Autoclavable endoscope for endoscopic imaging systems

An endoscope comprising:

• a connection portion for connecting the endoscope to a camera head;
• a needle assembly;
• a sleeve that is fixed relative to the needle assembly;
• a focusing optic assembly housed within the sleeve and comprising at least one optical component, the focusing optic assembly being translatable relative to the sleeve for adjusting a focus of the endoscope;
• a user-engageable focus ring configured to translate the focusing optic assembly relative to the sleeve;
• a user-engageable rotator operably coupled to the needle assembly and the sleeve and rotatable independently of the user-engageable focus ring to rotate the needle assembly and sleeve relative to the user-engageable focus ring and the connection portion to adjust a view direction of the needle assembly without adjusting the focus of the endoscope;
• wherein the focusing optic assembly is magnetically coupled to a magnetic coupling assembly located externally to the sleeve such that translation of the magnetic coupling assembly translates the focusing optic assembly;
• wherein the user-engageable focus ring is configured to engage the magnetic coupling assembly such that rotation of the user-engageable focus ring causes translation of the magnetic coupling assembly;
• and
• wherein the user-engageable focus ring and the magnetic coupling assembly engage via one or more pins fixed to one of the user-engageable focus ring or the magnetic coupling assembly and one or more slots in the other of the user-engageable focus ring or the magnetic coupling assembly.
