Abstract
A joint distraction lever comprising a lever body having a distal end and a proximal end opposite the distal end, the distal end having a handle portion and the proximal end having a working portion configured to be positioned between a first bone and a second bone of a joint. The joint distraction lever further comprising a strain gauge integrated into the lever body and positioned between the handle portion and the working portion, the stain gauge configured to measure a strain on the lever body indicative of a distraction force applied at the distal end during a distraction procedure.
Claims20
A joint distraction lever, comprising:
- a lever body having a distal end and a proximal end opposite the distal end, the distal end having a handle portion and the proximal end having a working portion configured to be positioned between a first bone and a second bone of a joint;
- and
- a strain gauge integrated into the lever body and positioned between the handle portion and the working portion, the strain gauge configured to measure a strain on the lever body indicative of a distraction force applied at the distal end during a distraction procedure.
A surgical system, comprising:
- a joint distraction lever, comprising:
- a lever body having a distal end and a proximal end opposite the distal end, the distal end having a handle portion and the proximal end having a working portion configured to be positioned between a first bone and a second bone of a joint;
- a strain gauge integrated into the lever body and positioned between the handle portion and the working portion, the strain gauge configured to measure a strain on the lever body indicative of a distraction force applied at the distal end during a distraction procedure;
- a computing system configured to provide a surgical plan;
- and
- a robotic device coupled with the joint distraction lever, the robotic device configured to apply a force to the handle portion in accordance with the surgical plan to cause the working portion to apply the distraction force.
A method of applying a distraction force during a distraction procedure, comprising:
- providing a joint distraction lever, comprising:
- a lever body having a distal end and a proximal end opposite the distal end, the distal end having a handle portion and the proximal end having a working portion configured to be positioned between a first bone and a second bone of a joint;
- a strain gauge integrated into the lever body and positioned between the handle portion and the working portion, the strain gauge configured to measure a strain on the lever body indicative of the distraction force applied at the distal end during the distraction procedure;
- inserting the joint distraction lever into a space between the first bone and the second bone;
- applying a force to the handle portion such that the working portion applies the distraction force to the joint;
- measuring, via the strain gauge, a force value associated with the distraction force;
- and
- outputting the measured force value associated with the distraction force.
