Using an endoscope, lesions that cannot be shown by X-rays can be seen, so it has great significance in the medical field. Currently, in the medical field, the diagnostic technology of endoscopes using an endoscope system is widely used in minimally invasive surgery of human internal ducts. It is mainly used to treat the diseased parts of patients, which can reach the lesion directly, making the detection examination or surgical operation more accurate, more intuitive and convenient. In the internal ducts of the human body, especially for clinical examinations and interventional surgeries of blood vessels and ureters, under the detectable and visible environment of an electronic endoscope, the end of the endoscope can be inserted into the human body, and laser technology is used to remove or ablate stones or plaques on the walls of blood vessels and ureters in the human body. Currently, in such surgeries, the operation is carried out by manually controlling the optical fiber according to the doctor's experience. When in use, the operation of the optical fiber is not precise enough, which may accidentally damage the tube walls in the human body. Moreover, the cut plaques are also prone to aggregation and blockage in blood vessels or ureters, which may lead to medical accidents. Therefore, there is an urgent need for a protection device for human body tube walls to solve the above problems. Summary of the Invention

In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0027] The present invention provides a protection device for the human body tube wall, such as Figure 1 shown. When in use, the operation precision of the optical fiber 121 is high, which can prevent accidental injury to the tube wall in the human body. Moreover, the cut plaques and calculi are not easy to aggregate and block in the human body ducts, avoiding medical accidents. The operation is simple and convenient to use.

[0028] Such as Figure 1 and Figure 2 shown. Specifically, a protection device for the human body tube wall includes a protection component 1. The protection component 1 includes a first tube 11 and a second tube 12. The second tube 12 is fixedly arranged on the inner wall of the first tube 11. An optical fiber 121 is arranged in the second tube 12. The optical fiber 121 can conduct laser to cut a workpiece to be cut 2. The length of the first tube 11 is greater than that of the second tube 12, and an opening is provided on the side wall of the first tube 11, which can enable the cleaning liquid to flow in the first tube 11 and the second tube 12 and flow out from the opening to wash away the workpiece to be cut 2 after cutting. When in use, the operation precision of the optical fiber 121 is high, which can prevent accidental injury to the tube wall in the human body. In this embodiment, the cleaning liquid flows into the second tube 12 and flows out from the opening of the first tube 11. The workpiece to be cut 2 includes plaques or calculi, so that the cut plaques or calculi can be washed away by the cleaning liquid, avoiding the aggregation and blockage of the cut plaques or calculi in blood vessels or ureters and preventing medical accidents. Moreover, the flowing cleaning liquid can keep this protection device for the human body tube wall in a clean state. After use, only disinfection is required, which saves time and effort. Especially for critically ill patients or patients with infectious diseases, the probability of cross-infection can also be reduced.

[0029] In this embodiment, the central angle of the opening corresponding to the first tube 11 is 120 - 160 degrees. It is convenient for production and manufacturing, with low cost and easy to implement.

[0030] Specifically, it further includes an imaging component 122. The imaging component 122 includes an imaging body 1221 and a light guiding part 1222. The imaging body 1221 is arranged at the detection end of the light guiding part 1222. A channel for detection is opened in the light guiding part 1222 to convert the optical signal into an electrical signal, so that the internal situation detected by the laser endoscope can be presented on the screen for easy observation. Through the imaging body 1221, the situation inside the human body tube wall can be very intuitively detected, so as to diagnose the condition in a timely and accurate manner and improve the operation precision.

[0031] Furthermore, the optical fiber 121 passes through the light guiding part 1222, so that the optical fiber 121 can be slid back and forth, which can make the operation precision of the optical fiber 121 high, prevent accidental injury to the blood vessel wall or ureter wall, and reduce the risk of medical accidents.

[0032] In this embodiment, the first tube 11 is made of stainless steel, which is resistant to weakly corrosive media such as air, steam, and water, and is rust-proof. This makes it readily available and low-cost. In other embodiments, the first tube 11 can be made of other materials as long as they provide rust and corrosion resistance, without limitation. The second tube 12 is made of a polymer material.

[0033] Furthermore, the protective assembly 1 further includes a flexible cover 123, which is disposed between the light guide portion 1222 and the second tube 12 to prevent the light guide portion 1222 and the second tube 12 from colliding and abrading with each other. In other embodiments, the flexible cover 123 may also be in other forms, as long as it can achieve the function of preventing the light guide portion 1222 and the second tube 12 from colliding and abrading with each other, and is not limited here.

[0034] In this embodiment, an optical fiber sleeve 1211 is provided on the outside of the optical fiber 121. The refractive index of the optical fiber sleeve 1211 is lower than that of the optical fiber 121, which can prevent the laser from scattering during the transmission process so that the light energy of the input laser can be output to the maximum extent. It can also prevent the optical fiber 121 from being worn and bent during use, thereby increasing the service life of the optical fiber 121 and reducing costs.

[0035] In this embodiment, the cleaning fluid is physiological saline at a concentration of 0.85-0.9%. This concentration of physiological saline has an osmotic pressure similar to that of human blood and a sodium content similar to that of plasma, preventing cells from rupturing due to dehydration or excessive water absorption. It also cleans wounds during use, ensuring the patient's safety.

[0036] In this embodiment, the length of the first tube 11 and the second tube 12 is 10 mm, and the wall thickness of the first tube 11 and the second tube 12 is 0.1-0.2 mm, which can reduce the wear on the patient's wound and facilitate subsequent precise operation and treatment.

[0037] In this embodiment, the outer wall of the first tube 11 is a smooth surface, which can reduce the wear on the patient's wound, facilitate operation and easy implementation.

[0038] In this embodiment, the protection component 1 further includes an outer sheath 13 sleeved outside the protection component 1 , which facilitates the operator to hold the device, and the outer sheath 13 can prevent the protection component 1 from being bumped.

[0039] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the embodiments of the present invention. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here.
