Problems solved by technology

[0012] 1) Since it belongs to the simple judgment of whether the predetermined condition is satisfied, an erroneous judgment occurs (for example, in response to local features (angles, etc.), it cannot be acquired in the overall shape),
[0013] 2) Since it is judged based on the instantaneous shape at a time, the ability to withstand external disturbances is poor
[0014] In addition, in the conventional example of Japanese Patent Application Laid-Open No. 2004-358095, if the information is observed at the time of analyzing and displaying the ring-shaped situation, the information can be grasped, but since the display is regularly updated, the In the case of missing the timing to observe the vicinity analyzed as a ring, there is a disadvantage of missing this information

Embodiment 1

[0053] Such as figure 1As shown, an electronic endoscope system 1 as an endoscope insertion shape analysis device is composed of an endoscope device 2 , an endoscope insertion shape observation device 3 , and an image processing device 4 .

[0054] The endoscope device 2 is composed of an electronic endoscope 21 , a video processor 22 , a light source device 23 , and an observation monitor 24 .

[0055] The electronic endoscope 21 is configured to emit observation light for illuminating an observation site in the lumen from the distal end of the insertion portion 21a through a light guide (not shown) provided in the insertion portion 21a. The electronic endoscope 21 is provided with an unillustrated electronic imaging device (eg, CCD) at the tip of an elongated insertion portion 21 a inserted into a lumen of a body cavity of a subject. In addition, the electronic endoscope 21 generates and outputs an imaged image signal of an observation site in the lumen when the electronic ...

Embodiment 2

[0133] Since the second embodiment is almost the same as the first embodiment, only the differences will be described, and the same components will be given the same reference numerals and their descriptions will be omitted.

[0134] In this embodiment, the memory 41e is provided with Figure 14 A ring buffer 90 of size eight is shown, for example.

[0135] The data acquisition count Count from the beginning of the check is associated with the insertion shape data, so in this embodiment, by using the remainder of Count / 8 as the storage location of the ring buffer 90, the past N times (wherein, N<8) Storage and retrieval of interpolated shape data. Other structures are the same as in Embodiment 1.

[0136] In this embodiment, a part of the shape analysis processing in step S11 is different from that in Embodiment 1, so the Figure 15 ~ Figure 17 Explain the difference.

[0137] In the shape analysis processing of this embodiment, as Figure 15 and Figure 16 As shown, aft...

Embodiment 3

[0147] Since Example 3 is almost the same as Example 1, only the differences will be described, and the same components will be assigned the same symbols and descriptions will be omitted.

[0148] Such as Figure 19 As shown, the PC 41 of the image processing device 4 of this embodiment has, for example, a third communication port 41d capable of communicating with the image organizing device 100 as an external device.

[0149] The image organizing apparatus 100 is composed of a PC 101 for managing / recording image data, a mouse 102 , a keyboard 103 , and a display 104 connectable to the PC 101 . The PC 101 of the image organizing device 100 has a communication port 101a capable of communicating with the PC 41 of the image processing device 4, a memory 101b, and a recording device 101c.

[0150] Figure 19 It is a processing module representing an insertion shape analysis application 151, an insertion shape data recording application 151a, an insertion shape display applicatio...

Abstract

The invention provides a apparatus for analyzing shape into which endoscope is inserted. An electronic endoscope system as an apparatus for analyzing a shape into which an endoscope is inserted comprises: an electronic endoscope having the insertion part to be inserted into a body cavity; a shape observing device for detecting the shape of the insertion part with the use of a plurality of source coils in the endoscope insertion part, a sense coil unit, and a shape processor, etc.; a display for displaying an endoscope image picked-up by the endoscope and the shape detected by the shape observing device; and a PC for performing the pattern classification of shape data, based on the shape detected by the shape processor on the basis of information which is detected by the shape processor.

Description

technical field [0001] The present invention relates to an endoscope insertion shape analysis device and an endoscope insertion shape analysis system that analyze conditions that hinder the insertion when an endoscope insertion portion is inserted. Background technique [0002] When performing insertion observation with an endoscope, lumens in body cavities of the subject are curved, such as the large intestine and small intestine. Therefore, if it is clarified at what position in the lumen the endoscope insertion portion is inserted and what shape the endoscope insertion portion has, the operability of the endoscope observation treatment will be improved. [0003] Therefore, conventionally, an endoscope shape detecting device that detects the insertion shape of the endoscope using a source coil or the like has been proposed as a device capable of knowing the state of bending or the like when the endoscope is inserted. [0004] Here, when observing a subject with an endosco...
