BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Figure 1 It is a structural schematic diagram of the present invention. DETAILED DESCRIPTION

[0015] The following combination Figure 1 The present invention is described in detail. The exemplary embodiments and descriptions of the present invention are used to explain the present invention but are not intended to limit the present invention.

[0016] like Figure 1 The present invention provides an ovarian cyst removal and leakage prevention device, which includes a hollow puncture needle 1, the end of the needle tube of the puncture needle is connected to a laparoscopic suction connector (not shown in the figure). After the needle tip of the puncture needle punctures the ovarian cyst wall, the laparoscope sucks out the cystic fluid in the cyst from the puncture needle cavity 11 through the laparoscopic suction connector; thus, the present invention uses the laparoscope and the hollow puncture needle to achieve the purpose of external suction of cystic fluid and achieves the purpose of treating ovarian cysts; at the same time, the puncture needle of the present invention is provided with an adhesion device 2. When the cystic fluid is sucked out, the adhesion device covers the puncture hole formed in the cyst wall by the needle tip puncture, thereby blocking the puncture hole and preventing the cystic fluid from leaking out.

[0017] The puncture needle of the present invention is 30-40 cm long and 0.3-0.5 cm in diameter, with a preferred length of approximately 35 cm and a diameter of approximately 0.3 cm to meet the needs of clinical surgery. The adhesive device is positioned 1-2 cm from the needle tip, where the puncture hole is located, to ensure that the adhesive device covers the puncture hole. Because the adhesive device strongly adheres to the cyst wall, preventing cystic fluid from leaking out of the puncture hole, after the needle tip punctures the cyst wall and draws out the cystic fluid, the puncture hole is sealed and covered by the adhesive film, thereby preventing cystic fluid from leaking out.

[0018] The adhesive device of the present invention is a retractable or expandable detachable umbrella-shaped adhesive device. When expanded, the device takes on an umbrella shape, and the puncture needle is located in the center of the umbrella shape, thereby covering the puncture hole. Preferably, the detachable umbrella-shaped adhesive device includes a retractable or expandable balloon 21, which takes on an umbrella shape when expanded. During surgery, the opening of the umbrella-shaped balloon rests against the balloon wall, while the area below the balloon opening is sealed and covers the puncture hole, thereby preventing leakage of cystic fluid. Generally, the diameter of the balloon opening is 1-1.5 cm, preferably about 1 cm, to meet the needs of clinical surgery. Before surgery, the balloon shrinks to a membrane-like shape and adheres to the puncture needle, which does not interfere with surgical puncture. Thus, the present invention achieves the purpose of detachable umbrella-shaped adhesion through a retractable or expandable balloon.

[0019] During implementation, the puncture needle is covered with a flexible sleeve 22, onto which the balloon is mounted. The sleeve and balloon are integrally formed, making them not only convenient for processing and assembly but also providing a tight connection, eliminating gaps and preventing leakage of cystic fluid. The sleeve of the present invention is sealed to the puncture needle, preventing cystic fluid from escaping through the gap between them during puncture. The flexible material of the sleeve is typically medical silicone. Due to its inherent elasticity, the sleeve's diameter is set smaller than that of the puncture needle during processing. This creates an interference fit when placed on the puncture needle, eliminating any gaps and preventing cystic fluid from leaking. The sleeve also facilitates the positioning of the adhesive device, which must be positioned 1-2 cm from the needle tip. Its flexibility and elasticity allow for easy movement over the puncture needle, ensuring a sealed connection and maintaining the sleeve's position within the desired 1-2 cm distance.

[0020] The detachable umbrella-shaped adhesive device of the present invention also includes a channel 23 passing through the puncture needle and the sheath. Gas or liquid can be introduced into the balloon through this channel, thereby controlling the pressure within the balloon, ensuring an appropriate fit between the balloon and the balloon wall, and preventing leakage of balloon fluid. Furthermore, the channel is disposed within the puncture needle so as not to interfere with surgical procedures. Preferably, the detachable umbrella-shaped adhesive device also includes an adhesive film 24 fixedly disposed on the plane of the balloon near the needle tip. The adhesive film can be formed from silicone clay, for example. Since silicone clay is inherently sticky, the film has an adhesive effect. When the balloon is inflated, the adhesive film adheres to the balloon wall, further improving the seal between the balloon and the balloon wall.

[0021] During the procedure, the umbrella-shaped balloon and attached film can also collect any cystic fluid remaining on the puncture needle after they shrink, preventing it from leaking out. Because of the use of the umbrella-shaped balloon and attached film, even if a small amount of cystic fluid flows out of the puncture hole during puncture, it will only flow into the groove of the umbrella-shaped balloon. Therefore, when the puncture needle is withdrawn after the procedure is completed, any cystic fluid that may remain on the puncture needle enters the groove of the balloon. Then, the gas or liquid within the balloon is extracted. At this time, the balloon shrinks, and it and the attached film cover the cystic fluid in the groove. The attached film can adhere to the puncture needle, and then the puncture needle is completely withdrawn. This not only collects any cystic fluid that may remain on the puncture needle, but also any cystic fluid that may leak out of the puncture hole, thus completely preventing the leakage of cystic fluid.
