Detailed description of the invention
Below in conjunction with drawings and Examples, this utility model is further described.
As Figure 1-4.
A kind of endoscopic rotation device, it comprises the rotating operating handle 6 be arranged in hand-held portion 1, described rotating operating handle 6 is fixedly linked with ball bearing 6-2, ball bearing 6-2 is arranged in the rotary actuation tooth 6-1 of synchronous axial system, rotary actuation tooth 6-1 is set with main driving cingulum 8, main driving cingulum 8 is rotated by driven cingulum 8-2, driven cingulum 8-2 drives the driven pulley 2-6 being arranged on front end, mirror body insertion section 2 to rotate, and driven pulley 2-6 drives front end, insertion section 2-1 to rotate around the front end of mirror body insertion section 2.As shown in Figure 1, as shown in Figure 2, insertion end front end face as shown in Figure 4 for the profile of whole endoscope.Details are as follows:
As shown in Figure 1, endoscopic rotation device, is made up of Spin Control handle 6, rotary actuation tooth 6-1, ball bearing 6-2, main driving cingulum 8, steel wire 8-1, driven cingulum 8-2, limited block 2-4, gear trough of belt 2-5 and bending section driven gear 2-6.Rotary actuation tooth 6-1 wherein is coaxially fixedly connected with Spin Control handle 6, and by being fixed on the ball bearing 6-2 in mirror body hand-held portion 1 as its rotating shaft, thus both can rotate relatively, the two ends of bending section driven wheel 2-6 are fixedly embedded in mirror body insertion section 2, by the main driving cingulum 8 being built in gear trough of belt 2-5, steel wire 8-1, driven cingulum 8-2 is interconnected formed closed cingulum, when receiving main driving and bending the manipulation of joystick 6, this closed cingulum can be driven along the longitudinal orientation rotation of gear trough of belt 2-5, thus drive driven gear 2-6 left rotation and right rotation, and the angular distance range limited position block 2-4 rotated limits, to ensure that bending section driven gear 2-6 can not depart from driven cingulum 8-2, and the arbitrarily angled rotation of driven gear about 2-6 can be ensured, then index glass body insertion section front end 2-1 can be with to do front and back (or upper and lower) arbitrarily angled rotation, achieve rotatable bending object.
As shown in Figure 2, it is made up of parts such as mirror body hand-held portion 1, mirror body insertion sections 2 outline drawing of endoscope body of the present utility model.Mirror body hand-held portion 1 is containing mirror body camera interface 3, cold light source input port 4, fluid injection and apparatus mouth 5, rotating operating handle 6 parts and interface composition; Mirror body insertion section 2 comprises the composition such as front end, insertion section 2-1, mirror body insertion section sheath 2-2, bent node 2-7.Cold light source input port 4 wherein for accessing cold light source, to transmit illuminating bundle; Fluid injection and apparatus mouth 5 are for fluid injection and get biopsy, are convenient to clinician's treatment; Mirror body insertion section sheath 2-2 special medical elastomeric material is made, and has the characteristics such as pliability, non-corrosiveness, durability.When holding Spin Control handle 6 left and right directions and rotating, the leading section 2-1 of mirror body insertion section 2 bends in company with left and right (or up and down) direction Arbitrary Rotation, can detect the larger lesions position area image of tube chamber inner surface focus situation or downstream tube intracavity turning thus.
As shown in Figure 3, it is made up of image transmission optical fibre 3-1, planoconvex lens 3-2, cemented doublet 3-3 and CCD photoreceptors 3-4 endoscope eyepiece switching device 3-5.As this device object lens 7(Fig. 4) adopt be self-focusing microlens time, it is by after image transmission optical fibre, because of GRIN Lens generation is negative aberration, for this reason, in eyepiece adapting system device 3-5, have employed positive cemented doublet 3-3 to correct the negative aberration of GRIN Lens, ensure that self can not bring larger aberration; Consider that the picture in coherent fiber bundle image planes is made up of several discrete pixels, the amplification of coherent fiber bundle end face accomplishes generally to be no more than 20 times.In addition, in order to make the moderate length of adapting system, turn increase a planoconvex lens 3-2, when ensureing picture element, shorten the distance of adapting system, thus ensure that the volume of eyepiece switching device 3-5 reduces further, be more convenient for being integrated in mirror body camera interface 3, the hot spot of its imaging is little, has marginal aberration and the aberration of automatic calibration subject image.
As shown in Figure 4, its end face has self-focusing object lens 7, fluid injection and apparatus mouth 5, light-conductive optic fibre 4-1, mirror body insertion section sheath 2-2 and insertion section medium 2-3 to the front end face figure of mirror body insertion section.Fluid injection wherein and apparatus mouth 5 are for transfusion and get biopsy; The cold light of cold light source is imported focal zone by light-conductive optic fibre 4-1, thus position is detected in illumination; Self-focusing object lens 7 can to lesions position imaging, and the image transmission optical fibre connected through rear end face proceeds to eyepiece switching device 3-5; In addition, self-focusing object lens 7 are also replaceable is the lens of other specifications and characteristics, thus can improve the motility of use and reduce use cost; Insertion section medium 2-3 is formed in sheath 2-2 by special medical material, plays each channeling of isolation, and has pliability.The front end 2-1(of its insertion section is containing top end face) can realize left and right (or up and down) along with the turn of Spin Control handle 6 arbitrarily angled bending.
This utility model breaches endoscope on the market without bending apparatus or coarse simple and crude, the easily damaged drawback of bending apparatus.It has employed a kind of control device with accurate toothed belt wheel rotoflector, ensure that mirror body is detected the arbitrarily angled of end and turned to, and can be deep into the larger tube chamber of the focus body region of luminal structure complexity or turning.In addition, the object lens of mirror body leading section, not only configurable GRIN Lens, also replaceable is the lens of other specifications and characteristics, improves the motility of use, reduces use cost simultaneously.
This utility model does not relate to the part prior art that maybe can adopt all same as the prior art and is realized.
