Description

Technical Field

[0001] The invention relates to the technical field of gynecological medicine, and in particular to a hysteroscope anti-leakage device for gynecological surgery. Background Art

[0002] In gynecological surgery, hysteroscopic technology is widely used due to its advantages such as minimally invasive and fast recovery. Hysteroscopic surgery uses a hysteroscope to enter the uterus, directly observe the lesions in the uterine cavity, and perform necessary treatment operations at the same time. In order to ensure a clear surgical field of view and smooth operation, it is necessary to inject liquids such as saline into the uterine cavity to expand the uterine cavity and remove blood or tissue fragments. However, the existing gynecological hysteroscopic anti-leakage device has obvious deficiencies in preventing liquid from leaking from the cervical os. This problem not only affects the surgical effect, but may also cause damage to the cervical os, increasing the surgical risk and the incidence of complications.

[0003] The existing anti-leakage device design is usually relatively simple, mainly using a rubber ring or similar structure to seal the cervical opening. This design is difficult to completely seal in actual operation, especially when the hysteroscope position needs to be constantly adjusted or other surgical instruments need to be inserted during the operation, which can easily cause liquid to leak from the cervical opening. Liquid leakage will not only affect the surgical field of view, making it difficult for doctors to accurately determine the location of the lesion, but may also cause contamination of the surgical area and increase the risk of infection. In addition, liquid leakage may also affect other equipment and the floor in the operating room, causing unnecessary trouble.

[0004] Existing anti-leakage devices may cause damage to the cervical os during use. Since these devices usually need to apply a certain amount of pressure to achieve a sealing effect, this pressure may compress the cervical tissue over a long period of time, causing local ischemia, necrosis, or even tearing. For patients with more fragile cervical tissue, the risk of such damage is greater. Damage to the cervical os will not only cause postoperative pain and discomfort to the patient, but may also affect the function of the cervix, such as premature birth or miscarriage during future pregnancies.

[0005] Existing leak-proof devices lack adaptability to individual patient differences. Every woman's cervical opening is different in size, shape, and elasticity, and existing devices are often standardized and cannot be adjusted according to individual circumstances. This means that in some cases, even if doctors try their best to adjust the device to suit the patient's specific situation, it is difficult to avoid problems caused by poor sealing or excessive pressure.

[0006] Therefore, how to provide a method is an urgent problem to be solved by those skilled in the art. Summary of the invention

[0007] One purpose of the present invention is to provide a hysteroscope anti-leakage device for gynecological surgery. The present invention adjusts the inflation degree of the medical latex airbag through an airbag adjustment component to prevent the medical latex airbag from being too large, which may cause mechanical compression on the cervical opening, resulting in tissue damage or tearing; excessive expansion of the medical latex airbag may compress the blood vessels around the cervical opening, causing local blood circulation disorders and affecting the health of the tissue; the airbag adjustment component allows the doctor to appropriately inflate the medical latex airbag according to the actual size and shape of the cervical opening to avoid excessive expansion, gradually inflate or deflate the air in the medical latex airbag, observe the reaction of the cervical opening while inflating, and deflate it when it is too much, to ensure that the medical latex airbag can both play a leak-proof role and not cause damage to the cervical opening.

The airbag adjustment component 5 is used to adjust the amount of gas inside the medical latex airbag 4. The liquid inlet component 6 is fixedly mounted on the end of the tube body 3 away from the medical latex airbag 4. The liquid inlet component 6 is used to inject uterine distension fluid. In order to expand the uterine cavity and make its internal structure more clearly visible, the volume adjustment component 7 is fixedly mounted on the end of the tube body 3 away from the medical latex airbag 4. The volume adjustment component 7 is used to extract uterine distension fluid to avoid excessive expansion of the uterus caused by excessive uterine distension fluid. Excessive expansion of the uterus may cause pain and discomfort to the patient and affect the smooth progress of the examination. An over-expanded uterus may cause mechanical damage to the uterine wall and other surrounding tissues. The locking screw 8 is threaded into the end of the tube body 3 away from the medical latex airbag 4. The locking screw 8 is used to be fastened to the hysteroscope, and the tightening spring 10 is located inside the medical latex airbag 4.
