Abstract

The invention provides an endoscopic measurement instrument which comprises a control handle. A position-adjustable scale and a slidable handle are mounted on the control handle, a measuring wire driven to move by the slidable handle is connected onto the slidable handle and penetrates a measuring tube, a measuring head taking the front end of the measuring tube as a measuring starting point is mounted at the front end of the measuring tube, the rear end of the measuring tube is connected with the control handle, the initial position of the front end of the slidable handle is set at a 0 scale line of the scale, and the measuring head contacts with the measuring tube at the moment. The moving distance of the measuring head is equal to that of the slidable handle, the moving distance of the slidable handle can be directly read from the scale, the size of a focus can be obtained, the endoscopic measurement instrument is quite convenient to operate and large in space, the scale is arranged outside a body, and the minimum scale value of the scale can be accurate to reach 0.1mm, so that the accurate size of the focus can be obtained.

Description

technical field

[0001] The invention belongs to the field of medical instruments, in particular to an endoscope measuring instrument. Background technique

[0002] In the past, endoscopists used to compare the lesion with the outer diameter of the endoscope used and the diameter of the instrument used at that time, estimate the proportional relationship between the lesion and the control object, and obtain the approximate size of the lesion;

[0003] There are also doctors who measure the size of the lesion according to the scale of the endoscope itself. When measuring, the endoscope needs to be pushed back and forth and repeated measurements to get the estimate of the lesion. Because the scale of the endoscope is relatively large and the endoscope Stretching and compressing the digestive tract when pushing and pulling causes large measurement errors.

[0004] There are also some instruments with scales, and the size of the lesion can be directly observed through the endosc...
