The needle sleeve 2 is installed at the lower end of the structural sleeve 1, and the needle body 3 is inserted inside the needle sleeve 2. The upper end of the structural sleeve 1 is provided with a screw tube 4, and a screw rod 5 is installed inside the screw tube 4. The upper end of the interior of the structural sleeve 1 is provided with a telescopic cavity 6. The upper end of the needle body 3 extends into the interior of the telescopic cavity 6. The lower end of the screw rod 5 extends into the telescopic cavity 6 and is rotatably connected to the upper end of the needle body 3. Both sides of the interior of the telescopic cavity 6 are provided with sliding grooves 7. The upper end of the outer side of the needle body 3 is fitted with a sliding sleeve 8, and both sides of the sliding sleeve 8 are provided with protrusions 9. The protrusions 9 are movably adapted to the sliding grooves 7. The inner side of the sliding sleeve 8 is provided with an anti-rotation ring 10, and the inner side of the anti-rotation ring 10 is provided with an anti-rotation protrusion. The anti-rotation ring 10 is used to prevent the needle body 3 from rotating. In use, rotating the knob 13 drives the screw 5 to rotate. The screw 5 and the screw tube 4 are connected by a thread, which causes the screw 5 to rise and fall, thereby pushing the needle body 3 to extend and retract. This is used to adjust the length of the needle body 3. During the adjustment process, the anti-rotation ring 10 prevents the needle body 3 from rotating. With the movable connection of the bearing 11, the needle body 3 is prevented from rotating during the extension and retraction. The sliding sleeve 8 uses the protrusion 9 to limit the movement along the sliding groove 7, so that the needle body 3 is stable when it extends and retracts.

[0022] The lower end of the screw 5 is provided with a bearing 11, and the upper end of the needle body 3 extends to the inner side of the bearing 11. The screw 5 is rotatably mounted to the needle body 3 through the bearing 11.

[0023] The outer side of the screw pipe 4 is provided with handle rings 12, and the handle rings 12 are equidistantly provided with multiple groups, the outer side of the handle ring 12 is provided with anti-skid lines, the upper end of the screw rod 5 is provided with a knob 13, and the caliber of the knob 13 is larger than the caliber of the screw pipe 4. The setting of the structure sleeve 1 matches the handle ring 12 outside the screw pipe 4, which is convenient to hold and can assist in force application during use.

[0024] The lower end of the inner side of the structure sleeve 1 is provided with a fixed groove 14, the upper end of the needle sleeve 2 is inserted into the inside of the fixed groove 14 and is fixedly connected with the structure sleeve 1. It is convenient to install or dismount the needle sleeve 2.

[0025] The lower end of the needle body 3 is provided with a bending part 15, and the bending angle of the bending part 15 is 40°, and the thickness of the bending part 15 is 0.7 mm.

[0026] One end of the bending part 15 is a needle head, and the needle head is provided with a first cutting surface 16 and a second cutting surface 17, and the first cutting surface 16 and the second cutting surface 17 form a three-pronged sharp head. The resistance when passing through the skin tissue is reduced, and the pain of the patient is reduced.

[0027] One side of the needle sleeve 2 is provided with a connecting block 18, the lower side of one side of the structure sleeve 1 is provided with a sliding block 19, a flexible rod 20 is movably inserted into the sliding block 19, the lower end of the flexible rod 20 is provided with a hook 21, the hook 21 is connected with the connecting block 18, and the upper end of the flexible rod 20 is provided with a push button 22. When in use, the thumb presses and pushes the push button 22 upwards, pulls the flexible rod 20, and drives the connecting block 18 to displace, so as to pull the needle sleeve 2 and the needle body 3 to slightly bend, and the fine adjustment effect is achieved.

[0028] The skin surgery tissue stripping and perforating needle places the needle body 3 inside the needle sleeve 2 and the structure sleeve 1, rotates the knob 13, drives the screw rod 5 to rotate, utilizes the thread action of the screw rod 5 and the screw pipe 4, makes the screw rod 5 ascend and descend, and thus pushes the needle body 3 to stretch and retract, which is convenient to adjust the length of the needle body 3 to stretch out at any time, is convenient to use, and in the adjusting process, utilizes the action of the stop ring 10 to match the movable connection of the bearing 11, avoids the needle body 3 from rotating in the stretching and retracting process, utilizes the convex point 9 along the sliding groove 7 to limit the movable connection through the sliding sleeve 8, makes the needle body 3 more stable when stretching and retracting, and thus cannot shake or rotate, and reliability is guaranteed. Meanwhile, the setting of the structure sleeve 1 matches the handle ring 12 outside the screw pipe 4, which is convenient to hold, compared with directly holding the needle body 3, the perforating needle can assist in force application during use, and is convenient to apply force. In addition, the push button 22 can pull the flexible rod 20, so as to drive the connecting block 18 to displace, pull the needle sleeve 2 and the needle body 3 to slightly bend, and the fine adjustment effect is achieved. The function is diversified. Finally, the first cutting surface 16 and the second cutting surface 17 form a three-pronged sharp head, which reduces the resistance when passing through the skin tissue, and is beneficial to reduce the pain of the patient.
