Embodiment 1

[0054] figure 1 It is a structural diagram of the capsule-shaped shell of the present invention, which includes a front end 11 , a shell body 12 and a tail 13 . The front end 11 is transparent, and the camera device is placed in a position corresponding to the inside. The front end 11 , the shell body 12 and the tail 13 are all made of polycarbonate and the outer surfaces are all coated.

[0055] The outer surface of the front end 11 is as figure 2 In this way, TiO is plated sequentially with 14.96nm by gel method, vacuum sputtering method and vacuum evaporation method. 2 , 32.3nm SiO 2 , 49.78nm TiO 2 , 15nm SiO 2 , 37.86nm TiO 2 , 93.01nm SiO2 2 AR coating is formed and finally CF 3 (CF 2 ) 5 (CH 2 ) 2 SiCl 3 In SiO 2 The outer surface of the film is nano-coated. The thickness of each layer of the anti-reflection film can be appropriately adjusted according to the needs. The following embodiments refer to the thickness of this embodiment or make adaptive modi...

Embodiment 2

[0059] figure 1 It is a structural diagram of the capsule-shaped shell of the present invention, which includes a front end 11 , a shell body 12 and a tail 13 . The front end 11 is transparent, and the camera device is placed in a position corresponding to the inside. The outer surface of front end 11, shell main body 12 such as image 3 TiO 2 , SiO 2 、TiO 2 , SiO 2 、TiO 2 , SiO 2 AR coating is formed and finally CF 3 (CF 2 ) 7 (CH 2 ) 3 SiF 3 In SiO 2 The outer surface of the film is nano-coated. The outermost layer of tail 13 is not plated with CF 3 (CF 2 ) 7 (CH 2 ) 3 SiF 3 This material makes the wetting angle of the outermost surface of the tail part 13 smaller than the wetting angle of the front end 11 and the shell main body 12, and the friction force of the outermost surface of the tail part 13 is greater than that of the front end 11 and the shell main body 12. When this capsule-shaped shell is used for a capsule When the endoscope shell is used, ...

Embodiment 3

[0063] Capsule shell remains as figure 1 As shown, it includes a front end 11 , a shell body 12 and a tail 13 , which are composed of polysulfone (PSF). The outer surface of the front end 11, the shell main body 12 and the tail 13 as figure 2 TiO 2 , SiO 2 、TiO 2 , SiO 2 、TiO 2 , SiO 2 AR coating is formed and finally CF 3 (CF 2 ) 5 (CH 2 ) 2 SiCl 3 In SiO 2 The outer surface of the film is nano-coated. When such a capsule shell is used for the shell of a capsule endoscope, the nanoscale single-layer low surface energy polymer material on the surface of the capsule shell makes the surface of the capsule non-stick, effectively reducing the missed detection rate of the capsule endoscope.

Abstract

The invention provides a capsule-shaped shell. The capsule-shaped shell comprises a front end, a shell body and a tail, the front end, the shell body and the tail are all made of biocompatible materials, the front end is transparent, and the outer surface of the front end is provided with an anti-reflection film and an anti-adhesion film located outside the anti-reflection film. The capsule-shaped shell and a capsule endoscope with the capsule-shaped shell effectively solve the problem that the surface of a front end is likely to be stained with digestive tract mucus in the examining process at present, and consequently an image is not clear, and the omission rate of capsule endoscope examinations can be effectively reduced.

Description

technical field [0001] The invention relates to a casing, in particular to a capsule-shaped casing, a preparation method for the capsule-shaped casing and a capsule endoscope with the capsule-shaped casing. Background technique [0002] With the development of large-scale integrated circuit technology, MEMS, wireless communication, and optical technology, capsule endoscopy, as an effective method for diagnosing intestinal diseases, has been widely studied and developed rapidly. Capsule endoscopes generally include a capsule shell, lighting device, camera device, radio frequency transmitter, and battery. After the subject swallows the capsule endoscope, the pictures taken by the camera device placed at the transparent front end are wirelessly transmitted to the outside of the body. The inspectors made a reasonable judgment on the condition of the subject through the received pictures. Compared with the insertion-type gastrointestinal endoscope, the biggest advantage of the c...
