An intravascular interventional tactile probe having a touching force range and position information feedback, comprising: a central column (7); a plurality of side wall electrodes (2) arranged on the periphery of the central column (7); a touch sleeve (1) which has electrical conductivity and can move relative to the central column (7) in an axial direction and in a radial direction; a top touch electrode (3) which can be movably connected to the central column (7); and an early-warning electrode (4) which can generate a side touch position signal when the touch sleeve (1) moves relative to the central column (7) in the radial direction and is electrically connected to at least one of the plurality of side wall electrodes (2). When moving for a first distance (d1) relative to the central column (7) in the axial direction, the touch sleeve (1) can be electrically connected to the top touch electrode (3) so as to generate a top touch signal, and when the axial displacement of the touch sleeve (1) relative to the central column (7) reaches the second distance (d2), the touch sleeve (1) can be electrically connected to the early-warning electrode (4) and generate an early-warning signal. The tactile probe having the above structure can distinguish a touch position and can indicate the magnitude of a touching force as well. |
