Description

Endoscope device and its application Technical field

The present invention relates to an endoscope, and more particularly to an endoscopic device for simultaneous medical examination, sampling and treatment, and more particularly, as a minimally invasive and non-invasive medical device.

Background technique

With the development of modern science and technology, the use of electronic imaging medical testing equipment in the medical field has become more and more widely used. At present, the application of the medical endoscope has been continuously developed and expanded, and the main use thereof is for medical examination and medical operation. In particular, when the medical endoscope is used for medical treatment, it has a relatively obvious superiority with respect to the conventional medical treatment. Where the medical endoscope is used for medical examination, the internal condition of the patient's body can be clearly and clearly seen. In addition, when the medical endoscope is used for medical manipulation, the wound caused by endoscopic surgery is finer than that of the wound treated with conventional surgery, compared to the conventional surgical treatment. Therefore, when an endoscope is used for medical examination or surgery, the trauma of the operation can be reduced, and the accuracy and safety of the medical treatment can be increased, so that the patient's acceptance of medical treatment is greatly increased.
