Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

In the description of the present invention, "a plurality" means two or more unless otherwise specified. For a scheme with a time sequence flow, the term expression does not need to be understood as describing a specific sequence or a sequence order, and for a scheme of a device structure, the term expression does not have distinction of importance degree, position relation and the like.

Furthermore, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements specifically listed, but may include other steps or elements not expressly listed that are inherent to such process, method, article, or apparatus or that are added to such process, method, article, or apparatus based on the concepts of the present invention.

As shown in fig. 1, 2 and 3, for the utility model discloses a puncture card for guiding fistulization of a bladder 5, including pricking a card core 1 and pricking a card sheath 2, the diameter of the card sheath 2 is 10, a drainage tube capable of placing F18-F20 can be placed, both ends of the card sheath 2 are arranged in a penetrating manner, the card core 1 is inserted from the top end of the card sheath 2 and penetrates out from the bottom end of the card sheath 2, the card core 1 penetrates out from the bottom end of the card sheath 2 by 2mm, a hollow pipeline 3 penetrating through both ends is arranged along the axial direction of the card core 1, the diameter of the hollow pipeline 3 is 2mm, and a guide wire 4 with the diameter of 1mm is placed;

the part of the poking and clamping core 1 penetrating out of the bottom end of the poking and clamping sheath 2 is arc-shaped, and the part of the poking and clamping core 1 penetrating out of the bottom of the poking and clamping sheath 2 is provided with an inclined plane.

Stab card sheath 2 ground top shape and be the horn mouth shape, because of stabbing card sheath 2 and stabbing 1 size of card core less, conveniently dock and stab card sheath 2 and stab card core 1 and insert stabbing card core 1 in the card sheath 2.

Clinically, acute urine retention of patients suffering from prostatic hyperplasia or urethral injury, retention and catheterization failure, patients with advanced age combined with cardiopulmonary insufficiency undergo epidural anesthesia or general anesthesia to open and fistulize bladder 5, the anesthesia risk and the operation risk are increased, a puncture fistulization poking card (10mm poking card) for guiding bladder 5 is used, the middle of a core 1 of the bladder 5 fistulization poking card is designed to be a 2mm hollow pipeline 3, the tip and the tail end of the bladder 5 fistulization poking card are communicated with the hollow pipeline 3 poking the core 1, the diameter of the tip and the tail end of the tip are both 2mm, a small round hole at the tip can be designed to be a bevel circle, so that the sharpness of the poking core 1 is not reduced, a guide wire 4 with the diameter of 1mm can be placed in the hollow pipeline 3, the angle and the depth of the puncture of the bladder 5 poking card are guided by the guide wire 4 to smoothly enter the bladder 5, the hollow pipeline 3 of the puncture card can be seen to flow out due to the full pressure of the bladder 5 urine, further premature understanding puncture stabs the card and gets into bladder 5 smoothly to avoid blindly and then not control the degree of depth of puncture, avoided the intestines tube damage that the puncture too deeply leads to in the art, this operation is almost equal to the effect of placing bladder 5 fistulization under open direct-view, compares with open operation, and the operation risk and the wound of guide puncture fistulization are little, are operating time weak point. The operation process is that bladder 5 puncture fistulization can be done under two lateral finger local numbs above the pubic bone, successfully puncture bladder 5 with tiny pjncture needle, put into seal wire 4 to bladder 5 through the puncture needle again, extract the pjncture needle, get into the small round hole of seal wire 4 through bladder 5 fistulization puncture card, wear out from tail end small round hole, puncture and stab the card and have had the guide of seal wire 4, pull out and stab card core 1, keep seal wire 4 still in bladder 5, can get into bladder 5 through stabbing card sheath 2 with the silica gel drainage tube that seal wire 4 guide F18-F20 again, pull out and stab card sheath 2, keep somewhere the bladder 5 fistulization pipe of main entrance smoothly and make the fistula, it is fixed to sew up with the skin, treat bladder 5 fistulization formation regularly, the later stage can be to the patient of long-term, need to change the fistulization pipe, have polytype gasbag catheter of multiple type to select to change fistulization pipe when changing.

By utilizing the operation method, the operation method is almost equal to the effect of open bladder fistulization under direct vision when the fistulization tube with a large channel is placed, has the advantages of avoiding large anesthesia risk and open operation risk and wound, and has the advantages of short operation time, small damage, short hospitalization time, quick recovery after operation of patients, saving of hospitalization cost of the patients and better service for the patients.

All the technical features of the above embodiments can be arbitrarily combined (as long as there is no contradiction between the combinations of the technical features), and for brevity of description, all the possible combinations of the technical features in the above embodiments are not described; these examples, which are not explicitly described, should be considered to be within the scope of the present description.
