Abstract
The utility model discloses an illuminating system of a medical robot for intestines and stomach scanning which is characterized by including an annular light-gathering prism and a LED light source behind the annular light-gathering prism; the top part of the annular light-gathering prism is provided with a transflective surface; beams enter from the bottom surface of the annular light-gathering prism and arrive at the transflective surface; partial beams after being refracted by the transflective surface illuminate the right ahead direction and partial beams after being refracted by the transflective surface exit from the side surface of the annular light-gathering prism to illuminate the side surface. The illuminating system of the medical robot for intestines and stomach scanning not only can illuminate the right ahead direction, but also has broader illuminating scope on the side surface and shorter distance of light, has broader shooting scope and brightness on walls of intestines and stomach, has clear shot images, and is beneficial for diagnosis of doctors.
Description
Technical field:
This utility model relates to the illuminator that a kind of medical the intestines and stomach scans robot.
Background technology:
The image of traditional shooting human body the intestines and stomach generally is to utilize a pipeline to pass people's throat or anus, utilize fiber lens could take the image of the intestines and stomach, this brings discomfort even causes damage to the patient, the appearance that a kind of medical the intestines and stomach scans robot has solved above problem, as shown in Figure 1, after the people is scanned eating of the A of robot to the medical the intestines and stomach of capsule-type, the intestines and stomach scanning robot enters the intestines and stomach along esophagus, at the moving process photographic images, get rid of from anus at last, all filmed images all are recorded in the storage chip the inside of the intestines and stomach scanning A of robot, and the doctor can carry out medical diagnosis by the view data that special equipment (for example computer) reads inside the storage chip.As shown in Figure 2, general the intestines and stomach scanning robot is made up of four parts: power-supply system, image capturing apparatus, illuminator and image storage.This utility model is to improve at illuminator.
As shown in Figure 3, the medical the intestines and stomach of existing capsule-type scanning robot illuminator comprise be located in the capsule-type housing 01 by object lens 02 and be positioned at the illumination LED lamp 03 at object lens 02 rear.There is following defective in this illuminator: 1, Zhao She the angle of visual field is bigger, but mainly concentrates on dead ahead, and the range of exposures of both sides is narrow, do not utilize the image of taking observation gastrointestinal sidewall, so the coverage of intestinal wall is little, influences image and judges unfavorable diagnosis; 2) whole illuminator is utilized irrational distribution to light.
Summary of the invention:
It is a kind of more reasonable to the light utilization that the purpose of this utility model is to provide, and the side-irradiation scope is wide more, brightness of illumination is uniform more, make the clear more medical the intestines and stomach of photographic images scan the illuminator of robot.
A kind of medical the intestines and stomach scans the illuminator of robot, it is characterized in that: it comprises annular optically focused prism and is positioned at the led light source at annular optically focused prism rear, annular optically focused prism top has the semi-transflective reflective face, light enters from the prismatical bottom surface of annular optically focused, arrive the semi-transflective reflective face, part light illuminates dead ahead through semi-transflective reflective face refraction back transmission, and another part light is gone out from the prismatical side of annular optically focused through semi-transflective reflective face reflection back, illuminates the side.
Above-mentioned described led light source comprises two LED lamps at least, and the LED lamp is along annular optically focused prism uniform distribution, and the LED lamp is arranged on the circular base.
The prismatical semi-transflective reflective face of above-mentioned described annular optically focused is a free form surface.
The prismatical side of above-mentioned described annular optically focused is the face of cylinder, and the bottom surface is plane or tire curved surface.
Be coated with the semi-transflective reflective film on the surface of above-mentioned described semi-transflective reflective face.
The prismatical crown center of above-mentioned described annular optically focused forms cavity, and the side wall surface of cavity forms the semi-transflective reflective face.
This utility model compared with prior art has following advantage: the semi-transflective reflective face that 1) utilizes annular optically focused prism top to have, light enters from the prismatical bottom surface of annular optically focused, arrive the semi-transflective reflective face, part light illuminates dead ahead through semi-transflective reflective face refraction back transmission, another part light is gone out from the prismatical side of annular optically focused through semi-transflective reflective face reflection back, illuminate the side,, light utilization wide more to the intestines and stomach wall coverage face more rationally evenly, brightness of image is even, make photographic images clear, be beneficial to diagnosis.2) above-mentioned described led light source comprises two LED lamps at least, and the LED lamp is along annular optically focused prism uniform distribution, and the LED lamp is arranged on the circular base, makes brightness more even; 3) the prismatical crown center of above-mentioned described described annular optically focused forms cavity, and the side wall surface of cavity forms the semi-transflective reflective face, and top semi-transflective reflective face is a free form surface, the side is the face of cylinder, and the side is the face of cylinder, and the bottom surface is plane or tire curved surface, simple in structure, easy to manufacture.

The specific embodiment:
As Fig. 4, Fig. 5, Fig. 6 and shown in Figure 7, a kind of medical the intestines and stomach scans the illuminator of robot, comprise annular optically focused prism 1 and the led light source 2 that is positioned at annular optically focused prism 1 rear, annular optically focused prism 1 top has semi-transflective reflective face 11, light enters from the bottom surface 13 of annular optically focused prism 1, arrive semi-transflective reflective face 11, part light reflects the back transmissions through semi-transflective reflective face 11 and illuminates dead ahead, another part light is gone out from the prismatical side 12 of annular optically focused through semi-transflective reflective face 11 reflection backs, illuminates the side.Led light source 2 comprises two LED lamps 22 at least.LED lamp 22 is along annular optically focused prism 1 uniform distribution.LED lamp 22 is arranged on the circular base 21.The semi-transflective reflective face of annular optically focused prism 11 is free form surfaces, and the side 12 of described annular optically focused prism 1 is the face of cylinder, and bottom surface 13 is plane or tire curved surface.Be coated with the semi-transflective reflective film on the surface of described semi-transflective reflective face 11.The crown center of described annular optically focused prism 1 forms cavity 14, and the side wall surface of cavity 14 forms semi-transflective reflective face 11, and the diapire 15 of cavity 14 is plane or curved surface.This utility model is except can illuminating the dead ahead, and lateral illumination zone is relatively wider and distance light is short, and is wide more to the intestines and stomach wall 3 coverage faces, brightness is even, and image taking is more clear, is beneficial to diagnosis.
