Capsule gastroscope capable of changing photographing angle

Abstract

A capsule gastroscope capable of changing the photographing angle comprises a capsule shell body (1), an LED light source (2), an automatic focusing lens (3), a microprocessor (4), a battery (5) and an antenna (6), wherein the capsule shell body (1) is cylindrical, and the two ends of the capsule shell body (1) are semispherical transparent shields. The automatic focusing lens (3) is located in the transparent shield. The periphery of the automatic focusing lens is further provided with the LED light source (2). The automatic focusing lens (3) and the LED light source (2) are connected with the microprocessor (4). The microprocessor (4) is connected with one end of the battery (5), and the other end of the battery (5) is connected with the antenna (6). The capsule gastroscope capable of changing the photographing angle is characterized in that the antenna end of the capsule shell body (1) is further provided with an eccentric wheel (7) and a power driving device (8). The capsule gastroscope capable of changing the photographing angle can increase the photographing angles of the inner wall of the stomach.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a capsule gastroscope capable of changing the photographing angle. Background technique [0002] Gastroscopy is the most commonly used method for checking diseases in gastroenterology. The existing gastroscope is mainly composed of a lens and a guide core. When performing gastroscopy for a patient, it is necessary to insert the gastroscope from the mouth, which is very painful for the patient and inconvenient to operate. [0003] In order to change this situation, someone designed a capsule gastroscope, which is installed in a corrosion-resistant capsule through measuring equipment and sensors. Take pictures and transfer the resulting pictures to your computer. For example, Chinese patent 201410141477.1 discloses a capsule endoscope system with magnetic field positioning function and its capsule endoscope. The capsule endoscope is equipped with a magnetic field measureme...

Problems solved by technology

For example, Chinese patent 201410141477.1 discloses a capsule endoscope system with magnetic field positioning function and its capsule endoscope. The capsule endoscope is equipped with a magnetic field measurement module. Measure the strength and generate a field strength signal, and then send the field strength signal through the radio frequency unit. The field strength characteristics of the magnet can be measured and positioned in advance and a field strength model is generated. Comparing the field strength signal with the magnetic field model, the capsule can be obtained. The position information of the mirror, but the magnetic field module in this technical solution will interfere with the normal operation of the capsule wire, which will cause serious feelings in the transmission of photo information, resulting in the loss of part of the photo information and the unclear situation of some photos; Chinese patent 201210441161.5 The invention is disclosed A self-suspending capsule endoscope is proposed, including a capsule housing, an LED light source, a sensor, a lens, a lens cover, and a battery. In this technical solution, the weight of half of the capsule is greater than that of the other half, so that when the capsule operates in body fluid Keep it vertical, and the lens is parallel to the running direction of the capsule, but in this technical solution, the capsule enters the stomach and floats in the gastric juice, so it can only shoot the upper and lower areas of the stomach, and cannot change the shooting area, resulting in some areas of the stomach being leaked The state of shooting; Chinese patent 201320159604.1 discloses a capsule gastroscope, which has a capsule probe and an image display device. The capsule probe transmits video signals to the smartphone through a video wire, but this technical solution does not have the ability to automatically adjust the shooting area inside the stomach. Function

[0004] It can be seen that the above-mentioned prior art has not effectively solved the problem of missing pictures of some areas in the stomach by capsule gastroscopy.
