When it comes to surgical procedures, selecting the appropriate kind of surgical admittance or access for any particular condition will always be an expertise of its own for any surgeon. This choice of deciding on making a particular incision is based on a variety of aspects, for example, the site of surgery, associated anatomical structures, effortless accessibility, a lesser number of difficulties, faster recovery as well as minimal scars after the surgery is complete. However, many of these choices are probably not achieved and then the surgeons have got to be able to make an expert judgment so as to determine what is most beneficial for the patient’s condition and then take quick action so as to be able to save that patient’s life.
Laser surgery is a surgical procedure that makes use of a laser in order to cut tissue as an alternative to using a scalpel. For example, using a laser scalpel in standard conventional surgery as well as soft tissue laser surgery, wherein the beam from the laser vaporizes the soft tissue by using higher water content. Laser resurfacing is a procedure through which molecular bonds of any material can be dissolved by using a laser.
Laser surgery is commonly performed on the eyes. LASIK is a technique utilized to take care of near as well as far-sightedness with regards to vision. Photorefractive keratectomy is a technique that completely and entirely enhances the shape of the cornea by using an Excimer laser to get rid of a minimal quantity of tissue.
Green laser surgery is commonly used with regards to the treatment therapy as well as the decrease associated with enlarged prostates. Surgery with lasers is a great deal more safe and free of risks as compared to normal surgery. This is so, as green laser surgery will not make any actual physical contact, therefore there is no chance of an infection spreading.
The laser scalpel (knife) can be described as a scalpel intended for surgery, cutting or even ablating living biological tissues by means of the energy of laser light. With regards to soft tissue laser surgery, the laser beam vaporizes or ablates the soft tissue with the help of high water content.
LASIK and LASEK are procedures in ophthalmology that are carried out by Excimer lasers to help change the shape of the cornea.
Vascular surgery, circumcisions as well as neurosurgery are a few of the other surgical fields in which a laser scalpel is commonly used. These days, CO2 and YAG lasers are being used widely. However, the positive aspects associated with utilizing the high-priced free electron lasers are now being researched. With regard to research use in cell biology, unique laser micro-scalpels are able to make cuts that are smaller as compared to a single cell.
With regard to soft tissue laser surgery, the interaction of laser light along with the soft tissue offers a more unique approach to surgery. An extremely focused laser beam vaporizes soft tissues using the high-water content. Lasers can make extremely small incisions whenever the laser beam is targeted on the tissue. The focal spot size could be as tiny as 0.1 mm, however the most common size used during practice is 0.4 mm. Whenever the laser beam is defocused, the power of the laser light focused on the tissue decreases, therefore it could be used for cauterization of smaller blood vessels as well as lymphatics, consequently decreasing post-operative swelling.
A laser beam provides a natural sterilization effect as it evaporates bacteria, fungi and viruses, which in turn results in a reduction in local infections. The most important effect is that the laser beam reduces post-operative discomfort by way of sealing the nerve endings. In laser treatments, ‘Soft Tissue Surgery’ is separated from the ‘Hard Tissue Surgery’ as well as ‘Laser Eye Surgery’ by the laser type utilized in a specific kind of laser surgery.
Surgical lasers in hard tissue surgery are dominated by the Er:YAG lasers that operate at wavelengths of about 3,000 nm. Laser Eye surgical procedures make use of Excimer lasers within the Ultra violet range of wavelengths. In contrast to several solid-state as well as diode lasers within the visible and infrared wavelength range, the CO2 laser wavelength of 10,600 nm is highly absorbed by the in-vivo soft tissues that contain water. Furthermore, contemporary CO2 laser technology tends to make these lasers a lot more affordable as compared to solid-state Er:YAG lasers, that also include a wavelength which is highly soaked up by water. Due to their wavelength and precision, the CO2 lasers continue to be the dominating lasers for soft tissue surgical procedures.
Surgical laser systems usually are separated not just by their wavelengths, but also via the light delivery system, flexible fiber and certain additional factors.
The soft tissue laser surgery is utilized in a wide range of applications, which include General surgery, Dental treatment, Neurosurgery, ENT, Maxillofacial Surgery and also surgeries that fall under the veterinary surgical fields.
