Embodiment Construction

[0010] The present invention will be further described below in conjunction with the accompanying drawings.

[0011] As shown in Figure 1, the present invention includes a mirror body tube 5, an endoscope lens 1 and a mirror neck 2 are arranged at the front end of the mirror body tube 5, and an operating part 8 is provided at the rear end of the mirror body tube 5, and the mirror body Between the tube 5 and the lens 1, there are at least two sets of snake components, that is, the distal snake component 3 and the proximal snake component 4; on the operating part 8, there are at least one set of angles corresponding to the snake components. Screw button 7, multiple groups of angle screw buttons 7 are correspondingly connected with the angle sprocket 6 through the rotating shaft, and a section of angle chain 9 is arranged on the angle sprocket 6 to mesh with it, and the two ends of the angle chain 9 are connected with the angle control rope 10, and the angle control rope Both end...

Abstract

The invention discloses a multi-bend part and a control device of an endoscope, including an endoscope barrel, an endoscope lens and an endoscope neck which are arranged on the front end of the endoscope barrel, and an operation part which is arranged on the back end of the endoscope barrel. At least two groups of snake bone components of a front end snake bone component and a near end snake bone component are arranged between the endoscope barrel and the lens. At least one multi-group angle spiral button is arranged on the operation part, which is corresponding to the snake bone components. The multi-group angle spiral button is corresponding to and connected with an angle sprocket through a shaft. A section of angle chain is arranged on the angle sprocket in a way of meshing. The two ends of the angle chain are connected with an angle control rope. The two ends of the angle control rope are respectively and fixedly connected with the front ends of the front end snake bone component and the near end snake bone component. The invention is mainly applicable to medical and industrial endoscopes, which results in that the bending angle of the bending part of the endoscope is greatly increased, the operation is more flexible and convenient, the check blind spot is reduced to zero and the accuracy for the diagnosis and the endoscopic therapy is greatly improved.

Description

technical field [0001] The invention relates to a bending part of an endoscope and its control technology, in particular to a multi-bending part of an endoscope and a control device. Background technique [0002] The bending part of the traditional endoscope is a single bending part device, which is coaxial and bends in four directions. The bending angle: gastroscope is the largest, 210 degrees up, 90 degrees down, 100 degrees left and right; colonoscope 180 degrees up and down, 160 degrees left and right. In view of the above-mentioned bending function of the device, during gastroscopy and colonoscopy, most of the lesions can only be observed from the side, and the lesions cannot be observed in multiple directions, so it is easy to cause misdiagnosis and missed diagnosis. The single bending part of the industrial endoscope also has the disadvantage of not being able to perform detailed inspections of the observed object from different directions and angles due to the short...
