Description

Technical Field

[0001] This invention relates to the field of surgical instruments, and more particularly to a surgical planing control system and a planing manipulator. Background Technology

[0002] In surgical procedures, shaving instruments are core equipment for treating diseased tissue in the surgical area and reshaping bone or cartilage. Their performance directly determines the precision, safety, and efficiency of the surgery. To meet different surgical needs, shaving instruments feature diverse functional designs, including straight blades, curved blades, toothed cutting heads, smooth trimming heads, porous suction blades, precision carving blades, and conical grinding heads, adaptable to various tissue processing and morphological shaping operations.

[0003] Currently, most surgical shaving systems widely used in clinical practice employ a non-disposable shaving handle and replaceable blades. This means the shaving body is reusable, and different surgical procedures can be performed by replacing the outer and inner blades. In these systems, the connection between the shaving body and the main unit, as well as blade detection, primarily rely on magnetic connections. Some products use sensor-based identification, but both designs only provide basic checks on whether the blade is successfully attached to the handle; they cannot identify the specific type, specifications, or compatible function of the blade. This deficiency forces surgeons to manually adjust the main unit's operating parameters after changing blades with different functions. This not only interrupts the surgical procedure and reduces efficiency but can also lead to parameter setting deviations due to human error, affecting surgical outcomes and even increasing intraoperative risks. Furthermore, because the shaving body is a reusable component, it requires high-temperature, high-pressure, and high-humidity sterilization after each surgery. This places stringent requirements on the sensors and the motors, circuit boards, and wiring harnesses within the handle. At the same time, many of these components are imported, resulting in high overall equipment costs.

[0004] Therefore, there is an urgent need for a surgical planing control system that can solve the problem that existing surgical planing control systems can only detect whether the blade is installed, but cannot accurately identify the specific type, specifications and compatible functions of the blade. Summary of the Invention

[0005] The first objective of this invention is to provide a surgical shaving control system that can solve the problem that existing surgical shaving control systems can only detect whether the blade is installed, but cannot accurately identify the specific type, specifications, and compatible functions of the blade. At the same time, by adopting a factory-sterile design, it avoids the reliance on pre-sterilization due to the reuse of the handle. This not only solves the pain point of timeliness in emergency surgical scenarios, but also eliminates the stringent requirements of high-temperature, high-pressure, and high-humidity sterilization on components. It also avoids the problems of surgical process interruption and efficiency reduction caused by manual adjustment of host parameters, reduces the surgical risks caused by human error, and thus saves surgical preparation time, improves hospital surgical turnover rate, and adapts to the increasing surgical needs in the context of an aging population.

[0006] Based on the above concept, the technical solution adopted by this invention is as follows:

[0007] Surgical planing control system, including:

[0008] The host controller has a wire harness jack.

[0009] A planing manipulator includes a planing component and an electrical connection identification harness. The planing component is connected to the electrical connection identification harness. The electrical connection identification harness is inserted into the harness socket to establish an electrical connection between the host controller and the planing manipulator and to identify the type of the working part of the planing component. Different functions of the planing manipulator correspond to different specifications and forms of the working part of the planing component.

[0010] A negative pressure adsorber, which is connected to the planing manipulator, adsorbs bone fragments, tissue debris and rinsing fluid generated by the planing assembly during joint surgery.

[0011] The start-stop device is electrically connected to the main controller. The start-stop device is used to control the planing assembly to switch between forward, reverse and reciprocating rotation. The main controller is used to supply power to the planing manipulator and the start-stop device. Based on the type of the working part of the planing assembly identified by the electrical connection identification harness, the main controller automatically matches the preset speed gear and direction switching frequency corresponding to the type, and synchronously adjusts the adsorption power of the negative pressure adsorber to form a linkage with the operating parameters of the planing assembly.

[0012] As an optional feature of this surgical planing control system, the electrical connection identification harness includes:

[0013] The action group includes multiple action harnesses, which are connected to the drive module of the host controller to drive the planing component to complete preset actions such as forward rotation, reverse rotation, or reciprocating rotation.

[0014] A type identification harness is connected to the planing assembly and is used to transmit the type and specification parameters of the active part of the planing assembly to the host controller, and enables the host controller to match and output corresponding preset drive parameters.

[0015] An outer protective insulation layer covers the actuation group and the identification harness of this type, and is used to isolate external interference and protect the internal harness from wear.

[0016] As an optional feature of the surgical planing control system, the host controller also includes an identification unit, which comprises:

[0017] The motion recognition group includes multiple motion pins that can be matched and connected to the motion harness.

[0018] The type identification group includes multiple type identification pins that can be connected to the type identification harness in the electrical connection identification harness to identify the type and specification parameters of the active part of the planing assembly.

[0019] As an optional solution for the surgical planing control system, the start / stop device is a foot switch, which controls the start, speed adjustment and emergency stop of the negative pressure suction device by stepping on it.

[0020] The second objective of this invention is to provide a planing manipulator that can solve the problem of cross-infection caused by repeated use of instruments, disassembly and replacement of planing components, and incomplete cleaning and disinfection.

[0021] Based on the above concept, the technical solution adopted by this invention is as follows:

[0022] A planing manipulator, used in a surgical planing control system, further includes:

[0023] The housing, to which the planing assembly is connected;

[0024] A drive unit is disposed inside the housing. The output end of the drive unit is connected to the planing assembly. The drive unit is used to drive the planing assembly to work. An electrical connection identification harness is connected to the drive unit. The electrical connection identification harness can pass through the housing and be plugged into the host controller.

[0025] A negative pressure adsorption component, one end of which is connected to the planing component and the other end of which is connected to the negative pressure adsorber;

[0026] The planing assembly, the housing, the drive unit, the electrical connection identification harness, and the negative pressure adsorption assembly together constitute a single-use unit that is discarded after use.

[0027] As an alternative to this planing manipulator, the planing manipulator also includes:

[0028] An operation button is mounted on the housing.

[0029] A pressure-sensitive sensor is disposed inside the housing and can abut against the operation button. The pressure-sensitive sensor is connected to the electrical connection identification harness and is used to detect the pressing signal of the operation button and transmit it to the host controller to control the start and stop and speed adjustment of the drive unit.

[0030] As an alternative to the planing manipulator, the planing assembly includes:

[0031] An inner cutter head, which is connected to the output end of the drive unit;

[0032] An outer blade head is fitted around the inner blade head with a gap, and a negative pressure cavity is formed on the outer blade head that communicates with the negative pressure adsorption assembly.

[0033] An isolation element is sleeved on the outer periphery of the inner cutter head and rotatably connected to the inner cutter head. The isolation element is disposed inside the outer cutter head and fixedly installed on the inner wall of the outer cutter head. The inner cutter head, the outer cutter head, and the isolation element form a slag guiding cavity that communicates with the negative pressure cavity.

[0034] As an alternative to this planing manipulator, the internal cutting head includes:

[0035] The operating head performs precise planing, grinding, and finishing operations on the joint components;

[0036] The inner cutter tube has one end connected to the operating head. The inner cutter tube is a hollow cavity used to transfer the operating residue adsorbed by the operating head after operation. The inner cutter tube is inserted into the outer cutter head with a gap.

[0037] The inner blade housing has the opposite end of the inner blade tube mounted on it, and the inner blade housing is inserted into the outer blade head with a gap.

[0038] As an alternative to this planing manipulator, the negative pressure adsorption component includes:

[0039] An adsorption tube, which is connected to the negative pressure chamber;

[0040] The adapter nozzle is connected to the adsorption tube at one end and is detachably inserted into the external negative pressure adsorber. The adapter nozzle is a conical structure with conical stepped texture on the outside.

[0041] A flow controller, installed outside the adsorption tube, is used to control the start and stop of adsorption and to regulate the adsorption flow rate.

[0042] As an alternative to the planing manipulator, the planing manipulator also includes an anti-detachment component, which is disposed inside the housing and screwed to the housing. The anti-detachment component is located at the end of the drive member opposite to the planing assembly to prevent the drive member from detaching from the housing.

[0043] The beneficial effects of this invention are as follows:

[0044] This invention proposes a surgical planing control system. The planing manipulator is pre-packaged in a sterile bag and includes a planing component and an electrical connection identification harness. The planing component is connected to the electrical connection identification harness, which is inserted into a harness socket to establish an electrical connection between the main controller and the planing manipulator, accurately identifying the type of the working part of the planing component. Different functional planing manipulators correspond to different specifications and shapes of the working parts of the planing component. A negative pressure adsorber is connected to the planing manipulator, and a start / stop device is electrically connected to the main controller. The negative pressure adsorber is used to adsorb the planing material. The planing assembly maintains a clear surgical field while removing bone fragments, tissue debris, and irrigation fluid generated during joint surgery, and prevents debris from remaining inside the joint cavity. A start-stop device controls the planing assembly to switch between forward, reverse, and reciprocating rotation. The main controller powers the planing manipulator and the start-stop device. Based on electrical connections, the main controller identifies the type of the planing assembly's operating part using the wiring harness, automatically matching the corresponding preset speed setting and rotation frequency. It also synchronously adjusts the suction power of the negative pressure suction unit in conjunction with the planing assembly's operating parameters, achieving a linkage without manual intervention. The main controller automatically matches the preset speed range, direction switching frequency, and other working parameters of the corresponding blade head. The electrical connection identification harness can accurately identify the type of the working part of the planing component, allowing the main controller to quickly adapt to the corresponding surgical conditions and output the corresponding parameters. This improves the adaptability and efficiency of surgical operations and avoids the problems of existing systems that can only identify whether the planing component is installed but cannot determine the type. This requires manual control of working parameters after changing different types of planing components, which leads to interruption of the surgical process, parameter setting errors, and increased surgical risks. Moreover, the planing manipulator is designed for single-use and sterile operation. It does not require disassembly and replacement of the planing component, which fundamentally reduces the risk of cross-infection caused by repeated use of instruments, disassembly and assembly, and incomplete cleaning and disinfection. This ensures the safety of patients during surgery and eliminates the cumbersome steps of disassembling and replacing the inner and outer blade heads in the existing system. This saves surgical preparation time, improves surgical turnover rate, and avoids the safety hazards of the planing component easily loosening and falling off under magnetic connection, which threatens the smooth operation of the surgery. It also does not require adaptation to high temperature, high pressure, and high humidity sterilization environments, which greatly reduces the overall cost of the equipment and adapts to the increasing surgical needs in the context of an aging population and the clinical treatment requirements of emergency surgery.

[0045] This invention also proposes a planing manipulator, which quickly connects to the main controller via an electrical connection identification harness and accurately identifies the type of working part of the planing component. This allows the main controller to automatically adapt to the corresponding surgical parameters, and then enables the drive component to stably drive the planing component. Moreover, the entire manipulator can be directly discarded after use without disassembling or replacing any parts, eliminating the risk of cross-infection caused by the reuse and disassembly of instruments, ensuring patient surgical safety, and avoiding the risk of cross-infection caused by the reuse of instruments, disassembly and replacement of planing components, and incomplete cleaning and disinfection.

[0064] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0065] This embodiment provides a surgical shaving control system, such as Figure 1 and Figure 2As shown, in this embodiment, the surgical planing control system includes a main controller 20, a negative pressure suction device, and a start / stop device 30. The main controller 20 has a wiring harness socket. The planing manipulator 10 is configured to be sealed in a sterile packaging bag before use. The planing manipulator 10 includes a planing component 1 and an electrical connection identification wiring harness 2. The planing component 1 is connected to the electrical connection identification wiring harness 2. The electrical connection identification wiring harness 2 is inserted into the wiring harness socket to establish an electrical connection between the main controller 20 and the planing manipulator 10 and accurately identify the type of the working part of the planing component 1. Planing manipulators 10 with different functions correspond to the working parts of planing components 1 with different specifications and shapes. The negative pressure suction device... The device is connected to the planing manipulator 10, and the start / stop device 30 is electrically connected to the main controller 20. The negative pressure suction device is used to absorb bone fragments, tissue debris, and irrigation fluid generated by the planing assembly 1 during joint surgery, maintaining a clear surgical field and preventing debris from remaining inside the joint cavity. The start / stop device 30 is used to control the planing assembly 1 to switch between forward, reverse, and reciprocating rotation. The main controller 20 is used to power the planing manipulator 10 and the start / stop device 30. Based on the electrical connection identification harness 2, the main controller 20 identifies the type of the working part of the planing assembly 1, automatically matches the preset speed gear and steering switching frequency corresponding to the type, and synchronously regulates the negative pressure. The adsorption power of the adsorber is linked to the operating parameters of the planing component 1. Without manual intervention, the main controller 20 automatically matches the preset speed range, direction switching frequency, and other operating parameters of the corresponding blade head. The electrical connection identification harness 2 can accurately identify the type of the working part of the planing component 1, allowing the main controller 20 to quickly adapt to the corresponding surgical conditions and output corresponding parameters. This improves the adaptability and efficiency of the surgical operation, avoiding the problems of existing systems that can only identify whether the planing component 1 is installed but cannot determine its type, requiring manual control of operating parameters after replacing different types of planing components 1, which leads to surgical interruptions, parameter setting errors, and increased surgical risks. The planing manipulator 10 is designed for single-use sterile operation, eliminating the need to disassemble and replace the planing component 1. This fundamentally reduces the risk of cross-infection caused by repeated use of instruments, disassembly and assembly, and incomplete cleaning and disinfection, ensuring patient surgical safety. It also eliminates the cumbersome steps of disassembling and replacing the inner and outer blades 12 required by existing systems, saving surgical preparation time, improving surgical turnover, and avoiding the safety hazard of the planing component 1 easily loosening and falling off under magnetic connection, which could threaten the smooth progress of the surgery. It also eliminates the need to adapt to high-temperature, high-pressure, and high-humidity sterilization environments, significantly reducing the overall cost of the equipment and meeting the growing surgical needs and clinical treatment requirements of emergency surgery in the context of an aging population.Preferably, in this embodiment, the host controller 20 also includes a control panel, which is electrically connected to the planing manipulator 10 and the start / stop device 30, respectively. In addition to the automatic matching mode, it provides a manual adjustment interface, allowing medical staff to make personalized fine adjustments to the speed gear, steering switching frequency and adsorption power of the negative pressure adsorber of the planing component 1 according to the actual surgical conditions. At the same time, the panel integrates a status display module to provide real-time feedback on the operating parameters of the planing component 1, the identification results of the type of active part, and system fault warning information, so as to achieve dual protection of automatic control and manual intervention, and further improve the flexibility and safety of surgical operation.

[0066] Preferably, such as Figures 1-3 As shown, in this embodiment, the electrical connection identification harness 2 includes an action group 21, a type identification harness 22, and an outer insulating protective layer. The action group 21 includes multiple action harnesses 211, which are connected to the drive module of the host controller 20 to drive the planing assembly 1 to complete preset actions such as forward rotation, reverse rotation, or reciprocating rotation. The type identification harness 22 is connected to the planing assembly 1 and is used to transmit the type and specification parameters of the active part of the planing assembly 1 to the host controller 20, and enables the host controller 20 to match and output corresponding preset drive parameters. The outer protective insulating layer... 23 is encased outside the action group 21 and the type recognition harness 22 to isolate external interference, protect the internal harness from wear, and improve the adaptability and efficiency of surgical operations. Its accurate type recognition function allows the host controller 20 to adapt to different functions of the planing component 1 without manual parameter adjustment, reducing the possibility of surgical interruption and avoiding the drawback of only being able to identify whether the planing component 1 is installed but not being able to determine the specific type. This also avoids the problem of having to manually control the working parameters after changing to different types of planing components 1, which could lead to surgical interruption, parameter setting errors, and increased surgical risks.

[0067] Preferably, such as Figures 1-4As shown, in this embodiment, the host controller 20 further includes an identification unit 201. The identification unit 201 includes an action identification group 2011 and a type identification group 2012. The action identification group 2011 includes multiple action pins 20111 that can be matched and connected with the action harness 211 of the action harness 211. By matching and connecting the multiple action pins 20111 of the action identification group 2011 with the action harness 211 of the electrical connection identification harness 2, a stable drive signal transmission link is established to ensure that the host controller 20 accurately issues action commands to the planing component 1 and drives it to complete preset surgical actions such as forward rotation, reverse rotation, or reciprocating rotation. The type identification group 2012 includes multiple type identification pins 20121, which can be connected to the type identification harness 22 in the electrical connection identification harness 2 to identify the type and specification parameters of the active part of the planing component 1. This provides a reliable basis for the host controller 20 to match and output corresponding drive parameters, realizing the coordinated linkage of the identification function and the drive function. The type identification capability allows the host controller 20 to quickly adapt to planing components 1 of different specifications without manual intervention, significantly shortening the time for surgical preparation and component switching, improving surgical efficiency, avoiding deviations in the execution of planing component 1 due to a single identification method and unstable signal connection, ensuring the accuracy of surgical actions, avoiding the drawback of only being able to identify whether planing component 1 is installed but not being able to determine the specific type, and thus avoiding problems such as surgical process interruption and parameter setting errors caused by manually setting parameters after changing different types of planing components 1, reducing surgical risks.

[0068] Optionally, such as Figures 1-5 As shown, in this embodiment, four motion harnesses 211 are provided, which respectively control the forward, reverse, reciprocating, and jogging movements of the planing manipulator 10. Four motion pins 20111 are provided, each electrically connected to one of the four motion harnesses. Four type identification pins 20121 are provided, which can be adapted to connect to different types of type identification harnesses 22 to achieve accurate identification of the working type of the planing manipulator 10 and command transmission. In other embodiments, three, five, or six motion harnesses 211, three, five, or six motion pins 20111, and three, five, or six type identification pins 20121 may also be provided.

[0069] Optionally, such as Figure 1 and Figure 2As shown, in this embodiment, the start / stop device 30 is a foot switch. The foot switch controls the forward, reverse, or reciprocating rotation of the planing assembly 1 through a stepping action. The non-contact operation of the foot switch can avoid the problem of control button malfunction caused by medical staff's hands being contaminated with irrigation fluid or tissue debris. At the same time, it can also prevent the interruption of the surgical procedure caused by frequent switching of operating instruments and control buttons by the hands, solving the technical drawbacks of existing control methods that are easily affected by the surgical environment and have poor operational continuity. In other embodiments, the start / stop device 30 can also be a voice recognition control structure or an intelligent sensing control structure, etc.

[0070] For ease of understanding, such as Figure 1 and Figure 2 As shown, this embodiment also discloses a method for using a surgical planing control system. Specifically, the method for using the surgical planing control system includes the following steps:

[0071] S1: Take out a planing manipulator 10 that matches the type and specifications required for the surgery from the sterile packaging, and turn on the main controller 20;

[0072] S2: Insert the electrical connection identification harness 2 into the host controller 20. The host controller 20 identifies the type of planing manipulator 10 and displays the identification result on the host display screen.

[0073] S3: Start the planing manipulator 10, and the main controller 20 automatically matches the corresponding working parameters according to the identified type;

[0074] S4: During the process of planing and trimming joint tissue by planing manipulator 10, the negative pressure suction device is started, the suction intensity is adjusted or turned off according to the amount of tissue debris accumulation, bleeding and the clarity of the field of vision, to ensure timely removal of wound debris and small amount of blood accumulation and maintain a clear surgical field of vision.

[0075] S5: Turn off the planer operator 10. After the planer assembly 1 has completely stopped operating, turn off the power of the main controller 20, disconnect the electrical connection identification harness 2 of the planer operator 10, and then seal and package the planer operator 10 in accordance with the medical waste disposal regulations before disposing of it separately.

[0076] By using the above-described surgical planing control system, the electrical connection identification harness 2 accurately identifies the type of the working part of the planing component 1, allowing the main controller 20 to automatically match the working parameters corresponding to the surgical condition. This enables precise adaptation and operation between the planing manipulator 10 and the main controller 20, improving the adaptability and efficiency of the surgical operation. It also allows for the overall access, use, and disposal of the planing manipulator 10 without the need to disassemble and replace the planing component 1 during the operation, reducing the risk of cross-infection.

[0077] This embodiment also provides a planing manipulator 10, such as Figure 1 , Figure 5 and Figure 6 As shown, in this embodiment, the planing manipulator 10 also includes a housing 3, a drive component 4, and a negative pressure adsorption assembly 5. The planing assembly 1 is connected to the housing 3. The drive component 4 is disposed inside the housing 3, and its output end is connected to the planing assembly 1. The drive component 4 is used to drive the planing assembly 1 to work. The electrical connection identification harness 2 is connected to the drive component 4 and can pass through the housing 3 to be plugged into the host controller 20. One end of the negative pressure adsorption assembly 5 is connected to the planing assembly 1, and the other end is connected to the negative pressure adsorber. The planing assembly 1, housing 3, drive component 4, electrical connection identification harness 2, and negative pressure adsorption assembly 5 together constitute a single-use unit. After use, the entire unit is discarded. The identification harness 2 is quickly connected to the main controller 20 and accurately identifies the type of the working part of the planing component 1. The main controller 20 automatically adapts to the corresponding surgical parameters, and then the drive component 4 drives the planing component 1 stably. The negative pressure adsorption component 5 and the negative pressure adsorber work together to achieve negative pressure adsorption of bone fragments, tissue debris and irrigation fluid generated by the planing component 10 during joint surgery. The entire manipulator can be directly discarded after use without disassembling or replacing any parts, eliminating the risk of cross-infection caused by instrument reuse, disassembly and assembly, ensuring patient surgical safety, and avoiding the risk of cross-infection caused by instrument reuse, disassembly and replacement of the planing component 1 and incomplete cleaning and disinfection.

[0078] Preferably, in this embodiment, the planing manipulator 10 further includes an operation button and a pressure sensor. The operation button is mounted on the housing 3, and the pressure sensor is disposed inside the housing 3 and can abut against the operation button. The pressure sensor is connected to the electrical connection identification harness 2 and is used to detect the pressing signal of the operation button and transmit it to the host controller 20 to control the start and stop of the drive component 4 and the speed adjustment. This provides the surgical operator with a more flexible and convenient control method, eliminating the need for an additional operation panel of the host controller 20. The operator can start and stop the drive component 4 and adjust its speed while holding the manipulator, improving the continuity and convenience of the surgical operation and avoiding the need to frequently switch to the host controller. Operating the device via the panel 20 can lead to interruptions in the surgical procedure and disruption of the operating rhythm. The precise detection of the pressure-sensitive sensor ensures the stability of signal transmission, allowing the operating status of the drive component 4 to be adjusted in a timely manner according to surgical needs. This helps improve the accuracy of surgical operations and avoids situations where the speed of the drive component 4 cannot adapt to changes in the surgical site and tissue type due to the lack of local real-time control, resulting in reduced surgical efficiency or insufficient operational precision. The operation buttons and pressure-sensitive sensor are integrated into the housing 3 of the disposable manipulator, without compromising its overall unit design, without adding cumbersome disassembly and assembly steps, and without affecting the original functions of electrical connection identification and negative pressure adsorption.

[0079] Preferably, such as Figure 1 , Figure 5 and Figure 6 As shown, in this embodiment, the planing assembly 1 includes an inner cutter head 11, an outer cutter head 12, and a separator 13. The inner cutter head 11 is connected to the output end of the drive unit 4. The outer cutter head 12 is sleeved outside the inner cutter head 11 with a gap. A negative pressure cavity 121 communicating with the negative pressure adsorption assembly 5 is formed on the outer cutter head 12. The separator 13 is sleeved on the outer periphery of the inner cutter head 11 and rotatably connected to the inner cutter head 11. The separator 13 is disposed inside the outer cutter head 12 and is fixedly installed on the inner wall of the outer cutter head 12. The inner cutter head 11, the outer cutter head 12, and the separator 13 form a slag guiding cavity communicating with the negative pressure cavity 121. The inner cutter head 11 can be relatively fixed to the outer cutter head under the drive of the drive unit 4. The inner blade 11 rotates with the isolation component 13 to complete the planing operation on the target tissue, improving the stability of the rotation of the inner blade 11 and ensuring the accuracy of the planing operation. The debris guide channel, which is connected to the slag guide chamber, the negative pressure chamber 121 and the negative pressure adsorption component 5, allows the tissue debris generated during planing to be stably adsorbed and discharged through the slag guide chamber and the negative pressure chamber 121, realizing the simultaneous execution of the planing operation and debris adsorption. Moreover, this structure is integrated into the planing manipulator 10, which does not affect the accurate identification of the blade type by the electrical connection identification harness 2 and the stable control of the drive component 4. It can allow tissue debris to be discharged quickly and in a directional manner, effectively maintaining a clear surgical field and reducing the interference of residual debris on the surgical operation.

[0080] Preferably, such as Figures 1-5 As shown, in this embodiment, the inner blade head 11 includes an operating head 111, an inner blade tube 112, and an inner blade shell 113. The operating head 111 performs precise planing, grinding, and finishing operations on the joint components. One end of the inner blade tube 112 is connected to the operating head 111. The inner blade tube 112 is a hollow cavity used to transfer the operational debris adsorbed by the operating head 111 after operation. The inner blade tube 112 is inserted into the outer blade head 12 with a gap. The other end of the inner blade tube 112 is installed on the inner blade shell 113. The inner blade shell 113 is inserted into the outer blade head 12 with a gap. The hollow inner blade tube 112 design ensures smooth debris transport. With the help of the negative pressure adsorber, planing debris can be quickly cleaned up, maintaining a clear surgical field of vision. The gap assembly method of the various components of the inner blade head 11 can reduce frictional resistance during rotation, improve the response speed of the drive component 4, and the gap design can also adsorb debris a second time to form a dual debris adsorption path, ensuring a continuously clear surgical field of vision.

[0081] Optionally, in this embodiment, the operating head 111 has a circumferentially oriented cutting edge and a rounded chamfered end. The rounded chamfered end of the operating head 111 can reduce the risk of abrasion damage to normal tissues around the joint cavity, improving the safety of the surgical operation. The circumferential cutting edge can improve the efficiency and uniformity of tissue planing. In other embodiments, the operating head 111 can also be a toothed anti-slip cutting edge structure, a curved blade structure, a smooth trimming head structure, a porous suction-type blade structure, a precision carving cutting structure, or a conical grinding head, etc. Different operating heads 111 correspond to different exclusive type identification wire harnesses 22.

[0082] Optionally, in this embodiment, the isolation member 13 is a sealed bearing. The outer ring of the sealed bearing is connected to the inner wall of the outer cutter head 12, and the inner ring of the sealed bearing is connected to the inner cutter shell 113. This enables the inner cutter shell 113 to rotate stably relative to the outer cutter head 12. At the same time, the sealing structure of the bearing forms a reliable physical barrier between the slag guide cavity and the mounting cavity of the outer shell 3. This ensures the power transmission function of the inner cutter tube 112 rotating with the inner cutter shell 113 for planing operations, and also restricts planing debris, body fluids, and other substances in the slag guide cavity to a designated space, achieving the dual function of power transmission and spatial isolation. The rolling friction structure of the sealed bearing can significantly reduce the resistance when the inner cutter shell 113 rotates, improve the smoothness and stability of the inner cutter tube 112's rotational planing, and ensure the accuracy of the surgical operation. At the same time, its sealing performance can effectively prevent substances in the slag guide cavity from entering the interior of the outer shell 3, avoiding contamination or interference to core components such as the drive component 4, simplifying the overall structural design of the planing manipulator 10, and reducing production and assembly costs. In other embodiments, the spacer 13 may also be a rotating spacer sleeve or a graphite lubrication and sealing bushing, etc.

[0083] Preferably, such as Figure 1 , Figure 5 and Figure 6 As shown, in this embodiment, a slag guide hole 114 is provided through a portion of the inner blade shell 113 located inside the outer blade head 12. The slag guide hole 114 communicates with the inner cavity of the inner blade tube 112. The slag guide hole 114 is used to allow planing debris in the inner cavity of the inner blade tube 112 to enter the slag guide cavity and be discharged through the negative pressure adsorption component 5, so as to realize the simultaneous operation of planing and planing debris cleaning. The slag guide hole 114 can guide the planing debris from a position away from the negative pressure cavity 121 to a position close to the negative pressure cavity 121. With the help of the negative pressure difference formed by the negative pressure adsorption component 5, the planing debris in different positions in the slag guide cavity is driven to move towards the negative pressure cavity 121, eliminating the dead corners in the flow of the slag guide cavity, and allowing the planing debris distributed in different areas of the slag guide cavity to flow smoothly into the discharge channel, realizing the efficient and undifferentiated flow of slag in the slag guide cavity, and avoiding the problem of slag accumulation and poor flow in local areas of the slag guide cavity.

[0084] Preferably, in this embodiment, the planing assembly 1 further includes a sealing element. The sealing element is disposed at the mating point between the isolation element 13 and the inner cutter housing 113 and the mating point between the isolation element 13 and the outer cutter head 12. It is used to seal the slag guiding cavity and the cavity inside the outer shell 3, forming a double sealing and protective barrier. This blocks the material flow path between the slag guiding cavity and the cavity inside the outer shell 3, achieving complete sealing and isolation between the slag guiding cavity and the mounting cavity of the outer shell 3. At the same time, it does not affect the normal rotational movement of the inner cutter housing 113 relative to the isolation element 13 and the outer cutter head 12, ensuring the compatibility of the sealing function and the power transmission function. It prevents planing debris, tissue residue, and body fluids in the slag guiding cavity from seeping into the cavity inside the outer shell 3 through the mating gap between the isolation element 13 and the inner cutter housing 113 and the outer cutter head 12. It prevents these impurities from adhering to the surface of the drive component 4 or intruding into its transmission structure, thus avoiding malfunctions such as jamming of the drive component 4, unstable speed, and abnormal power output.

[0085] Preferably, such as Figure 1 , Figure 5 and Figure 6 As shown, in this embodiment, the planing assembly 1 also includes a retaining spring 14. The retaining spring 14 is disposed on the axial end face of the isolator 13 that is relatively close to the drive member 4. It can achieve precise axial positioning of the inner cutter head 11, restrict the forward and backward displacement of the inner cutter shell 113 along the axial direction of the outer cutter head 12, so that the inner cutter tube 112 always maintains the preset fitting gap and coaxiality with the outer cutter head 12, while not interfering with the normal rotational movement of the inner cutter shell 113 around the axis, ensuring the stability of the isolation state between the slag guide cavity and the internal mounting cavity of the outer shell 3, and maintaining the smoothness of the power transmission path.

[0086] Preferably, such as Figure 1 , Figure 5 and Figure 6 As shown, in this embodiment, the outer cutter head 12 is fixedly inserted into the outer shell 3, achieving a stable connection between the outer cutter head 12 and the outer shell 3. This forms a closed mounting cavity to accommodate the drive component 4, while simultaneously establishing a dedicated chip transmission channel from the planing operation area to the negative pressure adsorption component 5. This ensures the stability of the drive component 4 installation, allowing the output end of the drive component 4 to be reliably connected to the inner and outer heads and drive its rotation. It also ensures the unobstructed flow of the negative pressure adsorption path, achieving integrated operation where planing and chip adsorption are performed simultaneously. In other embodiments, the outer cutter head 12 and the outer shell 3 are integrally formed, simplifying the overall structural design and manufacturing process of the planing manipulator 10. No additional fasteners or sealing components are required, reducing the number of parts, lowering production and assembly costs, and improving the overall compactness and robustness of the structure, preventing structural loosening due to assembly gaps.

[0087] Preferably, such as Figure 1 , Figure 5 and Figure 6As shown, in this embodiment, the planing manipulator 10 also includes an anti-detachment component 6. The anti-detachment component 6 is disposed inside the housing 3 and screwed to the housing 3. The anti-detachment component 6 is disposed at the end of the drive component 4 away from the planing assembly 1 to prevent the drive component 4 from detaching from the housing 3. The anti-detachment component 6 can ensure that the drive component 4 maintains a stable connection with the inner cutter head 11 during the high-speed rotation of the drive inner cutter head 11 for planing operations, and there will be no axial displacement. The anti-detachment component 6 can enhance the assembly stability of the drive component 4 in the housing 3, avoid vibration, abnormal noise and other problems caused by the displacement of the drive component 4 during power transmission, and also prevent the drive component 4 from detaching from the housing 3 when it is running at high speed or subjected to slight impact from external force, thus preventing sudden failures such as the inner cutter head 11 stopping and the planing operation being interrupted due to the detachment of the drive component 4.

[0088] Preferably, such as Figure 1 , Figure 5 and Figure 6 As shown, in this embodiment, the negative pressure adsorption assembly 5 includes an adsorption tube 51, an adapter nozzle 52, and a flow controller 53. The adsorption tube 51 is connected to the negative pressure chamber 121. One end of the adapter nozzle 52 is connected to the adsorption tube 51 and is detachably inserted into the external negative pressure adsorber. The adapter nozzle 52 is a conical structure with external threaded texture. The flow controller 53 is installed outside the adsorption tube 51 and is used to control the start and stop of adsorption and adjust the adsorption flow rate. The adsorption tube 51 is connected to the negative pressure chamber 121 of the external cutter head 12, and the planing debris generated during the planing process is sucked in in time. With the help of the conical and threaded adapter nozzle 52, it can be quickly and stably detached from the external negative pressure adsorber. The connection ensures the airtightness of the negative pressure passage. The flow controller 53 installed outside the adsorption tube 51 can flexibly adjust the start and stop status of adsorption and the magnitude of negative pressure flow to adapt to the adsorption needs of planing debris in different surgical scenarios. It works in conjunction with the overall unit of the planing manipulator 10 to complete the integrated surgical operation from planing to planing debris removal. The tapered threaded adapter 52 can quickly connect and disconnect with the external negative pressure device without complicated operation, reducing the usage threshold for medical staff. The flow controller 53 can adjust the adsorption flow as needed, which can not only ensure efficient adsorption of planing debris, but also avoid damage to surrounding normal tissue due to excessive negative pressure, thereby improving the accuracy and safety of the operation.

[0089] Preferably, in this embodiment, the planing manipulator 10 further includes a shock-absorbing shell, which is sleeved outside the drive member 4 and disposed inside the outer shell 3 and abuts against the inner wall of the outer shell 3. This effectively buffers and absorbs the vibration generated when the drive member 4 is working, confining the vibration generated by the rotation of the drive member 4 inside the shock-absorbing shell, reducing the transmission of vibration to the outer shell 3 and the planing assembly 1, reducing the vibration noise when the planer is working, improving the comfort and operating experience of medical staff, and at the same time forming a stable enclosure and limiting position for the drive member 4, ensuring that the drive member 4 always maintains a coaxial position with the outer and inner heads in the installation cavity, and ensuring the accuracy of power transmission at the output end of the drive member 4.

[0090] Preferably, in this embodiment, the planing manipulator 10 further includes a damping plate, which is attached to the drive component 4 and abuts against the inner wall of the housing 3. This effectively buffers and absorbs the vibration generated when the drive component 4 is working, reduces the transmission path of the rotational driving force of the drive component 4 to the housing 3, thereby reducing the vibration amplitude of the entire disposable unit. At the same time, it can limit the displacement of the drive component 4 during operation, so that the drive component 4 always maintains a stable working posture to drive the rotation of the inner and outer heads, reducing the shaking amplitude of the hands of medical personnel due to equipment vibration, and ensuring the accuracy of the planing operation.

[0091] Preferably, such as Figure 1 , Figure 5 and Figure 6 As shown, in this embodiment, the driving component 4 includes a motor 41, a motor anti-rotation shaft 42, and a transmission shaft 43. The motor 41 is installed inside the housing 3. The motor anti-rotation shaft 42 is sleeved on the output end of the motor 41, and the motor anti-rotation shaft 42 is directly or indirectly fixedly connected to the housing 3 to prevent excessive resistance from causing the motor 41 to rotate and disengage. The transmission shaft 43 is connected to the output end of the motor 41. The motor anti-rotation shaft 42 is disposed between the motor 41 and the transmission shaft 43. Through the direct or indirect fixed connection between the motor anti-rotation shaft 42 and the housing 3, the resistance of the motor 41 driving the external... The reverse torque generated when the inner head rotates prevents the motor 41 from rotating out of the cavity of the outer casing 3. At the same time, the power of the motor 41 is stably transmitted to the outer and inner heads through the transmission shaft 43, ensuring that the outer and inner heads rotate accurately around the axis of the outer cutter head 12. This allows the outer cutter head 12 to complete a stable surgical planing operation, ensuring that the drive component 4 always maintains a good power output state in the single-use unit. This prevents the motor 41 from rotating out of the casing when the load resistance is too high, thereby avoiding problems such as power transmission failure and planing operation interruption caused by the dislocation of the motor 41.

[0092] Optionally, in this embodiment, both the outer shell 3 and the inner blade shell 113 are made of ABS plastic. ABS plastic is lightweight, wear-resistant, and impact-resistant, which can reduce the overall weight of the planer and improve the flexibility of medical personnel during surgical operations. Its good mechanical properties ensure that the components are not easily deformed or damaged during planing operations, ensuring the smoothness of the surgery. Furthermore, the material has good chemical stability and is highly safe when in contact with human tissue. ABS plastic is easy to process and mold, and its raw material cost is lower than that of materials such as metals, which can significantly reduce the production cost of the planer manipulator 10, forming a significant price advantage. This can alleviate the procurement cost pressure on medical institutions and enhance the product's market competitiveness. At the same time, its ease of mass production can meet the large-scale supply needs of disposable medical consumables, aligning with the design concept of single-use and overall disposal. In other embodiments, the outer shell 3 and the inner blade shell 113 can also be made of other engineering plastics, such as PP, PE, K-resin, PC, etc.

[0093] Optionally, in this embodiment, both the operating head 111 and the inner blade tube 112 are made of stainless steel. Stainless steel has good corrosion resistance, biocompatibility, and wear resistance, which can prevent the operating head 111 from rusting when in contact with human body fluids, reduce irritation to human tissues, and improve the safety of the surgery. Its wear resistance ensures that the inner blade tube 112 and the operating head 111 are not easily worn during high-speed rotation, maintaining a stable planing gap and ensuring consistent planing results. At the same time, the easy formability of stainless steel can meet the processing requirements of complex blade structures and is suitable for disposable design requirements, eliminating the need for additional rust prevention maintenance. In other embodiments, the operating head 111 and the inner blade tube 112 can also be made of materials such as titanium alloy or zirconia ceramic.
