Description

Technical Field

[0001] This utility model belongs to the field of medical equipment technology, and in particular relates to an electrosurgical pen with smoke removal function. Background Technology

[0002] When an electrosurgical pen is used, it produces a large amount of smoke, which affects the cutting or electrocoagulation effect. Therefore, there is an urgent need to configure a device that can attract the smoke. In minimally invasive surgery, inserting an additional smoke suction device requires additional openings, which is inconvenient for patients. Therefore, many electrosurgical pens have smoke extraction ducts inside for smoke removal, but this greatly increases the structural complexity and can easily contaminate the internal space.

[0003] For example, a Chinese utility model patent discloses a surgical electrosurgical unit with smoke suction function [Application No.: CN202121939352.5]. This utility model includes an electrosurgical head and an electrosurgical handle, with the head fixedly mounted on the handle. The handle includes a hollow smoke extraction tube, a circuit board, a fixing structure, and a tail interface. The front end of the hollow smoke extraction tube has a smoke extraction opening, and the electrosurgical head is fixed by the fixing structure at the front of the hollow smoke extraction tube. This utility model can attract smoke, ensuring a clear surgical field of vision, increasing surgical safety, reducing smoke pollution, and protecting the health of operating room personnel. The smoke extraction tube opening is positioned appropriately, facilitating smoke extraction without being blocked by coagulated blood and tissue debris. The electrosurgical head passes through the hollow smoke extraction tube, essentially transforming the insulating tube of an existing electrosurgical unit without a suction tube into a smoke extraction tube. This gives the electrosurgical unit a smoke extraction function without changing its basic form, while minimizing obstruction of the surgical field of vision. Its structure is simple, easy to manufacture, and suitable for mass production.

[0004] Although the invention draws in smoke through a built-in hollow smoke extraction tube, it requires a separate suction device and the interior is easily contaminated and difficult to clean. Summary of the Invention

[0005] To address the aforementioned problems, this utility model provides an electric knife pen with smoke removal function, comprising a housing assembly and an electric knife assembly; the electric knife assembly includes an electric knife rod with the blade protruding from one end of the housing assembly; it also includes a negative ion electrode, and the housing assembly has a negative ion chamber near the blade protruding from the negative ion chamber.

[0006] Preferably, the outer casing assembly includes a base and an upper cover. The base has a first bending portion, and the upper cover has a second bending portion. The upper cover and the base are fixedly installed so that the first bending portion and the second bending portion fit into the internal space to form a negative ion chamber.

[0007] Preferably, the first and second bends are provided with grooves, which form negative ion chambers symmetrically when the base and the upper cover are fixedly installed.

[0008] Preferably, the first bend and the second bend are each provided with at least two grooves.

[0009] Preferably, the base includes a mounting post, and the upper cover has a mounting cavity for accommodating the mounting post.

[0010] Preferably, the negative ion electrode includes an insulated wire conduit and a wire located inside the insulated wire conduit, with the wire exposed outward from the insulated wire conduit on the side of the chamber near the blade tip.

[0011] Preferably, the upper cover is provided with at least one button receiving groove for accommodating a button.

[0012] Preferably, the upper cover is provided with a compression seat, and the base is provided with a pressure-bearing base. After the compression seat and the pressure-bearing base are put together at the first bend and the second bend, they jointly clamp the insulated wire hose.

[0013] Compared with existing technologies, the advantages of this utility model are: This invention simplifies the smoke removal process by placing a negative ion electrode near the tip of the electric scalpel, which carries negative ions to the smoke generated during operation, making it easier for the smoke to settle. This saves material costs and avoids the problem of traditional smoke extraction tubes polluting the internal space of the electric scalpel. Attached Figure Description

Detailed Implementation

[0015] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0016] This utility model is an electric knife pen with smoke removal function, such as Figure 1-2As shown in Figure 4, the device includes a housing assembly 1 and an electrosurgical assembly 2. The electrosurgical assembly 2 includes an electrosurgical rod 21, the tip 211 of which extends out of one end of the housing assembly 1. It also includes a negative ion electrode 3. The housing assembly 1 has a negative ion chamber 11 for accommodating the negative ion electrode 3 at one end near the tip 211, and one end of the negative ion electrode 3 extends out of the negative ion chamber 11.

[0017] In this invention, the negative ion electrode 3 is energized before the electric knife rod 21 cuts. The negative ion electrode releases electrons, causing the smoke generated near the cutting point of the knife head 211 to carry negative ions, thereby guiding it to settle and preventing it from floating for a long time.

[0018] Specifically, for ease of disassembly and assembly, such as Figure 2 As shown, the outer shell assembly 1 includes a base 12 and an upper cover 13. The base 12 is provided with a first bending portion 121, and the upper cover 13 is provided with a second bending portion 131. The upper cover 13 and the base 12 are fixedly installed so that the first bending portion 121 and the second bending portion 131 fit into the internal space to form a negative ion chamber 11.

[0019] Specifically, such as Figure 2 , 3 As shown, the aforementioned internal space is formed such that the first bending portion 121 and the second bending portion 131 are provided with grooves 4, as... Figure 5 As shown, the groove 4 forms a negative ion chamber 3 symmetrically on the top and bottom when the base 11 and the upper cover 12 are fixedly installed.

[0020] Furthermore, the first bending portion 121 and the second bending portion 131 are each provided with at least two grooves 4 to embed more negative ion electrodes 3 for better attraction.

[0021] Preferred, such as Figure 2-3 As shown, the base 12 includes a mounting post 122, and the upper cover 13 is provided with a mounting cavity 132 for accommodating the mounting post 122. The base 12 and the upper cover 13 are connected and fixed through the cooperation of the mounting post 122 and the mounting cavity 132.

[0022] Specifically, such as Figure 2 As shown, the negative ion electrode 3 includes an insulated wire hose 31 and a wire 32 located inside the insulated wire hose 31. The wire 32 is exposed from the insulated wire hose 31 to the outside of the chamber near the blade head 211 to release negative ions.

[0023] Preferred, such as Figure 2 As shown, the upper cover 13 is provided with at least one button receiving groove 133 for accommodating the operation button of the electric knife pen.

[0024] Preferably, in order to standardize wiring, such as Figure 2 ,3 As shown, the upper cover 13 is provided with a compression seat 134, and the base 12 is provided with a pressure-bearing base 123. After the compression seat 134 and the pressure-bearing base 123 are attached to the first bend 121 and the second bend 131, they jointly clamp the insulated wire hose 31.

[0025] The working principle of this embodiment is as follows: the outer shell assembly 1, consisting of the base 12 and the upper cover 13, facilitates gradual installation. During installation, the electric knife assembly 2 and the button are first placed on the base 12. Insulated flexible conduit 31 is pre-embedded on both sides of the base 12 and embedded along the groove of the base 12, with the portion extending out of the groove exposing the internal wires 32. To better release negative ions, such as... Figure 1 As shown, the wire 32 can be composed of very fine wires aggregated together and dispersed and exposed at one end near the cutter head 211. After the above components are installed, the upper cover 13 is pressed down, the mounting post 122 is inserted into the mounting cavity 132, and the groove 4 on the first bend 121 of the base 12 and the second bend 131 of the upper cover 13 fits together to form a... Figure 5 The negative ion chamber 11 shown tightly secures the insulated flexible conduit 31 near the electric knife assembly 21. Simultaneously, the compression seat 134 and pressure-bearing base 123 within the base 12 and upper cover 13 also tightly press the insulated flexible conduit 31 upwards and downwards for further fixation. During use, before cutting with the electric knife rod 21, the wire 32 inside the insulated flexible conduit 31 is energized. A large number of negative ions (electrons) are released from the negative ion chamber 11 near the blade head 211. During cutting, the generated smoke carries these negative ions and settles instead of floating, achieving a better smoke removal effect.
