Conventionally, in order to know the insertion depth of the insertion section mentioned above,
A scale indicating the distance from the tip is attached to the insertion tube,
I read the numbers on this scale when necessary. However, with this method, the surgeon must read the scale each time he or she wants to know the insertion depth, which is very inconvenient as it takes time and effort to find the scale, and it is very inconvenient for the surgeon to know the insertion depth. When the operator is looking into the eyepiece window of the endoscope, he or she must move his/her body toward the insertion section in order to read the scale, which is very cumbersome and reduces work efficiency. .

In these conventional examples, it is possible to know the insertion depth of the insertion tube, but if the insertion tube rotates (rotates) or twists during insertion, the observation direction of the distal end of the insertion tube may be difficult to observe, especially in a perspective or side view. The viewing type endoscope has the disadvantage that it is not able to quickly observe the target area because it shifts. In addition, when performing medical treatment using a treatment tool such as forceps, if the direction in which the forceps are projected is unclear, there is a risk of damaging the inner wall of the body cavity, making it impossible to perform treatment quickly and in cases where urgency is required. This was particularly problematic. In addition, when it is necessary to always set the insertion tube tip at the same location, such as when periodically observing a target site such as a body cavity to examine changes in a lesion over time, it is necessary to adjust the insertion depth and rotation angle. If there were a means to measure and display it appropriately, it would be easier to set up, but this type of device has not been available until now.

1 It has a holder that holds the insertion section of the endoscope so that it can move back and forth and rotate, and a fixture that fixes the holder to the object to be observed, and the holder moves the insertion section of the endoscope back and forth in the axial direction. a first bearing that is freely supported and has a forward/backward movement amount detection means that detects the amount of movement of the insertion portion in the forward/backward direction; and a first bearing that rotatably supports the first bearing on the outer periphery of the first bearing. The second bearing has a rotation amount detection means for detecting the amount of rotation of the insertion portion through a second bearing, and outputs from each of the detection means according to the amount of movement and rotation in the forward/backward direction are detected in an appropriate forward/backward direction. 1. A positioning device for an endoscope, comprising: a signal conversion means for converting into an amount and a rotation amount signal; and a display means for displaying an insertion depth and a rotational position based on the output from the signal conversion means.
