Abstract
The utility model relates to a medicine apparatus, in particular to a percutaneous kidney microscope, which is mainly suitable for treating the nephrolithiasis in the urology. The percutaneous kidney microscope comprises an outer sheath, an endoscope with an object lens system. The utility model is characterized in that the center line of the apparatus passage in the endoscope is parallel to the center line of the outer sheath, an angle is formed between the viewing system in the endoscope and the lens body, and a prism is arranged on the lower corner of the endoscope viewing system. The first lens in the object lens system is provided with an aspect angle, and the scope of the aspect angle is 6 degrees-15 degrees. The utility model solves the problem that the present percutaneous kidney microscope cannot be placed a hard surgical clamp.
Description
Technical field
This utility model relates to a kind of medical device, particularly a kind of PCN, and it mainly is suitable for treatment renal calculus usefulness in the Urology Surgery.
Background technology
Its structure of PCN of the prior art as shown in Figure 1, it mainly is made up of epitheca I ' and the II ' of endoscope, in this endoscope in the endoscope instrument channel 12 ' be curved shape, promptly instrument channel 12 ' centrage is a broken line.The PCN of this kind structure can only be placed soft operating forceps in the process of operation, and can not place rigid operating forceps, can not satisfy the requirement of operation.During operation, inconvenient operation.
Summary of the invention
The technical assignment of the technical problems to be solved in the utility model and proposition is to overcome above-mentioned defective, and it is collinear PCN that a kind of reasonable in design, scope of application centrage wider, that can place rigid operating forceps and instrument channel are provided.
The technical scheme in the invention for solving the above technical problem is: this kind PCN, comprise epitheca, have the endoscope of objective system, it is characterized in that: the centrage of instrument channel is parallel with the centrage of epitheca in the described endoscope, viewing system in the endoscope and the mirror body angle that tilts, and the corner below the endoscopic observation system is equipped with a prism, first eyeglass in the objective system has a viewing directional angle, and the magnitude range of viewing directional angle is 6 °～15 °.
This best viewing directional angle that uses first eyeglass of novel described objective system is 12 °.
This utility model compared with prior art, have the following advantages and effect: the project organization of PCN is more reasonable, the centrage that has guaranteed the instrument channel 12 in the PCN is parallel with the centrage of epitheca I, the centrage that is instrument channel 12 is a straight line, instrument channel 12 is a straight passage, solved the problem that to place rigid operating forceps in the existing PCN, thereby made that this utility model scope of application is wider.In addition, can also place some special operating theater instruments, make PCN in some special field of surgery, also can use, as fields such as trajectory rubble, electrohydraulic lithotripsies.

The specific embodiment
Referring to Fig. 2, Fig. 4, present embodiment mainly is made up of epitheca I and the II of endoscope, and epitheca I is enclosed within on the II of endoscope.Epitheca I mainly is made up of sheath pipe 1, sheath body 2, collar 3 and water valve 4, and sheath pipe 1 is connected with sheath body 2, and collar 3 and water valve 4 are installed on the sheath body 2.Epitheca I is enclosed within on the II of endoscope, is fixed on the II of endoscope by the collar on the sheath body 23.
Referring to Fig. 3, Fig. 6, the II of endoscope is mainly resembled lens 6, mirror body 7, light beam joint 8, viewing system 9, eye end connecting tube 10, eyepiece hood 11, instrument channel 12 and eyepiece system 13 and is formed by mirror pipe 4, objective system 5, prism 14, commentaries on classics.Commentaries on classics resembles lens 6, objective system 5 is formed by many set of contact lenses with eyepiece system 13.Objective system 5 and image rotation lenses 6 are installed in mirror pipe 4.Light beam joint 8, viewing system 9 are installed on the mirror body 7.Viewing system 9 is with respect to mirror body 7 angle [alpha] that tilted, and the size at the α angle in the present embodiment is 45 °, and the scope at α angle can be 0 °～90 °.Viewing system 9 other ends in the endoscope link to each other with eye end connecting tube 10, and eyepiece system 14 is installed in viewing system 9 and the eye end connecting tube 10.Eyepiece hood 11 covers on eye end connecting tube 10 ends, can dismantle as required.Instrument channel 12 is a straight passage, and instrument channel 12 is passed mirror body 7, is supported by mirror body 7.Prism 14 is installed in the corner, below 17 that is positioned at endoscopic observation system 9, is installed on the prism table 15, and prism table 15 is arranged on the outer end of instrument channel 12.
Referring to Fig. 5, in order to guarantee observing effect the best of this moment, first eyeglass 18 end face in the objective system 5 have certain gradient to be installed, and makes in the objective system first eyeglass 18 that the viewing directional angle β of corresponding size is arranged by this angle, and the scope at β angle is 6 °～15 °.The angle of the best of viewing directional angle β is 12 °, at this moment the viewing system observing effect the best in the present embodiment.In addition, the front end face of first eyeglass 18 can also need to glue together a screening glass.Image rotation lenses 6 is installed on objective system 5 rears, and the inverted image of objective system 5 being collected by image rotation lenses 6 transfers erect image to and passes to eyepiece system 13 by prism 14.Thereby make operation in the operation more convenient, observe more clear.
By the viewing system in the endoscope 9 is improved design, and prism 14 that the centrage that has guaranteed the instrument channel 12 in the PCN is set is parallel with the centrage of epitheca I, the centrage that is instrument channel 12 is a straight line, and instrument channel 12 is a straight passage.The end face of first eyeglass 18 has a gradient simultaneously, makes viewing system that the viewing directional angle of the observation an of the best be arranged.Solved and to have placed rigid operating forceps problem in the existing PCN, thereby made that this utility model scope of application is wider.Can place some special operating theater instruments in addition, in some special field of surgery, also can use, as field of surgery scopes such as trajectory rubble, electrohydraulic lithotripsies.
