SLS Series Light Surgical Microscope

Flexible arm: 

       1.  Arm assembly: The doctor can bring the arm to any position via the universal joints,. which ensures the microscope in the position suitable for the doctor.

       2. Torque adjusting handwheel: When the accessory is added to or removed from the microscope, adjust the handwheel to make the arm balanced at any position.

      3.  Arm blocking handwheel: The arm can be moved up and down by loosening the handwheel. After the arm is adjusted to the proper position, screw down the handwheel to keep the microscope stable.
