Problems solved by technology

At present, capsule endoscopes developed by many institutions mainly rely on the peristalsis and contraction of organs to complete the movement along the digestive tract in the human body. The movement speed is very slow, the detection efficiency is low, and there are blind spots.

Embodiment Construction

[0025] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0026] Such as figure 2 As shown, the capsule 200 is more or less flipped along the motion track (shown by arrow v). The external magnet 201 rotates and moves laterally along the trajectory v, and the resulting magnetic force is applied between the external magnet and the dipole of the capsule, causing the supporting point 202 to roll alternately with the supporting point at the other end of the capsule 200 moving along the trajectory v . Here we see that the outer magnet is spinning in a direction consistent with its lateral motion. It was found that in order to achieve the best forward motion, the relationship between the speed of motion v and the speed of rota...

Abstract

The invention provides a method for controlling capsule or probe movement. The method comprises the following steps that 1, a capsule or a probe is placed into a sealed region; 2, an external rotating magnetic field is adopted, and the rotating force is exerted onto the capsule or the probe along a variable axis; and 3, the capsule or the probe is controlled to move in any direction of the variable axis by moving the external magnetic field. The method for controlling the capsule or probe movement provided by the invention can be used for controlling the position of the capsule or the probe in the sealed region in real time, the required magnetic field is low, and the equipment is simple.

Description

technical field [0001] The invention relates to the field of capsule endoscopy, in particular to a method for controlling the movement of a capsule or a probe. Background technique [0002] The strength of the function of the digestive tract is directly related to the absorption and utilization of the required nutrients by the human body, and is related to human health. With the acceleration of people's pace of life and changes in diet structure, the incidence of intestinal and gastric diseases is increasing day by day. Gastrointestinal diseases have become one of the most common and most frequent diseases. Gastric cancer is one of the most common malignant tumors in the world. About 640,000 people die from gastric cancer every year. According to the second cause of cancer death; The incidence rate is increasing at a rate of 2% per year, and nearly 500,000 people die from bowel cancer every year, while the growth rate of the incidence of bowel cancer in my country is twice t...
