Problems solved by technology
[0003] At present, due to the limitation of structural space, some conventional electronic endoscopes have no zoom function, and some have poor precision control during the focus adjustment process, which cannot ensure the accuracy of focus adjustment and positioning accuracy.
[0004] Therefore, the prior art lacks a device and structure for realizing efficient and precise zoom adjustment of the above-mentioned electronic endoscope

Embodiment Construction
[0029] The present invention will be further described below in conjunction with the accompanying drawings and specific implementations.
[0030] like figure 1 As shown, the zoom adjustment mechanism is divided into two main components, namely, the zoom adjustment mechanism 1 of the operation part and the zoom mechanism 2 of the insertion part, and the two mechanisms are connected by a wire drawing 20 . The wire drawing and wire drawing tube are arranged inside the insertion tube, and the zoom adjustment mechanism of the operation part and the zoom mechanism of the insertion part are respectively arranged at both ends of the insertion tube, and are fixedly connected with the insertion tube to ensure that the wire is in a tensioned state during any process.
[0031] The zoom adjustment mechanism 1 of the operation part is mainly a set of crank-slider mechanism.
[0032] like figure 2 , image 3 and Image 6 As shown, the zoom adjustment mechanism 1 includes a crank mechani...

The invention discloses a zoom adjusting mechanism of an electronic endoscope. Comprising a crank mechanism, a connecting rod sliding block mechanism, a sliding groove mechanism and a bottom plate assembly. The crank mechanism and the sliding groove mechanism are fixedly arranged on the bottom plate assembly, after the connecting rod end of the connecting rod sliding block mechanism is rotationally connected with the crank mechanism, the sliding block end of the connecting rod sliding block mechanism is arranged in the sliding groove mechanism and slides in the sliding groove mechanism, and the sliding block end of the connecting rod sliding block mechanism is connected with the insertion part zooming mechanism through a drawing wire. According to the mechanism, flexible, continuous and efficient zoom adjustment of the endoscope can be achieved, the mechanism can be suitable for manual and automatic zoom adjustment of the endoscope, meanwhile, the mechanism is easy and convenient to operate and low in cost, and the use cost of the endoscope can be effectively reduced.
Description
technical field [0001] The invention relates to a small endoscope adjustment structure in the technical field of medical operation detection devices, in particular to an electronic endoscope zoom adjustment mechanism. Background technique [0002] As a common auxiliary diagnostic equipment in modern medical care, endoscope is often used in the early diagnosis and surgical treatment of diseases of gastrointestinal and other organs in the body. In the process of diagnosis, in order to improve the efficiency of diagnosis, it is first necessary to observe the whole situation with a large field of view (wide-angle), and after finding the suspicious area, it is necessary to precisely locate the position of the lesion with high resolution. This requires adjustment of the focal length of the endoscope. [0003] Due to the limitation of structure space, some of the conventional electronic endoscopes have no zoom function, and some have poor precision control during the focal length ...
