The present disclosure provides a tissue imaging method, including: inserting an electronic probe into a lesion area of a patient and ablating tissue of the lesion area; capturing a first image including the lesion area by using an imaging apparatus; vibrating the electronic probe to generate displacement of at least a portion of the tissue of the lesion area, and capturing a second image including the lesion area by using the imaging apparatus; generating a correlation image according to a correlation between the first image and the second image; and computing an ablation boundary according to the correlation image.

Tissue imaging method

An ablation device including a first electrode, at least one second electrode and a guiding sleeve is provided. The guiding sleeve is sleeved outside the first electrode and the second electrode, so as to fold the second electrode. The guiding sleeve is adapted to move along an axial direction of the first electrode, so as to adjust a length of the first electrode exposed by the guiding sleeve and enable the second electrode to be released and expand in a radial direction of the first electrode.

Ablation device

Provided is a bipolar electrode probe, which includes a conductive needle, an insulation layer, a conductive sleeve, and an insulation sleeve. The conductive needle has a longitudinal direction and a transverse direction perpendicular to the longitudinal direction. The insulation layer covers the conductive needle and has a first opening. The conductive sleeve covers the insulation layer and has a second opening. The insulation sleeve covers the conductive sleeve. When the bipolar electrode probe is turned on, a longitudinal electric field is formed from a front end of the conductive needle to the conductive sleeve along the longitudinal direction. A transverse electric field is formed from the conductive needle to the conductive sleeve via the first opening and the second opening along the transverse direction.

Bipolar electrode probe

A radiofrequency ablation electrode needle includes at least one first segment and at least two second segments. The at least one first segment and the at least two second segments are exposed on a surface of the needle body. An impedance of the at least one first segment is smaller than an impedance of the at least two second segments and at least one of the at least one first segment is disposed between two immediately adjacent ones of the at least two second segments. Besides, the radiofrequency ablation electrode needle is a monopolar electrode needle.

A needle guide system is provided. The needle guide system includes a puncture device, an ultrasound transducer, a first orientation detector, a second orientation detector, a proximity detector and a processor. The ultrasound transducer is configured to obtain an ultrasound image. The first orientation detector is disposed on the puncture device, and the second orientation detector is disposed on the ultrasound transducer. The proximity detector is disposed on at least one of the puncture device and the ultrasound transducer, configured to obtain a relative distance between the puncture device and the ultrasound transducer. The processor is configured to obtain a spatial relationship between the puncture device and the ultrasound transducer by using the first orientation detector, the second orientation detector, and the proximity detector, and predict a trajectory of the puncture device in the ultrasound image according to the spatial relationship.
