Abstract
A stabbing apparatus for penetration of a living body wall, having a stabbing apparatus body provided with a sharp edge, a pressure sensor disposed on the peripheral surface thereof to sense the pressure to which the sensor is subjected when stabbing a living body wall, and an indicator responsive to the sensed pressure above a predetermined level, whereby the depth of penetration of the stabbing apparatus body with respect to the living body wall is indicated.
Claims5
A stabbing apparatus for penetration of a living body comprising:
- a stabbing apparatus body having a sharp edge portion for penetrating the living body;
- sensor means disposed in said stabbing apparatus body for sensing a pressure to which said sensor means is subjected during penetration of a living body wall, and providing a pressure signal corresponding to said pressure;
- accumulator means coupled to said sensor means for accumulating information corresponding to the signal level of said pressure signal to provide an accumulated signal which corresponds to the depth of said penetration;
- and
- indicator means coupled to said accumulator means for indicating said penetration depth according to the magnitude of said accumulated signal.
