Description

Technical Field

[0001] This invention relates to the field of smart healthcare, and more particularly to an intelligent control method and medical endoscopy system for disposable electronic endoscopes. Background Technology

[0002] In the field of smart healthcare, disposable electronic endoscopes, as a means of exploring the human body, have seen rapid technological advancements in recent years. In the past, the vast majority of medical endoscopic instruments were imported from Japan, but with the rise of domestically produced endoscopes and the introduction of domestically made endoscopic modules, the proportion of imported endoscopic products is gradually decreasing. Taking the centralized procurement of urological endoscopes as an example, this will be a crucial segment for the explosive growth of disposable electronic endoscopes in China, requiring continuous innovation from upstream and downstream enterprises and related R&D teams to achieve domestic substitution of imported products.

[0003] However, existing technologies still have shortcomings, such as the difficulty in controlling the usage time of disposable electronic endoscopes. Therefore, this invention proposes an intelligent control method and medical endoscopy system for disposable electronic endoscopes, which can solve the aforementioned problems. Summary of the Invention

[0004] The technical problem solved by this invention is how to design a solution for disposable electronic endoscopes that can ensure the standardized management and control of disposable electronic endoscopes.

[0005] In a first aspect, this application proposes an intelligent control method for a disposable electronic endoscope. The method is used for response interaction between the endoscope and a host device. The endoscope includes a control unit. The intelligent control method includes: S1, determining whether there is a successful response between the endoscope and the host device; S2, if the response is successful, reading a unique ID code and a hash value; S3, the host device uses the unique ID code and hash value as references to determine whether to start the endoscope.

[0006] A further technical solution is that, after step S3, the intelligent control method includes: S4, when the endoscope is started, monitoring whether the real-time parameters of the endoscope meet the preset requirements.

[0007] The inventors discovered through research that in some emerging markets overseas, particularly in developing countries (such as India or Southeast Asia), medical institutions, constrained by procurement budgets and with imperfect systems, sometimes reuse disposable electronic endoscopes intended for single use. This reuse makes it easier to evade medical oversight, and the standardization of operation is difficult to guarantee. Based on this, the solution described in this application is for disposable electronic endoscopes, effectively monitoring the endoscope through preset duration and number of power-on cycles. This ensures the standardized management of disposable electronic endoscopes and avoids non-compliant operations by some medical workers.

[0008] A further technical solution is that the host end is connected to the endoscope via the handle end. The endoscope includes the handle end and a sensor connected to each other. The sensor has a sensing chip and a control unit. Step S1 includes: S11, the control unit determines whether the handle end is connected to the host end and realizes a successful response between the endoscope and the host end.

[0009] A further technical solution is that step S2 includes: S21, if there is a successful response with the host, the host reads the unique ID code in the sensor and the hash value in the sensor.

[0010] A further technical solution is that the host terminal is equipped with a monitoring module, and the control unit is connected to the monitoring module; step S3 includes: S31, the host terminal calculates a first hash result based on the unique ID code and encryption algorithm, and compares the first hash result with the hash value in the sensor; S32, if the comparison fails, the system is locked and no image is displayed; S33, if the comparison succeeds, the monitoring module inside the host terminal is started.

[0011] The further technical solution is as follows: the monitoring module is used to monitor real-time parameters, including a preset duration and / or the number of power-on cycles; the control unit is also connected to a counting unit; step S4 includes: S41, the control unit determines whether a power-on start signal has been received; if a power-on start signal is received and the preset duration monitored in real time by the monitoring module is exceeded, the control unit determines that the preset usage limit of the endoscope has been reached; S42, the control unit determines whether a power-on start signal has been received; if a power-on start signal is received and the preset duration is not exceeded, the number of power-on cycles is accumulated internally by the counting unit; S43, if the result of the number of power-on cycles accumulated internally by the counting unit is greater than the preset power-on limit, it is determined that the preset usage limit of the endoscope has been reached; S44, after the number of power-on cycles corresponding to the counting unit increases by one, it is determined whether the number of power-on cycles has been accumulated to the preset limit; if the result of the number of power-on cycles accumulated internally by the counting unit is not greater than the preset power-on limit, the endoscope function remains in normal state; S45, if the preset usage limit of the endoscope is reached, the host displays a Lock interface.

[0012] A further technical solution is that the power-on count is accumulated internally by the counting unit, including: S51, after receiving a power-on start signal of more than one minute, the control unit determines that it is not a temporary endoscope operation and generates a valid power-on record; S52, the valid power-on record is used as a trigger signal to send a count increment command to the counting unit; S53, the counting unit receives the count increment command and, in response to the command, reads the previously stored historical power-on count from the non-volatile memory; S54, the counting unit performs an increment operation on the historical power-on count to obtain the real-time power-on count, thereby completing the internal accumulation of power-on count.

[0013] The further technical solution is that step S43 includes: if the result of the cumulative number of power-on times through the counting unit is more than 10, it is determined that the preset usage limit of the endoscope has been reached; step S44 includes: after the power-on times corresponding to the counting unit increases by one, it is determined whether the number of power-on times has been accumulated to the preset limit number of times, and if the result of the cumulative number of power-on times through the counting unit is not more than 10, the endoscope is kept in a normal functioning state.

[0014] Secondly, this application proposes a medical endoscope system, comprising an endoscope and a host unit, which interact with each other. The host unit is connected to the endoscope via a handle. The endoscope includes a handle and a sensor connected to each other. The sensor contains a sensing chip, and the sensing chip includes a control unit. The medical endoscope system is used to implement the intelligent control method described in the first aspect. The functions of the medical endoscope system include: first, a limited number of times: once; second, a limited duration: less than or equal to 8 hours; and third, it requires brand manufacturer matching and does not require EEPROM implementation.

[0015] The shortcomings of existing technologies mainly include: First, existing products identify the manufacturer and endoscope by measuring the EEPROM on the handle, but this design is easily copied, allowing endoscopes from other manufacturers to be matched; Second, existing products write back to the EEPROM after marking the number of times / duration, but this can be erased; Third, existing products lack an unrecoverable mechanism once locked. The medical endoscope system proposed in this application, including the endoscope and the host unit, integrates relevant functional modules into the endoscope's sensor chip: On one hand, the checksum key is integrated into the endoscope sensor (inside the sensor) and encrypted using the SHA128 algorithm, making it uncopyable; on the other hand, it is stored inside the sensor instead of relying on the EEPROM, thus making it unrecoverable. Once the product is locked, the efuse key inside the sensor is hardcoded, achieving an unrecoverable mechanism.

[0016] In summary, in the field of smart healthcare, disposable electronic endoscopes, as a means of probing the human body, have seen rapid technological development in recent years. However, existing technologies still have shortcomings, such as the difficulty in controlling the usage time of current disposable electronic endoscopes. Based on this, this application proposes an intelligent control method and medical endoscopy system for disposable electronic endoscopes. This method effectively monitors the endoscope from two aspects: preset duration and number of power-on cycles. It can ensure the standardized management of disposable electronic endoscopes and avoid non-compliant operations by some medical workers. Attached Figure Description

[0028] Example Please see Figures 1 to 3 The image shows an intelligent control method for disposable electronic endoscopes proposed in an embodiment of the present invention. See details... Figure 1 As shown, in a first aspect, this application proposes an intelligent control method for a disposable electronic endoscope. The method is used for response interaction between the endoscope and a host device. The endoscope includes a control unit. The intelligent control method includes: S1, determining whether there is a successful response between the endoscope and the host device; S2, if the response is successful, reading a unique ID code and a hash value; S3, the host device uses the unique ID code and hash value as references to determine whether to start the endoscope.

[0029] In one embodiment, after step S3, the intelligent control method includes: S4, when the endoscope is started, monitoring whether the real-time parameters of the endoscope meet preset requirements.

[0030] In one embodiment, the host end is connected to the endoscope via a handle end. The endoscope includes a handle end and a sensor connected to each other. The sensor has a sensing chip and a control unit. Step S1 includes: S11, the control unit determines whether the endoscope and the host end have successfully responded after the handle end is connected to the host end.

[0031] In one embodiment, step S2 includes: S21, if a successful response is received from the host, the host reads the unique ID code and the hash value from the sensor. The hash value is calculated based on the unique ID code and corresponds to the encryption algorithm. Further, the first hash result can be obtained by calculating the hash using the ID and the key with the encryption algorithm. In this scheme, the brand manufacturer possesses the key; only when both the ID and the key are present can the hash value be calculated. Other manufacturers (competitors) cannot deduce the key if they only obtain the hash value, thus preventing endoscopes from other manufacturers from entering the medical field in an uncompliant manner.

[0032] In one embodiment, the host terminal has an internal monitoring module, and the control unit is connected to the monitoring module. Step S3 includes: S31, the host terminal calculates a first hash result based on the unique ID code and encryption algorithm, and compares the first hash result with the hash value in the sensor; S32, if the comparison fails, the system is locked and no image is displayed; S33, if the comparison succeeds, the monitoring module inside the host terminal is activated. Optionally, the host terminal calculates a first hash result based on the unique ID code and SHA128 algorithm, and compares the first hash result with the hash value in the sensor. In the above scheme, the SHA-256 hash value is calculated based on the read ID and the KEY pre-stored on the host terminal, corresponding to the first hash result.

[0033] In one embodiment, the monitoring module is used to monitor real-time parameters, including a preset duration and / or the number of power-on cycles. The control unit is also connected to a counting unit. Step S4 includes: S41, the control unit determines whether a power-on start signal has been received. If a power-on start signal is received and the preset duration monitored by the monitoring module is exceeded, the control unit determines that the preset usage limit of the endoscope has been reached; S42, the control unit determines whether a power-on start signal has been received. If a power-on start signal is received and the preset duration is not exceeded, the number of power-on cycles is accumulated internally by the counting unit; S43, if the result of the number of power-on cycles accumulated internally by the counting unit is greater than the preset power-on limit, the preset usage limit of the endoscope has been reached; S44, after the power-on cycle corresponding to the counting unit increases by one, it is determined whether the number of power-on cycles has been accumulated to the preset limit. If the result of the number of power-on cycles accumulated internally by the counting unit is not greater than the preset power-on limit, the endoscope function remains in normal state; S45, if the preset usage limit of the endoscope has been reached, the host displays a Lock interface. The increase in the number of power-on cycles is due to an operation performed by a medical worker. This operation can be for temporary scenarios (such as rapid insertion / removal tests) or for actual surgical needs, as those skilled in the art will understand. Furthermore, the host computer displays a Lock interface, meaning that even if the endoscope is initialized after locking, it cannot perform endoscopic image recognition.

[0034] In one embodiment, the step of accumulating the number of power-on cycles internally by the counting unit includes: S51, after receiving a power-on start signal lasting longer than one minute, the control unit determines that it does not belong to a temporary endoscope operation and generates a valid power-on record; S52, using the valid power-on record as a trigger signal, sending a count increment command to the counting unit; S53, the counting unit receives the count increment command and, in response to the command, reads the previously stored historical power-on cycles from the non-volatile memory; S54, the counting unit performs an increment operation on the historical power-on cycles to obtain the real-time power-on cycle count, thereby completing the internal accumulation of the number of power-on cycles.

[0035] In one embodiment, step S43 includes: if the result of the cumulative number of power-on times through the counting unit is more than 10, it is determined that the preset usage limit of the endoscope has been reached; step S44 includes: after the power-on times corresponding to the counting unit increases by one, it is determined whether the number of power-on times has been accumulated to the preset limit number of times, and if the result of the cumulative number of power-on times through the counting unit is not more than 10, the endoscope is kept in a normal functioning state.

[0036] The inventors discovered through research that in some emerging markets overseas, particularly in developing countries (such as India or Southeast Asia), medical institutions, constrained by procurement budgets and with imperfect systems, sometimes reuse disposable electronic endoscopes intended for single use. This reuse makes it easier to evade medical oversight, and the standardization of operation is difficult to guarantee. Based on this, the solution described in this application is for disposable electronic endoscopes, effectively monitoring the endoscope through preset duration and number of power-on cycles. This ensures the standardized management of disposable electronic endoscopes and prevents non-compliant operations by some medical workers.

[0037] Secondly, this application proposes a medical endoscope system, comprising an endoscope and a host unit, which interact with each other. The host unit is connected to the endoscope via a handle. The endoscope includes a handle and a sensor connected to each other. The sensor contains a sensing chip, and the sensing chip includes a control unit. The medical endoscope system is used to implement the intelligent control method described in the first aspect. The functions of the medical endoscope system include: first, a limited number of times: once; second, a limited duration: less than or equal to 8 hours; and third, it requires brand manufacturer matching and does not require EEPROM implementation.
