Abstract
The self-biasing ankle clamp tibial alignment guide includes a clamp body, at least one lever arm outwardly extending from the clamp body, and an alignment rod generally upwardly extending toward a proximal end of a patient tibia and movable relative to the clamp body. A strap couples to the lever arm to exert a force thereon offset from a contact point where the clamp body pulls into engagement with a patient, thereby generating a moment about the contact point that causes the alignment rod carrying a cutting guide to bias forward into engagement with the patient.
Claims15
An ankle clamp tibial alignment guide, comprising:
- a clamp body having a patient-contacting interface selectively engageable with an ankle of a patient;
- a rod upwardly extending from the clamp body terminating in a cutting guide end distal from the patient-contacting interface;
- and
- a restraint selectively coupled to at least one lever arm, the at least one lever arm extending up from the clamp body and positioned entirely above the patient-contacting interface, wherein tightening the restraint generates a moment near where the patient-contacting interface selectively engages the ankle, to self-bias the cutting guide end of the rod generally toward the patient.
An ankle clamp alignment guide, comprising:
- a clamp body having a patient-contacting interface selectively engageable with an ankle of a patient;
- a rod upwardly extending from the clamp body terminating in a cutting guide end distal from the patient-contacting interface, the rod comprising an upper portion defining an upper alignment post and a lower portion defining a lever arm;
- and
- a restraint selectively coupled to the lever arm below the upper alignment post, the lever arm extending up from the clamp body and positioned entirely above the patient-contacting interface, wherein tightening the restraint generates a moment near where the patient-contacting interface selectively engages the ankle, to self-bias the cutting guide end of the rod generally toward the patient.
