Problems solved by technology

However, the existing low-temperature plasma electrodes are not strong enough to strip the tissue well, and need to be replaced with a puncture cannula to strip the articular disc, which increases the operation steps and prolongs the operation time
[0004] For the problems in related technologies, no effective solutions have been proposed yet

Embodiment 1

[0022] Such as Figure 1-2 As shown, the bipolar plasma surgical electrode for maxillofacial surgery according to the embodiment of the present invention includes a handle 7, and one side of the handle 7 is provided with an outer sheath 6, and the inside of the outer sheath 6 An outer layer cutter bar 5 is interspersed, and a middle sheath 4 is set inside the outer layer cutter bar 5, and a middle layer cutter bar 3 is interspersed inside the middle layer sheath 4, and the inside of the middle layer cutter bar 3 An inner sheath 2 is sheathed, and an inner electrode 1 matched with the knife handle 7 is interspersed inside the inner sheath 2 .

[0023] Let's talk about the specific settings and functions of the inner electrode 1, the inner sheath 2, the middle cutter bar 3, the middle sheath 4, the outer cutter bar 5 and the outer sheath 6.

[0024] Such as figure 1 As shown, when the device is in use, it is often necessary to peel off the joint disc downwards and backwards in...

Embodiment 2

[0026] Such as Figure 1-2 As shown, the inner electrode 1 is made of high-temperature-resistant metals such as molybdenum and tungsten or their alloys, and the ends are flat or sharpened. The middle cutter bar 3 and the outer cutter bar 5 are made of conductive The stainless steel tube is integrally formed, the inner sheath 2, the middle sheath 4 and the outer sheath 6 are made of non-toxic insulating materials such as PTFE, PVC, PE, and the outer knife rod 5 is A stainless steel pipe with good electrical conductivity, the inner electrode 1, the inner sheath 2, the middle cutter bar 3, the middle sheath 4, the outer cutter bar 5 and the outer sheath 6 The order is nested layer by layer, and the ends of each layer are misplaced and exposed to the lower layer. It is not difficult to see from the above design that the stability and safety of the equipment are increased, and the equipment is more hygienic.

[0027] In order to facilitate the understanding of the above-mentioned ...

Abstract

The invention discloses a dual-polarity plasma operation electrode for maxillofacial surgery. The dual-polarity plasma operation electrode comprises a handle. One side of the handle is provided with an outer layer sheath. An outer layer tool bar is inserted into the outer layer sheath. A middle layer sheath is sleeved with the outer layer tool bar. A middle layer tool bar is inserted in the middle layer sheath. An inner layer sheath is sleeved with the middle layer tool bar. An inner electrode matched with the handle is inserted in the inner layer sheath. The dual-polarity plasma operation electrode has the advantages that it is effectively ensured that dual-polarity plasma cutting and ablation are realized under the quite small diameter condition, precise excision and hole-forming ablation treatment can be conducted on minimal lesions in narrow positions where a conventional electrode cannot conduct operations, the requirement for postoperative wound attractive appearance of maxillofacial surgery patients is met since the wound formed by the smaller diameter of the electrode is smaller, and the dual-polarity plasma operation electrode can be used for stripping off soft tissue in maxillofacial surgery and can be used for conducting precise excision and hole-forming ablation treatment on the minimal lesions in narrow positions in maxillofacial surgery.

Description

technical field [0001] The invention relates to the medical field, in particular to a bipolar plasma surgical electrode for maxillofacial surgery. Background technique [0002] Low-temperature plasma technology has been widely used in otolaryngology and head and neck surgery, and has been noted to have good minimally invasive advantages. It can form a highly concentrated plasma vapor sheath around the electrode, break the molecular bonds that make up the target tissue cells at a relatively low temperature (40°C-70°C), and rapidly decompose the cells in the target tissue into carbohydrates and oxidize things. The range of the plasma steam sheath is extremely small, so its effect is precisely controlled at the tissue base where the electrode contacts, and has little impact on the surrounding and deep healthy tissue, so it has the advantages of less surgical trauma, less bleeding, less pain, and faster recovery features. [0003] This technology is rarely used in maxillofaci...
