Description
Technical field
This utility model relates to a kind of medical hard-tube endoscope device, belongs to the technical field of minimally invasive medical apparatus.
background technology
Advantages such as rigid pipe endoscope is a kind of Medical Instruments for medical diagnosis and operation, adopts the Minimally Invasive Surgery of endoscope, has wound little, and post-operative recovery is fast and being day by day used widely.Rigid pipe endoscope is mainly by outer tube, main body, and eyepiece hood, the joints of optical fibre form, as shown in Figure 1.In application, the joints of optical fibre are connected with lighting fiber, import in endoscope illumination operation visual area in order to the light that cold light source is sent.Eyepiece hood is connected with video camera adapter, in order to visual area image amplification imaging that endoscope is become to ccd video camera, thereby can on monitor, observe easily visual area image.At present; the main mode of operation of the Minimally Invasive Surgery of domestic application rigid pipe endoscope is: adopt disposable soft plastic protective sleeve sterilize that the needs part tactile and that operate that catches (is mainly comprised to endoscope main body; the joints of optical fibre; partial illumination optical fiber; video camera adapter, camera head) protect, to avoid video camera adapter; lighting fiber, repeatedly sterilizing of camera head and service life of reducing this part apparatus.Current, the general configuration in 90 ° of the rigid pipe endoscope joints of optical fibre and outer tube and main body, this structure to the adverse effect of current domestic conventional mode of operation is: protective sleeve is larger, and inconvenient operation is difficult for realizing one-handed performance; Lighting fiber in use can be converted into the bending angle of nearly 90 °, and lighting fiber is easy to damage.
utility model content
Technical problem to be solved in the utility model is to overcome the adverse effect of existing rigid pipe endoscope structure to operation technique, provide a kind of simple in structure, easy to operate, can improve the lighting fiber medical hard-tube endoscope device in service life, the technical scheme adopting is that thereby the structure of main body changes and the joint face of the joints of optical fibre by changing, and reduces the angle of the joints of optical fibre and optical axis.Below in conjunction with accompanying drawing, describe the technical solution of the utility model in detail.
A kind of medical hard-tube endoscope device, containing mirror pipe (1), main body (2), eyepiece hood (3), the joints of optical fibre (4), mirror pipe (1) outside is the stainless steel tube of diameter 1.5 ~ 10mm, include image-forming objective lens group, image rotation group and illumination fiber optic bundle, main body (2) is rustless steel polyhedron, eyepiece hood (3) is made by rustless steel or medical plastic, include eyepiece optics group, mirror pipe (1) welds with the left surface of main body (2), eyepiece hood (3) welds or glueds joint with the right flank of main body (2), mirror pipe (1) is connected in coaxial mode by main body (2) with eyepiece hood (3), the optical axis (5) that the axis forming is rigid pipe endoscope, the axle shell body that the shell of the joints of optical fibre (4) is stainless steel material, include illumination fiber optic bundle, it is characterized in that, between the right flank of main body (2) and bottom surface, contain a tapered plane (21), the angle theta of tapered plane (21) and optical axis (5)
1between 30 ° ~ 60 °, the joints of optical fibre (4) are connected with main body (2) in the mode perpendicular to tapered plane (21), corresponding, the angle theta of the axis of the joints of optical fibre (4) and optical axis (5)
2between 60 ° ~ 30 °.
The beneficial effects of the utility model are: the angle of the joints of optical fibre and optical axis is less, can effectively dwindle the size of protective sleeve, and doctor can singlehandedly realize operation, operates more convenient; In addition, the bending angle of external lighting fiber in protective sleeve is less, and lighting fiber is frangibility not, can effectively improve the service life of lighting fiber.
Accompanying drawing explanation
Fig. 1 is the structural representation of current conventional a kind of medical hard-tube endoscope device.
Fig. 2 is the structural representation of a kind of medical hard-tube endoscope device of the present utility model.
The specific embodiment
Now describe in conjunction with the accompanying drawings and embodiments the technical solution of the utility model and operation principle in detail.
Embodiment 1: the present embodiment has and the identical structure of technique scheme, and the key technical indexes is enumerated as follows:
Mirror pipe (1) diameter 10mm, tapered plane (21) and optical axis (5) angle theta
1be 45 °, the axis of the joints of optical fibre (4) and optical axis (5) angle theta
2it is 45 °.
Operation principle is: when doctor operates; protective sleeve is inserted in to main body (2) left surface from mirror pipe (1) front end; then protective sleeve is enclosed within protective sleeve by main body (2), eyepiece hood (3), the joints of optical fibre (4), partial illumination optical fiber, video camera adapter together with camera head; because the joints of optical fibre (4) are 45 ° with the angle of optical axis (5); less by approximately 30% perpendicular to the size of optical axis (5) direction than traditional rigid pipe endoscope edge along the size perpendicular to optical axis (5) direction in protective sleeve, doctor can realize the singlehanded protective sleeve of holding and operate.In addition, the maximum bending angle of lighting fiber is 45 °, greatly reduces the probability that lighting fiber fractures.
