The invention discloses a tissue probe mirror, in particular to the technical field of medical devices. The tissue probe mirror not only solves the problem that the existing endoscope cannot be punctured and explored in tissue, but also solves the problem that the back end of the existing endoscope is heavy and not easy to be controlled. A light guide optical fiber is arranged in the lens barrel,and the light guiding optical fiber is arranged on the circumference close to the inn wall of the lens barrel. The light guiding optical fiber is arranged on the inner wall of the lens barrel. The variable diameter imaging optical fiber is located in a circular cavity surrounded by the light guide optical fiber. The light guide fiber extends coaxially with the variable diameter imaging fiber, thetop end of the variable diameter imaging fiber constitutes the middle part of the curved surface structure, the top end of the light guide fiber constitutes the outer edge of the curved surface structure, the rear end face of the mirror body is the image magnification display end face, the end face and the mirror body axis are at a certain angle, and the outer surface of the mirror body is provided with a scale.
Description
technical field [0001] The invention relates to the technical field of medical instruments, in particular to a tissue exploration mirror. Background technique [0002] With the advancement of medical device technology, the search mirror has become an essential medical device in the current hospital. However, the use environment of the existing probe mirror can only be used in the liquid phase and the gas phase, and cannot be used between solid-phase tissues, especially in the brain parenchyma. Secondly, the existing endoscope needs to be equipped with an optical lens at the front and rear ends during use, and a CMOS photosensitive element and a rear circuit follow-up board at the rear end to collect images and transmit them to the remote display through a cable. Image display is performed. The weight of the rear end of the endoscope is heavy, which is far greater than the weight of the front end of the endoscope. It is very inconvenient during the operation. The phenomenon...
