Embodiment Construction

[0034] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be understood that the specific embodiments described here are only used to explain the present invention, and do not limit the protection scope of the present invention.

[0035] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of illustration only and are not intended to represent the only embodiments.

[0036] Unless otherwis...

Abstract

The invention discloses a bending mechanism, a bending control device and an endoscope. A first regulation rope and a second regulation rope are arranged on a mounting surface in a winding manner along a bending groove from two opposite sides of a rotating wheel, and then the first regulation rope and the second regulation rope are fixed on the mounting surface. Therefore, in the scheme, a structure of the bending mechanism is reasonably designed, a mounting manner of the regulation ropes on the rotating wheel is simplified, and the first regulation rope and the second regulation rope are quickly mounted on the rotating wheel, so that the assembly efficiency of the endoscope is greatly improved, and further the endoscope is convenient to use by medical personnel. Two ends of the bending groove both pierce through the mounting surface, namely, the two ends of the bending groove both extend to the mounting surface, so that the situation that when being in transition to the mounting surface from a bending surface, the first regulation rope and the second regulation rope are both located in the bending groove can be guaranteed, and the situation that the first regulation rope and the second regulation rope are jacked up at a junction place of the bending surface and the mounting surface to be easily disengaged from the bending groove is avoided.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a bending mechanism, a bending control device and an endoscope. Background technique [0002] In order to clearly and intuitively understand the lesion site and improve the accuracy of lesion diagnosis, endoscope plays a vital role in the operation process. The traditional endoscope mainly includes an insertion part, a connection part and an operation part, and the insertion part is introduced into the pre-examination organ; then the operation part controls the insertion part to bend, so as to observe the organ. However, the installation method of the wire on the traditional operating part on the runner is relatively complicated, which leads to greater difficulty in assembly and seriously affects the use of the endoscope. At the same time, during the bending operation, the wire is easily detached from the rotating wheel, so that the insertion part cannot be bent, the...
