[0026] Please refer to Figures 1-2 The specific embodiment provides a hostless planing device, which aims to simplify the operation process of surgical instruments and improve the efficiency and safety of surgery through integrated design. The structure and working principle of the device will be described in detail below.

[0027] Firstly, the hostless planing device mainly consists of four core components: handle 1, display control module 2, power plug matching cable 3 and planing cutter 4. Among them, handle 1 serves as the main support structure of the device, not only bearing the installation and connection of various components, but also providing the holding part when the user operates. Display control module 2 integrates the control logic and state display function of the device, so that the user can intuitively understand the working state of the device and make corresponding operation adjustment. Power plug matching cable 3 is responsible for providing power support for the entire device, ensuring the normal operation of the motor and other components.

[0028] As Figure 3As shown in the design of the handle 1, the present embodiment adopts a split structure, i.e., the handle 1 is composed of an upper shell 11 and a lower shell 12. This design not only facilitates the assembly and maintenance of the device, but also helps to improve the structural strength and sealing performance of the device.

This design not only facilitates the assembly and maintenance of the device, but also helps to improve the structural strength and sealing performance of the device. The front end of the upper shell 11 is a mounting end 111, and the upper end surface of the mounting end 111 is used to mount the related components of the display control module 2, including the circuit board 21, the display screen 23, and the keys 22. These components are fixed on the upper shell 11 by means of fasteners or buckles, etc., to ensure their stability and reliability during the operation. At the same time, the lower end surface of the mounting end 111 is designed as a bevel, which makes the upper shell 11 more easily coupled and mounted into the lower shell mounting cavity 14 of the lower shell 12, thereby realizing the close connection of the two. Figure 3 、 4 As shown in the design of the handle 1, the present embodiment adopts a split structure, i.e., the handle 1 is composed of an upper shell 11 and a lower shell 12. This design not only facilitates the assembly and maintenance of the device, but also helps to improve the structural strength and sealing performance of the device. The front end of the upper shell 11 is a mounting end 111, and the upper end surface of the mounting end 111 is used to mount the related components of the display control module 2, including the circuit board 21, the display screen 23, and the keys 22. These components are fixed on the upper shell 11 by means of fasteners or buckles, etc., to ensure their stability and reliability during the operation. At the same time, the lower end surface of the mounting end 111 is designed as a bevel, which makes the upper shell 11 more easily coupled and mounted into the lower shell mounting cavity 14 of the lower shell 12, thereby realizing the close connection of the two.

[0030] As shown in the design of the handle 1, the present embodiment adopts a split structure, i.e., the handle 1 is composed of an upper shell 11 and a lower shell 12. This design not only facilitates the assembly and maintenance of the device, but also helps to improve the structural strength and sealing performance of the device. The front end of the upper shell 11 is a mounting end 111, and the upper end surface of the mounting end 111 is used to mount the related components of the display control module 2, including the circuit board 21, the display screen 23, and the keys 22. These components are fixed on the upper shell 11 by means of fasteners or buckles, etc., to ensure their stability and reliability during the operation. At the same time, the lower end surface of the mounting end 111 is designed as a bevel, which makes the upper shell 11 more easily coupled and mounted into the lower shell mounting cavity 14 of the lower shell 12, thereby realizing the close connection of the two. Figure 5 、 Figure 6 As shown in the design of the handle 1, the present embodiment adopts a split structure, i.e., the handle 1 is composed of an upper shell 11 and a lower shell 12. This design not only facilitates the assembly and maintenance of the device, but also helps to improve the structural strength and sealing performance of the device. The front end of the upper shell 11 is a mounting end 111, and the upper end surface of the mounting end 111 is used to mount the related components of the display control module 2, including the circuit board 21, the display screen 23, and the keys 22. These components are fixed on the upper shell 11 by means of fasteners or buckles, etc., to ensure their stability and reliability during the operation. At the same time, the lower end surface of the mounting end 111 is designed as a bevel, which makes the upper shell 11 more easily coupled and mounted into the lower shell mounting cavity 14 of the lower shell 12, thereby realizing the close connection of the two.

[0031] To achieve stable transmission between the drive shaft 114 and the planing tool 4, this embodiment includes a limiting sleeve 123 and a transmission sleeve 124 within the front cavity of the lower housing 12. The limiting sleeve 123 is connected to the drive shaft 114 via a pin or key, ensuring that it rotates with the drive shaft 114. Simultaneously, at least two protrusions 125 are symmetrically arranged on the side end face of the limiting sleeve 123, which engage with corresponding grooves 127 within the driven connector 126 of the transmission sleeve 124. This engaging structure not only achieves stable transmission between the drive shaft 114 and the transmission sleeve 124 but also helps improve transmission efficiency and service life.

[0032] In addition, a snap-fit ​​groove 128 is provided on the transmission sleeve 124, which is movably connected to the limiting sleeve 123, thereby limiting the transmission sleeve 124 within the mounting cavity 14 of the lower housing. This limiting structure design effectively prevents the transmission sleeve 124 from relative movement or loosening during the operation, thereby ensuring the overall stability and safety of the equipment.

[0033] like Figure 7 As shown, in the design of the planer 4, this specific embodiment adopts a double-blade structure, that is, the blade 41 includes an outer blade 411 and an inner blade 412 disposed inside the outer blade 411. This double-blade structure design not only improves planing efficiency but also helps to reduce resistance during the planing process and reduce surgical trauma. One end of both the inner blade 412 and the outer blade 411 is disposed within the mounting cavity 14 of the lower housing, and one end of the inner blade 412 extends into the mounting cavity of the transmission sleeve 124. During the operation, the transmission sleeve 124 drives the inner blade 412 to rotate within the outer blade 411, thereby realizing the surgical planing operation.

[0034] To improve the planing effect, this specific embodiment features serrated openings at the other ends of both the inner cutter bar 412 and the outer cutter bar 411. This serrated opening design not only increases the planing area but also helps improve planing accuracy and efficiency. Furthermore, since the cutting heads of both the inner and outer cutter bars 412 are located at the surgical site, appropriate cutting heads can be selected and replaced or adjusted according to surgical needs during actual use.

[0035] In addition to the above structural components, the present embodiment is provided with a suction cavity 1241 and a cutter bar mounting cavity 1242 on the transmission sleeve 124. The suction cavity 1241 is in communication with the negative pressure suction pipe 15 provided at the lower end of the lower shell 12, which not only facilitates the suction of tissue into the cutter head 42 for cutting, but also allows the generated waste liquid and cut tissue to be discharged from the surgical environment. The negative pressure suction pipe 15 is in communication with a separate negative pressure generating device, and by controlling the size and duration of the negative pressure, precise suction and liquid discharge operations on the surgical site can be achieved. The cutter bar mounting cavity 1242 is used to mount and fix the cutter bar 41, ensuring its stability and reliability during the operation.

[0036] In the design of the display control module 2, the circuit board 21 of the present embodiment is provided with a control chip and other necessary electronic components. The control chip is responsible for receiving the operation signals of the keys 22 and performing corresponding control operations on the motor 13 according to the preset control logic, such as starting and stopping, forward and reverse rotation, etc. At the same time, the control chip also feeds back the working state information of the device to the display screen 23 for display, so that the user can intuitively understand the current working state of the device. The display screen 23 adopts high-brightness and high-definition display technology to ensure that the working state information of the device can be clearly displayed during the operation. The keys 22 are responsible for receiving the user's operation instructions and transmitting them to the control chip for processing.

[0037] The power plug matching cable 3, as the power supply component of the device, its selection and performance parameters need to be carefully designed according to the surgical requirements and device power. In the present embodiment, the power plug matching cable 3 uses plug and cable materials that meet medical standards to ensure safety and reliability during the operation. At the same time, the length and shape of the power plug matching cable 3 are also carefully designed to allow the user to easily connect it to the power socket in the operating room and provide stable power support for the entire device.

[0038] During the operation, the user first connects the device to the power socket in the operating room through the power plug matching cable 3 and turns on the power switch. Then, the user can understand the current working state of the device by observing the display screen 23 and make corresponding operation adjustments through the keys 22 according to the surgical requirements. For example, the user can control the start and stop, forward and reverse rotation, etc. of the motor 13 through the keys 22 to achieve precise planing operation on the surgical site. At the same time, the user can also observe the negative pressure information on the display screen 23 to understand the suction effect of the negative pressure suction pipe 15 and make corresponding adjustments as needed.

[0039] After the operation is completed, the user can disassemble the connection structure between the upper shell 11 and the lower shell 12 to clean and disinfect the key components such as the planing knife 4. This split structure and easy-to-disassemble design not only facilitates the cleaning and disinfection operation of the equipment, but also helps to improve the hygiene performance and safety of the equipment. At the same time, the user can also replace or adjust the model and specifications of the key components such as the planing knife 4 according to the needs to adapt to different types of surgical needs.

[0040] In summary, the hostless planing device provided by the present embodiment has the advantages of compact structure, easy operation, and complete functions. Through integrated design and careful material selection and manufacturing process, the device not only improves the operation efficiency and safety, but also reduces the surgical trauma and patient pain. Therefore, the device has wide application prospects and market value in the medical field.

[0041] It should be noted that although the structure and working principle of the hostless planing device have been described and explained in detail in the present embodiment, in actual application process, it may still be necessary to make corresponding adjustments and optimizations according to the specific surgical needs and equipment performance. For example, the model and specifications of the planing knife 4 can be adjusted according to the size and shape of the surgical site; the power and speed of the motor 13 can be adjusted according to the surgical needs; the length and shape of the power plug matching cable 3 can be adjusted according to the environment of the operating room and the use of the equipment, etc. These adjustments and optimization measures aim to further improve the applicability and performance of the equipment to meet the actual needs in different surgical scenarios. In addition, more intelligent and automated control technologies can be introduced to improve the operation simplicity and precision of the equipment; more advanced materials and manufacturing processes can be used to improve the durability and reliability of the equipment, etc. These improvements and innovations aim to further improve the performance and application range of the equipment to meet the changing needs of the medical field.

[0042] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
