medical use

1. Laser Therapy Futuristic Approach in General Surgery Dr Qasim Minhas Specialist General Surgery Hamdan , Abudhabi

2. Define Laser Physics behind Lasers Principles of Lasers-Tissue Interaction Clinical applications in General Surgery Our experience with Safety, Quality, Efficiency of lasers Overview

3. L ight A mplification by the S timulated E mission of R adiation Laser surgery is a type of surgery that uses special light beams instead of instruments for surgical procedures LASER

4. Laser consists of Medium enclosed between two parallel mirrors, one of which is partially reflecting and partially transmitting The medium is Excited by an electrical source until the number of atoms in the excited state Powerful, cohesive beam of photons to be released as Laser light to achieve desired effects Physics

5. Er;YAG ND;YAG CO2 Argon Diode Types of Laser

6. Photo thermal Photo dynamics , infection, bacteria Hemostatic Vaporization Coagulation Debulking and necrosis Mechanism of Action of Laser

7. Factors related to Laser Wave length Mode , Pulse/ Continuous Output Power , Watts Frequency intervals / duration Peak Pulse Energy transferred to tissues Distance from the target area Efficiency Cost effectiveness Laser – Tissue Interaction

8. Factors related to Human tissue Structure, Site, Size of tissue Water content Thermal conductivity Heat capacity Density of tissue Absorption, Scattering or reflection of emitted energy Hb , Pigmented content Laser – Tissue Interaction

9. Minimally Invasive Procedures Less operative time Less pain, bleeding, less tissue handling OPD/ Day Care surgeries, less time in Hospital Speedy recovery Less post operative complications, side effects Less infection incidence Better wound healing results Less risk to patient health and safety Merits of using Laser

10. High cost Laser equipment Surgical skills Team works Ensure Safety and Quality of system Demerits of using Laser

11. European certified and manufactured It’s the most versatile, efficient and universal medical laser in the medical facilities today This highly compact Diode Laser features the combination of two wavelengths, 980 nm and 1470 nm, offering a variety of tissue interactions Laser System

12. The 980 to 1470 nm wavelength provides high absorption in hemoglobin, making it well suited for Incision, excision, vaporization, hemostasis, and coagulation of soft tissue Due to the absorption properties, the emitted laser beam does not affect the surrounding tissue Laser System

13. Each wavelength can be individually selected or blended together to offer the perfect desired tissue effects Clinicians can perform laser surgery selectively, with settings individually tailored to the tissue type and the desired tissue effects and thus corresponding to the therapeutic needs Laser System

14. Surgical team Aware of different Laser delivery systems, selection of proper wave lengths, proper laser parameters and their tissue effects to achieve desired clinical outcomes Surgical Team experience and facile approach with the technique and technology is of utmost importance Quality, Safety, Efficiency

15. Proper assistance Surgery Team should work together frequently and should practice and inspect equipment Team members should be able to assemble and troubleshoot the instruments and delivery system Quality, Safety, Efficiency

16. Knowledge, Skill, Team work All team members must maintain constant vigilance when using lasers All team members should be aware of three dimensional topography and anatomy of the operative site Quality, Safety, Efficiency

17. Clinical outcome of laser surgery depends on availability, skill, judgement, clinical surgical awareness and the sense that a particular tool Feels right or Works well for a particular task in the hands of experienced surgeon is most important thing Quality, Safety, Efficiency

18. As laser technology continues to improve in precision and safety their applications in medicine are sure to expand to continue providing safer outcomes, more optimal clearance of disease, and improved patient satisfaction Future of Laser

19. Question 1 Laser stands for light amplification by stimulated emission of radiation. Correct Answer True Question 2 Every Laser Delivery system consists of Medium. Medium can be solid, liquid, or , gas Correct Answer True Question 3 One of the benefits of using Lasers is that operating surgeon does not like any specific training Correct Answer False Question 4 Filac probe used in anal fistula is 360 degree ring light laser Correct Answer Yes
