Embodiment Construction

[0013] The medical optical measuring instrument shown in Figure 1 mainly includes two parts: an optical microscope A and an arched guide rail B:

[0014] The optical microscope A is clamped on the arched guide rail B through its frame A8, so that it can slide on the arched guide rail with a curvature radius of 250 mm, and is positioned by the positioning screw A7; the lens barrel A4 of the optical microscope is The eyepiece A1 is located at the upper end of the lens barrel, the objective lens A6 (with a focal length of 250 mm) is located at the lower end of the lens barrel; the two corners of the lens barrel are respectively provided with a forward prism A5 and a refracting prism A3, and the reticle A2 is located at the eyepiece A1 underside.

[0015] The right end of the arched guide rail B is clamped with a rotating positioning sleeve B1 and a positioning screw B3 that interferes with the rotating positioning sleeve, and the rotating positioning sleeve is provided with a ho...

Abstract

The invention relates to a medical optical gauge which can measure illness variation range, defection body and repairing body of operative surgery, especially to micro operative surgery. It comprises an optical microscope which can moving posited on an arched rail, wherein one end of the said arched rail has rotating stop cover; the reticule is posited between the eye lens and the object lens of microscope.

Description

【Technical field】 [0001] The invention relates to a medical optical measuring instrument, which is an instrument for accurately measuring lesion range, defect body and restoration body in surgery (especially microsurgery). 【Background technique】 [0002] The evaluation of the lesion range, the size of the defect, and the calculation of the size of the prosthesis in traditional surgery mostly rely on simple measuring tools, such as scales, protractors, etc. These measuring tools have a certain volume and length, while microsurgery often does not These tools are allowed to be placed in the patient's body, or cannot be put in for measurement due to the irregular surgical field, so the measurement in the actual operation mainly depends on the operator's experience and subjective estimation. This method of subjective estimation by the operator has a large error. It is difficult to meet the requirements of high-precision surgery; if you want to make a replacement implant to repair...
