Lens base and capsule endoscope thereof

Abstract

The invention provides a lens base. A protruding part protruding downwards is arranged at the center of the lower surface of the lens base, and a first groove used for being matched with a photosensitive chip is arranged at the center of the protruding part; at least two positioning columns are further arranged on the bottom surface of the lens base, and are used for being arranged on a first PCBon the lower surface of the lens base in a matched mode; and a protruding part protruding upwards is arranged at the center of the upper surface of the lens base, and an internal thread used for arranging a lens in a matched mode is arranged at the center of the protruding part. The invention further provides a capsule endoscope adopting the lens base. The capsule endoscope further comprises a second PCB and a third PCB which are located at the two ends of a battery, the surfaces, close to the battery, of the second PCB and the third PCB are each provided with a conductive elastic component tobe connected with a positive electrode and a negative electrode of the battery, and the outer surfaces of the second PCB, the third PCB and the battery are covered with an insulating sleeve. The lensbase and the capsule endoscope thereof have the advantages of being convenient to assemble and stable in structure, and the problems of stray light, black edges, light reflection and the like of images are effectively solved.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a capsule base and a capsule endoscope using the same. Background technique [0002] Capsule endoscopy, as a new type of digestive tract physical examination program, has developed rapidly in recent years. Capsule endoscopy has advantages that cannot be compared with traditional intubation endoscopy. It has the advantages of convenient inspection, no trauma and pain, and does not affect the normal life of patients. Therefore, capsule endoscopy has a tendency to gradually replace traditional intubation gastroenteroscopy. [0003] Capsule endoscopes generally include a shell and a capsule core built into the shell. The capsule core is the core structure of the capsule endoscope, including but not limited to camera units, lighting units, image processing units, permanent magnets, batteries, Functional components such as signal transmission unit and control unit, wherein electroni...
