[0014] Beneficial effects:

[0015] 1. Install the fixing tube at the surgical hole, insert the fixing tube and silicone membrane, and after the insertion, evenly distribute the silicone membrane around the cyst. By pulling the vacuum tube, negative pressure is formed inside the vacuum groove, so that the edge of the vacuum groove can absorb the tissue around the cyst. A space connected to the outside world is formed by the fixing tube and the silicone membrane. The insertion depth of the silicone membrane is adjusted by the lifting tube to adapt to cysts in different positions. The bottom opening and closing of the silicone membrane is controlled by the opening and closing tube. The height position of the syringe is adjusted by the fine-tuning tube to facilitate accurate puncture.

[0016] 2. When fixing the fixing tube, disinfect the skin around the surgical hole. After disinfection, stick it around the surgical hole with an adhesive ring to isolate it from the outside environment. At this time, the only area in contact with the outside world is the cyst.

[0017] 3. When lifting, rotate the lifting cylinder so that the limiting cylinder drives the fitting cylinder to rotate through the limiting groove and the fitting block, so that the external thread on the outer wall of the fitting cylinder engages with the inner wall thread of the fixed cylinder, so that the fitting cylinder can be lifted and lowered to adapt to cysts in different positions.

[0018] 4. When opening and closing, the meshing tube rotates, so that the meshing external thread on the outer wall of the meshing tube meshes with a number of gears, and the gears rotate around their own rotation axis, so that the bottom end of the control rod can be opened and closed, thereby driving the bottom end of the silicone membrane to open or close through the control rod; when in use, the bottoms of a number of control rods are closed to form a conical structure, which makes the silicone membrane easier to insert; when sucking the tissue around the cyst, a number of control rods stretch the bottom of the bottom end of the silicone membrane, and at this time the bottom edge of the vacuum groove just contacts the tissue around the cyst, and by pulling the vacuum cylinder, the interior of the vacuum groove is evacuated into a negative pressure, so that the bottom of the silicone membrane is adsorbed on the tissue around the cyst through the vacuum groove.

[0019] 5. When adjusting the puncture height, first install the syringe into the inner tube, make the syringe block slide down from the top of the slide groove, and rotate the syringe to make the block enter the inner tube from the inside of the slide groove to complete the installation of the syringe. When fine-tuning the height, rotate the outer tube so that the thread engagement of the outer tube drives the inner tube to move up and down. The setting of the parallel block limits the rotation of the inner tube so that the inner tube can only move up and down in the vertical direction. At the same time, the setting of the parallel block and the cross bar can adaptively adjust the height of the fitting tube. The setting of the inner tube is provided through the internal thread connection of the outer tube, so that the syringe can perform precise puncture when performing puncture, so that the needle of the syringe can accurately puncture the outer wall of the cyst.

[0020] 6. By setting up a camera with light, medical personnel can illuminate the cyst by driving the camera and obtain the image of the cyst at the same time, making it easier for medical personnel to control the syringe for puncture.

[0021] 7. Compared with the prior art, the height position of the silicone membrane can be controlled by setting the fixed cylinder and the lifting cylinder of the present invention, so as to adapt to cysts in different positions. The silicone membrane can be adsorbed on the tissue outside the cyst through the vacuum groove by the setting of the silicone membrane. The silicone membrane forms an isolation protective layer so that only the cyst area is in contact with the outside world, reducing the contact area and reducing the risk of infection. The height position of the syringe can be fine-tuned by setting the adjustment cylinder and the fine-tuning cylinder. When puncturing, the puncture can be made more accurate by fine-tuning, avoiding excessive puncture. When puncturing, the camera with light can be illuminated and observed to facilitate puncture. The angle of the camera with light can be adjusted by adjusting the cylinder and the control rope. The outer wall of the meshing cylinder is provided with a meshing external thread, and the meshing external thread is meshed with a plurality of gears, so that the rotation of the meshing cylinder can drive the control rod to open and close. When the control rod is closed, the silicone membrane is easily inserted.
