Description

Pulmonary nodule puncture positioning system

Technical Field

The utility model relates to the technical field of operation positioning, in particular to a pulmonary nodule puncture positioning system.

Background

The pulmonary nodule puncture requires a puncture needle to penetrate the lung of a patient and then obtain pulmonary tissue or treat, which has the advantages of low invasiveness and low trauma. At present, the commonly used lung puncture is preceded by chest CT scanning, the nature of the tumor is determined, and then the operation is performed after puncture marks are made on the skin. Because the focus position can not be fixed all the time under the influence of respiration, a doctor must estimate the needle penetration depth and the needle penetration direction after determining the needle penetration point, and the needle penetration depth and the needle penetration direction are required to be adjusted repeatedly according to the CT scanning result each time, so that repeated needle penetration is caused, and pain and complications are brought to a patient.

Detailed Description

For a further understanding of the present utility model, the following examples are set forth.

Referring to fig. 1, a lung nodule puncture positioning system comprises a positioning needle 1, a puncture needle 2, a CT scanner 3 and an imaging system 4; the positioning needle 1 is provided with a first position sensor 11 for providing coordinate information of the positioning needle 1; the puncture needle 2 is provided with a second position sensor 21 for providing coordinate information of the puncture needle 2; the imaging system 4 is communicatively connected to the first position sensor 11, the second position sensor 21 and the CT scanner 3, respectively.

In a preferred embodiment, the imaging system comprises a processing unit and a display unit, the processing unit acquiring data of the CT scanner and data of the first and second position sensors and displaying in the display unit. The imaging system is a three-dimensional imaging system.

The first and second position sensors are located at the needle tip and communicate coordinate information data to the imaging system in real time.

The imaging system is characterized by further comprising a sliding table, the sliding table is used for bearing and fixing a patient, the imaging range of the imaging system is associated with the table top of the sliding table, the coordinate positions of the first position sensor and the second position sensor are also associated with the sliding table, the position of the sliding table is used as a coordinate zero point, and the positions of the lung nodule, the first position sensor and the second position sensor are conveniently located.

Working principle:

the patient is fixed on a sliding table, then pushed into a CT scanner 3 to scan the lung 5 and withdraw from the scanner 3, a positioning needle 1 is penetrated around a focus of the patient according to CT image guidance, the patient is simultaneously sent into the CT scanning again, the coordinate position of the nodule 6 of the lung 5 and the coordinate position image information of a first position sensor 11 are transmitted into an imaging system 4 and displayed by a display unit, after the scanning is finished, the patient is withdrawn from the CT scanner 3, the imaging system 4 calculates the azimuth relation between the nodule 6 and the first position sensor 11 through a processing unit, and when the lung 5 expands and contracts along with breathing, the position of the first position sensor 11 changes along with the nodule 6, so the position of the nodule 6 can be calibrated through the position of the first position sensor 11. The first position sensor 11 is in communication connection with the imaging system 4, so that the real-time coordinate position of the first position sensor 11 is transmitted to the imaging system 4, the imaging system 4 can display the position change condition of the first position sensor 11 in real time, and because the nodule 6 and the first position sensor 11 are follow-up, the position of the nodule 6 of the lung 5 scanned by the CT scanner 3 can take the image information of the coordinate position of the first position sensor 11 as a reference, thereby obtaining an accurate position and image of the nodule 6 which changes in real time, further using the accurate position of the puncture needle 2 for entering the nodule 6, and the second position sensor 21 transmits the coordinate position of the puncture needle 2 in real time, so that the puncture biopsy condition can be observed in real time through the display unit of the imaging system 4, and the method is simple, convenient and accurate.
