The invention provides an endoscope system and a method for detecting the contact between the end of the endoscope and the tissue. By controlling the video stream gain and exposure time, the current brightness of the video stream is within the target brightness range, and the endoscope is realized. Measure the distance between the terminal end and the tissue, and when the distance between the endoscope end and the target tissue is less than a preset distance, a contact warning is issued and a contact judgment is triggered. The texture feature information of the target tissue before and after the output light power is increased is compared to determine whether the end of the endoscope is in contact with the target tissue. The endoscope system provided by the present invention judges whether the tip of the endoscope is in contact with the target tissue by comparing the change of the texture feature information of the target tissue before and after the output light power increases, which improves the accuracy of the contact prompt and effectively avoids the The damage caused to the tissue during the detection of the target tissue by the endoscope.
Description
technical field [0001] The invention relates to the field of medical instruments, in particular to an endoscope system and a method for detecting the contact between the end of the endoscope and tissue. Background technique [0002] With the continuous development of medical technology, endoscopes, as a detection instrument that integrates traditional optics, ergonomics, precision machinery, modern electronics, mathematics, and software, have become more and more widely used. The endoscope can enter the body of the subject to be detected (such as the esophagus) to obtain images of the part to be detected, and then determine whether there is a lesion in the part to be detected. The endoscope can be used to see lesions that cannot be seen on X-rays, so it is very useful for doctors. For example, with the help of an endoscope, doctors can observe ulcers or tumors in the stomach and formulate the best treatment plan accordingly. [0003] When using an endoscope for inspection,...
