TOY-1 |
A surgical device for intraoperative angle measurements during surgery. The surgical device includes a shaft having a bone probe configured to remain in contact with cortical bone of the patient while a user orients the shaft to a desired orientation. The device includes a housing having an electronic circuit configured to measure an orientation angle. The electronic circuit may include: an input device configured to receive user input data; a measurement circuit configured to measure a change in orientation of the shaft in relation to a reference axis; a control circuit coupled to the input device and measurement circuit and configured to determine the orientation angle of the shaft relative to the reference axis; and an output device configured to communicate the orientation angle to the user. The device includes a power supply configured to provide power to the electronic circuit. |
