Abstract
The invention relates to an endoscope with a swingable head end. The endoscope comprises a light source, a light transmission optical fiber, an imaging optical fiber, an image transmission optical fiber and an image display device, wherein both the imaging optical fiber and the light transmission optical fiber are arranged in a sheathing catheter. The sheathing catheter is composed of a first sheathing catheter and a second sheathing catheter which are mutually hinged, and a slide groove is axially arranged in the outer wall of the first sheathing catheter. The endoscope further comprises a swing driving device which mainly comprises a gear, a rack and a push-pull part, the rack is arranged in the slide groove, the gear meshes with the rack and can freely rotate, and one end of the rack, distant from the gear, is connected with the second sheathing catheter through the push-pull part. The head end of the endoscope can swing to different angles according to needs, so that the endoscope can be applicable to diagnosis of any part in the urinary bladder and has no blind area in sight in the bladder. Therefore, the defects of existing cystoscopes are overcome, diagnosis accuracy of the cystoscopes is overcome, and as adjustment is totally mechanical, energy resource can be saved, complexity of the endoscope is reduced, and feasibility is enhanced.
Description
Technical field
The present invention relates to medical instrument technical field, be specifically related to the swingable endoscope of a kind of head end.
Background technology
Along with the development of endoscopic technic, cystoscope becomes the Main Means of diagnosis of urinary diseases, owing to can looking at the characteristics such as lower observation pathological changes size, position straight, higher to the diagnostic value such as tumor of bladder, complicated calculus, and to determining that operation plan is of great importance, and coordinate electric knife or get stone calculi breaking device and can treat disease simultaneously.But because existing cystoscope is straightforward hard mirror, inflexibility, becomes straightforward cystoscopic blind area for bladder front side wall and near near pathological changes internal urethral orifice, thereby has increased rate of missed diagnosis, increases patient's misery and burden.Though report has the application of soft lens at present, because its cost is higher, popularization is poor, has limited range of application.
Summary of the invention
The object of the invention is the deficiency for solving the problems of the technologies described above, provide a kind of head end swingable endoscope, can carry out as required bending in various degree, applicable to the diagnosis at any position of intravesical, can accomplish non-blind area to the intravesical visual field, make up existing cystoscopic deficiency.
The present invention is the deficiency solving the problems of the technologies described above, the technical scheme adopting is: the endoscope that a kind of head end is swingable, comprise light source, optical coupling part, lose optical fiber, imaging fibre, defeated picture optical fiber, image coupling unit and image display device, light source is connected and is lost optical fiber by optical coupling part, imaging fibre is connected with image coupling unit, image coupling unit connects image display device by defeated picture optical fiber, described imaging fibre and lose optical fiber and be all arranged in sheath pipe, described sheath pipe is made up of sheath pipe I and sheath pipe II, sheath pipe I and sheath pipe II are hinged by bearing pin, on the outer wall of sheath pipe I, be provided with vertically chute, endoscope also comprises oscillatory gearing mechanism, driving device is mainly by gear, tooth bar and pull-push piece composition, tooth bar is fastened in chute, and can produce axial displacement along chute, described gear is arranged on sheath pipe I one end away from sheath pipe II, wheel and rack is intermeshing and free to rotate, tooth bar is connected with sheath pipe II by pull-push piece away from gear one end, described pull-push piece is plastic material.
Described sheath pipe I is in the enclosure sheathed.
Described gear is connected with thumb wheel.
beneficial effect
Endoscope of the present invention, its head end can carry out swing in various degree as required, applicable to the diagnosis at any position of intravesical, can accomplish non-blind area to the intravesical visual field, make up existing cystoscopic deficiency, obviously improve cystoscopic diagnosis rate, and its regulative mode is pure theory of mechanics, also can energy savings, reduce the complexity of device, increase feasibility.
