The protective hull (120) acts as a shield to protect tissue that may lie under the instrument tip (104) from damage during treatment. The instrument (100) may be particularly useful in procedures performed in gastrointestinal tract, where a bowel perforation is a concern, or in the pancreas, where damage to the portal vein or the pancreatic duct may occur when a tumour or other abnormality being resected, dissected is or removed.
