As evidence of the functional health of the product, we provide an electronic medium with visualization of a particular ultrasound or X-ray manipulation (if surgery requires it). It is important that the simulators are distinguished by endurance - withstand the maximum number of manipulations, be resistant to temperature differences or transportation features.
UROSTENT
The training device is intended both for practicing puncture skills under X-ray control, and for practicing the skills of manipulating endoscopic instruments in the kidney cavity using nephroscopes and pyeloscopes.
The training device is an imitation of a section of the lumbar part of the human body with the cavity system of the kidney and ureter. The material of the product is made of an elastomer with a hardness of about 10 points of Shore A system, which is as close as possible to the parameters of the patient’s tissues, while the cavity system of the kidney in the training device itself is absolutely identical to the cavity system of the human kidney.
Patent RU 180052 U1
- To start practicing the puncture skill, an nonslip mat (included in the kit) must be fixed on the operating table or other surface. To do this, wrap the operating table with elastic bands and lock blocking devices assembled on the band. If necessary, tighten the bands until the mat firmly get into place. The length of the bands is 95 cm. Place the training device on the mat.
- Foley’s urethral catheter (recommended diameter 16 Fr) is inserted into the end hole imitating the ureteral cut and inflated for fixation with a syringe with saline 20 ml.
- A C-bar is placed above the training device for fluoroscopic monitoring of the puncture.
- The renal cavity system is filled with contrast agent (1: 1), while the stereolithometric configuration of the renal cavity system filled with contrast agent (about 40-50 ml) will be displayed on the C-bar video monitor.
- Further, by manipulating the position of the C-bar, the skill of puncture by the “bull’s eye” method and triangulation is practiced.
Puncture by the “ bull’s eye” method *
- Set the position of the C-bar to the zero position and determine the calix of interest
- Move the C-bar to the +30 degree position so that only the shortest section of the calix is displayed.
- Place the needle so that you can see the calix as a circle and the cross section of the needle in the circle of the calix, so the calix will look like an eye, and the needle as a pupil – reasoned the name of the technique – “bull’s eye”
- Put forward the needle inward without changing the direction of the needle and control the depth by moving the C-bar to the zero position.
- When the needed calix is reached, take out the stylette of the needle and make sure that the position is correct – if the puncture is performed correctly, you should get an outflow of contrast agent.
Puncture by triangulation *
- Set the C-bar to zero and locate the calix of interest.
- Move about 5-7 cm away from the calix and perform a puncture.
- Control the direction of the needle in the zero position of the C-bar.
- Control the puncture depth with the C-bar brought to the lateral position from the needle.
- When the needed calix is reached, take out the stylette of the needle and make sure that the position is correct – if the puncture is performed correctly, you should get a contrast agent.
Bougienage and making a stroke for percutaneous surgery
- After performing the correct puncture of the renal cavity system (fluid is obtained), remove the stylette of the needle and insert the guidewire into the renal cavity.
- Along the guidewire, carry out the fascia bougie up to 10Cn in diameter under X-ray control.
- Remove the fascial bougie and install the final bougie, along which the cover planned to be placed under X-ray control.
- Install the cover over the bougie and remove the bougie
- Insert the nephroscope and ensure that the cover is placed properly.
Nephroscopy
