Abstract
A surgical instrument including a flex circuit comprising a sensor system.
Claims23
1-17. (canceled)
A surgical instrument, comprising:
- a housing;
- a shaft extending from said housing;
- an end effector extending from said shaft;
- a drive system;
- and
- a flexible circuit assembly extending within said shaft, wherein said flexible circuit assembly comprises a power transmission backbone and a signal communication backbone, and wherein said signal communication backbone is separated from said power transmission backbone.
3 more elements
A surgical instrument, comprising:
- a housing;
- a shaft extending from said housing;
- an end effector extending from said shaft;
- a drive system;
- and
- a flexible circuit assembly extending within said shaft, wherein said flexible circuit assembly comprises:
- a first region comprising a first sensor circuit, wherein said first sensor circuit is configured to generate a first ping signal in response to a first event;
- a second region comprising a second sensor circuit, wherein said first region and said second region are different, wherein said second sensor circuit is configured to generate a second ping signal in response to a second event;
- and
- a controller in communication with said first sensor circuit and said second sensor circuit, wherein said controller holds said first sensor circuit in a first low power mode until it receives said first ping signal, wherein said controller places said first sensor circuit in a first high power mode once it receives said first ping signal, wherein said controller holds said second sensor circuit in a second low power mode until it receives said second ping signal, and wherein said controller places said second sensor circuit in a second high power mode once it receives said second ping signal.
7 more elements
A surgical instrument, comprising:
- a housing;
- a shaft extending from said housing;
- an end effector extending from said shaft;
- a drive system;
- and
- a flexible circuit assembly extending within said shaft, wherein said flexible circuit assembly comprises:
- a first region comprising a first sensor circuit including a first sensor;
- a second region comprising a second sensor circuit including a second sensor, wherein said first region and said second region are different;
- and
- a controller in communication with said first sensor circuit and said second sensor circuit, wherein said first sensor circuit is in a first low data bandwidth mode until it receives a first ping signal from said controller, wherein said first sensor circuit enters into a first high data bandwidth mode when it receives said first ping signal, wherein said second sensor circuit is in a second low data bandwidth mode until it receives a second ping signal from said controller, and wherein said second sensor circuit enters into a second high data bandwidth mode when it receives said second ping signal.
7 more elements
A surgical instrument drive system, comprising:
- an electric motor;
- a rotary drive shaft driveable by said electric motor;
- a drive member driveable by said rotary drive shaft;
- an array of magnetic elements mounted to said rotary drive shaft;
- an array of sensing coils configured to detect the presence of said array of magnetic elements;
- and
- a controller in communication with said array of sensing coils, wherein said controller is configured to assess the position of said drive member by data from said array of sensing coils.
