Torque sensor with decision support and related systems and methods
A surgical system includes a power tool that generates torque; a torque sensor for measuring a torque characteristic of the power tool; a user interface; at least one processor; and a memory. The memory stores instructions for execution by the at least one processor that, when executed, cause the at least one processor to: receive torque data from the torque sensor, the torque data corresponding to the measured torque characteristic; evaluate the torque data; and execute a predetermined action based on the evaluation.
1 . A device, comprising:
a torque sensor for measuring a torque characteristic during a drilling, tapping, or screw insertion surgical procedure;
a processor; and
a memory storing instructions for execution by the processor that, when executed, cause the processor to:
receive data from the torque sensor corresponding to the measured torque characteristic;
cause the drilling, tapping, or screw insertion surgical procedure to stop when the measured torque characteristic satisfies a predetermined criterion;
automatically generate a recommendation based on at least one of the measured torque characteristic and the predetermined criterion, wherein the recommendation comprises a description of a proposed adjustment to a surgical plan;
cause the recommendation to be displayed via a user interface;
receive a user input in response to the recommendation; and
resume the drilling, tapping, or screw insertion surgical procedure based on the user input.
2 . The device of claim 1 , wherein the recommendation corresponds to changing one of a tap size, a drilling diameter, or a screw size.
3 . The device of claim 1 , wherein the recommendation corresponds to adding or removing a screw from a preoperative plan.
4 . The device of claim 1 , wherein the predetermined criterion is based on historical data corresponding to measured torque characteristics and patient outcomes.
5 . The device of claim 1 , wherein the recommendation comprises a change in a number of screws used in the surgical plan.
6 . The device of claim 5 , wherein the number of screws used in the surgical plan is decreased according to the recommendation.
7 . The device of claim 5 , wherein the recommendation indicates a change to the surgical plan to utilize a different screw.
8 . The device of claim 5 , wherein the recommendation indicates an instruction to re-drill a previously drilled hole.
9 . The device of claim 5 , wherein the recommendation indicates an instruction to re-tap a previously tapped hole.
10 . The device of claim 1 , wherein the torque characteristic comprises a peak torque, and the instructions enable the processor to evaluate the peak torque relative to a predetermined threshold.
11 . The device of claim 10 , wherein when the peak torque exceeds the predetermined threshold, the recommendation comprises stopping a power tool.
12 . The device of claim 1 , wherein the torque characteristic comprises an accumulated torque, and the instructions enable the processor to compare the accumulated torque with a predetermined threshold.
13 . The device of claim 1 , wherein the data comprises first torque data and second torque data indicating whether or not a first screw and a second screw were seated according to the surgical plan.
14 . A system, comprising:
a processor; and
a memory storing instructions for execution by the processor that, when executed, enable the processor to:
receive, from a torque sensor, data corresponding to a measured torque characteristic during a drilling, tapping, or screw insertion surgical procedure;
pause, when the measured torque characteristic satisfied a predetermined criterion, the drilling, tapping, or screw insertion surgical procedure;
automatically generate a recommendation based on at least one of the measured torque characteristic and the predetermined criterion, wherein the recommendation comprises a description of an adjustment to a surgical plan; and
cause the recommendation to be displayed to a user interface.
15 . The system of claim 14 , wherein the recommendation corresponds to changing one of a tap size, a drilling diameter, or a screw size.
16 . The system of claim 14 , wherein the memory stores additional instructions for execution by the processor that, when executed, further enable the processor to:
receive a user input in response to the recommendation; and
cause the drilling, tapping, or screw insertion surgical procedure to resume based on the user input.
17 . The system of claim 14 , wherein the recommendation comprises a change in a number of screws used in the surgical plan.
18 . The system of claim 14 , wherein the measured torque characteristic comprises a peak torque, and the instructions enable the processor to evaluate the peak torque relative to a predetermined threshold.
19 . The system of claim 14 , wherein the data comprises first torque data and second torque data indicating whether or not a first screw and a second screw were seated according to the surgical plan.
20 . The system of claim 14 , wherein the measured torque characteristic comprises an accumulated torque, and the instructions enable the processor to compare the accumulated torque with a predetermined threshold.
