Cleaning Instructions for Picasso Plus and Picasso Lite Plus Surgical Handpiece and the
Strippable Fiber Optic Cable
The cleaning process is intended to remove blood, protein, and other potential contaminants from the
surface and crevices of reusable accessories. This process will also reduce the quantity of particles,
microorganisms, and pyrogens present. Cleaning should be performed prior to sterilization and must be
conducted only by qualified office personnel trained to perform the procedure and handle the Picasso
Plus and Picasso Lite Plus Fiber Optic Delivery System.
Wear protective gloves when handling the contaminated delivery system. To disconnect the delivery
system, follow the instructions for delivery system assembly presented in the section “Picasso Plus and
Picasso Lite Plus set-up” under “Set-up Information”.
Disinfection Instructions for the Strippable Fiber Optic Cable
• Transport the delivery system to a decontamination/sterilization work area.
• Take the fiber and strip 1 inch (2.5 mm) off of the distal end of the fiber using the fiber cleaver. Make
sure the part that has debris is removed entirely. Dispose of the contaminated fiber tip accordingly.
• Prepare a sterilizing and disinfecting solution of a CaviCide™ equivalent and submerge
approximately 12 inches (30 cm) of the fiber’s distal end into the solution for 5 minutes. For high
level of disinfecting, immerse the fiber end for 30 minutes at 68°F (20°C).
• After this process is completed, thoroughly rinse and dry the fiber.
• For disposal of CaviCide™ equivalent disinfecting solution, please follow the manufacturer’s
instructions. CaviCide™ is not a product or trademark of AMD Lasers.
Steam Sterilization for Picasso Plus and Picasso Lite Plus Surgical Handpiece
Before sterilization, the handpiece must be cleaned and disassembled. For cleaning, follow the
procedures previously described. To disassemble the handpiece from the fiber optic cable, carefully
loosen the handpiece base and slide handpiece off of the fiber optic cable.
The process of thermal sterilization with saturated steam under pressure is carried out in an autoclave.
To perform this procedure, follow these step-by-step instructions:
• Disassemble the handpiece, remove the rubber insert and store in a secure location for reassembly
(do not autoclave the rubber insert).
• Place the handpiece and interchangeable tips inside a single wrap self-seal autoclave pouch.
• Remove autoclave tray and place pouch(es) on the tray.
• Place tray inside the autoclave chamber and set controls to the following values: Temperature:
250°F (121°C), Pressure: 15 PSI (1 Bar), and Time Cycle: 30 minutes
• At the completion of the autoclave cycle, remove the tray and let the handpiece cool and dry. There
is no specific requirement for the drying time.
• Attach the handpiece and the fiber optic cable to the unit for the next procedure.
CAUTION: DO NOT PLACE OR STACK OTHER DEVICES ON TOP OF THE FIBER OPTIC CABLE.
Disposal of Used Fiber Tips, Non-Working Fibers, or Disposable Tips
Any portion of the fiber optic cable or disposable tip that comes in contact with a patient should be
treated as a biohazard material and properly disposed of as governed by applicable laws and
regulations.
Clinical Applications
To efficiently remove tissue, it is imperative to understand the nature of the Picasso Plus and Picasso
Lite Plus. Each laser operates unlike traditional devices. The techniques mentioned below must be
practiced and perfected to ensure efficient operation. Please study this section carefully, practice on
sample tissues, and attend a quality diode laser training seminar before using this device in a clinical
situation. The Picasso line of soft tissue lasers are designed for a number of surgical and non-surgical
procedures. (See “Indications for Use”).
Only licensed professionals, who have successfully completed Picasso training and are certified in the
use of Class IV lasers, have read and understand this manual, and know how to correctly operate the
system, should use this device.
The use of the Picasso line of lasers can be used in a contact and non-contact modes. Surgery requires
the initiation of distal 2–3 mm of fiber optic tip or fiber. Articulating paper is supplied with each laser for
initiation. This initiation focuses laser energy to the tip.
Non-initiated tips are used in hygiene mode for the treatment of some ulcers and for other therapeutic
reasons.
Soft-Tissue Surgery: Contact Mode
Cutting and coagulating soft tissue procedures can be utilized with either surgical handpiece or the
multi-tip fiber handpiece and a disposable tip. The fiber tip or disposable tip must be initiated for cutting
to occur. Operator should start with the lowest energy possible to achieve desired results. Disposable
tips may not be used for procedures requiring more than 3.5 W.
Diode energy is highly absorbed by hemoglobin. The darker the pigment is the less energy is required to
cut. Fibrous tissue requires more energy to cut. Most surgeries can be performed in the Speed or
Comfort modes and a range between 0.5–3 W with either CONTINUOUS or PULSE MODES. Operator
should try to use the least amount of power (WATTS) to achieve desired results.
When tissue builds up during a cutting procedure, remove the tissue using a clean gauze pad. Consult
the accessories index for a complete listing of fibers and tips.
When procedure is complete, turn off the laser, appropriately dispose of the tip, clean handpiece with
CaviCide™ or similar material, cover with protective cover, and place the handpiece in the holder.
Always clean and use a new tip prior to use.
Description of Laser Operation Modes
Picasso Plus and Picasso Lite Plus have two modes of operation: CONTINUOUS and REPEAT (or PULSE)
MODE. In CONTINUOUS mode, the laser will deliver output radiation at the power level specified by the
user for as long as the foot switch is held down. In REPEAT / PULSE mode, the laser will deliver output
radiation at the power level specified by the user and in a pulse format defined by the user for Picasso Plus
