Abstract

The new laser device contains fiberoptics cables one of them is to keep the temperature of the body as it is and the other is to keep the temperature of the brain as it is.The third is to decrease the temperature of the spinal cord till the end of the operation. Adding to this the use of Helium element to decrease the temperature and the Ferion Gaz for the same reason to the Diode Pump to excite freesing. Previous inventions don't touch the spinal cord but this device will help the surgeon to make operation easily. The name is Ouda laser.

Description

Surgical Laser Device

Technical Field

The domain of use is the medical domain , we will use it in spinal cord surgery . Neurosurgeon make operations in a very sensitive part of the human been , very sensitive body , he uses scalpel , scissors , cottary , Hoc and frame for fixing head , bone drills and device for swe the bone . The new what we need to add at this domain is the laser surgery and this to make operations in the spinal cord . New elements are using the Helium element to decrease the temperature and the Ferion Gaz .

Background Art :

Lasers have become powerful tools , used in almost every aspect of technology .Medical lasers have never become the " magic ray " that some had hoped . Laser applications in medicine and surgery have similarly envolved , they have become powerful tools in clinical practice . Today , there are many medical laser systems available . They all use the principal of selective photothermolysis , which means getting the right amount of the right wavelength of laser energy to the right tissue to damage only that tissue and nothing else . Most medical laser devices deliver only one wavelength of laser light and the laser surgeon must choose the right wavelength for the specific tissue involved . Some lasers can be doubled , and deliver tow wavelengths of laser light , and a very few are tuneable over a narrow range of wavelengths All medical lasers allow the laser surgeon to adjust thew power setting and duration of the laser pulse . As a general rule , the length of the laser pulse is as important as the wavelength or the power setting in determining its medical use . Lasers can operated in continuous wave or pulsed mode . Continuous wave lasers emit a steady beam for as long as the laser medium is erxcited . If this steady beam is heald on tissue longer than the thermal rewlaxation time , excessive heat will be conducted into normal tissue , which may delay healing and increase scarring . All CW lasers may be pulsed , either mechanically using a shutter , or by electronic or photonic means . Pulsed lasers emit light in individual pulses , which may be long -pulsed or short-pulse . Q-Switching allows the laser to store energy between pulses , enabling very high power output .There are many kinds of medical lasers which are used currently .

Medical lasers are not magic - they are only tools and one should always select the right tool for the right job .

Kinds of Medical lasers :

1-CO2 laser .

2-Argon laser .

3-Yag laser.

4-Ruby laser .

5 -Alexandrite laser .

6-Pulsed Dye laser .

7-Cooper vapor laser .

8-Diode lasers.

9-Excimer lasers .

10-intensed pulse light .

When we talk about spinal cord . We talk about cells of a very special place and a very sensitive place and we have to be careful when we operate it . I choose Diode laser to developp it and use it in spinal cord surgery and it doesn't affoard the high temperature .

Diode lasers are solid state devices . The familiar " laser pointers " are in fact diode lasers , it uses the pulsed mode and for periodontal surgery .

Other applications include treatmentof leg and facial veins .

Diode lasers are also used to excite or pump more traditional laser media , for example Yag rods . Because of their relative simplicity and low maintenance requirements , Diode lasers and diode pumped solid state lasers will be used more in the near future .

The problem in the background Art :

There is no problem in the previous art . There are a developed medical tools but need more development to make more operations in sensitive places as the spinal cord . The problem is that the spinal cord can't affoard the high temperature either the wavelength is pulsed or continuous . Some think to make operations without touching the spinal cord . But this is false . How to make operation without touching the part which need to be operated . This device can't operate the spinal cord because of heat and because the brain can't affoard the high temperature and we need to avoid the influence of heat on the body and keep it as it is . The old device hasn't fiberoptic cables to keep[ the temperature of the body as it is .

This is the reason of adding fiberoptics with thermostats to decrease the temperature .And add the Helium Gaz to decrease the temperature . Disclosure of Invention :

The new laser device use a crystal rod as the lasing medium . Lasers may be operated in continuous , pulsed , Q- Switched mode or pump . This particular medical device is usually capable of continuous pulsed delivery .

And it is through fiberoptic cables and through Q\Switched and this is to keep very high power through an articulated arm . Adding to this cables with themiostate to keep the temperature of the body as it is , the temperature of the brain as it is and the third is to pump coldness to the spinal cord and this is to avoid the laser beam and the heat . We want to avoid the influence of the high temperature on the body and keep it as it is , the old device hasn't fiberoptic cables to keep the temperature of the body as it is .

For this we have to add these fiberoptics which contains Thermostate to decrease the temperature . This laser is using to emit the near- infrared light in the 800-900 nm range .

Their principal application is in millisecond -range pulsed mode . It's used for periodontal surgery , as for example for hair removal . Other applications include treatment of leg and facial veins . Diode bars are also used to excite or pump more traditional laser media , for example Yag rods . Because of their relative simplicity and low maintenance requirements , Diode lasers and Diode - pumped solid state lasers will be used more in the near future as more wavelengths become available in medical domain and we have to add Ferion Gaz ( Halogen + Carbone ) to these pumps .
