Reciprocating Drive Optical Scanner for Surgical Endoprobes

An optical cannula assembly comprising

• an outer tube able to rotate about a longitudinal axis;
• an inner tube within the outer tube, able to rotate within the outer tube;
• a distal optical element attached to the outer tube;
• and
• a proximal optical element attached to the inner tube;
• wherein
• a proximal end of the cannula assembly is configured to engage a mechanical actuator to provide a reciprocating rotational motion to at least one of the outer tube and the inner tube for an arc period.

A method for using a microsurgical endoprobe having a cannula assembly, comprising:

• inserting the microsurgical endoprobe into a tissue, the microsurgical endoprobe having a cannula assembly with a proximal element and a distal element coupled to a mechanical actuator;
• rotating at least one of the proximal element and the distal element in a first direction for an arc period;
• performing a microsurgical procedure on the tissue;
• and
• rotating the at least one of the proximal element and the distal element in a second direction opposite to the first direction for the arc period.
