Abstract

The invention discloses a laser surgical endoscope, comprising a sealed drawtube, a field lens part, an image transferring system, a light intake part, an ocular part, a lead beam, a laser protecting lens and a window plate. The field lens part, the image transferring system, the light intake part, the ocular part, the lead beam and the laser protecting lens are arranged inside the sealed drawtube sequentially from left to right. The window plate is installed at the front end of the field lens part, and the laser protecting lens is arranged at the back end of the ocular. The lead beam is arranged inside the sealed drawtube between the window plate and the light intake part. One end of the lead beam is connected with the light intake part and the other end of the lead beam is connected with the window plate. Adopting the new design of arranging the laser protecting lens inside, the laser surgical endoscope can avoid injuries and damages to the operators and back end equipment such as a video camera and can ensure the quality of the acquired image so that the medical operators can directly carry out laser surgery under the endoscope. Therefore, the laser surgical endoscope has great practical significance for production.

Description

technical field

[0001] The invention relates to the technical field of medical instruments, in particular to a laser surgical endoscope. Background technique

[0002] Endoscope, referred to as endoscope for short, is a device used to directly observe the internal cavity of human organs. At present, the implementation of laser surgery under the endoscope has become the frontier means in the medical field due to its safety and efficacy.

[0003] Laser therapy is the use of lasers of different wavelengths to perform efficient vaporization or lithotripsy on human lesions. Since the power used in laser therapy generally exceeds Class 3B lasers (GB7247.1-2001), ordinary endoscopes do not have protective devices and are vulnerable to laser damage, so laser surgery cannot be completed at all. Currently, there is no available laser surgery available on the market. laser surgery endoscope.

[0004] In order to carry out laser surgery, the current remedial method for clinical use of...
