[0026] The utility model provides Figure 1 - Figure 6 The illustrated embodiment is a destructible four-wing expansion speculum with protective function, which has the functions of four-wing expansion, destructible after use, and smoke exhaust.
[0027] The details are as follows:
[0028] Example 1
[0029] The expansion piece 1 includes a plurality of jaw plates. The number of the jaw plates in the utility model can be set arbitrarily, preferably four jaw plates, which are evenly arranged on the base plate 21. The base plate 21 is provided with four through holes 22. After the jaw plates and the extension rods 23 are fixedly connected, the extension rods 23 are arranged through the through holes 22, and the spacing of the through holes 22 is greater than the width of the extension rods 23, and the swing angle range of the extension rods 23 in the through holes 22 is allowed to be 0°-20°.
[0030] The jaw plate is set as a hollow structure. When the jaw plate is opened, there are several small holes on the inner side surface that are connected to the internal space. The end of the jaw plate located outside the vagina is connected to the external air pump through a hose. The external air pump is electrically connected to an external controller. The external controller is used to control the air pump to start at an appropriate time to use the negative pressure principle to suck out the smoke inside the vagina. When in use, by turning on the air pump, the smoke generated during the operation is sucked into the hose through the small holes and then discharged, thereby achieving the purpose of smoke exhaust.
[0031] The extension rod 23 is flexibly connected to the inner wall of the through hole 22 through the cut-off piece 26. The cut-off piece 26 can serve both the purpose of connection and the purpose of not limiting the rotation angle of the extension rod 23. Furthermore, stripping grooves are provided on both sides of the cut-off piece 26. After use, the entire dilatation speculum is pulled out, and the operator twists the extension rod 23 to apply a shear force to the extension rod 23 to break the cut-off piece 26. When the jaw plate and the base plate 21 are separated, they cannot be used again, achieving the purpose of being destroyed after use.
[0032] Example 2
[0033] On the basis of Example 1, a fastening ring 24 and an adjusting member 25 are additionally provided. The inner wall of the fastening ring 24 is provided with an internal thread, and the outer wall of the base plate 21 is provided with an external thread. The internal and external threads are connected. An adjusting member 25 is fixed on the inner side of the fastening ring 24. The inner wall of the adjusting member 25 is an inclined frustum. When the fastening ring 24 and the base plate 21 are threadedly connected, the gradually advancing fastening ring 24 will cause the end of the extension rod 23 to conflict with the adjusting member 25. At this time, by changing the relative position between the fastening ring 24 and the base plate 21, the degree to which the adjusting member 25 squeezes the extension rod 23 can be controlled, thereby allowing a plurality of jaws to open inside the patient's vagina. Different feeding amounts of the fastening ring 24 can change the opening angle of the jaws.
[0034] Example 3
[0035] On the basis of the embodiment 1, an adjusting member 25, a cutting member 26, a slider 27, a clearance groove 28 and a slide groove 29 are additionally provided. The adjusting member 25 includes a contact end and a connecting end. The slider 27 is fixed on the connecting end. The slide groove 29 is provided on the inner wall of the base plate 21. The slider 27 slides in the slide groove 29. The contact end includes a plurality of guide blocks with one side lower than the other side, preferably a guide block with an arc surface with a height difference. In this embodiment, four guide blocks are preferably provided. The jaw plate is located on the rotation path of the guide block. Because the guide block has an arc surface with a high and low setting, when the guide block rotates, the corresponding jaw plate can be driven to gradually open. A plurality of levers are fixed on the connecting end of the adjusting member 25. A plurality of clearance grooves 28 are provided on the base plate 21. After the lever passes through the clearance groove 28, it is slidably connected to the side wall of the clearance groove 28, and a friction damping is provided between the two. The damping can reduce the probability of each jaw plate being squeezed back by the inner wall of the vagina. The width of the clearance groove 28 is greater than the width of the guide block, so as to make full use of the height difference of the guide block.
[0036] In both Example 2 and Example 3, the adjustment member 25 is designed to retain an operation hole, and the operation hole is located between a number of opened jaws. When the jaws are opened, the operator can insert a number of instruments through the operation hole into the patient's vagina for surgery or examination.
[0037] In the above embodiment, a plurality of stripping grooves are provided on the extension rod 23 along the extension direction of the extension rod 23. By applying shear force to the stripping grooves at appropriate positions, the excess portion of the extension rod 23 is removed, thereby reducing the visual interference of the excess extension rod 23 to the operator.
[0038] The working principle of the utility model is as follows: the adjusting member 25 is used to interfere with the extension rod 23 or the jaw plate to adjust the inclination angle of the jaw plate, the negative pressure principle is used to discharge the smoke generated during the operation, and the cutting member 26 is used to achieve the purpose of being destroyed after use, which greatly improves the practicality of the expansion speculum in the utility model.
[0039] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model should be included in the protection scope of the present utility model.
