Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a bubble removal device for gynecological hysteroscopic surgery. Background Technology

[0002] In the field of gynecological clinical surgery, hysteroscopic surgery utilizes the combined use of distending fluid and a hysteroscope. The distending fluid fills the uterine cavity, providing a stable and clear surgical field for the hysteroscope, allowing doctors to accurately observe subtle lesions within the uterine cavity, such as endometrial polyps and submucosal fibroids. This enables accurate diagnosis and effective treatment, and has become a key means of diagnosing and treating various intrauterine diseases.

[0003] During hysteroscopic surgery, a small amount of distending fluid is usually introduced into the hysteroscope to expel air. The patient is kept in a head-down, hip-up position, and the hysteroscope is carefully and slowly inserted into the uterine cavity. Then, distending fluid is injected at the required pressure and speed for different media to expand the uterine cavity, making it full and clear, so that subsequent comprehensive observation can be carried out using the hysteroscope, such as the fundus, fallopian tube openings, anterior and posterior walls of the uterine cavity, left and right lateral walls, and cervical canal.

[0004] As distending fluid is continuously injected into the uterine cavity to expand the cavity space, the pressure inside the cavity gradually increases. This expansion causes air bubbles that might have been present in the distending fluid, as well as those that were not completely expelled during injection, to disperse throughout the cavity. These air bubbles not only interfere with the surgeon's view, affecting the observation and assessment of lesions within the uterine cavity and reducing surgical precision, but they can also hinder the surgical procedure itself. For example, air bubbles may adhere to the surface of the hysteroscope lens, causing blurred vision; secondly, air bubbles may accumulate on the anterior wall or fundus of the uterus. Under the high pressure of the distending fluid, these air bubbles may enter the bloodstream through open small blood vessels, causing serious complications such as gas embolism, threatening the patient's life.

[0005] Therefore, the present invention provides a bubble removal device for gynecological hysteroscopic surgery, which reduces the generation of bubbles during hysteroscopic surgery and facilitates the movement, removal, and puncture of bubbles in the distending fluid. Summary of the Invention

[0006] To address the aforementioned problems, this invention provides a bubble removal device for gynecological hysteroscopic surgery, which reduces the generation of bubbles during hysteroscopic surgery and facilitates the movement, removal, and puncture of bubbles in the distending fluid.

[0007] To achieve the above objectives, the technical solution of the present invention is as follows: A bubble removal device for gynecological hysteroscopic surgery includes a hysteroscope body, a working channel connected within the hysteroscope body, an operating port connected within the working channel, and a lens provided at the end of the hysteroscope body away from the operating port; a deformable isolation membrane is covered on the hysteroscope body, and an injection port for injecting distending fluid is fixedly connected at the end of the isolation membrane near the operating port, the injection port communicating with the gap between the isolation membrane and the hysteroscope body, and the injection port rotatingly engaging with the hysteroscope body;

[0008] Between the isolation membrane and the hysteroscope body, there is a puncture mechanism and a sliding disc for puncturing the isolation membrane and air bubbles in the distending fluid. The puncture mechanism is located on the side of the hysteroscope body closer to the lens. The sliding disc slides in conjunction with the hysteroscope body and is equipped with an electrically telescopic rod for adjusting the support length.

[0009] Furthermore, the puncture mechanism includes a fixing ring, which is fixedly connected to the isolation membrane. The fixing ring is sleeved on the hysteroscope body, and a sliding rod is fixedly connected to the fixing ring. An arc-shaped puncture needle is slidably fitted inside the sliding rod.

[0010] A piston is slidably engaged between the puncture needle and the sliding rod. The piston and the sliding rod are slidably engaged, and the end of the sliding rod away from the puncture needle is connected to an injection tube. The end of the injection tube away from the sliding rod is connected to an injection port.

[0011] When the piston is at its maximum range within the sliding rod, the end of the puncture needle furthest from the sliding rod is positioned above the lens; when the piston is at its minimum range within the sliding rod, the puncture needle is positioned inside the sliding rod.

[0012] Furthermore, the sliding rod is arc-shaped, and the puncture needle includes a needle body and a deformable curved part. The curved part slides with the sliding rod, and the end of the curved part away from the needle body is fixedly connected to the piston. The needle body and the sliding rod are in clearance fit.

[0013] Furthermore, the end of the sliding rod closest to the lens points towards the center of the lens, and when the piston is at its maximum range within the sliding rod, the end of the needle body furthest from the sliding rod is located at the center of the lens.

[0014] Furthermore, a threaded channel is provided at the center of the curved section, and a thread is provided on the side of the needle body near the curved section, with the needle body and the curved section being threadedly connected.

[0015] Furthermore, the sliding disc slides in conjunction with the hysteroscope body, and the output end of the electric telescopic rod is hinged with a ball bearing. The electric telescopic rod is also arranged at an angle, with the end of the electric telescopic rod closer to the ball bearing higher than the end of the electric telescopic rod further away from the ball bearing. A pull rope is fixedly connected to the end of the sliding disc near the injection port, and the end of the pull rope further away from the sliding disc slides in conjunction with the injection port.

[0016] Furthermore, the pull rope is located on the side of the sliding disc near the fixed ring. The fixed ring is equipped with a rotating roller for turning the pull rope. The rotating roller is rotatably engaged with the fixed ring, and the end of the pull rope away from the rotating roller is slidably engaged with the injection port.

[0017] Furthermore, a connecting rod is fixedly connected between the fixing ring and the injection port, and the sliding plate slides with the connecting rod. Several auxiliary tubes are connected inside the connecting rod. The auxiliary tubes are fixedly connected to the isolation membrane. One end of the auxiliary tube away from the connecting rod is connected to the isolation membrane, and the other end of the auxiliary tube is connected to the injection port.

[0018] Furthermore, the fixing ring is threaded with several screws, and the end of the screw away from the fixing ring abuts against the hysteroscope body.

[0019] Furthermore, the end of the needle body away from the sliding rod is fixedly connected with radially distributed barbs.

[0020] The above approach has the following beneficial effects:

[0021] 1. In this solution, the hysteroscope body is wrapped with an isolation membrane. The injection port is connected to the gap between the isolation membrane and the hysteroscope body to allow for vacuuming of the gap, reducing the presence of air on the surface of the hysteroscope body. This facilitates the subsequent delivery of distending fluid through the injection port to wrap the lens.

[0022] 2. In this design, the isolation membrane not only forms an isolation membrane on the surface of the hysteroscope body, but also protects the puncture mechanism and sliding disc to reduce direct contact between the puncture mechanism and the sliding disc and the inside of the uterine cavity. This facilitates the placement of the puncture mechanism and sliding disc inside the uterine cavity to remove air bubbles generated in the distension fluid, thus improving ease of use.

[0023] 3. In this method, the integrated isolation membrane is broken by a puncture mechanism, and then distending fluid is injected through the puncture holes on the isolation membrane to expand the uterine cavity. The distending fluid expands along the lens as the center. By using the isolation membrane with negative pressure air removal as the delivery channel, the occurrence of air bubbles generated when the distending fluid comes into contact with air during the delivery of distending fluid through additional pipes is reduced, thereby reducing the generation of air bubbles during hysteroscopic surgery.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0036] The following detailed description illustrates the specific implementation method:

[0037] Example 1:

[0038] As attached Figures 1 to 8 As shown: A hysteroscopic air bubble removal device for gynecological hysteroscopic surgery includes a hysteroscope body 1, a working channel 13 connected inside the hysteroscope body 1, an operation port 11 connected to the working channel 13, and a lens 12 provided at the end of the hysteroscope body 1 away from the operation port 11; a deformable isolation membrane 2 is covered on the hysteroscope body 1, and an injection port 3 for injecting distending fluid is fixedly connected at the end of the isolation membrane 2 near the operation port 11, the injection port 3 communicates with the gap between the isolation membrane 2 and the hysteroscope body 1, and the injection port 3 rotates with the hysteroscope body 1.

[0039] Between the isolation membrane 2 and the hysteroscope body 1, there is a puncture mechanism and a sliding disc 5 for puncturing the isolation membrane 2 and the air bubbles in the distending fluid. The puncture mechanism is located on the side of the hysteroscope body 1 closer to the lens 12. The sliding disc 5 is slidably engaged with the hysteroscope body 1. The sliding disc 5 is equipped with an electric telescopic rod 51 for adjusting the support length.

[0040] The puncture mechanism includes a fixing ring 4, which is fixedly connected to the isolation membrane 2. The fixing ring 4 is sleeved on the hysteroscope body 1. A sliding rod 41 is fixedly connected to the fixing ring 4. An arc-shaped puncture needle 43 is slidably fitted inside the sliding rod 41. A piston 42 is slidably fitted between the puncture needle 43 and the sliding rod 41. The piston 42 is slidably fitted with the sliding rod 41. The end of the sliding rod 41 away from the puncture needle 43 is connected to an injection tube 7. The end of the injection tube 7 away from the sliding rod 41 is connected to an injection port 3.

[0041] When the piston 42 is at its maximum range within the sliding rod 41, the end of the puncture needle 43 away from the sliding rod 41 is positioned above the lens 12; when the piston 42 is at its minimum range within the sliding rod 41, the puncture needle 43 is positioned inside the sliding rod 41.

[0042] The sliding disc 5 is slidably engaged with the hysteroscope body 1. The output end of the electric telescopic rod 51 is hinged with a ball bearing, and the electric telescopic rod 51 is arranged at an angle, with the end of the electric telescopic rod 51 closer to the ball bearing higher than the end of the electric telescopic rod 51 away from the ball bearing. A pull rope is fixedly connected to the end of the sliding disc 5 near the injection port 3, and the end of the pull rope away from the sliding disc 5 is slidably engaged with the injection port 3.

[0043] In another embodiment, the pull rope is also located on the side of the sliding disc 5 near the fixed ring 4. The fixed ring 4 is provided with a rotating roller (not shown in the figure) for turning the pull rope. The rotating roller is rotatably engaged with the fixed ring 4, and the end of the pull rope away from the rotating roller is slidably engaged with the injection port 3.

[0044] The specific implementation process is as follows:

[0045] First, the physician installs the puncture mechanism and sliding disc 5 onto the hysteroscope body 1, then places the isolation membrane 2 onto the hysteroscope body 1, and uses the injection port 3 to create a vacuum inside the isolation membrane 2. The isolation membrane 2 wraps around the hysteroscope body 1, and the injection port 3 connects to the gap between the isolation membrane 2 and the hysteroscope body 1, allowing for vacuuming of the gap and reducing air on the surface of the hysteroscope body 1. This facilitates the subsequent delivery of distending fluid through the injection port 3 to wrap the lens 12.

[0046] Meanwhile, the isolation membrane 2 not only forms an isolation membrane 2 on the surface of the hysteroscope body 1, but also protects the puncture mechanism and the sliding disc 5 to reduce direct contact between the puncture mechanism and the sliding disc 5 and the inside of the uterine cavity, so that the puncture mechanism and the sliding disc 5 can be placed inside the uterine cavity to remove air bubbles generated in the distending fluid, thus improving ease of use.

[0047] During the use of the puncture mechanism, the filling fluid is injected or recovered using the injection tube 7. In this embodiment, the filling fluid is physiological saline, which can be used as a distending fluid. The piston 42 is pushed by the physiological saline to reduce leakage and contamination that may occur during the flow in the injection tube 7. If there is a leakage of physiological saline, the physiological saline, as a liquid that can come into direct contact with the human body, is mixed with the distending fluid, which has little impact on the human body and ensures safety during use.

[0048] During the process of piston 42 pushing puncture needle 43 inside sliding rod 41 to move, the isolation membrane 2 above lens 12 is punctured when puncture needle 43 is fully extended, providing an injection channel for subsequent injection of distending fluid, so as to facilitate subsequent filling of the uterine cavity and ensure a clear surgical field.

[0049] When it is necessary to remove air bubbles around the hysteroscope body 1, the inclined telescopic rod 51 maintains continuous contact between the ball bearing and the isolation membrane 2, thereby reducing the risk of damage to the isolation membrane 2 by the telescopic rod 51. Simultaneously, by varying the extension length of the telescopic rod 51, a barrier layer is formed around the hysteroscope body 1. A pull rope drives the sliding disc 5 to slide on the surface of the hysteroscope body 1, facilitating the removal of air bubbles around the hysteroscope body 1 through the barrier layer formed by the telescopic rod, reducing the amount of air bubbles remaining in the distension fluid. Furthermore, the two ends of the pull rope drive the sliding disc 5 to move back and forth on the hysteroscope body 1, and the length of the output end of the telescopic rod 51 varies, facilitating the reciprocating movement to remove air bubbles near the hysteroscope body 1, improving processing efficiency.

[0050] Example 2:

[0051] The difference from Embodiment 1 is that the sliding rod 41 is arc-shaped, the puncture needle 43 includes a needle body 44 and a deformable curved part 45, the curved part 45 is slidably engaged with the sliding rod 41, the end of the curved part 45 away from the needle body 44 is fixedly connected to the piston 42, and the needle body 44 and the sliding rod 41 are in clearance engagement.

[0052] The specific implementation process is as follows: By disassembling the puncture needle 43 into a curved part 45 and a needle body 44, the curved part 45 is slidably moved inside the sliding rod 41 by the piston 42, thereby changing the direction of movement and puncture position of the rigid needle body 44. When the hysteroscope body 1 is inserted into the uterine cavity, the deformable curved part 45 drives the needle body 44 to be housed inside the sliding rod 41, so that the isolation membrane 2 and the sliding rod 41 block each other. Even when the hysteroscope body 1 uses negative pressure to remove any residual air inside the isolation membrane 2, the supporting effect of the sliding rod 41 is used to reduce the contact between the needle body 44 inside the sliding rod 41 and the isolation membrane 2. Furthermore, the negative pressure environment inside the isolation membrane 2 reduces the generation of air bubbles during the contact process between the distending fluid and the hysteroscope body 1 when the distending fluid is injected into the isolation membrane 2, ensuring the sealing effect of the isolation membrane 2 on the hysteroscope body 1. This allows the distending fluid to fully wrap the hysteroscope, reducing the obstruction of the surgical field of view by residual air bubbles on the lens 12 and the interference caused by air bubbles in the distending fluid.

[0053] During the process of injecting distending fluid to fill the uterine cavity, the deformable curved part 45 pushes the needle body 44 out of the sliding rod 41, so that the needle body 44 inside the sliding rod 41 punctures the isolation membrane 2, providing an injection channel for the injection of distending fluid inside the isolation membrane 2, thus facilitating the full filling of the uterine cavity.

[0054] Example 3:

[0055] The difference from Embodiment 2 is that the end of the sliding rod 41 near the lens 12 points towards the center of the lens 12, and when the piston 42 is at its maximum range within the sliding rod 41, the end of the needle body 44 away from the sliding rod 41 is located at the center of the lens 12. A threaded channel is formed at the center of the curved portion 45, and a thread (not shown) is formed on the side of the needle body 44 near the curved portion 45, connecting the needle body 44 to the curved portion 45. The detachable connection between the needle body 44 and the curved portion 45 facilitates replacement during use on different patients, reducing the risk of cross-infection. The needle body 44, which is frequently in contact with the human body, is disassembled, while the remaining parts are recycled and disinfected, reducing resource waste and economic burden during reuse.

[0056] The specific implementation process is as follows: The sliding rod 41 is positioned so that it points towards the center of the lens 12, ensuring that the needle body 44 is directed towards the side of the lens 12 away from the hysteroscope body 1. This facilitates the needle body 44 to puncture the isolation membrane 2. When the needle body 44 extends out of the sliding rod 41, it remains at the center of the lens 12. This allows for direct observation through the lens 12 during the subsequent movement of the hysteroscope body 1 to puncture the air bubbles inside the distending fluid. This helps determine the contact between the needle body 44 and the air bubbles in the distending fluid, providing a reference for the needle body 44 to puncture the air bubbles in the distending fluid.

[0057] Example 4:

[0058] The difference from Embodiment 3 is that a connecting rod 6 is fixedly connected between the fixing ring 4 and the injection port 3, the sliding disk 5 is slidably engaged with the connecting rod 6, and a plurality of auxiliary tubes 61 are connected inside the connecting rod 6. The auxiliary tubes 61 are fixedly connected to the isolation membrane 2, one end of the auxiliary tube 61 away from the connecting rod 6 is connected to the isolation membrane 2, and the other end of the auxiliary tube 61 is connected to the injection port 3.

[0059] The specific implementation process is as follows: The connecting rod 6 is used to support the fixed ring 4 and the injection port 3, so that the rotation of the injection port 3 can drive the rotation of the fixed ring 4 during use. Based on the restriction of the needle body 44 by the sliding rod 41 on the fixed ring 4, the obstruction direction of the needle body 44 and the sliding rod 41 can be adjusted. In order to reduce the obstruction of specific directions by rotating the fixed ring 4 while keeping the current observation position of the lens 12 unchanged; at the same time, the auxiliary tube 61 on the connecting rod 6 is used to drive the isolation membrane 2 to move as a whole, so that the air bubbles that may be generated in different directions around the isolation membrane 2 can be suctioned through the auxiliary tube 61 connected to the injection port 3, thereby improving the efficiency and speed of air bubble treatment around the isolation membrane 2.

[0060] Example 5:

[0061] The difference from Embodiment 4 is that the fixing ring 4 is threaded with several screws (not shown in the figure), and the end of the screw away from the fixing ring 4 abuts against the hysteroscope body 1.

[0062] The specific implementation process is as follows: The screws on the fixing ring 4 are rotated and adjusted to adjust the support height of the screws on the hysteroscope body 1, so that the fixing ring 4 meets the support and fixation requirements when engaging with hysteroscope bodies 1 of different diameters, thereby improving the adaptability and flexibility of the fixing ring 4 installation.

[0063] Example 6:

[0064] The difference from Example 5 is that the end of the needle body 44 away from the sliding rod 41 is fixedly connected with radially distributed spikes (not shown in the figure).

[0065] The specific implementation process is as follows: Since the distending fluid in the isolation membrane 2 can only be discharged into the uterine cavity through the small hole pierced by the puncture needle 43, when the distending fluid in the isolation membrane 2 flows near the needle body 44, the air bubbles that may exist in the distending fluid are punctured by the dispersing needle to further reduce the residual air bubbles that may exist in the distending fluid entering the uterine cavity, and to ensure the safety of subsequent hysteroscopy.

[0066] Meanwhile, when the hysteroscope body 1 is subsequently used to puncture any air bubbles that may exist inside the uterine cavity, the puncture area is increased by using dispersed needles to improve puncture efficiency and reduce the need for subsequent movement of the hysteroscope body 1.

[0067] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
