Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a novel dual-channel puncture needle. Background Technology

[0002] Chocolate cysts are a type of endometriosis, a hormone-dependent condition where functional endometrial tissue appears in the ovaries. As the disease progresses, chocolate cysts reduce the number and quality of antral follicles in the ovaries, altering the quality of oocytes and embryos, leading to low fertility or even infertility in women. Due to the high incidence of chocolate cysts, the incidence of pelvic inflammatory disease in women is also increased, causing ovarian cysts to often adhere deep into the pelvic cavity, adhering to surrounding tissues and making them difficult to fully expose or remove from the abdominal cavity. Currently, treatment methods for various cystic diseases include drug therapy, surgery, radiation therapy, and minimally invasive techniques. Drug therapy has a long treatment course and a high recurrence rate; surgery causes severe physical and psychological trauma and is also prone to recurrence; radiation therapy causes significant additional damage and is not easily tolerated by patients.

[0003] Currently, most chocolate cyst removal surgeries are performed laparoscopically, when the cyst is benign. Some cysts are serous or mucinous. Before removal, a loop is typically placed at the intended puncture site, and a long needle connected to a suction tube is inserted to aspirate the contents. After aspiration, the needle is removed, and the cyst wall is lifted using dissecting forceps. The loop is then tightened to prevent leakage of residual fluid from the cyst during removal, which could contaminate the abdominal cavity. During aspiration, the cyst fluid is viscous and has poor flowability, making complete aspiration difficult. Furthermore, the viscous fluid can easily clog the puncture needle, leading to incomplete aspiration and necessitating repeating the puncture procedure.

[0004] Therefore, a novel dual-channel puncture needle is proposed to address the current shortcomings. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the defects of the above-mentioned technology and provide a novel dual-channel puncture needle.

[0006] To solve the above-mentioned technical problems, the technical solution provided by this utility model is a novel dual-channel puncture needle: including a puncture needle body, a negative pressure suction tube, a connector, and a flushing tube;

[0007] The puncture needle body is a hollow cylindrical structure. One end of the puncture needle body is provided with a needle tip. A needle core is provided inside the puncture needle body along its axial direction to divide the puncture needle body into two channels. The negative pressure suction tube and the flushing tube are both connected to the connector. The connector is connected to the end of the puncture needle body and connects the negative pressure suction tube and the flushing tube to the corresponding channels. A plug connected to the negative pressure suction device is connected to the negative pressure suction tube.

[0008] It also includes a vacuum conduit, which is connected to the plug.

[0009] As an improvement, the cross-sectional area of ​​the channel connected to the negative pressure suction tube is larger than the cross-sectional area of ​​the channel connected to the flushing tube.

[0010] As an improvement, both the negative pressure suction tube and the flushing tube are soft conduits.

[0011] The advantages of this utility model compared with the prior art are as follows:

[0012] 1. By combining the dual-channel puncture needle body with the negative pressure aspiration tube and the irrigation tube, the negative pressure aspiration tube can be connected to the aspirator to achieve negative pressure aspiration of cyst fluid. At the same time, the irrigation tube can be used to inject water into the cyst. This facilitates the aspiration of cyst fluid by the negative pressure aspiration tube and prevents blockage of the puncture needle body.

[0013] 2. The puncture needle has a simple structure and is easy to use. It can quickly extract cyst fluid of different viscosity and reduce the probability of the needle body cavity being blocked. At the same time, it can improve the unblocking effect of the needle body cavity and ensure that the cyst fluid can be smoothly delivered to the negative pressure device. Attached Figure Description

[0017] To make the objectives, technical solutions, and advantages of the utility model embodiments clearer, the technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. The components of the utility model embodiments described and shown in the accompanying drawings can typically be arranged and designed in various different configurations.

[0018] In the description of the embodiments of the utility model, it should be noted that if terms such as "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," or "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the utility model product is in use, they are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the utility model. Furthermore, terms such as "first," "second," and "third" are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0019] Furthermore, the use of terms such as "horizontal," "vertical," and "sag" does not imply that the component must be absolutely horizontal or suspended, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0020] In the description of the utility model embodiments, "a plurality of" means at least two.

[0021] In the description of the embodiments of the utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the utility model according to the specific circumstances.

[0022] Combined with appendix Figure 1-2 As shown, a novel dual-channel puncture needle includes a puncture needle body 1, a negative pressure suction tube 2, a connector 3, and a flushing tube 4.

[0023] In practice, the materials of the negative pressure suction tube 2 and the flushing tube 4 can be set according to the actual situation. In this embodiment, both the negative pressure suction tube 2 and the flushing tube 4 are soft catheters, which can facilitate the operation of the puncture needle.

[0024] The puncture needle body 1 is a hollow cylindrical structure, and one end of the puncture needle body 1 is provided with a needle tip. In this embodiment, the diameter of the puncture needle body 1 is 2.9 mm and the length is 350 mm.

[0025] The puncture needle body 1 is provided with a needle core 5 along its axial direction to divide the puncture needle body 1 into two channels 6. The channels 6 extend along the axial direction of the puncture needle body 1. In practice, the needle core 5 divides the puncture needle body 1 into two flow channels, which can realize the negative pressure aspiration of cyst fluid in the cyst while injecting water into the cyst. It can facilitate the aspiration of cyst fluid by the negative pressure aspiration tube 2 and prevent blockage of the puncture needle body.

[0026] Both the negative pressure suction tube 2 and the flushing tube 4 are connected to the connector 3. The connector 3 is connected to the end of the puncture needle body 1 and connects the negative pressure suction tube 2 and the flushing tube 4 to the corresponding channel 6.

[0027] Specifically, the connector 3 is inserted into and fixedly connected to the puncture needle body 1 to form an integrated structure, ensuring the connection between the negative pressure suction tube 2, the flushing tube 4 and the puncture needle body 1. At the same time, the specifications of the negative pressure suction tube 2 and the flushing tube 4 can be selected according to the actual use. In this embodiment, the length of the negative pressure suction tube 2 is 950mm and the diameter is 2mm, and the length of the flushing tube 4 is 950mm and the diameter is 2mm.

[0028] In practical use, the puncture needle body 1 is inserted into the cyst. The cyst inside the cyst can be aspirated through the corresponding channel 6 in the puncture needle body 1 via the negative pressure suction tube 2. At the same time, water can be injected into the cyst through the corresponding channel 6 in the puncture needle body 1 via the flushing tube 4. This can dilute the viscous cyst fluid, making it easier for the negative pressure suction tube 2 to aspirate the cyst fluid. At the same time, it can prevent the cyst fluid from blocking the puncture needle body 1.

[0029] Furthermore, the cross-sectional area of ​​the channel 6 connected to the negative pressure suction tube 2 is larger than that of the channel 6 connected to the flushing tube 4. This ensures that water is injected through the channel 6 connected to the flushing tube 4, while also ensuring that the channel 6 connected to the negative pressure suction tube 2 can aspirate the cyst fluid and prevent the cyst fluid from blocking the puncture needle body 1 and the negative pressure suction tube 2 during the aspiration process.

[0030] The negative pressure suction tube 2 is connected to a plug 7 that is connected to a negative pressure aspirator. In use, the plug 7 is connected to the negative pressure aspirator. Through the operation of the negative pressure aspirator, negative pressure suction can be achieved on the negative pressure suction tube 2, thereby realizing negative pressure extraction of cyst fluid. The negative pressure extraction pressure can be adjusted according to the actual situation to meet the usage requirements under different circumstances.

[0031] It also includes a vacuum catheter 8, which is connected to a plug 7, and can realize the discharge of cyst fluid aspirated through the negative pressure suction tube 2.

[0032] In specific implementation of this invention, the puncture needle body 1 is inserted into the cyst through a laparoscopic puncture. Then, through the operation of the negative pressure suction device, negative pressure suction of the negative pressure suction tube 2 is achieved, thereby allowing negative pressure extraction of cyst fluid through the puncture needle body 1. Simultaneously, water is injected into the cyst through the flushing tube 4 to dilute the cyst fluid in the cyst, ensuring that the channel 6 connected to the negative pressure suction tube 2 can suction the cyst fluid and preventing the cyst fluid from blocking the puncture needle body 1 and the negative pressure suction tube 2 during the suction process. Finally, the cyst fluid suctioned through the negative pressure suction tube 2 is discharged through the vacuum catheter 8.

[0033] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
