Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of hysteroscopes, in particular to a leak-proof hysteroscope. Background Art
[0002] Hysteroscope is a medical device widely used in the field of gynecology for observing, diagnosing and treating diseases in the uterine cavity. After the injection of uterine distension fluid during surgery, it is often difficult to effectively prevent the fluid from leaking from the uterine cavity. This not only affects the clarity of the surgical field of view, but may also increase the risk and complexity of the operation.
[0003] In order to solve the above problems, some hysteroscopic devices use blocking devices to try to prevent the leakage of distending fluid. These blocking devices usually need to be manually installed before the hysteroscope enters the uterine cavity. The operation is cumbersome and it is difficult to ensure the tightness and accuracy of the blocking. Since the shape and size of the uterine cavity vary from person to person, the existing blocking devices are often difficult to adapt to the size and position of the uterine cavity of different patients, resulting in poor blocking effect. For this reason, we propose a leak-proof hysteroscope. Utility Model Content
[0004] The purpose of the utility model is to provide a leak-proof hysteroscope to solve the problems raised by the above-mentioned background technology.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a leak-proof hysteroscope, comprising a hysteroscope body, a sleeve is slidably mounted on the outside of the hysteroscope body, a bucket-shaped plugging head is fixedly mounted on the outside of the sleeve, a vertical plate is fixedly mounted on the outside of the sleeve, a sliding rod is slidably mounted inside the vertical plate, and an annular contact plate for converging the bucket-shaped plugging head is mounted on one end of the sliding rod;
[0006] An adjusting component for driving the sliding rod to move is arranged on one side of the vertical plate, and a moving component for driving the sleeve to move is fixedly installed on the outer side of the hysteroscope body.
[0007] Preferably, the bucket-shaped plugging head is made of elastic silicone material.
[0008] Preferably, the adjustment assembly includes a first threaded rod, which is rotatably mounted on one side of the vertical plate, the first threaded rod has threads passing through the sliding rod, and a first knob is fixedly mounted on one end of the first threaded rod.
[0009] Preferably, the moving component includes a mounting plate, a sliding groove is provided on one side of the mounting plate, a slider is slidably installed inside the sliding groove, a support plate is hinged on one side of the slider, one end of the support plate is hinged on the outside of the sleeve, and a threaded part for driving the slider to move is provided inside the sliding groove.
[0010] Preferably, the threaded member is specifically a second threaded rod, and the second threaded rod is rotatably installed inside the sliding groove.
[0011] Preferably, a second knob is fixedly mounted on one end of the second threaded rod.
[0012] Compared with the prior art, the beneficial effects of the utility model are:
[0013] 1. When using the leak-proof hysteroscope, the front end of the hysteroscope body is inserted into the uterine cavity for detection. After the uterine distension fluid is injected, the first knob is turned to drive the first threaded rod to rotate, thereby driving the sliding rod to drive the annular resistance plate to move in the opposite direction. The annular resistance plate moves in the direction close to the vertical plate, thereby reducing the contraction of the bucket-shaped plugging head. The bucket-shaped plugging head expands outward under the action of its own elastic force, and finally blocks the uterine cavity opening, thereby preventing the uterine distension fluid from leaking out.
[0014] 2. The leak-proof hysteroscope drives the second threaded rod to rotate by turning the second knob, so that the slider moves inside the slide groove. The slider drives the sleeve to move outside the hysteroscope body through the support plate, thereby changing the position of the bucket-shaped plugging head. After the hysteroscope body is inserted into the appropriate position in the uterine cavity, the bucket-shaped plugging head can just block the uterine cavity opening, making the hysteroscope more suitable for different patients.

[0020] Embodiment 1
[0021] Please refer to Figure 1-3 As shown, the utility model provides a leak-proof hysteroscope, including a hysteroscope body 1, a sleeve 2 is slidably mounted on the outside of the hysteroscope body 1, a bucket-shaped plugging head 3 is fixedly mounted on the outside of the sleeve 2, a vertical plate 4 is fixedly mounted on the outside of the sleeve 2, a sliding rod 5 is slidably installed inside the vertical plate 4, and an annular contact plate 6 for converging the bucket-shaped plugging head 3 is installed at one end of the sliding rod 5;
[0022] An adjusting component for driving the sliding rod 5 to move is disposed on one side of the vertical plate 4 , and a moving component for driving the sleeve 2 to move is fixedly installed on the outer side of the hysteroscope body 1 .
[0023] Specifically, the moving component can drive the sleeve 2 to move, change the relative position of the bucket-shaped sealing head 3 and the hysteroscope body 1, and control the expansion and contraction of the bucket-shaped sealing head 3 by adjusting the component, so as to facilitate the expansion of the bucket-shaped sealing head 3 after it is sent into the uterine cavity, thereby reducing patient discomfort.
[0024] Wherein: the bucket-shaped plugging head 3 is made of elastic silicone material, so that it has a certain elasticity.
[0025] Wherein: the adjustment component includes a first threaded rod 7, the first threaded rod 7 is rotatably installed on one side of the vertical plate 4, the first threaded rod 7 threads through the sliding rod 5, and a first knob 8 is fixedly installed at one end of the first threaded rod 7. Rotating the first knob 8 drives the first threaded rod 7 to rotate, thereby driving the sliding rod 5 to move, and driving the annular contact plate 6 to move.
[0026] Among them: the moving component includes a mounting plate 9, a slide groove 10 is provided on one side of the mounting plate 9, a slider 11 is slidably installed inside the slide groove 10, a support plate 12 is hinged on one side of the slider 11, one end of the support plate 12 is hinged on the outside of the sleeve 2, a threaded part for driving the slider 11 to move is provided inside the slide groove 10, and the threaded part is specifically a second threaded rod 13, the second threaded rod 13 is rotatably installed inside the slide groove 10, and a second knob 14 is fixedly installed on one end of the second threaded rod 13, and the second threaded rod 13 is driven to rotate by rotating the second knob 14, so that the slider 11 moves inside the slide groove 10, and the slider 11 drives the sleeve 2 to move outside the hysteroscope body 1 through the support plate 12.
[0027] Working principle: The utility model is a leak-proof hysteroscope. Before use, the first knob 8 is turned to drive the first threaded rod 7 to rotate, thereby driving the sliding rod 5 and the annular contact plate 6 to move. The annular contact plate 6 converges the bucket-shaped plugging head 3, so that the opening range of the bucket-shaped plugging head 3 is small, which is convenient for reducing the patient's discomfort during insertion. When in use, the front end of the hysteroscope body 1 is inserted into the uterine cavity for detection. After the uterine distension fluid is injected, the first knob 8 is turned to drive the first threaded rod 7 to rotate, thereby driving the sliding rod 5 to drive the annular contact plate 6 to move in the opposite direction. The annular contact plate 6 moves in the direction close to the vertical plate 4, thereby reducing the convergence of the bucket-shaped plugging head 3. The bucket-shaped plugging head 3 expands outward under the action of its own elastic force, and finally blocks the uterine cavity opening, thereby preventing the leakage of uterine distension fluid;
[0028] The second threaded rod 13 is rotated by rotating the second knob 14, so that the slider 11 moves inside the slide groove 10. The slider 11 drives the sleeve 2 to move outside the hysteroscope body 1 through the support plate 12, thereby changing the position of the bucket-shaped sealing head 3, so that after the hysteroscope body 1 is inserted into the appropriate position in the uterine cavity, the bucket-shaped sealing head 3 can just block the uterine cavity opening.
