[0033] The disclosure below provides many different embodiments or examples for realizing different structures of the embodiments of the present utility model. In order to simplify the disclosure of the embodiments of the present utility model, the components and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the embodiments of the present utility model. In addition, the embodiments of the present utility model can repeat reference numbers and / or reference letters in different examples, and this repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.
[0034] In order to better understand the purpose, structure and function of the utility model, the following is a further detailed description of the airbag type cervical dilator with a protective function of the utility model in conjunction with the accompanying drawings.
[0035] like Figure 1-Figure 8As shown, the utility model is an airbag type cervical dilator with a protective function, comprising an adjusting plate 1, on which two groups of symmetrical through grooves 18 are provided, and dilating forceps 2 are slidably arranged in the two groups of through grooves 18.
[0036] Furthermore, a first adjustment groove 11 is opened at the bottom of the adjustment plate 1, a second adjustment groove 12 is opened on one side of the first adjustment groove 11, and a slider arranged at the lower side of the expansion clamp 2 is slidably connected to the first adjustment groove 11 and the second adjustment groove 12 respectively, to ensure that the expansion clamp 2 can slide stably.
[0037] The slider on the lower side of the expansion forceps 2 is threadedly connected to the bidirectional screw rod 13 rotating in the second adjusting groove 12. The bidirectional screw rod 13 has opposite thread directions on the left and right sides symmetrically with the center. The bidirectional screw rod 13 is rotated to make the two expansion forceps 2 move in opposite directions, thereby achieving the purpose of cervical dilation. A limit sleeve 14 is provided in the middle part of the bidirectional screw rod 13. The limit sleeve 14 limits the distance between the two expansion forceps 2 to prevent the expansion forceps 2 from moving rapidly toward each other and causing damage to the patient.
[0038] Furthermore, a slide groove 22 is provided at one end of the expansion clamp 2, and a plurality of card grooves 23 are provided on the upper wall of the slide groove 22. At the same time, a slide hole 16 is provided on one side of the adjustment plate 1, and a card plate 17 is slidably arranged in the slide hole 16. When the expansion clamp 2 is expanded to a suitable position, the card plate 17 is slid upward into the corresponding card groove 23 so that the card plate 17 is engaged with the card groove 23, thereby improving the stability of the expansion clamp 2.
[0039] Furthermore, a spring 19 is provided in one of the through grooves 18 of the two groups of through grooves 18. The spring 19 is connected to the expansion clamp 2. When the expansion clamp 2 expands, the spring 19 is squeezed. The reaction of the spring 19 causes the expansion clamp 2 to expand slowly, thereby preventing the patient from being injured by too fast expansion.
[0040] In addition, a handle 15 is symmetrically arranged on one side of the adjustment plate 1 , and the handle 15 is convenient for medical personnel to hold the device for use.
[0041] In addition, an inwardly inclined protective plate 21 is provided at one end of the expansion forceps 2. The protective plate 21 has a certain curvature, which is convenient for preferential placement into the cervix, so that the device can safely enter the cervix.
[0042] In order to further prevent the expansion forceps 2 from causing damage to the cervix, a protection mechanism 3 is installed on one side of the expansion forceps 2 . The protection mechanism 3 includes an air bag strip 31 located on one side of the expansion forceps 2 .
[0043] Specifically, a mounting groove 24 is opened on one side of the expansion forceps 2, and a fixing ring 311 is set on one side of the airbag strip 31. The fixing ring 311 can be installed in the mounting groove 24, and the fixing ring 311 is fixed by a fixing rod 25 inserted in the mounting groove 24. The nut 26 is threadedly connected to one end of the fixing rod 25 that passes through the mounting groove 24 and extends out to fix the fixing rod 25, which also facilitates the replacement of the airbag strip 31 to avoid cross infection.
[0044] When the expansion forceps 2 expand, the airbag strip 31 is inflated to form a linkage effect, which saves expansion time. Specifically, an inflation box 33 is arranged between each group of through grooves 18, and the air outlet of the inflation box 33 is connected to the air inlet of the airbag strip 31 through the trachea 32. At the same time, an extrusion plate 37 is slidably arranged in the inflation box 33, and a connecting rod 35 is arranged on one side of the extrusion plate 37. One end of the connecting rod 35 passes through the inflation box 33 and is connected to the expansion forceps 2. The connecting rod 35 is slidably connected to the inflation box 33. When the expansion forceps 2 expands, it moves with the connecting rod 35, so that the connecting rod 35 pushes the extrusion plate 37 to slide in the inflation box 33, thereby squeezing the gas in the inflation box 33 into the trachea 32. When the gas in the trachea 32 enters the airbag strip 31, the expansion degree of the airbag strip 31 is aggravated, so that the expanded airbag strip 31 contacts the inner wall of the cervix to prevent the patient's cervix from being damaged.
[0045] Secondly, a deflation hole 34 is provided on the upper side of the inflation box 33 , and a detachable sealing member 36 is arranged in the deflation hole 34 . The deflation hole 34 is used to deflate the gas in the airbag strip 31 .
[0046] The inner wall of the inflation box 33 and the extrusion plate 37 are connected by a second spring 38. When the extrusion plate 37 slides, the second spring 38 is squeezed, and the second spring 38 can cause the extrusion plate 37 to return to its original position after the power is lost.
[0047] The working principle of an airbag cervical dilator with a protective function is as follows: a protective plate 21 is placed in the cervix, and the bidirectional screw rod 13 is rotated to slide the two dilating clamps 2 in different directions and squeeze the spring 19. The spring 19 forms a resistance to cause the dilating clamp 2 to expand slowly. At the same time, the dilating clamp 2 pushes the connecting rod 35 to move, so that the connecting rod 35 pushes the squeezing plate 37. The squeezing plate 37 squeezes the gas in the inflation box 33 into the airbag strip 31, thereby intensifying the expansion of the airbag strip 31, causing the airbag strip 31 to contact the patient's cervix and reducing damage to the cervix.
[0048] It is understood that the present invention is described by some embodiments, and those skilled in the art are aware that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. In addition, under the teachings of the present invention, these features and embodiments may be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the scope of protection of the present invention.
