Abstract
Description
Technical Field
[0001] The present application relates to a controllable ultra-thin endoscope, and in particular to a control device for the controllable ultra-thin endoscope. Background Art
[0002] Currently, there are several main types of endoscopic products for gastrointestinal examinations on the market. Traditional electronic endoscopes are painful for patients to examine due to their thick bodies. Mechanical operation is complex, and the mechanical structure is easily damaged. The cost is high, and repeated use carries the risk of cross-infection. Although magnetically controlled capsule endoscopes are easy to swallow, they have low image resolution and frame rate due to battery power limitations. The time they stay in the stomach is uncontrollable, making it impossible to fully examine the esophagus. The examination is not accurate enough, and there is a risk of capsule retention. The controllable ultra-thin endoscope combines the advantages of traditional endoscopes and capsule endoscopes. It takes the form of a capsule, which is supplied with power from the outside via a wire. Its movement within the human body is guided by a magnetic control device that generates an external magnetic field.
[0003] Existing magnetic control devices generally adopt a robotic approach, requiring a rotating mechanism including X, Y, and Z guide rails and magnets, all driven by motors. This structural approach prevents the magnet from being completely close to the human body for inspection, resulting in the need for a larger magnet to achieve the desired control effect. In addition, the operator controls the movement of the magnet by operating the motor through a control panel. This indirect control of the magnet is not only prone to motion errors, but also has a delayed response and poor real-time performance. In addition, this control is not intuitive for the operator, so precise control requires repeated training. In addition, the cable of the controllable ultra-fine endoscope is long, requiring a dedicated person to hold it in hand during operation, and it is very easy to come into contact with the surrounding environment and be contaminated. Summary of the Invention

[0038] The main features of the control device for controllable ultra-thin endoscope of the present application are two mechanical arms: a magnet control arm 4 and a cable control arm 5, which are respectively mounted on the frame 1 and can be as follows: Figure 1 The components are shown as being located on different sides of the rack 1; they can also be installed on the same side of the rack 1 depending on the situation.
[0039] The main function of the magnet control arm 4 is to provide the magnet unit 6 with a degree of freedom of movement, so as to facilitate the operator to hold the magnet control arm 4 and operate the magnet unit 6 to move along a desired path.
[0040] The magnet control arm 4 is preferably formed into a foldable and hovering mechanical arm. The folding is achieved by dividing the entire magnet control arm 4 into multiple sections. The hovering main channel connecting the sections of the pivot or joint has a certain damping to achieve.
[0041] Figure 2 This is one embodiment of the magnet control arm 4. The control device for a controllable ultra-thin endoscope of the present application is not limited to this embodiment, and other embodiments are also possible.
[0042] The magnet control arm 4 includes a horizontal arm and a vertical arm 44 that are rotatably connected together.

The front end of the third connecting member 46 forms a seventh pivot 4d. The axis of the seventh pivot 4d is perpendicular to the axes of the fifth and sixth pivots 4b, 4c. Similarly, the fifth, sixth, and seventh pivots can be locked or have a certain degree of damping.
[0049] The magnet unit 6 is used to provide an external magnetic field to guide the steerable ultra-thin endoscope 9 along a desired path. The magnet unit 6 includes a U-shaped frame 61; a magnet body 64 is rotatably mounted within the U-shaped frame 61 via a magnet pivot 63. The magnet body 64 can be disc-shaped or spherical.
[0050] The magnet unit 6 is rotatably mounted on the front end of the magnet control arm 4 ; the magnet unit 6 is mounted on the seventh pivot 4 d via a connection portion 62 . Thus, the magnet body 64 can rotate about the seventh pivot 4 d and the magnet pivot 63 ; preferably, the seventh pivot 4 d and the magnet pivot 63 are perpendicular to each other.
