Laser system for surgical department

Abstract

The invention discloses a laser system for the surgical department. The laser system comprises a laser device system, a measuring device, a control device, a deflection device and a focusing optical device. The laser device system comprises a laser wavelength conversion device composed of a near-infrared pulse laser device and a nonlinear crystal, the input end of the laser wavelength conversion device receives near-infrared pulse laser sent by the near-infrared pulse laser device and converts the wavelength of the near-infrared pulse laser, and the laser wavelength conversion device outputs infrared pulse laser and quintuple frequency ultraviolet pulse laser obtained through wavelength conversion. The measuring device comprises an optical coherence tomography system, one or more measurers and a coupler. The laser system for the surgical department is high in integration degree, good in stability, safe and reliable and effectively improves the safety of the surgical operation.

Description

technical field [0001] The invention belongs to the field of medical ultrashort pulse lasers, in particular to a surgical laser system. Background technique [0002] In recent years, with the development of laser technology and due to its special advantages, more and more lasers are used in medical surgery. For example: currently common laser corneal surgery; laser treatment of flat warts and other skin diseases; laser knife and so on. The use of lasers in surgery is scientifically validated and widely accepted for their safety and efficacy. [0003] The laser cutting method that generally adopts at present is to first cut a part to be treated with a kind of mechanical knife, after this part is incised, then use ArF excimer laser to cut the internal tissue of the part to be treated. However, the penetration of ultraviolet laser on some endothelial and matrix tissues is very small, so it is only suitable for surface cutting, and the model is large, the energy stability is p...

AI Technical Summary

Problems solved by technology

Reference imaging methods are highly subjective and difficult to perform for different sizes and contours of the site to be treated

The desired fixed position cannot be obtained with high accuracy and repeatability using this method

The method based on triangulation will make the patient feel uncomfortable, it is not friendly, and the additional complexity of this method is high

The maximum signal method is also not very reliable due to other factors (such as ambient light) that affect the quality and signal of the obtained image

[0008] To sum up, in the prior art, the surgical laser system aimed at delicate parts has defects such as complex operation, low integration, and inaccurate positioning. The existence of these defects directly affects medical safety.
