Surgical instrument with wireless communication between control unit and remote sensor
First Claim
1. A surgical instrument, comprising:
- a housing, comprising;
a power source configured to generate electrical power;
a control unit in electrical communication with the power source; and
a first element coupled with the control unit; and
a tool assembly, comprising;
a staple cartridge comprising a plurality of staples removably stored therein; and
a second element separate from the first element, wherein the control unit is configured to effect wireless transmission of the electrical power from the first element to the second element, wherein the wireless transmission of electrical power energizes the second element from a passive state to an energized state, wherein when in an energized state, the second element is configured to selectively communicate data received from a sensor to the control unit, wherein the tool assembly is remote from the housing, wherein the second element comprises a microchip, and wherein the microchip comprises a dynamic memory device and a non-dynamic memory device.

Abstract
A surgical instrument is disclosed including a housing and a tool assembly. The housing includes a power source configured to generate electrical power, a control unit in electrical communication with the power source, and a first element coupled with the control unit. The tool assembly includes a staple cartridge including a plurality of staples and a second element separate from the first element. The control unit is configured to effect wireless transmission of the electrical power from the first element to the second element. The wireless transmission of electrical power energizes the second element from a passive state to an energized state. When in an energized state, the second element is configured to selectively communicate data received from a sensor to the control unit. The tool assembly is remote from the housing. The second element includes a microchip that includes a dynamic memory device and a non-dynamic memory device.
