Wireless communication in a robotic surgical system
In one embodiment, an insertion axis of a robotic manipulator is provided, the insertion axis including a base link operably coupled to a distal end of a manipulator arm, and a carriage link movably coupled to the base link along a lengthwise axis, the carriage link including a remote printed circuit assembly and transceiver for wirelessly communicating with a main printed circuit assembly external to the insertion axis. A robotic surgical system including such an insertion axis and a method for wireless communication in the system are also provided.
1. A link assembly of a robotic manipulator, comprising:
a base link operably coupled to a distal end of a manipulator arm, wherein the base link includes a clamp adapted to mount a cannula; and
a carriage link slidably coupled to the base link along a lengthwise axis of the link assembly,
wherein the carriage link includes an instrument interface adapted to mount an instrument having an instrument shaft,
wherein the base and carriage links have an extended configuration in which a portion of the carriage link extends beyond the base link along the lengthwise axis and the carriage link is configured for telescoping motion relative to the base link to move a distal end of the instrument shaft relative to the clamp.
2. The link assembly of claim 1 , wherein the instrument interface is adapted to mount an instrument having an end effector selected from the group consisting of jaws, scissors, graspers, needle holders, micro-dissectors, staple appliers, tackers, suction irrigation tools, clip appliers, cutting blades, cautery probes, irrigators, catheters, and suction orifices.
3. The link assembly of claim 1 , wherein the carriage link includes an indicator and a manipulator clutch button.
4. The link assembly of claim 3 , wherein the indicator provides a visually identifiable signal in response to a received control signal.
5. The link assembly of claim 1 further comprising a transmission system for moving the carriage link relative to the base link.
6. A link assembly of a robotic manipulator, comprising:
a base link operably coupled to a distal end of a manipulator arm, wherein the base link includes a clamp adapted to mount a cannula; and
a carriage link slidably coupled to the base link along a lengthwise axis of the link assembly,
wherein the carriage link includes an instrument interface adapted to mount an instrument having an instrument shaft,
wherein the base and carriage links have an extended configuration in which a portion of the carriage link extends beyond the base link along the lengthwise axis and the carriage link is configured for telescoping motion relative to the base link to move a distal end of the instrument shaft relative to the clamp, and
wherein the carriage link includes a circuit assembly, a power source for the circuit assembly, and a transceiver for wirelessly communicating with a main circuit assembly external to the link assembly.
7. The link assembly of claim 6 , wherein the circuit assembly and transceiver are configured to transmit data selected from the group consisting of a system state, a sterile adaptor state, and an instrument state.
8. The link assembly of claim 6 , wherein the circuit assembly and transceiver are configured to transmit data selected from the group consisting of instrument identification, LED control, clutch button state, and Hall-effect sensor state.
9. The link assembly of claim 6 , wherein the carriage link includes an LED indicator and a manipulator clutch button.
10. The link assembly of claim 6 , wherein the instrument interface is adapted to mount an instrument having an end effector selected from the group consisting of jaws, scissors, graspers, needle holders, micro-dissectors, staple appliers, tackers, suction irrigation tools, clip appliers, cutting blades, cautery probes, irrigators, catheters, and suction orifices.
11. The link assembly of claim 6 , wherein the power source includes a battery selected from the group consisting of a rechargeable battery and a disposable battery.
