Protection device for human body pipe wall

Abstract

The invention relates to the technical field of laser endoscopes, and particularly discloses a protection device for a human body pipe wall. The human body pipe wall protection device comprises a protection assembly. The protection assembly comprises a first pipe and a second pipe, the second pipe is fixedly arranged on the inner wall of the first pipe, an optical fiber is arranged in the second pipe and can conduct laser to cut a to-be-cut piece, the length of the first pipe is larger than that of the second pipe, an opening is formed in the side wall of the first pipe, and cleaning liquid can flow in the first pipe and the second pipe and flow out of the opening, so that the cut piece to be cut is washed away. The operation precision of optical fibers is high, and the pipe wall in the human body can be prevented from being accidentally injured. The cleaning liquid flows in from the second pipe and flows out from the first pipe, and the to-be-cut piece comprises plaques or stones, so that the cut plaques or stones can be washed away by the cleaning liquid and are not easy to gather and block in a pipeline of a human body, and medical negligence is prevented. Besides, the flowing cleaning liquid can keep the device clean, so that time and labor are saved.

Description

technical field [0001] The invention relates to the technical field of laser endoscopes, in particular to a protection device for human tube walls. Background technique [0002] Endoscope is a testing instrument that integrates traditional optics, ergonomics, precision machinery, modern electronics, mathematics, and software. With image sensor, optical lens, light source lighting, mechanical device and other components, it can enter the stomach through the oral cavity or enter the body through other natural channels in the human body. Endoscopes can be used to see lesions that cannot be seen by X-rays, so they have a great effect on the medical field. At present, in the medical field, the endoscopic diagnostic technology using the endoscopic system is widely used in the minimally invasive surgery of the human body pipeline. More accurate, more intuitive and convenient. Pipelines in the human body, especially for blood vessels and ureters for clinical inspection and interv...
