The specific embodiment
The invention will be further described below in conjunction with accompanying drawing.
As depicted in figs. 1 and 2, the present invention includes the operating portion 1 that is provided with bending section control device 2, one side of operating portion 1 is connected with camera lens main body 5 by shank 3, its opposite side is connected with main frame 7 by protective casing 6, be provided with the water filling, gas injection and the suction catheter that are connected with camera lens main body 5 in the protective casing 6, be provided with optocoupler components in the camera lens main body 5, the front end face of camera lens main body 5 is provided with object lens window 13, biopsy forceps pipeline opening 14 and water filling, the gas injection mouth of pipe 15; The front end face of described camera lens main body 5 is an arc convex; light emitting diode 8 is installed on the described arc convex; light emitting diode 8 is connected with an end of power line 9, and the other end of power line 9 is connected with brightness controlling device 12 by shank 3, operating portion 1, protective casing 6 and plug 10 and main frame 7 interior power supplys 11.
As shown in Figure 3, described camera lens main body 5 is a spindle.
As shown in Figure 4, described camera lens main body 5 is an olive shape.
As shown in Figure 5, described camera lens main body 5 is eccentric shape.
Camera lens end face of the present invention has adopted the design of arc convex, resistance coefficient when endoscope lens is inserted reduces to 0.52 by 1.2 of the flush shape in traditional cylinder plane, and the degree that the insertion of endoscope is more prone to, makes human body insert position mucosal tissue damage is reduced to minimum; The diameter of its camera lens main body 5 still is designed to only 15mm of traditional 9.8mm to 11.0mm, length; Because the very thin power line 9 of shank 3 interior employings has replaced original optical fibers optical cable than thick and fearness tractive, extruding, therefore reduced the space hold in the shank 3, so under the situation of not dwindling the endoscopic biopsy pipeline, can make the diameter of shank 3 reduce to 6.8mm to 8.0mm by traditional 9.8mm to 11.0mm, this diameter that has just formed camera lens main body 5 is big, the shape that shank 3 is thin.In the process that endoscope inserts, the patient has the seemingly physiological sensation of the group of eating, and because of endoscope inserts attenuating suddenly of shank of back and reducing suddenly of pressure and frictional resistance, patient's misery is alleviated suddenly, helps the inspection and the mirror treatment down of endoscope.Owing to adopted high brightness, low in calories, life-span is long, response is fast, volume is little, nontoxic, sturdy and durable, and cheap light emitting diode 8 is as the light source of endoscope of the present invention, its brightness with the prolongation of service time reduce very little, this will make the picture quality of endoscope forever remain on optimum state, and because power line 9 has replaced optical fibers, thereby shank 3 can be run business into particular one, but its movable detecting apparatus pipeline still is the thick pincers road of diameter 2.8mm, this will satisfy the instructions for use of all endoscope's auxiliary treatment apparatuses to the pincers road, the present invention not only can not descend because of attenuating of shank 3 makes performance, increasing on the contrary, (the camera lens main body 5 of existing endoscope is identical with the diameter of shank 3, diameter is its camera lens main body 5 of thick pincers road endoscope of 2.8mm and the equal 9.8mm to 11.0mm of diameter of shank 3, want to make endoscope to attenuate, can only make the diameter of biopsy pipeline reduce to 2.0mm, the auxiliary treatment apparatus of a lot of endoscopies can not be used) by 2.8mm.The present invention adopts light emitting diode 8 to replace the cold light source and the optical fibers of conventional endoscope, and its cost and cost are very low, just cold light source and fiber-optic several percent.In addition, owing to replaced two optical fiberses with the very little light emitting diode 8 of volume in the camera lens main body 5, thus make the space enlargement in the camera lens main body 5, can select slightly bigger optocoupler components (CCD) like this for use, its cost is further descended.Light emitting diode 8 does not need outside cold light source, the present invention only needs that volume is very little, the main frame 7 of very light in weight, DC charging battery 11 is set in the main frame 7 is light emitting diode 8, CCD and monitor power supply, thereby prevented the influence that brings to splanchnoscopy because of having a power failure, also can be at the non-Electric region splanchnoscopy of meeting an urgent need.
