Abstract
An interbody tool may include an upper portion with an upper contact surface and a plurality of upper legs; a lower portion with a lower contact surface and a plurality of lower legs, each of the lower legs moveably connected to one of the upper legs; a plurality of gauges, each gauge configured to measure a position of one of the plurality of upper legs relative to a corresponding one of the plurality of lower legs; at least one actuator configured to selectively push the upper portion away from the lower portion; and at least one sensor for measuring a force exerted by the at least one actuator.
Claims20
An interbody tool, comprising:
- an upper portion comprising an upper contact surface and a plurality of upper legs;
- a lower portion comprising a lower contact surface and a plurality of lower legs, each of the lower legs moveably connected to one of the upper legs;
- a plurality of gauges, each gauge configured to measure a position of one of the plurality of upper legs relative to a corresponding one of the plurality of lower legs;
- at least one actuator configured to selectively push the upper portion away from the lower portion;
- and
- at least one sensor for measuring a force exerted by the at least one actuator.
A method of measuring an interbody space, comprising:
- inserting an interbody tool having an upper contact surface and a lower contact surface into an interbody space;
- activating at least one actuator of the interbody tool to expand a distance between the upper contact surface and the lower contact surface;
- monitoring, with a sensor, a characteristic of the at least one actuator;
- deactivating the at least one actuator when the characteristic reaches a predetermined threshold;
- and
- receiving information from a plurality of gauges positioned at a plurality of points between the upper contact surface and the lower contact surface about a distance between the upper contact surface and the lower contact surface at each of the plurality of points.
An interbody measurement system comprising:
- an interbody tool comprising:
- an upper portion comprising an upper contact surface;
- a lower portion comprising a lower contact surface;
- at least one actuator configured to selectively adjust a distance between the upper contact surface and the lower contact surface;
- and
- at least one sensor for measuring a characteristic of the at least one actuator;
- at least one processor;
- and
- at least one memory storing instructions for execution by the at least one processor that, when executed, cause the at least one processor to:
- receive data corresponding to the characteristic from the at least one sensor;
- and
- determine whether to de-activate the at least one actuator based on the data.
