[0036] like Figure 8As shown, the fixed support frame 2 comprises a frame body 201, and the lower end of the frame body 201 is provided with a plurality of support rods 202 located close to the outer edge of the lower end of the frame body 201, and the bottom end of the frame body 201 is fixedly connected with the top end of the fixed part 101. By arranging the support rods 202, the distance between the frame body 201 and the fixed part 101 is increased to provide a movement space for the strip-shaped rod 8. The middle part of the frame body 201 is provided with a through cylindrical hole Ⅱ 203 for the inner rod 3 to pass through, and the outer periphery of the frame body 201 is provided with a plurality of cylindrical sliding grooves 204 which are equally spaced, each of which is in sliding connection with the sliding rod 903, which facilitates the movement of the sliding rod 903 and the cup 9, and also provides a guide for the movement of the cup 9. The lower part of the frame body 201 close to the outer edge is provided with a plurality of uniformly spaced staggered grooves 205, and the strip-shaped rod 8 corresponds to the position of the staggered grooves 205 to avoid interference between the strip-shaped rod 8 and the fixed support frame 2 during movement. Each support rod 202 is staggered with the staggered grooves 205, and the position of each staggered groove 205 is located below each cylindrical sliding groove 204.

[0037] As shown in Figure 9 The inner rod 3 comprises a rod body 301 which passes through the cervical fixation plug 10, the fixed support frame 2, the lifting block 7, the rack 6 and the outer sheath 1 in sequence from top to bottom. The top end of the rod body 301 is provided with a spherical head 302 to facilitate the entry into the cervical orifice and avoid damaging the tissue cells at the cervical orifice position. The lower part of the spherical head 302 is provided with a scale line Ⅰ 303, and the numerical value of the scale line Ⅰ 303 gradually increases from top to bottom. By changing the position of the cervical fixation plug 10, the position can be determined according to the measured values of the depth of the uterus and the depth of the vagina.

[0038] As shown in Figure 2 The middle part of the rack 6 is provided with a through cylindrical hole for the inner rod 3 to pass through, and the cylindrical hole allows the inner rod 3 to pass through without affecting the lifting movement of the rack 6 itself.

[0039] As shown in Figure 11 The lifting block 7 comprises a lifting block body 701, and the middle part of the lifting block body 701 is provided with a through cylindrical hole Ⅲ 702 for the inner rod 3 to pass through. The cylindrical hole Ⅲ 702 facilitates the lifting movement guided by the inner rod 3 while allowing the inner rod 3 to pass through. The outer periphery of the lifting block body 701 is provided with a plurality of uniformly spaced connecting frames Ⅰ 703, and the connecting frames Ⅰ 703 are rotatably connected with the first end of the strip-shaped rod 8 through connecting rods to drive the cup 9 to move.

[0040] As shown in Figure 12As shown, the cup 9 includes a cup body 901, which is arranged as an arc-shaped plate. A plurality of cup bodies 901 can form a cup-shaped uterine cup, which is convenient for guiding the location of the vault.

The sliding rod 903 is provided with evenly spaced scale lines II 904, the values of which gradually increase from the root to the tip. By observing the scale lines II 904, it is convenient to determine the cup diameter of the uterine cup formed by a plurality of cups 9. The lower part of the cup body 901 is provided with a connecting frame II 905, which is rotatably connected to the second end of the strip-shaped rod 8 through a connecting rod, so that the cup body 901 moves under the driving of the strip-shaped rod 8, thereby changing the cup diameter. The outer edge of the cup body 901 is arranged as a circular arc surface to avoid scratching the vaginal tissue when entering the vagina.

[0041] As shown in Figures 2-5 The cervical fixation plug 10 is conical, and the outer edge of the cervical fixation plug 10 is provided with a circular arc surface to facilitate insertion into the cervical orifice. The middle part of the cervical fixation plug 10 is provided with a cylindrical hole for the inner rod 3 to pass through. The rear end of the conical surface of the cervical fixation plug 10 and the inside of the cylindrical hole both have high friction. The circular arc surface has high friction, which can ensure that the cervical fixation plug 10 will not easily fall off after being inserted into the cervical orifice. The cylindrical hole has high friction, which can prevent the cervical fixation plug 10 from moving randomly on the inner rod 3. When the cervical fixation plug 10 needs to change position, a relatively large force is required to push the cervical fixation plug 10 to move on the inner rod 3, so that it rises or falls.

[0042] The upper part of the T-shaped clamping block 11 is "T"-shaped, and the lower end of the "T"-shaped front side is provided with a cylindrical clamping block. The size of the cylindrical clamping block is the same as that of the cylindrical clamping groove 304, and the two can be clamped together. The "T"-shaped design allows the T-shaped clamping block 11 to be clamped inside the T-shaped slot 109 to avoid loosening. The cylindrical clamping block and the cylindrical clamping groove 304 are clamped together, which can fix the inner rod 3.

[0043] In use of the device, first determine the cervical depth, vaginal depth and cervical diameter of the patient, slide the T-shaped clamping block 11 backward, make the cylindrical clamping block of the T-shaped clamping block 11 away from the cylindrical clamping groove 304, move the inner rod 3 up and down, observe the scale value of the scale line I 303 at the position contacted with the top end of the fixed support frame 2, make it equal to the sum of the vaginal depth and the cervical depth, then push the T-shaped clamping block 11 forward, make the cylindrical clamping block of the T-shaped clamping block 11 clamped with the corresponding cylindrical clamping groove 304, so as to realize the fixation of the inner rod 3, move the cervical fixation plug 10 up and down with force, observe the scale value of the scale line I 303 at the position contacted with the top end of the cervical fixation plug 10, make it equal to the value of the cervical depth, pull the knob 4 outward, make the knob clamping block 403 away from the clamping groove 107, rotate the knob 4, when the cylindrical gear 5 is rotated clockwise by the knob 4, the rack 6 moves downward, drives the lifting block 7 to descend, so that the plurality of cup 9 moves inward, the cup diameter decreases, when the cylindrical gear 5 is rotated counterclockwise by the knob 4, the rack 6 moves upward, drives the lifting block 7 to ascend, so that the plurality of cup 9 moves outward, the cup diameter increases, observe the value of the scale line II 904, when the value of the scale line II 904 is equal to the cervical diameter, stop rotating, at this time, align the knob clamping block 403 with the corresponding clamping groove 107, push the knob 4 back, the preparation of the device is completed, and the device can be used.
