technical field

The utility model relates to the field of medical endoscopes, in particular to a rotatable endoscope with variable viewing angle.

Background technique

An endoscope is a testing instrument that integrates traditional optics, ergonomics, precision machinery, modern electronics, mathematics, and software. One has an image sensor, optical lens, light source lighting, mechanical devices, etc., it can enter the stomach through the mouth or enter the body through other natural orifices, and the endoscope can see the lesions that cannot be displayed by X-rays, so it is very useful for doctors Physicians can use endoscopes to more accurately grasp the condition and formulate better treatment plans for patients.

At present, most endoscopes are bent at a small angle on the rigid tube to observe the surrounding tissue. Although this observation has certain advantages, the rotation angle is insufficient, and the observation field is insufficient, and it is still impossible to more accurately grasp the patient's internal situation. Part of the tube endoscope is used, and the front end of the tube is provided with a mechanism to bend the tube, such as the bending end in Chinese patent CN204318701U. The length of the bending end is long and the bending angle is too large, which is easy to bring discomfort to the patient. and more likely to cause bleeding.

Therefore, we designed a variable viewing angle rotatable endoscope to solve the above problems.
