Abstract
A surgical instrument is disclosed comprising a housing and a control circuit mounted to and/or embedded in the housing.
Claims20
1-30. (canceled)
A trocar for use during a surgical procedure, wherein said trocar comprises:
- a proximal end;
- a distal end;
- a shaft comprising a longitudinal aperture defined therethrough, wherein said longitudinal aperture is sized to receive a surgical instrument therethrough;
- a seal positioned within said longitudinal aperture, wherein said seal comprises a port to receive the surgical instrument therethrough;
- and
- a force sensor unit to detect a force applied to said shaft by the surgical instrument.
3 more elements
A trocar for use during a surgical procedure, wherein said trocar comprises:
- a proximal end;
- a distal end;
- a hollow shaft to receive a surgical instrument therethrough;
- a seal positioned within said hollow shaft, wherein said seal comprises a self-sealing port defined therein to facilitate a passage of the surgical instrument therethrough while preventing a proximal flow of a gas out of said trocar;
- and
- a force sensor circuit to detect a force applied to said hollow shaft by the surgical instrument therethrough.
3 more elements
A trocar for use during a surgical procedure, wherein said trocar comprises:
- a shaft, comprising:
- a proximal end comprising a proximal opening to receive a surgical instrument;
- a distal end comprising a distal opening;
- and
- a longitudinal aperture extending between said proximal opening and said distal opening;
- a seal positioned within said shaft, wherein said seal comprises a port to receive the surgical instrument therethrough while preventing a flow of a gas out of said trocar;
- and
- a force sensor circuit to detect a force applied to said shaft by the surgical instrument received therethrough.
5 more elements
The trocar of claim 17, further comprising:
- a haptic feedback generator;
- and
- a control system to communicate with said force sensor circuit and said haptic feedback generator, wherein said control system is to:
- receive a voltage potential detected by said force sensor circuit;
- compare said voltage potential to a predetermined threshold;
- actuate said haptic feedback generator based on said voltage potential exceeding said predetermined threshold.
