Why use laser? ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]

Why use laser? - The laser seals nerve endings as it cuts. So the patient will have less pain. ,[object Object],- The laser seals small blood vessels during surgery and speeds up surgery by minimizing bleeding. ,[object Object],- No physical contact except the invisible laser beam. The tissue will not be crushed. ,[object Object],- The laser sterilizes the surgical site as it cuts. Bacteria and viruses are vaporized by the laser during laser surgery. ,[object Object],[object Object],Less bleeding and swelling will result in faster healing ,[object Object],- The beam direction and power can be controlled precisely to remove thin layers of tissue and produce minimal side effects on the surrounding healthy tissue. ,[object Object],All of above factor will greatly reduce the procedure time.

Laser surgery benefits for surgeons ,[object Object],[object Object],[object Object],[object Object]

Laser surgery benefits for surgeons Laser surgery improves many surgical procedures by making them simpler and reducing risk. This enables surgeries that are not practical with conventional methods. ,[object Object],The laser light seals capillaries and small blood vessels as it cuts, thereby dramatically reducing bleeding. This results in a much clearer and drier surgical site. ,[object Object],The focal spot size of the beam may be adjusted down to a small fraction of a millimeter or expanded for a much wider coverage. The laser power may be set for rapid removal of relatively large tissue amounts, or adjusted to remove only one cell layer at a time. ,[object Object],The hemostatic effect of the laser beam and the improved visibility of the surgical field often reduce the duration of the surgery ,[object Object]

Operations Scalpel blade or a nail trimmer is the traditional way of declaws, that was painful and time consuming. Laser surgery to declaw will make cats have little pain One of the CO2 laser features, selectively and gently going through layers of tissue, makes the CO2 laser excellent for ear hematoma due to the small opening needed to drain the fluid. Laser can completely ablate the small tumors lesion and make pets have less discomfort during the recovering time. ,[object Object],[object Object],[object Object],[object Object],CO2 laser can also treat dog neuters due to the advantages of minimal bleeding and less pain. ,[object Object],The laser is particularly good at amputations. Minimal bleeding during the laser surgery allows the surgery to perform much faster.

Thank you Laser will not make a practitioner a better surgeon; it will, however, allow a good surgeon to do surgery in a way that helps their patients and owners.
