Novel super-energy-gathered laser scalpel

Abstract

The invention discloses a novel super-energy-gathered laser scalpel. The scalpel comprises an outer shell, a laser tool bit, a water-cooling and air-cooling sleeve, a cooling positioning device, a composite mirror body assembly and a smoke exhaust assembly, wherein the laser tool bit is detachably mounted at the front end of the cylindrical outer shell; the water-cooling and air-cooling sleeve comprises a water-cooling sleeve and an air-cooling sleeve which are matched and clamped; the water-cooling sleeve and the air-cooling sleeve are both arranged in a hollow accommodating cavity of the outer shell; the front end of the cooling positioning device is sleeved in the water-cooling sleeve, the middle section of the cooling positioning device is sleeved in the air-cooling sleeve, and the rear section of the cooling positioning device is wrapped by a bunching sleeve; the composite mirror body assembly comprises a biconvex lens and a plano-convex lens which are respectively clamped in theair-cooling sleeve in parallel; and the smoke exhaust assembly comprises a smoke exhaust pipe embedded in the cooling positioning device and a smoke adsorption assembly. The novel super-energy-gathered laser scalpel is provided with the cooling positioning device, the composite mirror body assembly and the smoke exhaust assembly, therefore, rapid cooling of the lens part is realized, and the composite mirror body can gather and increase laser and discharge smoke; and normal operation of laser surgery is improved.

Description

technical field [0001] The invention relates to the field of laser surgery, in particular to a novel super-focused laser scalpel. Background technique [0002] Laser scalpel, using the characteristics of high concentration of laser energy, uses it as a surgical "knife" used in surgery, and uses laser instead of scalpel as a medical device for surgery. Laser has unidirectionality and high energy density, and can cut body tissues by using its thermal effect, optical effect and electromagnetic effect. With laser knife for surgery, the incision is smooth, less bleeding and less prone to infection. Commonly used carbon dioxide laser knife, argon laser knife and so on. [0003] The laser scalpel in the prior art uses a mechanical light guide arm or an optical fiber to transmit laser light, irradiates tissue with laser light, and the water in the tissue or tissue absorbs the laser energy and converts it into heat, thereby vaporizing the tissue for cutting and coagulating blood at...

AI Technical Summary

Problems solved by technology

[0007] The present invention provides a new type of super-concentrated laser scalpel to solve the problems of laser energy dispersion generated during use of the laser scalpel in the prior art, intraoperative vision being disturbed by smoke, and a large amount of heat that cannot be cooled in time
