Abstract: A medical endodevice (1) for an intervention inside a body cavity (54) of a body of a human or animal being (5), comprising an elongated liaising structure (2; 29), an intervention tool (7), a positioning unit (3), a decoupling structure and at least two expandable members (62). The elongated liaising structure (2; 29) has a distal end (211; 2119) arrangeable in the body cavity (54) and a proximal end arrangeable outside the body while the distal end (211; 2119) is in the body cavity (54). The intervention tool (7) is arranged to manipulate a target tissue inside the human or animal body, wherein the intervention tool (7) is arranged at the distal end (211; 2119) of the liaising structure (2; 29). The positioning unit (3) has a moving formation (32) arranged to dislocate the intervention tool (7) relative to the target tissue. The decoupling structure is arranged to decouple the positioning unit (3) once it is arranged in the body cavity (54).

Abstract: A medical endodevice for an intervention inside a human or animal body includes an elongated liaising structure having a distal end arrangeable inside a body of the human or animal being and a proximal end arrangeable outside the body while the distal end is inside the body. The endodevice has an intervention tool arranged to manipulate a target tissue inside the human or animal body. The intervention tool is arranged at the distal end of the liaising structure. The endodevice further includes a positioning unit having a moving formation arranged to dislocate the intervention tool relative to the target tissue, and an anchoring formation arranged to fix the moving formation to a fixing tissue inside the human or animal body such that the target tissue is positioned in a workspace of the intervention tool.

Abstract: A medical endodevice (1) for an intervention inside a human or animal body comprises an elongated liaising structure (2) having a distal end arrangeable inside a body of the human or animal being and a proximal end arrangeable outside the body while the distal end is inside the body. The endodevice has an intervention tool arranged to manipulate a target tissue (51) inside the human or animal body. The intervention tool is arranged at the distal end (23) of the liaising structure (2). The endodevice (1) further comprises a positioning unit (3) having a moving formation (32) arranged to dislocate the intervention tool relative to the target tissue (51), and an anchoring formation arranged to fix the moving formation (32) to a fixing tissue (51) inside the human or animal body such that the target tissue (51) is positioned in a workspace of the intervention tool.
