Description

Technical Field

[0001] This invention belongs to the field of lung nodule localization, specifically a magnetic collar and electrode needle combination localization system used in lung nodule resection surgery. Background Technology

[0002] Pulmonary nodules refer to focal, round, dense shadows of various sizes, with clear or blurred borders, and a diameter of 3 cm or less on lung imaging. Pulmonary nodules do not grow on the lung surface but inside the lung. Some are near the hilum, and some are near the chest wall. Pulmonary nodules can also be of three types: First, inflammatory nodules, which can be located anywhere in the lung, as the location is not precise due to inflammation, and are not necessarily near the hilum or chest wall. Second, tuberculous nodules, which may be disseminated tuberculosis; sometimes both lungs are covered with tuberculous nodules. Third, tumor nodules in the lung; if it is central lung cancer, it is near the hilum; if it is peripheral lung cancer, it is far from the hilum.

[0003] Precise localization remains a challenge in current lung nodule surgery. Accurate intraoperative localization of lung nodules is crucial for successful resection. However, lung nodules are located inside the lung and are difficult to identify from the lung surface, increasing the difficulty of the surgery and the risk of potential complications. Therefore, thoracic surgeons urgently need a more precise and safer technique for lung nodule resection and localization. Summary of the Invention

[0004] To address the aforementioned problems, the present invention aims to provide a magnetic collar and electrode needle combination positioning system for lung nodule resection surgery, which can leave a mark on the lung surface through the electrode needle, facilitating the determination of the location of lung nodules during surgery.

[0005] To achieve the above objectives, the technical solution of the present invention is as follows: a magnetic collar and electrode needle combination positioning system for lung nodule resection surgery, comprising:

[0006] Medical Imaging Module: Used to obtain perspective views of the lungs;

[0007] Real-time imaging module: used to acquire images of the patient's body in real time for positioning guidance;

[0008] Positioning module: includes several pairs of magnetic collars and electrode needles;

[0009] The magnetic collar has holes for the electrode needles to pass through. The magnetic collar is used to be placed on both sides of the chest cavity and fixed in position by magnetic attraction.

[0010] The electrode needle is electrically connected to a current generator, which generates a current that causes minimal damage to the lungs and leaves a visible mark.

[0011] The above solution has achieved the following beneficial effects: the medical imaging module is used to obtain lung perspective images, which allow users to observe the condition of the patient's lungs and determine the location of lung nodules.

[0012] Magnetic rings are used to mark the location of lung nodules on the patient's body surface. After thoracotomy, the approximate location of the lung nodules can be determined with the help of a medical imaging module. Utilizing the magnetic attraction of the magnetic rings, a pair of magnetic rings are placed on the inside and outside of the patient's chest cavity, respectively. The holes of the magnetic rings are aligned with the lung nodules, and the magnetic rings will clamp and fix them to the patient's chest cavity under the magnetic attraction.

[0013] The electrode needle is inserted into the patient's chest cavity through the hole in the magnetic collar. The location of the lung nodule is obtained using a real-time imaging module. The insertion of the electrode needle is controlled, and the real-time imaging module ensures that the electrode needle is inserted into the lung nodule. The current generator is activated, and the electrode needle conducts current to generate an electric shock mark on the surface of the patient's lung.

[0014] During surgery, users can easily locate the electrical stimulation marks on the surface of the patient's lungs. Cutting open the electrical stimulation marks exposes the lung nodules to the operating field, thereby improving the accuracy of the surgery and reducing the difficulty of the surgery. This facilitates the precise removal of lung nodules and reduces the possibility of surgical errors.

[0015] Furthermore, the magnetic collar is equipped with a magnetic suction element, and the magnetic suction element is covered with a biocompatible elastic material layer.

[0016] Beneficial effects: The attraction between the magnetic collars can clamp into the patient's chest tissue, easily causing tissue damage. A biocompatible elastic material layer provides a cushioning layer, reducing the surface rigidity of the magnetic collars and improving the patient's experience.

[0017] Furthermore, the magnetic collar located on the outside of the chest cavity is equipped with adhesive tape.

[0018] Beneficial effects: The adhesive tape can stick the magnetic ring to the skin surface, reducing the probability of the magnetic ring slipping or falling off.

[0019] Furthermore, a connecting rod is fixedly connected to the end of the electrode needle away from the needle tip, and the connecting rod is made of insulating material.

[0020] Beneficial effect: After the electrode needle is inserted into the pleural cavity, the current flowing through it can also affect the thoracentesis site. By using a connecting rod, the current transmission can be interrupted, reducing the impact on the thoracentesis site.

[0021] Furthermore, the medical imaging module is either CT or MRI.

[0022] Beneficial effects: The medical imaging module provides a fluoroscopic view of the patient's lungs, making it convenient for users to observe lung nodules.

[0023] Furthermore, the length of the electrode needle is 10 to 15 cm.

[0024] Beneficial effects: By setting an appropriate electrode needle length, it is easier for users to operate. Attached Figure Description

[0031] Example 1

[0032] The basic implementation examples are as follows: Figure 1 To be continued Figure 4 As shown:

[0033] A magnetic collar 1 and electrode needle 2 combined positioning system for use in pulmonary nodule resection, comprising:

[0034] Medical Imaging Module: The medical imaging module is a CT scanner used to acquire transillumination views of the lungs;

[0035] Real-time imaging module: used to acquire images of the patient's body in real time for guidance in locating lung nodules;

[0036] Positioning module: includes a pair of magnetic collars and electrode needles;

[0037] The magnetic collar 1 includes a magnetic suction element 3, the magnetic suction element 3 is wrapped with a biocompatible elastic material layer 4, the magnetic collar 1 has a hole 5 for the electrode needle 2 to pass through, the magnetic collar 1 is used to be set on the inside and outside of the thoracic cavity and magnetically fixed; the magnetic collar 1 located on the outside of the thoracic cavity is glued and fixed with adhesive tape 6.

[0038] The electrode needle 2 is electrically connected to a current generator, which is used to generate a current that causes low damage to the lungs and leaves a visible mark. The end of the electrode needle 2 away from the needle tip is fixedly connected to a connecting rod 7, which is made of insulating material. The end of the connecting rod 7 away from the electrode needle 2 is glued and fixed to a handle 8. The length of the electrode needle 2 is 10 to 15 cm.

[0039] The specific implementation process is as follows: The medical imaging module is used to obtain a lung perspective view, which allows users to observe the condition of the patient's lungs and determine the location of lung nodules.

[0040] Magnetic rings 1 are used to mark the location of lung nodules on the patient's body surface. After thoracotomy, with the help of a medical imaging module, the location of the lung nodules is determined. Utilizing the magnetic attraction of the magnetic rings 1, a pair of magnetic rings 1 are placed on both the inner and outer sides of the patient's chest cavity. The holes 5 of the magnetic rings 1 are aligned with the lung nodules, and the magnetic rings 1 are clamped and fixed to the patient's chest cavity under magnetic attraction. During use, adhesive tape 6 can be used to adhere the magnetic rings 1 to the skin surface, reducing the probability of the magnetic rings 1 slipping or falling off.

[0041] Electrode needle 2 is inserted into the patient's chest cavity through the hole 5 of the magnetic collar 1. After the lungs are inflated, guided by the location of the lung nodules in the real-time imaging module, electrode needle 2 is ensured to be inserted into the lung nodules. The current generator is then activated, and electrode needle 2 conducts current to create an electrical shock mark on the surface of the patient's lungs. By setting an appropriate current value, a visible electrical shock mark is created. Subsequent surgery will make an incision at the electrical shock mark, and the surgical incision will cover the damage caused by the mark. Therefore, the impact of lung damage caused by the electrical shock mark is negligible.

[0042] Preoperative localization of lung nodules is achieved using a medical imaging module, followed by insertion and marking of electrode needles guided by a real-time imaging module. This allows for precise localization of lung nodules with minimal invasiveness, preventing further damage to the patient due to incorrect surgical incisions.

[0043] After the electrode needle 2 is inserted into the pleural cavity, the current flowing through it will also affect the thoracentesis site. By using the connecting rod 7, the current transmission is interrupted, reducing the impact on the thoracentesis site.

[0044] When users view the lungs through the real-time imaging module, they can easily find the location of the electrical shock markers on the surface of the patient's lungs. Cutting open the electrical shock markers exposes the lung nodules to the operating field, thereby improving the accuracy of the operation and reducing the difficulty of the operation.
