Abstract
A surgical instrument for releasable connection to a surgical tool having two or more sections that are able to articulate 360 degrees in differing increments and directions. The articulation of the sections allows for the distal end to be spatially offset from the proximal, yet maintain parallel longitudinal axes. The surgical instrument includes a force disc at the proximal end upon which a surgeon can exert a linear force which is transmitted to the distal end having a second tool such as a broach firmly attached thereto.
Claims13
An articulating surgical tool handle comprising:
- a force disc;
- a main section having a first end connected to the force disc;
- a center section;
- a connector body;
- a broach section configured for connection to a tool;
- a first cam mechanism connecting, and enabling relative rotation between, a second end of the main section and a first end of the center section around an axis of rotation that extends along longitudinal axes of the second end of the main section and the first end of the center section;
- a second cam mechanism connecting, and enabling relative rotation between, a second end of the center section and a first end of the connector body around an axis of rotation that extends along longitudinal axes of the second end of the center section and the first end of the connector body;
- and
- a third cam mechanism connecting, and enabling relative rotation between, a second end of the connector body and a first end of the broach section around an axis of rotation that extends along longitudinal axes of the second end of the connector body and the first end of the broach section,
- wherein at least one of the cam mechanisms enables 360 degrees of relative rotation.

- a second cam mechanism connecting, and enabling relative rotation between, a second end of the center section and a first end of the connector body around an axis of rotation that extends along longitudinal axes of the second end of the center section and the first end of the connector body;
- a third cam mechanism connecting, and enabling relative rotation between, a second end of the connector body and a first end of the broach section around an axis of rotation that extends along longitudinal axes of the second end of the connector body and the first end of the broach section,
- wherein at least one of the main section, center section, connector body or broach section has at least one bend in a longitudinal extent thereof.
