Abstract
The invention discloses a medical lighting video camera, which comprises a fixed installation frame, a video camera, a plurality of light-emitting diode (LED) light sources and a plurality of first lenses, wherein the video camera is arranged at the central position of the fixed installation frame; a plurality of LED light sources are distributed on the fixed installation frame along the circumferences of a plurality of concentric circles by taking the video camera as a center; a plurality of first lenses correspond to the LED light sources one by one and are arranged in front of the corresponding LED light sources; and light rays emitted by a plurality of LED light sources are aggregated towards the target position on an axis extension line positioned on the video camera by a plurality of lenses. In the medical lighting video camera, the video camera is arranged at the optimum operating position, and a camera space without interference and the optimum camera space in which illuminance, color rendering indexes and color temperature are consistent are provided for the video camera to achieve the effect of combining real-time remote medical treatment, teaching, data storage and medical lighting effectively.
Description
Technical field
The present invention relates to the medical illumination field, especially relate to a kind ofly for medical lighting video camera, can be used for that (long-range) medical treatment, teaching and data are preserved in real time.
Background technology
In curative activity (operation), need major surgery for some, often need to carry out real time remote medical treatment, teaching and data and preserve.And this process just need to be shot with video-corder in curative activity (operation), shoots with video-corder and should avoid the people that is subject to or the interference of equipment in process in image pickup scope, guarantees again the image stabilization of transmission, and color is consistent with tissue.In order to guarantee that lighting for medical use equipment provides an illumination, color rendering index, 3D region that colour temperature is consistent to the zone of the curative activity (operation) that carries out.At present, the luminaire being used for real time remote medical treatment, teaching and data preservation, mainly adopt following two kinds of methods:
(1) adopt to increase outside the luminaire of curative activity (operation) and hang a video camera realization and shoot with video-corder process.Yet, adopt this method video camera can not arrive patient's wound directly over, can not accurately reflect the process of operative treatment, and patient's wound and tissue are made the required image of accurate judgement; Simultaneously, owing to hanging over outward outside lighting for medical use equipment, the doctor who performs a surgical operation and other staff enter the visual field of making a video recording, and disturb shooting; In addition, owing to hanging over outward outside lighting for medical use equipment, in medical treatment (operation) activity, easily participated in personnel's touching of curative activity, and cause video camera to rock, thereby cause image unstable.In this case, can not carry out the real time remote medical treatment, otherwise can cause serious consequence, only preserve as teaching and data, relatively poor because of the effect of above-mentioned its teaching of reason, reach the data of preserving also imperfect.
(2) use with the lighting for medical use equipment of halogen lamp as the routine of light source, the light that halogen lamp sends reflexes to the area of illumination that needs by reflection shield, also be provided with an operating grip in this illuminator, in order to regulate the position relationship of halogen lamp and reflection shield, replace operating grip to be arranged on the below of halogen lamp in video camera, the process of operative treatment can accurately be reflected in this position that makes video camera above showing up.Due to the inside of video camera in lighting for medical use, so the equipment that do not have disturbs shooting, personnel to touch and cause video camera to rock, thereby cause the phenomenon of image shakiness.Yet due to being substituted by video camera of the operating grip of adjusting focal length, make the relative position relation of halogen lamp and reflection shield fix, and then luminaire can only provide a best area of illumination, and this makes troubles for normal curative activity (operation), or even hidden danger.Due to patient's wound be three-dimensional, depth arranged, the area of illumination that depth is limited, the illumination of the shooting that offers is also extremely undesirable, when implementing the real time remote curative activity, can not provide best image, to such an extent as to affect tele-medicine to the correct judgement of wound and tissue.
Summary of the invention
