Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a hysteroscope water leakage prevention device. Background Art

[0002] When performing uterine cavity examination or minimally invasive uterine cavity surgery, it is usually necessary to insert a hysteroscope into the uterine cavity and examine the uterine cavity through the hysteroscope; in this process, it is necessary to inject distension fluid made of physiological saline into the uterine cavity to dilate the uterine cavity. After the distension fluid is injected into the uterine cavity, the uterine cavity will still move or shrink slightly, thereby compressing the distension fluid to flow out of the cervix. In order to prevent the uterine cavity fluid from flowing out of the uterine cavity, it is necessary to add a leak-proof device at the cervix.

[0003] For example, Chinese patent CN110613423A discloses a new type of hysteroscope, which is provided with a hollow waterproof cap and a waterproof flap. The waterproof flap is plugged into the waterproof cap, and the outer diameter of the waterproof cap is equal to the inner diameter of the channel body. The waterproof cap and the waterproof flap prevent the outflow of uterine distension fluid.

[0004] However, the device is large in size, difficult to place at the cervix, and can easily cause discomfort during use; at the same time, during testing or surgery, the uterine distension fluid compresses the uterine cavity, which can easily cause discomfort to the patient.

[0005] Based on this, the utility model designs a hysteroscope anti-leakage device to solve the above problem. Utility Model Content

[0032] The terms “left”, “right”, “front”, “back”, “up” and “down” mentioned in the following description are oriented in the viewing direction of the front view.

[0033] Example 1

[0034] Please refer to the instruction manual Figure 1-3 A hysteroscope anti-leakage device comprises a truncated table 1, on which an injection port 7 for injecting uterine distention fluid, a discharge port 4 for discharging uterine distention fluid and an operation hole 2 for accommodating a hysteroscope 3 are provided; the left sides of the discharge port 4 and the injection port 7 are both connected to a pump body through a hose 8; a buffer plugging component 5 is installed inside the truncated table 1, and an anti-leakage component 6 is installed on the left edge of the truncated table 1, and the buffer plugging component 5 is connected to the anti-leakage component 6. A sealing sleeve is installed in the operation hole 2 to prevent liquid from flowing out.

[0035] In this embodiment, when the hysteroscope anti-leakage device is working normally, the truncated table is placed in the patient's cervix, and the buffer sealing component 5 and the anti-leakage component 6 are operated. The discharge port 4 is blocked by the buffer sealing component 5 to prevent the distension fluid from flowing out through the discharge port 4. The outer wall edge of the truncated table 1 is in close contact with the inner wall of the cervix through the anti-leakage component 6 to prevent the distension fluid from flowing out from the edge of the truncated table 1, thereby effectively preventing the distension fluid from flowing out during hysteroscopic detection or surgery, causing the distension time to be prolonged; the patient is examined by the hysteroscope 3 in the operation hole 2 During the operation, uterine distension fluid is injected into the injection port 7 through the hose 8 connected to the injection port 7, thereby expanding the uterine cavity environment for easy inspection; in this process, the uterine cavity is elastically blocked by the buffer blocking component 5, so that when the uterine cavity is inspected or operated on, the micro-movement or contraction of the human uterine cavity is not affected, thereby improving the patient's comfort and not affecting the inspection of medical staff; after the operation is completed, the buffer blocking component 5 and the anti-leakage component 6 are restored, and the buffer blocking component 5 no longer blocks the discharge port 4, so that the uterine distension fluid is discharged through the discharge port 4.

[0036] Example 2

[0037] like Figure 1-5 As shown, as a preferred embodiment of the utility model, the buffer plugging assembly 5 includes an airbag groove 51, an airbag 52, an air delivery hole 53 and an air delivery pipe 54. The airbag groove 51 is opened inside the truncated table 1, and the air delivery hole 53 is opened at the left end of the truncated table 1. The airbag 52 is fixedly installed at the left end of the airbag groove 51, and the air delivery pipe 54 is fixedly installed at the left end of the air delivery hole 53. The airbag 52 is connected with the air delivery pipe 54 through the air delivery hole 53. Among them, the airbag 52 is made of medical siliconized latex.

[0038] The discharge outlet 4 includes a first discharge outlet 41 and a second discharge outlet 42. The first discharge outlet 41 is opened at the left end of the truncated cone 1, and the second discharge outlet 42 is opened at the right end of the truncated cone 1. The first discharge outlet 41 and the second discharge outlet 42 are connected through the airbag groove 51, and the left end of the first discharge outlet 41 is connected to the hose 8.

[0039] In this embodiment, when the discharge port 4 and the buffer plugging assembly 5 work normally, before the uterine distension fluid is injected, the air supply pipe 54 delivers gas to the airbag 52 through the air supply hole 53 to expand the airbag 52; the airbag 52 expands in the airbag groove 51 until the connection between the first discharge port 41 and the second discharge port 42 is blocked; when the uterine distension fluid is injected into the uterine cavity, it flows into the second discharge port 42, and the airbag 52 is expanded between the first discharge port 41 and the second discharge port 42 to prevent the uterine distension fluid from flowing out; at the same time, there is micro-movement and micro-contraction in the human body's uterine cavity. When the uterine cavity is micro-contracted, the uterine distension fluid squeezes the airbag 52, so that the uterine distension fluid filled in the patient's uterine cavity does not affect the micro-contraction of the uterine cavity, thereby reducing the patient's discomfort of distension and pain; after the operation is completed, the gas in the airbag 52 is discharged through the air supply hole 53 and the air supply pipe 54, and the airbag 52 is restored, so that the uterine distension fluid flows from the second discharge port 42 into the airbag groove 51 and then is discharged through the first discharge port 41.

[0040] Example 3

[0041] like Figure 1-5 As shown, as a preferred embodiment of the utility model, the anti-leakage component 6 includes a groove 61, an elastic membrane 62 and a cavity 63. An annular groove 61 is opened on the left circumferential side of the truncated cone 1, and an elastic membrane 62 is fixedly installed in the groove 61. A cavity 63 is formed between the elastic membrane 62 and the groove 61.

[0042] The anti-leakage component 6 further includes a connection hole 64. The connection hole 64 is provided inside the truncated table 1. The cavity 63 is connected to the air delivery hole 53 through the connection hole 64. The elastic membrane 62 is made of medical siliconized latex.

[0043] In this embodiment, when the water leakage prevention component 6 works normally, in the initial state, the surface of the elastic membrane 62 is located in the groove 61, so that it is convenient to place the truncated table 1 into the cervix; when the gas input by the gas pipe 54 flows into the cavity 63 between the elastic membrane 62 and the truncated table 1 through the connecting hole 64, the gas causes the elastic membrane 62 to expand and deform until the surface of the elastic membrane 62 protrudes to the outside of the groove 61, so that the elastic membrane 62 is in close contact with the inner wall of the cervix to prevent the distending fluid from flowing out from the edge of the truncated table 1; after the operation is completed, the gas in the cavity 63 is discharged through the connecting hole 64, the gas delivery hole 53 and the air bag 52, and the elastic membrane 62 is reset at this time, so that it is convenient to remove the truncated table 1 from the cervix.

[0044] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents.
