An endoscopic device is proposed. The endoscopic device has a control guiding wire or guiding sleeve and a shape memory hollow catheter to adjust angle of rotation for a front end of the endoscopic device up to 180�, and the hollow catheter can be rotated by an angle up to 360�, such that cavities of the human body can be checked thoroughly. As the endoscopic device is fabricated at a low cost, it can be discarded after use without an infection concern that arises as a result of improper sterilization. |
