[0030] The punching device is used to form fixing holes on the positioning mechanism 101 so as to fix the bipolar electrocoagulation device 201 at different positions.

[0031] Among them, the positioning mechanism 101 is a flexible positioning strip marked with scales 102, whose cross-section is semicircular and hollow inside, and is made of elastic and plastic materials such as silicone rubber, has curvature, can adjust the length, and can fit tightly against the chest wall 4-3; the plane of the positioning mechanism 101 is the contact surface with the chest wall 4-3, and the contact surface of the positioning mechanism 101 has a plurality of self-priming suction cups 103, and the plurality of self-priming suction cups 103 are used to fix the positioning mechanism 101 on the chest wall 4-3, and the position of the positioning mechanism 101 on the chest wall is adjusted by the doctor according to the patient's specific conditions and surgical needs; the positioning mechanism 101 and the bipolar electrocoagulation device 201 are used in combination to assist in the precise positioning of lung nodules in laparoscopic surgery.

[0032] The self-priming suction cup 103 has sufficient suction force and can be firmly fixed on the chest wall 4-3 during surgery to maintain the stability of the device. The design of the self-priming suction cup 103 makes it suitable for various chest wall surfaces and has good adaptability and durability. The positioning mechanism 101 can measure the positioning distance according to the chest CT examination and is used to determine the location of the lung nodules during surgery.

[0033] In this embodiment, in order to ensure the electrocoagulation marking effect, the bipolar electrocoagulation device 201 is a bipolar electrocoagulation hook.

[0034] In order to facilitate the connection of the power supply, the high-frequency generator 203 is connected to the power plug 206 via the power cord 205; in order to facilitate the assembly of the bipolar electrocoagulation device 201 and the connecting line 202, a socket 207 is fixedly installed at the end of the connecting line 202 away from the high-frequency generator 203, and the connection terminal of the bipolar electrocoagulation device 201 is inserted into the socket 207 through the fixing hole on the positioning mechanism 101.

[0040] Step 2: Measure the positioning distance L through the chest CT cross-sectional image. First, mark the point B where the lung nodule is closest to the lung surface on the chest CT cross-sectional image. Mark the point beside the spine in the same cross-sectional image as B. Record the specific number of ribs. The positioning distance L is the distance from point A along the lung surface to point B.

[0041] Step 3: After the patient is anesthetized, disinfected, and draped, and after tracheal intubation, an appropriate intercostal incision is made, and a thoracoscope is inserted for exploration to preliminarily determine the location of the lung nodule.

[0042] Step 4: Take the positioning distance L as the electrocoagulation position in the positioning device, use the puncher 31 to punch a hole, and then insert the bipolar electrocoagulation device 201. The bipolar electrocoagulation device 201 is connected to the high-frequency generator 203, and the control button 204 is used to control whether to perform electrocoagulation.

[0043] Step 5: Place one end of the positioning mechanism 101 beside the aforementioned specific rib spine, in a direction parallel to the cross-section of the human body, with the bipolar electrocoagulation device 201 facing the visceral pleura and the contact surface of the positioning mechanism 101 facing the parietal pleura, and fix it on the chest wall 4-3 by pressing the self-priming suction cup 103 to generate negative pressure.

[0044] Step 6: At this time, ask the anesthesiologist to inflate the lung until the operated lung is fully expanded, turn on the bipolar electrocoagulation device 201 to mark the location of the lung nodule, perform single-lung ventilation until the operated lung is completely collapsed, confirm the location of the lung nodule again, and perform wedge-shaped resection of the lung nodule 4-1.
