Detailed Description
The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that some, but not all embodiments of the application are described. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.

It is to be understood that the data so used may be interchanged, as appropriate, such that embodiments of the present application may be implemented in sequences other than those illustrated or described herein, and that the objects identified by "first," "second," etc. are generally of a type, and are not limited to the number of objects, such as the first object may be one or more. Furthermore, in the description and claims, "and/or" means at least one of the connected objects, and the character "/", generally means that the associated object is an "or" relationship.
The wire harness support, the cable fixing structure and the endoscope provided by the embodiment of the application are described in detail through specific embodiments and application scenes thereof by combining the attached drawings.
In various embodiments of the present application, "proximal" and "distal" refer to the endoscope and its components in the environment of use, relative to the user's proximal-distal position, wherein the end closer to the user is designated as the "proximal end" and the end farther from the user is designated as the "distal end".
The inventor finds that a cable is connected to the camera module, the proximal end of the cable extends towards the direction close to the operating handle, and a gap between the proximal end of the passive bending tube and the proximal end of the instrument tube penetrates out of the insertion part, enters the operating handle and is connected with a circuit board in the operating handle. When the rotating head is rotated, the passive bending tube and the instrument tube in the insertion part also rotate in a following manner, and as the cable is arranged in a gap between the passive bending tube and the instrument tube and the gap is smaller in size, the cable can be contacted with the passive bending tube or the instrument tube, so that the cable can twist along with the rotation of the instrument tube or the passive bending tube, the cable in the operating handle can be pulled, and pulling stress is generated in the cable, so that the cable is damaged, and obviously, the cable can cause image transmission to be failed, and the observation and diagnosis of a doctor of an operator are influenced.
As shown in fig. 1 to 8, the embodiment of the present application discloses a wire harness support, which is applied to an operation handle 400 of an endoscope, and includes a wire harness member 100, wherein a penetrating channel 110 for penetrating a cable is provided on the wire harness member 100, the penetrating channel 110 includes a redundant section 111, a distal end of the wire harness member 100 is used for being connected to an instrument tube 510 or a passive bending tube 520 of the endoscope, the instrument tube 510 is used for being connected to an operation instrument, or may be used as a suction channel, the passive bending tube 520 is connected to an active bending section of the endoscope, the passive bending tube 520 is capable of being deformed to adapt to a shape of a body cavity, and a proximal end of the wire harness member 100 is used for being connected to a handle housing 410 of the endoscope, and the proximal end of the wire harness member 100 may be directly connected to the handle housing 410 or may be indirectly connected to the handle housing 410 through a part inside the handle housing 410.
Specifically, since the proximal end of the wire harness 100 is fixed to the handle housing 410, the handle housing 410 is a stationary member, and the distal end of the wire harness 100 is fixed to the instrument tube 510 or the passive bending tube 520, the instrument tube 510 or the passive bending tube 520 is rotatable relative to the handle housing 410, and thus the wire harness 100 is torsionally deformed when the instrument tube 510 or the passive bending tube 520 is rotated.
The wire harness 100 is a deformable structure, and the wire harness 100 may be made of an elastic material or a flexible material, and the wire harness 100 can be torsionally deformed following rotation of the instrument tube 510 or the passive bending tube 520, for example. The cross-sectional shape of the wire harness 100 may be circular, square, or the like, and the present application is not limited to the shape thereof. In some embodiments, the outer profile of the cross section of the wire harness 100 includes an arc-shaped section having a penetration passage 110 formed therein, and a flat plate section blocking the penetration passage 110, and a penetration port 130 described below may be provided on the flat plate section. When the wire harness support of the present embodiment is connected to the passive bending tube 520, the flat plate section can be directed to the instrument tube 510, which can make the whole wire harness 100 closer to the instrument tube 510, and further make the cable penetrating into the wire harness 100 closer to the instrument tube 510, so as to prevent the cable penetrating out between the instrument tube 510 and the passive bending tube 520 from being bent outwards, and eliminate the bending position of the cable, and make the cable in a flat state as much as possible.
When the wire harness 100 of the present application is used, the distal end of the wire harness 100 can be connected with the instrument tube 510 or the passive bending tube 520, the proximal end of the wire harness 100 can be connected with the handle housing 410, and the cable can be threaded into the threaded channel 110 on the wire harness 100, since the threaded channel 110 comprises the redundancy section 111, the cable itself can generate redundancy after the cable is threaded into the redundancy section 111, thereby providing a tensile redundancy amount, and even if the wire harness 100 and the cable are twisted along with the rotation of the instrument tube 510 or the passive bending tube 520, the redundant part of the cable can be pulled first, and the pulling stress can not be generated inside the cable, so that the cable is prevented from being damaged, and the normal transmission of images is ensured.
In addition, since the wire harness 100 is inserted into the insertion passage 110, even though the wire harness 100 and the wire harness are twisted and moved relative to the handle housing 410 and the components therein, the wire harness 100 prevents the twisted wire harness from directly contacting the handle housing 410 and the components therein, thereby preventing the wire harness from being worn out, and the wire harness 100 can restrict the wire harness so that the twisted deformation path of the wire harness is consistent with the wire harness 100, that is, so that the twisted deformation path of the wire harness is controllable, which can prevent the wire harnesses from being twisted with each other and prevent the wire harness from being twisted and fatigued due to disorder torsion, which contributes to the life of the extension wire.
