Abstract
The present invention relates to a medical optical measurer for accurately measuring the range of diseases, coloboma bodies and prosthesis in surgical operations (particularly to in microsurgery operations). The medical optical measurer comprises an optical microscope. The present invention is characterized in that the optical microscope can be movably positioned and connected to an arched guide rail; one end of the arched guide rail is provided with a rotation positioning sleeve; a divided plate is arranged between an eyeglass and an object glass of the optical microscope. The present invention has the advantages of simple structure and convenient operation. Users can directly read the size of the object to be measured through an image of the object to be measured on the divided plate. With the method, a measuring tool does not need to be inserted into a body of a patient, the measure is accurate, the operational time is saved greatly, the pain of the patient is reduced, and the quality of the operation is increased.
Description
[technical field]
The present invention relates to a kind of Medical Optical Measuring Instrument, is the instrument of in the operation (especially microsurgery) extent of disease, damaged body and dummy accurately being measured.
[background technology]
Traditional surgery is to the assessment of extent of disease, damaged body size and to the simple survey instrument of the many dependence of the calculating of dummy size, as rule, protractor etc., these survey instruments have certain volume and length, and microsurgery does not often allow these instruments to insert in patient's body, or measure because of wild irregular can't the putting into of art, therefore the measurement in actual operation mainly relies on patient's experience and subjective estimation, the method error of this patient's subjective estimation is very big, is difficult to satisfy the requirement of high precision operation; Insert body if will make a kind of substituting, damaged body is repaired, because measuring error, the alternative body of inserting just need can conform to the size of damaged body through repeatedly finishing repeatedly, and this will certainly prolong operating time, increases the patient suffering, influences surgical effect.
[summary of the invention]
The technical assignment of the technical problem to be solved in the present invention and proposition is to overcome in the present microsurgery extent of disease, damaged body and dummy are measured inaccurate defective, and a kind of Medical Optical Measuring Instrument is provided.For this reason, the present invention takes following technical scheme:
Medical Optical Measuring Instrument, comprise an optical microscope, it is characterized in that being connected on the arch guide rail of this removable location of optical microscope, one end of described arch guide rail is provided with the rotational positioning cover, the arch guide rail can rotate around rotating locating sleeve, be connected with the dog screw that conflict puts in rotational positioning on the arch guide rail, be provided with graticule between the eyepiece of described optical microscope and the object lens.During measurement, with rotational positioning cover fixing (in operation, the rotational positioning cover can be fixed on the object lens of surgical operation microscope), the arch guide rail is rotated around rotating locating sleeve, be aided with optical microscope moving on the arch guide rail, be equivalent to make optical microscope on a sphere, to move; Therefore, at any testee that is positioned at three-dimensional space (extent of disease, damaged body), no matter its position how, by regulating the position of optical microscope, can make the optical axis of optical microscope vertical (straight line is vertical with straight line or straight line is vertical with the plane) with testee, at this moment, on graticule, can directly read the size of testee by the picture of testee, this mode need not be inserted survey instrument in patient's body, and measure accurately, can save operating time greatly, reduce patient's misery, improve the operation quality.
Described Medical Optical Measuring Instrument is characterized in that described optical microscope has one
Shape lens barrel, eyepiece are positioned at this lens barrel upper end, and object lens are positioned at this lens barrel lower end; Two corners at this lens barrel are respectively arranged with forward prism and refracting prisms, and described graticule is positioned at the eyepiece downside.The special shape of lens barrel be convenient to carry out survey measurements in the art, and the setting of forward prism makes the picture of observed testee conform to the real space position of testee.
Described Medical Optical Measuring Instrument is characterized in that the limbus that distributes on the described graticule.When reading, the picture of testee is transferred to the center of limbus, be convenient to reading.
Described Medical Optical Measuring Instrument is characterized in that described optical microscope is provided with the dog screw of conflict on the arch guide rail.
Described Medical Optical Measuring Instrument is characterized in that described rotational positioning cover is stuck in an end of arch guide rail, which is provided with anchor ear.
Described Medical Optical Measuring Instrument is characterized in that the radius-of-curvature of described arch guide rail equates with the focal length of optical microphotograph endoscope objective lens.Make optical microscope on the arch guide rail when mobile like this, keep the position inconvenience of testee and object lens, be convenient to regulate and operate.
The present invention is simple in structure, and is easy to operate, can directly read the size of testee on graticule by the picture of testee, this mode need not be inserted survey instrument in patient's body, and measures accurately, saves operating time greatly, reduce patient's misery, improve the operation quality.
[description of drawings]
Fig. 1 is a structural representation of the present invention.
Fig. 2 is for reading the synoptic diagram of testee size on graticule.
[embodiment]
Medical Optical Measuring Instrument shown in Figure 1 mainly comprises optical microscope A and arch guide rail B two parts:
Optical microscope A is connected on the arch guide rail B by its mirror holder A8, thereby can slide on radius-of-curvature is 250 millimeters arch guide rail, and by dog screw A7 location; The lens barrel A4 of optical microscope is
Shape, eyepiece A1 is positioned at this lens barrel upper end, and object lens A6 (focal length is 250 millimeters) is positioned at this lens barrel lower end; Two corners at this lens barrel are respectively arranged with forward prism A5 and refracting prisms A3, and graticule A2 is positioned at eyepiece A1 downside.
The dog screw B3 that the right-hand member card of arch guide rail B has rotational positioning cover B1 and conflicts and put in rotational positioning, rotational positioning puts and is provided with anchor ear B2.
During measurement, by anchor ear B2 rotational positioning is overlapped the object lens C that B1 is fixedly connected on surgical operation microscope and goes up (its focal length be 250 millimeters for good, be convenient to make the object focal point of optical microscope to overlap like this with the object focal point of surgical operation microscope, in operation to damaged body or lesion locations on the three-dimensional space position, only need it is adjusted on the focus, can observe and optical microscope measuring by surgical operation microscope simultaneously, even and have some deviations in the practical operation, also be convenient to regulate), spotlight by surgical operation microscope illuminates damaged body D (or lesion locations), regulate the position of optical microscope, make the optical axis of optical microscope vertical with tested damaged body (or lesion locations), by rotating the distance that accurate burnt spiral A9 regulates object lens A6 and damaged body (or lesion locations), damaged body (or lesion locations) is positioned on the focus of object lens, imaging is clear, again by the position of rotational positioning cover B1 adjusting as E, make image position (see Fig. 2 in the center of limbus B2a, promptly the two ends that make picture by range estimation apart from limbus about equally), observe by eyepiece, can on graticule, directly read the size of testee.
