[0024] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0025] Please refer to Figures 1 to 3 As shown, it shows the specific structure of the preferred embodiment of the utility model, which is a universal control device for an endoscope.

[0026] The ball seat 20, the adjustment arm 23 and the operating rod 25 are integrated as a whole, which has better strength, reduces the number of accessories and is easy to assemble. The ball head 11 is directly assembled with the ball seat 20. This structure does not require any extra accessories. The ball head 11 and the base 10 can be directly assembled together, which is easier to assemble.

[0027] The present application provides a universal control device for an endoscope, comprising a base 10, a ball head 11, and a ball seat 20; the ball head 11 is arranged on the base 10; a spherical groove 21 is arranged in the ball seat 20, and a first elastic seam 22 is arranged on the groove wall of the spherical groove 21; an adjustment arm 23 is extended at an equal angle on the outer wall of the ball seat 20; the ball head 11 is movably embedded in the spherical groove 21; a steel wire 27 is arranged in the insertion tube; the first end of the steel wire 27 is connected to the adjustment arm 23; the second end of the steel wire 27 can movably pass through the adjustment hole 13 on the base 10; an operating rod 25 is extended on the outer wall of the ball seat 20. The base 10 and the ball seat 20 can be injection molded, and the ball head 11 is made of metal or plastic material. There are four adjustment arms 23 in this embodiment, and the adjustment arms 23 are distributed at equal angles. The spherical groove 21 and the ball head 11 of this embodiment are assembled together by interference fit. There is a certain friction and damping feeling between the spherical groove 21 and the ball head 11, which makes the operation smoother and has a certain self-stabilizing effect. The outer wall of the ball seat 20 is extended with an operating rod 25 and an adjustment arm 23, which has good integrity, higher strength, reduced number of accessories, and simpler assembly. The first elastic seam 22 has four channels, which are distributed at equal angles on the ball seat 20. The first elastic seam 22 makes the ball seat 20 have a certain elastic deformation, which makes it easier for the ball head 11 to be installed in the spherical groove 21. The ball head 11 is directly and movably embedded in the spherical groove 21 of the ball seat 20. The steel wire 27 is pulled by turning the operating rod 25, so that the camera, tool, etc. inserted into the tube can be rotated in any direction, which is very convenient.

[0028] Preferably, the area of ​​the ball head 11 wrapped by the spherical groove 21 exceeds one-half, and this design prevents the ball head 11 from falling off the spherical groove 21, while the ball head 11 can move flexibly in the spherical groove 21. More specifically, the area of ​​the ball head 11 wrapped by the spherical groove 21 is between one-half and two-thirds, which ensures the wrapping property and allows the ball seat 20 to move flexibly in the ball head 11.

[0029] Preferably, the adjustment arm 23 extends horizontally or obliquely downward from the bottom of the ball seat 20. This design utilizes the principle of lever, and a small force is applied to the operating rod 25, so that the adjustment arm 23 can obtain a large force to pull the steel wire 27, which is more labor-saving to operate. More specifically, the inclination angle A of the adjustment arm 23 is between 5-30°, such as 5°, 10°, 15°, 20°, 30°, etc., which is selected according to specific needs.

[0030] Preferably, a rope end hole 24 is provided at the end of the adjusting arm 23, and a second elastic slit 28 is passed through the hole wall of the rope end hole 24, and the rope end of the steel wire 27 is embedded in the rope end hole 24. The second elastic slit 28 facilitates the installation of the rope end of the steel wire 27 and also facilitates the assembly of the steel wire 27. The steel wire 27 can directly pass through the rope end hole 24, and then the rope end is embedded in the rope end hole 24.

[0031] Preferably, the size of the head end of the operating rod 25 is larger than the size of the end of the operating rod 25, and a positioning notch 26 is provided at the end of the operating rod 25. This design is conducive to enhancing the strength of the operating rod 25 and preventing it from breaking. The positioning notch 26 facilitates the adjustment knob to be directly inserted into the positioning notch 26.

[0032] Preferably, the base 10 and the ball head 11 are fixed by screws or pins, and the screws or pins are inserted into the ball head 11 from the bottom of the base 10. The base 10 and the ball head 11 of this embodiment are fixed by screws. Of course, the base 10 and the ball head 11 can also be snap-connected, threaded, etc. The ball head 11 is made of metal material and has better wear resistance. When the base 10 and the ball head 11 are an integrated structure, the base 10 and the ball head 11 are connected by a vertical rod 12, so that the ball head 11 can be erected to a certain height.

[0033] In summary, the design focus of the utility model is that the ball seat 20, the adjustment arm 23, and the operating rod 25 are an integrated structure, which has better strength and is easy to assemble. The ball head 11 can be directly assembled in the spherical groove 21 in the ball seat 20. This structure reduces accessories, is easier to assemble, and has lower manufacturing costs.

[0034] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
