Problems solved by technology
Traditional endoscopes inevitably have various pipes, and these pipes will cause greater pain to patients due to insufficient flexibility
At the same time, the traditional endoscope also has the disadvantage of possible cross-infection
Although the existing capsule endoscopes solve the above-mentioned problems, there are still problems such as the long time for the capsule endoscope to be removed from the body, and the difficulty in controlling the speed and posture of the movement.

Embodiment
[0023] As shown in Fig. 1(a)-Fig. 1(b), an autonomously moving capsule endoscope includes a motion propulsion mechanism, a steering mechanism, a control circuit 6 and a battery in sequence from top to bottom. The motion propulsion mechanism is installed on the steering mechanism, the control circuit is located below the steering mechanism, the battery is used to supply power to the control circuit, and both the battery and the control circuit are located at the tail of the capsule.
[0024] The motion propulsion mechanism includes a current controllable coil 1, an arc-shaped armature 2, and an elastic shell 3. The elastic shell 3 seals the motion propulsion mechanism to form an inner cavity, and the inner cavity is filled with insulating liquid. The arc-shaped armature 2 is closely attached to the On the inner wall of the elastic shell 3, and symmetrical about the central axis of the capsule endoscope, the current controllable coil 1 is symmetrically installed on the top of the...

The invention discloses an autonomous motion type capsule endoscope and an autonomous motion method. The autonomous motion type capsule endoscope comprises a motion propelling mechanism, a steering mechanism, a control circuit and a battery, wherein the motion propelling mechanism comprises a current controllable coil, an arc-shaped armature and an elastic outer shell. The elastic outer shell seals the motion propelling mechanism to form an inner cavity, the inner cavity is filled with insulating fluid, the arc-shaped armature is attached to the inner wall of the elastic outer shell and is symmetric with the middle axis of the capsule endoscope, the current controllable coil is symmetric with the center axis of the capsule endoscope and is arranged on the top of the steering mechanism, the steering mechanism comprises at least three steering bars which are in axial symmetry, the control circuit controls the propelling speed of the capsule endoscope by changing the frequency and amplitude of currents passing through the current controllable coil, and the included angle between the center line of the propelling mechanism and the axis of the capsule endoscope is controlled by controlling the amplitude and direction of voltage applied to the steering bars. The autonomous motion type capsule endoscope is simple in structure and easy to manufacture.
Description
technical field [0001] The invention relates to the field of biomedicine, in particular to an autonomously moving capsule endoscope and an autonomously moving method. Background technique [0002] With the improvement of the quality of life, people have higher and higher requirements for medical devices, and it has become an important requirement for people to reduce the discomfort caused by the inspection equipment during the physical examination of patients as much as possible. Traditional endoscopes inevitably have various pipes, and these pipes will bring great pain to patients due to insufficient flexibility. At the same time, traditional endoscopes also have the disadvantage of possible cross-infection. Although the existing capsule endoscopes solve the above-mentioned problems, there are still problems such as the long time for the capsule endoscope to be removed from the body, and the difficulty in controlling the speed and posture of the movement. Considering the ...
