[0024] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.
[0025] This utility model embodiment provides an electric knife pen, such as Figure 1 As shown, the electric pen includes a grip body 10 and a light guide structure 20. The front end of the grip body 10 is formed with a blade 30, and a light outlet hole 11 is provided on the side of the grip body 10 near the blade 30. The light guide structure 20 is used to connect the grip body 10 and an external light source, to conduct the light from the external light source into the grip body 10, and to project the light outward through the light outlet hole 11.
[0026] This application features a grip body 10 and a light guide structure 20. The grip body 10 has a blade 30 at its front end, and a light-emitting hole 11 is provided on the side of the grip body 10 near the blade 30. The light guide structure 20 is used to connect the grip body 10 and an external light source. When illumination is needed, the external light source can be connected to the light guide structure 20, which will guide the light from the external light source into the grip body 10 and project the light outward through the light-emitting hole 11 to achieve illumination. When illumination is not needed, there is no need to connect to an external light source. Therefore, the electric pen is lighter when illumination is not required, improving the comfort and flexibility of operation.
[0027] In this embodiment, reference Figure 1 , Figure 2 and Figure 4The grip body 10 has a light guide channel 40 communicating with the light emission hole 11. The light guide structure 20 includes an optical fiber 21. One end of the optical fiber 21 is used to connect to an external light source, and the other end extends into the light guide channel 40 and is positioned close to the light emission hole 11. When illumination is needed, one end of the optical fiber 21 is connected to the external light source. The light emitted by the external light source is conducted into the optical fiber 21, and after being conducted through the optical fiber 21 to the light guide channel 40, the light is projected outward from the light emission hole 11 to provide illumination, making it convenient to use. When illumination is not needed, one end of the optical fiber 21 is suspended, and there is no need to connect to an external light source. The overall weight of the electric sharpener is small, making it comfortable and flexible to operate.
[0028] When the fiber optic cable 21 is connected to an external light source, such as the light outlet of a flashlight, the fiber optic cable 21 can be fixed relative to the external light source, eliminating the need for handheld operation. Users can hold the main body of the electrosurgical pen by hand to perform surgical procedures.
[0029] In another embodiment, the gripping body 10 is provided with a light guide channel communicating with the light emission hole 11. The light guide structure 20 includes an optical fiber 21, one end of which is used to connect to an external light source, and the other end is used to connect to the entrance of the light guide channel. The optical fiber 21 can also conduct light from the external light source into the light guide channel of the gripping body 10 and project it outward from the light emission hole 11 to provide illumination. In this embodiment, the light guide channel can be a channel that leads directly to the light emission hole 11.
[0030] Using fiber optic cable 21 to transmit light can effectively transmit optical signals with almost no loss of light energy, resulting in higher signal transmission quality. Furthermore, it is non-conductive, thus providing higher safety performance.
[0031] In other embodiments, the light guide structure 20 may also be a light guide strip, an optical waveguide, or other structural component that can transmit light, and may also transmit light from an external light source into the holding body 10.
[0032] refer to Figure 1 , Figure 3 and Figure 4 In this embodiment, an inclined channel 50 is provided at the entrance of the light guide channel 40. The opening size of the inclined channel 50 gradually decreases from the entrance inward. The optical fiber 21 passes through the inclined channel and extends to the light guide channel 40.
[0033] By setting an inclined channel 50, the size of its opening gradually decreases from the entrance to the inside. When installing the optical fiber 21, the optical fiber 21 can gradually pass through the smaller opening through the larger opening and extend to the light guide channel 40. This can effectively guide the optical fiber 21 to connect to the entrance of the light guide channel 40 or extend into the light guide channel 40, which facilitates the installation of the optical fiber 21.
[0034] Further, refer to Figure 2 and Figure 3The electric scalpel also includes a signal line 60, a signal plug 70, and a circuit board 80. The signal line 60 is electrically connected to the signal plug 70 and the circuit board 80 respectively. The sum of the wire diameters of the signal line 60 and the fiber optic cable 21 is adapted to the minimum opening size of the inclined channel 50. The circuit board 80 is located inside the holding body 10 and is electrically connected to the scalpel head 30.
[0035] The signal plug 70 can be connected to external high-frequency surgical equipment to receive relevant signals from the high-frequency surgical equipment. The electrosurgical pen, in conjunction with the high-frequency surgical equipment, replaces the mechanical scalpel for tissue cutting. It heats the tissue through high-frequency, high-voltage current generated at the effective electrode tip when it contacts the body, achieving tissue separation and coagulation, thus achieving the purpose of cutting and hemostasis. The signal line 60 transmits signals to the circuit board 80, enabling the blade head 30 to perform its corresponding functions. Because the combined diameter of the signal line 60 and the fiber optic cable 21 matches the minimum opening size of the inclined channel 50, inserting the signal line 60 and the fiber optic cable 21 achieves a relative seal within the light guide channel 40 of the holding body 10, preventing light leakage and providing better illumination.
[0036] Further, refer to Figure 1 and Figure 3 , Figure 4 The electrosurgical pen also includes an electrocoagulation operation switch 90 and an electrocutting operation switch 100, both of which are electrically connected to the circuit board 80.
[0037] The electrocoagulation operation switch 90 controls the electrocoagulation function of the electrosurgical pen, causing the corresponding biological tissue to coagulate. The electro-cutting operation switch 100 controls the electro-cutting function of the electrosurgical pen, enabling the cutting of biological tissue. By electrically connecting the electrocoagulation operation switch 90 and the electro-cutting operation switch 100 to the circuit board 80, users can easily switch the working mode of the electrosurgical pen to meet different operational needs.
[0038] Furthermore, the gripping body 10 is provided with a first mounting hole 12 and a second mounting hole 13. The electrocoagulation operation switch 90 passes through the first mounting hole 12 and is exposed on the gripping body 10, and the electrocution operation switch 100 passes through the second mounting hole 13 and is exposed on the gripping body 10.
[0039] By providing the first mounting hole 12 and the second mounting hole 13, the installation of the electrocoagulation operating switch 90 and the electro-cutting operating switch 100 is convenient. Furthermore, the exposed gripping body 10 of both switches helps users quickly locate the corresponding operating switch. To further facilitate user identification of the two operating switches, they can be distinguished by color, for example, the electrocoagulation operating switch 90 could be set to blue and the electro-cutting operating switch 100 to yellow. Alternatively, the two operating switches can be set to different shapes for identification.
[0040] refer to Figure 3 and Figure 4 In this embodiment, the electric knife pen also includes a sleeve 110, a connecting wire (not shown) and a blade 120 integrally formed with the blade head 30. The sleeve 110 is fixed inside the holding body 10 and sleeved around the outer periphery of the blade 120. One end of the connecting wire is electrically connected to the circuit board 80, and the other end passes through the sleeve 110 and is electrically connected to the blade 120.
[0041] By setting the sleeve 110, the blade 120 can be fixed inside the grip body 10, thereby fixing the blade head 30 and preventing the blade head 30 from shaking.
[0042] The integrated design of the cutting head 30 and the cutting body 120 ensures a more secure connection between them, reducing work interruptions or safety issues caused by loosening or detachment. The integrated design also improves the precision and stability of the cutting head 30, making cutting or electrocoating operations more refined and accurate. Furthermore, the integrated design is generally more durable, reducing wear and damage between components and extending the lifespan of the electrosurgical pen.
[0043] Furthermore, a perforation can be provided on the sleeve 110, through which the optical fiber 21 of the light guide structure 20 can pass and approach the light outlet 11.
[0044] refer to Figure 1 In this embodiment, the electric knife pen also includes a protective sleeve 130, which can be fitted onto the outer periphery of the blade head 30.
[0045] By providing a protective sleeve 130, when the electric razor is not in use, the protective sleeve 130 can be placed around the outer periphery of the blade head 30. The protective sleeve 130 helps keep the blade head 30 clean and hygienic, preventing the blade head 30 from being contaminated by external factors or bacteria, thus protecting the blade head 30. It also makes the razor head 30 easier to carry and store, preventing damage to the blade head 30 or other items, and facilitating the transportation and storage of the electric razor. It can reduce wear and damage to the blade head 30, extend the service life of the blade head 30, and maintain the sharpness and effectiveness of the blade head 30. It effectively protects the blade head 30 and reduces the risk of accidental cutting or punctures.
[0046] This utility model embodiment also provides an electric scalpel pen system. The electric scalpel pen system includes a flashlight and the aforementioned electric scalpel pen, wherein the light guide structure 20 of the electric scalpel pen is connected to the light outlet of the flashlight.
[0047] The electric razor pen system of this application is configured with a grip body 10 and a light guide structure 20. The front end of the grip body 10 is formed with a blade 30. A light outlet 11 is provided on the side of the grip body 10 near the blade 30. The light guide structure 20 is used to connect the grip body 10 and the light outlet of a flashlight. When illumination is needed, the light outlet of the flashlight can be connected to the light guide structure 20. The light guide structure 20 conducts the light from the flashlight into the grip body 10 and projects the light outward through the light outlet 11 to achieve illumination. When illumination is not needed, there is no need to connect to the light outlet of the flashlight, and the flashlight can be removed. Therefore, the electric razor pen is lightweight when illumination is not needed, improving the comfort and flexibility of operation.
[0048] In this embodiment, a flashlight is used as the light source. The flashlight's light outlet is connected to the light guide structure 20. The flashlight can be turned on and off by operating the switch button on the flashlight, thereby controlling the on and off of the electric pen's illumination. The operation is very convenient. The flashlight is small, lightweight, and easy to carry, and its light can be directed to the specific area that needs illumination, being directionally conducted into the light guide structure 20, resulting in better lighting effects.
[0049] When the light guide structure 20 uses an optical fiber 21, one end of the optical fiber is connected to the light outlet of the flashlight.
