UBE basics & Training Program

Unilateral Biportal Endoscopy

  • 1. Fluid medium surgery : continuous fluid flow · hydrostatic pressure
  • 2. Biportal surgery : Endoscope and instrument · move independently.
  • 3. Triangulation
  • 4. Semi-tubular system at working portal : no visual limitation · no motional limitation
  • 5. One hand surgery : no support with another hand
  • 6. Lens inside body : more close, deep and clear
  • 7. Lens to be movable(not fixed) : always, all-directional

1. Hydrostatic pressure

Optimal pressure in Op field : controlled by gravity (cm1.36 = mmHg)

2. Semi-tubular system at working portal

  • Visual limitation

    Motional limitation

  • Retractor part : rigid

    Free part : flexible

    Semi-tubular : rigid+flexible

3. UBE can perform just like microsurgery ? YES.

  • Topic : UBE (Unilateral Biportal Endoscopy)
  • Program Director : Dr. Son, Sankyu, M.D.

The training program consists of interactive discussions in the morning on surgery cases of the day,
observation of diverse UBE surgery cases and detailed explanation on fundamental principles of
surgical methodology of UBE by Dr. Son, SangKyu, M.D.

We hope this unique experience will give you the opportunity to learn the state-of-the art endoscopic
spine surgery technique in a practically effective ambience, with 100% personal attention.
