Scale for measurement under endoscope

Abstract

The invention relates to a scale for measurement under an endoscope. The scale comprises a scale body, a rotating shaft I, a rotating shaft II, an inner core steel wire, an outer sheath pipe, a push handle and a fixed handle; the scale body is movably connected with the outer sheath pipe through the rotating shaft I and movably connected with the inner core steel wire through the rotating shaft II; the inner core steel wire is arranged in the outer sheath pipe and the fixed handle, and the other end of the inner core steel wire is connected with the push handle; the outer sheath pipe and the fixed handle are integrated and provided with water filling holes; the scale body is a cylinder, and the tip is obtuse; the two sides of the bottom of the outer sheath pipe are opened. The scale is thefirst accessory under the endoscope with the scale, lengths, heights and diameters of different types of lesions can be accurately measured, and clinical and scientific research application of the endoscope is facilitated. Accordingly, the scale at the front end of the accessory deforms in the shape of a 90-degree folding knife in a biaxial rotation mode, scale readings can be seen at any anglesconveniently, and by means of the obtuse design of the tip, severe complications generated by the false injury can be effectively reduced.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a scale for measuring under an endoscope. Background technique [0002] In the process of endoscopic diagnosis and treatment, it is often necessary to measure the length or diameter of the lesion, such as the length, height and diameter of different types of lesions such as ulcers, adenomas, polyps, submucosal raised lesions, foreign bodies, stones, and diverticulum. Existing endoscope accessories lack length measurement tools, and can only be estimated under the endoscope or part of the accessories. Due to the differences in field of view and proportions under the endoscope, the measured values ​​cannot be accurately obtained, so there is a certain gap in the diagnosis stage. Subjectivity will lead to different degrees of error in treatment. Clinical and scientific research urgently need a tool accessory that can accurately measure the length of different lesions under the mic...
