Description
Technical field
The utility model is related to the field of medical instrument technology, specifically a kind of fistulization catheter.
Background technology
Bladder stoma is because urethremphraxis or bladder are cut off, and bladder makees fistulization on pubis, makes urine drainage in vitro.
Currently, generally double ‘J' tube is used to carry out indwelling, still, the merging of double ‘J' tube is a link that is time-consuming and acquiring a certain degree of difficulty,
Surgery cost is high, and one end of double ‘J' tube is embedded to kidney, is easy to cause calculus, result in blockage, it is postoperative to also result in infection etc.
Symptom.
Utility model content
The purpose of this utility model is to provide a kind of fistulization catheter, which will not cause without being placed in kidney
The post-operative problems such as calculus, infection, and surgical procedure is simple, at low cost.
Technical solution adopted by the utility model to solve its technical problems is：
A kind of fistulization catheter, including urethral catheterization tube body, the urethral catheterization tube body includes leading portion catheter and back segment catheter, preceding
The head of section catheter is equipped with conduction hole, and the tail portion of back segment catheter is equipped with spiral helicine evacuating catheter；The leading portion catheter with
One group of domed rib is equipped between back segment catheter, rib is along the multiple circumferentially spaced setting of urethral catheterization tube body, each muscle
Item is collectively formed olive-shaped.
Further, the rib between the leading portion catheter and back segment catheter includes more than two, each group rib edge
Urethral catheterization tube body axially spaced-apart is arranged.
Further, the tube wall of the urethral catheterization tube body is marked equipped with insertion depth.
Further, every group of rib includes equally distributed 3 to 4.
Further, the leading portion catheter is the 1/5~1/3 of back segment catheter.
Further, the urethral catheterization tube body, rib and evacuating catheter are integrated.
The utility model has the beneficial effects that：Seal wire is penetrated into urethral catheterization tube body by urination nozzle, urethral catheterization tube body is sleeved on completely
After on seal wire, rib is straightened, so as to which catheter is successfully inserted into ureter from fistulization oral；Later, seal wire is extracted out,
Rib restores arch state, plays fixed function to catheter to be stuck in ureter, urine enters catheter by conduction hole
Body is finally excreted from evacuating catheter；It is not necessary that catheter is inserted into kidney, the post-operative problems such as calculus, infection, and hand will not be caused
Art is easy to operate, at low cost；Evacuating catheter in the shape of a spiral, can effectively prevent urine and backflow.
Description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples：
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the A-A cutaway enlargement diagrams of Fig. 1；
Fig. 3 is the status diagram that seal wire penetrates the utility model；
Fig. 4 be seal wire extraction after the utility model in intra-ureteral status diagram.
Specific implementation mode
In conjunction with shown in Fig. 1 and Fig. 2, the utility model provides a kind of fistulization catheter, including urethral catheterization tube body, urethral catheterization tube body packet
The head of the 1a of catheter containing leading portion and back segment catheter 1b, leading portion catheter 1a are equipped with conduction hole 2, the tail portion of back segment catheter 1b
Equipped with spiral helicine evacuating catheter 3；One group of domed rib 4, rib 4 are equipped between leading portion catheter 1a and back segment catheter 1b
Along the multiple circumferentially spaced setting of urethral catheterization tube body, each rib is collectively formed olive-shaped；Preferably, leading portion catheter 1a
Rib between back segment catheter 1b includes more than two, and the present embodiment selects two groups, and each group rib is axial along urethral catheterization tube body
Interval setting；Preferably, every group of rib includes equally distributed 3 to 4；The tube wall of urethral catheterization tube body is additionally provided with insertion depth label
5；The leading portion catheter 1a is the 1/5~1/3 of back segment catheter 1b.Medical plastic can be used in urethral catheterization tube body, rib and evacuating catheter
The common used materials integral structure such as material, resin, silica gel is made, and can as needed be arranged to different positions different hard
Degree, to meet the demands such as insertion, rebound reset.
In conjunction with shown in Fig. 3 and Fig. 4, in use, seal wire 6 is first penetrated urethral catheterization tube body, evacuating catheter 3 and urethral catheterization by evacuating catheter 3
After tube body is sleeved on completely on seal wire 6, evacuating catheter 3 is straightened with rib 4, so as to successfully by this catheter from fistulization
Mouth 7 is inserted into ureters 8；Stop being inserted into when reaching insertion depth label 5, later, extracts seal wire 6 out, rib 4 restores arch shape
State plays fixed function to be stuck in ureter 8 to catheter；Evacuating catheter 3 also restores spiral status, and urine is by conduction hole 2
