Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a visual bone tissue shaving system. Background Technology

[0002] Hip-preserving surgery for femoral head necrosis requires the removal of necrotic bone tissue within the femoral head to create a cavity, preparing for subsequent transplantation or implantation. Core decompression to remove necrotic bone, providing structural support, and promoting bone regeneration are the three fundamental theories for improving the long-term prognosis of hip-preserving treatment. Currently, the main methods for removing necrotic bone tissue within the femoral head are percutaneous cutting with a handpiece and X-ray observation. Surgeons repeatedly take X-ray images to observe the location of the lesion and prevent errors in the cutting action. Then, a handpiece-held percutaneous cutting head is used to remove the necrotic bone tissue, ensuring the formation of the desired cavity within the femoral head. Because the cavity created by cutting within the femoral head is relatively small, it is impossible to perform cutting under endoscopic observation simultaneously; therefore, X-ray imaging becomes the primary method of observation.

[0003] However, this resection method relies excessively on X-ray imaging for observation and localization, requiring confirmation from multiple angles. It only provides planar fluoroscopic observation, failing to pinpoint the spatial location of the lesion. Excessive use of X-rays may pose unpredictable harm to the patient. Furthermore, the inability to observe the lesion's location in real-time may result in the simultaneous removal of both healthy and necrotic bone tissue, making precise cutting of minute necrotic bone fragments impossible. This places high demands on the operator and reduces surgical efficiency. On the other hand, the burr head needs to be inserted into the lesion. Because the burr head typically integrates cleaning tubing, the entry channel is relatively large, leading to a larger wound area. Summary of the Invention

[0004] This invention provides a visual bone tissue shaving system that can simultaneously and precisely cut necrotic bone tissue while observing diseased tissue, avoiding excessive cutting of normal bone tissue, improving surgical efficiency, and also reducing the size of the grinding head and the wound area.

[0006] Optionally, the image processor is further configured to identify the connection status of the bone tissue cutting blade system and, when the bone tissue cutting blade system is identified as being connected, acquire the cutting blade system information of the connected bone tissue cutting blade system, identify the cutting blade system information, and when the identification result is abnormal, the power control module performs a safety protection operation, the safety protection operation including at least: stopping the supply of power to the grinding head.

[0008] Optionally, the cutting blade system information also includes a cutting blade system identifier. The image processor determines whether the bone tissue cutting blade system is being used for the first time based on the cutting blade system identifier. If the bone tissue cutting blade system is being used for the first time, the cutting blade system identifier and the first use time are recorded. If the current time is far from the first use time and a preset time threshold is reached, the power controller stops providing power to the grinding head.

[0009] Optionally, if the bone tissue cutting blade system is determined to be used for the first time based on the cutting blade system identifier, the power controller stops supplying power to the grinding head.

[0010] Optionally, the image processor is further configured to determine the degree of contamination of the image acquisition device based on the recognition result of the bone tissue image, and when the degree of contamination of the image acquisition device reaches a set level, to perform a cleaning operation reminder for the image acquisition device, the cleaning operation of the image acquisition device being used to control the fluid control module to start supplying the liquid and stop supplying the gas.

[0015] Compared with the prior art, the technical solution of the embodiments of the present invention has the following beneficial effects:

[0016] The image processor in the visualized bone tissue shaving device can display and process bone tissue images acquired by the image acquisition device in the bone tissue cutting blade system. This helps the operator observe diseased tissue in real time, enabling precise cutting of necrotic bone tissue and avoiding over-cutting of normal bone tissue. Furthermore, the fluid delivery device includes a liquid delivery pipeline and a common delivery pipeline. The common delivery pipeline has a first input branch, a second input branch, and a common pipeline. The common pipeline is fluidly connected to the first and second input branches and is located downstream of them. A one-way fluid delivery device is provided on the first input branch and communicates with the liquid delivery pipeline. This one-way fluid delivery device is configured to allow the liquid in the liquid delivery pipeline to flow through the first input branch to the common delivery channel, while preventing the fluid in the common delivery pipeline from entering the liquid delivery pipeline through the first input branch. By configuring a common delivery pipeline and setting a unidirectional fluid delivery device on the first input branch, while ensuring that liquid can be delivered to the grinding head and image acquisition device and gas can be delivered to the grinding head, the number of channels can be reduced, thereby reducing the size of consumables in the bone tissue cutting knife system and reducing the wound surface of the grinding head entering the channel.

[0017] Figure 1 This is a schematic diagram of the structure of a visual bone tissue shaving system according to an embodiment of the present invention;

[0018] Figure 2 This is a schematic diagram of another visual bone tissue shaving system in an embodiment of the present invention. Detailed Implementation

[0019] To make the above-mentioned objectives, features and beneficial effects of the embodiments of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0020] Reference Figure 1 This application provides a visual bone tissue shaving system 100, which includes a bone tissue cutting blade system 10 and a visual bone tissue shaving device 20.

[0021] The bone tissue cutting system 10 includes a grinding head 11, an image acquisition device 12, and a fluid delivery device 13. The grinding head 11 is used to remove bone tissue, such as necrotic bone tissue, from the femoral head. The image acquisition device 12 may include a miniature camera, etc. The miniature camera is arranged adjacent to the grinding head 11 to acquire images of the bone tissue within the femoral head and output the acquired bone tissue images.

[0022] The fluid delivery device 13 includes a liquid delivery pipeline 131 and a common delivery pipeline 132. The liquid delivery pipeline 131 is used to deliver liquid to the image acquisition device 12, and the common delivery pipeline 132 is used to output gas or liquid to the grinding head 11.

[0023] The common conduit 132 has a first input branch 1321, a second input branch 1322, and a common conduit 1324. The common conduit 1324 is fluidly connected to the first input branch 1321 and the second input branch 1322, and is located downstream of the first input branch 1321 and the second input branch 1322. The first input branch 1321 is used to receive input liquid, and a one-way fluid conveying device 1323 is provided on the first input branch 1321. The one-way fluid conveying device 1323 is configured to allow the input liquid to flow through the first input branch 1321 to the common conduit 1324, and to prevent the fluid conveyed in the common conduit 1324 from entering the first input branch 1321. The second input branch 1322 is used to convey gas.

[0024] Reference Figure 1 In some embodiments, the first input branch 1321 and the liquid delivery line 131 are relatively independent.

[0025] Reference Figure 2 In other embodiments, the first input branch 1321 is connected to the liquid delivery pipeline 131, and a portion of the liquid in the liquid delivery pipeline 131 enters the first input branch 1321. However, due to the one-way fluid delivery device 1323 provided on the first input branch 1321, gas in the common pipeline 1324 is prevented from entering the liquid delivery pipeline 131 via the first input branch 1321.

[0026] In some embodiments, the one-way fluid delivery device 1323 may be a one-way valve such as a check valve.

[0027] The visual bone tissue shaving device 20 includes an image processor 21 and a power controller 22. The image processor 21 is used to display bone tissue images acquired by the image acquisition device 12 and to perform image processing on the bone tissue images.

[0028] In some non-limiting embodiments, the bone tissue cutting blade system 10 may further include an image transmission device 14, through which bone tissue images are transmitted to a visual bone tissue shaving device 20, specifically, to an image processor 21.

[0029] In some non-limiting embodiments, the image processor 21 includes a display and recognition module 211. The display and recognition module 211 is used to display bone tissue images acquired by the image acquisition device 12 and to perform image processing on the bone tissue images.

[0030] The display and recognition module 211 may include a display screen that can display bone tissue images. The display screen can also display configuration parameters of the bone tissue cutting blade system 10, such as the rotational speed of the grinding head 11, the flow rate of the liquid, the flow rate of the gas, and other related parameters. Displaying configuration parameters on the screen facilitates parameter configuration by the operator. Furthermore, the display screen can be a touchscreen to further improve the operator's ease of use. Image processing by the display and recognition module 211 may include image capture, video recording, freezing, and playback.

[0031] The power controller 22 includes a power control module 221 and a fluid control module 222. The power control module 221 controls the power supplied to the grinding head 11, which drives the grinding head 11 to rotate. The fluid control module 222, in response to a received liquid supply command, supplies liquid to the liquid delivery line 131 and stops supplying gas to the second input branch 1322; and in response to a received gas supply command, supplies gas to the second input branch 1322 and stops supplying liquid to the liquid delivery line 131. The fluid control module 222 is connected to both the liquid supply source and the gas supply source. The liquid supply source can be water that meets surgical requirements, such as saline solution. The gas supply source can be compressed air. In some scenarios, the operating room may be equipped with both a liquid supply port and a gas supply port, and the fluid control module 222 is connected to both the liquid supply port and the gas supply port.

[0032] In some non-limiting embodiments, the fluid control module 222 may be a single module for controlling the supply of liquids and gases. In other non-limiting embodiments, the fluid control module 222 may include a gas path control module 2221 and a liquid path control module 2222. The gas path control module 2221 is configured to supply gas to the second input branch 1322 in response to a received gas supply command, and to stop supplying gas to the second input branch 1322 in response to a received liquid supply command. The liquid path control module 2222 is configured to supply liquid to the liquid delivery line 131 in response to a received liquid supply command, and to stop supplying liquid to the liquid delivery line 131 in response to a received gas supply command.

[0033] The liquid supply commands and gas supply commands can originate from the bone tissue cutting blade system 10. For example, the bone tissue cutting blade system 10 is equipped with a handheld unit connected to the grinding head 11, facilitating operator operation of the grinding head 11. A liquid / gas path control device 15 can be installed on the handheld unit. The operator can generate liquid supply commands or gas supply commands by operating the liquid / gas path control device 15. The liquid / gas path control device 15 can be a physical button, a touch button, or other type of control unit.

[0034] In some embodiments, gas and liquid can share a single liquid / gas path control device 15, and operating the liquid / gas path control device 15 can switch between liquid and gas supply conditions. For example, when the liquid / gas path control device 15 is triggered for the first time, gas is supplied by default; when the liquid / gas path control device 15 is triggered again, it switches to liquid supply. Alternatively, when the liquid / gas path control device 15 is triggered for the first time, gas is supplied by default, generating a gas supply command; when the liquid / gas path control device 15 is pressed and held, it switches to liquid supply, generating a liquid supply command. It is understood that other operating methods can also be configured to switch between gas and liquid supply conditions, which will not be listed here.

[0035] In other embodiments, separate liquid / gas control devices 15 are provided for gas and liquid respectively, i.e., gas corresponds to a gas control device and liquid control device. A gas supply command is generated when the gas control device is triggered. A liquid supply command is generated when the liquid control device is triggered.

[0036] As can be seen from the above scheme, the image processor 21 in the visual bone tissue shaving device 20 can display and recognize the bone tissue images acquired by the image acquisition device 12 in the bone tissue cutting knife system 10. This helps the operator to observe the diseased tissue in real time while simultaneously making precise cuts of necrotic bone tissue, avoiding over-cutting of normal bone tissue. In addition, the fluid delivery device 13 includes a liquid delivery pipeline 131 and a common delivery pipeline 132. By configuring the common pipeline and setting a one-way fluid delivery device 1323 on the first input branch 1321, while ensuring that liquid can be delivered to the grinding head and the image acquisition device, and gas can be delivered to the grinding head, the number of channels in the fluid delivery pipeline can be reduced, thereby reducing the size of the consumables in the bone tissue cutting knife system and reducing the wound surface of the grinding head entering the channel.

[0037] In a specific implementation, the image processor 21 is also used to identify the connection status of the bone tissue cutting blade system 10, and when the connection of the bone tissue cutting blade system 10 is detected, to acquire the cutting blade system information of the connected bone tissue cutting blade system 10, and to identify the cutting blade system information. When the identification result is abnormal, the power control module 221 executes a safety protection operation, which includes at least stopping the supply of power to the grinding head 11. Thus, when the identification result is abnormal, the safety protection operation stops the supply of power to the grinding head 11 to limit the operation of the grinding head 11, ensuring the accuracy of bone tissue planing and preventing good bone tissue from being planed.

[0038] The bone tissue cutting blade system 10 includes a memory that stores cutting blade system information. The memory can be located at a suitable location within the bone tissue cutting blade system 10. For example, the memory may be located within the handle connected to the grinding head 11. It is understood that the memory may also be located at other suitable locations within the bone tissue cutting blade system 10.

[0039] In some embodiments, the image processor 21 can obtain cutting system information by communicating with the bone tissue cutting knife system 10.

[0040] In other embodiments, the image processor 21 may also be communicatively connected to the power controller 22, which is communicatively connected to the bone tissue cutting blade system 10, and the image processor 21 obtains cutting blade system information via the power controller 22.

[0041] In some embodiments, the cutting tool system information includes at least one of the following: grinding head model and production date, etc. The cutting tool system information may be pre-stored, for example, it may be stored when the grinding head leaves the factory.

[0042] The abnormal identification result includes at least one of the following: the grinding head model does not belong to the preset model; the bone tissue cutting knife system 10 is determined to be outside the validity period based on the production date.

[0043] Different grinding head models are required in different application scenarios. These models have different diameters; for example, the diameter of the grinding head can range from 3mm to 6mm. Operators can configure preset grinding head models using the image processor 21. After the image processor 21 acquires the cutting tool system information, it compares the grinding head model in the information with the preset model. If the model matches, the recognition result is normal; otherwise, it is abnormal.

[0044] In some embodiments, the grinding head 11 has an effective usage time, which can be pre-configured. After obtaining the cutting blade system information, the manufacturer can determine whether the grinding head 11 is within its valid usage period based on the production date and effective usage time in the cutting blade system information, and the production date in the bone tissue cutting blade system 10. If the grinding head 11 is within its validity period, the identification result is considered normal. If the grinding head 11 is not within its validity period, the identification result is considered abnormal. It is understood that the cutting blade system information can also be configured with an expiration date, where the expiration date restricts the use of the grinding head within that period. In this case, the validity date can be used to determine whether the grinding head is within its effective usage time.

[0045] Furthermore, the grinding head 11 is typically a disposable consumable, and its sharpness decreases with increasing usage time, meaning it becomes dull. A dull grinding head 11 results in poor grinding performance on bone tissue. To ensure the grinding effect of the grinding head 11, in some embodiments of the present invention, the cutting blade system information also includes a cutting blade system identifier. The image processor 21 determines whether the bone tissue cutting blade system 10 is being used for the first time based on the cutting blade system identifier. If it is being used for the first time, the image processor records the cutting blade system identifier and the first use time. If the current time is within a preset time threshold of the first use time, the power controller 22 stops supplying power to the grinding head 11.

[0046] If the bone tissue cutting knife system 10 is not being used for the first time based on the cutting knife system identifier, the power controller 22 stops providing power to the grinding head 11.

[0047] By recording the identification of the cutting blade system and the first use time, the usage of the grinding head 11 can be accurately controlled, preventing the grinding head 11 from being reused or its usage time from exceeding the set time threshold, thus ensuring the hygiene of the grinding head 11 and the planing effect.

[0048] In some embodiments, when the entire cutting blade system identifier is used as a disposable consumable, the cutting blade system identifier is used to uniquely identify the cutting blade system. When the grinding head in the cutting blade system identifier is used as a disposable consumable, and other components such as the image acquisition device or fluid delivery device are used as reusable structural parts, the identification information of the grinding head is used as the cutting blade system identifier.

[0049] Furthermore, when it is determined based on the cutting blade system identifier that the bone tissue cutting blade system 10 is not being used for the first time, or when the current time is far from the first use time and a preset time threshold is reached, a reminder message is output. This reminder message is used to inform the user of the reason for stopping the power supply to the grinding head 11, so that the user can intuitively understand the reason why the grinding head 11 is not working, and facilitate the user to replace it with another bone tissue cutting blade system 10 in a timely manner.

[0050] In practice, as the grinding head 11 cuts the bone tissue, some blood and cutting debris can easily contaminate the image acquisition device 12. For example, if the image acquisition device 12 is a camera, blood and cutting debris contaminating the camera can affect the quality of the images acquired by the camera.

[0051] To ensure the image acquisition effect of the image acquisition device 12, in some embodiments of the present invention, the image processor 21 is also used to determine the degree of contamination of the image acquisition device 12 based on the recognition result of the bone tissue image. When the degree of contamination of the image acquisition device 12 reaches a set level, a cleaning operation reminder is executed for the image acquisition device 12. The cleaning operation of the image acquisition device 12 is used to control the fluid control module 222 to start supplying the liquid and stop supplying the gas.

[0052] In some non-limiting embodiments, when the power controller 22 receives a confirmation command for the cleaning operation of the image acquisition device 12, the fluid control module 222 begins supplying the liquid and stops supplying the gas. Specifically, in response to the confirmation command for the cleaning operation of the image acquisition device 12, the liquid path control module 2222 begins supplying liquid to the liquid delivery pipeline. A portion of the liquid is delivered to the image acquisition device 12 via the liquid delivery pipeline to clean the image acquisition device 12; another portion of the liquid flows to the common pipeline 1324 via the first input branch 1321 to deliver liquid to the grinding head 11 to clean the grinding head 11. At the same time, in response to the confirmation command for the cleaning operation of the image acquisition device 12, the gas path control module 2221 stops supplying gas to the second input branch 1322.

[0053] In some embodiments, the image processor 21 is further configured to acquire and display the gas or liquid supply status of the fluid control module 222. Displaying the gas or liquid supply status allows users to intuitively and conveniently ascertain the gas or liquid supply situation. For example, the image processor 21 can currently display the gas or liquid supply status using icons.

[0054] For example, the supply status can be indicated by the on or off state of the icon. A lit gas icon indicates that gas is being supplied. When the gas icon is off, such as when it is grayed out, it indicates that gas supply has stopped. Similarly, a lit liquid icon indicates that liquid is being supplied. When the liquid icon is off, such as when it is grayed out, it indicates that liquid supply has stopped.

[0055] For example, different shaped icons can be used to represent the supply status of gases or liquids. For instance, an icon representing gas flow indicates that the gas is in a supply state, while an icon representing gas stillness indicates that the gas supply has stopped. Similarly, an icon representing liquid flow indicates that the liquid is in a supply state, while an icon representing liquid stillness indicates that the liquid supply has stopped.

[0056] Understandably, other display methods can also be used to show the supply status of gas and liquid. Examples will not be given here.

[0057] In some embodiments, the image processor 21 further includes a screen expansion module 212, which is externally connected to an extended display for extended display of the bone tissue image. The extended display can be placed in the operating room, allowing doctors to clearly and intuitively understand the bone tissue grinding process. The screen expansion module 212 can be a High Definition Multimedia Interface (HDMI), a DisplayPort (DP), or other types of screen expansion modules.

[0058] In some embodiments, the image processor 21 further includes a parameter configuration entry point for receiving configuration parameters for the bone tissue cutting blade system 10. For example, the image processor 21 may display multiple parameter configuration boxes, which serve as parameter configuration entry points, allowing the user to configure the parameter within each box. The configuration parameters of the bone tissue cutting blade system 10 may include the rotational speed of the grinding head 11, the gas supply flow rate, the liquid supply flow rate, the model of the grinding head 11, the execution conditions of the gas path safety protection measures, and the execution conditions of the liquid path safety protection measures. Users can input the required parameter values ​​into the parameter configuration boxes according to their actual needs, or they can pre-set parameter levels and select the corresponding level based on their needs. For example, the gas supply flow rate can be divided into first-level, second-level, and third-level, with different supply flow rates corresponding to different levels. In practice, users can select the corresponding level according to their actual needs. Similarly, the liquid supply flow rate can be divided into first-level, second-level, and third-level, with different supply flow rates corresponding to different levels.

[0059] In some embodiments, the power control module 221 is further configured to monitor the supply status of the gas or liquid, and to execute an alarm and / or stop the supply of the liquid or gas when the supply of the gas or liquid exceeds a set flow rate threshold range. The supply status of the gas or liquid monitored by the power control module 221 includes the supply flow rate of the gas or liquid. The set flow rate threshold range can be, for example, ±P% of the configured flow rate, where P is a positive number. For example, if the supply flow rate of the gas or liquid is greater than P% of the configured flow rate, or less than -P% of the configured flow rate, an alarm is executed and / or the supply of the liquid or gas is stopped. This ensures the control accuracy and reasonableness of the gas or liquid supply flow rate, avoiding excessive or insufficient gas or liquid supply.

[0060] In some non-limiting embodiments, a pump (e.g., a peristaltic pump) is typically configured to provide the flow power for the gas or liquid. A corresponding pump is provided on the second input branch and the liquid delivery line, respectively. The power control module 221 can determine the flow rate of the gas or liquid supply by detecting the pump rotation speed. Specifically, the gas path control module 2221 can determine the gas supply flow rate by detecting the pump rotation speed on the second input branch. The liquid path control module 2222 can determine the liquid supply flow rate by detecting the pump rotation speed on the liquid delivery line.

[0061] In some non-limiting embodiments, flow sensors can be respectively installed on the second input branch 1322 and the liquid delivery pipeline 131 to detect the gas flow rate delivered by the second input branch 1322 and the liquid flow rate delivered by the liquid delivery pipeline 131. When the first input branch 1321 and the liquid delivery pipeline 131 are relatively independent, a flow sensor can be installed on the first input branch 1321 to detect the liquid flow rate delivered by the first input branch 1321.

[0062] In a specific implementation, the power control module 221 is also used to monitor the rotational speed of the grinding head 11. When the rotational speed of the grinding head exceeds a set speed threshold, it performs a safety protection operation and / or outputs an abnormal speed warning. Performing the safety protection operation may include stopping the power supply to the grinding head 11 to avoid excessive rotational speed of the grinding head 11, which could cause excessive planing of the bone tissue.

[0063] In some embodiments, the bone tissue cutting blade system 10 may further include a rotation adjustment device 16, which is coupled to the grinding head 11 and used to adjust the rotation angle of the grinding head 11. For example, the rotation adjustment device 16 can rotate and stop at any angle within a 360° range, so that the grinding head 11 can switch the planing section in a confined space. When the rotation angle of the grinding head 11 is adjusted, the angle of the image acquisition device 12 can also be adjusted accordingly, facilitating the observation and precise cutting of small portions of necrotic bone tissue at different locations, thereby improving surgical efficiency.

[0064] In some embodiments, the bone tissue cutting blade system 10 may further include a telescopic locking device 17, which controls the extended and retracted states of the grinding head 11. When the grinding head 11 is in the extended state, it can rotate under power. When the grinding head 11 is in the retracted state, its rotation is limited, and power cannot drive it to rotate. The grinding head 11 being in the extended state during bone tissue resection or in the retracted state when not resection avoids the grinding head 11 potentially obstructing observation of the lesion location when not resection, facilitating precise resection of necrotic bone tissue within the femoral head, greatly improving surgical efficiency and reducing surgical difficulty.

[0065] For example, an infrared sensor is installed on the grinding head 11. The signal detected by the infrared sensor can determine whether the grinding head 11 is in a retracted state or an extended state.

[0066] In a specific implementation, the image processor 21 can also display the extended or retracted state of the grinding head 11. The color of the icon can indicate whether the grinding head 11 is extended or retracted. For example, a blue icon indicates the grinding head 11 is extended, and a gray icon indicates the grinding head 11 is retracted. Alternatively, the style of the icon can also indicate whether the grinding head 11 is extended or retracted. An icon indicating the grinding head is extended indicates the grinding head 11 is extended, and an icon indicating the grinding head is retracted indicates the grinding head 11 is retracted.

[0067] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
