[0002] The maxillofacial ionic electrosurgical unit is a commonly used medical device, mainly used for minimally invasive plastic surgery and repair of the maxillofacial region. By energizing the electrode tip of the ionic electrosurgical unit, a high-frequency current passes through the patient's facial tissue. Due to the resistance of the electrode tip, Joule heating is generated, causing cell water to vaporize (cutting) or protein to coagulate (hemostasis), thereby achieving operations such as dissolving fat, repairing depressed tissue, and improving facial laxity.

[0003] Currently, conventional electrosurgical units for ion surgery have limited functionality and are unable to provide auxiliary lighting sources, resulting in low visibility during surgery. This is especially true in maxillofacial tissue surgeries, where insufficient light may increase the risk of accidental injury to patients.

[0004] Therefore, existing technologies still need to be improved and developed. Utility Model Content

[0036] The invention will be further explained below with reference to the accompanying drawings and through description of the embodiments.

[0037] This embodiment provides a multifunctional maxillofacial surgical plasma electrosurgical unit, such as... Figures 1 to 5 As shown, in order to solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: It includes an electric knife body, a fixing base 9 and a lighting assembly. The electric knife body includes a shell 1, a cutting head 5 and a power cord 10. The cutting head 5 is provided at one end of the shell 1 and the power cord 10 is provided at the other end of the shell 1. The cutting head 5 is connected to the power cord 10. The fixing base 9 is provided at the end of the shell 1 facing the cutting head 5. The fixing base 9 is provided with a mounting groove. Both sides of the fixing base 9 are provided with slots 9-5, and the two slots 9-5 are connected to the mounting groove. The lighting assembly includes a lighting box 8 and a light component. The lighting box 8 is provided with a light component at the end facing the cutting head 5. The lighting box 8 is provided with a through hole for the cutting head 5 to pass through. Both sides of the lighting box 8 are movably provided with locking blocks 8-3. The lighting box 8 is used to fit on the cutting head 5 and is embedded in the mounting groove so that the two locking blocks 8-3 are engaged with the two slots 9-5.

[0038] Specifically, when in use, the two movable locking blocks 8-3 and the two locking slots 9-5 on the fixed base 9 allow the lighting box 8 of the lighting component to be quickly installed on the fixed base 9. The light component on the lighting box 8 faces the blade head 5, providing medical staff with illumination in the cutting direction of the electrosurgical body, improving the surgical field of vision, reducing the difficulty of the operation, and reducing the risk of accidentally injuring the patient.

[0039] This embodiment also discloses an electrosurgical body, which includes a housing 1, a cutting head 5, and a power cord 10. The cutting head 5 is installed at one end of the housing 1 and serves as an electrode base. The power cord 10 is installed at the other end of the housing 1. The cutting head 5 is connected to the power cord 10. It should be noted that the connection method between the cutting head 5 and the power cord 10 is common knowledge. For example, the cutting head 5 host is installed inside the housing 1, and the cutting head 5 is connected to the cutting head 5 host through the cutting head 5 wire. The cutting head 5 host is then connected to the power cord 10, thereby ensuring that the cutting head 5 can be powered after the power cord 10 is plugged into a power source.

[0040] For example Figure 4 As shown, this embodiment also discloses a fixing base 9. The fixing base 9 has an installation groove in the middle. Both sides of the fixing base 9 are equipped with slots 9-5. The two slots 9-5 correspond to the positions of the two slots 8-3. At the same time, the shape of the lighting box 8 is adapted to the shape of the installation groove, so that the lighting box 8 is embedded in the fixing base 9.

[0041] See Figure 1 As shown, in another embodiment of this application, recesses 8-2 are provided on both sides of the lighting box 8, and one end of a spring 8-4 is provided in each of the two recesses 8-2. The other ends of the two springs 8-4 are fixedly connected to two locking blocks 8-3.

[0042] Specifically, two recesses 8-2 are installed on the lighting box 8. The positions of the two recesses 8-2 correspond to the positions of the two slots 9-5. One end of a spring 8-4 is fixedly installed in the recess 8-2, and a locking block 8-3 is installed on the other end of the spring 8-4. When the locking block 8-3 is pressed, the locking block 8-3 compresses the spring 8-4, causing the locking block 8-3 to sink into the recess 8-2, which facilitates the installation of the lighting box 8 on the fixing seat 9. When the lighting box 8 is installed in the fixing seat 9, the positions of the locking block 8-3 and the slots 9-5 correspond, and the spring 8-4 causes the locking block 8-3 to automatically pop out and lock into the slots 9-5, thereby fixing the lighting box 8 to the fixing seat 9.

[0043] See Figure 4 As shown, in another embodiment of this application, the end of the card block 8-3 facing away from the lighting box 8 is provided with an inclined part, and the end of the card block 8-3 facing away from the outer shell 1 is provided with an abutting part, which abuts against the inner wall of the card slot 9-5.

[0044] Specifically, the shape of the locking block 8-3 is a right trapezoid, including a hypotenuse, an upper base, a lower base, and a height edge. The hypotenuse is the inclined part, the upper base is away from the lighting box 8, the lower base is close to the inside, the length of the upper base is less than the length of the lower base, and the height edge is the abutment part. In actual use, due to the special shape of the locking block 8-3, when the lighting box 8 is installed, the inclined part of the locking block 8-3 will automatically retract into the recessed part 8-2 along the inner wall of the fixing seat 9, making the assembly of this device more convenient and quick.

[0045] See Figure 3 and Figure 5 As shown, in another embodiment of this application, a first conductive sheet 12 is provided at the end of the outer shell 1 facing the blade 5. The first conductive sheet 12 is electrically connected to the power cord 10. A second conductive sheet 9-6 is provided at the end of the lighting box 8 near the outer shell 1. The second conductive sheet 9-6 is electrically connected to the lighting component and to the first conductive sheet 12.

[0046] Specifically, since the middle of the outer casing 1 is the blade 5, the first conductive sheet 12 is installed at the end of the outer casing 1. The first conductive sheet 12 is in the shape of a ring and is electrically connected to the power cord 10. The second conductive sheet 9-6 is installed at the bottom of the lighting box 8. The shape of the second conductive sheet 9-6 is adapted to the shape of the first conductive sheet 12 and is electrically connected to the lighting component. When the first conductive sheet 12 and the second conductive sheet 9-6 are in contact, power is provided to the lighting component.

[0047] See Figure 4As shown, in another embodiment of this application, the lighting component includes LED beads 8-7 and a control board 8-6. A plurality of LED beads 8-7 are disposed at one end of the lighting box 8 away from the outer shell 1. The control board 8-6 is disposed inside the lighting box 8. The plurality of LED beads 8-7 are electrically connected to the control board 8-6. The control board 8-6 is electrically connected to the second conductive sheet 9-6.

[0048] Specifically, the lighting component includes LED beads 8-7 and a control board 8-6. The control board 8-6 is configured as a ring structure with slots corresponding to the blade head 5. Several LED beads 8-7 are arranged in a ring array along the periphery of the control board 8-6. The lighting box 8 has multiple through holes corresponding to the positions of the LED beads 8-7. The control board 8-6 and LED beads 8-7 are directly embedded in the lighting box 8, and the LED beads 8-7 illuminate through the through holes. By using multiple LED beads 8-7 evenly distributed on the lighting box 8, the lighting field of the lighting component is better. The control board 8-6 is electrically connected to the second conductive sheet 9-6. When the second conductive sheet 9-6 is connected to the first conductive sheet 12, it can provide power to the second conductive sheet 9-6, and thus provide power to the LED beads 8-7.

[0049] It is understandable that the LED beads 8-7 are connected in series and then electrically connected to the control board 8-6.

[0050] See Figure 4 As shown, in another embodiment of this application, the fixing base 9 is provided with two first heat dissipation holes 9-3, and two dustproof nets 9-4 are provided on the two first heat dissipation holes 9-3. The lighting box 8 is provided with a heat dissipation component, and the position of the heat dissipation component is adapted to the position of the two first heat dissipation holes 9-3.

[0051] Specifically, two first heat dissipation holes 9-3 are installed on the mounting base 9, and the two first heat dissipation holes 9-3 are arranged opposite to each other. Two dustproof meshes 9-4 are installed on the two first heat dissipation holes 9-3. A heat dissipation component is installed on the lighting box 8. The position of the heat dissipation component is adapted to the position of the two first heat dissipation holes 9-3, so as to prevent dust from entering through the first heat dissipation holes 9-3, and at the same time, it can dissipate heat from the lighting component, prevent the light component from overheating, and extend the service life of the light component.

[0052] See Figure 4 As shown, in another embodiment of this application, the heat dissipation assembly includes an intake fan 8-5 and an exhaust fan 8-1. The intake fan 8-5 is disposed on the lighting box 8 and corresponds to the position of the first heat dissipation hole 9-3, and is electrically connected to the control board 8-6. The exhaust fan 8-1 is disposed on the lighting box 8 and is arranged opposite to the intake fan 8-5, and is electrically connected to the control board 8-6.

[0053] Specifically, in this embodiment, the intake fan 8-5 and the exhaust fan 8-1 are arranged opposite to each other. Air vents are opened on both sides of the lighting box 8, with the two vents corresponding to the positions of the first heat dissipation vent 9-3. The intake fan 8-5 and the heat dissipation fan are respectively installed on the two vents. The intake fan 8-5 is electrically connected to the control board 8-6, and then to the second conductive plate 9-6. The exhaust fan 8-1 is electrically connected to the control board 8-6, and then to the second conductive plate 9-6. Thus, the control board 8-6 controls the switching of the intake fan 8-5 and the exhaust fan 8-1, and the connection between the second conductive plate 9-6 and the first conductive plate 12 provides power to the intake fan 8-5 and the exhaust fan 8-1. It should be noted that in this scheme, the intake fan 8-5 is used to draw in air, and the exhaust fan 8-1 is used to exhaust the heat generated by the lighting components to the outside, thereby preventing heat accumulation from affecting the lifespan of the LED beads 8-7.

[0054] See Figure 4 As shown, in another embodiment of this application, flat parts 9-2 are provided on both sides of the fixing base 9, two slots 9-5 are provided on the two flat parts 9-2, and two connecting parts 9-1 are provided on the two flat parts 9-2. Both connecting parts 9-1 are detachably connected to the outer shell 1.

[0055] Specifically, the fixing base 9 has a ring-shaped structure, with flat sections 9-2 on both sides. Flat sections 9-2 are formed by cutting the sides into flat surfaces. The shape of the lighting box 8 matches the shape of the fixing base 9, allowing the lighting box 8 to be installed in a specific direction within the fixing base 9. Then, the slots 9-5 of the fixing base 9 are installed in the flat sections 9-2, facilitating observation and use. Two connecting sections 9-1 are installed on the flat sections 9-2. These connecting sections 9-1 are umbrella-shaped, matching the remaining area of ​​the outer shell 1 on the fixing base 9 after the flat sections 9-2 are cut. The connecting sections 9-1 are then detachably connected to the end of the outer shell 1, facilitating the installation of the fixing base 9 at the end of the outer shell 1. In this embodiment, the flat sections 9-2 and connecting sections 9-1 allow the lighting box 8 to be installed in a specific direction within the fixing base 9, facilitating the alignment of the slots 9-5 and the locking blocks 8-3. Simultaneously, it also facilitates the assembly of the fixing base 9 onto the end of the outer shell 1.

[0056] It should be noted that the detachable connection between the connecting part 9-1 and the outer shell 1 means that a threaded hole is provided on the connecting part 9-1, and then a bolt is used to pass through the threaded hole and fix it to the end of the outer shell 1, thereby facilitating the disassembly and assembly of the fixing seat 9.

[0057] See Figure 2 and Figure 3As shown, in another embodiment of this application, the electric knife body also includes a water outlet sleeve 6 and a water injection pipe 11. The water outlet sleeve 6 is sleeved on the knife head 5. The end of the water outlet sleeve 6 is provided with a first gap at the end of the knife head 5. The water outlet sleeve 6 is provided with a water outlet hole. The water injection pipe 11 is provided at one end of the knife head 5 on the back of the outer shell 1 and is connected to the water outlet sleeve 6.

[0058] Specifically, the water outlet sleeve 6 is fitted onto the blade head 5, but does not cover the head of the blade head 5 to avoid affecting the performance of the blade head 5. Water outlet holes are installed on the water outlet, and the number of water outlet holes can be set according to the usage scenario. In this embodiment, there are two water outlet holes, which are located in the first gap between the water outlet sleeve 6 and the blade head 5. More specifically, a water outlet tube is installed inside the outer shell 1. The water outlet tube is connected to the water outlet and then connected to the water injection pipe 11, so that the water outlet holes on the water outlet can smoothly discharge water to rinse the surgical site of the patient, making the surgical field clearer.

[0059] In the above embodiments, the addition of the water outlet sleeve 6 enables the device to have a rinsing function. However, since the blade 5 needs to conduct electricity during use, leakage may occur. Therefore, to increase the safety of the device, please refer to [further details needed]. Figure 2 and Figure 3 As shown, in another embodiment of this application, the electric knife body further includes an insulating sleeve 7, which is fitted onto the water outlet sleeve 6. A second gap is provided between the end of the insulating sleeve 7 and the end of the water outlet sleeve 6, and does not cover the water outlet hole.

[0060] Specifically, the insulating sleeve 7 is installed on the water outlet. The insulating sleeve 7 does not cover the water outlet hole. That is, a second gap is set between the end of the insulating sleeve 7 and the water outlet sleeve 6 to avoid affecting the setting of the water outlet hole. The insulation is made of rubber material, which helps to isolate the electrical energy generated by the cutter head 5 and increase the safety of the device.

[0061] Furthermore, this embodiment also includes control switches. There are three control switches: blade switch 2, fan switch 4, and LED switch 3. Blade switch 2, fan switch 4, and LED switch 3 are all electrically connected to the control board 8-6.

[0062] Specifically, the blade switch 2 is installed on the outer casing 1, the lamp switch 3 and the fan switch 4 are installed on the side wall of the lighting box 8, located at the corresponding position on the flat part of the lighting box 8, and the fixing base 9 is provided with holes corresponding to the lamp switch 3 and the fan switch 4 to avoid affecting the snap-fit ​​installation of the lighting box 8. The lamp switch 3 and the fan switch 4 are both electrically connected to the control board 8-6.

[0063] In summary, this utility model provides a multifunctional maxillofacial surgical plasma electrosurgical unit. By installing a fixing base on the outer shell, and setting a mounting slot on the fixing base for mounting the illumination box, the illumination box and the fixing base can be quickly fixed and disassembled through the engagement of the slot and the locking block. This facilitates the maintenance and replacement of the illumination box, reduces costs, and by pointing the light component on the illumination box towards the blade, it is convenient to illuminate the cutting direction of the electrosurgical unit, improve the surgical field of vision, reduce the difficulty of the operation, and reduce the risk of accidental injury to the patient.
