Abstract
A handpiece for a medical instrumentation device is formed with manually deformable ribs on an outer sleeve. The ribs align with conductive surfaces inside the handpiece that make contact with an internal flexible electronic circuit to activate the device when force is applied to the ribs. Removing the force deactivates the device.
Claims4
A medical instrument comprising:
- a cylindrical handpiece;
- an electrical circuit for actuating a medical laser, the circuit including axially elongated contact strips at circumferentially spaced-apart locations within the handpiece;
- axially elongated pads in radial alignment with the contact strips and configured to actuate the circuit when pressed against the contact strips;
- and
- axially elongated ribs located at the outer circumference of the handpiece in radial alignment with the pads, the ribs being manually movable radially inward against the pads to press the pads against the contact strips and thereby to actuate the circuit.
