[0030] The structure of the existing camera mainly consists of an endoscope, a zoom lens, a camera body, a lens module, and a camera cable. In the existing camera, during the assembly and use processes, the camera cable rotates within the camera body, increasing the assembly difficulty. Moreover, there are problems such as the core of the cable being easily broken during assembly and affecting the service life of the camera cable. In view of this, the present invention provides a sealing and anti-rotation device for an endoscope camera cable to solve the problem that the camera cable of the endoscope camera is easily broken due to torsion during assembly. Please refer to Figures 1 to 3 , which is an embodiment of the sealing and anti-rotation device for an endoscope camera cable provided by the present invention.

[0031] Please refer to Figure 1 and Figure 2 , a sealing and anti-rotation device 100 for an endoscope camera cable, includes a mounting base 1, a locking member 12, and a movable member 2. A first channel 11 is provided on the mounting base 1, and the first channel 11 penetrates through the mounting base 1. The first channel 11 is used for the endoscope camera cable 11a to pass through; the locking member 12 is fixedly installed on the mounting base 1, and the locking member 12 is used to fix the endoscope camera cable 11a within the first channel 11; the movable member 2 is detachably installed on the mounting base 1. The movable member 2 has a movable stroke installed on the mounting base 1 in the front-rear direction. During its installation process, the movable member 2 abuts against the locking member 12 to drive the locking member 12 to fix the endoscope camera cable 11a within the first channel 11.

[0032] The sealing and anti-rotation device 100 for an endoscope camera cable includes the locking member 12 and the movable member 2. The locking member 12 is fixedly installed on the mounting base 1, and the locking member 12 is used to fix the endoscope camera cable 11a within the first channel 11. The movable member 2 is detachably installed with the mounting base 1. The movable member 2 is movably installed on the mounting base 1 in the front-rear direction. During the installation process of the movable member 2, the movable member 2 abuts against the locking member 12, and the movable member 2 continuously transmits the extrusion force during installation along the radial direction of the first channel 11 to the locking member 12. The locking member 12 fixes the endoscope camera cable 11a within the first channel 11 through the extrusion force. With such a setting, it is not necessary to additionally install a locking device, and it can be achieved only through the interference fit of the locking member 12 and the movable member 2 on the mounting base 1. The structure is simple and easy to implement, and at the same time, it is convenient for disassembly, assembly, and maintenance.

[0033] It should be noted that in this embodiment, the movable member 2 can be an annular component sleeved and installed on the mounting base 1, or can be a plurality of individual components arranged along the circumference of the first channel 11. Correspondingly, the movable member 2 can also be an annular component, or can be a plurality of individual movable members arranged corresponding to the positions of the plurality of locking members 12, and are installed separately, so as to be adjusted according to the actual situation of different camera cables. The present invention does not limit the specific forms of the locking member 12 and the movable member 2, as long as an interference fit can be achieved to transfer pressure and fix the endoscope camera cable 11a.

[0034] Furthermore, the movable member 2 is sleeved with the mounting base 1, and a second channel is provided on the movable member 2 for the endoscope camera cable 11a to pass through. With such a setting, the installation of the movable member 2 can be more convenient. The diameter of the second channel and the first channel 11 can be the same, or the diameter of the second channel can be smaller than that of the first channel 11, which can facilitate the arrangement and restraint of the cable of the endoscope camera and is convenient for the installation and adjustment of the subsequent structure.

[0035] Furthermore, one of the movable member 2 and the mounting base 1 is provided with an internal thread, and the other is provided with an external thread, and the internal thread and the external thread cooperate to install the movable member 2 on the mounting base 1.

[0036] In this embodiment, the sleeving method of the movable member 2 and the mounting base 1 can be through the sleeving of the internal thread and the external thread. Using this matching method, the movable member 2 can be rotatably installed, and it is possible to better judge the situation where the cable is fixed by the resistance generated during rotation, avoiding the locking member 12 failing to stop the rotation of the endoscope camera cable 11a due to being too loose during installation, and at the same time avoiding damaging the endoscope camera cable 11a due to being too tight during installation. In order to ensure the adjustment range, the number of threads provided on the mounting base 1 needs to be not less than the number of threads on the movable member 2.

[0037] Furthermore, one of the movable member 2 and the mounting base 1 is provided with a protrusion, and the other is provided with a groove, and the protrusion and the groove cooperate to install the movable member 2 on the mounting base 1.

[0038] The present invention does not limit the specific sleeving method of the movable member 2 and the mounting base 1. The threaded sleeving method can facilitate the adjustment of the tightness during cooperation, and the method of snap-fitting the protrusion and the groove can make the cooperation more stable. The snap-fitting method of setting the protrusion and the groove is more convenient during installation and disassembly, and at the same time is convenient for corresponding adjustment according to the shape of the locking member 12, and is not easy to fall off after installation, and can achieve a better fixing effect.

[0039] Please refer to Figure 2 , an installation part is provided on the mounting base 1, and a cooperating part is provided on the locking member 12. When the locking member 12 is fixedly installed on the mounting base 1, the installation part is adapted to the cooperating part.

[0040] The locking member 12 is fixedly installed in the mounting base 1. In order to prevent the locking member 12 from rotating during the installation of the endoscope camera or following the rotation of the endoscope camera, which may cause damage to the endoscope camera by the locking member 12 itself, it is necessary to fixedly install the locking member 12 on the mounting base 1. Therefore, an installation part is provided on the mounting base 1, and a cooperating part is provided on the locking member 12, so that the installation part and the cooperating part are adapted to fixedly install the locking member 12. In the present invention, the specific forms and cooperation methods of the installation part and the cooperating part are not limited. It can be abutting, clamping, etc., as long as it can fixedly install the locking member 12 on the mounting base 1 and prevent the rotation of the cable 11a of the endoscope camera.

[0041] Please refer to Figure 2 and Figure 3 , specifically, the installation part is a card slot 13, the card slot 13 is at least partially recessed in a direction away from the first channel 11, and a convex block is formed on the locking member 12 corresponding to the recessed part of the card slot 13, and the convex block forms the cooperating part.

[0042] In this embodiment, the installation part is a card slot 13, the card slot 13 is at least partially recessed in a direction away from the first channel 11 to form a T-shaped surface, a convex block is formed on the locking member 12 corresponding to the recessed part, and one surface of the convex block abuts against the T-shaped surface to clamp the locking member 12 in the groove. With such a setting, the locking member 12 can be fixedly installed in the mounting base 1, and when the movable member 2 is installed, the convex block abuts against the recessed part, and part of the force can be transmitted to the mounting base 1, making the contact between the mounting base 1 and the locking member 12 closer. Please refer to Figure 3 , the locking member 12 forms convex blocks, and the plurality of convex blocks are arranged at intervals along the circumferential side of the locking member 12. A plurality of card slots 13 are arranged in the mounting base 1 corresponding to the convex blocks for cooperation. The locking member 12 is clamped in the card slot 13 so that the locking member 12 will not rotate in the mounting base 1 after installation.

[0043] Please refer to Figure 2 , the endoscope camera anti-rotation device further includes an intermediate member 3, and the intermediate member 3 is used to be arranged between the locking member 12 and the first channel 11 to buffer the movement of the locking member 12 close to the first channel 11.

[0044] In the present invention, the anti-rotation of the endoscope camera cable 11a is mainly achieved by interference fit and anti-rotation through extrusion. In this process, it is relatively easy to damage the endoscope camera cable 11a, which will reduce the service life of the endoscope camera cable 11a. The provision of the intermediate member 3 can not only play a buffering role but also play a role in sealing and waterproofing. The intermediate member 3 can fill the gap between the locking member 12 and the endoscope camera cable 11a, so that moisture or other substances cannot enter, achieving the effect of sealing and waterproofing. Specifically, the intermediate member 3 can extend radially away from the first channel 11 along the rear end of the first channel 11 and be connected to the inner wall of the mounting seat 1 to achieve a better sealing effect.

[0045] Specifically, the intermediate member 3 includes an intermediate portion provided on one side of the locking member 12 close to the first channel 11; and / or, the intermediate member 3 includes a rubber ring provided on the periphery of the first channel 11 and extending in the front-rear direction.

[0046] In this embodiment, the buffer member can be the intermediate portion provided on the locking member 12. The specific manifestation form can be a buffer belt or a buffer strip, or it can also be a rubber ring provided around the first channel 11. The provision of the buffer strip can reduce costs, and the provision of the rubber ring can achieve a better buffering effect. When the movable member 2 is installed, the extrusion force of the movable member 2 on the locking member 12 is transmitted to the rubber ring, and the rubber ring can fit more tightly with the endoscope camera cable 11a after being extruded. While buffering, the effect of sealing and waterproofing is achieved. In one embodiment, the intermediate portion and the rubber ring can be provided simultaneously.

[0047] Specifically, the material of the intermediate member 3 includes silicone, plastic, and rubber.

[0048] Using materials such as silicone, plastic, and rubber, these materials not only have a large elastic deformation and can withstand a greater extrusion force, but also are relatively soft in texture and will not damage the endoscope camera cable 11a, and at the same time are convenient for sealing.

[0049] The present invention also provides a medical device, and the medical device includes the endoscope camera cable sealing and anti-rotation device 100 described above.

[0050] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. All equivalent structural transformations made under the inventive concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied in other related technical fields, are included in the patent protection scope of the present invention.
