Description

Bladder puncture outfit

Technical Field

The utility model relates to the field of medical equipment, specifically a bladder puncture outfit.

Background

In medical clinical treatment, bladder puncture operation is frequently required to relieve acute and chronic obstruction of the lower urinary tract or ensure the healing after the lower urinary tract operation. The operation steps are as follows: 1. the patient holds urine to make the bladder in full state; 2. the patient lies in supine position, kowtows the upper part of the pubic symphysis (lower abdomen), and determines the filling state (if necessary, ultrasonic B is determined); 3. the puncture point is 2-3 cm above the bone, and sterilized and laid with sterile towel; 4. under the local anesthesia of procaine, a 0.5 cm incision is longitudinally cut, and a knife tip cuts open the rectus abdominis anterior sheath; 5. the bladder puncture fistulization needle directly penetrates into the bladder from the cut, the inner core is pulled out, and when urine flows out, a catheter is placed, and the inner bladder is fixed; 6. and (5) sewing and fixing the skin. In the operation process, after the needle core of the bladder puncture needle is pulled out, only the sleeve (tube) is kept in the original position so as to be convenient for placing the catheter in the next step, and at the moment, due to the pulling-out of the needle core, the sleeve formed by the two pieces can form dislocation under the action of the contraction of the muscular tissues of the abdominal wall of a patient or when an operator operates carelessly. Such misalignment presents the following risks: 1. the catheter has failed to penetrate into the bladder from the cannula (two-piece formed cavity); 2. the two staggered sleeves can not be restored to the original positions under the contraction of abdominal muscle of a patient; 3. the sleeve is only pulled out, but the original hole from the abdominal wall to the bladder wall of the patient formed by puncture cannot be used any more, so that the body tissue of the patient is damaged, and urine leakage can be formed.

In addition, the existing puncture needle has no depth mark in the using process, so that the depth of the puncture needle is inconvenient to observe, and whether the needle point reaches or enters the bladder is difficult to estimate; when the existing puncture needle is used, after the existing puncture needle enters a bladder, the whole needle core needs to be pulled out, and a large amount of urine is gushed out to judge that the bladder puncture fistulization needle enters the bladder, so that the use is inconvenient.

Disclosure of Invention

Aiming at the technical defects, the utility model aims at providing a bladder puncture outfit, the outer wall of the sleeve of which is provided with scales to facilitate the control of the puncture depth, and the splicing position of two semicircular sleeves of the sleeve can be fixed, so that the dislocation is not easy to occur; after the pore passage in the needle core penetrates into the bladder, the bladder puncture needle can be judged to enter the bladder by outflow of trickle urine, so that the use is more convenient.

In order to solve the technical problem, the utility model adopts the following technical scheme:

the bladder puncture outfit is characterized by comprising a sleeve and a puncture needle core, wherein the sleeve consists of two semicircular sleeves, one end of each semicircular sleeve is symmetrically provided with two connecting lugs, and the connecting lugs at one end of each semicircular sleeve correspond to one another; the connecting lugs are provided with through holes, and the two corresponding connecting lugs are fixedly connected through bolts and nuts; the outer side wall of the sleeve is provided with scale marks;

the puncture needle core is arranged in the sleeve, a pore channel is arranged in the puncture needle core, and a plug core is plugged at one end of the pore channel.

The utility model has the advantages that 1, the outer wall of the sleeve is provided with scales to facilitate the control of the puncture depth, which is convenient for judging whether the needle point reaches or enters the bladder, and meanwhile, when the catheter is fed, the feeding depth is relatively estimated; 2. holes are punched on the connecting lugs of the sleeves, and the two semicircular sleeves are fixed by bolts and nuts to be difficult to form dislocation; 3. a fine pore passage is reserved in the needle core, after the needle core penetrates into the bladder, the bladder fistulization needle can be judged to enter the bladder by flowing out of the fine pore passage through fine urine, and the use is more convenient.

Description of the reference numerals:

the puncture needle comprises a semicircular sleeve 1, a connecting lug 2, a through hole 3, a scale mark 4, a puncture needle core 5, a fine hole channel 6, a blocking core 7, a nut 8 and a bolt 9.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1-3, the bladder puncture outfit comprises a cannula and a puncture needle core 5, wherein the cannula comprises two semicircular cannulas 1, two connecting lugs 2 are symmetrically arranged at one end of each semicircular cannula 1, and the connecting lugs 2 at one end of each semicircular cannula 1 are in one-to-one correspondence; the connecting lugs 2 are provided with through holes 3, and the two corresponding connecting lugs 2 are fixedly connected through bolts 9 and nuts 8; the outer side wall of the sleeve is provided with scale marks 4;

the puncture needle core 5 is arranged in the sleeve, a pore channel 6 is arranged in the puncture needle core 5, and a plug core 7 is plugged at one end of the pore channel 6.

The puncture depth is controlled by the scale marks 4 in the bladder puncture process, after the puncture is successful, the puncture needle core 5 is pulled out, after the catheter is placed in the casing, the casing is pulled out, and then the bolt 9 is loosened to take down.

The two semicircular sleeves forming the sleeve are fixed through bolts 9 and nuts 8 and are not easy to misplace.

The outer wall of the designed sleeve of the utility model is provided with the scales to facilitate the control of the puncture depth, to judge whether the needle point reaches or enters the bladder, and to estimate the feeding depth when the catheter is fed; holes are punched on the connecting lugs 2 of the sleeves, and the two semicircular sleeves 1 are fixed by bolts 9 and nuts to be difficult to form dislocation; a fine pore passage 6 is left in the needle core, after penetrating into the bladder, the urine with fine flow flows out from the fine pore passage 6, so that the cystostomy needle can be judged to enter the bladder, and the use is more convenient.
