A surgical navigation system is an image-guided intraoperative location system, whose main function is to provide the surgeon with a real-time feedback of the location of the surgical instruments in relation to the anatomy of the patient.  Therefore, it helps the planning and execution of surgical procedures in the operating theaters, guiding surgical instruments such as the electric scalpel. There are two types of navigation system: Optics and electromagnetic, both provide combined flexibility and efficiency in a space-saving design in the OR.

A surgical navigation system is a medical team based on the principle of high-precision stereoscopic vision, and which has now become an essential team for the development of computer-assisted surgeries, as they are responsible for guiding the surgeon's movements during surgery, showing the real-time position of each anatomical instrument and structure.  This device allows the use of digital images in surgical procedures, thus providing surgeons with the opportunity to carry out preoperative planning and an effective use of the instruments during surgical procedures.

A surgical navigation system is a medical equipment that allows visualizing the anatomy of the patient during a surgical procedure and accurately tracking the location of the surgical instruments used. The use of these equipment during different surgical procedures provides greater precision, the performance of less invasive procedures and helps to obtain better surgical results.

An electrosurgery unit or electrosurgical unit is a medical device that transmits energy in a controlled manner to living tissue for surgical purposes in order to cut, coagulate, fulgurate, and desiccate tissues, depending on the parameters established by the medical operator

The electrosurgical or electrosurgical unit, also called an electrosurgical unit, is a medical device that uses electrical phenomena to produce heat; its objective is to coagulate, glow, desiccate or cut tissues, depending on the established parameters. The production of heat is achieved through the passage of an oscillatory electric current, concentrated in a small area. The smaller the space in which the current flows, the higher the energy density at this point, resulting in higher and higher temperatures.

The electrosurgical unit is a medical equipment capable of transforming electrical energy into heat to cut or coagulate tissues and cauterize them simultaneously, using currents that develop at high frequencies usually above 200,000 Hz. In other words, this equipment is responsible for generating high-frequency alternating current from low-frequency electrical currents, with the aim of achieving a desired thermal effect on a biological tissue.

The electroscalpel is a device that is present in approximately 80% of surgical processes, through electrical phenomena it is able to coagulate, flare, cut tissues according to established parameters, this instrument produces heat through an oscillatory electric current, concentrated in a small area; the current it uses is taken from the electrical network and transformed into direct current.

Phototherapy is a therapeutic technique used in medicine to treat skin diseases such as psoriasis and vitiligo, and neonatal hyperbilirubinemia clinical pictures where light is used because of its anti-inflammatory capacity or to contribute to reduce serum bilirubin levels respectively.

Phototherapy or light therapy is the reference treatment for hyperbilirubinemia in babies, known as neonatal hyperbilirubinemia, for which fluorescent white light is frequently used, although blue light can also be used, with a wavelength of 425 to 475 nm, being this one more effective for cases of intensive phototherapy.

Phototherapy is a therapeutic measure in which light is used, specifically ultraviolet light (UV) because UV radiation has anti-inflammatory action, for the treatment of dermatological inflammatory and neoplastic skin diseases. The use of phototherapy dates from the early twentieth century and from there have emerged several modalities being the commonly used UVA therapy (340-400 nm), PUVA (Psoraleno + UVA), broadband UVB (280-320 nm) and the most recent the narrow band UVB (311 nm).
