Problems solved by technology
In complex industrial inspection sites, when the probe of the endoscope is being pulled, it cannot detect the obstacles on the side and front of the probe. If the resistance of the obstacle is judged incorrectly, the pulling force on the probe will be greater than what the pulling wire can bear The limit of the pulling force, so that the pulling line is broken
After the pulling wire is broken, the normal operation of the endoscope is affected, resulting in the scrapping of the endoscope

Embodiment Construction
[0015] In order to make the above objects, features and advantages of the present invention more comprehensible, specific implementations of the present invention will be described in detail below in conjunction with the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. However, the present invention can be implemented in many other ways different from those described here, and those skilled in the art can make similar improvements without departing from the connotation of the present invention, so the present invention is not limited by the specific implementations disclosed below.
[0016] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected ...

The invention provides an endoscope. The endoscope comprises a drive mechanism, an insertion tube, pull wires and a probe, wherein the probe is arranged on the far end of the insertion tube, the pull wires are connected with the drive mechanism and the probe, and the drive mechanism is used for driving the pull wires to move so as to drive the insertion tube to be bent, therefore, the position of the probe is changed. The endoscope comprises a main machine and tension sensors, wherein the main machine is electrically connected with the drive mechanism and the tension sensors, the tension sensors are used for inducing the external force suffered by the pull wires and transmitting induction signals to the main machine, and the main machine controls the drive mechanism according to the induction signals. The arranged tension sensors are used for inducing the external force suffered by the pull wires, so that the real-time stressing condition on the pull wires can be detected, therefore, the situation that when the obstruction suffered by the probe exceeds the ultimate tension of the pull wires, the drive mechanism still pulls the pull wires is avoided, thus the breakage of the pull wires due to overstressing is prevented, and further, the scrap of the endoscope caused as the pull wires are pulled to be broken off is also avoided.
Description
technical field [0001] The invention relates to a detection device, in particular to an endoscope. Background technique [0002] Endoscopes are widely used in medical and industrial fields. In complex industrial inspection sites, when the probe of the endoscope is being pulled, it cannot detect the obstacles on the side and front of the probe. If the resistance of the obstacle is judged incorrectly, the pulling force on the probe will be greater than what the pulling wire can bear The limit of the pulling force, so that the traction line is broken. After the pulling wire is broken, the normal operation of the endoscope is affected, and the endoscope is scrapped. Contents of the invention [0003] Based on this, it is necessary to provide an endoscope that can prevent the pulling wire from being pulled off. [0004] An endoscope comprising a driving mechanism, an intubation tube, a pull wire and a probe, the probe is arranged at the distal end of the intubation tube, the...
