View Edit Delete	TOY-1	a housing that comprises the electronic circuit and the power supply;	206	Added by DJM 1 2022	1/19/22, 12:00 AM
View Edit Delete	TOY-1	In certain embodiments, the surgical device 200c may be configured to assist a surgeon in performing these one or more steps of the spinal surgery procedure. In one embodiment, the surgeon may align another instrument such as an awl, bone probe, surgical drill bit, of the like, with the surgical device 200c. In this manner, the instrument used has the target insertion trajectory. In another embodiment, the surgical device 200c and/or electronic circuit 300/400 may be coupled to another instrument such that tilting that instrument will indicate a current orientation angle.	146	Added by DJM 1 2022	1/19/22, 12:00 AM
View Edit Delete	TOY-1	FIG. 7C illustrates a bone probe 216 having a distal end that comes to a sharp point and proximal end that includes threads that connect the bone probe 216 to a shaft 210. The threads on one or the other of the bone probe 216 and the shaft 210 may be corresponding internal and external threads.	156	Added by DJM 1 2022	1/19/22, 12:00 AM
View Edit Delete	TOY-1	FIG. 7B illustrates a bone probe 216 having a distal end that includes a coaxial opening that extends from a distal end of the bone probe 216 to a proximal end. The coaxial opening may connect to an opening in, or be a same opening as, one in a shaft 210 such that the shaft 210 is cannulated. The coaxial opening may have a diameter that accepts passage of a variety of instruments that a surgeon may use as part of a procedure to deploy a fixation device (e.g., a pedicle screw). The coaxial opening may also facilitate the bone probe 216 remaining in contact with the cortical bone as an orientation angle is determined.	155	Added by DJM 1 2022	1/19/22, 12:00 AM
View Edit Delete	TOY-1	FIG. 7A illustrates a bone probe 216 having a distal end that comes to a sharp point and is connected to, and/or formed with, the shaft 210. The sharp point facilitates the bone probe 216 remaining in contact with the cortical bone as an orientation angle is determined.	154	Added by DJM 1 2022	1/19/22, 12:00 AM
View Edit Delete	TOY-1	Those of skill in the art will appreciate that as with the lights 480, the electronic circuit 300/400 may activate one or more speakers 470 with different sounds (e.g., beeps, blips, etc.) that indicate where a current orientation angle is relative to the desired or target orientation angle.	153	Added by DJM 1 2022	1/19/22, 12:00 AM
View Edit Delete	TOY-1	The light 480c may be configured to illuminate when the orientation angle of the surgical device 200c is substantially at a desired orientation angle. In one example, the light 480c may illuminate green when the orientation angle of the surgical device 200c is substantially at a desired orientation angle. In another embodiment, each of the lights 480 may illuminate the same color or flash or blink to indicate where a current orientation angle is relative to the desired or target orientation angle.	152	Added by DJM 1 2022	1/19/22, 12:00 AM
View Edit Delete	TOY-1	The light 480b may be configured to illuminate when the orientation angle of the surgical device 200c is inside a range of desired orientation angles. The range of desired orientation angles for the light 480b may be the same or different from the range of desired orientation angles for the light 480a. In one example, the light 480b may illuminate orange or yellow when the orientation angle of the surgical device 200c is inside a range of desired orientation angles.	151	Added by DJM 1 2022	1/19/22, 12:00 AM
View Edit Delete	TOY-1	In one embodiment, the light 480a may be configured to illuminate when the orientation angle of the surgical device 200c is outside a range of desired orientation angles. For example, the light 480a may illuminate red when the orientation angle of the surgical device 200c is outside a range of desired orientation angles. The range of angles may be measured in hundredths or tenths of degrees or degrees and may span a range of between 1 and 10 degrees.	150	Added by DJM 1 2022	1/19/22, 12:00 AM
View Edit Delete	TOY-1	In one embodiment, the surgical device 200c may use the lights 480a,b,c and/or speakers 470 to communicate when the orientation of the surgical device 200c is closer to, further away from or at the desired or target orientation angle. Those of skill in the art will appreciate a variety of ways, patterns, and/or configurations for how the electronic circuit 300/400 may activate the lights 480 and/or speakers 470 and/or haptic feedback devices 490 to convey how a current orientation angle relates to a desired or target orientation angle.	149	Added by DJM 1 2022	1/19/22, 12:00 AM
View Edit Delete	TOY-1	In the illustrated embodiment, the surgical device 200c may include one or more lights 480a,b,c and/or a speaker 470 as part of the user interface 254. The lights 480 may emit white or colored light of the same or different colors. The lights 480 may flash or blink. The speakers 470 may emit different sounds and/or tones of one or more frequencies and/or may do so at different frequencies.	148	Added by DJM 1 2022	1/19/22, 12:00 AM
View Edit Delete	TOY-1	Referring now to FIGS. 6A, 6B, in another embodiment, a user may input a desired or target orientation angle before or after placing the bone probe 216 on the cortical bone. The desired or target orientation angle may be input by activating the respective up arrow button 610 and/or down arrow button 612 until the display 262 shows the desired or target orientation angle. The electronic circuit 300/400 may store the desired or target orientation angle in memory media 560.	147	Added by DJM 1 2022	1/19/22, 12:00 AM
View Edit Delete	TOY-1	FIG. 7D illustrates a bone probe 216 having a distal end that comes to a sharp point and is connected to and/or formed with the shaft 210. The bone probe 216 may include a plurality of threads or flutes on the external surface of the bone probe 216. The threads or flutes can be configured to cut into bone such that rotation of the bone probe 216 can cause the bone probe 216 to drill down through the cortical surface and into the bone. In this manner, a surgeon may rotate the bone probe 216 either manually, or with a powered driver, to penetrate the cortical bone at a trajectory angle provided by the surgical device 200c.	157	Added by DJM 1 2022	1/19/22, 12:00 AM
View Edit Delete	TOY-1	The electronic circuit 300/400 may measure an orientation of the shaft in relation to the reference axis with the shaft in the desired orientation. The electronic circuit 300/400 may also determine an orientation angle of the shaft relative to the reference axis with the shaft in the desired location. The electronic circuit 300/400 may communicate the orientation angle to a user/surgeon. For example, the electronic circuit 300/400 may display the determined orientation angle using the display 262. The user/surgeon may confirm that the orientation angle satisfies a target insertion trajectory previously determined by a surgeon conducting the spinal surgery procedure. Then, a surgeon may proceed with one or more steps of the spinal surgery procedure.	145	Added by DJM 1 2022	1/19/22, 12:00 AM
View Edit Delete	TOY-1	At this stage, a surgeon may employ a variety of techniques to mark or preserve or denote the insertion trajectory. For example, the surgeon may strike the head of the surgical device 200c (with a hand, a hammer, and/or a mallet) to cause the bone probe 216 to penetrate the cortical surface of the vertebra 608. Or, the surgeon may press the surgical device 200c towards the vertebra 608 and cause the bone probe 216 to form a pilot hole in the pedicle. The pilot hole may then be used with other instruments (such as an electronic pedicle probe, or manual pedicle probe) to confirm the position of the pilot hole in the pedicle. The pilot hole may be tapped for a subsequent pedicle screw. In certain embodiments, a surgeon may press a pedicle probe through the pilot hole and into cancellous bone of the vertebra 608 to prepare the pedicle for a pedicle screw.	144	Added by DJM 1 2022	1/19/22, 12:00 AM
