Abstract:
1. An orthopedic impactor, comprising: a) an elongated body comprising a body sidewall extending along a longitudinal axis from a body proximal portion having a body proximal end spaced from a body distal portion having a body distal end, wherein the body proximal portion is configured to provide a handle for the impactor; b) a through-bore extending longitudinally through the elongate body from the body proximal portion to the body distal end; c) a connection rod disposed along the longitudinal axis in the through-bore, wherein the connection rod extends from a connection rod proximal end spaced from a connection rod distal end extending out beyond the body distal end; d) a linkage comprising a linkage proximal end spaced from a linkage distal end, wherein the linkage distal end is pivotally connected to the connection rod proximal end; e) a lever arm comprising a lever arm first portion having a lever arm first end spaced from a lever arm second portion, wherein the lever arm first end is pivotally connected to the linkage proximal end at a position along the body that is more proximal than the pivotal connection of the linkage distal end to the connection rod proximal end and wherein the lever arm first portion is pivotally connected to the body proximal portion at a location intermediate the lever arm second portion and the pivotable connection of the lever arm first end to the linkage proximal end; and f) wherein with the lever arm second portion in a first position spaced from both the connection rod and the longitudinal axis, a prosthetic cup is detachably connectable to the connection rod distal end, and g) wherein the lever arm second portion is manipulatable to pivot the lever arm first portion about the pivotable connection on the body proximal portion with the lever arm second portion moving from the first position to a second position spaced closer to both the connection rod and the longitudinal axis than when in the first position to thereby cause the pivotable connection of the lever arm first end to the linkage proximal end to move the linkage proximal end from a third position spaced from the longitudinal axis to a fourth position closer to the longitudinal axis than when in the third position, which movement causes the connection rod to move in a proximal direction within the through-bore in the elongated body with the connection rod distal end moving from a fifth position spaced outwardly from the body distal end to a sixth position spaced closer to the body distal end than when in the fifth position to thereby move the prosthetic cup connected to the connection rod distal end closer to the body distal end, and wherein in the second position, the lever arm first portion is proximal the lever arm second portion.
