The arrangement scheme of the driving member 120 and the connection and matching scheme with the detecting device 110 in this example are not limited, and may be determined according to the actual configuration scheme and the driving requirement of the detecting device 110.
The deformation component 130 in the present device can generate corresponding deformation when being acted by external force. This deformation part 130 sets up with detection device 110 cooperatees, but real-time induction detection device 110 is detecting the resistance that receives when removing to with the deformation that the resistance conversion that detection device received when detecting the removal corresponds.

Preferably, the deformation component 130 may be an elastic deformation structure, and when a resistance force is sensed during the detection movement of the detection device 110, the corresponding elastic deformation is generated simultaneously.
The arrangement scheme of the deformation component 130 and the arrangement scheme of the deformation component and the detection device 110 are not limited in this example, and may be determined according to the actual configuration scheme and the driving requirement of the detection device 110.

In this embodiment, the specific configuration of the change detecting and processing component 140 is not limited, and may be determined according to actual requirements, and only the deformation amount of the deformation component 130 may be accurately acquired and correspondingly quantified.
By way of example, the change detection and processing component 140 may be formed by a combination of a corresponding change detection unit and a processing unit.
Wherein the deformation detecting unit cooperates with the deformation component 130, and can collect and quantify the deformation amount generated by the deformation component 130 in time. The configuration of the change detecting unit is matched with the specific configuration of the deformation member 130, and is not limited herein.
The processing unit can calculate according to the deformation data of the deformation component 130 collected by the change detection unit to form a detection value which can quantitatively evaluate the passing performance of the jaw opening of the endoscope system.

Then, the detection device directly feeds back the received resistance to the deformation component; at the moment, the deformation component synchronously generates corresponding physical deformation change, and the variation of the deformation component changes along with the resistance condition change of the detection device.
Meanwhile, the change detection and processing component in the detection device synchronously detects the deformation quantity of the deformation component in real time, and calculates a detection value capable of quantitatively evaluating the passing performance of the jaw opening of the endoscope system based on the detected deformation quantity.
And finally, displaying the calculated quantitative detection value through a corresponding display component.

In addition, during the whole moving process of the detection device, the safety control part in the device detects the motion situation of the detection device in real time, stops the motion of the instrument when an abnormal state is detected, and gives an abnormal prompt.
According to the scheme of the embodiment, the detection mode of the passage of the jaw opening can realize quantitative and automatic detection, solve the problem of manual touch detection difference, avoid the conditions of missed detection, manual misjudgment and the like, improve the consistency of endoscope products and improve the detection efficiency of the endoscope.
Example 2
As the detection device enters the endoscope clamping channel cavity, when resistance is met, the working current of the driving part for driving the detection device to move can be increased, and simultaneously, the corresponding required working current can also be changed along with the change of the resistance. For example, the internal resistance of the cavity is basically proportional to the working current of the moving part.
Accordingly, the embodiment provides an endoscope clamp passage passability detection method, which is used for synchronously detecting the working current value for driving a detection device to move in real time while driving the detection device to detect and move in the endoscope clamp passage cavity; and further, calculating a detection value capable of quantitatively evaluating the passing performance of the jaw opening of the endoscope system according to the detected working current value.
Accordingly, this example also provides a variety of endoscope channel passability detection devices, which are different from example 1 in the configuration, and which do not require a deformation member, and a change detection and processing member is connected to and disposed in cooperation with a drive member, and which synchronously detect, in real time, a change in the operating current value when the drive member drives a detection device to detect movement, and perform calculation and analysis based on the detected operating current change value to obtain a detection value capable of quantitatively evaluating the passability of the endoscope system channel.
Other constitution schemes are the same as example 1, and are not described in detail here.
According to the embodiment, the first characteristic information generated in the process of detecting the passability of the endoscope clamp channel by the detector is converted into the second characteristic information which can be quantitatively measured; on the basis, a detection value capable of quantitatively evaluating the passing performance of the jaw opening of the endoscope system is obtained by calculation based on the second characteristic information which is quantitatively measured, so that quantitative analysis and judgment are realized, manual touch and experience are checked, the judgment accuracy is improved, and specific data support is provided.
