example 1

[0042] Such as figure 1 and figure 2 As shown, the plug-in neutral electrode provided in this example is a unipolar plate, which mainly includes a sub-electrode 10 , an insulating shell 11 , and at least one conductive sheet 12 .

[0043] The interior of the sub-electrode 10 defines a chamber 13 with both ends open, and the chambers 13 are distributed along the extension direction of the sub-electrode 10 to form a hollow cylindrical sub-electrode 10 along the axial direction.

[0044] The insulating shell 11, whose main structure matches the cavity 13 of the sub-electrode 10, can be inserted into the cavity 13 defined by the sub-electrode 10 as a whole and extends therein; when inserted into the sub-electrode 10, the insulating shell The body 11 is able to close a port of the sub-electrode chamber.

[0045] The conductive sheet 12 is electrically connected to the sub-electrodes 10 and electrically connected to the outside, that is, to realize the electrical connection of th...

example 2

[0070] Such as Figure 4-Figure 6 As shown, the plug-in neutral electrode of this example is a bipolar plate, and its basic structure is the same as that of Example 1, and the same parts will not be repeated here.

[0071] The difference is that the neutral electrode of this example includes a first sub-electrode 20 and a second sub-electrode 21, both of which have the same structure and size, and are connected by an insulator 22 (for example, ceramics), so that the The chambers are connected.

[0072] Corresponding to the first sub-electrode 20 and the second sub-electrode 21 described above, the neutral electrode of the bipolar plate includes a first conductive sheet 23 and a second conductive sheet 24, and the first conductive sheet 23 and the second conductive sheet 24 are respectively connected to The first electrode 20 is electrically connected to the second electrode 21 .

[0073] see Figure 5 and Figure 6 , the first conductive sheet 23 in the plug-in neutral ele...

example 3

[0077] Such as Figure 7 and 8 As shown, this example provides a plug-in neutral electrode assembly, including the neutral electrode 40 in the above example and an electrical connector 30 detachably connected to the neutral electrode.

[0078] The electrical connector 30 in this example can be configured as a plug-type or a socket-type connector, respectively corresponding to the neutral electrode with the conductive strip accommodated in the insulating casing, and the neutral electrode with the conductive strip protruding from the insulating casing.

[0079] A plug-in piece is provided in the plug-type electrical connector, and the plug-in piece can be inserted into the insulating housing 11 to be electrically connected to the fixed end of the conductive piece.

[0080] The socket-type electrical connector is provided with a socket, and a plurality of conductive terminals are arranged in the socket. The conductive piece of the neutral electrode protrudes from the insulating ...

Abstract

The invention discloses an insertion-type neutral electrode and an electrode assembly. The electrode comprises at least one sub-electrode, an insulation shell and at least one conducting piece, a chamber with the two ends open is defined by the sub-electrodes, the insulation shell can be inserted into the chamber defined by the sub-electrodes, extends in the chamber and closes one end of the chamber of the sub-electrodes, and the conducting pieces are electrically and correspondingly connected to the sub-electrodes and are externally and electrically connected. The electrode assembly is composed of the insertion type neutral electrode and an electric coupler. The insertion type neutral electrode formed based on the scheme is simple in integral structure and can be safely reused, it is not required to carry out pretreatment on a contact face, and an operation method is simple.

Description

technical field [0001] The invention relates to a medical device technology, in particular to a neutral electrode technology for high-frequency surgery. Background technique [0002] High-frequency electric knife uses the principle of radio frequency to apply high-frequency and high-voltage current to the patient's part through the knife pen, and uses the tip of the knife pen to burn the contacted tissue instantly to achieve the effect of cutting or coagulation. The current applied to the human body must flow back to the high-frequency electrosurgical unit through the neutral electrode to form a complete circuit. [0003] As the neutral electrode for exporting current, the contact with the skin should be as uniform as possible to avoid skin burns caused by local high current density. In order to increase the contact area with the skin, the existing neutral electrodes are mostly adhesive structures. For this type of neutral electrodes, ensuring the surface viscosity is a nec...
