An adjustable electrode surface RF-pencil
Problem: Electrode tip of RF-pencil is too large causing inaccuracy.
NEED Statement: Develop a RF-pencil which has a mechanism allowing surgeon to limit the electrode surface during the surgery without the help of the nurses and additional polymer material.
- The wheel can be turned upwards to move the movable part upwards and limit the electrode surface or downwards for prolonging the electrode length by moving the movable part downwards.
- A small mechanical display will show the adjusted electrode length in millimetre.
- Change limitation of electrode surface during coagulation process (interactive)
- No need for manual adjustment
