Description

TECHNICAL FIELD

[0001] The embodiment of the present application relates to the technical field of medical devices, in particular to a visual bone tissue planing system. BACKGROUND

[0002] The hip-preserving surgery for femoral head necrosis needs to remove the necrotic bone tissue inside the femoral head to form a corresponding cavity, so as to prepare for the later transplantation or implantation. The core decompression to remove necrotic bone, provide structural support and promote bone regeneration are the three basic theories to improve the long-term prognosis of hip-preserving treatment. At present, the main method for removing the necrotic bone tissue in the femoral head is to use a handheld grinding head to cut and observe with an X-ray machine. The doctor observes the lesion position by repeatedly taking X-ray films to prevent cutting deviation, and then uses the grinding head clamped by the mobile phone to remove the necrotic bone tissue to ensure that the desired cavity is formed in the femoral head. Because the cavity formed by cutting inside the femoral head is small, it cannot be cut under endoscopic observation at the same time, so the X-ray film mode becomes the main observation form.

[0003] However, this removal method relies too much on X-ray machine observation and positioning, needs to be confirmed from multiple angles, and can only form a planar perspective observation, cannot confirm the spatial position of the lesion, and overuse of the X-ray machine may cause unpredictable harm to the human body. In addition, since the image of the lesion position cannot be observed in real time, normal bone tissue and necrotic bone tissue may be removed at the same time, it is difficult to accurately cut the small part of the necrotic bone tissue, the operator is required to be high, and the operation efficiency is poor. On the other hand, the grinding head also needs to be inserted into the lesion. Since the grinding head is usually integrated with some cleaning pipeline, the size of the access channel of the grinding head is large, and thus the wound surface is large. SUMMARY

[0019] In order to make the above-mentioned purposes, features and benefits of the embodiments of the present application more obvious and easy to understand, the specific embodiments of the present application will be described in detail below with reference to the drawings.

[0020] REFERENCE Figure 1 The present application provides a visual bone tissue planing system 100, which includes a bone tissue cutting knife system 10 and a visual bone tissue planing device 20.

[0021] The bone tissue cutting knife 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 part of the bone tissue in the femoral head, such as necrotic bone tissue. The image acquisition device 12 can include a miniature camera or the like. The miniature camera is arranged adjacent to the grinding head 11, used to acquire the bone tissue image of part of the femoral head, and output the acquired bone tissue image.

[0022] The fluid delivery device 13 comprises a liquid delivery line 131 for delivering liquid to the image acquisition device 12 and a common delivery line 132 for outputting gas or liquid to the grinding head 11.

[0023] The common delivery line 132 has a first input branch 1321, a second input branch 1322 and a common line 1324. The common line 1324 is in fluid communication with 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 configured to receive input liquid, and a one-way fluid delivery device 1323 is arranged on the first input branch 1321, which is configured to allow the input liquid to flow from the first input branch 1321 to the common line 1324, and to prevent the fluid delivered in the common line 1324 from entering the first input branch 1321. The second input branch 1322 is configured to deliver gas.

[0024] With reference to Figure 1 In some embodiments, the first input branch 1321 is relatively independent of the liquid delivery line 131.

[0025] With reference to Figure 2 In other embodiments, the first input branch 1321 is in communication with the liquid delivery line 131, and part of the liquid in the liquid delivery line 131 enters the first input branch 1321. However, due to the one-way fluid delivery device 1323 arranged on the first input branch 1321, the gas in the common line 1324 can be prevented from entering the liquid delivery line 131 via the first input branch 1321.

[0026] In some embodiments, the one-way fluid delivery device 1323 can be a check valve or the like.

[0027] The visualized bone tissue planing device 20 comprises an image processor 21 and a power controller 22. The image processor 21 is configured to display and process the bone tissue image acquired by the image acquisition device 12.

[0028] In some non-limiting embodiments, the bone tissue cutting knife system 10 can further comprise an image transmission device 14, through which the bone tissue image is transmitted to the visualized bone tissue planing device 20, and specifically to the image processor 21.

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

[0030] The display and recognition module 211 can include a display screen through which the bone tissue images can be displayed. The display screen can also display some configuration parameters of the bone tissue cutting knife 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 the configuration parameters through the display screen can facilitate the operator to configure the parameters. Further, the display screen can be a touch screen to further improve the operation convenience of the operator. The image processing by the display and recognition module 211 can include photographing, video recording, freezing, and playing back the images, etc.

[0031] The power controller 22 includes a power control module 221 and a fluid control module 222. The power control module 221 is configured to control the power provided to the grinding head 11, which is used to drive the grinding head 11 to rotate. The fluid control module 222 is configured to supply the liquid to the liquid delivery pipeline 131 and stop supplying the gas to the second input branch 1322 in response to receiving a liquid supply instruction, and to supply the gas to the second input branch 1322 and stop supplying the liquid to the liquid delivery pipeline 131 in response to receiving a gas supply instruction. The fluid control module 222 is connected with a liquid supply source and a gas supply source. The liquid supply source can be water, such as physiological saline, etc. that meets the requirements of the surgery. The gas supply source can be compressed air. In some scenarios, the operating room can be configured with a liquid supply port and a gas supply port, and the fluid control module 222 is connected with the liquid supply port and the gas supply port.

[0032] In some non-limiting embodiments, the fluid control module 222 can be a module configured to control the supply of the liquid and the gas. In other non-limiting embodiments, the fluid control module 222 can include a gas path control module 2221 and a liquid path control module 2222. The gas path control module 2221 is configured to supply the gas to the second input branch 1322 in response to receiving a gas supply instruction, and to stop supplying the gas to the second input branch 1322 in response to receiving a liquid supply instruction. The liquid path control module 2222 is configured to supply the liquid to the liquid delivery pipeline 131 in response to receiving a liquid supply instruction, and to stop supplying the liquid to the liquid delivery pipeline 131 in response to receiving a gas supply instruction.

[0033] The liquid supply instruction and the gas supply instruction can be from the bone tissue cutting knife system 10. For example, the bone tissue cutting knife system 10 is provided with a hand-held part connected with the grinding head 11, facilitating the operator to operate the grinding head 11. The liquid / gas path control device 15 can be arranged on the hand-held part. The operator operates the liquid / gas path control device 15 to generate the liquid supply instruction or the gas supply instruction. The liquid / gas path control device 15 can be a physical button, a touch button or other types of control parts.

[0034] In some embodiments, the gas and the liquid can share one liquid / gas path control device 15, and the operation of the liquid / gas path control device 15 can switch the supply of the liquid and the gas. For example, the liquid / gas path control device 15 is triggered for the first time, and the gas is supplied by default, and when the liquid / gas path control device 15 is triggered again, the supply of the liquid is switched. For another example, the liquid / gas path control device 15 is triggered for the first time, and the gas is supplied by default, and the gas supply instruction is generated, and when the liquid / gas path control device 15 is pressed for a long time, the supply of the liquid is switched, and the liquid supply instruction is generated. It can be understood that other operation modes can also be configured to switch the supply of the gas and the liquid, which will not be listed one by one here.

[0035] In other embodiments, the gas and the liquid correspondingly have independent liquid / gas path control devices 15, that is, the gas has a gas control device and the liquid has a liquid control device. The gas supply instruction is generated when the gas control device is triggered. The liquid supply instruction is generated when the liquid control device is detected to be triggered.

[0036] As can be seen from the above scheme, through the image processor 21 arranged in the visual bone tissue planing device 20, the bone tissue image collected by the image acquisition device 12 in the bone tissue cutting knife system 10 can be displayed and recognized, so as to help the operator to observe the necrotic bone tissue in real time and simultaneously perform accurate cutting on the necrotic bone tissue, avoiding excessive cutting of the normal bone tissue. In addition, the fluid delivery device 13 includes the liquid delivery pipeline 131 and the common delivery pipeline 132. By configuring the common pipeline and arranging the one-way fluid delivery device 1323 on the first input branch 1321, the number of channels of the fluid delivery pipeline can be reduced while ensuring that the liquid can be delivered to the grinding head and the image acquisition device and the gas can be delivered to the grinding head, thereby reducing the size of the consumables of the bone tissue cutting knife system and reducing the trauma surface of the grinding head into the channel.

[0037] In specific implementations, the image processor 21 is further configured to identify a connection state of the bone tissue cutting tool system 10, and when the bone tissue cutting tool system 10 is identified to be connected, acquire cutting tool system information of the connected bone tissue cutting tool system 10, identify the cutting tool system information, and when an identification result is abnormal, the power control module 221 performs a safety protection operation, which at least includes stopping providing power to the grinding head 11. In this way, when the identification result is abnormal, the safety protection operation is performed to stop providing power to the grinding head 11, so as to limit the working of the grinding head 11, ensure the accuracy of the bone tissue planing, and avoid good bone tissue from being planed.

[0038] The bone tissue cutting tool system 10 is provided with a memory, and the memory stores cutting tool system information. The memory can be arranged at a suitable position in the bone tissue cutting tool system 10. For example, the memory is arranged in the hand-held part connected with the grinding head 11. It can be understood that the memory can also be arranged at other suitable positions in the bone tissue cutting tool system 10.

[0039] In some embodiments, the image processor 21 can acquire the cutting tool system information by being communicatively connected with the bone tissue cutting tool system 10.

[0040] In other embodiments, the image processor 21 can also be communicatively connected with a power controller 22, the power controller 22 is communicatively connected with the bone tissue cutting tool system 10, and the image processor 21 acquires the cutting tool system information via the power controller 22.

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

[0042] The identification result being abnormal includes at least one of the following: the grinding head model does not belong to a preset model; and the bone tissue cutting tool system 10 is determined to be out of a valid date based on the production date.

[0043] In different application scenarios, different grinding head models are required. Different models of grinding heads have different diameters. For example, the diameter of the grinding head is 3mm-6mm. An operator can configure a preset model of the grinding head through the image processor 21. When the image processor 21 acquires the cutting tool system information, the grinding head model in the cutting tool system information is compared with the preset model. If the grinding head model in the cutting tool system information is consistent with the preset model, the identification result is normal. If the grinding head model in the cutting tool system information is inconsistent with the preset model, the identification result is abnormal.

[0044] In some embodiments, the grinding head 11 has an effective use duration, which can be pre-configured. When the cutting tool system information is acquired, the production date in the cutting tool system information and the effective use duration can be used to determine whether the grinding head 11 is within the effective date based on the production date in the bone tissue cutting tool system 10. When the grinding head 11 is within the effective date, it is determined that the identification result is normal. When the grinding head 11 is not within the effective date, it is determined that the identification result is abnormal. It can be understood that the cutting tool system information can also be configured with an expiration date, wherein the expiration date is a limit for the use of the grinding head within the period. At this time, the grinding head can be determined whether it is within the effective use duration based on the effective date.

[0045] Further, the grinding head 11 is usually a disposable consumable, and as the use duration of the grinding head 11 increases, the sharpness of the grinding head 11 decreases, that is, the grinding head 11 becomes blunt, and the blunt grinding head 11 has poor grinding effect on the bone tissue. In order to ensure the grinding effect of the grinding head 11, in some embodiments of the present application, the cutting tool system information further includes a cutting tool system identifier, and the image processor 21 determines whether the bone tissue cutting tool system 10 is used for the first time based on the cutting tool system identifier. If the bone tissue cutting tool system 10 is used for the first time, the cutting tool system identifier and the first use time are recorded, and if the current time is away from the first use time by a preset duration threshold, the power controller 22 stops providing power to the grinding head 11.

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

[0047] By recording the cutting tool system identifier and the first use time, the use of the grinding head 11 can be accurately controlled, the grinding head 11 can be prevented from being repeatedly used and the use duration can be prevented from exceeding the set duration threshold, and the use hygiene and the planing effect of the grinding head 11 can be ensured.

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

[0049] Further, when it is determined that the bone tissue cutting knife system 10 is not used for the first time based on the cutting knife system identification, or when the current time is away from the first use time by a preset time threshold, a reminder information is outputted, which is used to inform the reason for stopping the power supply to the grinding head 11, so that the user can intuitively know the reason for the inactivity of the grinding head 11, and the user can replace other bone tissue cutting knife systems 10 in time.

[0050] In specific implementations, as the grinding head 11 is planing the bone tissue, some blood and planing debris are easily contaminated to the image acquisition device 12. For example, the image acquisition device 12 is a camera, and the blood and planing debris contaminated to the camera will affect the image acquisition effect of the camera.

[0051] To ensure the image acquisition effect of the image acquisition device 12, in some embodiments of the present application, the image processor 21 is further used to determine the contamination degree of the image acquisition device 12 based on the recognition result of the bone tissue image, and when the contamination degree of the image acquisition device 12 reaches a set degree level, a cleaning operation of the image acquisition device 12 is performed, and 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 instruction of the cleaning operation of the image acquisition device 12, the fluid control module 222 starts to supply the liquid and stops to supply the gas. Specifically, the liquid path control module 2222 starts to supply the liquid to the liquid delivery pipeline in response to the confirmation instruction of the cleaning operation of the image acquisition device 12, and a part of the liquid is delivered to the image acquisition device 12 via the liquid delivery pipeline to clean the image acquisition device 12; another part of the liquid is delivered to the common pipeline 1324 via the first input branch 1321 to deliver the liquid to the grinding head 11 to clean the grinding head 11. At the same time, the gas path control module 2221 stops to deliver the gas to the second input branch 1322 in response to the confirmation instruction of the cleaning operation of the image acquisition device 12.

[0053] In some embodiments, the image processor 21 is further used to acquire and display the gas or liquid supply state of the fluid control module 222. By displaying the gas or liquid supply state, the user can intuitively and conveniently know the gas or liquid supply state. For example, the image processor 21 can display the gas or liquid supply state in the form of an icon.

[0054] For example, the icon is lighted or extinguished to show the supply state. The icon of the gas is lighted, which represents that the gas is in the supply state. When the icon of the gas is extinguished, such as the icon of the gas is in the gray state, it represents that the gas is in the stop supply state. The icon of the liquid is lighted, which represents that the liquid is in the supply state. When the icon of the liquid is extinguished, such as the icon of the liquid is in the gray state, it represents that the liquid is in the stop supply state.

[0055] For another example, different shapes of icons can also be used to represent the supply state of the gas or the liquid. For example, the icon of the gas flow state represents that the gas is in the supply state. The icon of the gas static state represents that the gas is in the stop supply state. For another example, the icon of the liquid flow state represents that the liquid is in the supply state. The icon of the liquid static state represents that the liquid is in the stop supply state.

[0056] It can be understood that other display modes can also be used to display the supply state of the gas and the liquid. Here, examples are not listed one by one.

[0057] In some embodiments, the image processor 21 further comprises an expansion display module 212 which circumscribes an expansion display for the expanded display of the bone tissue image. The expansion display can be placed in the operating room. The expanded display of the bone tissue image through the expansion display can facilitate the doctor to intuitively and clearly know the grinding state of the bone tissue. The expansion display module 212 can be a high-definition multimedia interface (HDMI), a display interface (DisplayPort, DP), or other types of expansion display modules.

[0058] In some embodiments, the image processor 21 further has a parameter configuration entrance for receiving the configuration parameters of the bone tissue cutting tool system 10. For example, the image processor 21 can display a plurality of parameter configuration boxes. The parameter configuration box serves as the parameter configuration entrance. The user can configure the parameter in the corresponding parameter configuration box. The configuration parameters of the bone tissue cutting tool system 10 can include the rotating speed of the grinding head 11, the supply flow of the gas, the supply flow of the liquid, the model of the grinding head 11, the execution condition of the gas path safety protection measure, the execution condition of the liquid path safety protection measure, etc. The user can input the actual demand parameter value in the parameter configuration box according to the actual demand, or can pre-set the level of the parameter, and the user selects the corresponding level according to the actual demand. For example, the supply flow of the gas can be divided into levels one, two and three, and the supply flows corresponding to different levels are different. In practice, the user can select the corresponding level according to the actual demand. Correspondingly, for example, the supply flow of the liquid can be divided into levels one, two and three, and the supply flows corresponding to different levels are different.

[0059] In some embodiments, the power control module 221 is further configured to monitor the supply status of the gas or the liquid, and perform an alarm reminder and / or stop the supply of the liquid or the gas when the supply of the gas or the liquid exceeds a set flow threshold range. The supply status of the gas or the liquid monitored by the power control module 221 includes the supply flow of the gas or the liquid. The set flow threshold range can be, for example, ±P% of the configured flow, where P is a positive number. For example, when either the supply flow of the gas or the liquid exceeds P% of the configured flow or the supply flow of the gas or the liquid is less than -P% of the configured flow, the power control module 221 performs an alarm reminder and / or stops the supply of the liquid or the gas. In this way, the control accuracy and the supply reasonableness of the supply flow of the gas or the liquid are ensured, and excessive or insufficient supply flow of the gas or the liquid is avoided.

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

[0061] In other non-limiting embodiments, a flow sensor can be provided on the second input branch 1322 and the liquid delivery pipeline 131, respectively, to detect the flow of the gas delivered by the second input branch 1322 and the flow of the liquid 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 provided on the first input branch 1321 to detect the flow of the liquid delivered by the first input branch 1321.

[0062] In specific implementations, the power control module 221 is further configured to monitor the rotation speed of the grinding head 11 and perform a safety protection operation and / or output a rotation speed abnormality reminder when the rotation speed of the grinding head exceeds a set rotation speed threshold. The safety protection operation can include stopping the supply of power to the grinding head 11 to avoid excessive rotation speed of the grinding head 11 and cause excessive planing of the bone tissue.

[0063] In some embodiments, the bone tissue cutting knife system 10 can further comprise a rotation adjustment device 16 coupled with the grinding head 11 for adjusting the rotation angle of the grinding head 11. For example, the rotation adjustment device 16 can rotate and stop at any angle within a range of 360°, so that the grinding head 11 can switch the planing position in a narrow space. When the rotation angle of the grinding head 11 is adjusted, the angle of the image acquisition device 12 can also be adjusted, which facilitates the observation and accurate cutting of the small part of necrotic bone tissue at different positions, and improves the operation efficiency.

[0064] In some embodiments, the bone tissue cutting knife system 10 can further comprise a telescopic locking device 17 for controlling the extension state and retraction state of the grinding head 11. When the grinding head 11 is in the extension state, it can rotate under the power driving. When the grinding head 11 is in the retraction state, the rotation of the grinding head 11 is limited, and the power cannot drive the grinding head 11 to rotate. The grinding head 11 is in the extension state when performing bone tissue resection or in the retraction state when not performing resection, which avoids the grinding head 11 from interfering with the observation of the lesion position when not cutting, and is beneficial to the accurate resection of the necrotic bone tissue in the femoral head, greatly improves the operation efficiency, and reduces the operation difficulty.

[0065] For example, an infrared sensor is arranged on the grinding head 11, and the signal detected by the infrared sensor can determine whether the grinding head 11 is in the retraction state or the extension state.

[0066] In specific implementation, the extension state or the retraction state of the grinding head 11 can also be displayed on the image processor 21. The display color of the icon can represent whether the grinding head 11 is in the extension state or the retraction state. For example, a blue icon indicates that the grinding head 11 is in the extension state, and a gray icon indicates that the grinding head 11 is in the retraction state.
