Capsule endoscope

Abstract

The invention discloses a capsule endoscope. PCB stratified structures are located in a closed inner cavity defined by a shell and an optical front cover, magnets and batteries are arranged in internal spaces formed by the PCB stratified structures, avoiding planes are arranged on the circumferential surfaces of the magnets, containing spaces are formed between the avoiding planes and the inner wall of the shell, and the sections, corresponding to the side edges of the magnets, of FPC flexible flat cables are located in the containing spaces. Multiple convex ribs are arranged at the same height of the inner wall of the shell in the circumferential direction, a layer of PCBs on the lowest portion are supported by the convex ribs jointly, and one layer of PCBs on the upper portion are pressed by a step surface on the inner wall of the optical front cover. The avoiding planes are arranged on the surfaces of the magnets, the FPC flexible flat cables are prevented from being extruded by theinner wall of the shell, the FPC flexible flat cables are effectively prevented from cracking or being fractured, and the use performance and the service life of the capsule endoscope are guaranteed.The PCB stratified structure achieves positioning through the cooperation of the convex ribs and the step surface, the structure is simpler, and the reliability is high.

Description

technical field [0001] The invention belongs to the technical field of medical instruments, and in particular relates to a capsule endoscope. Background technique [0002] Capsule endoscopy, English name: capsule endoscopy, also known as capsule endoscopy, is a capsule-shaped endoscope, which is a medical instrument used to examine the human intestine. Capsule endoscopes can enter the human body and are used to spy on the health status of the human stomach and esophagus to help doctors diagnose patients. After the patient swallows the capsule endoscope, the micro-camera encapsulated in the corrosion-resistant capsule will take pictures of the inner wall of the gastrointestinal tract, and the images will be sent to the receiving end outside the body by wireless and stored in the SD card. [0003] The shell 1 of the capsule endoscope is provided with PCB board 2, FPC flexible cable 3, magnet 4, battery 5, camera and other components, such as figure 1 , Figure 7-Figure 11 A...

AI Technical Summary

Problems solved by technology

from Figure 7-Figure 11 It can be further seen that there is a bend A in the first direction after the FPC flexible cable 3 is folded, and there is a bend B in the second direction along the circumferential surface of the magnet 4 after assembly. Since the FPC flexible cable 3 is circumscribed after the magnet 4 Bending along the direction of holding the magnet tightly can easily cause the FPC flexible cable 3 to crack or break, thus causing the capsule endoscope to fail to work normally; It is solved by increasing the capsule shell 1, but the maximum outer diameter of the capsule will be very large, which cannot meet the expected requirements

Therefore, the prior art cannot achieve both the minimization of the outer diameter of the capsule and the maximization of the magnet

[0004] In addition, the positioning method of the PCB board in the shell is generally tightened by a separately manufactured bracket. On the one hand, the bracket structure is more complicated, and a separate mold needs to be opened, which leads to an increase in cost; Will greatly affect the assembly efficiency
