Lung metal marker detection device and system

Abstract

The embodiment of the invention discloses a lung metal marker detection device and system. The detection device comprises a detection head, a connecting rod and a prompt unit, wherein the detection head comprises a supporting frame and a detection unit arranged on the supporting frame, and the supporting frame can drive the detection unit to be unfolded or folded; the connecting rod is connected with the supporting frame, a processing unit is arranged on the connecting rod, and is coupled with the detection unit; the prompting unit is coupled with the processing unit; the processing unit is used for driving the detection unit to generate a detection magnetic field, receiving detection magnetic field characteristic change caused by a metal marker, detected by the detection unit, convertingthe detection magnetic field characteristic change into a prompt electric signal and sending the prompt electric signal to the prompt unit; and the prompt unit converts the received prompting electricsignal into a prompting signal so as to prompt the position of the metal marker. According to the technical scheme provided by the embodiment of the invention, the detection head can extend into a human body for use, the metal marker placed in the lung and used for positioning a focus can be quickly positioned, and the operation time is shortened when wounds of a patient are reduced.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a detection device and system for a lung metal marker. Background technique [0002] With the development of imaging technology and the wide application of high-resolution CT in lung examination, more and more small pulmonary nodules have been detected. Since the nodules exist in the lung and are small in size and have tissue characteristics close to normal lung tissue, it is difficult to directly observe and identify them during surgery. Effective positioning of the nodules is required to ensure accurate nodule resection. [0003] The existing nodule marking methods all have certain defects, such as placing a hook line percutaneously for marking. When placing the hook line, it is necessary to adjust the puncture multiple times and perform CT scanning, which increases the trauma of the patient. Another example is to use a dye to stain the surrounding tissue. ...

AI Technical Summary

Problems solved by technology

Another example is to use a dye to stain the surrounding tissue. The dye is easy to diffuse and the labeling range is enlarged, and it is difficult to observe from the outside of the lung.

For another example, by placing metal markers, the metal markers are placed inside the lungs, and the position of the markers is not easy to find during the operation
