[0061] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings 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 ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0062] Combine the following Figure 1-Figure 10 The invention describes a medical consumable, a medical device and a laser ablation system.

[0063] Figure 1 is one of the structural schematic diagrams of the medical consumables provided by the present invention, such as Figure 1 As shown, the medical consumable 200 includes a slender component body 210 and coding information 220, wherein the coding information 220 corresponds to the consumable attribute information.

[0064] For different usage scenarios, the slender component body 210 can be the body of a slender medical consumable used in the corresponding scenario, such as an optical fiber used to transmit laser to perform target tissue ablation in a laser ablation system, an optical fiber used to transmit laser to irradiate photosensitizers in photodynamic therapy, a radio frequency electrode in a radio frequency ablation system, a cortical electrode in an electroencephalographic monitoring system, a stimulation electrode in an electrical stimulation system, a microwave needle (microwave antenna) in a microwave ablation system, a water vapor ablation needle in a water vapor ablation system, a balloon catheter in a cryoablation system, a puncture needle in a chemical ablation system, and the like.

[0065] The coding information 220 corresponds to the consumables attribute information, such as the consumables manufacturer, consumables model, medical device unique identification, production date, production batch number, consumables size, applicable temperature range, adaptable medical device model and other attribute information.

[0066] In some embodiments, the coding information 220 may be generated by direct coding based on the consumables attribute information, for example, the first 3 digits of the "coding" correspond to the manufacturer of the consumables, 4 to 7 digits correspond to the production date of the consumables, 8 to 9 digits correspond to the performance data of the consumables (such as size specifications, use temperature), etc. It can be understood that at this time, the consumables attribute information is obtained by decoding based on the "direct coding" combined with the "coding rules". In order to facilitate the acquisition of the consumables attribute information corresponding to the coding information, the "coding rules" can be stored for the decoding process, or the direct coding information can be associated with the consumables attribute information and stored.

[0067] In some embodiments, the coding information 220 may be a non-repeating random number assigned to each medical consumable produced, such as a random number of 6 or more digits, and the random number (coding information) is associated with the consumable attribute information and stored for easy query.

[0068] Based on any of the above embodiments, in one embodiment, the encoding information 220 is a sequence of characters, or a graphic code.

[0069] Specifically, the coded information 220 can be a sequence of characters (letters, numbers, punctuation marks, operators, etc.), which are convenient for users to observe and enter through input devices, thereby improving verification efficiency. The coded information in the form of a character sequence can also be obtained by collecting images and extracting them from the images in combination with optical character recognition (OCR). The coded information 220 can also be in the form of a graphic code, such as a barcode, a QR code, a black and white code, a color code, etc. The graphic code can be scanned and identified by a dedicated scanning device, or it can be identified after the image is collected by an image acquisition device.

[0070] Based on the above embodiments, in one embodiment, the consumable attribute information includes at least one of the following: manufacturer, consumable model, medical device unique identification, production date, production batch number, consumable size, applicable temperature range, and adaptable medical device model.

[0071] Specifically, the coded information 220 may correspond to one or more of the above-mentioned specific consumables attribute information, which is convenient for verifying whether the consumables meet the use standards and match the medical equipment. For example, it is used to verify whether the maximum transmission power of the optical fiber is greater than the power of the laser device, and for another example, to verify whether the excitation band of the microwave ablation needle and the power supported by the consumables match the microwave source device (such as a magnetron microwave source, a solid-state microwave source), etc.

[0072] Still refer to Figure 1 Based on any of the above embodiments, in one embodiment, the medical consumable 200 further includes an identification strip 230 , which is connected to the slender member body 210 , and the coding information 220 is provided on the identification strip 230 .

[0073] Specifically, the identification strip 230 is printed or engraved with coding information 220, and the identification strip 230 is connected to the slender component body 210. The specific connection method may be that the identification strip 230 is axially pasted on the slender component body 210, or that it is pasted on the slender component body 210 in a "U" shape fold, or that one end of the identification strip 230 (overlapping) is pasted on the slender component body 210. The present invention does not limit the method in which the identification strip 230 is connected to the slender component body 210.

[0074] This embodiment adds coding information to medical consumables at a low cost through the identification strip, thereby reducing the cost of medical consumables and medical devices. The coding information on the identification strip can be used to easily obtain consumable attribute information, thereby improving verification efficiency and reducing the burden on doctors.

[0075] Reference Figure 2Based on the above embodiment, in one embodiment, the medical consumable 200 further includes a consumable connector 240, which is used to connect to the output interface of the medical device to obtain the output energy or ablative agent. The coding information 220 of the medical consumable 200 is set on the consumable connector 240, for example, the coding information 220 is printed / engraved / embossed on the consumable connector 240, or a label sticker is attached to the consumable connector 240 of the medical consumable 200, and the sticker has the coding information 220.

[0076] Still refer to Figure 2 Based on any of the above embodiments, in one embodiment, the optical fiber assembly 200 includes an optical fiber connector 240, which is connected to one end of the optical fiber 210. The optical fiber connector 240 is used to connect the optical fiber to the output interface of the optical generation module to obtain laser energy.

[0077] In one solution, the optical fiber connector includes a near-field wireless communication module 250, and the coding information 220 is stored in the near-field wireless communication module 250. In another solution, the optical fiber connector 240 includes a storage chip 250, and the coding information 220 is stored in the storage chip 250. After the output interface of the optical generating module is connected to the optical fiber connector 240, the coding information 220 stored in the storage chip 250 can be read. In another solution, the optical fiber connector 240 includes a series of dip switches 250, for example, 6, 7, 8 (or more) dip switches, and the switch states of the series of dip switches 250 correspond to a binary sequence, and the binary sequence corresponds to the coding information 220. Preferably, the above-mentioned dip switches 250 can be distributed on the periphery of the laser outlet of the output interface, so that the dip switches 250 do not affect the transmission of the laser.

[0078] In this embodiment, a near-field wireless communication module or a storage chip or a dial switch is provided in the optical fiber connector to store coding information accordingly, so that the coding information can be automatically collected after the user connects to the optical fiber, thereby improving convenience.

[0079] Reference Figure 3 Based on the above embodiment, in one embodiment, the medical consumable 200 further includes a connector protection cap 290, which is used to be installed on the consumable connector 240. The connector protection cap 290 can protect the consumable connector 240 from dust when the consumable is not in use. When in use, the connector protection cap 290 can be removed and then the consumable connector 240 can be connected to the medical device.

[0080] Furthermore, the connector protection cap 290 may be a nut (preferably a hexagonal nut). The threaded portion of the nut may be screwed and fixed to the optical fiber connector 240 to prevent loosening and falling off, and to play a role in dust prevention.

[0081] Further, still refer to Figure 3, the joint protection cap 290 is connected to one end with a hanging belt 291, and the other end of the hanging belt 291 is connected to the slender member body 210. When the joint protection cap 290 is removed, the joint protection cap 290 can be hung on the slender member body 210 through the hanging belt 291 to prevent the joint protection cap 290 from being lost and also prevent the joint protection cap 290 from being stuck with dust. The other end of the hanging belt 291 can be fixedly connected to the slender member body 210, or can be movably connected to the slender member body 210, for example, the other end of the hanging belt 291 is provided with a ring structure, which is sleeved on the slender member body 210 through the ring structure.

[0082] Based on the above embodiments, in one embodiment, the medical consumable 200 further includes a protective structure, and the coded information 220 cannot be obtained if the protective structure is not destroyed or removed.

[0083] Specifically, the protective structure is set on the coded information 220, such as a scrapeable coating (such as a silk-screen ink coating) covering the coded information 220; the protective structure is also such as an opaque film (such as a PP material film with a pressure-sensitive adhesive coated on one side) pasted on the coded information 220; for another example, the coded information 220 is set on the optical fiber connector 240 (surface or inside), in this case, the protective structure can be a film covering the optical fiber connector 240; the protective structure is also such as a mechanical structure (such as a flip cover, a destructible pull ring, etc.) covering the coded information 220. The coded information 220 can only be obtained (collected) after the protective structure is destroyed or removed.

[0084] In this embodiment, the coding information is protected by a protective structure, and the coding information can only be obtained after the protective structure is destroyed or removed, so that the user cannot obtain the coding information at will, thereby preventing surgical risks caused by replacing and using medical consumables, and preventing infection risks caused by reusing medical consumables.

[0085] The present invention further provides a medical consumables kit, which includes a disposable sterile bag and medical consumables 200. The medical consumables 200 are sealed in the disposable sterile bag.

[0086] Specifically, in some usage scenarios, the elongated member body 210 (or a portion of the elongated member body 210) needs to contact or be implanted in the human body to perform operations, and therefore needs to meet certain sterility standards. By sterilizing the medical consumables 200 and sealing them in a disposable sterile bag, the medical consumables can be sterilely protected and the risk of infection can be reduced.

[0087] Figure 5 is a schematic diagram of the structure of a medical device provided by the present invention, such as Figure 5 As shown, the medical device includes: any of the aforementioned medical consumables 200, and a processing module 300.

[0088] The processing module 300 is configured to:

[0089] S11, obtaining the coding information of the medical consumables;

[0090] S12, querying the coding information in the database, if the coding information is not found, executing S21, if the coding information is found, executing S22;

[0091] S21, outputting a first prompt message;

[0092] S22. Obtain first consumable material attribute information corresponding to the coding information.

[0093] Specifically, the medical consumables 200 have coding information 220, and the processing module 300 obtains the coding information for processing. According to different ways of setting the coding information in the medical consumables 200, there may be different ways of obtaining the coding information. For example, the coding information is a character sequence set on the medical consumables 200, and the user observes the coding information and inputs the coding information through an input device (keyboard, mouse, touch screen, voice input port, etc.), and the processing module 300 receives the coding information from the input device; for another example, the coding information is a character sequence or a graphic code (barcode, QR code; black and white code, color code, etc.) set on the medical consumables 200, and the collection device (such as CCD scanner, laser scanner, mobile phone, camera, etc.) collects the coding information, and then the processing module 300 processes the collected information to obtain the coding information in a character form that is convenient for computer processing; for another example, the coding information is the coding information stored in the chip in the medical consumables or the coding information corresponding to the dial switch, and the coding information is obtained through the configured reading circuit and transmitted to the processing module 300.

[0094] The database stores the coding information and the consumables attribute information corresponding to each coding information in association. The database can be a local database of the processing module 300 or a cloud database. The processing module 300 searches the database for coding information. If the coding information is not found, S21 is executed to output the first prompt information, such as "consumables (optical fiber / RF electrode, balloon catheter, etc.) are unqualified", "unknown consumables", "no consumables information found", and other related prompt contents. If the coding information is found, S22 is executed to obtain the first consumables attribute information corresponding to the coding information.

[0095] This embodiment sets coding information in medical consumables, so that doctors can easily collect or enter coding information when using medical consumables, and then automatically obtain various attribute information of the consumables from the database for verification based on the coding information. It can efficiently and accurately identify whether the medical consumables are suitable for the current medical device, without the need for doctors to memorize / check / compare complex consumable attribute information, thereby improving the verification efficiency of medical consumables and reducing the workload of doctors.

[0096] It can be understood by those skilled in the art that the processing module 300 can adopt a general computer architecture and implement the above configuration content by loading computer instructions. Specifically, the processing module 300 includes a memory and a processor, and the processor executes the computer instructions stored in the memory to implement the above configuration content. Those skilled in the art also know that in addition to implementing the processing module 300 by loading a computer program in a general computer architecture, it is entirely possible to make separate integrated circuit modules according to each step of its implementation, and each integrated circuit module is used as a component of a hardware component to implement the processing module 300, or an integrated circuit module can be made according to some of the steps of its implementation and combined with a software module that implements other steps to implement the processing module 300. Therefore, the processing module 300 can also be implemented as a hardware component, or as a combination of a software module and a hardware component.

[0097] Based on the above embodiment, in one embodiment, the coded information includes a check bit, and the processing module 300 is further configured to:

[0098] After S11, the coded information is checked according to the check bit to see if it is qualified;

[0099] If unqualified, output the second prompt information;

[0100] If qualified, jump to execute S12.

[0101] Specifically, a check bit is also set in the coding information, and the value of the check bit in the coding information is associated with the values ​​of other bits. After obtaining the coding information, the processing module 300 can calculate the exact value of the check bit according to the verification rule. If the actual value of the check bit does not match the exact value, it means that the consumables verification is unqualified, and the second prompt information is output at this time, such as outputting prompt information with relevant contents such as "verification failed", "consumables unqualified", "please replace consumables", etc.

[0102] In this embodiment, by setting a check bit in the coding information and executing the check step through the processing module, the medical consumables can be quickly and preliminarily verified. If the actual value of the check bit is consistent with the accurate value, it means that the coding information of the medical consumables complies with the coding rules, and subsequent steps can be executed, such as executing subsequent inspection steps, allowing access to medical consumables, etc.

[0103] This embodiment can quickly and preliminarily verify medical consumables by setting a check bit in the coded information, and preliminarily eliminate consumables that are not suitable for medical devices.

[0104] Based on any of the above embodiments, in one embodiment, after S22, the method further includes:

[0105] S23, obtaining target consumables attribute information required by the medical device, and determining whether the first consumables attribute information matches the target consumables attribute information; if not, executing S24; wherein the target optical fiber attribute information is determined according to the surgical plan or input by the user;

[0106] S24: Output the third prompt information.

[0107] Specifically, the processing module 300 also obtains target consumables attribute information required by the medical device, such as connector specifications, consumables size, supported power, etc. The target consumables attribute information can be automatically extracted from the surgical plan, such as extracting the current surgical type, the power of the expected transmission energy, the consumables implantation depth, the use temperature, etc. The target optical fiber attribute information can also be input by the user, such as the user inputting the required optical fiber model, manufacturer, etc. The processing module 300 determines whether the first consumables attribute information matches the target consumables attribute information. If it does not match, it means that the consumables do not meet the use requirements of the medical device. At this time, the third prompt information is output for prompting, such as outputting prompt contents such as "unqualified consumables", "consumables do not support transmission power", "please replace consumables", etc.; if it matches, further subsequent actions are performed, such as performing subsequent inspection steps, allowing access to medical consumables, etc.

[0108] In this embodiment, by obtaining the target consumables attribute information of the device and comparing it with the first consumables attribute information, it is accurately and efficiently determined whether the consumables match the medical device. In the case of mismatch, a prompt is also given to facilitate the doctor to replace the appropriate medical consumables. The target consumables attribute information can be manually input by the user to reduce product costs, or it can be automatically extracted from the surgical plan to improve the intelligence of the matching process and improve safety.

[0109] Reference Figure 6 Based on any of the above embodiments, in one embodiment, the system also includes an ablation module 400 connected to the medical consumable 200, and the ablation module 400 is used to generate ablation energy and output energy through the medical consumable 200, and / or output ablative agent through the medical consumable 200.

[0110] For example, in a laser ablation scenario, the medical consumable 200 is an optical fiber, and the ablation module 400 is a laser. The laser generates laser light and introduces it into the target area through the optical fiber for ablation; in a radio frequency ablation scenario, the medical consumable 200 is a radio frequency electrode, which punctures the target area, and the ablation module 400 is a radio frequency generator, which generates radio frequency energy and outputs radio frequency energy to the target area through the radio frequency electrode; in a microwave ablation scenario, the medical consumable 200 is a microwave ablation needle (microwave needle / microwave antenna), and the ablation module 400 is a microwave source (such as a magnetron microwave source, a solid-state microwave source), and the ablation module 400 generates microwave energy and introduces it into the target area through the microwave ablation needle; in a cryoablation scenario, the medical consumable 200 is a balloon catheter, which punctures the target area, and the ablation module 400 is a cryoablation instrument, which outputs (and recovers) liquid nitrogen, nitrous oxide, argon, carbon dioxide and other refrigerants to the balloon catheter. The target area is frozen through a balloon catheter, and the target cells are caused to undergo apoptosis by a sudden drop in temperature, or a heating agent (such as helium or other media) is used to achieve alternating hot and cold ablation of the target area, or other modules are used to output energy to improve the ablation effect on the basis of freezing. In the water vapor ablation scenario, the medical consumable 200 is a water vapor ablation needle, and the ablation module 400 is a steam generator. In the chemical ablation scenario, the medical consumable 200 is a puncture needle, which punctures the target area, and the ablation module 400 is a chemical ablation device, which outputs a chemical ablation agent (such as anhydrous ethanol, glacial acetic acid, etc.) to the target area through the puncture needle to perform chemical ablation on the target area. In the photodynamic therapy scenario, the medical consumable 200 is a transmission optical fiber, and the ablation module 400 is a laser. The laser generates laser light and is introduced into a specific position through an optical fiber to irradiate the photosensitive drug accumulated in the lesion, thereby activating the photosensitive drug and destroying the lesion tissue.

[0111] On this basis, the processing module 300 is communicatively connected with the ablation module 400 (wired or wirelessly), and the processing module 300 is also configured to: when the medical consumables are unqualified, control the output interface of the ablation module 400 to pop out / prevent the consumables from being connected, and / or prevent the ablation module 400 from emitting energy / outputting ablative agents to the medical consumables 200.

[0112] Specifically, the processing module 300 will output a prompt message (refer to the aforementioned embodiment) when detecting abnormal coding information. At the same time, the processing module 300 also controls "preventing the output of energy or ablative agent to the target area". The processing module 300 can control the output interface of the ablation module 400 to pop out medical consumables / prevent access to medical consumables, waiting for input or collection of new coding information. For example, a controlled elastic structure is provided in the output interface of the ablation module 400, and the connected medical consumables can be ejected under the control of the processing module 300. For another example, the output interface of the ablation module 400 is provided in a certain shell socket, and a controlled "door structure" is also provided at the socket. The processing module 300 can control the opening / closing of the "door structure", thereby controlling "whether medical consumables are allowed to pass through the shell socket and connect to the output interface of the ablation module". The processing module 300 can also prevent the ablation module 400 from emitting energy or outputting ablative agent to medical consumables, for example, by cutting off the power supply of the ablation module 400, or by prohibiting the processing module 300 from sending a control signal to output energy to the ablation module 400.

[0113] The ablation module 300 can be integrated with the processing module 400 in the same device (e.g., in a trolley), or it can be a separate component. In addition, the processing module 400 here can be a part of the medical device host, that is, the processing module 400 is also used to assist the minimally invasive ablation process; the processing module 400 can also be an independent module connected to the medical device host, such as a mobile phone, notebook, PDA, etc., which obtains the attribute information of the medical consumables or further verifies the medical consumables, and then transmits the relevant information to the medical device host.

[0114] In this embodiment, ablation energy or ablative agent is provided by the ablation module, which provides an ablation basis for the ablation target area. The processing module 300 also pops up / prevents the ablation module 400 from outputting ablation energy or ablative agent while outputting prompt information, automatically blocking the ablation process, avoiding the surgical process from being performed in the case of misuse of consumables, and improving the safety of the operation.

[0115] Based on any of the above embodiments, in one embodiment, after S22, the step further includes, after the operation is completed, associating and recording the operation-related content with the coding information.

[0116] Specifically, if the coding information can be queried in the database, the surgery-related content will be recorded in association with the coding information after the surgery is completed. For example, for laser ablation surgery, the surgery type, laser signal record, laser power, fiber control record (fiber depth, angle), ablation status record and other information will be recorded in association with the coding information to facilitate the tracing of consumables usage and retrospective research.

[0117] Based on any of the above embodiments, in one embodiment, after S22, the step further includes marking the coding information as "used" in the database.

[0118] Specifically, each time the consumables are queried and used, the coding information of the medical consumables is marked as "used". When the medical consumables are used subsequently and the same coding information is used for query, the "used" mark of the coding information will be used to prompt "the consumables have been used", "the consumables are unqualified", "please replace the consumables", or the output interface of the ablation module 400 can be controlled to prevent the consumables from being connected (waiting for new coding information to be input), and the ablation module 400 can also be prevented from emitting energy or outputting ablative agents (such as prohibiting the processing module 300 from sending a control signal to the ablation module 400 to output energy / ablative agents, cutting off the power supply of the ablation module 400, etc.). Alternatively, each time a query is made, the coding information is only queried within the range that is not marked as "used", and the coding information will not be found in the database at this time. This can effectively prevent the reuse and substitution of medical consumables, and improve surgical safety.

[0119] Based on any of the above embodiments, in one embodiment, the database includes each coding information and consumables attribute information corresponding to each coding information.

[0120] Specifically, the database contains coding information and consumable attribute information corresponding to each coding information. It can be understood that the consumable attribute information can be measured and recorded by the consumable manufacturer during the production process, and the coding information can be a generated random code or a code generated according to certain coding rules based on the consumable attribute information.

[0121] Based on any of the foregoing embodiments, in some embodiments, the database is a local database or a cloud database.

[0122] Specifically, the database may be a local database managed by the processing module 300, which can directly perform local queries; the database may also be a cloud database, and the processing module 300 accesses the cloud database through the network to perform queries, which facilitates unified management.

After the consumable connector 240 is connected to the output interface 260, the reading circuit 270 can obtain coding information from the consumable connector 240.

[0124] In one exemplary embodiment, the consumable connector 240 includes a near-field wireless communication module 250, and the reading circuit 270 serves as another near-field wireless communication module, and the two are connected by wireless communication. Specifically, the reading circuit 270 and the near-field wireless communication module 250 can both work in a "point-to-point mode", and the two communicate to obtain coded information, or the reading circuit 270 works in a "reader mode", and the near-field wireless communication module works in a "card mode", and the reading circuit 270 obtains the coded information from the "card"; in another exemplary embodiment, the consumable connector 240 includes a storage chip 250, and the storage chip 250 in the consumable connector 240 is, for example, a flash memory chip, an EEOROM chip, etc., and the consumable connector 24 After the medical consumables 240 is connected to the output interface 260 of the ablation module 400, the medical consumables can transmit the energy generated by the ablation module 400, and the reading circuit 270 is also connected to the storage chip 250, and the reading circuit 270 can also read the coded information stored in the storage chip 250; in another exemplary solution, the consumables connector 240 includes a series of dip switches 250, and the switch states of the series of dip switches 250 correspond to a binary sequence, which corresponds to the coded information. After the consumables connector 240 is connected to the output interface of the ablation module 400, the dip switches 250 are connected to the reading circuit 270, and the reading circuit 270 can obtain the state of the dip switches 250 and obtain the coded information. The reading circuit 270 is connected to the processing module 300 by wire or wirelessly, and transmits the obtained coded information to the processing module.

[0125] In this embodiment, a storage chip or a rotary switch is set in the consumable connector, and a reading circuit is set at the output interface of the output ablation module. When the consumable connector is connected to the output interface of the ablation module, not only can the ablation energy or ablative agent be transmitted, but the coding information can also be automatically acquired, thereby improving the efficiency of the process of verifying medical consumables.

[0126] Reference Figure 8 Based on any of the above embodiments, in one embodiment, the system further includes an input module 500 connected to the processing module 300 , and the coding information obtained in S11 is input by the user through the input module 500 after observing the medical consumables 200 .

[0127] Specifically, the input module 500 is, for example, a keyboard, a mouse, a touch screen, a voice input port, etc., and the input module 500 is connected to the processing module 300 by wire or wirelessly. The processing module 300 receives and obtains the coded information from the input device. After observing the coded information, the user inputs the coded information through the input module 500, and the input module 500 transmits the coded information to the processing module 300.

[0128] In this embodiment, the coding information is obtained at a low cost through the input module in cooperation with the user's "entry" operation, which reduces the product cost of the medical device while ensuring the efficiency of verifying consumables.

[0129] Reference Fig. 9 Based on any of the above embodiments, in one embodiment, the system further includes a collection module 600 that is communicatively connected to the processing module 300 , and the coding information obtained in S11 is obtained by the collection module 600 from the medical consumables 200 .

[0130] Specifically, the acquisition module 600 can acquire coded information based on optics. For example, if there is coded information in the form of a barcode on the medical consumables 200, the acquisition module 600 can be a barcode scanning device such as a CCD scanner, a laser scanner, a light pen scanner, or a mobile phone, which can acquire an image or waveform signal of the barcode, and then transmit the acquired signal to the processing module 300, which extracts and decodes the information to obtain coded information in the form of characters recognizable by a computer; for another example, if there is coded information in the form of a QR code on the medical consumables 200, the acquisition module 600 is an image acquisition device such as a mobile phone or a camera, and the acquisition module 600 can acquire a QR code image, and then the processing module 300 decodes the QR code image to obtain coded information in the form of characters recognizable by a computer; for another example, if there is coded information in the form of characters on the medical consumables 200, the acquisition module 600 is an image acquisition device such as a mobile phone or a camera, and the acquisition module 600 can acquire an image of the characters, and then the processing module 300 processes the character image based on optical character recognition (OCR) to obtain coded information in the form of characters recognizable by a computer.

[0131] In this embodiment, the coding information is collected conveniently and quickly through the collection module, which improves the efficiency of entering the coding information and helps to quickly verify whether the medical consumables meet the usage requirements.

[0132] Reference Fig.10 , based on the above embodiments, in one embodiment, the ablation module 400 includes an output interface 260 for accessing medical consumables, and the output interface 260 or a preset distance range of the output interface 260 is provided with a detection component 280 and a collection module 600;

[0133] After the detection component 280 detects the medical consumables, the processing module 300 controls the acquisition module 600 to acquire the coding information 220 .

[0134] Specifically, the output interface of the ablation module 400 is also provided with a detection component 280 and a collection module 600. The detection component 280 can detect the access action or access status of the medical consumables. After the detection component 280 detects the medical consumables, it transmits the signal to the processing module 300, and the processing module 300 controls the collection module 600 to collect the coded information. The detection component 280 and the collection module 600 can also be set within a preset distance range of the output interface 260. For example, the ablation module 400 is integrated in the operating trolley, and the output interface 260 of the ablation module 400 is set on the shell of the operating trolley. The detection component 280 and the collection module 600 are set on the shell and are within a preset distance from the output interface 260. The specific value of the above-mentioned preset distance is flexibly set according to the size of the relevant hardware, so that the detection component 280 can detect the access action or access status of the medical consumables.

[0135] In this embodiment, the detection component can detect the action of connecting to medical consumables or the connection status of medical consumables, which facilitates the automatic collection of coding information of medical consumables, reduces the workload of doctors, and improves the efficiency of inspecting medical consumables.

[0136] Based on any of the above embodiments, in one embodiment, the detection component 280 is a photoresistor disposed in the output interface 260. After the output interface 260 is connected to a medical consumable, the light intensity in the interface decreases, the resistance value of the photoresistor changes, and the electrical signal of the circuit where the photoresistor is located changes, thereby sensing that the medical consumable is connected.

[0137] This embodiment detects the access status of medical consumables automatically at low cost and with high sensitivity, making it convenient to obtain the coding information of the medical consumables.

[0138] Based on any of the above embodiments, in one embodiment, the detection component 280 is a sensor disposed in the output interface 260 or within the first preset distance range of the output interface 260, such as an infrared distance sensor, a laser distance sensor, an ultrasonic distance sensor, and other distance sensors. When the distance sensor detects a "close distance" signal, it is determined that a medical consumable is being connected or has been connected, and the coded information can be collected by the collection module 600. For another example, the detection component is a pressure sensor in the output port. When the consumable connector is connected to the output connector of the ablation module 400, the pressure sensor detects a changing pressure signal, and determines that a medical consumable is being connected or has been connected. Preferably, the pressure sensor can be a capacitive pressure sensor.

[0139] Based on any of the above embodiments, in one embodiment, the medical device includes an ablation module 400, which is used to generate and output energy through the medical consumable 200, and / or to output an ablative agent through the medical consumable 200; the detection component 280 is a switch arranged on the output interface 260 of the ablation module 400, and the circuit state of the switch changes after the medical consumable is connected.

[0140] The switch may be a contact switch. For example, the output interface 260 of the ablation module 400 is provided with a normally open contact. After the consumable connector 240 is connected to the output interface 260 of the ablation module 400, the contact is pressed together, and the circuit where the normally open contact is located detects a change in the electrical signal, confirming that the consumable is connected (or the output interface 260 is provided with a normally closed contact. After the consumable connector is connected, the normally closed contact on the output interface 260 is disconnected, and a change in the electrical signal is detected); for another example, the output interface 260 of the ablation module 400 is provided with a plug contact. After the consumable connector 240 is connected to the output interface 260 of the ablation module 400, the conductive pin on the consumable connector 240 connects the plug contact, and the circuit where the plug contact is located detects a change in the electrical signal, confirming that the medical consumable is connected.

[0141] The switch can also be a contactless switch, such as a capacitive, inductive, eddy current, or other type of proximity switch. When the medical consumable 200 approaches a certain distance range, a switch signal can be output, and the processing module determines the access status of the medical consumable based on the switch signal.

[0142] Based on any of the above embodiments, in one embodiment, the acquisition module 600 is an image acquisition device or a scanning device arranged within the output interface or within the second preset distance range of the output interface.

[0143] Specifically, the acquisition module 600 may be a miniature image acquisition device or scanning device in the output interface 260, or an image acquisition device or scanning device set within the second preset distance range of the output interface 260. For example, the ablation module 400 is integrated in the operating table, the output interface 260 of the ablation module 400 is set on the shell of the operating table, and the acquisition module 600 is set on the shell and within the preset distance from the output interface 260. The image acquisition device is, for example, a camera, etc., and the scanning device is, for example, a CCD scanner, a laser scanner, etc. By setting the miniature camera at the output interface of the ablation module 400 or within the preset distance range of the output interface, the coded information on the medical consumables 200 can be easily collected during the process of connecting the medical consumables.

[0144] This embodiment uses an image acquisition device or a scanning device set within the ablation module output interface or within the second preset distance range of the output interface to automatically acquire the coding information of medical consumables without additional operation by the user, thereby improving the convenience of the verification process of medical consumables. The camera occupies less space and avoids interference with other components.

[0145] Based on any of the foregoing embodiments, in one embodiment, the medical device is specifically a laser ablation system, the medical consumables are optical fibers, and the ablation module is a laser.

[0146] Specifically, the laser ablation system is also called a laser interstitial thermal therapy system, which uses optical fiber to direct the light energy output by the laser (i.e., the ablation module mentioned above) into the target tissue, and uses the thermal effect of the laser to heat the target tissue. As the output light energy time increases, the temperature of the target tissue increases, and eventually reaches the temperature required for thermal ablation, thereby eliminating the lesion. The laser is connected to the processing module 400 by wire or wirelessly, and outputs the required form of laser according to the control signal of the processing module 400, such as adjusting the excitation current of the laser / adjusting the duty cycle of the pulsed laser, and for example, selecting to output a certain wavelength of laser / outputting a mixed wavelength of laser, etc.

[0147] Optical fiber needs to be implanted in the human body, such as the head, during laser ablation. It is a Class III medical device with high requirements for safety and performance stability, and is used as a consumable in laser ablation. The optical fiber carries coded information, and the processing module of the laser ablation system verifies the coded information of the optical fiber to determine whether the optical fiber meets the use requirements. The setting form of the coded information and the verification process of the processing module can refer to the above-mentioned embodiment, and will not be repeated here.

[0148] Based on any of the above embodiments, in a preferred embodiment, the laser ablation system further includes: a cooling circulation component, a foot switch, and a display module.

[0149] Specifically, the front end of the slender member body 210 needs to be implanted in the body to perform thermal ablation on the target tissue, and the optical fiber needs to be cooled by a cooling circulation assembly to avoid local overheating of the optical fiber. The cooling circulation assembly may include a peristaltic pump, a cooling sleeve, a connecting pipeline, and a cooling medium. The peristaltic pump is used to provide circulation power for the cooling medium. The front end of the optical fiber is placed in the cooling sleeve and implanted in the human body. The cooling medium is pumped by the peristaltic pump and transported to the cooling sleeve through the connecting pipeline. After absorbing the heat of the optical fiber in the cooling sleeve, it flows out from the outlet of the cooling sleeve.

[0150] The foot switch can control the output of the ablation module 400 and adjust the output laser energy. The display module is used to display a graphical interface, specifically, it can display the patient's medical image, three-dimensional model, real-time monitored temperature status, ablation status, etc., and can also display a human-computer interaction interface for the user to input instructions. It can be understood that when the display module is a touch screen, the display module also serves as an input module of the system.

[0151] Based on any of the above embodiments, in one embodiment, the laser ablation system further includes an optical fiber driving module, which is communicatively connected with the processing module, and adjusts the depth, rotation angle and other position states of the optical fiber according to the control instructions of the processing module 300, or adjusts the movement speed, rotation speed and other motion states of the optical fiber, thereby adjusting the light output position and light output angle of the end of the optical fiber to achieve accurate and conformal ablation of the lesion. The ablation action of the optical fiber can be controlled outside a certain range without interrupting the magnetic resonance monitoring process. Preferably, the optical fiber driving module adjusts the optical fiber through a cable, and the cable passes through the wall of the magnetic resonance room and the control room. The patient and the end of the optical fiber are located in the magnetic resonance room, which is convenient for collecting the magnetic resonance image of the patient during the operation. The laser ablation system host (control interface) is located in the control room and "remotely adjusts" the optical fiber through the optical fiber driving module. The doctor can achieve precise adjustment of the optical fiber in the control room without entering the magnetic resonance room to manually adjust the optical fiber, and without interrupting the magnetic resonance monitoring process, thereby improving the efficiency of the operation.
