text: Yo, check it out, here's the deal,
  The authors got a plan, it's for real.
  They took a monopolar electrode, no joke,
  With a suction/irrigation channel, that's the stroke.
  
  They combined it all with a 0 degrees scope,
  4-mm Hopkins rigid telescope, giving hope.
  This three-in-one unit, multifunctional, you see,
  Inserted through a 7.5-mm outer sheath, so free.
  
  In a separate fix, the sheath was held tight,
  While a fourth instrument joined the fight.
  A balloon catheter or biopsy forceps, take your pick,
  Manipulated with the other hand, quick and slick.
  
  With a trephine, they made a 15-mm craniotomy,
  Opening the dura mater, that's how it should be.
  Tapped the ventricles with a brain needle, precise,
  Then inserted the scope for a clear visualize.
  
  Momentarily, they withdrew the telescope's might,
  Introduced the outer sheath, fixing it just right.
  With ease, the definitive procedure went down,
  Using the three-in-one instrument, no frown.
  
  In one hand, they had the multifunctional gear,
  In the other hand, the fourth instrument, clear.
  This neuroendoscopic system, it's a champ,
  Tested at the Vidyasagar Institute, no damp.
  
  Since May '98, they've been making waves,
  83 procedures, this system saves.
  Safe, versatile, and cost-effective, no doubt,
  Giving neurosurgeons freedom, that's what it's about.
