The conventional ablations at present comprise cryoablation, radiofrequency ablation, irreversible electroporation ablation, microwave ablation and the like, and the range of the ablations is required to be enlarged by combining multiple needles.
Before treatment, an ablation plan is firstly required to be made, specifically, tumor positioning is firstly carried out through CT or MRI, the size of a target tumor is calculated, the tumor ablation range is calculated according to the size of the tumor, then the required number of probes is evaluated, and finally the placement position of each probe is determined. Tumor ablation is realized by selecting the number of ablation needles and a certain needle distribution method. For either thermal or cold ablation, the probe configuration determines the ablation area and extent, which determines the effectiveness of the treatment.
However, according to the operation requirement, the distance between two adjacent ablation probes in the treatment operation is generally controlled to be between 1.0cm and 4.0cm, so as to avoid residual focus or influence on the treatment effect due to voltage abnormality, and the random movement of the ablation probes after the needle penetration can cause potential damage to the patient body, so that the position fixing of the ablation probes in the operation and the measurement of the needle distance are controlled to be an important factor for determining the operation effect.

The device is mainly used for carrying out multi-angle needle insertion positioning and fixing on the ablation probe in percutaneous tumor ablation operation and simultaneously measuring the distance between the ablation probes. When the method is specifically used, the number, the needle inserting angle and the position of the ablation probes required to be used and the interval value between the ablation probes are estimated in advance according to an ablation plan; next, one of the first positioning rings 40 is centripetally rotated around the central positioning disk 10 along the first annular track 30, and finally stopped at a position opposite to the first positioning mark 51 of the first inner ruler 50, and the positioning seat 160 is subjected to plane rotation, and the positioning tube 170 swings on the positioning seat 160, so that the needle inlet angle of the first ablation probe is met, and therefore the position of the first positioning ring 40 serving as a contact pin of the first ablation probe can be determined; then, the needle pitch value determined by the previous array plan is further set, at least one other first positioning ring 40 in the first annular track 30 is centripetally rotated around the central positioning disk 10 and stopped at the position of the first inner digital mark 52 corresponding to the first inner ruler 50, then the positioning seat 160 is subjected to plane rotation, the positioning tube 170 swings relative to the positioning seat 160, and the needle inserting angle of the second ablation probe is met, so that the needle inserting position of the second ablation probe can be determined, and the like.

It will be appreciated that the pre-operative needle placement plan determines that two ablation probes are required and that the needle spacing value of the two ablation probes is controlled to be 1cm. The first internal positioning mark 51 and the first internal digital mark 52 are preset on the surface of the first internal ruler 50 by printing, pasting, etc., the first internal digital mark 52 can be displayed with the numbers "1,2, etc., and for distinguishing, the first internal positioning mark 51 adopts a solid black triangle shape, and the first internal digital mark 52 adopts a hollow triangle shape. At this time, two first positioning rings 40 are installed in the first annular track 30, one of the positioning rings is rotated to align with the first positioning mark 51, and then the other first positioning ring 40 is rotated to align with the first positioning mark 51 with the number "1", so that the distance between the two ablation probes to be inserted can be determined to be 1cm.

At this time, the outer peripheral edges of the first inner ruler 50 and the central positioning disk 10 can tightly abut against the first positioning ring 40, so that the first inner ruler 50 can be stably mounted on the surface of the central positioning disk 10 without being displaced along the radial direction under the limiting action of the first positioning ring 40, and the positioning accuracy of the ablation probe is affected.
Further, at least two first inner digital marks 52 are arranged on both sides of the first inner positioning mark 51 at equal intervals, and form a first inner space mark group. Namely, the first internal digital mark 52 representing different needle spacing values in a symmetrical relation is set in both clockwise and anticlockwise directions with the first internal positioning mark 51 as a starting point, when positioning and measuring the ablation probe, the first positioning ring 40 can be allowed to rotate around any direction, the flexibility of the device is improved, and the first positioning ring 40 can stop on the skin surface of a larger area of operation area due to the rotation around both clockwise and anticlockwise directions, so that the positioning and needle spacing measuring capability can be greatly improved.
