[0048] Figure 1This is a schematic diagram of the overall structure of the wireless endoscopic surgical shaving device mechanism 10 according to an embodiment of this application. Figure 2 This is a three-dimensional axonometric view of the wireless endoscopic surgical shaving device mechanism 10 according to an embodiment of this application. Figure 3 This is an exploded view of the protective shell assembly 11 in the mechanism 10 of a wireless endoscopic surgical shaving device according to an embodiment of this application. Figure 4 This is a cross-sectional structural schematic diagram of the wireless endoscopic surgical shaving device mechanism 10 according to an embodiment of this application. Figures 1 to 4 As shown, the wireless endoscopic surgical shaving device mechanism 10 of this embodiment includes:

[0049] The protective shell assembly 11 is provided with a sealing cavity 30, and an opening is provided through the cavity wall at one end of the sealing cavity 30.

[0050] The movement assembly 12 is disposed within the sealed cavity 30. The movement assembly 12 includes a motor 121 having a drive shaft 1211 that passes through the opening.

[0051] A sealing element 13 is disposed within the sealing cavity 30 and sleeved on the portion of the drive shaft 1211 adjacent to the opening to fill the gap between the drive shaft 1211 and the cavity wall.

[0052] In this embodiment, the protective housing assembly 11 refers to a housing assembly made of materials with chemical resistance, heat resistance, electrical insulation, high mechanical strength, and good processing performance, such as polypropylene (PP) or polycarbonate (PC). These materials not only provide sufficient strength and durability but also ensure that the protective housing assembly 11 maintains stable performance in various environments. The protective housing assembly 11 has an internal sealed cavity 30 for accommodating the mechanism assembly 12. An opening is provided through the cavity wall at one end of the sealed cavity 30 to allow the drive shaft 1211 of the mechanism assembly 12 to pass through. The protective housing assembly 11 protects the mechanism assembly 12 from external environmental influences, such as contamination and humidity, thereby extending the service life of the equipment and ensuring its normal operation.

[0053] Figure 5 This is a schematic diagram of the main body 111 of the wireless endoscopic surgical shaving device mechanism 10 according to an embodiment of this application. Figure 6 This is a schematic diagram of the upper cover 112 in the mechanism 10 of the wireless endoscopic surgical shaving device according to an embodiment of this application. Figure 7 This is a schematic diagram of the lower housing 113 of the wireless endoscopic surgical shaving device mechanism 10 according to an embodiment of this application. In some embodiments, such as Figures 5 to 7 As shown, the protective shell assembly 11 includes:

[0054] The main body 111 has the sealing cavity 30 formed thereon;

[0055] An upper cover 112 is provided at the top of the main body 111 and a lower shell 113 is provided at the bottom of the main body 111. The upper cover 112 and the lower shell 113 are used to close the sealing cavity 30.

[0056] In this embodiment, the main body 111 is the main part of the protective shell assembly 11, forming a sealed cavity 30 for accommodating components such as the mechanism assembly 12. The upper cover 112 is a cover located on the top of the main body 111, and the lower shell 113 is a shell located at the bottom of the main body 111. The upper cover 112 and the lower shell 113 are used to seal the upper and lower parts of the sealed cavity 30, respectively. Both can be connected to the main body 111 by screws, clips, or other fixing methods, ensuring the sealing of the sealed cavity 30 while also making the assembly and disassembly of the instrument more convenient, and facilitating maintenance and replacement of parts.

[0057] In some embodiments, the lower shell 113 is provided with a protruding post 1131, and the corresponding positions of the protruding post 1131 and the upper cover 112 are provided with connecting holes 1121. The wireless endoscopic surgical shaving device also includes a fastener, which passes through the connecting holes 1121 to connect and fasten the upper cover 112, the main body 111, and the lower shell 113 together. In this embodiment, by providing the protruding post 1131 and the corresponding connecting holes 1121, it can be ensured that the upper cover 112, the main body 111, and the lower shell 113 can be accurately positioned during assembly, avoiding displacement or misalignment. By using fasteners (such as screws or rivets) to pass through the connecting holes 1121 and connect the various components together, strong connection strength and stability can be provided, ensuring that the instrument will not loosen or separate during use.

[0058] In some embodiments, a central column is also provided at a corresponding position on the main body 111, and the central column has a fixing hole at its center for the protruding column 1131 to pass through. In this embodiment, the central column on the main body 111 not only provides additional structural support, but also further enhances the stability and reliability of the entire device through the fixing hole at its center.

[0059] In some embodiments, the lower housing 113 is provided with a partition 1132, which divides the sealed cavity 30 into a first placement cavity 31 near the opening and a second placement cavity 32 away from the opening. The first placement cavity 31 is used to accommodate the movement assembly 12, and the second placement cavity 32 is used to accommodate the battery 14. In this embodiment, the partition 1132 divides the sealed cavity 30 into two independent spaces, namely the first placement cavity 31 and the second placement cavity 32. The function of the partition 1132 is to ensure isolation between these two spaces and prevent interference between the battery 14 and other components.

[0060] In this example, the core component 12 of the wireless endoscopic surgical shaving device includes a motor 121 and other related electronic components. The function of the core component 12 is to provide power and control signals to drive the device's operation. The motor 121 is the main component of the core component 12 and is typically used to provide power. It should be noted that the motor 121 in this embodiment uses a rust-resistant alloy with a primary seal, capable of withstanding 1000 cycles of high-temperature and high-pressure sterilization. It features three-phase drive, three Hall effect feedback, and can withstand 150% overload, thus ensuring the reliability and long lifespan of the motor 121. The motor 121 has a drive shaft 1211, which passes through the opening of the sealed cavity 30 and is used to drive the end cutter of the surgical shaving device.

[0061] In some embodiments, the movement assembly 12 further includes a circuit board 122, which is disposed between the upper cover 112 and the main body 111 and electrically connected to the motor 121 to provide control signals and power supply. The circuit board 122 provides core control functions and ensures the electrical connection of the display screen, buttons 15, battery 14, and motor 121.

[0062] In some embodiments, a mounting plate is provided inside the main body 111 for mounting the circuit board 122. The mounting plate can be optionally fixed to the top of the motor 121, and the circuit board 122 can be fixed to the mounting plate by screws or other means.

[0063] In this embodiment, the seal 13 is disposed inside the sealing cavity 30 and sleeved on the portion of the drive shaft 1211 adjacent to the opening. It is a component used to fill the gap between the drive shaft 1211 and the cavity wall at one end of the sealing cavity 30, which can prevent liquid or contaminants from entering the sealing cavity 30 and ensure the sealing and safety of the wireless endoscopic surgical shaving device during use.

[0064] Figure 8 This is a schematic diagram of the structure of the seal 13 in the mechanism 10 of the wireless endoscopic surgical shaving device according to an embodiment of this application. Figure 9This is a schematic cross-sectional view of the seal 13 in the mechanism 10 of a wireless endoscopic surgical planer according to an embodiment of this application. In some embodiments, such as Figure 8 and Figure 9 As shown, the seal 13 includes:

[0065] A sealing ring is provided with a through hole in the center of the sealing ring, through which the drive shaft 1211 passes, and the sealing ring is used to fill the gap between the drive shaft 1211 and the cavity wall;

[0066] A flange is located on the side of the sealing ring away from the opening and is abutted and fixed by the motor 121 and the inner wall of the cavity.

[0067] In some embodiments, the sealing ring is made of an elastic material, such as fluororubber, which is wear-resistant, temperature-resistant, and has a long service life. Under the action of the contact pressure, the flange squeezes the sealing ring, causing it to deform and thus tightly fill the gap between the drive shaft 1211 and the cavity wall.

[0068] In some embodiments, the shape of the flange matches the shape of the cavity wall so that the flange can evenly compress the sealing ring. For example, if the cavity wall is circular, the flange will also be designed to be circular, so that when the flange contacts the cavity wall, it can evenly compress the sealing ring and ensure sealing performance.

[0069] In some embodiments, the wireless endoscopic surgical shaving device mechanism 10 further includes a button 15, which includes a button 15 body and a flange portion. The flange portion is located at the bottom of the button 15 body and is used to fix the button 15 body to the upper cover 112. A portion of the structure of the button 15 body protrudes from the surface of the upper cover 112.

[0070] In some implementations, the button 15 body is made of silicone. The choice of silicone not only provides a good tactile feel, but also has certain waterproof and sterilization resistance properties, making it suitable for use in surgical environments.

[0071] Understandably, the number and position of buttons 15 can be set according to specific needs. For example, three buttons 15 can be set to control the power on, mode selection, and mode activation, respectively. These functions are commonly used in the surgical process. Through the simple operation of buttons 15, the efficiency and accuracy of the surgery can be improved.

[0072] In summary, the protective shell assembly 11 in this embodiment is made of materials with chemical resistance, heat resistance, electrical insulation, high mechanical strength, and good processing performance. It provides sufficient strength and durability to ensure stable performance in various environments, protect the core assembly 12 from external environmental influences, extend the device's service life, and ensure its normal operation. By providing the upper cover 112 and lower shell 113, and using fasteners to connect and secure them to the main body 111 in series, the sealing performance of the sealed cavity 30 is ensured. This also makes the assembly and disassembly of the instrument more convenient, facilitating maintenance and component replacement. The partition 1132 divides the sealed cavity 30 into two independent spaces, namely the first placement cavity 31 and the second placement cavity 32, ensuring isolation between these two spaces and preventing interference between the battery 14 and other components. Furthermore, the design of the seal 13, particularly the cooperation between the sealing ring and the flange, effectively prevents liquids or contaminants from entering the sealed cavity 30, ensuring the sealing and safety of the wireless endoscopic surgical shaving instrument during use. Finally, button 15 is made of silicone and has a flange structure, which can be stably fixed on the top cover 112 and provide a good operating feel, making it easy for doctors to operate during surgery.

[0073] Figure 10 This is a schematic preview of the overall shape of a wireless endoscopic surgical shaving device 100 according to an embodiment of this application. Figure 11 This is a schematic diagram of the structure of the housing 20 in a wireless endoscopic surgical shaving device 100 according to an embodiment of this application. Figure 10 and Figure 11 As shown, this application discloses a wireless endoscopic surgical shaving tool 100, comprising:

[0074] The wireless endoscopic surgical shaving device 10 as described in any of the above embodiments, and the housing 20 for accommodating the wireless endoscopic surgical shaving device 10; wherein the housing 20 is provided with a receiving cavity 40 for accommodating the wireless endoscopic surgical shaving device 10.

[0075] The housing 20 in this embodiment is an important component of the wireless endoscopic surgical shaving device 100. Its main function is to protect the internal mechanism and provide a convenient housing structure for operation and use. The design of the housing 20 needs to take into account factors such as waterproofing, dustproofing, and antibacterial properties to ensure the sterility and safety of the instrument during surgery.

[0076] In some embodiments, the housing 20 may be made of high-strength, corrosion-resistant, and biocompatible materials, such as stainless steel, titanium alloys, or high-performance plastics. These materials not only provide sufficient strength and durability but also ensure stable performance over extended periods in surgical environments.

[0077] The housing 20 has a storage cavity 40 for accommodating the wireless endoscopic surgical shaving device mechanism 10. The shape and size of the storage cavity 40 need to match the mechanism assembly 12 to ensure that the mechanism assembly 12 can be securely installed inside the housing 20. At the same time, the design of the storage cavity 40 also needs to take into account the ease of maintenance and replacement of the mechanism assembly 12.

[0078] To improve the overall waterproof performance of the wireless endoscopic surgical shaving device, the connection between the housing 20 and the core assembly 12 can be sealed with a sealing structure to prevent moisture from seeping in from the gaps between the housing 20 and the core assembly 12.

[0079] In addition, the surface of the housing 20 can be treated with antibacterial agents, such as by using an antibacterial coating or by using materials with added antibacterial agents, to reduce the growth of bacteria on the surface of the housing 20 and further improve the sterility level of the device.

[0080] In this embodiment, the wireless endoscopic surgical shaving tool 100 has a receiving cavity 40 inside the housing 20, which is equipped with a wireless endoscopic surgical shaving tool core 10 as defined in any of the above embodiments. On the one hand, this eliminates the risk of water ingress into the motor 121 and circuit board 122, extending their service life. On the other hand, it prevents contaminated fluid from flowing into the housing of the wireless endoscopic surgical shaving tool 100 during surgery, circulating within the housing, and then flowing back to the surgical site, thus avoiding the risk of cross-infection for the patient. The increased sealing of the core structure ensures the overall sterility of the core. In addition, the core 10 and the housing 20 are mutually waterproof, reducing the risk of electric shock.
