Problems solved by technology

[0007] However, in the detection using the roller proposed in Patent Document 1, there is a possibility that the roller slides on the outer peripheral surface of the insertion part without rotating or the roller is separated from the outer peripheral surface of the insertion part, resulting in an error in the detection or failure of detection.
On the other hand, in a non-contact detection system using an optical sensor or a magnetic sensor, it is necessary to newly provide a plurality of optical reticles or magnetic reticles in the insertion part, and it is difficult to mount it on an endoscope device that is currently on the market.

[0024] figure 1 It is a perspective view of the insertion portion detection system 1 of the first embodiment.

[0025] The insertion part detection system 1 has: the insertion part detection device 111, which detects the dynamic insertion amount and / or rotation amount of the insertion part; the control part 13, processes and analyzes the data obtained by the insertion part detection device 111; the monitor 14, which displays The result processed by the control part 13, etc.; and the input part 15, and the instruction|indication to the control part 13 is input by an operator. figure 2 An example of the arrangement of the insertion portion detection device 111 of the insertion portion detection system 1 is shown. Such as figure 2 As shown, the insertion portion detection device 111 is installed in the vicinity of the insertion port 22 so that its relative position (interval) with the insertion port 22 of the object 21 to be inserted is constant. For example, in this case, o...

[0059] Figure 7 It is a perspective view of the insertion portion detection device 112 of the second embodiment. This embodiment is configured almost in the same manner as the insertion portion detection system 1 of the first embodiment, and the configuration of the insertion portion detection device 112 is different. Therefore, in the present embodiment, the same reference numerals are given to the same components as those in the first embodiment, and description thereof will be omitted.

[0060] Such as Figure 7 As shown, the insertion portion detection device 112 of the present embodiment includes the sensor unit 32 , the position restricting unit 61 , and the sensor distance maintaining unit 62 . The sensor unit 32 has the same configuration as the sensor unit 31 of the first embodiment. Therefore, the sensor unit 32 has a light source unit 301 , an optical pattern detection unit 302 for imaging the insertion part, and a displacement calculation unit 303 for calculati...

Abstract

An objective of the present invention is to provide a degree of insertion detector device and detector system with which errors in detection of the degree of insertion and / or the degree of rotation are minimized and modifications or additions of new members to an insertion part are made unnecessary. The degree of insertion detector device and degree of insertion detector system comprise: a light source unit which emits a light source light beam toward the outer circumference face of a cylindrical shape of an insertion part which is inserted into a body to be inserted into and becomes a detection subject; an optical pattern detector unit which receives reflected light from the outer circumference face and sequentially acquires a plurality of image data of a prescribed range of the outer circumference face which includes an arbitrary optical pattern such that at least a portion of the optical pattern matches; and a degree of displacement computation unit which detects the matching optical pattern from the plurality of image data and computes the degree of insertion of the insertion part and / or the degree of rotation about the center axis of the cylindrical shape. Thus, the degree of insertion detector device and detector system minimize errors in detection of the degree of insertion and / or the degree of rotation, and modifications or additions of new members to the insertion part are made unnecessary.

Description

technical field [0001] The present invention relates to a detection device and an insertion portion detection system for detecting the insertion amount of a cylindrical insertion portion and the rotation amount around a cylindrical central axis. Background technique [0002] Generally, when inserting an insertion portion of an endoscope apparatus or the like into an object to be inserted, it is necessary to detect an insertion amount. For example, Patent Document 1 proposes a system comprising at least a roller provided on the insertion aid and a sensor for detecting the number of rotations of the roller in order to detect the relative insertion amount of the insertion portion with respect to the insertion aid. [0003] In this configuration, the roller rotates while contacting the outer peripheral surface of the insertion portion, and the insertion amount is calculated by detecting the number of rotations. In addition, as another embodiment, a system is described in which ...
