The expansion of the four wings is realized by the upper expansion section 111, the lower expansion section 121 and the two side expansion sections 131, so as to obtain an inspection channel that is more convenient for inspection, and the side expansion structure formed by the cooperation of the side expansion section 131, the rotating part 132 and the sliding part 133 is simple , less materials are used, so that the overall cost of the expansion module 1 used as a consumable is lower. Specifically, the sliding portion 133 is integrally formed with the side expansion section 131 . The opposite side of the two side expansion sections 131 is a smooth arc surface, and the end of the side expansion section 131 away from the sliding part 133 is an arc structure, so that the vagina can be prevented from being damaged when the side expansion sections 131 are opened and matched to form an inspection channel.

The limiting arc-shaped end 1331 is the end of the sliding portion 133 with an arc-shaped structure. The setting of the limiting arc-shaped end 1331 facilitates that the sliding portion 133 is more suitable for forming with the side edge of the pressing portion 113 of the upper expansion member 11 . The sliding fit relationship ensures smooth sliding fit. In a specific application, the limiting arc end 1331 is formed by bending and extending the end of the sliding portion 133 toward the inspection port 1121 in an arc shape, and the end is adapted to form a sliding relationship with the pressing portion 113 .

The two limiting parts 114 on the upper expansion part 11 act on the two side expansion parts 13 respectively, so that the side expansion parts 13 can be opened or closed, so that the upper expansion part 11 and the side expansion parts 13 can be realized with a simple structure. The expansion linkage between them has a simple structure and high stability. Specifically, the two limiting portions 114 are disposed along the side of the pressing portion 113 , and the side of the pressing portion 113 here is the side when the pressing portion 113 cooperates with the transition plate 1123 and the two side plates 1124 to form the inspection port 1121 , and the two limiting portions 114 are respectively disposed on the side of the pressing portion 113 facing the connecting plate 1231 , one end of the two limiting portions 114 is close to the opposite inner walls of the two side plates 1124 , and the other ends of the two limiting portions 114 face each other. extend. Preferably, one end of the two limiting portions 114 is integrally connected to the opposite inner walls of the two side plates 1124 respectively, and the other ends of the two limiting portions 114 extend toward each other and face each other. The limiting arc ends 1331 of the two sliding portions 133 are respectively slidably connected to the two limiting portions 114 . When a force is applied to the pressing portion 113 , in the process of driving the upper expanding section 111 and the lower expanding section 121 to open relatively, the pressing portion 113 simultaneously acts on the limiting arc ends of the two sliding portions 133 through the two limiting portions 114 . 1331, so that the two sliding parts 133 slide toward each other on the two limiting parts 114 respectively, thereby driving the two side expansion sections 131 to open relative to each other. The limiting arc-shaped ends 1331 of the two sliding portions 133 slide opposite to each other on the two limiting portions 114 respectively, and the two side expansion sections 131 are relatively closed. The limiting portion 114 in this embodiment can be a slider. Preferably, there is an escape position 1143 between the two limiting portions 114 . By setting the avoidance position 1143 , the end of the accommodating portion 1221 extending between the two mounting plates 1232 can be avoided, and the electrical coupling 43 can also be passed through, so that the structure of the expansion module 1 is more compact. When the holder 411 of the bearing module 4 is clamped on the bearing position 1224, the functional module 3 is located above the limiting portion 114, so that the functional module 3 does not interfere with the limiting portion 114 at a lower position, The position and operation interference between the functional module 3 and the expansion module 1 is avoided, and the vaginal dilator can be used smoothly. The escape position 1143 in this embodiment is specifically a U-shaped notch formed between the two limiting portions 114 . Preferably, the limiting portion 114 is inclined from the outer side of the inspection channel to the inner side of the inspection channel. In this embodiment, the limiting portion 114 is inclined from the outer side of the inspection port 1121 to the inner side of the inspection port 1121 . In this way, through the inclined arrangement of the limiting portion 114 from the outside to the inside, when the pressing portion 113 exerts a force, the two limiting portions 114 act simultaneously on the two during the process of driving the upper expanding section 111 and the lower expanding section 121 to open relative to each other. The sliding action of the limiting arc-shaped ends 1331 of each sliding portion 133 is smoother. In specific applications, the specific inclination angle of the limiting portion 114 can be set according to the actual situation, and the inclination angle of the limiting portion 114 from the outside of the inspection port 1121 to the inside of the inspection port 1121 is within 5 degrees. Preferably, the limiting portion 114 has a first surface 1141 and a second surface 1142, the first surface 1141 intersects the second surface 1142, the second surface 1142 has a first end 11421 and a second end 11422, and the second surface 1142 is formed by the second surface 1142. When one end 11421 extends toward the second end 11422 , the second surface 1142 is gradually approached toward the first surface 1141 . In this embodiment, the first surface 1141 is the side where the limiting portion 114 and the side of the surface of the pressing portion 113 intersect, wherein the surface of the pressing portion 113 is the side of the pressing portion 113 facing away from the downward expansion member 12 , and the second surface 1142 is On the side of the limiting portion 114 that intersects with the first surface 1141 , the second surface 1142 approximately extends along the length direction of the limiting portion 114 . The second surface 1142 is in sliding contact with the limiting arc end 1331 of the sliding portion 133 . In this embodiment, the first end 11421 is the end of the second surface 1142 that is close to the integral connection between the limiting portion 114 and the side plate 1124 , and the second end 11422 is the second surface 1142 that is far from the limiting portion 114 and the side plate 1124 The other end of the integral connection. It can be understood that when a force is applied to the pressing portion 113 , the second surface 1142 of the limiting portion 114 is in a limiting arc shape with the sliding portion 133 during the process of driving the upper expanding section 111 and the lower expanding section 121 to open relative to each other. The end 1331 is slidably connected, and the second surface 1142 will continue to act on the limiting arc end 1331 of the sliding portion 133, so that the two side expansion sections 131 are relatively opened to form an inspection channel. During the process of forming the inspection channel , the vagina will involuntarily contract, and reversely act on the upper expansion section 111, the lower expansion section 121 and the two side expansion sections 131, which will cause the side expansion section 131 to reversely act on the two limit arc ends 1331 , so that the two limiting arc ends 1331 have a reverse sliding tendency. In practical application, while the second surface 1142 is defined to extend from the first end 11421 to the second end 11422, the second surface 1142 is facing the first end 11422. After the surfaces 1141 are gradually approached, the effect of the second surface 1142 on the limiting arc end 1331 will gradually increase, thereby restricting the reverse sliding tendency of the limiting arc end 1331, and as the second surface 1142 moves toward the first In the process of gradually approaching the surfaces 1141, the limit angle of the second surface 1142 to the limit arc end 1331 will gradually increase, and the restriction on the reverse sliding tendency of the limit arc end 1331 will become stronger and stronger, which can not only make the two The opening process of each side expansion section 131 is smooth, and the limit degree of the limiting arc end 1331 by the limiting portion 114 will be gradually strengthened to resist the reverse effect of vaginal contraction, thereby preventing the limiting arc end 1331 from sliding in the opposite direction. , which ensures that the opening process of the upper expansion section 111 , the lower expansion section 121 and the two side expansion sections 131 is smooth and can be smoothly opened to form an inspection channel.

Embodiment 6

The difference between the vaginal dilator in this embodiment and the second embodiment is that when the upper dilation section 111 and the lower dilation section 121 are in a substantially closed state, the cross-sections of the two are located on the same substantially circular circumference, and are formed by The diameter of the substantially circular shape gradually increases from the direction away from the inspection port 1121 to the direction close to the inspection port 1121 . It can be understood that when the expansion module 1 in a substantially closed state enters the vagina, the vagina needs to undergo a gradual receiving process, otherwise it will cause discomfort to the patient. direction, the diameter of the basic circle gradually increases, so that when the doctor uses the expansion module 1 to enter the vagina, the end of the basic circle with the smaller diameter formed by the cooperation of the upper expansion section 111 and the lower expansion section 121 is the first to enter, Then gradually increase the diameter of the entering basic circle, which will not only reduce the discomfort of the patient, but also make it smoother.

Embodiment 7

The difference between the vaginal dilator in this embodiment and the second embodiment is that when the upper expanding member 11 , the lower expanding member 12 and the two side expanding members 13 are all in the open state, the cross-sections of the four are in the same basic On the circumference of the circle, the diameter of the basic circle gradually decreases from the direction away from the functional end to the direction close to the functional end. In this embodiment, when the upper expansion piece 11 , the lower expansion piece 12 and the two side expansion pieces 13 are all in the open state, that is, when the upper expansion section 111 , the lower expansion section 121 and the two side expansion sections 131 are in the open state , the four form the inspection channel, and the cross-section of the four is located on the same basic circle circumference, which is approximately the same as the inspection channel. From the direction away from the inspection port 1121 to the direction close to the inspection port 1121, the diameter of the basic circle gradually decreases, that is to say, the section of the inspection channel at the vaginal opening is smaller, and as it extends to the depth of the vagina, the diameter of the inspection channel becomes smaller. The cross section gradually increases, so that the inspection space inside the vagina becomes larger, so that it is convenient for doctors to conduct an all-round inspection of the inside of the vagina, avoiding inspection omissions, and enhancing the accuracy of inspection. In addition, the inspection channel formed by the upper expansion section 111, the lower expansion section 121 and the two side expansion sections 131 has a larger end located in the deep vagina, while the inspection channel formed by the four has a smaller end located at the vaginal opening. It also avoids the disengagement of the expansion module 1 during the detection process.

Preferably, the opening direction between the upper expansion section 111 and the lower expansion section 121 is substantially orthogonal to the opening direction between the two side expansion sections 131 . When the upper expansion section 111, the lower expansion section 121 and the two side expansion sections 131 are in an open state, an inspection channel is formed, and the cross-sections of the four are located on the same substantially circular circumference. When the opening direction between the two side expansion sections 131 is in a substantially orthogonal relationship, the opening trajectory between the upper expansion section 111 and the lower expansion section 121 and the opening trajectory between the two side expansion sections 131 are perpendicular to each other, and the four The cross-section of the same basic circle will be located on four equal points of the circumference of the same basic circle, and the interval between the two adjacent equal points is approximately the same. In this way, the dilation effect of the four on the inside of the vagina is the same, and the vagina has the same effect on the four The reverse effect of the four parts is also balanced. At this time, when the four parts are designed, they can be designed into a small width and a long section, which can still ensure the expansion of the vagina and maintain the inspection channel, which can not only reduce the cost, but also reduce the four parts and the vagina. The contact area of the inner wall enables more parts of the inner wall of the vagina to be directly observed, thereby improving the efficiency and accuracy of the inspection of the inner wall of the vagina. In this embodiment, the interval between two adjacent bisector points is approximately the same, which means that the interval between two adjacent bisector points is exactly the same, or there is a slight error in the interval between two adjacent bisector points, But no effect is considered the same.
