Abstract
The utility model discloses a retainable anal fistula radiography catheter, which is characterized by comprising a soft catheter, a Y-shaped injection catheter arranged on the soft catheter and a hard needle core matched with the soft catheter; the front end of the soft catheter is uniformly provided with a plurality of injection side holes. The utility model can keep in place for a long time by the soft catheter through the arrangement of the soft catheter, thereby being convenient for the injection positioning again in the operation, having stable operation and being not easy to shift; through the arrangement of the Y-shaped injection catheter, the injection is respectively injected from the related injection tubes through the Y-shaped injection catheter, so that the accurate diagnosis of an ultrasonic doctor before an operation and the accurate positioning and excision in the operation of a clinician are conveniently improved; by the arrangement of the injection side hole, the injection liquid is uniformly distributed in front of and behind the fistula as much as possible by utilizing the injection side hole, thereby improving the contrast effect and the injection speed.
Description
Technical Field
The utility model relates to an anal fistula radiography technical field specifically indicates an anal fistula radiography pipe that can keep somewhere.
Background
Some stealthy fistula or tiny fistula can not accurately be detected in current rectum imaging inspection, in order to look for the position of perianal abscess patient fistula way as far as possible, quantity, make things convenient for the clinician accurate, radical excision, reduce the relapse, fistula radiography under using the supersound guide usually is applied to clinically, in the prior art, the pjncture needle is mostly ordinary vein and is kept somewhere needle or PTC needle on the market, but ordinary needle length of keeping somewhere is not enough, the PTC needle is not only longer and the needle tubing is harder, easily take off the fistula, lead to fistula radiography failure, and this type of pjncture needle all does not have the side opening, lead to annotating the medicine in-process, the injection rate is slow, the involved scope is narrow, make some tiny fistulas far-end fistulas a result of the contrast medium not enough effective development, the accuracy of location excision in the clinician art has been reduced. Therefore, the indwelling anal fistula angiography catheter is provided.
Disclosure of Invention
The utility model aims at providing a indwelling anal fistula radiography catheter for solving the problems.
In order to achieve the above purpose, the utility model provides a following technical scheme: a kind of anal fistula radiography conduit that can be kept, characterized by including the soft conduit, Y-type injection conduit that is set in soft conduit and hard stylet used in coordination with soft conduit; the front end of the soft catheter is uniformly provided with a plurality of injection side holes.
Preferably, the Y-shaped injection catheter comprises an injection extension tube A and an injection extension tube B which are respectively arranged on the soft catheter; and the injection extension pipe A and the injection extension pipe B are both provided with a single-hand clamp.
Preferably, the tail part of the soft conduit is also provided with a soft rubber block.
The utility model has the advantages that: through the arrangement of the soft catheter, the soft catheter can be used for indwelling for a long time, so that the secondary injection positioning in the operation is facilitated, the operation is stable, and the displacement is not easy;
through the arrangement of the Y-shaped injection catheter, the injection is respectively injected from the related injection tubes through the Y-shaped injection catheter, so that the accurate diagnosis of an ultrasonic doctor before an operation and the accurate positioning and excision in the operation of a clinician are conveniently improved;
through the arrangement of the injection side hole, the injection liquid is uniformly distributed before and after the fistula as much as possible by utilizing the injection side hole, thereby improving the contrast effect and the injection speed.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a partial sectional view of the present invention.
Illustration of the drawings: 1, a soft catheter; 101, a soft rubber block; a 2Y-shaped injection catheter; 201 injecting an extension tube A; 202 injecting an extension tube B; 203, clamping with a single hand; 3, hard needle core; 4 side injection hole.
Detailed Description
The following will further describe a indwelling anal fistula angiography catheter according to the present invention with reference to the accompanying drawings.
Referring to the attached drawings 1-2, the indwelling anal fistula angiography catheter is characterized by comprising a soft catheter 1, a Y-shaped injection catheter 2 arranged on the soft catheter 1 and a hard needle core 3 matched with the soft catheter 1; a plurality of injection side holes 4 are uniformly arranged at the front end of the soft catheter 1; through the arrangement of the soft catheter 1, the soft catheter 1 can be used for indwelling for a long time, so that the re-injection positioning in the operation is facilitated, the operation is stable, and the displacement is not easy to occur; through the arrangement of the Y-shaped injection catheter 2, the Y-shaped injection catheter 2 is used for injecting the injection from the related injection pipes respectively, so that the accurate diagnosis of preoperative ultrasonic doctors and the accurate positioning excision of clinicians in the operation are improved conveniently; by arranging the injection side hole 4, the injection liquid is distributed as uniformly as possible before and after the fistula by using the injection side hole 4, thereby improving the contrast effect and the injection speed.
Referring to fig. 1-2, the Y-shaped injection catheter 2 includes an injection extension tube a201 and an injection extension tube B202 respectively provided on the flexible catheter 1; the injection extension pipe A201 and the injection extension pipe B202 are both provided with a single-hand clamp 203; the tail part of the soft catheter 1 is also provided with a soft rubber block 101 through interference fit; through the arrangement of the soft rubber block 101 at the tail part of the soft catheter 1, the soft rubber block 101 can be automatically closed after the hard needle core 3 is pulled out, so that the sealing property of the soft catheter 1 is improved; the injection extension tube A201 and the injection extension tube B202 are used for respectively injecting SonoVue sulfur hexafluoride (SF 6) and methylene blue injection, so that accurate guiding and positioning and accurate cutting in the operation of a clinician are improved.
The utility model discloses a use, at first puncture to the fistula under the soft catheter 1 who installs hard nook closing member 3 through the supersound guide, then pull out hard nook closing member 3 backward, flexible glue piece 101 department pulls out behind the hard nook closing member 3 self-sealing, thereby keep in soft catheter 1 in the fistula, be used for fistula radiography and fistula dyeing, then open injection extension pipe A201 through one-hand clamp 203, injection extension pipe B202 is closed, inject sulfur hexafluoride diluent in injection extension pipe A201 department, sulfur hexafluoride diluent gets into the fistula through injection side opening 4 on soft catheter 1 and the soft catheter 1, evenly distributed is around the fistula, carry out the radiography to the fistula, after the radiography is accomplished, close injection extension pipe A201 through one-hand clamp 203, injection extension pipe B202 is opened, then pour into methylene blue injection in injection extension pipe B202 department, methylene blue injection gets into the fistula through injection side opening 4 on soft catheter 1 and the soft catheter 1 of supersound guide, positioning for surgical resection.
The above-mentioned embodiment is right the utility model discloses an explanation, it is not right the utility model discloses a limited, any is right the utility model discloses scheme after simply changing all belongs to the protection scope of the utility model.
