Why our Urology fibers are called Scope Safe

Posted by Kevin Gallagher on January 15, 2013 (0 Comments)

 

Flexible Ureteroscopes are a big investment, and repairs are very expensive  

In urology, holmium laser fibers are passed through various types of ureteroscopes, both flexible and rigid, then laser energy is fired into the laser fiber.  If the fiber is compromised, a small perforation in the instrument channel of a flexible scope will cause fluid to leak into the internal part of the scope and ruin the optics.  This can be noted by a dark or discolored optical bundle.  Flexible scope repairs can cost you up to half the cost of a new ureteroscope.  Our Scope Safe fibers will help to minimize these expensive events!

How can laser fibers cause Ureteroscope damage?  

The most common cause of ureteroscope damage is from everyday use of other manufacturer's laser fibers. Flexible scopes with a fiber in the instrument channel are flexed up to 270 degrees in tight radius bends.  When laser light is slightly defocused, stray laser energy is allowed to launch into the fiber cladding and travels down the cladding and exists at the tight radius bend, burning a hole through the fiber cladding and the instrument channel of the ureteroscope!

  

What design changes make Scope Scope™ superior to other fibers?

For cases where stray laser energy is not perfectly focused on the silica fiber core, Scope Safe™ laser fibers features a patented two-stage filter, designed to prevent stray energy from launching into the cladding, thus safe-guarding your expensive flexible ureteroscope.   Scope Safe™ fibers are true to their name, and will save you money in costly scope repairs!

Scope Safe™ fibers are compatible with many popular laser systems offered by: Coherent, Deka, Lumenis, Dornier, NewStar, and other lasers systems using standard SMA 905 connectors. 

Scope Safe fibers compare favorably to other brand fibers, such as: Accuflex, SlimLine, SlimLineEZ, Flexiva, Dornier, MaxiFlex, ForeTec, SureFlex, EndoBeam, Convergent, OptoLight, and Quanta. These are registered trademarks of fiber marketers: Boston Scientific, Lumenis, Olympus-ACMI, Bard, Cook, and Quanta. 

Scope Safe™ fibers are available in micron sizes: 200, 272, 300, 365, 550, and 1000.  All fibers 200 through 550 are made standard in 3 meter length; 1000 micron fibers come in 2.5 meter length.  Custom lengths are available upon request.  All are packaged sterile, and are coiled in a convenient dispensing hoop, which eases fiber handling in the sterile field. Scope Safe Fibers come Single Use, or Reusable.

Money Back Guarantee:

Scope Scope™ is a Premium brand Holmium Laser Fiber, and to our new customers we offer a money Back guarantee.  Try a box of three fibers – and if Scope Safe™ Premium Laser Fibers do not perform as specified, you will receive a full box refund upon the return of your unused fibers.

I had a potential customer come to me the other day and say, "I love your optics but another manufactures said they are the only company that can mount their loupes on Rudy Project frames".  Well.....Heine's S-Frames are designed and built by Rudy Project and are similar in style to the Rydon style frame.  Below are a few pictures to illustrate my point.

Heine was the first company to mount loupes to Rudy Project Glasses:

A word about Rudy Project sport glasses:

Rudy Project is an Italian leader in optical sportswear as well as high-tech sunglasses.  Many cycling race teams wear Rudy Project eyewear in the largest sporting event in the world, "Le Tour De France."  Rudy Project's founder, Rudy Barbazza, strongly believes that you can create eye protection from advanced materials and technology and still make it pleasing to wear. 

Heine's 2.5X loupes mounted on S-Frames are an example that form and function can be acheived in an aesthetically pleasing package!

Fox Diode Laser

FOX 980nm Diode Laser

The Fox 980 Laser uses diodes to generate laser energy in the 980 nm wavelength and is transmitted via a quartz laser fiber.

Basics of laser application

The intended effect of the laser application is based on the interaction of the radiation with the tissue components. The laser radiation is absorbed, scattered or reflected by the tissue. Air has only little influence on the FOX radiation and therefore the interaction between air and the FOX radiation can be neglected. Reflection plays a major role with metal, glass and other reflecting surfaces.

When we apply the FOX radiation to tissue the reflection is not dominant. Nevertheless it is not zero! When the radiation is scattered in the tissue, it does not influence the absorption. Absorption is mainly responsible for the efficiency of the laser radiation. Absorption means that the FOX laser radiation is converted mainly into heat, which causes the desired effects (coagulation / vaporisation).

With low energy density (big laser spot or low power) the heat which is achieved in the tissue can cause heating of the tissue. The smaller the spot size is, or the higher the power is set, the warmer it gets. There is a limit, when the tissue no longer tolerate the heating, the tissue proteins denaturate, and coagulation occurs. The next limit is achieved when tissue water (intra and extracellular water) suddenly evaporates (> 300° C). Tissue is fragmented and destroyed. Cutting / evaporation is achieved.

Tissue cutting always needs high energy densities (high power or small spot size). At the cutting edges, respectively beside the evaporation zones the tissue is always affected by the heat (coagulation). The positive effect and advantage of the laser use is that this can stop bleeding from cut vessels (haemostasis). The negative effect is caused directly at the cutting edge where more than 150° C occur. There is a development of carbonization, created by burned carbon, which is toxic and prolongs the healing of the wound.

To avoid extended collateral damage (carbonisation and coagulation) at the cutting edges the application mode of the laser can be modified to a pulsed mode, which causes less damage. In continuous mode the laser permanently emits radiation. In pulse mode the tissue can cool down between each laser pulse and therefore the side effects of the heating can be reduced.

Working Distance for Surgical Loupes & Dental Loupes

One important consideration in binocular loupe selection for the health care practitioner is working distance (W.D.)  In addition to properly magnifying the subject, loupe wearers can work long days while minimizing neck strain and possible later visits to the chiropractor.  Whether sitting or standing, upright posture with minimal bending at the waist, hunching of the shoulders, or flexing of the neck is preferred.  


Fortunately, the higher quality loupe manufacturers such as HEINE offer loupes with varying W.D.  Once the proper magnification is selected, for example 2.5x, the user should consider the appropriate W.D.  The HEINE 2.5x HR loupe is available in three W.D.'s: 13" (340mm); 16" (420mm), and 20" (520mm).   Each of these optics has a range of focus, so the center of the focal range is the W.D.  This means that the image will also be in focus +/- about 3.5" from the W.D. (this varies slightly per lens magnification).  Therefore, a lens with a W.D. of 16" will be in focus from the eye for a distance of approximately 13" through 19".    This is a very pleasant range, and the 16" model is far and away the most popular W.D. for both surgical and dental specialists alike.  


Situations can vary, so it is recommended that you work with a partner to help determine your personal W.D.  Assume your typical position and posture when performing actual procedures.  Whether sitting or standing, assume a position that you are comfortable with for longer cases.  Also consider factors such as your standing height (are you taller or shorter), the length of your arms, and the length of torso while sitting.  Simulate your typical working position, but err on the side of maintaining proper posture.  Remember that loupes can prevent unnecessary stooping and hunching, and this may prolong your work day, and possibly your career!  Have your assistant utilize a longer ruler, or tape to measure, from eye to subject, where your typical W.D. falls.  Also remember that quality Loupes,  such as the HEINE 2.5x  13", 16" or 20" W.D. have variability of +/- a few inches, so you will definitely have a good range of focus. 


After you acquire your selected loupes, it is recommended to wear them for a few cases before judging if they are right for you.  HEINE offers a 45 Day Money Back Guarantee, so occasionally a wearer will want to switch from one working distance to another prior to settling on his/her desired specification.  This is not a problem, and we will be happy to accommodate your specific needs. 



Sincerely, 


MDLoupesPro
