detailed description

Below in conjunction with accompanying drawing 1-4, the specific embodiment of the present utility model is described in further detail.

The utility model includes a lower support body 2, the rear end of the lower support body 2 is slidingly connected with a support 1, the upper end of the support 1 is rotatably connected with an upper support body 3, and the right side of the support 1 is provided with a first connecting rod 5, The upper supporting body 3 can move up and down with the turning over of the first connecting rod 5, and the upper supporting body 3 can turn up and down while moving up and down.

After the medical personnel adjust the patient to a suitable examination posture in advance, slowly insert the duckbill-shaped thin plates at the front ends of the upper support body 3 and the lower support body 2 of the device into the patient's vagina, and then the first connecting rod 5 begins to slowly turn upwards, At this time, the left side of the first connecting rod 5 will drive the support 1 to move upwards, and the support 1 will drive the middle part of the upper support body 3 to move the middle part of the upper support body 3 upwards. At the same time, when the first connecting rod 5 turns upwards, the upper support body will The front end of 3 will deviate upward in an arc, and the upper support body 3 and the lower support body 2 will squeeze the inner wall of the patient's vagina together so that a cavity will appear in the patient's vagina. A certain angle is generated, so that the deep part of the patient's vagina is stretched wider, which makes it easier for medical staff to inspect and treat the patient's genitals.

The middle part of the lower support body 2 is threadedly connected with a threaded rod 4 , and the threaded rod 4 is slidably connected with the middle part of the bracket 1 .

The threaded rod 4 and the opening in the middle of the support 1 limit the position of the support 1 sliding up and down on the lower support body 2, so that the movement distance of the support 1 will not be too large, and prevent the patient's genitals from being hurt.

The lower side of the right end of the lower support body 2 is fixedly connected with a fixed body 13, the right side of the fixed body 13 is rotatably connected with a worm wheel 10, the upper end of the worm wheel 10 is engaged with a worm 9, and the worm 9 and the fixed body 13 are rotatably connected.

When the front end of the device is inserted into the patient's vagina and needs to be expanded and adjusted, the worm 9 is rotated, and the worm 9 rotates to drive the worm wheel 10 to rotate.

The rear side of the worm wheel 10 is fixed coaxially with the first connecting rod 5, the rear end of the first connecting rod 5 is coaxially fixed with a first bevel gear 11, and the right end of the first bevel gear 11 is meshed with a second bevel gear 12. The second bevel gear 12 is rotationally connected with the fixed body 13. The right end of the second bevel gear 12 is coaxially fixed with the third connecting rod 8. The upper end of the third connecting rod 8 is hinged with the second connecting rod 7. The second connecting rod The upper end of the rod 7 and the upper support body 3 are hinged to each other.

When the worm gear 10 rotates, it drives the first connecting rod 5 to rotate synchronously. The first bevel gear 11 rotates synchronously with the worm gear 10. The rotation of the first bevel gear 11 drives the second bevel gear 12 to rotate, and the rotation of the second bevel gear 12 drives the third connecting rod. The rods 8 rotate synchronously. At this time, the upper end of the third connecting rod 8 squeezes the lower end of the second connecting rod 7 to make the arc of the second connecting rod 7 shift forward and backward, and the upper end of the second connecting rod 7 drives the rear end of the upper support body 3 The upper and lower circular arcs are offset, so that the front end of the upper support body 3 is offset by the upper and lower arcs.

The lower rear end of the bracket 1 is fixedly connected with a first protrusion 6 , and the first protrusion 6 is slidably connected with the middle part of the first connecting rod 5 .

When the first connecting rod 5 turns upwards, the opening in the middle of the first connecting rod 5 will squeeze the first protrusion 6 to drive the bracket 1 to move up and down.

When the utility model is used, after the medical personnel adjust the patient to a suitable inspection posture in advance, slowly insert the duckbill-shaped thin plates at the front ends of the upper support body 3 and the lower support body 2 of the device into the patient's vagina, and then turn the worm 9, The rotation of the worm 9 drives the rotation of the worm wheel 10, and the rotation of the worm wheel 10 makes the left side of the first connecting rod 5 deviate in an upward circular arc, and the opening in the middle of the first connecting rod 5 will squeeze and drive the first protrusion 6 to move upward, and the second A protrusion 6 drives the support 1 to move the support 1 upwards. The threaded rod 4 and the opening in the middle of the support 1 limit the position of the support 1 sliding up and down, so that the moving distance of the support 1 will not be too large, preventing the patient's genitals from being hurt. The body 3 moves up with the upward movement of the bracket 1. At the same time, the first bevel gear 11 rotates synchronously with the rotation of the worm gear 10. The rotation of the first bevel gear 11 drives the second bevel gear 12 to rotate, and the second bevel gear 12 The rotation drives the third connecting rod 8 to rotate synchronously. At this time, the upper end of the third connecting rod 8 squeezes the lower end of the second connecting rod 7 to make the second connecting rod 7 deviate in front and rear arcs, and the upper end of the second connecting rod 7 drives the upper end The rear end of the support body 3 is offset up and down by an arc, so that the front end of the upper support body 3 is offset by an arc up and down. At this time, as shown in Figure 1, the upper support body 3 and the lower support body 2 squeeze the patient's vaginal wall There is a cavity in the patient's vagina, and the upper support body 3 can form a certain angle with the lower support body 2 when the arc is offset, so that the deep part of the patient's vagina can be stretched wider, so that it is easier for the medical staff to inspect the patient's genitals. For examination and treatment, the deceleration effect of worm gear 10 and worm 9 will make the speed of worm gear 10 slower, so that the speed of expansion will not be too fast, preventing the patient from feeling uncomfortable. Stretching the patient's vagina, the self-locking principle of the worm gear 10 and the worm 9 keeps the device at a suitable support angle, and does not need to be held by the medical staff all the time, which reduces the workload of the medical staff.

The utility model is novel in structure, ingenious in conception, and simple and convenient in operation. Through this design, it effectively solves the problem that when a conventional internal inspection device for obstetrics and gynecology clinically expands and adjusts the vagina by means of screw bolts or pressing handles, the The operation of the screw adjustment method is cumbersome, which increases the workload of the medical staff. It is not easy to control the adjustment force when pressing the handle adjustment method, and it is not easy to control the expansion size according to the needs. Patient inflicting painful injury problems.

Finally, it should be noted that: the above is only a preferred embodiment of the utility model, and is not intended to limit the utility model, although the utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art , it can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features.
