[0003] A patent document with publication number CN200977324Y has appeared in the prior art, which discloses a negative pressure suction device for surgery. The technical solution of the utility model is: a suction bottle and a negative pressure bottle are connected to each other through a connecting tube, a filter is arranged in the suction bottle, one end of a negative pressure suction tube with a switch is inserted into the filter, and the other end is connected to a suction nozzle, and one end of a suction tube connected to a negative pressure machine with a switch is inserted into the negative pressure bottle.

[0031] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0032] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0033] like Figure 1-Figure 6 As shown, the utility model provides a negative pressure suction structure for obstetrics and gynecology surgery, including a suction device 1 and a bottle body limiting clamp 2, the bottle body limiting clamp 2 is installed at the front end of the suction device 1, the number of the bottle body limiting clamps 2 is two, a negative pressure bottle 3 is installed inside the bottle body limiting clamp 2, a sealing cover 4 is installed on the top of the negative pressure bottle 3, an extension ring 5 is installed on the surface of the negative pressure bottle 3, extension blocks 6 are installed on both sides of the extension ring 5, a fixing block 7 is installed on the bottom of the extension block 6, a through groove 8 for use with the fixing block 7 is opened on the surface of the extension ring 5, a control panel 9 is arranged on both sides of the extension ring 5, a fixing rod 10 is installed on the side of the control panel 9 close to the negative pressure bottle 3, and fixing holes 22 for use with the fixing rod 10 are opened on both sides of the extension ring 5.

[0034] The following specifically describes the specific settings and functions of the sealing cover fixing mechanism and the negative pressure bottle clamping mechanism.

[0035] like Figure 2-Figure 4As shown, a noise reduction sleeve 11 is installed on the surface of the fixing rod 10, and the material of the noise reduction sleeve 11 is ethylene-vinyl acetate copolymer. Two first through holes 13 are provided on the surface of the control plate 9, and a guide rod 12 is slidably connected inside the first through hole 13. The end of the guide rod 12 close to the extension ring 5 is fixedly connected to the extension ring 5, and a limiting plate 14 is installed on the end of the guide rod 12 away from the extension ring 5. A spring 15 is installed on the side of the control plate 9 away from the fixing rod 10, and the end of the spring 15 away from the control plate 9 is fixedly connected to the limiting plate 14. The fixing block 7 installed in the through groove 8 is limited by plugging the fixing rod 10 with the inner diameter of the fixing hole 22, which plays a role in stabilizing the position of the sealing cover 4, thereby improving the stability of the connection between the negative pressure bottle 3 and the sealing cover 4, and preventing the sealing cover 4 from detaching during the operation, causing negative pressure. In the case where the pressure inside the pressure bottle 3 is unstable, the noise generated by the fixing rod 10 in the fixing hole 22 can be reduced by setting the noise reduction sleeve 11, thereby reducing the impact on the operation. At the same time, the lower friction resistance will not have a huge impact on the insertion of the fixing rod 10. When the fixing rod 10 is inserted into the inner diameter of the fixing hole 22, the elastic force generated by the spring 15 limits the position of the control plate 9 to prevent the fixing rod 10 from being separated from the fixing hole 22 due to external vibrations and other factors. The guide rod 12 and the first through hole 13 are used in conjunction to guide the movement of the control plate 9, so that the fixing rod 10 can be accurately inserted into the fixing hole 22. The limiting plate 14 limits the range of movement of the control plate 9 to prevent the control plate 9 from being separated from the surface of the guide rod 12 when moving.

[0036] like Figure 5 and Figure 6 As shown, a second through hole 16 is provided on the surface of the bottle body limiting clamp 2, and a control rod 17 is slidably connected inside the second through hole 16. A mounting plate 18 is installed at the end of the control rod 17 close to the negative pressure bottle 3, and a gasket 19 is installed at the end of the mounting plate 18 away from the control rod 17. The material of the gasket 19 is rubber, and a limiting block 20 is installed at the end of the control rod 17 away from the mounting plate 18. A tension spring 21 is sleeved on the surface of the control rod 17, and one end of the tension spring 21 is fixedly connected to the limiting block 20, and the end of the tension spring 21 away from the limiting block 20 is fixedly connected to the bottle body limiting clamp 2. By using the gasket 19 made of rubber, it can While ensuring good quietness, it has good friction with the negative pressure bottle 3, can stably limit the negative pressure bottle 3, and prevent the negative pressure bottle 3 from generating noise due to vibration when in use. At the same time, through the sliding connection between the control rod 17 and the second through hole 16, it is convenient for the user to clamp and fix the negative pressure bottles 3 of different specifications, thereby providing a good surgical environment. The limit block 20 allows the user to better control the pulling of the control rod 17. At the same time, the tension spring 21 can limit the position of the limit block 20, so that the gasket 19 can better clamp and limit the negative pressure bottle 3.

[0037] The overall working principle is that the user installs the sealing cover 4 on the top of the negative pressure bottle 3, and at the same time inserts the fixing block 7 into the inside of the through groove 8, and drives the fixing rod 10 by moving the control plate 9, so that the fixing rod 10 is inserted into the inside of the fixing hole 22, and the fixing block 7 installed in the through groove 8 is limited, which plays a role in stabilizing the position of the sealing cover 4, thereby improving the stability of the connection between the negative pressure bottle 3 and the sealing cover 4. At the same time, through the provision of the noise reduction sleeve 11, the noise generated by the fixing rod 10 in the fixing hole 22 can be reduced, thereby reducing the impact on the operation. When the fixing rod 10 is inserted into the inner diameter of the fixing hole 22, the position of the control plate 9 is limited by the elastic force generated by the spring 15, thereby preventing the control plate 9 from driving the fixing rod 10 due to external vibration and other factors. The control plate 9 is disengaged from the interior of the fixing hole 22, and the guide rod 12 cooperates with the first through hole 13 to guide the movement of the control plate 9, so that the fixing rod 10 can be accurately inserted into the interior of the fixing hole 22. The limiting plate 14 limits the movable range of the control plate 9 to prevent the control plate 9 from disengaging from the surface of the guide rod 12 when moving. When the negative pressure bottle 3 is installed in the interior of the bottle body limiting clamp 2, the control rod 17 is driven to slide in the second through hole 16 by the control limiting block 20, so that the mounting plate 18 drives the gasket 19 to clamp and fix the negative pressure bottle 3, thereby reducing the noise generated when the negative pressure bottle 3 is used. At the same time, the position of the limiting block 20 can be limited by the tension spring 21, so that the gasket 19 can better clamp and limit the negative pressure bottle 3.

[0038] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
