What is a Holmium 온라인 카지노 사이트?

TheHo:YAG (or holmium) 온라인 카지노 사이트is a high-power, solid-state, near-infrared source that can be fiber delivered. This makes it a popu온라인 카지노 사이트r tool forsurgical applicationsin urology, ort온라인 카지노 사이트pedics, gynecology, dentistry, and more.

Ho:YAG (holmium) 온라인 카지노 사이트s are widely used in surgical applications, and a look at the graph explains why. The graph shows three different things. First, the absorption of light by water in the visible and infrared spectral regions (the blue curve). Second, the range of wavelengths over which fused silica is transmissive (the green area). Finally, the output wavelengths for several different high-power 온라인 카지노 사이트s.

Figure 1.Water absorption (blue curve) in the visible and infrared spectral regions, plus the transmission band of fused silica (green area). The ideal surgical 온라인 카지노 사이트 source outputs where the water absorption is highest within the fused silica transmission band.

All living tissue is essentially water. So, the more that water absorbs a particular 온라인 카지노 사이트 wavelength, the more efficiently that 온라인 카지노 사이트 can heat and remove tissue.

Fused silica is the material used to make optical fibers. 온라인 카지노 사이트s with output wavelengths that are transmitted by fused silica can be fiber delivered. This is a highly advantageous surgical modality.

Thus, the ideal 온라인 카지노 사이트 for fiber-delivered surgical procedures has a wavelength that is well absorbed by water and is also within the fused silica transmission range. Currently, there are really only two 온라인 카지노 사이트s that meet these criteria. The holmium 온라인 카지노 사이트 and the thulium fiber 온라인 카지노 사이트 (TFL). Water absorption at wavelengths around 1000 nm is relatively low, which makes both Nd:YAG and fiber 온라인 카지노 사이트s less useful as surgical sources.

The holmium 온라인 카지노 사이트 was developed several decades ago and has now become the established source for many medical applications. The TFL actually has more desirable properties than the holmium 온라인 카지노 사이트 – in terms of output characteristics, practical features, and cost. But it is a newer technology, and it will take time to complete the studies and regulatory approvals required for it to become a mainstream surgical source. Thus, the holmium 온라인 카지노 사이트 currently reigns supreme.

The longer infrared wavelengths of both Er:YAG (erbium) andCO2온라인 카지노 사이트smean they can’t be fiber delivered. This limits the way they can be deployed for surgery, alt온라인 카지노 사이트ugh they are both widely used for medical applications, particularly in dentistry and dermatology.

 

온라인 카지노 사이트:YAG온라인 카지노 사이트 construction and characteristics

온라인 카지노 사이트:YAG is the abbreviation for an yttrium aluminum garnet crystal doped with 온라인 카지노 사이트lmium (온라인 카지노 사이트3+) ions. Ho:YAG can be used to construct solid-state, pulsed 온라인 카지노 사이트s with output at 2.1 µm.

There are no common diode 온라인 카지노 사이트s which output at the main absorption band in Ho:YAG at 1.9 µm, so these 온라인 카지노 사이트s are typically flashlamp pumped. The Ho:YAG 온라인 카지노 사이트 resonator follows the typical flashlamp-pumped 온라인 카지노 사이트 configuration, and is shown schematically in the figure. Bursts of light from the flashlamp are focused into the 온라인 카지노 사이트 crystal. These supply energy and the crystal then produces pulses of 온라인 카지노 사이트 light.

Ho:YAG 온라인 카지노 사이트s are commercially available in (average) output powers ranging from about 20 W to 150 W. Because of the inefficiency of pumping the 온라인 카지노 사이트 crystal with a broadband (flashlamp) source, these 온라인 카지노 사이트s are relatively power hungry and also generate a fair amount of waste heat. As a result, they typically require 230 V power and water cooling.

The pulsing characteristics from a Ho:YAG 온라인 카지노 사이트 can be varied by changing the way the flashlamp is operated. This provides the surgeon flexibility in controlling exactly the way the 온라인 카지노 사이트 light interacts with tissue.

This variety of commercially available products, together with the large parameter space over which a given Ho:YAG 온라인 카지노 사이트 can operate, enables these sources to support a diverse range of medical applications. Because of this, they are often dubbed the “Swiss Army Knife of 온라인 카지노 사이트s.” Some of the most important surgical applications of Ho:YAG 온라인 카지노 사이트s are outlined here.

 

온라인 카지노 사이트 lithotripsy

온라인 카지노 사이트 lithotripsyis one of the main applications for Ho:YAG 온라인 카지노 사이트s. Here, the 온라인 카지노 사이트 is used to break up a kidney stone that has become lodged somewhere within the urinary tract. 온라인 카지노 사이트 lithotripsy generally provides better outcomes than alternative methods such as shock wave lithotripsy, ureteroscopy, or percutaneous nephrolithotomy (PCNL).

온라인 카지노 사이트 lithotripsy is most commonly implemented in combination with ureteroscopy. A ureteroscope is a long, thin, flexible tube that can be directly inserted into the urethra and then guided through the bladder all the way into the ureter. The ureteroscope contains an illumination source and imaging optics that allows the surgeon to guide it and view the stones.

For lithotripsy, an optical fiber is inserted into the ureteroscope. The Ho:YAG 온라인 카지노 사이트 is focused into the fiber and delivered to the stone through it. The 온라인 카지노 사이트 light is absorbed by the stone to break it up.

In lithotripsy, the ability to vary the output parameters (repetition rate, pulse energy, and pulse duration) of the Ho:YAG 온라인 카지노 사이트 allows the surgeon to employ a variety of methods for stone removal. For example, using lower pulse energies at higher repetition rates typically produces “dusting” (creation of submillimeter-sized stone fragments). Here the intention is to break the stone into pieces small enough to pass on their own.

The use of higher pulse energies at lower repetition rates generates larger debris. In this met온라인 카지노 사이트d, called “fragmentation with extraction” the surgeon then uses a catch basket on the ureteroscope to remove these larger pieces.

 

Prostate surgery

Benign prostatic hyperp온라인 카지노 사이트sia (BPH) is the medical term for an en온라인 카지노 사이트rged prostate. This can cause irritation and difficulties with urination. About half of all men will have some degree of BPH by the age of 60.

Two widely used surgical treatments for BPH are holmium 온라인 카지노 사이트 ablation of the prostate (HoLAP) and holmium 온라인 카지노 사이트 enucleation of the prostate (HoLEP). Both procedures are performed with a resectoscope, which is introduced into the urethra. The resectoscope is a long, thin tube which incorporates viewing optics and water flow channels. It also allows a fiber optic to be inserted to deliver the 온라인 카지노 사이트 beam to the surgical site.

In HoLAP, the 온라인 카지노 사이트 is used to ablate tissue and reduce the size of the prostate. The removed tissue is evaporated, which means there is nothing available for subsequent analysis by a pathologist. This means that the procedure can’t be used to biopsy prostate tissue for cancer screening.

In contrast, 온라인 카지노 사이트LEP uses a different fiber delivery configuration which enables the surgeon to actually cut larger pieces (enucleate) from the prostate. This enucleated tissue is pushed into the bladder using the resectoscope. At the end of the procedure, t온라인 카지노 사이트se pieces are extracted which allows for subsequent analysis.

Because HoLAP utilizes a smaller penetration depth for the 온라인 카지노 사이트 energy, removing a given amount of tissue can take more time than with HoLEP. But HoLAP is essentially a bloodless method which delivers excellent results and quicker recovery times. HoLEP can be used to treat larger sized prostates, and again, provides the benefit of retrieved tissue for pathological analysis.

 

Ort온라인 카지노 사이트pedics

Ho:YAG 온라인 카지노 사이트 are used in a number of different orthopedic procedures. Typically, these are performed using arthroscopy. An arthroscope is another surgical instrument composed of a long, thin, rigid tube which contains viewing optics and an illumination source. It can also accommodate the fiber optic to enable 온라인 카지노 사이트 beam delivery to the surgical site.

The arthroscope is introduced into the body through a small incision. The surgeon locates the area that requires treatment, and typically uses the holmium 온라인 카지노 사이트 to vaporize tissue and correct the problem. This makes it a minimally invasive procedure which speeds subsequent patient recovery and minimizes discomfort.

One example of this is 온라인 카지노 사이트 discectomy. Here the procedure is intended to reduce a herniated spinal disc. Specifically, part of the intervertebral disc has bulged out and is pressing on a spinal nerve to cause pain or numbness. The 온라인 카지노 사이트 is used to directly vaporize the bulged area.

온라인 카지노 사이트-assisted arthroscopic surgery is also used to treat a variety of conditions on joints, such as knees, ankles, and shoulders. Specifically, it can remove scar tissue and bony lesions, vaporize loose material within the joint, and more.
