39. Surgical instrument (51) adapted to cardiac surgery, and in particular to atrial defibrillation comprising insertion means for insertion inside the heart chamber (100), and cutting means (50) connected at a connection zone (540) to said insertion means, for creating lesions inside the heart chamber (100), said instrument (51) being such that both its translation and rotation movements are controlled by a robotic system (300) preferably coupled to a 3D-imaging system (400),
wherein the insertion means correspond to a rigid elongated stem (52) delimited by an outer wall (521), with a main axis (A), and having a proximal end (523) and a distal end (522), said proximal end (523) being connected to the robotic system (300), while the distal end (522) is free; and wherein the cutting means comprise a flexible spreadable support structure (510) with an inner surface (511) and an outer surface (512), and an electrode mesh or network (500,500′
,500″
, . . . ) arranged on the outer surface (512) of said support structure (510).- View Dependent Claims (40, 41, 42)
- 46. Surgical instrument (81) adapted for hepatic surgery and comprising insertion means for insertion inside a target organ, and heating means for coagulating specific tissue regions inside said target organ, said heating means being connected to said insertion means, said instrument (81) being capable of translation and rotation movements controlled by a robotic system preferably coupled to a 3D-imaging system and being adapted for intra-hepatic surgery.
