A holding wire electrode comprising a metal electrode and a clip, wherein the clip comprises a V-shaped portion which is elastically deformable in the middle, a rear end of the V-shaped portion is connected to the lead wire, and two front ends of the V-shaped portion are connected to each other The so-called collet, the two so-called collets are symmetrically disposed, and the front end portions of the two solitary chucks are alternately overlapped, and the metal electrodes are connected to a C-shaped electrode piece on the inner side walls of the two so-called collet chucks, and the two C-shaped electrodes are connected The sheets are arranged in a staggered manner between the two solitary chucks, and the two C-shaped electrode sheets form a clamping electrode cavity.

The improvement of the above technical solution: the clamping electrode cavity of the two C-shaped electrode sheets is olive-shaped in a natural state, and when the two orphan-shaped chucks are pinched, the clamping electrode cavity becomes a circular or elliptical shape.

Further improvement of the above technical solution: the outer side walls of the two solitary chucks are provided with protrusions, and the protrusions are provided with strip edges.

Further improvement of the above technical solution: the wire connecting the two C-shaped electrode pieces The V-shaped portion in the middle of the clip is connected to the lead wire of the rear end of the V-shaped portion.

A further improvement of the above technical solution: a cylindrical character ring is arranged in the middle of the lead wire, and both ends of the character ring are flush with the lead wire.

A further improvement of the above technical solution: The clip is a one-piece structure of plastic injection molding.

Compared with the prior art, the invention has the following advantages and positive effects:

1. The clamping electrode cavity on the two C-shaped electrode sheets of the holding wire electrode of the present invention is olive-shaped in a natural state, and when the two orphan-shaped chucks are pinched, the clamping electrode cavity becomes a circular or elliptical shape. The columnar electrode to be clamped can be surrounded, and after the hand is released, the clamping electrode cavity becomes smaller in a natural state, the columnar electrode is clamped, the operation is very convenient, and the fixing and use are reliable, and it is not easy to be broken.

2. The shielded wire electrode of the present invention is connected with a medical standard or non-standard electrode for more reliable performance and is more compatible in clinical use.

3. A cylindrical character ring is arranged in the middle of the lead wire of the holding wire electrode of the present invention, and both ends of the character ring are flush with the lead wire. Due to the number of lead wires used in the middle of the wire, it is necessary to mark different symbols and colors. With a separate cylindrical character ring, the processing is convenient, the manufacturing cost is low, and the shape is beautiful.

detailed description

Referring to Figures 1 and 2, an embodiment 1 of a sheath wire electrode of the present invention includes a metal electrode and a clip. The clip comprises an intermediate elastically deformable V-shaped portion 2, the rear end of the V-shaped portion 2 is connected to the lead wire 1, and the two front ends of the V-shaped portion 2 are respectively a so-called collet 3 and a solitary collet 5, two orphans The collet 3, 5 are symmetrically arranged, and the front end portions of the two solitary chucks 3, 5 are alternately overlapped. The metal electrode includes two C-shaped electrode pieces 7 and C-shaped electrode pieces 4 on the inner side walls of the two isolated chucks 3, 5. The two C-shaped electrode pieces 4, 7 are relatively staggered between the two orphaned chucks 3, 5. Forming an empty Inside the cavity, the two C-shaped electrode sheets 4, 7 form a clamping electrode cavity. The clip is a one-piece structure of plastic injection molding.

In the natural state, the clamping electrode cavities of the two C-shaped electrode sheets 4, 7 are olive-shaped, and when the two C-shaped electrode sheets 4, 7 are pinched, the clamping electrode cavities become circular or elliptical.

On the outer side walls of the two orphan chucks 3, 5, bumps 6 are provided, and the bumps 6 are provided with strip edges.

The wires connecting the two C-shaped electrode sheets 4, 7 are connected to the lead wires 1 at the rear end of the V-shaped portion 2 via the V-shaped portion 2 in the middle of the clip.

Referring to Fig. 3, a second embodiment of the present invention is the same as that of the first embodiment. The difference is that a cylindrical character circle is arranged in the middle of the lead wire electrode lead wire 1, and the two ends of the character circle 8 are flush with the lead wire 1.
