20130217969 | ENDOSCOPE DEVICE - In a tip face of an insertion part of an endoscope, gas is discharged from a plurality of air supply ports formed around an observation window, and air currents are generated. This removes suspended matter, such as oil particles and fat particles, from an imaging visual field. The interval between adjacent air supply ports of the air supply port is specified so that the gas around air currents is caught in the air currents by the air currents without being directed towards the imaging lens. The surrounding gas by the air currents being discharged is pulled in the imaging direction along with the air currents. Since the surrounding gas induced by the air currents is prevented from being induced in the direction of the imaging lens, the imaging lens can be prevented from being contaminated by an unnecessary object. | 08-22-2013 |

20140350343 | DISPOSABLE ENDOSCOPE - Provided is a disposable endoscope that enables simple treatment by capturing an image inside a body as a moving picture or photo, and in particular, that enables replacement of a probe portion inserted into the body and that preemptively prevents infection in patients due to repeated usage. The disposable endoscope includes: a main body that is connected to a monitor, and in front of which a light emitting portion and a light receiving portion are arranged in parallel; a light emitting fiber that guides light from the light emitting portion toward an object to be examined; a light receiving fiber that guides light reflected from the object to be examined toward the light receiving portion; and a light adjustment unit that is placed within the protective tube that is adjacent to ends of the light emitting fiber and the light receiving fiber and that adjusts a position of light toward the object to be examined or light reflected from the object to be examined, wherein the light receiving fiber guides light that is reflected from the object to be examined through the light adjustment unit toward the light receiving portion. A probe portion inserted into a body of a patient or a user is used only once so that cross-contamination caused by repeated usage can be prevented in advance. A structure of the disposable endoscope is simple so that costs can be reduced due to reduction in a unit cost of production. A portion in which photographing of a moving picture or photo is substantially performed can be precisely controlled so that a precise diagnosis can be carried out. Photographing of a moving picture or photo with high resolution can be performed using a plurality of mirrors and lenses so that the quality of a patient's treatment or therapy can be improved. | 11-27-2014 |
