ELECTROMECHANICAL SURGICAL DEVICE WITH SIGNAL RELAY ARRANGEMENT

摘要

A surgical instrument (4010) configured to relay a low-power signal from an end effector (4002) to a remote device (4014) is disclosed. The surgical instrument may comprise a handle, a shaft extending distally from the handle, and an end effector attached to the distal end of the shaft. A sensor (4116) may be disposed in the end effector. The sensor may generate a signal (4006) indicative of a condition at the end effector. A transmitter (4124) may be located in the end effector. The transmitter may transmit the signal from the sensor at a first power level. The signal may be received by a relay station (4008) located proximally to the shaft. The relay station is configured to retransmit the signal (4012) at a second power level, wherein the second power level is higher than the first power level.
