When simulating puncture procedure, the equipment of puncture is consistent with equipment used in true operation, specific as follows:

F14 puncture needle, not Lai Shi urinary catheter punctures into liquid capsule and is placed in urinary catheter F14 two-chamber for combining；Sharp knife and Knife handle is cut for skin subcutaneous tissue；Urinary catheter tail end obturator can check water outlet status for closing urinary catheter tail end in advance； 5ml syringe, simulated skin local anaesthesia process and the water filling of urinary catheter liquid capsule are fixed；Needle holder, pincers, angular pin, silk thread are used for Suture urinary catheter is fixed.

The step of puncture, is close with true puncturing operation step, specific as follows: simulation puncture is placed in operation with model Platform is central, and tincture of iodine alcohol routine disinfection drape is laid on operating table.Liquid, mould are injected in simulated skin using 5ml syringe Quasi- skin surface local infiltration anesthesia, hand touch lid, using lid through hole center position as the position of suprapubic incision, due to lid Body is hard, through-hole radius 2.5-3cm, and the operation that suprapubic incision position is found in simulation around lid through-hole can be touched by hand. With sharp knife, notch to simulate cuts skin and subcutaneous tissue at simulated skin layer and simulation subcutaneous tissue at the heart in through-holes Operation, long incision 1cm.Conduit is inserted in puncture needle, but is not up to tip position, rotates puncture needle vertically downward along incision site It is punctured, namely pierces one wall of elastical cloth/band one and utricule, then inserting needle about 1cm after the sense that occurs falling through, check urine outflow Situation sets conduit along puncture needle, and tail end of conduit bifurcated is made to reach preset puncture needle end-position, and conduit liquid capsule fills the water 5ml.Even Needle tube drawing is pulled out upwards together with puncture needle, until being fixed on simulation bladder edge when having resistance for liquid capsule.Drainage of urine is examined again Situation.Simulated skin surface sutures two needle fixed catheters.Cutlery box is opened, examines bladder model after puncture whether complete, closed, goes Except conduit, checks point of puncture spray urine situation, check simulation punctio vesicae trace.

The 4th year medico is giveed training using this piercing method and this puncturing pattern, is divided into experimental group and control group, The puncture video recording for recording student, carries out statistical analysis after subjective and objective scoring.As a result: all classmates smoothly complete all operationss Step.Unprecedented obvious breakthrough sense is realized in puncture process.Statistic analysis result is shown: experimental group is equally divided into 90.28 ± 5.39, control group is equally divided into 85.81 ± 11.33.Independent samples t-test result t=3.123, p=0.003.Experimental group It is respectively 5% and 30% with the non-pass rate of control group.Experimental group is excellent, yield is respectively 55%, 40%, and control group is excellent, yield is respectively 20%, 50%；2 groups of data show that experimental group is better than control group.Puncture terminates, and cuts off simulation bladder gloves, utricule can be observed There is apparent puncturing hole, bladder is complete, after closed, removal conduit, and point of puncture has spray to urinate, in simulation wing on one rubberized tape one There are puncture marks on Guang.

Using the medical teaching of the utility model structure or the puncturing pattern of training, meet needed for suitable teaching mode The following requirement having: firstly, it simulates whole operation program close to true environment；Second, it, which is provided, accurately feels anti- Feedback, that is, the feel being commonly called as；Third can be used, it is ensured that all students can repeatedly practise behaviour with the multiple copies of quick copy Make；4th, model component is readily replaceable and cheap, and the combination of entire model is low in cost；Finally and most of all, Model can increase student to the understanding of operating process, the operation confidence of raising student.

In the utility model, using plastics by microwave furnace cutlery box as support device, fill water medical aseptic gloves simulate Bladder is packed for foamed plastics simulation abdominal wall structure, and orthopaedics simulates the skin and rectus aabdominis for being located at stomach wall with elastic force self-adhering fascia Protheca, therefore structure is simple, low cost, easily prepares, is rare practical teaching model.Pass through test of many times, it was demonstrated that this letter Single model can imitate the whole operation process of punctio vesicae fistulization, and operating handle is similar, and it is bright that sense is broken through when especially puncturing Aobvious and practical operation is closely similar, and cheap and simple can be replaced repeatedly rapidly, achievees the effect that model is recycled.

In all simulation puncture process, UROVISION punctio vesicae fistulization suit can be used, entirely puncture through Journey and the unique small difference of standard punctio vesicae fistulization program are that this set tubing is placed in puncture needle in advance, single step operation It completes to puncture and set pipe process, using conveniently, reliably, the wider application of suprapubic tract should be peomoted.This is practical The step of proposition, is identical in puncture suit and all operations step and Reuter that new structure model uses et al. article, When only last puncture is completed, puncture needle is not torn to pieces, puncture needle and its conduit Reusability.The tradition mark proposed compared with Goyal Quasi- method eliminates the process that puncture needle core places conduit again of pulling out, only with being placed in conduit in advance in puncture sheath needle.

It is imparted knowledge to students using this model, medico can be made to understand and learns all operationss process of punctio vesicae fistulization by heart, And breakthrough sense when penetrating bladder is realized in operation, and this feel is never realized in other training on operations. By the operation video recording for watching all students, hence it is evident that it can be seen that pause when break-through simulation bladder, at this moment puncture needle is again into 1cm Urine postposition pipe is flowed out in left and right, observation tube tail portion.By questionnaire survey, all students have smoothly completed above-mentioned steps, and declare Title has realized breakthrough sense, and 87.5% student declares in clinical practice from now on, needs to do the tight of bladder stoma if encountered Anxious situation, it is confident to carry out all operationss.

Although the model of the modelling of the utility model structure is fairly simple, only foamed plastics simulation stomach wall layer Secondary, the skin layer of orthopaedics self-adhering fascia simulation is pasted on medical rubber glove surface and reinforces simulation punctio vesicae face, prevents from puncturing When gloves explosion orthopaedics self-adhering fascia, but this modelling is simple, and cheaply, outer except puncturing suit, entire model is worth only It is about 2 dollars, very cheap compared to the model prices that Ashima Singal is worth 31.28 dollars, and production is convenient rapidly, only needs The simulation bladder and simulation stomach wall layer for replacing a gloving just use for next student, and replacing construction 5 minutes or so, Therefore, can with large supply student not by the time not by the training in place.
