Integrated tool to insert pellet-releasing bioactive compound(s) in a region to be treated of a subject in need

A laparoscopic tool (10) comprising:

• a shaft (102) comprising a proximal end (1021) and a distal end (1022);
• a tip (100);
• a moving part (101) disposed between the distal end (1022) of the shaft (102) and the tip (100), the moving part (101) being attached to both the distal end (1022) and the tip (100), the moving part (101) being adapted to allow movement of the tip (100) relative to the shaft (102);
• wherein the tip (100) comprises a cylindrical part (1001) and a tapered part (1002) extending from the cylindrical part (1001) to an outlet (1003);
• the cylindrical part (1001) being attached to the moving part (101);
• the cylindrical part (1001) comprising a central channel (1004) surrounded by at least two peripheral channels (1005, 1006, 1007);
• the central channel (1004) and the peripheral channels (1005, 1006, 1007) extending across the cylindrical part (1001) of the tip (100) wherein the central channel (1004) comprises a pellet (20) together with a foldable retainer (21) in a folded position;
• the first peripheral channel (1006) comprising an opening (1008) at the tapered part (1002), the first peripheral channel (1006) comprising a first dissection tool (12, 13) that is capable to be protruded from the tip (100);
• a blinded peripheral channel (1005) comprising a location sensor (30) configured to be detected by an external localizer (31) for locating continuously the tip (100).
