Full view acquisition system in biological cavity

Abstract

The invention discloses a full-angle acquisition system in a biological body cavity, which belongs to the field of in-vivo inspection of medical patients. The system includes: a wireless digital camera device for image acquisition and processing in the living body, the outside of the wireless digital camera device is sealed by a fully transparent casing, the casing is made of biocompatible materials and It has a spherical shape; the inner core part of the wireless digital camera device is wrapped by a flexible PCB board to form a separate geometric body, and a plurality of cameras are evenly placed on the outer surface of the geometric body, and the whole process is carried out through the plurality of cameras. Perspective image acquisition. In the present invention, a plurality of cameras are evenly placed on the outer surface of the inner core part of the wireless digital camera device, so that image data can be collected from all angles of view, and the shape is spherical, which is easy to enter into the biological cavity.

Description

technical field [0001] The present invention relates to the field of in-vivo examination of medical patients, and in particular relates to the image acquisition of full-view in vivo, static zero-power consumption technology of camera device, data transmission and processing and other technologies. Background technique [0002] In order to non-invasively examine the body cavity organs in animals or humans, especially the digestive tract body cavity; a wireless endoscopic capsule diagnostic system is currently used. Among them, the wireless capsule part is swallowed by the subject from the mouth, and traverses the gastrointestinal organs such as the gastrointestinal tract through the gastrointestinal peristalsis in the body, and at the same time collects relevant data in the digestive tract to complete the entire diagnostic process. [0003] Existing known wireless capsules place a miniature camera and LED light source at one or both ends of the wireless capsule for its illumi...

Problems solved by technology

Although they have adopted different methods of expanding their field of view (including methods such as mechanical rotation); but these inventions cannot achieve full-view image acquisition; in addition, mechanical methods are expensive in terms of power consumption and implementation complexity, and will also Increase the size of the capsule in the body cavity

[0005] In addition, there is a common problem of static power consumption in the existing endoscope system, that is, the system is still in the state of normal power consumption or micro power consumption in the non-working state. For this reason, the patent numbers are CN01807801. In the technologies provided by inventions such as CN200510020338.4, a control switch (such as a steel reed pipe) is adopted, but this switch requires each capsule to carry a magnetically strong enough magnet, which increases the overall volume of the capsule; and shock resistance and reliability Poor, it will cause a large amount of power loss during transportation and storage, which directly affects the use time and actual effect of the capsule in the body
