The World’s #1 suction rectal biopsy system for the diagnosis of Hirschsprung’s Disease is now available with a manometer.
Finally, the easy way to perform a suction rectal biopsy
Manufactured by Aus Systems, the rbi2 features a single-use sterile capsule tip that eliminates problems associated with current suction rectal biopsy equipment. The capsule houses an ultra-sharp blade for a clean cut, provides an airtight seal for precise suction, and captures the biopsy specimen for easy viewing. And the reusable hand piece is easy to care for.
With a reported accuracy rate of 99.7% and requiring no anesthesia, the suction rectal biopsy – considered the gold standard for the diagnosis of Hirschsprung’s Disease – is widely used without complications.
Now the rbi2 is the gold standard for performing the biopsy. Previous systems often made this otherwise simple bedside procedure cumbersome and more costly. Blades had to be regularly sharpened to prevent inconsistent or multiple biopsies, and unreliable sealing sometimes resulted in an inadequate specimen.
However, the rbi2 system eliminates these problems and helps ensure a quick, successful procedure. No more dull blades, accidental sharps injuries or inadequate specimens. You’ll always get:
- A clean, precise cut each and every time
- Consistent suction
- Uniform specimens
- Easy specimen access
Rbi2 Best Performance
To get the best performance from your rbi2 system, it’s important to understand the unique characteristics and essential techniques associated with using the device.
Understanding the critical combination of negative suction pressure and
gentle approximation of the capsules against the mucosa —
The single patient use manometer measures the amount of negative pressure and is used as a guide to let the operator know if the capsule is not placed against the mucosa.
A successful biopsy will be achieved when the capsule hole is covered by the mucosa, with the capsule itself gently approximated in the neutral position against the mucosa.
The blue diaphragm of the manometer will only react if the hole is covered – see Fig. 1 below.
The manometer will not indicate if too much pressure if being applied against the mucosa so it is critical not to push the capsule against the mucosa to avoid inadequate specimens.
Do not deliberately force the capsule against the mucosa—
Gently approximate the capsule tip in the neutral position to the mucosa – see Fig. 2 below.
Do not push or force the capsule against the mucosa. The mucosa will stretch and tighten, making it more difficult to withdraw the tissue into the capsule hole , or prevent tissue from entering the hole altogether – see Fig. 3 below.
Take your time –
There is no need to quickly fire the trigger the suction has been achieved. Because this system is airtight, there will be no loss of suction while taking the biopsy, so you can take your time!
Minimal suction required—
The unique design of the rbi2 capsule features an internal seal that fits tightly around the inner tube of the handpiece. This provides an airtight pathway from the front of the capsule all the way to the syringe. As a result, additional suction to account for suction loss, which is a technique needed with older systems, is not necessary.
Prior to firing the trigger, the mucosa is drawn into the hole in front of the blade.
When the trigger is fired the blade cuts the specimen and becomes lodged in the cutting block.
When the blade is fully advanced into the cutting block, the specimen is released into the capsule tip for retrieval.
After withdrawing the instrument from the patient, and prior to breaking the capsules open for specimen retrieval, check that the hole in the blade aligns with the hole in the capsule—you should see no silver blade.
If you can still see blade, simply fire the trigger to push the blade fully forward.
Failure to do this may make specimen removal difficult as it is possible the specimen will remain trapped between the blade and the cutting block.
