Abstract
A surgical system includes a disposable force sensor pod that includes a load cell and a mounting feature. The surgical system also includes a computing system configured to be placed in electronic communication with the disposable force sensor pod and receive a force measurement from the disposable force sensor pod. The disposable force sensor pod is configured to be removeably coupled to a distraction device using the mounting feature.
Claims20
A joint distraction device, comprising:
- a first member;
- a hinge coupled to the first member;
- a second member comprising a distal portion and a proximal portion, the second member coupled to the hinge at a position between the distal portion and the proximal portion;
- a third member coupled to the hinge and manipulable to exert a force on the proximal portion of the second member that causes the distal portion to rotate away from the first member;
- and
- a disposable force sensor pod configured to be removeably coupled to at least one of the second member or the third member;
- wherein the second member comprises a mount configured to removably couple the disposable force sensor pod to the proximal portion;
- and
- the third member comprises a protrusion configured to exert the force on the second member via the force sensor pod when the disposable force sensor pod is coupled to the mount.
