Embodiment 1

[0040] like Figure 1 to Figure 3As shown, a flexible plasma electrode is characterized in that it includes: a handle 1, a flexible knife rod 2 embedded in the end of the handle 1, and an electrode blade 3 arranged at the end of the flexible knife rod 1 away from the handle 1, The outer wall of the handle 1 is slidingly provided with a knife head opening and closing assembly 4; the flexible knife rod 1 can better adapt to the entry environment such as the human digestive tract. The electrode cutter head 3 ensures a stable plasma generation environment under the environment of physiological saline. The cutter head opening and closing assembly 4 is used to control the opening and closing of the electrode cutter head 3 .

[0041] The connector 401 on the cutter head opening and closing assembly 4 penetrates the side wall of the handle 1 and extends into the handle 1, and the connector 401 is slidingly connected with the handle 1. The inside of the handle 1 is a hollow structure ...

Embodiment 2

[0052] The structure of the flexible knife rod 2 and the electrode cutter head 3 in this embodiment is different from that in the first embodiment.

[0053] like Figure 4 to Figure 7 As shown, the flexible knife rod 2 is configured as a spring tube, and the pulling member 5 is located in the spring tube and connected to the electrode cutter head 3, and the outer diameter of the pulling member 5 matches the inner diameter of the spring tube. By setting the flexible knife rod 2 as a spring tube, it has certain elasticity and can be bent into various shapes, which can better adapt to the entry environment such as the human digestive tract.

[0054] The electrode cutter head 3 includes a first electrode 305 connected to the spring tube, and a second electrode 306 opposite to the first electrode 305. The first electrode 305 and the second electrode 306 are rotatably connected by a pin 307, and the second electrode 306 is connected to the second electrode 306. The puller 5 is conn...

Abstract

The invention discloses a flexible plasma electrode, and relates to the technical field of medical instruments. Comprising a handle, a flexible cutter bar embedded in the end of the handle and an electrode cutter head arranged at the end, away from the handle, of the flexible cutter bar, and a cutter head opening and closing assembly is arranged on the outer wall of the handle in a sliding mode; a connector on the cutter head opening and closing assembly penetrates through the side wall of the handle and extends into the handle, the connector is in sliding connection with the handle, a pulling piece is arranged on the connector in the axial direction of the handle, and the pulling piece penetrates through the flexible cutter bar and is connected with the electrode cutter head. The connector slides along the handle under the action of the tool bit opening and closing assembly and controls opening and closing of the electrode tool bit through the pulling piece. The flexible cutter bar can well adapt to approach environments such as the digestive tract of a human body; through the electrode tool bit, a stable plasma generation environment is ensured in a normal saline environment; the electrode cutter head is small in cut wound, cutting is more thorough, normal tissue can be reserved to a larger extent, and therefore the situation that the ablation range is too large is avoided.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a flexible plasma electrode. Background technique [0002] The description of the background technology of the present invention belongs to the relevant technology related to the present invention, and is only used to illustrate and facilitate the understanding of the content of the present invention. prior art on the filing date. [0003] At present, microwave or radiofrequency ablation is usually used for tumor treatment, but the ablation range is often too large, resulting in varying degrees of damage to healthy tissues around the tumor, which is not conducive to the ablation, cutting, and hemostasis of digestive tract tumors, and is not conducive to Peritoneal dialysis tubes and other pipelines left in the human body blockage and unblock tissue, which is not conducive to the treatment of thyroid (breast, liver, lung) nodules, tumor cutting, ablation and other problem...
