Abstract
The invention discloses a cruising locator for pulmonary minimal focuses under a thoracoscope. A navigation probe is arranged at the tip of a pair of lung grasping forceps, and a micro-electromagnetic sensor is arranged inside the navigation probe. The cruising locator is matched with an in-vitro electromagnetic locating panel, an electromagnetic patch and an electromagnetic navigation host, and is used for performing chest CT scanning and three-dimensional reconstruction on the scanned image to obtain a chest three-dimensional analog image, a doctor marks location and size of a doubtable focus position in the analog image and inputs the marked image to the electromagnetic navigation host, and the system is used for automatically simulating an optimized location navigation path, so that a pulmonary minimal focus can be easily located by utilizing the navigation probe under guidance of a real-time navigation system in the thoracoscopy. The cruising locator is simple in structure, can be used for accurately and quickly reaching a target focus and avoiding the operation risk generated when location is carried out in other operations, has relatively low requirement for doctors and patients, is safe and reliable to operate, and has a good practical value.
Description
Technical field
The present invention relates to thoracoscopic operation technique with the apparatus field, under a kind of thoracoscope, lung minimal disease cruises localizer specifically.
Background technology
Along with the development of iconography and the enhancing of Results of Mass Screening for Lung Cancer dynamics, the quantity of Small pulmonary nodule increases year by year, video-assistant thorascope technology has been widely used in the nodular diagnosis and treatment of solitary Lung, and can the key factor limiting success rate of operation locate focus quickly and accurately, when lack safety, effectively, accurately location measure, have some cases in being forced to, to turn on the situation of breast because cannot focus be found.
Current small pulmonary artery location technology mainly comprises following four kinds: 1. injecting fluid location: institute's injecting fluid comprises the dyestuffs such as methylene blue, contrast medium, radionuclide and sclerosing agent, the method defect is liquid oriented tissue diffusion tendency, still likely cannot accurately locate in art, if and non-water-soluble liquid is not intended to inject in Pulmonary Vascular, the danger of system thromboembolism can be increased; 2.CT Guided Percutaneous places seal wire or microcoils: though the method can accurately be located in the preoperative, movable before needing strict restriction operation in patients, and has the probability that seal wire or turn come off, and also has and the pneumothorax even danger of hemopneumothorax occur; 3. intraoperative ultrasound location: the method is higher to doctor's technical requirement, and need the complete atrophy of Ipsilateral lung in art, for unworkable emphysema patient, and there is pulmonary fibrosis patient that is serious or adverse cardiac to be also difficult to utilize unilateral lung to maintain ventilation, add at operation risk; 4. Intraoperative position method: in conjunction with swollen lung method in art, according to relatively-stationary anatomical landmarks, surperficial using electric knife calcination as labelling at lung after swollen lung, the clinical diagosis experience that the method needs doctor to enrich, the thorough understanding of dissecting lung section, need constantly take exercise.
Therefore, for overcome above-mentioned technology deficiency and design a operation risk little, can accurately locate, simple and convenient, safe and reliable, patient and doctor to be required under low a kind of thoracoscope to lung minimal disease cruises localizer, just inventor's problem to be solved.
Summary of the invention
For the deficiencies in the prior art, the object of this invention is to provide lung minimal disease under a kind of thoracoscope to cruise localizer, its structure is simple, easy to operate, safe and reliable, small pulmonary artery location difficulty problem in video assisted thoracic operation can be solved, operation risk is little, can accurately locate required operative site, low to the requirement of patient and doctor.
The technical solution adopted for the present invention to solve the technical problems is: under a kind of thoracoscope, lung minimal disease cruises localizer, it comprises lung grasping forceps, navigation probe, described lung grasping forceps tip is provided with navigation probe, and described navigation probe inside is provided with micro-electromagnetic inductor.
Further, under described thoracoscope, the lung minimal disease localizer auxiliary facility that cruises comprises external electromagnetic location plate, electromagnetism paster, electromagnetic navigation main frame.
The invention has the beneficial effects as follows:
1, the present invention arranges micro-electromagnetic inductor by the navigation probe that has in thoracoscope lung grasping forceps tip sleeve, labelling can be carried out to the position at suspicious tuberosity position and size in analog image, system automatic mold draws up best located guidance path, guide convenient and swift, targeted site can be arrived rapidly and accurately, the operation risk produced when simultaneously avoiding other location of operation, also lower to the requirement of doctor and patient, handling safety is reliable.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is using state structural representation of the present invention.
Description of reference numerals: 1-navigation probe; 2-lung grasping forceps; The 3-lobe of the lung.
Detailed description of the invention
Below in conjunction with specific embodiment, set forth the present invention further, should be understood that these embodiments are only not used in for illustration of the present invention and limit the scope of the invention.In addition should be understood that those skilled in the art can make various changes or modifications the present invention after the content of having read the present invention's instruction, these equivalent form of values drop on application appended claims limited range equally.
Structural representation of the present invention see Fig. 1, under a kind of thoracoscope of this structure, lung minimal disease cruises localizer, it comprises navigation probe 1, lung grasping forceps 2, described lung grasping forceps 2 tip is provided with navigation probe 1, described navigation probe 1 inside is provided with micro-electromagnetic inductor, and under thoracoscope, the lung minimal disease localizer auxiliary facility that cruises comprises external electromagnetic location plate, electromagnetism paster and electromagnetic navigation main frame.
Using state structural representation of the present invention see Fig. 2, the present invention when in use, operation consent carries out Thoracic CT scan to patient, and the scanning gained lobe of the lung 3 image is carried out three-dimensional reconstruction, obtain chest three-dimensional simulation image, in analog image, labelling is carried out to the position at suspicious tuberosity position and size by doctor, then by image good for labelling input electromagnetic navigation main frame, draw up best located guidance path by system automatic mold.
In art, its auxiliary facility electromagnetic location plate is placed in patient's dorsal part, uniform electromagnetic field is produced in patient chest scope, before electromagnetism paster is affixed on patient chest, the three-dimensional position of induction navigation probe 1, then video assisted thoracic operation is carried out, now, the present invention is inserted by operation technique hole, navigation probe 1 is placed in lung surface, navigation probe 1 internal electrical magnetic inductor passes through transmission of electromagnetic signals, mark position in analogue navigation figure shows, and by signal correction course, finally localizing objects lung minimal disease under real-time navigation system guides, improve lung minimal disease locating accuracy in video assisted thoracic operation.
Structure of the present invention is simple, can arrive targeted site rapidly and accurately, avoids the operation risk that other operations produce when locating simultaneously, and also lower to the requirement of doctor and patient, handling safety is reliable, has extraordinary practical value.
