Controllable steerable fusing device

A steerable fusing device (50) comprising:

• a steerable instrument (100) having a proximal end (20) and a distal (40) end comprising a shaft (130), a bendable proximal part (120) configured to bend omnidirectionally in a curve and a bendable distal part (140) configured to bend omnidirectionally in a curve, the steerable instrument (100) configured such that the bendable distal part (140) bends responsive to bending of the bendable proximal part (120), and
• a fusing head (302) attached in fixed rotational relation to the bendable distal part (140) configured for fusing tissue captured between jaws (310, 320) of the fusing head (300),
• wherein the fusing head (300) is axially rotatable when the bendable distal part (140) is in a bent position by a complementary axial rotation of the bendable proximal part (120).
