Description

Technical Field

[0001] The utility model relates to an integrated built-in mounting bracket for a capsule endoscope and a dual-lens capsule endoscope comprising the same, belonging to the technical field of capsule endoscopes. Background Art

[0002] Capsule endoscopes are increasingly widely used in the examination of patients' digestive tract diseases. The examinee takes the capsule endoscope orally, and with the help of gastrointestinal peristalsis, it moves in the digestive tract and takes images. Doctors use an external image recorder and an imaging workstation to understand the entire digestive tract condition of the examinee, so as to make a diagnosis of their condition. Capsule endoscopes have the advantages of convenient examination, non-invasive, wire-free, painless, no cross-infection, and do not affect the normal work of patients, etc. They expand the field of vision of digestive tract examinations, overcome the deficiencies of traditional insertion endoscopes such as poor tolerance and inapplicability to the elderly, weak, and critically ill patients, and can be used as the preferred method for the diagnosis of digestive tract diseases, especially small intestine diseases.

[0003] Capsule endoscopes usually include devices such as a capsule shell, a camera module, a battery, an antenna, and a PCB board. The battery is arranged between two PCB boards through a spring to provide power for the PCB board, etc. Due to spring failure or insufficient preset elastic force, the power supply to the PCB board may be poor. In practice, due to transportation, vibration, etc., the relative displacement of each component may occur, which will affect the use. To overcome this problem, some manufacturers will use adhesives during assembly, which makes the assembly process complex and reduces the production efficiency.

[0004] The antenna mainly plays the role of receiving and transmitting signals. For most capsule endoscopes, the antenna is assembled on the circuit board and then assembled into the capsule shell. Since the bearing of the antenna mainly relies on the circuit board, during assembly or use, the antenna is prone to deformation problems, resulting in problems with signal reception and transmission. Content of the Utility Model

[0005] The utility model provides an integrated built-in mounting bracket for a capsule endoscope and a dual-lens capsule endoscope comprising the same, which can effectively limit the devices such as the camera module, battery, antenna, and PCB board in the capsule shell, ensure the stability of each component during transportation, use, etc., avoid problems such as spring failure or insufficient preset elastic force, ensure the power supply stability, and at the same time improve the stability of antenna assembly, making it easier to assemble the battery, antenna, PCB board, etc. into the capsule shell, facilitating assembly and improving the assembly efficiency.
