[0026] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0027] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it constitute a separate or selective embodiment that is mutually exclusive with other embodiments.

[0029] Reference Figures 1 to 5 , which is a first embodiment of the present invention, provides a cervical detection device, including an expansion unit 1, a fixing frame 11, a fixing plate 12 disposed on the fixing frame 11, and an expansion plate 13 rotatably disposed on the top of the fixing frame 11;

[0030] The fixing frame 11 and the fixing plate 12 are connected via an adjustment component 14, and the fixing frame 11 and the expansion plate 13 are angularly limited by a limiting component 15;

[0031] The detection unit 2 includes a fixing seat 21 arranged at the bottom of the inner cavity of the fixing plate 12, a scale groove 22 opened on the surface of the fixing seat 21, a detection tube 23 slidably arranged on the inner wall of the fixing seat 21, and a blocking component 24 arranged on the detection tube 23.

[0032] It should be noted that the side of the fixing frame 11 is fixedly connected to the fixing plate 12 through the adjustment component 14, and the top of the fixing frame is rotatably connected to the expansion plate 13. A limit component 15 is provided between the expansion plate 13 and the fixing frame to fix the opening angle of the expansion plate 13.

[0033] A fixing seat 21 is fixedly connected to the inner cavity of the fixing plate 12 . A scale groove 22 is provided on the surface of the fixing seat 21 . A detection tube 23 is slidably connected to the inner wall of the fixing seat 21 . A blocking assembly 24 is provided on the detection tube 23 .

[0034] During use, the expansion plate 13 and the fixed plate 12 in the closed state are extended into the vagina. After extending a certain distance, the expansion plate 13 is opened by the limiting component 15, and the expansion plate 13 rotates and expands to open the patient's vagina. Then the blocking component 14 is opened, and the blocking component 14 forms a shield in the expansion area, and then the detection tube 23 is pushed into the vagina. When the blocking component 14 contacts the cervix, the value of the scale groove 22 is read to obtain the length of the cervix extended into the expansion range, so as to accurately read the exposed length of the cervix, which is convenient for the surgeon to arrange the incision point.

[0035] In summary, by integrating the expansion and detection functions, the time-consuming traditional instrument switching is eliminated, and the preoperative preparation time is shortened by 62%. The expansion plate 13 increases the vaginal exposure compliance rate to 95%, and reduces the tissue damage rate to 2.3%. In addition, by setting the top of the cervix at the top of the blocking component 14, the exposed length of the cervix in the expansion area read is more accurate.

[0036] like Figure 1 As shown, as an optional embodiment, the adjustment component 14 includes a first threaded column 141 arranged on the outer wall of one side of the fixing plate 12, an adjustment slot 142 opened on the fixing frame 11, and a first knob 143 arranged on the first threaded column 141.

[0037] It should be noted that a first threaded column 141 is fixedly connected to the outer wall of one side of the fixing plate 12, an adjustment slot 142 is opened on the fixing frame 11, a first knob 143 is threadedly connected to the first threaded column 141, and the first threaded column 141 passes through the adjustment slot 142. The height of the fixing plate 12 can be adjusted by loosening the first knob 153.

[0038] like Figure 1As shown, as an optional embodiment: the limiting assembly 15 includes a paddle 151 arranged on the expansion plate 13, a second threaded rod 152 rotatably arranged on the fixing frame 11, a limiting groove 153 opened on the paddle 151, and a second knob 154 arranged on the second threaded rod 152.

[0039] It should be noted that a paddle 151 is fixedly connected to the expansion plate 13, and a second thread groove 152 is rotatably connected to one side of the fixing frame 11. The second thread groove 152 passes through the limiting groove 153, and a second knob 154 is threadedly connected to the second thread groove 152. The opening angle of the expansion plate 13 is adjusted by rotating the second knob 154.

[0040] like Figures 3 to 5 As shown in the figure, as an optional embodiment, the blocking assembly 24 includes an intercepting plate 241 rotatably disposed in the inner cavity of the detection tube 23, a first connecting rope 242 disposed on the upper surface of the intercepting plate 241, an elastic assembly 243 disposed at the other end of the first connecting rope 242, a second connecting rope 244 disposed on the lower surface of the intercepting plate 241, and a bolt 245 disposed at one end of the detection tube 23;

[0041] One end of the first connecting rope 242 extends into the detection tube 23 and passes through the rotation axis of the intercepting plate 241. The second connecting rope 244 passes through the detection tube 23.

[0042] The elastic component 243 includes a slide groove 2431 formed in the inner cavity of the detection tube 23 , a slider 2432 slidably disposed in the slide groove 2431 , and a spring 2433 disposed between the slide groove 2431 and the slider 2432 ;

[0043] One end of the second connecting rope 244 is fixedly connected to a pull ring 2441 .

[0044] It should be noted that the detection tube 23 is rotatably connected to an interception plate 241.
