Description

Technical Field

[0001] This utility model belongs to the field of medical equipment technology, and in particular relates to a plasma surgical electrode. Background Technology

[0002] Plasma surgical electrodes work by ionizing saline solution surrounding the electrode to form a plasma layer. The high-energy particles in the plasma have sufficient energy to break the chemical bonds between tissue molecules, causing tissue cells to decompose and vaporize, thus achieving the cutting and ablation of soft tissue. Traditional monopolar plasma surgical electrodes have a simple structure but are prone to electrical or thermal burns, especially when using high-power electrosurgical units. Therefore, bipolar electrodes are currently the mainstream choice. The most common types are pin-type and wire-type plasma surgical electrodes. Pin-type electrodes have disadvantages such as requiring a separate connecting wire and requiring a long preparation time. Wire-type plasma surgical electrodes consist of two tubes with an elliptical cross-section, which cannot be well sealed, and the dual-tube design makes it easy for dirt and grime to accumulate in the recessed areas of the two tubes, hindering cleaning and sterilization.

[0003] For example, a Chinese invention patent application discloses a plasma high-frequency integrated surgical device [Application No.: 202322854747.0]. This invention includes electrode pads, an insulating coating, electrode rods, a handle, a coagulation button, a cutting button, cables, and a high-frequency generator. The electrode pads are connected to the handle via the electrode rods; the electrode pads are connected to the high-frequency generator via cables; the coagulation button and the cutting button are used to control the electrode pads; the electrode pads have at least two opposing cutting edges, one of which has an insulating coating on both sides forming a slit at the location of the cutting edge, while the other cutting edge does not have a slit formed by the insulating coating on both sides.

[0004] Although this invention achieves low-temperature plasma cutting and high-frequency electrode coagulation on a single electrode, which helps improve surgical safety, reduce surgical complexity, and save surgical time, it still does not solve the problems caused by monopolar surgical electrodes. Summary of the Invention

[0005] The purpose of this invention is to address the above-mentioned problems by providing a plasma surgical electrode. By using a conductive outer tube as part of the current circuit, it eliminates the problem of easy burns caused by using the human body as one electrode in traditional monopolar plasma surgical electrodes, while also achieving the advantages of simple structure and easy cleaning and assembly of monopolar electrodes.

[0015] Preferably, it also includes an insulating tube sleeved around the outer tube. Compared with the prior art, the advantages of this utility model are: This invention simplifies the structure and makes installation and cleaning easier by setting an outer tube as part of the current loop and changing the current flow of the outer tube through a conductive transfer structure so that the positive and negative poles are connected through the same socket set.

Detailed Implementation

[0017] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0018] This utility model is a plasma surgical electrode, including a socket set 1, an internal insulating conductive structure 2, an outer tube 3 sleeved outside the internal insulating conductive structure 2, and an electrode head 4. The socket set 1 leads out a positive electrode line 11 and a negative electrode line 6. The outer tube 3 is made of conductive material. It also includes a conductive transition structure 5. The current flows from the positive electrode line 11 through the internal insulating conductive structure 2 to the electrode head 4 to stimulate saline, and then flows back through the outer tube 3 to the conductive transition structure 5 to lead into the negative electrode line 6.

[0019] When using this utility model, such as Figure 1-4 As shown, the current flows through the positive wire 11 of the socket set 1 from the internal insulating conductive structure 2 to the position of the electrode head 4. The conductive outer tube 3 provided in this utility model is insulated from the internal insulating conductive structure 2. After the current is released at the electrode head 4, it is conducted through physiological saline and returned from the outer tube 3. Under the guidance of the conductive transition structure 5, it flows back to the negative wire 6 led out from the socket set 1, completing the complete current return process of the bipolar plasma electrode.

[0020] Specifically, such as Figure 3 , 4 As shown, the conductive transfer structure 5 includes an electrode plate 51, and the negative electrode line 6 and the outer tube 3 are in conductive contact with the electrode plate 51.

[0021] Preferred, such as Figure 4 As shown, the internal insulating conductive structure 2 includes an insulating inner tube 21 and a wire 22. The wire 22 is located inside the insulating inner tube 21. The insulating inner tube 21 passes through the outer tube 3 and has a 90-degree bend structure 211 at one end extending out of the outer tube 3. This structure is mainly to cooperate with the aforementioned conductive transition structure 5 to redirect the current direction so that the positive and negative poles can be connected simultaneously through the socket set 1.

[0022] Preferred, such as Figure 4 As shown, the electrode plate 51 includes a contact hole 511, and the outer tube 3 penetrates the electrode plate 51 and contacts the inner wall of the electrode plate 51 to achieve the function of conducting electricity.

[0023] Furthermore, in order to further solidify, such as Figure 2-4 As shown, it also includes a line plug assembly 7 and a negative limit sleeve 8. One end of the negative electrode line 6 is inserted into the negative limit sleeve 8. The line plug assembly 7 limits the negative electrode line 6 to make stable contact with the electrode plate 51 by limiting the negative limit sleeve 8, thereby achieving current conduction.

[0024] Furthermore, the wire plug assembly 7 includes a wire plug cap 71 and a wire plug 72, and the electrode plate 51 is clamped and fixed by the wire plug cap 71 and the wire plug 72.

[0025] Furthermore, in order to expose electrode head 4, such as Figure 4 As shown, one end of the outer tube 3 includes a pre-expansion space 31 that gradually increases in radius toward the electrode head 4.

[0026] Furthermore, the insulating inner tube 21 branches in the pre-expansion space 31, and the wire 22 extends out at the end of the branch and is connected as a whole. The part of the wire 22 exposed to the outside constitutes the electrode head 4.

[0027] Furthermore, to extend the conductive range of the corresponding outer tube 3, a conductive branch tube 9 is provided. The conductive branch tube 9 is wrapped around the outside of the branch point of the insulating inner tube 21 and makes conductive contact with the outer tube 3.

[0028] Furthermore, it also includes an insulating tube 10 sleeved outside the outer tube 3 to achieve insulation between the overall electrode assembly and external instruments (such as endoscopes).

[0029] The working principle of this utility model is as follows: The positive wire 11 led out from the socket set 1 is connected to the wire 22 inside the insulating inner tube 21. Then, the insulating inner tube 21 and the wire 22 are forked at one end. A part of the wire 22 extends from the head of the forked insulating inner tube 21 and they are connected to each other to form an electrode head. Then, a conductive outer tube 3 is put on the insulating inner tube 21. At the fork of the electrode head 4, a conductive forked tube 9 is used to make conductive contact with the outer tube 3 to extend the conductive distance. The outer tube conducts downward through the contact electrode plate 51. The electrode plate 51 achieves stable contact with the negative wire 6 through the negative limit sleeve. The insulating inner tube 21 also changes direction by the bending structure 211 after the outer tube 3 passes through the electrode plate 51 to connect the wire 22 and the positive wire 11, so as to guide the positive and negative poles to the same socket. Finally, the negative limit sleeve 8 and the electrode plate 51 are installed and clamped with the wire plug cap 71 and the wire plug 72 to form the final limit. The current flows through the positive wire 11 of the socket set 1 from the internal insulating conductive structure 2 to the position of the electrode head 4, where it releases energy to excite the saline solution. After being conducted through the saline solution to the conductive branch tube 9, it flows back from the outer tube 3 and, guided by the conductive transfer structure 5, flows back to the negative wire 6 led out from the socket set 1, completing the complete current return process of the bipolar plasma electrode.

Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0031] Although this document frequently uses terms such as socket set 1, internal insulating conductive structure 2, outer tube 3, electrode head 4, conductive adapter structure 5, negative wire 6, wire plug assembly 7, negative limit sleeve 8, electrode plate 51, insulating inner tube 21, wire 22, bending structure 211, contact hole 511, wire plug cap 71, wire plug 72, pre-expansion space 31, conductive branch tube 9, insulating tube 10, and positive wire 11, the possibility of using other terms is not excluded. The use of these terms is merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any additional limitation would contradict the spirit of this utility model.
