[0002] Existing surgical electrode devices, such as Figure 1 As shown, in the manufacturing process, after one axial end of the metal rod 91 is positioned with the shoulder of the plastic wheel 92, the other end is threadedly connected with the metal wheel 93. In order to ensure reliable tightening between the metal wheel 93 and the metal rod 91, the metal wheel 93 is usually directly subjected to partial radial stamping so that the metal wheel 93 clamps the metal rod 91. However, direct partial radial stamping of the metal wheel 93 not only easily causes deformation of the metal wheel 93, but also easily causes axial offset between the metal wheel 93 and the metal rod 91. Utility Model Content

[0003] In view of this, the utility model provides an electrode connection structure and a surgical electrode device to solve the problem that the existing surgical electrode device not only easily causes deformation of the metal wheel during the manufacturing process, but also easily causes axial offset between the metal wheel and the metal rod.

[0011] Beneficial effect: The conical surface portion forms an interference fit with the conical surface groove during the process of tightening the locking wheel and the rod body thread. Since the dial wheel is made of plastic, the dial wheel will form a polymer micro-compression effect on the conical surface portion during this process, and as the thread is tightened, the locking and anti-slip effect of the dial wheel on the conical surface portion becomes stronger and stronger, thereby avoiding axial displacement between the locking wheel and the rod body; at the same time, the conical surface portion and the conical surface groove are plugged into each other and have an interference fit, and the polymer micro-compression effect of the dial wheel on the conical surface portion can form a seal between the dial wheel and the conical surface portion, thereby avoiding foreign matter from entering from the connection between the dial wheel and the locking wheel, and ensuring the insulation effect on the rod body.

[0061] It should be noted that please combine Figure 4 and Figure 6 As shown, since the dial wheel 20 is made of plastic material, during the process of threading the locking wheel 30 and the rod body 10, the cylindrical portion 312 can be gradually screwed into the cylindrical groove 212 under the drive of the locking wheel 30 and have an interference fit with the cylindrical groove 212. During this process, the dial wheel 20 will form a polymer micro-compression effect on the cylindrical portion 312, and as the dial wheel 20 is continuously screwed into the cylindrical portion 312, the locking and stopping area of ​​the cylindrical portion 312 becomes larger and larger, thereby avoiding axial deviation between the locking wheel 30 and the rod body 10; at the same time, through the cylindrical portion 312 and the cylindrical groove 212 has an interference fit, and the polymer micro-compression effect of the dial wheel 20 on the cylindrical surface portion 312 can form a seal between the dial wheel 20 and the cylindrical surface portion 312, avoiding the entry of foreign matter from the connection between the dial wheel 20 and the locking wheel 30, and further ensuring the insulation effect of the rod body 10; in this process, the conical surface portion 311 and the conical surface groove 211 are plugged into each other and have an interference fit, which can not only effectively avoid axial deviation between the locking wheel 30 and the rod body 10, but also form two seals, effectively ensuring the insulation effect of the rod body 10.
