[0027] Reference Figures 1 to 3 According to this utility model, a dual-lamp telescopic electric scalpel includes a handle 100. A telescopic blade 110, an ultraviolet lamp group, and an illumination lamp group are installed at the front end of the handle 100. The ultraviolet lamp group and the illumination lamp group are arranged sequentially from the inside to the outside with the telescopic blade 110 as the center. The ultraviolet lamp group includes a number of ultraviolet lamp beads 120 evenly distributed around the telescopic blade 110, and the illumination lamp group includes a number of LED lamp beads 130 evenly distributed around the telescopic blade 110. A control button for controlling the operation of the telescopic blade 110 is installed at the front middle part of the handle 100, and a toggle switch 140 for switching the operation of the ultraviolet lamp group and the illumination lamp group is installed at the rear middle part of the handle 100.

[0028] It is understood that the dual-lamp telescopic electrosurgical pen provided in this embodiment of the invention, with its telescopic blade head 110 design, can adapt to surgical needs at different depths, eliminating the need for frequent tool or accessory changes, thereby simplifying the surgical procedure and improving surgical efficiency. The illumination lamp group provides a light source, optimizing visual conditions during surgery and facilitating normal surgical operations; the ultraviolet lamp group provides ultraviolet irradiation, enabling the identification of the amount and distribution of residual cancer cells in the surgical site, thus guiding the doctor to remove residual cancer cells and tissue, improving the success rate of the surgery. Simultaneously, the toggle switch 140 allows the doctor to switch between the ultraviolet lamp group and the illumination lamp group, enabling them to select different working modes of the electrosurgical pen according to different surgical scenarios, improving operational convenience and efficiency during the surgical process.

[0029] It should be noted that research has shown that specific wavelengths of ultraviolet light can be used to identify the residual amount and distribution of cancer cells, providing doctors with an effective method to determine areas requiring further treatment. This method can significantly improve the accuracy and success rate of surgery and reduce the risk of postoperative recurrence.

[0030] Understandably, placing the ultraviolet lamps closer to the center, with the surrounding LED lights, helps optimize the light propagation path. Ultraviolet light is primarily used to identify the amount and distribution of residual cancer cells; close-range irradiation ensures a more concentrated and accurate target area. Meanwhile, the peripheral LED lighting provides uniform overall illumination, reducing shadows and ensuring clarity of the surgical field. Furthermore, separating different types of light sources effectively avoids interference. If they are too close together or mixed, it may lead to decreased light source efficiency or unnecessary reflections and scattering, affecting their individual performance. Therefore, the above design ensures optimal operation for each light source, enhancing the overall effectiveness.

[0031] Preferably, according to some embodiments of the present invention, the toggle switch 140 has three positions, which are respectively used to stop the ultraviolet lamp group and the lighting lamp group, turn on the lighting lamp group, and turn on the ultraviolet lamp group. This allows doctors to easily control the working status of the ultraviolet lamp group and the lighting lamp group with a single toggle switch 140, including turning off all lights, turning on only the lighting lamp group, or turning on only the ultraviolet lamp group. This multi-functional switching mechanism improves the ease of operation and flexibility of the device, adapting to the needs of different surgical stages.

[0035] Preferred, refer to Figure 1 and Figure 2 According to some embodiments of the present invention, the diameter of the LED bead 130 is larger than the diameter of the ultraviolet bead 120, thereby improving the lighting brightness.

[0036] Preferred, refer to Figure 1 and Figure 2 According to some embodiments of the present invention, the front of the handle 100 is symmetrically provided with outwardly extending side wings 150, and LED beads 130 are corresponding one-to-one with the side wings 150. The LED beads 130 are installed at the front end of the side wings 150, which expands the illumination range, reduces the shadow area, further enhances the clarity of the surgical field, and helps to improve the accuracy of the surgery.
