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.

[0077] 1 and 2 illustrate an endoscopic surgical instrument 10 comprising a handle 6 , a shaft 8 and an articulation end effector 12 pivotally connected to the shaft 8 at an articulation ...

Abstract

Discloses a surgical instrument capable of wireless communication between the control unit and the remote sensor, such as an endoscopic or laparoscopic instrument. Surgical instruments may include an end actuator having at least one sensor. The surgical instrument further comprises a conductive shaft, the distal end of which is connected to the end actuator, the sensor is electrically insulated from the shaft. The surgical instrument may further comprise a handle, which is connected to the proximal end of the axis. The handle comprises a control unit, the control unit is electrically connected to the shaft, so that the axis can act as an antenna to transmit a signal from the control unit to the sensor and receive the transmitted signal from the sensor. Other components electrically connected to the shaft can also send signals.
