[0038] The technical scheme in the embodiment will be described clearly and completely in the following by combining with the drawings, obviously, the described embodiment is only a part of embodiment, not all embodiments.

[0039] As Figures 1 to 5As shown, the embodiment provides an operating handle, which includes a ball head shell 10, a first steel wire transmission mechanism 20 and a second steel wire transmission mechanism 30.

[0040] Specifically, the first steel wire transmission mechanism 20 and the second steel wire transmission mechanism 30 are horizontally arranged on the ball head shell 10.

[0041] Specifically, the first steel wire transmission mechanism 20 and the second steel wire transmission mechanism 30 each have an angle handle 21, and the angle handles 21 on the first steel wire transmission mechanism 20 and the second steel wire transmission mechanism 30 are horizontally arranged outside the ball head shell 10.

[0042] The two angle handles 21 are horizontally arranged, which can facilitate the user to operate the two angle handles 21 with one hand, thereby improving the convenience.

[0043] In the embodiment, the angle handle on the first steel wire transmission mechanism 20 and the angle handle on the second steel wire transmission mechanism 30 have a gap therebetween.

[0044] Specifically, the two angle handles 21 are not mirror-symmetrically arranged, one of which adopts a T-shaped structure, and the other adopts an L-shaped structure; as shown in Figure 1 and Figure 2 As shown, the length of the non-rotation shaft side of the angle handle with the T-shaped structure is shorter than that of the angle handle with the L-shaped structure. In some examples, the angle handle with the T-shaped structure is close to the side connection line hole 12 of the ball head shell.

[0045] The design has the following advantages: the endoscope is generally held and operated by the left hand, the left thumb controls the angle handle 21, and the other fingers control the buttons on the operating handle. Due to the different lengths of the non-rotation shaft sides of the two angle handles, the angle handle close to the left hand's volar interosseous muscle has the T-shaped structure and the non-rotation shaft side is shorter, and the angle handle away from the left hand's volar interosseous muscle has the L-shaped structure and the non-rotation shaft side is longer, so that the user can operate more conveniently when controlling the angle handle with one hand, and the probability of misoperation when operating with one hand can be effectively reduced.

[0046] In the embodiment, a connecting column 40 is arranged between the first steel wire transmission mechanism 20 and the second steel wire transmission mechanism 30, and the first steel wire transmission mechanism 20 and the second steel wire transmission mechanism 30 are fixedly connected with the connecting column 40.

[0047] In the embodiment, the first steel wire transmission mechanism 20 and the second steel wire transmission mechanism 30 each include a disc 22, an angle lock upper disc 23, an angle lock lower disc 24, a hub rotation shaft 25, a friction pressure wheel gasket 26, a hub 27, a cam assembly 28, an angle lock handle 29 and a steel wire 31.

[0048] Specifically, the ball head shell 10 has two side covers 11, and the ball head shell 10 is bolted with the side covers 11. The steel wire 31 is arranged on the hub 27.

[0049] Specifically, the first steel wire transmission mechanism 20 and the second steel wire transmission mechanism 30 are fixedly connected with the two side covers 11 of the ball head shell 10 respectively.

[0050] Specifically, the hub 27 and the friction press wheel gasket 26 are connected with the hub rotating shaft 25 through screws, the hub rotating shaft 25 is assembled on the side cover 11. The angle lock upper wheel disc 23 and the angle lock lower wheel disc 24 are installed on the side cover 11 through nuts, the angle lock upper wheel disc 23 and the angle lock lower wheel disc 24 are linked, and the angle lock lower wheel disc 24 is in contact with the friction press wheel gasket 26. The disc 22 is connected with the hub rotating shaft 25 through a nut and limits the cam assembly 28 on the angle lock upper wheel disc 23. The angle lock handle 29 is connected with the cam assembly 28 through screws.

[0051] When the angle lock handle 29 is rotated, the cam assembly 28 is rotated and drives the angle lock upper wheel disc 23, so that the axial distance between the angle lock upper wheel disc 23 and the angle lock lower wheel disc 24 is increased, and the generated pressure acts on the friction press wheel gasket 26, thereby increasing the friction to achieve the function of the angle lock. The angle handle 21 is connected with the hub rotating shaft 25 through screws, and the hub rotating shaft 25 is rotated and drives the hub 27 to realize the function of rotating angle when the angle handle 21 is rotated.

[0052] In some embodiments, the operation handle further comprises a winding wheel set (not shown) for guiding the steel wire 31 of the first steel wire transmission mechanism 20, so that the first steel wire transmission mechanism 20 and the second steel wire transmission mechanism 30 control two degrees of freedom respectively.

[0053] Exemplarily, the first steel wire transmission mechanism 20 controls the left-right direction, and the second steel wire transmission mechanism 30 controls the up-down direction. By controlling the angle handle to rotate the hub rotating shaft to drive the hub, the steel wire attached to the hub is driven, thereby realizing the four-direction angle function.

[0054] The operation handle has four-direction rotation and double-angle lock functions, greatly utilizes the space, and the overall layout is convenient for single-hand operation. The operator can control four directions with one hand, which is convenient for clinical operation and use, and the four directions have angle lock functions, and the user can position to a certain angle without applying external force.

[0055] In addition, the utility model also provides a kind of endoscope, including operation handle in any of the above embodiments.

[0056] Although the embodiments of the present application have been shown and described above, the protection scope of the present application is not limited thereto, and any change or replacement not thought through creative labor should be covered within the protection scope of the present application; unless explicitly stated, any element, action or instruction used in the present application should not be interpreted as critical or necessary.
