Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a catheter service life prompting method and device and laser treatment equipment. Background Art

[0002] Laser ablation technology in medicine is a non-invasive or minimally invasive treatment method that mainly uses high-energy laser beams to destroy or remove diseased tissue. For example, ultraviolet laser ablation technology can be used to remove plaques in blood vessels and restore blood flow. Specifically, a fiber optic bundle catheter can be used to transmit ultraviolet high-energy lasers to the lesion site in the vascular cavity. The laser acting on biological tissues will produce a series of biological effects, such as photochemical effects, thermal effects, and mechanical effects. Ultraviolet lasers with high peak power pulses and pulse widths in the nanosecond range have high photon energy, which can directly destroy the chemical bonds between biological tissue molecules and break macromolecular compounds into tiny particles with a volume of less than 20μm, which are eventually absorbed by the reticuloendothelial system, thereby achieving the effect of reducing volume and expanding the lumen.

[0003] Laser catheters have a limited service life, and there are many risks when used beyond their service life. For example, breakage or rupture may cause catheter fragments to remain in the patient's body. Catheter aging may also lead to reduced laser transmission efficiency, and part of the laser energy may be lost in the catheter and unable to effectively act on the target tissue.

[0075] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0076] According to an embodiment of the present invention, an embodiment of a catheter service life prompt method is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of executable computer instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0077] In this embodiment, a catheter service life prompt method is provided, which can be used for laser treatment equipment. The laser treatment equipment can also be called a laser, a laser treatment device, a laser treatment system, etc. Figure 1 is a flow chart of a catheter service life prompting method according to an embodiment of the present invention. Figure 1 As shown, the process includes the following steps:

[0078] Step S101, identifying the identity information of a target catheter, where the target catheter is a laser catheter that has been connected to a laser treatment device. The laser catheter may be a fiber optic catheter.

[0079] Specifically, after the laser treatment device is turned on, it needs to be preheated for a certain period of time, and then the laser catheter is correctly inserted into the catheter interface to complete the correct connection of the laser catheter.

[0080] In some optional specific implementations, step S101, i.e., identifying the identity information of the target catheter, includes:

[0081] Step S1011 , reading tag information from a radio frequency identification (RFID) tag disposed on a target catheter.

[0082] Step S1012: determining the identity information of the target catheter according to the tag information.

[0083] In an embodiment of the present invention, the laser treatment device uses radio frequency identification technology to identify the laser catheter. Specifically, an RFID reader is provided on the laser treatment device, wherein the antenna of the RFID reader may be located above the catheter interface. The RFID tag is integrated into the laser catheter. The RFID tag includes an integrated circuit and an antenna for transmitting data. The RFID reader reads the tag information from the RFID tag provided on the target catheter, and then transmits it to the processor of the laser treatment device to determine the identity information of the target catheter. The operating frequency of the RFID may be low frequency, high frequency or ultra-high frequency.

[0084] In other embodiments, the identity information of the target catheter may be obtained through other short-distance communication methods, or through a QR code, a bar code, or an identity recognition code.

[0085] If the identity information of the target catheter cannot be obtained, corresponding prompt information can be directly output to indicate that the identity information acquisition fails. The specific prompt information can be determined according to actual needs.

[0086] Step S102: If the target catheter is a new catheter, the expected service life of the target catheter is determined according to the identity information of the target catheter.

[0087] Specifically, the identity information may include the model of the target catheter. The expected service life of the target catheter may be determined based on the model of the target catheter. The expected service life of catheters of different models may be pre-stored in the laser treatment device, and after the model of the target catheter is obtained, its expected service life may be determined. The identity information of the target catheter may also directly include its expected service life.

[0088] Step S103, obtaining the current use information of the target catheter. The current use information of the target catheter may include the current use time and may also include the energy density value. The current use information of the target catheter may be determined based on the laser emission control instruction of the laser treatment device. For example, for the current use time of the target catheter, if the foot switch is used to control the triggering of the laser emission control instruction to control the emission and stop of the laser, then the current use time is equal to the time when the current foot switch is pressed (the foot switch is pressed to turn on and released to turn off). The current use information of the target catheter may also be determined based on the actual detection result of the laser energy detector (also called a laser energy meter or a function meter).

[0089] Step S104: determining the current remaining usage time of the target catheter according to the expected service life and the current usage information.

[0090] In some embodiments, the current usage information includes the current usage duration, and determining the current remaining usage duration of the target catheter according to the expected service life and the current usage information includes:

[0091] The current remaining usage time of the target catheter is obtained by subtracting the current usage time from the expected service life.

[0092] That is, the current remaining usage time of the target catheter is the expected service life minus the current usage time.

[0093] In some other embodiments, the current usage information includes a current energy density value and a current usage duration;

[0094] Step S104, i.e. determining the current remaining use time of the target catheter according to the expected service life and the current use information, includes:

[0095] Step S1041, determining the currently consumed service life according to the current energy density value and the current usage time;

[0096] Step S1042, subtract the currently consumed service life from the expected service life to obtain the current remaining service life.

[0097] The greater the energy density value, the faster the life of the catheter will be consumed. In the embodiment of the present invention, when determining the current life of the target catheter, not only the current use time of the target catheter is considered, but also the energy density value when the target catheter is used is considered, which can improve the accuracy of determining the current remaining life of the laser catheter.

[0098] Specifically, a fitting formula can be constructed with energy density and usage time as independent variables and consumed service life as dependent variable, and then the currently consumed service life can be calculated using the formula. A correction parameter can also be determined according to the energy density value range to which the current energy density value belongs, and then the correction parameter is multiplied by the current usage time to obtain the currently consumed service life.

[0099] In other embodiments, when determining the currently consumed service life, the current usage time may be corrected based on the temperature of the conduit to obtain the currently consumed service life.

[0100] Among them, the current energy density value can be the current energy density setting value of the laser treatment device. Specifically, the laser treatment device can provide multiple energy density value options, which are displayed on the display screen for users (generally doctors) to choose from, and then the energy density value corresponding to the energy density value option selected by the user is used as the current energy density value, and the laser treatment device emits the laser according to the current energy density value (specifically, the expected value of the laser energy is first calculated based on the current energy density value, and then the laser energy output value is obtained by adding the loss of laser energy transmission to this expected value, and the laser treatment device controls the emission of the laser according to this laser energy output value). For example, the energy density values ​​corresponding to the energy density value options available for users to choose may be: 40mJ / mm 2 、50mJ / mm 2 、60mJ / mm 2 The multiple energy density value options provided by the laser therapy device may be fixed or determined according to the model of the laser catheter, that is, if the models of the connected laser catheters are different, then at least some of the energy density value options provided by the laser therapy device may be different (different energy density value options correspond to different energy density values).

[0101] In some other optional specific implementations, after identifying the identity information of the target catheter, the method further includes:

[0102] Step 1: If the target catheter is not a new catheter, the historical usage information or the historical remaining usage time of the target catheter is obtained according to the identity information. The historical usage information is the usage information of the target catheter used before, including the usage time, and the temperature, energy density value, etc. The historical remaining usage time is the remaining usage time of the target catheter after the last use of the target catheter. Specifically, the identity information also includes indication information for indicating whether the target catheter is a new catheter, and the target catheter can be judged whether it is a new catheter according to the indication information. The indication information can also be stored in the laser treatment device, and can also be stored in other devices (such as cloud devices, etc.) that are connected to the laser treatment device for communication. At this time, the indication information can be obtained from the laser treatment device or other devices according to the identity information (for example, including the unique identification information of the catheter) to determine whether the target catheter is a new catheter. In addition, the historical usage information or the historical remaining usage time of the target catheter can also be stored in the laser treatment device or other devices. The indication information indicating whether the target catheter is a new catheter is updated after the new catheter is used for the first time, and the historical usage information or the historical remaining usage time is updated after each use of the catheter.

[0103] Step 2: Determine the current remaining usage time of the target catheter based on the historical usage information or the historical remaining usage time and the current usage information. Specifically, the currently consumed service life time can be determined based on the current usage information; then, the currently consumed service life time is subtracted from the historical remaining usage time to obtain the current remaining usage time; or, determine the first remaining usage time based on the historical usage information, and subtract the currently consumed service life time from the first remaining usage time to obtain the current remaining usage time.

[0104] Step S105, displaying remaining usage time indication information in the middle of the display screen of the laser treatment device.

[0105] Step S106: display the current usage information next to the remaining usage time indication information.

[0106] The laser treatment device includes a display device, which can be independent of the laser treatment device host or integrated with the laser treatment device, and the display device includes a display screen. While displaying the remaining usage time indication information on the display screen, the remaining usage time indication information can also be output in the form of voice broadcast.

[0107] In the embodiment of the present invention, during the use of the laser catheter, the service life of the catheter is automatically counted down visually, and the countdown indication information, i.e., the remaining use time indication information, is displayed in the middle area of ​​the display screen. The current energy density value and the current use time can also be displayed at the same time. The displayed information is not limited to these, and can also include the historical use information of the target catheter, the historical use information includes the previous use information and / or the total time of historical use (total used time), the previous use information includes the use time of the target catheter in previous uses, the energy density value when the target catheter is used in previous uses, and the model, name, and identity code of the target catheter can also be displayed. Among them, the previous use information of the target catheter can be displayed in the form of a list next to the remaining use time indication information, and the displayed content includes the serial number of the previous uses, the use time, the energy density when used, etc. Specifically, the embodiment of the present invention can record the use time of the laser catheter each time and the number of laser emissions after the foot switch is stepped on in the form of a list, which can facilitate the doctor to make an indirect judgment on the surgical situation based on the data.

[0108] In some optional specific implementations, the remaining usage time indication information includes dynamic numbers and / or dynamic patterns that change with the current remaining usage time. Specifically, the dynamic numbers are countdown numbers. The dynamic pattern can be a ring pattern, and the countdown number can be located in the middle of the ring pattern (when the dynamic number and the ring pattern are displayed simultaneously). The width of the ring pattern narrows as the current remaining usage time decreases, and / or the color of the ring pattern changes as the current remaining usage time decreases. For example, the width of the ring pattern decreases in proportion as the current remaining usage time decreases. When the current remaining usage time is greater than or equal to the preset time, the color of the ring pattern is blue, and when the current remaining usage time is less than the preset time, the color of the ring pattern changes to yellow. The dynamic pattern can also be a ring timeline, and as the current remaining usage time decreases, the color of the ring timeline changes to another color in proportion. The dynamic pattern can also be an hourglass, a clock, a linear timeline, etc. The remaining usage time indication information can also include text-based indication information, or a pop-up prompt box, etc.

[0109] The remaining usage time indication information provided by the embodiment of the present invention can more intuitively remind the user of the remaining usage time of the laser catheter.

[0110] The catheter service life prompt method provided in this embodiment automatically identifies the target catheter to obtain its expected service life, then automatically deducts the current service life consumption to obtain the remaining use time, and displays the remaining use time indication information, so that the doctor can intuitively understand the remaining service life of the catheter when using the laser treatment equipment, without having to evaluate the remaining service life of the laser catheter by himself. This can not only avoid the risks brought by the over-service life use of the laser catheter, but also allow the doctor to concentrate on the treatment operation.

[0111] In some optional specific implementation manners, the method provided by the embodiment of the present invention further includes:

[0112] Obtain the detection result of the target catheter and output the detection result.

[0113] In the embodiment of the present invention, the use of the catheter is detected in real time by laser technology, including the wear and aging of the catheter, and the corresponding detection results are output. Similarly, the output of the detection results is in the form of display screen display, voice broadcast, etc., so as to avoid the effect of laser treatment affected by the wear and aging of the catheter, resulting in harm to the patient.

[0114] In some optional specific implementations, the embodiments of the present invention calibrate the target catheter according to the following method:

[0115] Step 1, obtain the test energy density value. The test energy density value can be the default value of the laser therapy device, specifically, it can be the middle value of the energy density values ​​that can be set for the laser therapy device. For example, the energy density values ​​that can be set for the laser therapy device are 40mJ / mm², 50mJ / mm², and 60mJ / mm², so the test energy density value is set to 50mJ / mm². Use the middle value of the energy density value that can be set for the laser therapy device as the test energy density value. Even if other energy density values ​​are set later to control the emission of the laser, the deviation will not be too large.

[0116] Step 2: Determine the corresponding first laser energy output expected value according to the model of the target catheter and the test energy density value.

[0117] Specifically, when the target catheter is a fiber optic catheter, the expected value of the first laser energy output can be calculated according to the following formula:

[0118] The expected value of the first laser energy output = the test energy density value × 3.14 × D × D / 4 × the number of optical fibers; where D is the diameter of a single optical fiber. The diameter and number of optical fibers of a single optical fiber can be determined according to the model of the target catheter. In other words, after knowing the model of the target catheter, the diameter and number of optical fibers of a single optical fiber can be known.

[0119] Step 3: Control the emission of a test laser according to the first laser energy output expected value to obtain the corresponding first laser energy output actual value. The laser energy output actual value (including the first laser energy output actual value, the second laser energy output actual value, the third laser energy output actual value, etc.) can be detected by a laser energy detector (also called a laser energy meter or a function meter).

[0120] Step 4: output a first calibration result of the target catheter based on the first laser energy output expected value and the first laser energy output actual value; the first laser energy output actual value is a laser energy value detected at the laser output end of the target catheter.

[0121] In an embodiment of the present invention, the laser catheter is calibrated before the laser treatment device is officially operated. The calibration result (e.g., the first calibration result) may include indication information indicating whether the target catheter calibration has passed or failed, and may also include the catheter transmission efficiency of the target catheter. The catheter transmission efficiency may be calculated by dividing the actual value of the laser energy output (e.g., the first actual value of the laser energy output) by the laser energy value (e.g., the first expected value of the laser energy output) on which the laser treatment device controls the emission of the laser. Of course, the catheter transmission efficiency in the calibration result may be replaced by the laser energy loss rate, or may include the laser energy loss rate at the same time, which is calculated by subtracting the actual value of the laser energy output (e.g., the first actual value of the laser energy output) from the laser energy value (e.g., the first expected value of the laser energy output) on which the laser treatment device controls the emission of the laser (e.g., the first expected value of the laser energy output) to obtain the laser energy value (i.e., the lost laser energy value) divided by the laser energy value (e.g., the first expected value of the laser energy output) on which the laser treatment device controls the emission of the laser.

[0122] Regarding the judgment of whether the target catheter calibration passes or fails, the first catheter transmission efficiency can be calculated based on the first laser energy output expected value and the first laser energy output actual value; if the first catheter transmission efficiency meets the first preset condition, it is determined that the target catheter calibration passes, otherwise the calibration fails. Specifically, the first preset condition can be within a set range or in a magnitude relationship with a preset threshold. For example, if the first catheter transmission efficiency is the value obtained by dividing the first laser energy output actual value by the first laser energy output expected value, then the target catheter calibration passes when the first catheter transmission efficiency is greater than the preset threshold, otherwise the calibration fails. Of course, it is also possible to judge whether the calibration passes or fails based on the laser energy loss rate. If the laser energy loss rate is the value obtained by subtracting the first laser energy output actual value from the first laser energy output expected value and then dividing it by the first laser energy output expected value, then the target catheter calibration passes when the laser energy loss rate is less than or equal to the preset threshold, otherwise the calibration fails.

[0123] In addition, the reason for the calibration failure can also be output. If the actual value of the first laser energy output is zero, the reason for the output calibration failure is that the laser energy output is not detected. If the actual value of the first laser energy output is not zero, but the first catheter transmission efficiency does not meet the threshold requirement, then the reason for the output calibration failure is that the catheter output laser energy efficiency is too low.

[0124] In some other optional specific embodiments, in addition to the above calibration of the target catheter, further calibration of the target catheter (i.e., laser energy output deviation calibration) may also be included. Specifically, based on the first laser energy output expected value and the first laser energy output actual value, after outputting the first calibration result of the target catheter, the method further includes:

[0125] Step 1: If the first calibration result of the target catheter is that the calibration is passed, then according to the first catheter transmission efficiency, the laser energy output value is increased on the basis of the first laser energy output expected value to obtain a second laser energy output value; the first catheter transmission efficiency is calculated based on the first laser energy output expected value (for example, A) and the first laser energy output actual value (for example, B).

[0126] For example, the expected value of the first laser energy output is A, and the actual value of the first laser energy output is B. Then the first catheter transmission efficiency C is equal to B / A, and accordingly, the second laser energy output value is D (A / C).

[0127] Step 2: Control the emission of the laser according to the second laser energy output value D, and obtain the corresponding second laser energy output actual value E.

[0128] Step 3: Based on the second laser energy output actual value E and the first laser energy output expected value A, determine whether a preset laser output deviation requirement is met.

[0129] Specifically, the laser output deviation can be obtained by first subtracting the second laser energy output actual value E from the first laser energy output expected value A, and then dividing the result by the first laser energy output expected value A. This deviation is considered to meet the preset laser output deviation requirement within a certain range, for example, within ±5%.

[0130] Step 4: When it is determined that the preset laser output deviation requirement is met, determine that the calibration is passed and output a corresponding second calibration result.

[0131] Specifically, in addition to information indicating whether the calibration is passed or not, the second calibration result may also include a second catheter transmission efficiency, where the second catheter transmission efficiency F is calculated based on the second laser energy output actual value E and the second laser energy output value D, that is, F=E / D.

[0132] Step 5: When it is determined that the preset laser output deviation requirement is not met, the laser energy output value is increased to a third laser energy output value G (D / F) based on the second laser energy output value according to the second catheter transmission efficiency; the second catheter transmission efficiency is calculated based on the second laser energy output actual value and the second laser energy output value.

[0133] Step six: controlling the laser to be emitted according to the third laser energy output value G, and obtaining the corresponding third laser energy output actual value H.

[0134] Step 7: Based on the third laser energy output actual value H and the first laser energy output expected value, determine whether the preset laser output deviation requirement is met. For the specific judgment process, please refer to the above process of determining whether the preset laser output deviation requirement is met based on the second laser energy output actual value E and the first laser energy output expected value A.

[0135] Step eight: if it is determined based on the third laser energy output actual value that the preset laser output deviation requirement is met, determine that the calibration is passed; otherwise, determine that the calibration fails, and output the corresponding third calibration result.

[0136] In addition to including information indicating whether the calibration passed or failed, the third calibration result may also include the reason for the calibration failure, such as no laser energy output detected, low output laser energy efficiency, etc.

[0137] After the target catheter is calibrated, the laser emission can be controlled as follows:

[0138] Step 1: Get the current energy density value set by the user.

[0139] Step 2: Determine the corresponding second laser energy output expected value according to the model of the target catheter and the current energy density value. The calculation method of the second laser energy output expected value can refer to the calculation method of the first laser energy output expected value above.

[0140] Step 3: Determine a fourth laser output value according to the catheter transmission efficiency of the target catheter and the expected value of the second laser energy output.

[0141] The catheter transmission efficiency of the target catheter is obtained by calibration. The catheter transmission efficiency indicates the laser energy loss rate. When only the catheter transmission efficiency calibration is performed without the laser energy output deviation calibration, the catheter transmission efficiency can be calculated as follows: the first laser energy output actual value B divided by the first laser energy output expected value A, that is, the first catheter transmission efficiency mentioned above. The third laser output value is calculated in a similar manner to the second laser energy output value, which is the second laser energy output expected value I / C (C=B / A). When both the catheter transmission efficiency calibration and the laser energy output deviation calibration are performed, when the calibration is determined to be passed based on the second laser energy output actual value, the catheter transmission efficiency is the first catheter transmission efficiency. When the calibration is determined to be passed based on the third laser energy output actual value H, the catheter transmission efficiency is the second catheter transmission efficiency, F=E / D. The fourth laser energy output value is: the second laser energy output expected value I / F.

[0142] Step 4: Control the emission of laser according to the fourth laser energy output value.

[0143] In the embodiment of the present invention, considering that the laser will be partially lost during the transmission process of the laser catheter, and the loss rate will be different due to different laser energy values ​​transmitted in the catheter, the embodiment of the present invention first calibrates the laser catheter, which is used to determine whether the laser energy at the output end of the laser catheter is within a reasonable range after the laser emits laser according to the control instruction, and also to determine the laser energy transmission efficiency. Then, according to the laser energy demand of the laser treatment target position (that is, the energy demand at the output end of the laser catheter, which is specifically determined according to the laser energy density setting value and the number of optical fibers of the optical fiber catheter, the diameter of a single optical fiber, etc.) and the catheter transmission efficiency of the laser energy, the energy control value when the laser emits the laser is reversed, so that the energy at the output end of the laser catheter can meet the demand (not exceeding ±5%).

[0144] In an embodiment of the present invention, after the power-on setting is turned on, the laser therapy device is turned on, preheated for a certain period of time, and then the laser catheter is correctly inserted into the catheter interface to complete the correct connection of the laser catheter. The identity information of the laser catheter (such as the model of the catheter) is identified through radio frequency identification technology. Before the laser catheter starts working, the laser catheter is calibrated. After the calibration is passed, an instruction is selected based on the user's laser energy density value to determine the energy density setting value of the laser therapy device. The "Ready" button is displayed, and after the user clicks the "Ready" button, the laser therapy device is ready to be prepared. When the system pop-up window prompts that it is ready, the user clicks the "Confirm" button on the pop-up window. The display interface switches from the system pop-up window to the display interface for outputting the remaining usage time indication information (such as Figure 2After receiving the instruction triggered by the foot switch being stepped on, the laser therapy device outputs laser according to the energy density setting value, and the remaining usage time begins to count down. The remaining usage time indication information (including dynamic countdown numbers and dynamic ring patterns) changes accordingly (as shown in the figure below). Figure 3 When the remaining usage time is less than the preset time, the color of the dynamic ring pattern turns yellow (as shown in Figure 4 The remaining usage time indication information display interface also displays the energy density setting value, the current usage time of the laser catheter, historical usage information, etc. In addition, the usage of the laser catheter is detected in real time before and during the operation of the laser catheter. During the operation of the laser catheter, that is, during the laser emission, any operation on the display interface is prohibited. Even if there is an operation, the laser treatment device will not respond.

[0145] The target catheter's identity information (including model, batch number, identification code, etc.), previous usage information (energy density setting value, usage duration, etc.), and catheter detection results during use can all be stored in the database corresponding to the laser treatment device. The database can be a local database or a cloud database, making it easy to check the catheter's usage.

[0146] In some optional specific implementation manners, the embodiments of the present invention further include:

[0147] In response to the user's screening input, some or all of the historical usage information of the laser catheter is displayed, the laser catheter including the target catheter or excluding the target catheter.

[0148] Specifically, Figure 5 As shown, for example, according to the model of the laser catheter, the usage of different catheters of the same model can be filtered and viewed, and the usage information of the catheter and other data can also be filtered based on the date.

[0149] In addition, the embodiments of the present invention can also perform data analysis on the catheter, for example, the expected service life of the catheter can be updated to make it more accurate, which can avoid waste of the catheter and rupture of the catheter caused by over-use of the life span.

[0150] At the same time, because each laser catheter is linked to different patient information and can correspond to different patients according to the access time of the catheter, the stored catheter information can facilitate doctors to view the catheter data later and provide data support for other research and clinical practice.

[0151] For example, the information of the patient who is treated with the laser treatment device each time can be stored in the database, so that the patient's treatment information can be obtained, including the energy density setting value and usage time of the laser treatment device.
