Problems solved by technology

[0003] After the capsule gastroscope enters the body, it is necessary to image the intestines and stomach of the human body. Because the capsule gastroscope is in a free state and floats freely in the body fluid, because its position is uncertain, the images taken are too random, and it is sometimes difficult for people to judge where the gastroscope is. The orientation of the image, it is difficult to determine the overall situation in the stomach, or where the tumor is located

Embodiment Construction

[0028] The invention provides an image acquisition method of a capsule gastroscope, which utilizes an alternately controlled electromagnetic field to drive the movement track of the capsule gastroscope in a human stomach, so as to achieve the purpose of taking a full view of the stomach wall.

[0029] Described a kind of capsule gastroscope image collection method comprises the following steps:

[0030] (1) Electromagnetic coils are arranged at different positions around the capsule gastroscope;

[0031] (2) Intermittently control the energization or disconnection of the electromagnetic coils in different orientations, and the energization time between the electromagnetic coils in different orientations is separated from each other;

[0032] (3) In the power-on state, the capsule gastroscope is attracted by the magnetic field in the stomach in the body and is close to the stomach wall at the corresponding position. In the power-off state, the capsule gastroscope floats in the ...

Abstract

The invention provides an image acquisition method of a capsule gastroscope. The image acquisition method comprises the following steps: (1) arranging solenoid coils in different directions of the periphery of the capsule gastroscope; (2), discontinuously controlling the power on / off of the solenoid coils in the different directions, and mutually spacing the power-on time of the solenoid coils in the different directions; and (3), under the power-on condition, attracting the capsule gastroscope by magnetic field force in a stomach to the stomach wall in the corresponding direction, and under the power-off condition, floating the capsule gastroscope in the opposite direction to shoot images in the special direction in the stomach wall in all directions. Through the adoption of the image acquisition method, the capsule gastroscope is driven to move in the stomach through the electromagnetic field alternatively controlled to achieve the purpose of shooting the full view of the stomach wall.

Description

technical field [0001] The invention relates to a capsule gastroscope, in particular to an image acquisition method of a capsule gastroscope with a magnetic conduction module in the stomach. Background technique [0002] Capsule endoscope is a new scientific and technological product of medical development. It is widely used in the clinical diagnosis of various medical diseases. It adopts painless and non-invasive monitoring and diagnosis. After oral administration, it enters the human stomach or intestinal tract, and passes through its lens components. Close-up photographs of the internal stomach or intestinal wall conditions for clinical diagnosis and relief of patients' clinical pain. [0003] After the capsule gastroscope enters the body, it is necessary to image the gastrointestinal tract of the human body. Because the capsule gastroscope is in a free state and floats freely in the body fluid, because its position is uncertain, the images taken are too random, and it is...
