[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Example 1

[0025] Reference Figure 1-6A precisely positioned electrode probe comprises a probe body 1 for puncturing a patient, the handle end of the probe body 1 is connected to an external treatment device for providing pulse current through a wire, a movable frame 2 is clamped on the outer ring surface of the handle end of the probe body 1, a guide rod 3 is slidably connected in the lower body wall of the movable frame 2, a mounting plate 4 is fixed to the end of the guide rod 3 located at the handle end of the probe body 1, a ball head rod 5 is fixed to the end of the mounting plate 4 located at the handle end of the probe body 1, a ball head seat 6 is movably clamped at the ball head end of the ball head rod 5, and one side of the ball head seat 6 is opposite to the The ball end of the ball head rod 5 is connected to a locking column 7 through a thread, and the end of the ball head seat 6 away from the ball head rod 5 is connected to a clamping clip 9 through a universal rod 8. The universal rod 8 is a rod on the existing mobile phone holder that can be bent at will and maintain the bent shape after bending, and other rods that can maintain the bent shape after bending can also be selected. The clamping clip 9 is a spring clip that can be directly purchased on the market in the prior art, such as a spring clip, a G-type clip, an F-type clip, or a clip on a mobile phone holder, etc. It can also be other types of clips as long as it has the effect of convenient clamping. Example 2

[0026] Reference Figure 1-6 , when other parts are the same as those in Example 1, the difference between this embodiment and Example 1 is that:

[0027] An elastic limit block 10 is installed at one end of the mounting plate 4 close to the ball head rod 5 corresponding to the movable frame 2, and a matching card groove is provided on the lower wall of the movable frame 2 corresponding to the limit block 10. The setting of the limit block 10 can limit the movable frame 2, that is, before puncturing, the operator first moves the movable frame 2 to this point until the movable frame 2 is fixedly connected to the mounting plate 4 through the limit block 10, thereby preventing the movable frame 2 from driving the probe body 1 to move at will when the operator adjusts the puncture position and causing interference; the limit block 10 is provided at one end close to the movable frame 2 to The upper raised arc-shaped portion and the arc-shaped portion corresponding to the slot of the moving frame 2 are provided with a matching guide surface. The setting of the arc-shaped portion enables the limit block 10 to provide a certain degree of connection stability for the moving frame 2, and the setting of the guide surface facilitates the connection between the moving frame 2 and the limit block 10; a force rod 11 is slidably inserted at one end of the locking column 7 located outside the ball head seat 6, and spherical ends are provided at both ends of the force rod 11 for preventing falling off. The setting of the force rod 11 makes it easy for personnel to rotate the locking column 7, thereby facilitating personnel to control the connection state between the ball head rod 5 and the ball head seat 6.

[0028] Gripping surfaces 12 are provided on both sides of the movable frame 2, and the surfaces of the gripping surfaces 12 are provided with anti-slip grooves. The setting of the gripping surfaces 12 makes it convenient for personnel to control the movement of the movable frame 2 by hand, and then makes it convenient for personnel to puncture through the probe body 1; the interior of the ball head rod 5 is hollow, and the outer ring surface of the ball end of the ball head rod 5 is a frosted surface. Since the interior of the ball head rod 5 is hollow, it is convenient to reduce the weight of the ball head rod 5 and save resources used in the production of the ball head rod 5; a constraint block 13 is fixed to the end of the mounting plate 4 away from the ball head rod 5, and the adjacent end of the guide rod 3 is fixed to the outer wall of the constraint block 13. The setting of the constraint block 13 makes it convenient to block the guide rod 3, that is, to prevent the movable frame 2 from detaching from the guide rod 3.

[0029] Principle and advantages of use: During the use of the utility model, when the patient needs to undergo nanoknife surgery, that is, when the patient's tumor needs to be ablated, the personnel connects the probe body 1 to the treatment device through the wire at the handle end, and then fixes the universal rod 8 on the operating table or the anesthesia frame of the operating table and other components through the clamping clamp 9. At this time, the personnel can bend the universal rod 8 accordingly until the probe body 1 points to the patient's diseased part, that is, the rough positioning of the probe body 1 before puncture is achieved. At this time, the personnel loosen the locking column 7 and apply force to the mounting plate 4, that is, the mounting plate 4 rotates with the ball head seat 6 as the center through the ball head rod 5 until the pointing direction of the probe body 1 coincides with the pre-planned puncture point. At this time, the personnel can retighten the locking column 7 to make the ball head rod 5 and the ball head seat 6 fixedly connected, and further the personnel can push the movable frame 2 to move toward the patient until the needle end of the probe body 1 is inserted into Inside the patient's diseased area, then the external treatment equipment can perform corresponding treatment on the tumor in the patient's area through the needle end of the probe body 1, thereby completing the nanoknife surgery; in summary, during the use of this solution, the personnel bends the universal rod 8 and rotates the ball head rod 5, so that the probe body 1 can be easily pointed to the pre-planned puncture point, and then the personnel inserts the movable frame 2 into the patient's body by applying force with their hands, that is, during the puncture process, the personnel do not need to consider whether the puncture position is incorrect due to shaking of the probe body 1 due to hand shaking, that is, it can not only improve the positioning accuracy of the personnel during puncture, but also reduce the energy spent by the personnel during the puncture process, and because the universal rod 8 is connected to the operating table or other components through the clamping clamp 9, the present solution can flexibly adjust the installation position of the universal rod 8 according to the lesion when in use, that is, it solves the defect that the traditional solution has limitations on the diseased area when used.

[0030] It should be further explained that the setting of the limit block 10 can limit the movable frame 2, so as to prevent the movable frame 2 from driving the probe body 1 to move randomly when the personnel adjust the puncture position and cause interference; the setting of the arc portion enables the limit block 10 to provide a certain degree of connection stability for the movable frame 2, and the setting of the guide surface facilitates the clamping connection between the movable frame 2 and the limit block 10; the setting of the force rod 11 facilitates the personnel to rotate the locking column 7, so as to facilitate the personnel to control the connection state between the ball head rod 5 and the ball head seat 6; the setting of the grasping surface 12 facilitates the personnel to control the movement of the movable frame 2 by hand, and then facilitates the personnel to puncture through the probe body 1; a constraint block 13 is fixed to the end of the mounting plate 4 away from the ball head rod 5, and the adjacent end of the guide rod 3 is fixed to the outer wall of the constraint block 13. The setting of the constraint block 13 facilitates the blocking of the guide rod 3, that is, to prevent the movable frame 2 from detaching from the guide rod 3.
