Description

Technical Field

[0001] The utility model relates to the field of medical instruments, in particular to a hysteroscope with air bag leakage prevention effect. Background Art

[0002] Hysteroscopy is a minimally invasive gynecological diagnosis and treatment technology. It is a fiber light source endoscope used for examination and treatment in the uterine cavity. When examining and treating the uterine cavity, it can greatly reduce the damage to the patient's vagina and cervix and reduce the pain caused by the treatment. The present solution specifically relates to a hysteroscope with an air bag leak-proof effect. When the existing hysteroscope is perfused with perfusion fluid, there is a lack of corresponding structure to block the vaginal opening. Therefore, the perfusion fluid is easy to flow out from the vaginal opening after perfusion, causing the perfusion fluid to flow out prematurely, reducing the therapeutic effect of the perfusion fluid. Utility Model Content

[0003] The main purpose of the utility model is to provide a hysteroscope with an airbag anti-leakage effect, which can effectively solve the problems in the background technology.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] A hysteroscope with an airbag leak-proof effect comprises a connector, a perfusion liquid outflow outlet is fixedly installed in the center through the top end of the connector, a perfusion liquid inflow inlet is fixedly installed through the back side of the connector near the lower end, a camera system interface is fixedly installed through the back side of the connector near the upper end, a scope sheath is fixedly installed through the front end of the connector, a scope body is installed inside the scope sheath, and a leak-proof component is arranged outside the scope sheath.

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0019] like Figure 1-Figure 4 As shown, a hysteroscope with airbag leak-proof effect comprises a connector 1, a perfusion liquid outlet 2 is fixedly installed at the center of the top of the connector 1, a perfusion liquid inlet 3 is fixedly installed at the lower end of the back side of the connector 1, a camera system interface 4 is installed at the upper end of the back side of the connector 1, a scope sheath 5 is fixedly installed at the front end of the connector 1, a scope body 8 is installed inside the scope sheath 5, and a leak-proof component 6 is arranged outside the scope sheath 5.

[0020] The anti-leakage component 6 includes an elastic airbag 601, and the main viewing surface of the elastic airbag 601 is arranged in a circular ring shape. Four sealing sliding rings 603 are fixedly installed on the inner ring of the elastic airbag 601 near the front and rear ends, and an air nozzle 602 is fixedly installed on the back side of the elastic airbag 601 near the bottom. By setting up the anti-leakage component 6, when the uterine cavity is inspected and treated, it is convenient to block the vaginal opening to prevent the outflow of the perfusion fluid used for treatment.

[0021] The perfusion fluid outlet 2, the perfusion fluid inlet 3 and the scope sheath 5 are all connected to the interior of the connector 1. The external hose is connected to the perfusion fluid inlet 3, and the perfusion fluid used for treatment is poured into the scope sheath 5 through the perfusion fluid inlet 3 and discharged into the uterine cavity through the end.

[0022] The camera system interface 4 is threadedly connected to the connector 1, and the end of the mirror body 8 is hemispherically set. The external display is connected through the camera system interface 4. At the same time, the hemispherical end of the mirror body 8 reduces the damage to the vaginal wall and the cervical wall.

[0023] The connector 1 and the mirror sheath 5 are both fixedly mounted with a limit ring 7 at their bottom ends, and the limit ring 7 is used to limit the position of the external hose.

[0024] The main viewing surface of the sealing slip ring 603 is arranged in a quarter of a circular ring shape, and the inner diameter of the sealing slip ring 603 is equal to the outer diameter of the mirror sheath 5. When the elastic airbag 601 is filled with gas, the four sealing slip rings 603 are spliced ​​together to form a complete circular ring that is slidably connected to the outer ring of the mirror sheath 5, which is convenient for sealing and leak prevention.

[0025] It should be noted that the utility model is a hysteroscope with airbag leak-proof effect. When in use, firstly, the external display is connected through the camera system interface 4, the external hose passes through the limit ring 7 and is connected to the irrigation liquid inlet 3, the inflation tube is connected to the air nozzle 602, and then the speculum is inserted into the patient's vagina and the vaginal wall is opened, and then the cervix is ​​pulled toward the entrance of the vagina, and then the dilator is used to open the cervix, and the sheath 5 in the hysteroscope is inserted into the cervix;

[0026] After the hysteroscope is placed, the handheld connector 1 is slowly pushed forward, and after the leak-proof component 6 is pushed into the vaginal opening, the elastic airbag 601 is inflated through the inflation tube in conjunction with the air nozzle 602. As the gas in the elastic airbag 601 increases, the four sealing slip rings 603 are moved closer to each other and spliced ​​into a complete annular sliding connection on the outside of the scope sheath 5. After that, the inside of the cervix is ​​conveniently viewed through the scope body 8 and displayed on the external display. At the same time, the perfusion fluid used for treatment is conveniently poured into the scope sheath 5 through the external hose in conjunction with the perfusion fluid inlet 3, and then transported to the uterine cavity through the end of the scope sheath 5;

[0027] When perfusing the perfusion liquid, the vaginal opening is blocked by the inflated elastic airbag 601 to prevent the perfusion liquid from leaking out. At the same time, the outer diameter of the elastic airbag 601 is changed by controlling the amount of inflation, so that the size of the elastic airbag 601 can be adjusted according to the size of the vagina. At the same time, when the perfusion liquid overflows from the perfusion liquid outflow outlet 2, it means that the uterine cavity and the vagina are already full of perfusion liquid and it is impossible to continue perfusing. At this time, the perfusion liquid is stopped.

[0028] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model.
