, be easy to further expand the port of conduit 2, be easy to use and extract seal wire 3 and pull in double J pipe.
From the above mentioned, double J pipe 1 is implanted into after bladder positioned at the side of bladder, is not directly to be alignd with urethral orifice, therefore adopt
When extracting double J pipe 1 with double J pipe extractor provided in an embodiment of the present invention, can under the guide of colorful Doppler ultrasound diagnostic apparatus,
Determine to extract the optimum position of double J pipe 1 by rotary guide pipe 2 and the length that stretches into of adjustment conduit 2, for the ease of to rotation
Angle and the length stretched into are measured, as shown in figure 4, the structural representation for conduit provided in an embodiment of the present invention and mark line
Figure, it is provided with along the outer wall of the length direction of conduit 2 for measuring length and/or illustrating the mark line 8 of the anglec of rotation of conduit 2, mark
Note line 8 can be arranged on the outer wall of conduit 2 backwards to the side of bent portion, can also be arranged on the outer wall of conduit 2 towards bent portion
Side, especially, the outer wall of conduit 2 backwards to and both sides towards bent portion be provided with mark line 8, mark line 8 uses
Chequered with black and white scale, and every 5 centimetres set a kind of mark of other colors, are easy to further determine that the length that conduit 2 stretches into.
Using extracting when seal wire 3 extracts double J pipe 1, it is necessary to adjust the dynamics that pulls double J pipe 1 according to the actual impression of patient,
Therefore, an annulus 9 for being used to hook up is connected with one end for extracting seal wire 3 away from the bent portion of conduit 2, for connecting spring
Scale or other devices for being used to measure pulling force, in real time monitoring pull the dynamics of double J pipe 1.
During practical operation, double J pipe extractor curved end provided in an embodiment of the present invention is stretched into patient's urethra, in colour
Under the guide of Doppler ultrasonic diagnosis apparatus, curved end port and the position of double J pipe, the port then through the curved end of conduit 2 are adjusted
Stretching extracts seal wire 3 and extracts double J pipe, and double J pipe is pulled in conduit 2, is unfavorable for extracting if space is smaller in bladder, opens
Water filling port 4 on conduit 2, it is filled with after physiological saline makes filling of bladder and extracts double J pipe, finally conduit 2 is exited and completes to take out
The operation of double J pipe.
In summary, a kind of double J pipe extractor provided by the invention is using the structure that seal wire is extracted built in conduit, by leading
Pipe stretches into urethra, extracts seal wire and extracts double J pipe, substitute cystourethroscope and mondet forceps, reduces apparatus volume, and extract
Mode is low compared to the mode fault rate of gripping, can effectively shorten the time for taking double J pipe to expend, and mitigates patient's pain, reduces
Cost.
