Paragraph Number

8

One general aspect of the present disclosure can include a surgical device for intraoperative angle measurements during surgery on a patient that includes a shaft that may include: a proximal end; and a distal end opposite the proximal end, the distal end may be configured to contact cortical bone of a patient. The device includes an electronic circuit coupled to the shaft, the electronic circuit may be configured to measure an orientation angle, the electronic circuit may include: a zero-out switch configured to convey a zero-out signal; a calibration circuit configured to determine a reference axis for the electronic circuit in response to the zero-out signal; a measurement circuit configured to measure an orientation of the shaft in relation to the reference axis as a user tilts the shaft to a desired orientation, the measurement circuit may include an orientation sensor; a control circuit coupled to the switch, calibration circuit, and measurement circuit and configured to determine an orientation angle of the shaft relative to the reference axis; a display device coupled to the control circuit and configured to display the orientation angle to a user. The device includes a power supply configured to provide electric current to the electronic circuit.
