Detailed Description

The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are presented herein only to illustrate and explain the present invention, and not to limit the present invention.

Example (b): as shown in fig. 1-3, the utility model relates to a special protective sheath of endoscope of anti-halation, including protective sheath body 6, protective sheath body 6 divide into three part, and three part is pipe box 2, hose 1 and lens cover 3 respectively, the both ends of hose 1 respectively with pipe box 2, lens cover 3 interconnect, the size of lens cover 3 and the size of endoscope camera lens correspond to each other, and the inner wall of lens cover 3 is fixed and is provided with printing opacity coating 4, the thickness of printing opacity coating 4 is the quarter of the wavelength of visible light, when the visible light that the cold light source of endoscope sent, can produce the first layer reverberation when seeing through purpose-built printing opacity coating 4 surface, can form the reverberation of second floor when continuing to pass through purpose-built printing opacity coating 4 and camera lens, the reverberation of second floor can continue to pass through printing opacity coating 4, because the thickness of printing opacity coating 4 has been controlled to be the quarter of the wavelength of visible light, the reverberation of second floor reflects back after getting into the coating, just be just in half of visible light, first layer reverberation and second floor difference is just in half, wave peak and wave crest and mutually offset, thereby fundamentally can's the phenomenon of halo appear around.

The middle part of the pipe sleeve 2 is movably sleeved with a fastening sleeve 5, the fastening sleeve 5 is made of silica gel, two sides of the fastening sleeve 5 are respectively provided with a square butt joint plate, the middle parts of the two square butt joint plates are fixed through a medical butt joint, the fastening sleeve 5 corresponds to the pipe sleeve 2 in size, and the whole thickness of the fastening sleeve 5 is smaller, so that the whole use of the pipe sleeve 2 is not influenced, and the effect of fixing the position between the endoscope and the pipe sleeve 2 is achieved.

The hose 1 is made of TPU, one end of the hose 1 is adhered to one end, opposite to the lens sleeve 3, of the lens sleeve 3 through glue, and the stable effect between the hose 1 and the lens sleeve 3 is kept.

The middle part of the lens sleeve 3 is hollow, a plurality of stepped mounting seats are preset in the middle part of the lens sleeve 3 and adapted to different endoscope lens joints, and meanwhile, an endoscope can be guided to smoothly enter the sleeve, so that medical personnel can operate the sleeve conveniently.

Lens sleeve 3 wholly divide into two parts, and its lens sleeve 3 is left headgear and right headgear respectively, and left headgear is conical, and bonds through glue between left headgear and the right headgear, the main insulating material of this lens sleeve 3, and this lens sleeve 3's material is soft, and the body is felt well, and suitable entering is in the human body chamber say.

The lens sleeve 3 is made of PETG material, the transmittance can reach more than 90%, the lens sleeve is a better optical material at present, and the lens sleeve can be matched with an endoscope to be used, so that the image effect and the resolution ratio of the endoscope can be fully ensured not to be influenced. Thereby ensuring the normal diagnosis of the doctor.

The working principle is as follows: the utility model discloses a, at first wrap up its endoscope through sleeve pipe 2, insert and observe in patient's health afterwards, accomplish effectively completely cut off scope and human chamber way when not influencing the interior inspection and use to avoid the subsequent washing of scope, sterile complicated work.

The inner wall of the lens sleeve 3 is fixedly provided with a light-transmitting coating 4, the thickness of the light-transmitting coating 4 is one fourth of the wavelength of visible light, when visible light emitted by a cold light source of the endoscope penetrates through the surface of the special light-transmitting coating 4, a first layer of reflected light is generated, when the visible light continuously passes through the special light-transmitting coating 4 and the lens, a second layer of reflected light is formed, and the second layer of reflected light continuously passes through the light-transmitting coating 4.

The thickness of the light-transmitting coating 4 is one fourth of the wavelength of visible light, the reflected light of the second layer is reflected back after entering the coating and is just one half of the visible light, the difference between the reflected light of the first layer and the reflected light of the second layer is just one half, and the wave crest and the wave trough are just mutually offset, so that the reflected light is shielded and cannot be gathered around the lens, and the occurrence of a halo phenomenon is fundamentally avoided.
