Abstract:
A surgical device (1) comprising:an elongate, flexible and tubular arm (3) which has a distal end and a proximal end;a flexible pulling means (6) which is movably arranged inside the arm (3) essentially over the entire length thereof;a tool (4) which is arranged at the distal end of the arm (3) and which comprises at least two parts (11, 12), which are arranged movable in relation to each other by operation of said pulling means (6); andan operating means (15) which is arranged at the proximal end of the arm to operate said pulling means (6) and, thus, said tool (4), characterised in that said arm (3) is made of a material which resumes its shape by heating, preferably a memory metal, which has a transformation temperature which allows the arm (3) to be deformable to the desired shape at room temperature and to keep the thus obtained shape at a patient's body temperature during use of the device (1), so as then to allow resumption of its original shape when exposed to a temperature exceeding the body temperature.
