The invention discloses a rotary bending control mechanism for an endoscope. The rotary bending control mechanism comprises a cross-shaped traction plate, and a traction ball is formed at the center of the cross-shaped traction plate and fixedly connected with a fixed end of a rocker. Four tail ends of the cross-shaped traction plate are connected with traction ends of traction steel wire ropes respectively, and a control end of each traction steel wire rope is connected with a front-end bending part of the endoscope. The traction ball is movably arranged in a traction ball seat and in spherical fit with the same. By control of an operating end of the rocker, the traction ball is enabled to rotate and swing relative to the traction ball seat, and the cross-shaped traction plate pulls the four traction steel wire ropes connected with the cross-shaped traction plate to bend the front-end bending part of the endoscope. By single-hand operation, the rotating direction and bending angle of the front-end bending part of the endoscope can be controlled arbitrarily in a 360-degree range. Compared with both-hands operation, the rotary bending control mechanism has advantages of convenience in control and quickness in positioning; compared with single-hand electric operation, the rotary bending control mechanism has advantages of reliability in operation and easiness in target searching.
Description
technical field [0001] The invention relates to an endoscope component, in particular to a rotation and bending control mechanism of the endoscope. Background technique [0002] At present, in the field of medical or industrial endoscopes, to achieve bending in four directions, two methods are generally used: drum wire rope traction and sprocket chain traction. If you want to achieve manual 360° rotation and bending, you must operate with both hands at the same time, and you need a more skilled feel to achieve it. However, electric operation needs to be equipped with two geared motors and specially developed software, which has a complex structure and high cost. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a rotation and bending control mechanism of an endoscope, which can realize 360° rotation and bending with only one hand operation. [0004] In order to solve the above-mentioned technical problems, the te...
