[0002] During gynecological examinations, a speculum is a commonly used tool, whose main function is to open the vaginal opening.

[0003] Current speculum devices are typically around 26mm wide, while the natural diameter of a woman's vaginal opening is about 10-15mm. Therefore, using current speculum devices can cause pain for women. Furthermore, during the dilation process, the entire duckbill structure of current speculum devices is open, which further widens the vagina and exacerbates the pain. Utility Model Content

[0036] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0037] Example:

[0038] See Figure 1 , Figure 2 and Figure 3This embodiment discloses a painless endoscope, including a support tube 10, a handle 20, a support plate 30, a drive rod 40, and a camera assembly 50. The support tube 10 has a width between 8mm and 15mm, a smooth outer wall, and rounded corners. The support tube 10 has a hollow interior. An arm is fixedly mounted at one end of the support tube 10 and is perpendicular to the arm. Two support plates 30 are mounted at the other end of the support tube 10, with one end of each plate 30 rotatably connected to the end of the support tube 10. The two support plates 30 are respectively mounted on the upper and lower surfaces of the support tube 10, and their rotation axes are parallel to each other.

[0039] A drive rod 40 is installed inside the support tube 10. One end of the drive rod 40 is connected to the two support plates 30, and the other end of the drive rod 40 passes through the end of the support tube 10 where the handle 20 is installed.

[0040] A camera assembly 50 is also provided on one end of the support tube 10 where the support plate 30 is mounted. The camera assembly 50 includes two lenses with their axes perpendicular to each other. One lens has its axis along the length of the support tube 10, and the other lens faces the side of the support tube 10.

[0041] The cable of the camera assembly 50 is located inside the support tube 10 and extends out from the end of the support tube 10.

[0042] In this embodiment, by setting a small-diameter support tube 10, the support tube 10 is prevented from stretching the vagina, thereby avoiding pain.

[0043] During use, the doctor holds the handle 20 and inserts the end of the support tube 10 with the support plate 30 into the vaginal opening, extending the support plate 30 to the cervix. Then, the two support plates 30 are opened by the drive rod 40 mounted on them, and the cervix and vaginal wall are examined through two lenses on the camera assembly 50. During the examination, samples (such as tissue fluid) can be retrieved from the cervix by the continuous opening and closing of the two support plates 30.

[0044] After the inspection is completed, drive the two support plates 30 together by driving the drive rod 40, and then pull out the support tube 10 and the support plate 30 by using the handle 20.

[0045] In one specific embodiment, the endoscope also includes a light source 60, which is disposed at one end of the support tube 10 mounting the support plate 30.

[0046] Since the vagina is in a dark environment, the shape of the internal tissues is difficult to observe clearly during the examination using the camera component 50. Therefore, a light source 60 is set up to provide sufficient light to the inside of the vagina during the observation process, so as to facilitate the doctor's judgment.

[0047] In another specific embodiment:

[0048] The inner wall of the support tube 10 is provided with multiple support members 70, each support member 70 is provided with a through hole. During the installation process, the drive rod 40 is passed through the through holes on all the support members 70 and is slidably mounted on the through holes.

[0049] This technical solution can restrict the movement path of the drive rod 40, so that the drive rod 40 can only reciprocate in the length direction of the support tube 10.

[0050] In another specific embodiment:

[0051] like Figure 3 As shown, the endoscope also includes connecting rods 80 and a push plate 90. The two connecting rods 80 are respectively disposed on the inner sides of the two support plates 30. Specifically, one end of the connecting rod 80 is fixedly disposed on the support plate 30, and the other end extends in an inclined direction to the inner side of the support tube 10, and the two connecting rods 80 are distributed in an X-shaped structure.

[0052] The push plate 90 is mounted on one end of the drive rod 40 and is perpendicular to the drive rod 40. One side of the push rod is connected to the drive rod 40, and the other side of the push plate 90 is slidably connected to the end of the two connecting rods 80 away from the support plate 30.

[0053] Generally, the push plate 90 is provided with a groove for the end of the connecting rod 80 to slide.

[0054] In this embodiment, the push plate 90 is pushed to move within the support tube 10 by the drive rod 40, thereby driving the two connecting rods 80 to move, and then driving the two support plates 30 to open or close by the connecting rods 80.

[0055] Preferably, the push plate 90 is elongated, and its two ends are slidably disposed on the top and bottom of the inner side of the support tube 10, respectively.

[0056] In another specific embodiment:

[0057] like Figure 3As shown, the handle 20 includes a handle 21 and a pressure rod 22. One end of the handle 21 is vertically fixed to the outside of one end of the support tube 10. The middle part of the pressure rod 22 is rotatably connected to the middle part of the handle 21, and one end of the pressure rod 22 is poweredly connected to the end of the drive rod 40, so that the drive rod 40 can be driven to move through the pressure rod 22.

[0058] Specifically, a through groove is provided in the middle of the handle 21, through which the pressure rod 22 passes, and the pressure rod 22 and the handle 21 are rotatably connected at the through groove.

[0059] In one preferred embodiment, the handle 20 further includes a support rod 23, wherein the two ends of the support rod 23 are rotatably connected to the pressure rod 22 and the drive rod 40, respectively, so that the pressure rod 22 can transmit the motion to the drive rod 40 through the support rod 23 during the rotation of the handle 21.

[0060] In another preferred embodiment, the handle 20 further includes a spring 24, with its two ends fixedly disposed between the end of the pressure rod 22 and the end of the support tube 10, and the spring 24 sleeved on the support rod 23. In this technical solution, the spring 24 enables the pressure rod 22 and the handle 21 to maintain a certain opening angle, thereby pulling the drive rod 40 through the support rod 23, and then pulling the connecting rod 80 through the drive rod 40, so that the two support plates 30 maintain a closed structure.

[0061] During use, due to the action of the spring 24, the two support plates 30 will not be opened due to contact with the soft tissue inside the vagina, thus avoiding the problem of injury to the vaginal wall caused by contact with the soft tissue inside the vagina.

[0062] In another specific embodiment:

[0063] The support tube 10 has a circular or elliptical cross-section, and the two support plates 30 are bent towards each other along an arc-shaped radial direction at their ends away from the support tube 10. By setting the support tube 10 to an arc-shaped surface structure and the support plates 30 to an arc-shaped curved structure, damage to the vaginal wall caused by sharp edges can be avoided.

[0064] In another specific embodiment:

[0065] The support tube 10 has a baffle 100 on the inner side of one end of the support plate 30, and a channel for the drive rod 40 to pass through is opened in the middle of the baffle 100. By providing a channel in the support tube 10, it is possible to prevent vaginal fluid from entering the support tube 10.

[0066] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
