Problems solved by technology

[0003] The present invention is aimed at the problem that current endoscopes cannot effectively find deep-seated potential lesion information, and proposes an active infrared wireless capsule endoscope system, which drives wireless capsules through magnetic field suspension to perform infrared photography of the internal digestive tract. Controllable, free to move, precise positioning, and real-time observation, etc., greatly improving the efficiency of diagnosis

Embodiment Construction

[0017] Such as figure 1 The schematic diagram of the body structure of the wireless capsule is shown, the transparent glass cover 1 enables the capsule 10 to illuminate the inner wall of the digestive tract, and at the same time can take pictures normally, while preventing foreign objects from damaging the image sensor of the capsule. 2 is low power consumption, high brightness, small size SMD package LED, such as figure 2 As shown in the left view, LEDs are symmetrically and evenly distributed around the image sensor 4 . 4 is a low power consumption, small size, high performance CMOS device, and its close front is a well-designed lens group 3, including 2 groups of lens groups. The focal length of the front lens group is negative, and the focal length of the lens group close to 4 is positive. A diaphragm is set in the middle of the negative lens group, and the curved surfaces of the lenses are all aspheric surfaces. Through the design of the curved surface of the lens and t...

Abstract

The invention relates to an active infrared wireless capsule endoscopy system. A wireless capsule main body is positioned in a human body; a magnetic driver is positioned outside the human body; the wireless capsule main body is controlled by the magnetic driver to move in vivo; a detector and a signal receiver receive a signal from the wireless capsule main body and then send the signal to an information processing control centre to process the signal; the information processing control centre outputs the signal to a wireless energy emitter which emits energy; the wireless capsule main body receives the energy; and the information processing control centre outputs to a display to display parameters and a virtually reconstructed three-dimensional image. The system can photograph an inner alimentary canal to obtain infrared image information, and a capsule endoscope is controllable, so gastrointestinal endoscopy is controllable; medical workers are provided with a basis for instant, repeated and extensive detection of suspicious focuses at the same time; and the system can photograph the inner alimentary canal to obtain the infrared image information and therefore obtains accurate position information and supplies correct information for subsequent surgeries.

Description

technical field [0001] The invention relates to a medical device, in particular to an active infrared wireless capsule endoscope system. Background technique [0002] The application of wireless capsule endoscopy in the digestive tract has realized the concept of painless and non-invasive diagnosis. Currently, the use of capsule endoscopy as a clinical diagnostic method for the digestive tract is gradually becoming popular in my country. However, the wireless capsule endoscopes sold in the market are all passive Working mode, that is, the capsule body cannot move independently, and needs to rely on intestinal peristalsis to move, and furthermore, affected by the working battery, the capsule is selectively turned on and working in the digestive tract, that is, after the capsule is swallowed by the patient, the outside world cannot actively control it. It can passively receive image information from the body, which makes capsule endoscopy have a certain risk of missed detection,...
