A tool for removing and / or displacing a foreign body in a patient's body, comprising: a sleeve element (40) comprising a proximal end, a distal end and a central axis, wherein the sleeve element (40) comprises a tubular body defining an inner lumen (42) and is movable in the proximal and distal direction; an operative part (160) comprising a proximal end, a distal end and a central axis generally coaxial to the central axis of the sleeve element (40): a stabilizer which has a proximal end and a distal end; a plurality of intervention elements (166), each comprising a proximal end and a distal end; wherein the majority of engagement elements (166) are connected to the stabilizer and extend distally from the distal end of the stabilizer, wherein the engagement elements (166) are configured such that they transition between an open and a closed configuration in response to a force acting on the engagement elements (166), wherein the distal ends of the engagement elements (166) are configured such that they move away from the central axis of the operative part (160) when transitioning from the closed to the open configuration; and one or more grip elements (167) arranged on the stabilizers, extending from the engagement elements (166) to the central axis of the operative part (160) when the engagement elements (166) are in a closed configuration, wherein the sleeve element (40) comprises a plurality of secondary conduits (243), each of the secondary conduits (243) having a proximal and a distal end, and wherein the tool further comprises a pressure element (46) which includes a plurality of compression wires (146), wherein at least a part of each of the compression wires (146) is contained in the plurality of secondary lines (243), wherein each of the compression wires (146) has a proximal end and a distal end, wherein the compression wires (146) are configured such that they transition between an extended and a contracted configuration.

The application belongs to the technical field of medical devices, and is a kind of airway stent, comprising a stent body and a covering film arranged on the stent body, characterized in that the stent body comprises a fixed stent section and a movable stent section arranged at the end of the fixed stent section, and the covering film is arranged on the fixed stent section; at least one movable part in the form of an opening is arranged on the movable stent section, and the radial dimension of the movable stent section is greater than that of the fixed stent section. According to the airway stent in the application, the movable stent section with a radial dimension greater than that of the fixed stent section is arranged to increase the anchoring force of the airway stent, so that the airway stent is not prone to displacement, and the movable part in the form of an opening is arranged to increase the deformation space of the movable stent section, reduce the stimulation of the airway stent to the inner wall of the airway, and prevent the growth of granulation tissue.
