Problems solved by technology

[0008] The object of the present invention is to provide an electronic endoscope with a camera that can rotate outwards to solve the problem in the prior art that the diameter of the instrument channel tube can only be smaller than the diameter of the scope minus the electronic endoscope because the electronic camera and the instrument passage tube are arranged side by side in the scope. The width of the camera diameter is set, resulting in the problem that the diameter of the instrument channel tube is small and cannot pass through the larger diameter instrument

Embodiment 1

[0056] An electronic endoscope with a camera head that can be rotated outward, such as figure 1 and figure 2 , including an electronic camera 1 , an external rotation assembly, a mirror body 2 and an operating part 3 . The side of the electronic camera head 1 is movably connected with the endoscope body 2 through the external rotation assembly, the electronic camera head 1 is connected to the end of the wire belt 7, and the other end of the wire belt 7 passes through the mirror body 2 and is connected to the operation part 3. The wire belt 7 is a long shoulder-pole type, and the inside has parallel wires and draglines, and the surface is wrapped with a waterproof material. Wire belt 7 is eccentrically connected with electronic camera 1 bottom surface. The external rotation assembly includes more than one rotating shaft 82 , one end of the external rotation assembly is connected to the electronic camera 1 , the other end of the external rotation assembly is connected to the ...

Embodiment 2

[0063] The second embodiment is basically the same as the first embodiment, except that the endoscope can be bent. Mirror body 2 selects bendable material for use, and rotating shaft 82 selects bendable soft rotating shaft 82 for use, and wire belt 7 is also bendable material, and endoscope can be done passive bending in the lumen, conveniently passes through the lumen that has curved section.

Embodiment 3

[0065] The principle of embodiment three is similar to that of embodiment one, and the difference is that the rotating shaft 82 is not used to transmit the torque, but the inward rotation cable 93 and the external rotation cable 92 of the handwheel adjustment mechanism 9 are used to control the internal rotation and rotation of the electronic camera 1. External rotation, such as Image 6 and Figure 7 . The rotating shaft 82 can be at least one discontinuous short rotating shaft 82, which can reduce weight and facilitate maintenance. The structure of the hand wheel is similar to that used in existing endoscopes, and it can also be the simple structure in the schematic diagram of the present invention. The toggle lever 91 on the handwheel is fixedly connected to the wire winding member 95 in the handwheel by passing through the wheel shaft 94 of the hand wheel. The wire winding members 95 are symmetrically distributed on both sides of the wheel shaft 94 and are respectively c...

Abstract

The invention provides an electronic endoscope with an externally rotatable camera. The electronic endoscope comprises the electronic camera, a wire band, an externally rotating assembly, a mirror and an operation part; the electronic camera is movably connected with the mirror through the externally rotating assembly and connected to the end portion of the wire band, and the other end portion of the wire band penetrates through mirror and is connected with the operation part; one end of the externally rotating assembly is connected to the electronic camera or the wire band, the other end of the externally rotating assembly is connected with the operation part, and the middle of the externally rotating assembly is movably connected to the tube wall of the mirror. According to the electronic endoscope with the externally rotatable camera, a tail-end channel can be enlarged; compared with existing endoscopes, the diameter of the existing endoscopes can be maintained, and on the premise of not affecting the endoscope to successfully enter the human body, the endoscope can enlarge the tail-end channel after going through the narrow section of the channel of the human body, so that more apparatuses go through conveniently, larger foreign bodies are taken out and flushing is conducted more smoothly.

Description

technical field [0001] The invention relates to an electronic endoscope with a camera head that can rotate outward. Background technique [0002] Clinically, endoscopic surgery has been widely carried out. The early endoscope is a fiber endoscope, which conducts images through tens of thousands of closely arranged fibers. However, the glass fiber cannot be made thinner, which limits the improvement of pixels, and the glass is thinner and easier to break. Later, the fiberscope was gradually replaced by a higher-definition electronic endoscope. [0003] Currently commonly used electronic endoscopes include: electronic esophagoscope, electronic gastroscope, electronic duodenoscope, electronic enteroscope, electronic colonoscope, electronic rectoscope, electronic laryngoscope, electronic bronchoscope, electronic laparoscope, electronic choledochoscope , Electronic cystoscopy, electronic ureteroscopy, electronic nephroscopy, electronic hysteroscopy, electronic arthroscopy, elec...
