Capsule endoscopy with automatically adjusted shooting frequency and method thereof

Abstract

The invention discloses a capsule endoscopy with automatically adjusted shooting frequency and a method thereof. The capsule endoscopy comprises a capsule endoscopy shell, a battery, a camera unit, a control module, a wireless signal transceiving module, a coil, a current inductor, a frame rate control module and a magnetic field generator, wherein the coil, the current inductor and the frame rate control module are arranged in the shell; the external magnetic field generator generates a magnetic field covering an activity range of the capsule endoscopy; the current inductor are connected with two poles of the coil to form a capsule motion signal; one end of the control module is connected with the current inductor and receives the capsule motion signal, while the other end is connected with the frame rate control module to transmit a control signal for adjusting the shooting frequency; and the frame rate control module is connected with the camera unit and directly controls the shooting frequency. The shooting frequency of the capsule endoscopy is controlled through a device for automatically adjusting the shooting frequency according to the movement of the capsule endoscopy, so that the electric quantity of the capsule endoscopy is saved, the miss shooting rate is reduced and the number of repeated images is reduced.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a capsule endoscope with automatic adjustment of shooting frequency and a method thereof. Background technique [0002] In 2001, the world's first capsule endoscopy system was approved by the US FDA for clinical use. By the end of 2006, more than 300,000 people around the world had received capsule endoscopy. At present, this inspection technology has been used in more than 50 countries around the world. Because this technology has the advantages of simple operation, convenient inspection, non-invasive, painless, and no cross-infection, it also solves the problem that the small intestine was a blind area in the past. Today, capsule endoscopy It has gradually become the gold standard for assisting physicians in examining the small intestine. [0003] The emergence of capsule endoscopy technology has brought an innovative revolution to the medical clinical diagnosis of the...

However, the image volume of capsule endoscopy is huge. According to two pictures taken per second, the number of pictures produced during the 6-8 hour inspection process reaches 43,200-57,600. All these pictures are carefully interpreted by doctors to make a correct diagnosis. , the workload of film reading is huge, it takes a lot of time, it is easy to get tired and miss valuable diagnostic information, the diagnostic efficiency is extremely low, and it is difficult to cope with a large amount of inspection; Slower results in missed shots are still serious. For the small intestine examination, the average missed shots rate is 20% to 30%.

Although the current frame rate of capsule endoscopy can reach 8 frames per second or even higher, it directly affects the lifespan of capsule endoscopy, because the battery life of capsule endoscopy is limited, and high frame rate is equivalent to high consumption, which shortens the life of capsule endoscopy. Due to the long lifespan, the complete intestinal inspection cannot be completed. The low frame rate can save battery consumption, but there may be missed shots; therefore, reasonable control of the shooting frame rate is an important factor affecting capsule endoscopy.

[0004] Existing capsule endoscopes include shells, batteries, image transmitters, camera units, control modules, wireless signal transceivers, and in vitro information transceivers. Manual control of the frame rate of capsule endoscopes has been achieved, but the entire inspection time can be long It is unrealistic to have a doctor accompany you through the entire inspection process for 8 to 12 hours; and the frequency of intestinal peristalsis is 4 to 5 times per minute, and the capsule endoscope stays in place most of the time in the intestinal tract, resulting in capsule endoscopy. There are a large number of identical images in the images taken by the endoscope
