[0034] The following is combined with Figure 1-4 The utility model is described in further detail.

[0035] Embodiment 1, refer to Figure 1-4In this embodiment, in order to solve the problem that the existing airbag is set up to expand the vagina of the parturient for suturing, but the airbag will block the midwife's sight after expansion, thereby making it difficult for the midwife to perform the operation, the utility model discloses a vaginal dilator for suturing deep wounds during childbirth.

[0036] It includes an adjustment component 100, which includes a long frame 101. The long frame 101 is internally slidably connected to two expansion blocks 102. A long groove 103 is opened at the bottom of the long frame 101. The long groove 103 is internally slidably connected to two L-shaped bars 104. The tops of the vertical bars of the two L-shaped bars 104 are fixedly connected to the bottoms of the two expansion blocks 102 respectively.

[0037] A C-shaped groove 101a is provided on the left side of the rear side of the long frame 101, and a C-shaped block 101b is slidably connected inside the C-shaped groove 101a. A second compression spring 101c is fixedly connected to the front side of the vertical block of the C-shaped block 101b. The front end of the second compression spring 101c is fixedly connected to the inside of the vertical groove of the C-shaped groove 101a, and can be moved to the inside of the slot 105c through the C-shaped block 101b, so as to facilitate the fixation of the expansion block 102 whose position adjustment is completed. There are several slots 105c, and several slots 105c are equidistantly arranged in a ring shape on the side of the round block 105b. The interior of one of the slots 105c contacts the side of the upper horizontal block of the C-shaped block 101b. Through the several slots 105c, the two expansion blocks 102 can be moved to different positions through the round rod 105a.

[0038] Two support blocks 107 are fixedly connected to the rear side of the long frame 101, and a movable member 105 is rotatably connected to the opposite side of the two support blocks 107. The movable member 105 includes a round rod 105a, and two thread grooves 105d are provided on the left and right sides of the round rod 105a. The two thread grooves 105d have opposite spiral directions. The two expansion blocks 102 can be driven to close inward or open outward at the same time through the two opposite spiral thread grooves 105d. The left end of the round rod 105a passes through the left side of the horizontal bar of the two L-shaped bars 104 and extends to the left side of the left support block 107.

[0039] The left end of the round rod 105a is fixedly connected with a round block 105b, and a slot 105c is provided on the side of the round block 105b. The movable member 105 can adjust the distance between the two expansion blocks 102, and grooves 106 are provided on both sides of the long frame 101.

[0040] The specific working principle is: first, insert the expansion block 102 into the vagina of the parturient, then move the C-shaped block 101b forward, squeeze the second compression spring 101c, so that the upper horizontal block of the C-shaped block 101b moves out from the inside of the slot 105c, and releases the fixation of the round rod 105a. According to the physical condition of the parturient, the two threaded grooves 105d are driven to rotate by the round rod 105a, so that when the round rod 105a rotates, it drives the two L-shaped strips 104 and the two expansion blocks 102 on its upper side to open to the left and right sides respectively, thereby ensuring that the midwife's vision will not be blocked when using the device, making it more convenient for the midwife to perform surgery.

[0041] Example 2, refer to Figure 1-4 In this embodiment, in order to solve the problem that different body shapes of different parturients are different, which may cause the vaginal dilator to easily deviate after being fixed on the parturient, thereby increasing the pressure on the midwife to perform the operation, based on the same concept as the above-mentioned embodiment 1, the vaginal dilator for suturing deep wounds during childbirth also includes:

[0042] The support assembly 200 includes a connecting plate 201, and the two connecting plates 201 are rotatably connected to the inside of the two grooves 106 respectively. T-shaped grooves 202 are provided on both sides of the upper and lower sides of the connecting plate 201. Four T-shaped grooves 202 are grouped in two and the insides are slidably connected with T-shaped plates 203. The T-shaped plates 203 will not slide out from the inside of the T-shaped grooves 202. The side of the horizontal plate of the T-shaped plate 203 is fixedly connected with a first compression spring 204, and one end of the first compression spring 204 is fixedly connected to the inside of the horizontal groove of the T-shaped groove 202. The side of the vertical plate of the T-shaped plate 203 is fixedly connected with a splint 205, and the cross-section of the splint 205 is arc-shaped, and the arc-shaped splint 205 has a larger contact area with the legs of the parturient.

[0043] The specific working principle is: after the expansion block 102 is moved to the vagina of the parturient, the two connecting plates 201 are rotated to both sides and opened, and fit on the side of the parturient's thigh, and then two T-shaped plates 203 and splints 205 are stretched to the upper and lower sides respectively, and the first compression spring 204 is squeezed to make the splint 205 contact the upper and lower sides of the parturient's thigh, and then the T-shaped plate 203 is relaxed, and the T-shaped plate 203 is reset by the rebound force of the first compression spring 204, so that the splint 205 can fit closely with the parturient's thigh, and at the same time, the friction between the splint 205 and the parturient's leg is increased by the silicone sheet, thereby ensuring that the vaginal dilator will not deviate after fixing the parturient, thereby reducing the surgical suture pressure of the midwife.

[0044] Example 3, refer to Figure 1-4In this embodiment, in order to solve the problem that some existing vaginal dilators have sharp areas, which may cause the parturient to be easily injured during surgery, based on the same concept as the above-mentioned embodiment 1, the vaginal dilator for suturing deep wounds during childbirth also includes:

[0045] The adjustment component 100 includes a long frame 101, and two expansion blocks 102 are slidably connected inside the long frame 101. The side surfaces of the expansion blocks 102 are rounded. When the expansion blocks 102 with rounded corners are moved into the vagina of the parturient, the parturient will not feel discomfort due to the sharpness.

[0046] The specific working principle is: by providing the expansion block 102 with two rounded sides, it can be ensured that the side surface will not hurt the parturient when it contacts the inside of the vagina of the parturient, thereby reducing the possibility of injury to other parts of the vagina of the parturient.

[0047] The above are all preferred embodiments of the present utility model, and are not intended to limit the protection scope of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the protection scope of the present utility model.
