Embodiment Construction

[0076] Various embodiments of the invention generally relate to surgical instruments having at least one remote sensor transponder and means for transmitting power and / or data signals from a control unit to the transponder(s). The present invention can be used with any type of surgical instrument that includes at least one sensor transponder, such as endoscopic or laparoscopic surgical instruments, but is particularly applicable where some features (such as a free swivel joint) prevent or facilitate the use of wires to connect to the sensor surgical instrument(s). Before describing the various aspects of the system, one surgical instrument in which the present invention may be used, an endoscopic stapling and cutting instrument (ie, an endocutter), will first be described by way of example.

Abstract

Disclosed is a surgical instrument with wireless communication between control unit and remote sensor, such as an endoscopic or laparoscopic instrument. The surgical instrument may comprise an end effector comprising at least one sensor. The surgical instrument may also comprise an electrically conductive shaft having a distal end connected to the end effector wherein the sensor is electrically insulated from the shaft. The surgical instrument may also comprise a handle connected to a proximate end of the shaft. The handle may comprise a control unit electrically coupled to the shaft such that the shaft radiates signals as an antenna from the control unit to the sensor and receives radiated signals from the sensor. Other components electrically coupled to the shaft may also radiate the signals.
