Description

Technical Field

[0002] The incidence of gynecological diseases in women is high and increasing year by year, so the demand for their diagnosis and treatment is increasing. Hysteroscope is a medical device used to observe and treat diseases inside the female uterus, but the existing rigid hysteroscope structure is not replaceable, which is easy to cause physical damage and infection, and the operation process is complicated. In response to these problems, the study of self-growing soft hysteroscope can significantly reduce the harm to patients during diagnosis and treatment, which is of great significance.

[0003] Self-growing soft hysteroscopic surgical instruments usually have a large volume, so it is impossible to evenly inflate the entire device during the inflation process. Therefore, a special inflation cavity for the self-growing flexible main body film is designed to achieve the self-growth process of the flexible film. The inflation cavity can effectively control the inflation and exhaust process, thereby promoting the gradual expansion and formation of the flexible film, ensuring that it can be safely and effectively used in the treatment of patients during surgical operations. Summary of the invention

[0043] The self-growing flexible main film 1 includes a self-growing flexible primary main film 11 and a self-growing flexible secondary main film 12. The self-growing flexible main film 1 is made of silicone material, and the overall structure is in a secondary growth mode. The diameter of the self-growing flexible primary main film 11 is larger than that of the self-growing flexible secondary main film 12. The self-growing flexible primary main film 11 forms a wide base, and the self-growing flexible secondary main film 12 presents a variable diameter structure.

[0044] The diameter of the self-grown flexible primary main film 11 is relatively large, forming a wide base to provide stable support. The design of this part can increase the strength of the overall film and provide the necessary space for subsequent growth;

[0045] The diameter of the self-grown flexible secondary main body film 12 is small, presenting a variable diameter structure. Such a design not only helps to achieve more flexible shape changes, but also can better adapt to the external environment when the air pressure changes, thereby improving the functionality of the film. Figure 2 As shown;

[0046] The air-filled cavity housing 2 includes a compression nut 21, a top gland 22, a storage housing 23, a quick plug 24, an air pressure sensor 25 and a bottom gland 26;

[0047] The clamping nut 21 is processed with a through hole in the middle; the top pressure cover 22 is a disc-shaped structure, and a processing protrusion is provided on the top pressure cover 22, and the processing protrusion is connected to the self-growing flexible main body film 1, and the self-growing flexible main body film 1 and the processing protrusion are fixed by an iron hoop, and the clamping nut 21 is connected to the processing protrusion by a thread, and a through hole is provided in the center of the processing protrusion;

[0048] The storage housing 23 is a cylindrical structure, and the top of the storage housing 23 is connected with the top gland 22 by bolts to form a closed cavity;

[0049] The side wall of the storage housing 23 is processed with a threaded hole, and the quick plug 24 is connected to the threaded hole through a thread. The quick plug 24 is connected to an external air pump; the external air pump is connected to the quick plug 24 to inflate the cavity;

A large closed cavity is processed at the bottom of the storage shell 23 and inside the bottom gland 26 to facilitate dynamic sealing of the packing; the air pressure sensor 25 is an electronic component, which is arranged on the inner wall of the storage shell 23 and can sense the air pressure and temperature in the cavity, such as Figure 4 As shown;

[0051] A closed cavity is formed at the bottom of the storage housing 23 and inside the bottom pressure cover 26 .

[0052] The sealing member 3 comprises a compression nut sealing packing 31, a top gland O-shaped sealing ring 32, a top gland oil seal packing 33, a bottom gland O-shaped sealing ring 34, a bottom gland graphite packing 35 and a bottom gland cotton packing 36;

[0053] The sealing of the clamping nut 21 is an alcohol liquid sealing to prevent the self-growing flexible film body from falling off and gas leakage. The space formed between the clamping nut 21 and the top gland 22 is filled with a clamping nut sealing filler 31;

[0054] The storage housing 23 is machined with a circle of grooves, the grooves are filled with cotton stuffing, and the stuffing is infiltrated with oil to form a top gland oil seal stuffing 33 to prevent gas from leaking out through the cavity;

[0055] The top gland 22 is machined with a groove for setting a sealing ring, and the top gland O-ring 32 is pressed to further seal the top gland. Figure 4 shown.

[0056] A bottom gland graphite filler 35 is added to the cavity formed between the bottom gland 26 and the storage shell 23 to prevent gas leakage to the side of the cavity. The cavity is filled with cotton soaked in alcohol to form a bottom gland cotton filler 36. The bottom gland cotton filler 36 is pressed tightly until the self-growing flexible secondary main body film 12 can just pass through the center of the filler to achieve dynamic sealing. When the self-growing flexible secondary main body film 12 passes through, it can ensure good air tightness and disinfect the main body at the same time to reduce the risk of infection;

[0057] The bottom gland 26 is machined with a groove for setting a sealing ring, and the bottom gland O-ring 34 is pressed to further seal the bottom gland. Figure 4 shown.

[0061] In the initial state, the self-growing flexible main body film 1 is stored in the inflatable cavity shell 2, and when the inflatable cavity shell 2 is inflated, the self-growing flexible main body film 1 expands and grows. When the flexible film locking mechanism 4 is closed, the self-growing flexible main body film 1 does not grow, and when the flexible film locking mechanism 4 is closed, the self-growing flexible main body film 1 can grow outward normally.

[0062] A rubber pressing component is disposed on the top of the movable pressing plate 45 , which is responsible for pressing the self-growing flexible main body film 1 and locking the self-growing flexible main body film 1 through friction.
