Distal communication array to tune frequency of RF systems
Disclosed is a surgical instrument, comprising a shaft, an articulation joint extending distally from the shaft, and an end effector extending distally from the articulation joint. The end effector comprises a jaw, and a staple cartridge seatable in the jaw. The staple cartridge comprises a cartridge body, staples removably stored in the cartridge body, and a first antenna. The surgical instrument further comprises a remote power source configured to supply power, a second antenna configured to cooperate with the first antenna when the staple cartridge is seated in the jaw to transmit at least one of the power and a data signal to the staple cartridge, and a tuning electronics package located in a cavity in a proximal portion of the end effector. The tuning electronics package is configured to facilitate a locally tunable wireless transmission of the at least one of the power and the data signal.
1. A surgical instrument, comprising:
a shaft;
an articulation joint extending distally from the shaft;
an end effector extending distally from the articulation joint, wherein the end effector is configured to grasp tissue, and wherein the end effector comprises:
a jaw; and
a staple cartridge seatable in the jaw, wherein the staple cartridge comprises:
a cartridge body;
staples removably stored in the cartridge body; and
a first antenna attached to the cartridge body; and
a remote power source configured to supply power;
a second antenna configured to cooperate with the first antenna when the staple cartridge is seated in the jaw to transmit at least one of the power and a data signal to the staple cartridge; and
a tuning electronics package located in a cavity in a proximal portion of the end effector, wherein the cavity is proximal to the second antenna and distal to the shaft, and wherein the tuning electronics package is configured to facilitate a locally tunable wireless transmission of the at least one of the power and the data signal, wherein the tuning electronics package comprises a processor and a memory storing program instructions, which when executed by the processor, cause the processor to implement an adjustment of a rate of the wireless transmission of the power.
2. The surgical instrument of claim 1 , wherein the program instructions further cause the processor to implement an adjustment of a rate of the wireless transmission of the data signal.
3. The surgical instrument of claim 2 , wherein the program instructions further cause the processor to implement an adjustment of a frequency associated with the wireless transmission of the at least one of the power and the data signal.
4. The surgical instrument of claim 3 , wherein the adjustment of the frequency is regionally specific.
5. The surgical instrument of claim 3 , wherein the program instructions further cause the processor to implement multiple sequential adjustments for the wireless transmission of the power then the data signal.
6. The surgical instrument of claim 5 , wherein the adjustments are made to minimize reflected signals.
7. A surgical instrument, comprising:
a shaft;
an articulation joint extending distally from the shaft;
an end effector extending distally from the articulation joint, wherein the end effector is configured to grasp tissue, and wherein the end effector comprises:
a jaw; and
a staple cartridge seatable in the jaw, wherein the staple cartridge comprises:
a cartridge body; and
staples removably stored in the cartridge body;
a remote power source configured to supply power;
an antenna array located distal to the shaft, the antenna array comprising:
a first antenna; and
a second antenna configured to cooperate with the first antenna when the staple cartridge is seated in the jaw to transmit at least one of the power and a data signal to the staple cartridge; and
an adaptive control system located in a cavity in a proximal portion of the end effector, wherein the cavity is proximal to the second antenna and distal to the shaft, and wherein the control system is configured to facilitate a locally tunable wireless transmission of the at least one of the power and the data signal through the antenna array, wherein the adaptive control system comprises a processor and a memory storing program instructions, which when executed by the processor, cause the processor to implement an adjustment of a rate of the wireless transmission of the power.
8. The surgical instrument of claim 7 , wherein the program instructions further cause the processor to implement an adjustment of a rate of the wireless transmission of the data signal.
9. The surgical instrument of claim 8 , wherein the program instructions further cause the processor to implement an adjustment of a frequency associated with the wireless transmission of the at least one of the power and the data signal.
10. The surgical instrument of claim 9 , wherein the program instructions further cause the processor to implement multiple sequential adjustments for the wireless transmission of the power then the data signal.
11. The surgical instrument of claim 10 , wherein the adjustments are made to minimize reflected signals.
