Embodiment Construction
[0021] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.
[0022] Such as figure 1 As shown, an eyepiece device with an adjustable center position according to the present invention includes an eyepiece 50, an inner sleeve 110, an eyepiece sleeve 100, an imaging fiber 220, a fixing sleeve 210, an imaging fiber fixing seat 200 and a base 300, wherein , the extension direction of the imaging fiber 220 is the optical axis direction, that is, the z axis, and the plane perpendicular to the z axis is the xy plane formed by the x and y axes; the imaging fiber 220 transmits the image to the end 221 in the form of light, and the eyepiece 50 uses The image transmitted by the imaging fiber 220 is enlarged so that the operator can watch from the observation end 130; the imaging fiber 220 can move in x, y, and z axes ...

The invention discloses an ocular-lens device adjustable in center position. The ocular-lens device includes an ocular lens and an imaging fiber. An ocular-lens sleeve is arranged at the periphery of the ocular lens. The ocular-lens sleeve is arranged on a base. The optical axis of the imaging fiber is a z axis and a plane vertical to the z axis is an x-y plane. The ocular-lens device with the adjustable center position also includes a planar-axis adjustment mechanism and a vertical-axis adjustment mechanism. The imaging fiber is capable of moving on the x-y plane relative to the ocular lens through the planar adjustment mechanism and moving in the direction of the z axis relative to the ocular lens through the vertical adjustment mechanism. The beneficial effects of the ocular-lens device with the adjustable center position are that manual adjustment of the focal length between the imaging fiber and the ocular lens is realized and the imaging fiber is made be located at the center of the ocular lens so that an image observed by an operator is clear and located at the center of the ocular lens and thus better observation of the operator is facilitated; the ocular-lens device adjustable in center position can be used under a condition that a device is not disassembled so that operability of production maintenance is improved significantly and the ocular-lens device is higher in practicality.
Description
technical field [0001] The invention relates to the field of medical instruments, in particular to an eyepiece device with an adjustable center position. Background technique [0002] Fiber endoscopes used in medical treatment are usually composed of imaging fibers and imaging eyepieces. The imaging fibers are used to transmit images in the form of light. The eyepieces are used to magnify the image of the imaging fiber viewfinder. The operator can see through the observation eyepieces Framing of imaging fibers. [0003] In the existing eyepiece device, because it is difficult to ensure that the processed parts fully conform to the design drawing size during production, the image fiber end face of the assembled eyepiece is often not in the best imaging position of the eyepiece, and it is difficult to obtain a clear and centered image. When the user observes the eyepiece, the image deviates from the line of sight, which is not convenient for the user to observe better. Cont...
