Application of sapphire crystal in medical field

Today, sapphire micro scalpels are produced in Switzerland, China, Ukraine, and the United States. Regular scalpels and sapphire micro scalpels are produced in Ukraine.

The transparency of the sapphire scalpel blade enables a unique surgical procedure consisting of directing a single-mode laser beam through the blade through a flexible optical fiber to the cutting area (Figure 1.28).

In addition to the treatment, treatment, effects (sterilization, painless, anti-inflammatory, anti-edema, immune correct, allergy-reducing effects) and better visual effects at the edge of the blade, This scalpel has another important advantage. It enables simultaneous illumination and determination of the correct location of capillaries, meridians, and other anatomical structures, both in the cutting area and within the range of blade advancement, as well as more effective control of the depth of cut. The effectiveness of interior lighting can be created. Due to this light-reflecting property, if a micro-defect is formed on the cutting edge, it can be immediately revealed to the surgeon.

Clinical results prove that compared with traditional surgical instruments, sapphire tools shorten the operation time, speed up the repair process, reduce the recovery period and limit the probability of infection. This provides a better clinical effect on the recovery of Shen meridian, lymph and other functions. Sapphire tools can be used to perform surgical, ophthalmic, cosmetic and surgical treatment of benign tumors (papillomas, dermatomas, gingival tumors) in the maxillofacial region [63,64].

Sapphire applications in medical devices. Sapphire is chemically purer and more inert than most structural materials. Blood components are not damaged when in contact with the sapphire surface polished to a high finish. Sapphire can withstand considerable laser loads while still maintaining good IR transmission in the infrared region of the spectrum. For example, at the wavelength of Er:YAG-laser radiation (2.94 μm), the absorption of sapphire is much smaller than that of glass, and sapphire can withstand loads higher than 1 kJ/cm2 without damage [65]. These properties determine the use of sapphire in medical devices such as:

Transfer pumps for blood and other substances (tubes, plungers, valves, pump housings)

Endoscopes (different shaped blades)

Laser surgery: Nd:YAG‐ and Er:YAG‐ based instruments, laser IR scalpels (conical sapphire contact tip for dissection, hemispherical tip for evaporation and tissue coagulation in contact with light guide windows cylindrical tip end).

Equipment for obtaining high-purity medical preparations (crucibles, test tubes, tubing, reactors).

The fields of application of sapphire are constantly expanding. For example: the concept of "Sapphire Room" should be mentioned. A medical project has recently been proposed (but not yet implemented), dedicated to creating a special room clad in artificial or natural sapphire. Medical rooms that generate electromagnetic fields are known in different configurations depending on the enclosed space. According to Patent No. 2030909 of the Russian Federation, the crystalline field of sapphire can have an effect on the biological field of the human being, therefore, stimulate the intrinsic factors of the patient to overcome certain diseases or help relieve symptoms.
