Purpose of the development: The invention relates to medical technology, namely surgical instruments for influencing the soft tissue for diagnostic or therapeutic purposes.

Recommended application field: Using the proposed sapphire scalpel to perform laser eye surgery is best for neurosurgery, ophthalmic, cosmetic, gynecological, general surgical operations, and can also be used in patients with cancer.

Technical characteristic: Sapphire laser scalpel for operations consists of a straight working portion formed as a stainless steel tube outer diameter of 10 mm and a length of 150 mm, pressed into a massive tube cannula , wherein the handle has a tail portion cut at an angle 90 °, introduced into the lumen of the tube an optical fiber that terminates at an end portion of the cannula , which is screwed onto the mandrel . Additional settlement of high-intensity laser radiation of infrared diode laser with a wavelength of 810-980 nm for the effects on the soft tissue.

Advantages over analogues: Complex inventions for laser eye surgery and treatment of cervical pathology is effective because it allows at least traumatic lesion to eliminate interference, significantly reduce the duration of treatment of patients and reduce the dose of drugs. Using the proposed invention makes it easier and greatly reduce the interference and reduce the incidence of postoperative infectious complications.

The development stage readiness: Tested experimental exploitation order

Description of the development:
()
Using the proposed sapphire scalpel to perform laser eye surgery is best for neurosurgery , ophthalmic , cosmetic , gynecological, general surgical operations, and can be used in cancer patients as worksurface sapphire not only directly dissecting the soft tissue , but the sighting leads to pathological tissues low-intensity and high-intensity laser radiation, which allows simultaneous dissection of tissues to carry out coagulation of tissue and blood vessels ( hemostatic effect ) , evaporate the diseased tissue ( vaporization ) , sterilize the area of impact and accelerate regression of inflammation and reduce the period of tissue repair in the postoperative period . Complex inventions solves problems sapphire scalpel and improve its compatibility with high-intensity laser radiation and adaptation effects on the soft tissue , which would use it to coagulation and vaporization of soft tissue in the affected area ( zone of influence ) . This eliminates or significantly reduces necrotic zone , the amount of blood loss , small lesions can vaporizovat ( evaporate ) without significant damage to surrounding healthy tissue , which is particularly important during the manipulation of the cervix , and also allows you to fully comply with the requirements of ablation - antiblastiki and antiseptics , prevent the occurrence of cervical syndrome coagulated . Also reduced the time of surgery or manipulation ( hemostatic effect of high-intensity laser , local evaporation abnormal tissue ) , reduced incidence of postoperative infectious complications (laser sterilization of wounds ) . Sapphire laser scalpel for operations consists of a straight working portion formed as a stainless steel tube outer diameter of 10 mm and a length of 150 mm, pressed into a massive tube cannula , wherein the handle has a tail portion cut at an angle 90 °, introduced into the lumen of the tube an optical fiber that terminates at an end portion of the cannula , which is screwed onto the mandrel . Lateral surface of the cannula has a bore and a threaded portion . Grooves for comfortable fastening of your fingers . The threaded portion is designed for releasable attachment mandrel sapphire blades . In scalpel handle entered the optical fiber which is subsequently conducted through the elastomeric tube supporting a cannula hub shoulder with a diameter three elastomeric washer having an axial hole is less than the outer diameter of the optical fiber. Due to mismatch of diameters washers are held in the optical fiber and to change their position , it is necessary to apply force in the axial direction of the fiber. Polished fiber end after fixation should be at the end of the cannula , which is wound mandrel . Drift sapphire sapphire blade allows you to record different shape and size . Drift sapphire scalpel expander is used to record sapphire scalpel with different length and shape of the work piece. To establish a sapphire mandrel one of its ends is attached to the end surface of the U-shaped element , with the possibility of transmission of laser light therethrough . Elastomeric tube is inserted into the cannula extending from the auxiliary portion of the sleeve with the shoulder and protects the optical fiber from mechanical effects at the exit point of a pen sapphire scalpel.
