Abstract
The present invention relates to a spring arm and a laser treatment apparatus including same and, particularly, to a spring arm for a laser treatment apparatus, which can provide an appropriate support force according to a change in the center of gravity of a link at an initial high rotation angle and at a low rotation angle during use, and a laser treatment apparatus including same. According to the present invention, a user fatigue degree can be reduced and accuracy of the apparatus when in use can be improved.
Claims13
A spring arm for a laser treatment apparatus, which comprises:
- a mast comprising a first end that is mounted to a main body;
- a connecting part;
- an arm connected to a second end of the mast and configured to pivot in a vertical direction around the connecting part connected to the mast, wherein a laser path is provided inside the arm;
- a support link comprising an arm supporting part configured to pivot around the connecting part and configured to support the arm on a first side of the connecting part;
- an elastic part supporting part disposed on a second side of the connecting part that is opposite to the first side;
- and
- an elastic part having a first end connected to the elastic part supporting part, and a second end connected to the mast,
- wherein the elastic part comprises a first hinge part and a second hinge part,
- the first hinge part is connected to the elastic part supporting part, and
- the second hinge part is connected to the mast and configured to pivot about a first axis perpendicular to and offset from a central axis of the mast, so as to allow the elastic part to transmit a different support force to the arm depending on a vertical rotation angle of the arm.
