Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a plasma electrode. Background Art

[0002] In the early 21st century, plasma was used in electrosurgery, and its various advantages gradually became apparent. Plasma can be divided into high-temperature plasma and low-temperature plasma based on the relative temperature of the charged particles. Plasma radiofrequency uses energy generated by bipolar electrodes to convert the electrolyte between the radiofrequency blade and the tissue into a plasma film. After being accelerated by the electric field, the charged particles in the plasma transfer energy to the tissue, dissociating the molecular bonds that make up the cells in the target tissue. This causes the cells in the target tissue to disintegrate into molecular units, decomposing them into carbohydrates and oxides. This causes coagulative necrosis of the tissue, resulting in the shedding of necrotic tissue or scarring and contraction, creating a tissue cutting effect.

[0003] The emitter of existing RF electrode products is often made of high-temperature-resistant and biocompatible metal. It can be a single-piece, long strip or a sheet of metal with a ball-shaped, fixed (and conductive) head. The front end of the emitter serves as the anode during surgery, directly stimulating the plasma, while the back end connects to the lead wire. The return electrode is typically a stainless steel tube, with ceramic or high-temperature-resistant polymer components used as the physical insulation between the two.

[0004] When using radiofrequency electrodes during surgery, the surgeon holds the radiofrequency electrodes and operates on the surgical wound. However, the depth of the surgical wound of each patient is different. The doctor often needs to perform deep and pulling movements during the operation to continuously treat the wound.

[0005] During the operation, the surgeon does not only use radiofrequency electrodes for treatment, but also performs other treatments. The operation time varies in length, which is an important test of the doctor's mental and physical strength. When the doctor holds the radiofrequency electrode to treat the wound, especially when deep into the wound, the working method of holding the radiofrequency electrode in the hand will inevitably cause shaking and slipping due to sweating during the high concentration process. In addition, when going deep or pulling out, it will drive various wires and tubes to make corresponding movements, affecting the treatment work.

[0006] Therefore, we propose a radio frequency electrode to solve the above problems. Utility Model Content

[0007] The purpose of the present invention is to provide a plasma electrode to solve the problems raised in the above background technology.

[0008] To achieve the above objectives, the present invention provides the following technical solutions:

[0009] A plasma electrode comprises a hollow tube for inserting the electrode and a designed installation pipeline, wherein the right end of the outer ring of the hollow tube is fitted with an end handle shell, the left end of the outer ring of the hollow tube is fitted with a front handle shell, a support handle is fixedly connected to the outer wall of the hollow tube, and a pressing handle is fixedly connected to the outer wall of the end handle shell.

[0010] Preferably, the right side of the front handle shell and the left side of the end handle shell are connected and fixed by a connecting rod.

[0011] Preferably, the top and bottom of the inner wall of the end handle shell and the front handle shell are both provided with limiting sliding grooves.

[0012] Preferably, the top and bottom of both ends of the outer wall of the hollow tube are integrally fixedly connected with limiting sliding blocks adapted to the limiting sliding grooves.

[0013] Preferably, a cutter head rod is fixedly mounted on the left end surface of the front handle shell, and an electric cable and a suction water pipe are installed through the right end surface of the end handle shell.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] The utility model provides a plasma electrode technical solution:

[0024] Example:

[0025] like Figure 1 As shown, the radio frequency electrode of the present technical solution mainly includes a hollow tube 1 for inserting the electrode and designing the installation pipeline. The end handle shell 2 and the front handle shell 3 are respectively installed in a sleeve-type manner at both ends of the outer circle of the hollow tube 1. A support handle 6 is fixedly connected to the outer wall of the hollow tube 1, and a pressing handle 7 is fixedly installed on the outer wall of the end handle shell 2.

[0026] Among them, such as Figure 1 and Figure 2 As shown, the end handle housing 2 and the front handle housing 3 are butt-jointed on opposite sides via a connecting rod 12 .

[0027] Among them, such as Figure 3 As shown, limiting grooves 4 are provided on the inner walls of the end handle housing 2 and the front handle housing 3 .

[0028] Among them, limiting sliding blocks 5 adapted to the limiting sliding grooves 4 are fixedly installed at both ends of the outer wall of the hollow tube 1.

[0029] Among them, such as Figure 1 and Figure 2 As shown, a cutter head rod 9 is installed on the left end of the front handle housing 3, and a suction water pipe 11 and a cable 10 are installed through the right end surface of the end handle housing 2.

[0030] Among them, such as Figure 2 As shown, a chamfered structure 8 is provided on the left end face of the hollow tube 1 , and the left side of the outer wall of the hollow tube 1 is tangent to the inner wall of the front handle housing 3 .

[0031] The length of the limiting groove 4 is shorter than the length from the limiting slider to the end of the hollow tube 1. The main purpose of this design is to ensure that the end of the hollow tube 1 and the inner wall of the handle shell are always sealed when the end handle shell 2 and the front handle shell 3 are moving, that is, the liquid can only enter the inner cavity of the hollow tube 1 and will not overflow from other places.

[0032] In this embodiment, when using this technical solution for surgery, the cable 10 and the suction pipe 11 are first connected and installed with the external equipment. Then the surgeon can directly hold the support handle 6 and the pressing handle 7 to perform the retraction work, that is, the blade rod 9 is inserted into the wound position for treatment. When the required depth is inconsistent, in order to avoid the handheld RF electrode from shaking easily when moving, the pressing handle 7 can be pressed directly by the fingers in the original position. The pressing handle 7 drives the end handle shell 2 to move along the radial direction of the hollow tube 1, and the connecting rod 12 drives the front handle shell 3 and the blade rod 9 to continuously penetrate the wound. Then, it is possible to directly operate the RF electrode blade to insert or pull out of the wound without moving the RF electrode in a fixed position, which effectively solves the problem of doctors shaking easily when they are mentally and physically exhausted after a long operation. At the same time, it also solves the problem that the RF electrode, which needs to be moved as a whole, easily affects the wound and the external pipes and wires.

[0033] Secondly, this technical solution does not adopt the working method of holding the handle of the radio frequency electrode by hand, which can effectively solve the problem of the existing technology that the hand holding method easily blocks the light and the line of sight of the auxiliary observation equipment.

[0034] It should also be noted that, in the description of this utility model, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to mechanical connections or electrical connections; they may refer to direct connections or indirect connections through an intermediate medium; and they may refer to internal communication between two components. Those skilled in the art will be able to understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0035] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
