Claim:
1. A collapsible stylus for use in medical applications wherein a compressive force is applied at a treatment location, the stylus comprising: a light scattering tip at a distal end thereof; a strain gauge at a proximal end thereof; a shaft including an inner sleeve, an outer sleeve, and a light transmitting rod attached to the inner sleeve, the rod being partially housed within the inner sleeve and extending to the distal end of the stylus, the inner sleeve and the outer sleeve being releasably held to one another by a magnetic connection between at least one magnet on an inner surface of the outer sleeve and at least one magnet on the inner sleeve, the magnets being forced apart and the magnetic connection being broken in response to a predefined compressive force resulting in telescoping of the inner sleeve and the outer sleeve; a light source in communication with the rod; and a light controller in electric communication with the strain gauge and the light source, such that in use, a light signal, is emitted in a vicinity of the distal end, in response to a predefined force or a range of predefined forces.
