Description

Technical Field

[0001] The present application relates to the field of medical device technology, and in particular to an auxiliary control method and device for ciliary photocoagulation surgical equipment. Background Art

[0002] In recent years, diode laser transscleral cyclophotocoagulation has been widely used in the treatment of refractory glaucoma and has achieved satisfactory results. The procedure is simple to operate and can quickly and effectively reduce intraocular pressure and relieve symptoms such as eye pain. The mechanism of action of cyclophotocoagulation surgery includes: the pigmented tissue absorbs laser energy and produces a thermal effect, which causes coagulative necrosis of the ciliary epithelium and matrix, destroys ciliary epithelial cells, and reduces aqueous humor secretion; after photocoagulation of the ciliary crown, the root of the iris is pulled backward to reduce the obstruction of the trabecular meshwork while widening the chamber angle and deepening the anterior chamber; photocoagulation of the flat part or more posterior part of the ciliary body increases the drainage of aqueous humor from the uveal sclera; and intraocular pressure is controlled through these effects. Based on relevant clinical studies, in order to achieve better postoperative results, a half-dose cyclophotocoagulation operation can be used to completely destroy part of the ciliary body and reduce (rather than completely eliminate) the production of aqueous humor. The laser dose control and adjustment of the surgical equipment during this operation is one of the important factors affecting the surgical effect.

[0003] In the process of realizing the present invention, the inventors found that in existing practice, during the implementation of photocoagulation surgery, when setting the laser power of the surgical equipment, the laser power is adjusted based on the doctor's personal experience, and whether the power is appropriate is confirmed based on whether an effective impact blasting sound is heard; under this method, due to the doctor's individual hearing reasons and environmental factors, improper power adjustment is likely to occur, affecting the actual surgical effect.

[0004] Therefore, in the implementation scenario of ciliary body photocoagulation surgery, how to ensure that the laser dose adjustment setting during the surgery is appropriate to ensure the surgical effect has become a technical problem that needs to be solved urgently.

[0006] In order to overcome the problems existing in the related art at least to a certain extent, the embodiments of the present application provide an auxiliary control method and device for ciliary photocoagulation surgical equipment, which effectively indicates whether the adjustment setting of the laser dose is appropriate based on the detection and recognition of the sound signal obtained by sound pickup sensing.

[0009] In a possible implementation, the performing a control operation corresponding to the detection and recognition result based on the detection and recognition result further includes: When the percussion blast sound matching the occurrence timing of the output laser light is not identified, a second message is generated; In response to the generation of the second message, the current value of the laser output power parameter of the device is detected and judged. If the current value is less than a preset upper limit threshold, the current value is increased by a preset adjustment value for subsequent new laser output. Otherwise, an indication message indicating that an abnormality has occurred is output.

[0010] In a possible implementation, the lower threshold is 1000 mW, and the upper threshold is 3000 mW.

DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other implementation methods obtained by ordinary technicians in the field without making creative work belong to the scope of protection of the present application.

[0024] It should be noted that the modifications of "one" and "plurality" mentioned in the present application are illustrative rather than restrictive, and those skilled in the art should understand that unless otherwise clearly indicated in the context, it should be understood as "one or more".

[0025] The names of the messages or information exchanged between multiple devices in the embodiments of the present application are only used for illustrative purposes and are not used to limit the scope of these messages or information.

[0026] As described in the background technology, in recent years, diode laser transscleral cyclophotocoagulation has been widely used in the treatment of refractory glaucoma and has achieved satisfactory results. The procedure is simple to operate and can quickly and effectively reduce intraocular pressure and relieve symptoms such as eye pain. The mechanism of action of cyclophotocoagulation surgery includes: the pigmented tissue absorbs laser energy and produces a thermal effect, causing coagulative necrosis of the ciliary epithelium and matrix, destroying ciliary epithelial cells, and reducing aqueous humor secretion; after photocoagulation of the ciliary crown, the root of the iris is pulled backward to reduce the obstruction of the trabecular meshwork while widening the chamber angle and deepening the anterior chamber; photocoagulation of the flat part or more posterior part of the ciliary body increases the drainage of aqueous humor from the uveal sclera; and the intraocular pressure is controlled through the effects of these aspects. Based on relevant clinical studies, in order to achieve better postoperative results, a half-dose cyclophotocoagulation operation can be used to completely destroy part of the ciliary body and reduce (rather than completely eliminate) the production of aqueous humor. The laser dose control and adjustment of the surgical equipment during this operation is one of the important factors affecting the surgical effect.

[0027] During the photocoagulation surgery, when setting the laser power of the surgical equipment, the existing method is to adjust the laser power based on the doctor's personal experience and confirm whether the power is appropriate based on whether an effective impact blasting sound is heard. Under this method, due to the doctor's individual hearing problems and environmental factors, improper power adjustment is likely to occur, affecting the actual surgical effect.

[0028] In view of this, the present application proposes an auxiliary control method for a ciliary photocoagulation surgical device. Figure 1 The figure is a schematic diagram illustrating the process of an auxiliary control method for a ciliary body photocoagulation surgical device in one embodiment.

[0029] like Figure 1 As shown, in this embodiment, the auxiliary control method for ciliary photocoagulation surgical equipment proposed in this application includes: Step S110, sensing the sound information of the environment in which the device is located during the photocoagulation surgery to generate audio signal data; It is easy to understand that a relevant sound sensing device can be set on the photocoagulation surgical device, based on which the sound information sensing in this step is performed, and a relevant data acquisition and processing means (such as a data acquisition card) is used to generate audio signal data; It should also be noted that, based on the scenario requirements of this application, the sound sensing device here should have high sensitivity and a wide frequency response range so as to accurately capture tiny sound changes in actual surgical scenarios. At the same time, a layout method that is conducive to the sensing of blow and explosion sounds should be adopted. For example, the sensing device can be arranged on a component that can be close to the patient's eyes during surgery, such as arranging a high-performance MEMS microphone sensor at the end of the laser emitting optical fiber of the device.

[0030] Step S120, detecting and identifying the impact and blasting sound of the photocoagulation surgery according to the audio signal data obtained in step S110, and performing a control operation corresponding to the result based on the detection and identification result; It is easy to understand that in this step, the detection and identification of audio information data can be implemented by using existing related audio signal processing algorithms. Based on the scenario requirements of this application and for the sake of ease of implementation, as a specific implementation method, in this embodiment, Figure 2 As shown, the process of detecting and identifying the percussion and blasting sounds of photocoagulation surgery based on audio signal data includes: a. Preprocessing the audio signal data. The preprocessing here may include denoising processing, enhancement processing, etc. After preprocessing, intermediate signal data is obtained; b. Extracting features from the intermediate signal data to obtain acoustic feature information of the signal, where the acoustic feature information at least includes frequency spectrum feature information and waveform feature information; c. Based on the acoustic feature information, pattern recognition technology is used to detect and identify the impact and blasting sounds; It is easy for those skilled in the art to understand that the percussion popping sound in photocoagulation surgery is a tiny explosion or blasting sound in the tissue caused by laser burning, similar to a slight "POP" sound, and has certain spectral characteristics and waveform characteristics. In the application scenario of the present application, relevant pattern recognition methods can be used to distinguish and identify the sound, such as using relevant classification algorithms, including vector machines SVM, decision trees, neural networks, etc. to detect and identify it. The specific algorithm implementation involved in this part can be found in the existing relevant technical literature, and this application will not go into details here.

[0031] In this embodiment, a control operation corresponding to the result is performed based on the detection and identification result, including: when an impact blasting sound matching the occurrence timing of the output laser is identified, a first message is generated, and in response to the generation of the first message, indication information is output to indicate that the output laser photocoagulation effect is effective.

[0032] It should be noted that the audio signal data in the present application is a timing signal data. The matching of the occurrence timing in the above description means that the device performs a laser output striking operation. For example, if the output occurs at T1, the striking blasting sound is identified in the audio signal data within a certain time period starting from T1; then the first message as above is generated, and the corresponding indication information is output.

[0033] In the present application, the indication information can be output in the form of display output, such as displaying "the strike is effective" on the display screen of the device to prompt the doctor that effective photocoagulation output has occurred.

[0034] The technical solution of the present application senses the sound information of the environment in which the equipment is located during the photocoagulation operation, and based on the detection and identification of the sensed audio data, accurately determines the generation of effective strike blasting sounds, thereby indicating that the setting of the laser dose is effective, thereby avoiding improper laser dose adjustment caused by inaccurate detection of effective strike blasting sounds in the existing method, which is beneficial to ensuring the effectiveness of the photocoagulation operation.

[0035] To facilitate understanding of the technical solution to be protected in the present application, the technical solution of the present application is introduced and explained with reference to some other embodiments below.

[0036] As described in the background art, in the semi-dose glaucoma photocoagulation surgery, the goal is to completely destroy part of the ciliary body and reduce the production of aqueous humor, rather than completely eliminate the production of aqueous humor.

[0037] According to the inventor's observation and thinking of this scenario, in practice, there are situations where the ciliary body of patients is in different states, such as different ciliary pigment conditions of different individuals, and there are differences in the performance of optical fibers used in surgery, such as the performance difference between optical fibers that have been used multiple times and optical fibers that are used for the first time. These differences and differences will make it difficult to accurately control the laser dose used for effective photocoagulation in practice. During the implementation of existing surgeries, the control of the required laser dose is usually carried out by limiting the laser action time parameters and manually adjusting the power parameters in combination with the sound of the explosion. This requires a high level of experience from the surgical operator and the operation during the operation is more complicated.

[0038] Based on the above analysis, in the actual scenario of this application, in order to solve this problem to a certain extent, in one embodiment, the auxiliary control method for ciliary photocoagulation surgical equipment in this application includes the following steps: Sense the sound information of the environment in which the device is located during the photocoagulation surgery and generate audio signal data; Detect and identify the impact and blasting sounds of the photocoagulation surgery according to the audio signal data, and perform a control operation corresponding to the result based on the detection and identification result; Among them, based on the detection and identification results, control operations corresponding to the results are performed, including: when a percussion blasting sound matching the occurrence timing of the output laser is identified, a first message is generated, and in response to the generation of the first message, indication information is output to indicate that the output laser photocoagulation effect is effective.

[0039] Furthermore, in this embodiment, executing a control operation corresponding to the result based on the detection and recognition result also includes: In response to the generation of the first message, the current value of the laser output power parameter of the device is detected and judged. If the current value is greater than a preset lower limit threshold, the current value is lowered by a preset adjustment value for subsequent new laser output, otherwise the current value is kept unchanged.

[0040] It should be noted here that in the technical scenario of the present application, as mentioned above, the laser dose required in photocoagulation surgery is not easy to control accurately, but the approximate range can be determined. For example, if the Guangtai Supra 810 ophthalmic laser device is used and the action time is set to 2s, the power range is about 1000mW to 3000mW.

[0041] Based on this, since the blasting sound of an effective strike can be accurately identified, fine adjustment of the laser dose during the surgical procedure becomes possible; the inventor further analyzed the needs of the technical scenario of the present application, weighed the pros and cons of excessive burning and ineffective strike, and in this embodiment, specifically proposed a solution to prevent the use of excessive power to achieve effective strike blasting by adopting the above-mentioned configuration method, that is, on the premise that effective strikes can be achieved, the power is automatically fine-tuned with a downward trend; this is beneficial for achieving effective strikes with as little power as possible for different actual situations, and reducing the adverse consequences of strikes with excessive power, such as burns.

[0042] In the above implementation process, the lower limit threshold and the preset adjustment value in the method configuration can be selected and set based on the instrument configuration in the actual scenario. For example, based on the above-mentioned instruments and configurations, in some implementation scenarios, the lower limit threshold can be set to 1000mW, and the preset adjustment value can be set to 100mW based on experience.

[0043] Correspondingly, in this embodiment, executing a control operation corresponding to the result based on the detection and recognition result also includes: When the percussion blast sound matching the occurrence timing of the output laser light is not identified, a second message is generated; In response to the generation of the second message, the current value of the laser output power parameter of the device is detected and judged. If the current value is less than a preset upper limit threshold, the current value is increased by a preset adjustment value for subsequent new laser output. Otherwise, an indication message is output to indicate that an abnormality has occurred.

[0044] In this way, by combining the two control methods of increasing and decreasing the power, an automatic power adjustment mechanism based on the machine equipment is realized, and the appropriate power configuration for achieving effective photocoagulation is searched based on this mechanism, which can reduce the manual labor of the user; in the process of implementing the control of increasing the power, continuing with the previous example, the upper limit threshold can be set to 3000mW.

[0045] It should also be noted that in this process, the way of handling the situation where the current value exceeds the upper limit threshold is a setting of a safety mechanism; in general, the high-adjustment configuration, that is, when the laser output fails to hit the effective photocoagulation point, the power setting is automatically increased with a preset step within the upper limit range. If effective photocoagulation still cannot be achieved when the upper limit is reached or even exceeded, it generally indicates that an abnormal situation has occurred, such as equipment failure. At this time, relevant indication information is output so that relevant personnel can respond, such as performing equipment maintenance and calibration, and confirming whether the patient's condition is specific.

[0046] In addition, it should be noted that, in the actual application process of the device control method using the above configuration, the initial value of the laser output power parameter can be flexibly set within the power range, such as being set to be the same as the lower limit threshold.

[0047] In this embodiment, through the above-mentioned automatic control method, when the blasting sound energy is effectively struck and accurately identified, photocoagulation point generation can be achieved with a more appropriate laser output dose, and the manual adjustment operation of the device user is reduced. That is, in actual surgical applications, the device improves the surgical efficiency to a certain extent based on the reduction of manual operation links by the operator while achieving better surgical results.

[0048] Regarding surgical efficiency, in the technical scenario of this application, generally speaking, highly qualified doctors, based on their rich experience, can quickly set the power parameters of the equipment to a relatively appropriate situation, that is, relatively achieve higher surgical efficiency; a careful analysis of the key points here clearly involves the selection and determination of both the initial value and the adjustment value of the power parameters.

[0049] Based on this, it is obvious that the technical implementation method newly proposed in the above embodiments of the present application is a solution for automatic power adjustment based on the recognition of effective blow blasting sound from the perspective of refinement and reduction of cumbersome operations; However, when applying this control method, in actual scenarios, if the initial value and step adjustment value of the power parameter are not set properly, it will lead to lower overall efficiency compared to manual adjustment operations; especially considering the scarcity of highly qualified doctors, relevant technical means should be used to avoid the potential defects brought about by this new implementation method.

[0050] Further from the technical scenario of the present application, if the step adjustment value is adjusted dynamically, it will be somewhat blind, which is contrary to the technical idea of ​​fine-grained regulation and risk control in the above-mentioned embodiment; therefore, in the present application, starting from the initial value setting of the power parameter, the defects brought about by this automatic power adjustment method can be avoided to a certain extent.

[0051] Specifically, based on the above embodiments, in one implementation, the auxiliary control method proposed in the present application further includes: The power parameter setting value each time the first message is generated is recorded to form record data; based on the record data, a parsing analysis is performed to determine the recommended value of the initial value of the power parameter; the recommended value is output, such as a display output, for reference by the device user when setting the initial value of the power parameter.

[0052] In actual implementation, in the above process, relevant statistical analysis algorithms, such as calculating the average value, can be used to perform analytical analysis and calculation to obtain the recommended value; the recorded data can be stored in a data structure similar to a FIFO queue. The data in such recorded data reflects the device status and the device status in the current time period, and the recommended value derived from this is more referenceable.

[0053] In the technical scenario of this application, the number of effective photocoagulation points is also a factor that affects the expected effect of the surgery. For example, the proposal of the half-volume ciliary body photocoagulation surgery procedure is essentially the reduction of photocoagulation points in a certain dimension. Based on this, in another embodiment, the auxiliary control method for ciliary photocoagulation surgical equipment of the present application includes the following steps: Sense the sound information of the environment in which the device is located during the photocoagulation surgery and generate audio signal data; Detect and identify the impact and blasting sounds of the photocoagulation surgery according to the audio signal data, and perform a control operation corresponding to the result based on the detection and identification result; Among them, based on the detection and identification results, control operations corresponding to the results are performed, including: when a percussion blasting sound matching the occurrence timing of the output laser is identified, a first message is generated, and in response to the generation of the first message, indication information is output to indicate that the output laser photocoagulation effect is effective.

[0054] Furthermore, in this embodiment, the auxiliary control method of the present application further includes: The number of times the first message is generated is statistically processed, and indication information for indicating the number of valid photocoagulation points is output.

[0055] Specifically, in actual implementation, a counting variable can be set. After initialization, each time the first message is generated, the counting variable is incremented by one, and relevant indication information is output according to the value of the counting variable, so that the surgeon can control the progress of the operation in a timely and accurate manner.

[0056] On this basis, further, the auxiliary control method of the present application also includes, when the statistical generation number of the first message exceeds a preset number threshold, outputting indication information for prompting that the photocoagulation dot target is completed.

[0057] For example, in a half-dose photocoagulation surgery, 8 to 20 photocoagulation points are generally required. The preset number threshold here can be selected and set within this range based on demand. For example, for patient A, the target number of photocoagulation points set for the treatment is 14. When the count of the first message reaches this value, an indication message indicating that the output target has been achieved is displayed.

[0058] In the above-mentioned embodiments, the output of various indication messages of the device is usually displayed and outputted through the display interaction components of the existing device, that is, the indication information is outputted in the form of display output; for example, the indication message of the corresponding state during the execution of the control method is outputted through the touch display screen of the device.

[0059] This display output method is too simple, and in some cases, the user may fail to see the relevant instruction message due to negligence, which may lead to adverse consequences. Based on this, in order to avoid such a situation, in some embodiments, the instruction information is output in the form of display output and / or sound output;

[0060] In the above-mentioned output implementation, when it comes to outputting instruction messages in the form of sound output, since the core point of the technical solution of the present application is to identify the sound of impact and blasting based on the collected sound data, the sound of outputting the instruction message in this case will cause additional interference to the identification, and relevant technical means need to be adopted to deal with this.

[0061] Therefore, in some embodiments, the sound indication output is carried out in a directional propagation manner to reduce the generation of related interference, such as providing an earphone component electrically connected to the controller, and the user listens to the related sound output through the earphone component to obtain the indication information.

[0062] In some embodiments, during the sound indication output process, the voice data is machine synthesized, and the waveform data corresponding to the voice signal generated during the synthesis process is known. Technically, relevant digital signal processing technology can be used to process the sensed audio signal data according to the waveform data to eliminate related interference, such as frequency domain filtering, adaptive filtering, etc. to achieve this purpose; In order to balance the cost and effect of technical implementation, in one embodiment, an adaptive filtering method is used to achieve this purpose. Specifically, in the following example Figure 2 In step a shown in the figure, the process of preprocessing the audio signal data includes: using the speech signal generated during the sound indication output process as a reference signal; Adopting an adaptive algorithm to adjust the coefficients of the adaptive filter so that the filter output is close to the reference signal; The output of the adaptive filter is subtracted from the signal corresponding to the audio signal data by a subtractor.

[0063] In the above process, the adaptive algorithms include the minimum mean square error algorithm, the recursive least squares algorithm, the normalized minimum mean square error algorithm, etc. Further technical details about the implementation of adaptive filtering can be found in the records of existing public technical materials, and this application will not go into further details here.

[0064] In one embodiment, the present application also provides a ciliary body photocoagulation surgical device, Figure 3 Shown is a schematic diagram of the block diagram of the ciliary photocoagulation surgical device.

[0065] like Figure 3 As shown, similar to the existing related surgical equipment, the ciliary body photocoagulation surgical equipment also includes a control module 210, and a laser light source module 220, a light source transmission module 230 and a display interaction module 240 controlled by the control module 210; The difference is that it also includes a sound sensing module 250 electrically connected to the control module 210. For example, the sound sensing module 250 here is implemented based on a microphone sensor, such as a high-performance MEMS microphone sensor that can be arranged at the end of the laser emitting optical fiber of the device; The control module 210 of the ciliary body photocoagulation surgical device is configured to execute the auxiliary control method described in the above method embodiment on the basis of realizing the existing control functions.

[0066] Furthermore, in some implementation scenarios, the device further includes an audio playback module (not shown in the figure) electrically connected to the control module 210, which is used to implement audio playback output of the indication information under the control of the control module 210. Specifically, in some implementations, the audio playback module includes an earphone component, and for example, the earphone component here may be a wireless Bluetooth earphone.

[0067] The specific content of the auxiliary control method has been described in detail in the embodiments of the method, so it will not be elaborated here.
