[0002] A cyst is a benign disease that can grow on the surface of the human body or in the internal organs. A cyst is a benign cystic mass that grows on the surface of the body or in an internal organ. The contents are liquid. Generally speaking, common cysts include "kidney cysts", "liver cysts", "simple ovarian cysts" and "chocolate cysts". Kidney cysts are further divided into simple solitary renal cysts and polycystic kidney disease.

[0003] With the intervention and application of ultrasound-guided technology, cyst puncture is to first locate the cyst through ultrasound, then disinfect the skin at the puncture site, cover the area with a sterile towel, and after local anesthesia, make a small incision on the skin. The puncture needle is slowly inserted into the body through the skin incision, and then inserted into the cyst under ultrasound guidance. The cyst fluid is aspirated and a sclerosant is injected to perform cyst sclerotherapy. The advantages of cyst puncture and sclerotherapy are less traumatic and faster recovery.

[0004] Chinese Publication No. CN218960880U discloses a PTC puncture needle for cyst sclerosis, which uses an inner and outer tube combination and an expandable and contractible ball cage at the front end of the inner tube to reduce secondary damage that may occur during cyst puncture and treatment.

[0005] However, since the above-mentioned puncture needle is not provided with a side hole to enable the sclerosant to be fully sprayed on the cyst wall, there is a possibility that the cyst wall and tissue will block the tip of the tube, thereby affecting the treatment effect on the patient.

DETAILED DESCRIPTION

[0029] The following is a detailed description of the embodiments of the present invention with reference to the accompanying drawings.

[0030] like Figures 1-9 As shown, a cyst sclerosis drainage tube with a double-lumen pipeline includes a sclerosis main tube 1 and a sclerosis branch tube 2 formed on one side of the sclerosis main tube 1; the sclerosis branch tube 2 is arranged along the length direction of the sclerosis main tube 1, and a suction cavity 11 is formed in the sclerosis main tube 1, and a flushing cavity 21 separated from the suction cavity 11 is formed in the sclerosis branch tube 2; a flexible branch tube memory segment 22 is provided at the end of the sclerosis branch tube 2, and a main tube memory segment 12 that bends synchronously with the branch tube memory segment 22 is formed at the end of the sclerosis main tube 1, and the branch tube memory segment 22 and the main tube memory segment 12 are bent to form a pigtail-shaped structure 3; a plurality of extraction holes 4 for extracting cyst fluid are formed on the main tube memory segment 12, and a plurality of injection holes 5 for injecting sclerosant are formed on the branch tube memory segment 22.

[0031] The suction cavity 11 and the flushing cavity 21 are independently provided. The flushing cavity 21 is used for injecting the sclerosant, while the suction cavity 11 is used for aspirating the cyst fluid, thereby completing the sclerotherapy of the cyst by the effects of one injection and one extraction.

[0032] The branch memory segment 22 and the main memory segment 12 are made of memory material. When the branch memory segment 22 and the main memory segment 12 are not interfered with by external forces, the branch memory segment 22 and the main memory segment 12 bend to form a pig tail-shaped structure 3 under the action of their own memory. The pig tail-shaped structure 3 corresponds to the cyst setting, and the cyst is covered under the action of the pig tail-shaped structure 3, thereby increasing the area of the main memory segment 12 corresponding to the cyst, making it easier for the several extraction holes 4 on the main memory segment 12 to correspond to multiple angles of the cyst, thereby increasing the suction efficiency of the cyst fluid.

[0033] The main memory segment 12 is formed in the inner circle of the pigtail-shaped structure 3, and the corresponding extraction holes 4 are formed in the inner circle of the pigtail-shaped structure 3, and the extraction holes 4 are connected with the suction cavity 11. The main memory segment 12 formed in the inner circle of the pigtail-shaped structure 3 realizes moderate support for the outer wall of the cyst, prevents the cyst wall from collapsing and blocking the side holes, and is conducive to the suction of cyst fluid.

[0034] By synchronously controlling all the extraction holes 4 under the action of the suction chamber 11 , all the extraction holes 4 receive the suction force from the suction chamber 11 synchronously, thereby achieving the goal of extracting the cyst fluid into the suction chamber 11 through several extraction holes 4 until it is discharged from the opening of the suction chamber 11 .

[0035] The branch tube memory segment 22 is formed on the outer ring of the pigtail-shaped structure 3, and the corresponding several injection holes 5 are formed on the outer ring of the pigtail-shaped structure 3, and the several injection holes 5 are connected to the flushing cavity 21, and the branch tube memory segment 22 formed on the outer ring of the pigtail-shaped structure 3 is set back to the main tube memory segment 12.

[0036] By controlling all the injection holes 5 synchronously under the action of the flushing chamber 21 , the hardener is ejected synchronously from the plurality of injection holes 5 under the action of pressure.

[0037] A number of extraction holes 4 are arranged in sequence along the length direction of the branch pipe memory segment 22, and a number of injection holes 5 are arranged in sequence along the length direction of the main pipe memory segment 12, and the size of the injection holes 5 is smaller than the size of the extraction holes 4. The number of extraction holes 4 and injection holes 5 is set according to actual needs. Under the action of the small-sized injection holes 5, the hardener injected through the injection holes 5 has a greater injection speed. At the same time, the curved branch pipe memory segment 22 provides multiple injection angles for the injection holes 5, which is convenient for the hardener to fully flush the capsule wall.

[0038] The extraction hole 4 is connected to the injection hole 5 outside the hardening main pipe 1 and the hardening branch pipe 2. The extraction hole 4 can absorb the excess hardener or the hardener flowing to the extraction hole 4, thereby avoiding the residue of the hardener.

[0039] A pointed needle 6 or a blunt needle 7 is inserted into the hardened main pipe 1 to straighten the pigtail-shaped structure 3. The pointed needle 6 and the blunt needle 7 are both straight structures and are made of hard material.

[0040] Both the pointed needle 6 and the blunt needle 7 can achieve the deformation of the pigtail-shaped structure 3. When the pointed needle 6 or the blunt needle 7 is connected to the hardened main pipe 1 and the main pipe memory segment 12, the main pipe memory segment 12 is straightened under the action of the pointed needle 6 or the blunt needle 7 made of hard material, thereby synchronously straightening the branch pipe memory segment 22 under the straightening action of the main pipe memory segment 12, realizing the overall straightening of the pigtail-shaped structure 3, and meeting the need to puncture the cyst by the pointed needle 6.

[0041] The pointed needle 6 is set through the hardened main tube 1, and the length of the pointed needle 6 is not less than the length of the hardened main tube 1. The two ends of the pointed needle 6 are respectively formed with a pointed structure 62 for puncturing the cyst and a pointed needle end 61 for inserting and removing the pointed needle 6.

[0042] The pointed needle 6 is used in the initial stage of puncturing the cyst. When the length of the pointed needle 6 is not less than the length of the hardened main tube 1, the pointed needle end 61 can be ensured to pass through the hardened main tube 1 and the cyst can be punctured under the action of the pointed needle end 61.

[0043] The length of the blunt needle 7 is not greater than that of the hardened main tube 1 , and the cross-sectional dimensions of the blunt needle 7 correspond to those of the hardened main tube 1 . A blunt needle tip 71 for inserting and removing the blunt needle 7 is formed at the end of the blunt needle 7 .

[0044] The blunt needle 7 is used after the cyst sclerotherapy is completed. The blunt needle 7 is inserted into the sclerotherapy main tube 1 to straighten the pigtail-shaped structure 3. At this time, the outer wall of the blunt needle 7 is tightly fitted with the inner wall of the sclerotherapy main tube 1, so that the residual liquid in the sclerotherapy main tube 1 is completely discharged under the action of the blunt needle 7, thereby reducing the residual hardener in the sclerotherapy main tube 1.

[0045] Under the action of the blunt needle 7, the blunt needle 7 is moved along the length direction of the hardened main tube 1 to squeeze the residual liquid in the hardened main tube 1 and the hardened branch tube 2. Therefore, under the squeezing action of the blunt needle 7, the residual liquid in the hardened main tube 1 and the hardened branch tube 2 is discharged under the action of pressure, thereby reducing the residual hardener in the hardened main tube 1 and the hardened branch tube 2.

[0046] The hardened branch pipe 2 is arranged in a covering manner on a portion of the hardened main pipe 1. A flushing connector 23 for injecting liquid into the flushing cavity 21 is formed at the end of the hardened branch pipe 2. The flushing connector 23 is used to be connected to the hardening agent syringe to inject the hardener into the hardened branch pipe 2 through the flushing connector 23.

[0047] A suction connector 13 for suctioning the suction chamber 11 is formed at the end of the hardened main tube 1. The suction connector 13 is used to be connected to a syringe. Under the action of the syringe, a negative pressure effect is achieved in the suction chamber 11, thereby adding a suction effect to the plurality of extraction holes 4.

[0048] The hardened main tube 1 and the hardened branch tube 2 are an integrated double-lumen structure. A scale 24 is formed on the hardened branch tube 2 along the length direction of the hardened branch tube 2. The scale 24 can display the insertion depth of the hardened main tube 1 and the hardened branch tube 2 to ensure that the insertion position of the hardened main tube 1 and the hardened branch tube 2 corresponds to the cyst position.

[0049] A pipeline clamp 8 for sealing the connection state of the hardened branch pipe 2 is installed on the hardened branch pipe 2. The pipeline clamp 8 is sleeved on the hardened branch pipe 2, and a closing port and a connection port for controlling the connection state of the hardened branch pipe 2 are formed on the pipeline clamp 8. By adjusting the position of the pipeline clamp 8 on the hardened branch pipe 2, the connection state of the hardened branch pipe 2 can be controlled. When the hardened main pipe 1 is in the suction state, the connection state of the hardened branch pipe 2 can be sealed by the pipeline clamp 8, thereby ensuring stable extraction of cystic fluid by the hardened main pipe 1.

[0050] A hardened main tube 1 and a hardened branch tube 2 with different diameters can be provided, which is suitable for puncture and hardening treatment of cysts of the liver, kidney, thyroid, etc., as well as irrigation and drainage of peritoneal effusion and necrotic tissue. It can be used for one-time treatment and long-term retention. The extraction hole 4 at the pigtail-shaped structure 3 is used for cyst fluid aspiration; the peripheral injection hole 5 is used for irrigation, which can provide a higher flow rate.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
