Abstract

A surgical instrument including an end effector having at least one sensor. The instrument includes a distal stapling unit for performing at least one surgical task operatively connected to a remotely controllable user interface. The instrument further includes an electrically conductive shaft having a distal end connected to the end effector, wherein the sensor is electrically insulated from the shaft. The instrument also includes a housing at a proximate end of the shaft configured to receive mechanical or electrical inputs. In addition, the instrument has a receiver unit electrically insulated from the shaft configured to receive and send wireless signals from and to the sensor.

Claims

1. A surgical instrument comprising:

an end effector comprising at least one sensor;

a distal stapling unit for performing at least one surgical task operatively connected to a remotely controllable user interface

an electrically conductive shaft having a distal end connected to the end effector wherein the sensor is electrically insulated from the shaft; and

a housing at a proximate end of the shaft, configured to receive at least one of mechanical or electrical inputs; and

a receiver unit electrically insulated from the shaft configured to receive and send wireless signals from and to the sensor.

2. The surgical instrument of claim 1, wherein the at least one sensor comprises a magnetoresistive sensor.

4. The surgical instrument of claim 1, wherein the at least one sensor comprises a pressure sensor.

5. The surgical instrument of claim 1, wherein the at least one sensor comprises a RFID sensor.

6. The surgical instrument of claim 1, wherein the at least one sensor comprises a MEMS sensor.

7. The surgical instrument of claim 1, wherein the at least one sensor comprises an electromechanical sensor.
