[0042] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described clearly and completely in conjunction with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0043] Combine the following Figure 1-Figure 7 The utility model describes a therapeutic optical fiber, a therapeutic optical fiber component, a therapeutic system and a laser ablation system.

[0044] Figure 1 This is one of the structural schematic diagrams of the therapeutic optical fiber provided by the utility model, such as Figure 1 As shown, the treatment optical fiber 200 includes an optical fiber body and verification information 230. The optical fiber body includes a transmission section 210 and a treatment end 220. The treatment end 220 is used to output a desired form of treatment laser, and the verification information is used to obtain corresponding optical fiber attribute information.

[0045] The proximal end of the optical fiber transmission segment 210 (i.e., the end close to the laser module and away from the target area to be treated) can be connected to the laser module to transmit laser energy to the treatment end 220. In some application scenarios (such as laser beauty), the treatment end 220 directly emits laser from the end face. In some application scenarios (such as laser interstitial thermal therapy), the treatment end 220 is implanted into the target area, and the treatment end 220 emits laser from the side wall to treat the surrounding target area. Specifically, the treatment end 220 can be a scattered light-emitting end (which can emit light in a circumferential direction), a directional light-emitting end (which emits light along a certain circumferential range), or a composite light-emitting end (the optical fiber contains multiple cores, and each core can emit light in a certain direction range). The treatment end 220 emits laser to treat the target area. The treatment optical fiber 200 also includes verification information 230, which can be directly set on the optical fiber body (i.e., the transmission segment 210 and the treatment end 220), or on a component connected to the optical fiber body.

[0046] The corresponding fiber attribute information can be obtained through the verification information 230, such as the fiber manufacturer, fiber model, medical device unique identifier, production date, production batch number, fiber length, ablation tip length, maximum transmission power, allowable bending radius, allowable tension, allowable side pressure, operating temperature range, fiber loss, outer diameter, number of fiber cores, applicable laser equipment model and other attribute information. It can be understood that different types of treatment optical fibers correspond to different verification information, and the verification information is set on the optical fiber. When using the treatment optical fiber, by obtaining the verification information on the optical fiber for query, the optical fiber attributes can be obtained efficiently, accurately and comprehensively to confirm whether the optical fiber meets the use requirements of the treatment device.

[0047] This embodiment outputs a laser that meets the usage requirements through the treatment end, and sets verification information on the provided treatment optical fiber. The doctor can easily obtain the verification information when using the optical fiber, and then automatically obtain a variety of optical fiber properties corresponding to the verification information, confirm whether it is an optical fiber compatible with the laser equipment, and whether the optical fiber matches the surgical plan to be performed, thereby improving the verification efficiency of the optical fiber, reducing the doctor's workload, and avoiding the incorrect use of the optical fiber.

[0048] In some embodiments, the verification information 230 may be directly coded and generated according to the fiber attribute information, for example, the first 3 digits of the "code" correspond to the manufacturer of the fiber, 4-7 digits correspond to the production date of the fiber, 8-9 digits correspond to the maximum transmission power of the fiber, etc. The verification information 230 may also be a non-repeating random number generated for each fiber, such as a random number of 6 or more digits, and the random number (verification information) is associated with the fiber attribute and stored for query.

[0049] Based on the previous embodiment, in one embodiment, the treatment tip 220 is a scattering tip or a side-shooting tip.

[0050] In a scenario where it is necessary to emit laser light through the side wall to treat the target area, such as a laser ablation scenario, the treatment tip 220 may be a scattering tip or a side-shooting tip.

[0051] The scattering tip can modulate the direction of the laser so that it is diffusely emitted circumferentially, so that the ablation power around the tip is more uniform. The structure of the scattering tip, for example, is to dope scattering particles or scattering bubbles in the scattering tip, and use the scattering particles or scattering bubbles to scatter the laser around the tip; for another example, a circumferential reflection surface is set in the scattering tip to reflect the laser around the treatment tip 220. A specific example is to set a conical reflection surface in the treatment tip 220, with the bottom of the cone facing the end face of the treatment tip 220, and the laser is reflected by the conical surface and emitted from the surrounding side walls of the treatment tip 220. The scattering tip can scatter the laser uniformly.

[0052] The side-firing terminal can modulate the direction of the laser so that it is emitted along one side of the treatment terminal (or diverges along one side within a certain angle range). The side-firing terminal can ablate tissue in a single direction. By controlling the angle and depth of the optical fiber, "conformal ablation" can be achieved for complex shapes. A specific example of a side-firing terminal is to place a reflective surface obliquely inside the treatment terminal 220 to reflect the laser to one side (or with a certain divergence angle).

[0053] Still refer to Figure 1 Based on the above embodiments, in one embodiment, the treatment optical fiber includes a label strip 240 connected to the optical fiber body, and the label strip is provided with verification information 230.

[0054] Specifically, the label strip 240 is printed or engraved with verification information 230, and the label strip 240 is connected to the optical fiber body (i.e., the transmission section 210 and the treatment end 220). The specific connection method may be that the label strip 240 is pasted on the optical fiber body along the axial direction of the optical fiber, or that it is pasted on the optical fiber body in a "U" shape folding manner, or that one end of the label strip 240 (overlapping) is pasted on the optical fiber body. The utility model does not limit the method in which the label strip 240 is connected to the optical fiber body.

[0055] This embodiment adds verification information to the treatment optical fiber at a low cost through the label strip, thereby reducing the cost of the treatment optical fiber and the laser treatment system. The optical fiber properties can be easily obtained through the verification information on the label strip, which improves the verification efficiency and reduces the burden on doctors.

[0056] Reference Figure 2Based on any of the above embodiments, in one embodiment, the treatment optical fiber 200 further includes an optical fiber connector 250, which is disposed at the proximal end of the transmission section 210. The optical fiber connector 250 is used to connect to the laser output interface of the laser module to obtain the output laser. The verification information 230 of the treatment optical fiber 200 is disposed on the optical fiber connector 250, for example, the verification information 230 is printed / engraved / embossed on the optical fiber connector 250, or a label sticker is attached to the optical fiber connector 250, and the sticker has the verification information 230.

[0057] In this embodiment, verification information is set on the optical fiber connector at one end of the optical fiber. The optical fiber connector provides sufficient space for the verification information, so that the verification information can be set more obviously and more convenient to collect.

[0058] Still refer to Figure 2 Based on the above embodiment, in one embodiment, the treatment optical fiber 200 further includes a connector protection cap 290, which is used to be installed on the optical fiber connector 250. The connector protection cap 290 can protect the optical fiber connector 250 from dust when the optical fiber is not in use. When in use, the connector protection cap 290 can be removed, and then the optical fiber connector 250 can be plugged into the output interface of the laser module.

[0059] 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 250 to prevent loosening and falling off, and to play a role in dust prevention.

[0060] Further, refer to Figure 3 , the connector 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 transmission section 210. When the connector protection cap 290 is removed, the connector protection cap 290 can be hung on the transmission section 210 through the hanging belt 291 to prevent the connector protection cap 290 from being lost and also prevent the connector protection cap 290 from being stuck with dust. The other end of the hanging belt 291 can be fixedly connected to the transmission section 210, or it can be movably connected to the transmission section 210, for example, the other end of the hanging belt 291 is provided with a ring structure, which is sleeved on the transmission section 210 through the ring structure.

[0061] Based on any of the above embodiments, in one embodiment, the verification information 230 is a sequence of characters or a graphic code.

[0062] Specifically, the verification information 230 may 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 input device may be a keyboard, an interactive interface displayed on a touch screen, etc. The verification information in the form of a character sequence may also be obtained by capturing an image and extracting it from the image in combination with optical character recognition (OCR). The verification information 230 may 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 may be scanned and identified by a dedicated scanning device, or may be identified after an image is captured by an image acquisition device.

[0063] Reference Figure 4 Based on any of the above embodiments, in one embodiment, the treatment optical fiber 200 further includes an optical fiber connector 250, which is connected to the proximal end of the transmission section 210. The optical fiber connector 250 is used to connect the optical fiber to the output interface of the laser module to obtain laser energy.

[0064] In one solution, the optical fiber connector includes a near-field wireless communication module 260, and the verification information 230 is stored in the near-field wireless communication module 260. In another solution, the optical fiber connector 250 includes a storage chip 260, and the verification information 230 is stored in the storage chip 260. After the output interface of the laser module is connected to the optical fiber connector 250, the verification information 230 stored in the storage chip 260 can be read. In another solution, the optical fiber connector 250 includes a series of dip switches 260, for example, 6, 7, 8 (or more) dip switches, and the switch states of the series of dip switches 260 correspond to a binary sequence, and the binary sequence corresponds to the verification information 230. Preferably, the above-mentioned dip switches 260 can be distributed on the periphery of the laser outlet of the output interface, so that the dip switches 260 do not affect the transmission of the laser.

[0065] In this embodiment, by setting a near-field wireless communication module or a storage chip or a DIP switch in the optical fiber connector to store verification information, the verification information can be automatically collected after the user connects to the optical fiber, thereby improving convenience.

[0066] Based on the above embodiment, in one embodiment, a protection structure is further included. If the protection structure is not destroyed or removed, the verification information 230 cannot be obtained.

[0067] Specifically, the protective structure is set on the verification information 230, such as a scrapeable coating (such as a silk-screen ink coating) covering the verification information 230; 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 verification information 230; for another example, the verification information 230 is set on the optical fiber connector 250 (surface or inside), in which case the protective structure can be a film covering the optical fiber connector 250; the protective structure is also such as a mechanical structure covering the verification information 230 (such as a flip cover, a destructible pull ring, etc.). The verification information 230 can only be obtained (collected) after the protective structure is destroyed or removed.

[0068] In this embodiment, the verification information is protected by a protective structure, and the verification information can only be obtained after the protective structure is destroyed or removed, so that the user cannot obtain the verification information at will, thereby preventing surgical risks caused by replacing the optical fiber and infection risks caused by reusing the optical fiber.

[0069] Based on the above embodiments, in one embodiment, the optical fiber attributes include at least one of the following: manufacturer, optical fiber model, unique identification of medical device, production date, production batch, maximum transmission power, allowable bending radius, allowable tension, allowable side pressure, operating temperature range, optical fiber loss, outer diameter, number of fiber cores, and applicable laser equipment model.

[0070] Specifically, the verification information 230 can correspond to one or more of the above-mentioned specific optical fiber properties, which is convenient for verifying whether the optical fiber meets the usage standards and whether it matches the laser equipment. For example, it can be used to verify whether the maximum transmission power of the optical fiber is greater than the power of the laser equipment, whether the outer diameter of the optical fiber matches the laser output interface of the laser equipment, etc.

[0071] The utility model also provides an optical fiber assembly for laser treatment, wherein the optical fiber assembly comprises a disposable sterile bag and any one of the aforementioned treatment optical fibers 200, wherein the treatment optical fiber 200 is sealed in the disposable sterile bag.

[0072] Specifically, in some use scenarios, the optical fiber 210 needs to be implanted in the human body to perform operations, and therefore needs to meet certain sterility standards. By sterilizing the optical fiber and sealing it in a disposable sterile bag, the optical fiber can be sterilely protected and the risk of infection can be reduced.

[0073] The utility model also provides a laser ablation system. The laser ablation system described below and the therapeutic optical fiber described above can refer to each other.

[0074] Figure 5 This is one of the structural diagrams of a treatment system provided by the utility model, such as Figure 5 As shown, the laser ablation system includes: a laser module 300 , an input device 400 and a host 500 .

[0075] The laser module is used to connect to any of the aforementioned treatment optical fibers 200 to output treatment laser;

[0076] The input device is used to input the verification information of the treatment optical fiber;

[0077] The host is connected to the input device to query the verification information and output the fiber attribute information.

[0078] Specifically, the treatment optical fiber 200 is used to connect the laser module 300 during the treatment process, and transmit the laser generated by the laser module 300 to the part to be treated. The laser module 300 can be connected to the host 500 by wire or wirelessly. For example, the laser module 300 is a laser, which is connected to the host 500 by a cable; for another example, the laser 300 is a laser equipped with a communication unit, which is wirelessly connected to the host 500 through the communication unit. The laser module 300 outputs the required form of laser according to the control signal of the host 500, such as adjusting the excitation current of the laser module 300 / adjusting the duty cycle of the pulsed laser, and for another example, selecting a laser of a certain wavelength, etc. Of course, the laser module 300 may not be connected to the host 500, and the user manually controls the working state of the laser module 300. A series of optical fibers adapted to the treatment system are all provided with verification information, and different types (or different individuals) of optical fibers are provided with different verification information. The input device 400 obtains the verification information and sends it to the host 500 for processing, thereby outputting the optical fiber attribute information. According to different ways of setting verification information in the treatment optical fiber 200, there can be different ways of entering verification information. For example, the verification information is a character sequence set on the treatment optical fiber 200. After observing the verification information, the user enters the verification information through the input device 400 (keyboard, mouse, touch screen, voice input port, etc.), and the host 500 receives the verification information from the input device; for another example, the verification information is a character sequence or graphic code (barcode, QR code; black and white code, color code, etc.) set on the treatment optical fiber 200. The input device (such as CCD scanner, laser scanner, mobile phone, camera, etc.) collects the verification information, and then the host 500 processes the collected information to obtain the verification information in character form that is easy for the computer to process; for another example, the verification information is the chip storage or the code corresponding to the dip switch in the optical fiber connector 250, and the verification information is obtained through the configured reading circuit (input device 400) and transmitted to the host 500.

[0079] It is understandable that the connection between the host 500 and the input device 400 refers to a communication connection. The components of the treatment system (laser module 300, input device 400, host 500 and other modules) can be partially or completely integrated together, for example, the laser module 300, the host 500 and the input device 400 are integrated into the operating trolley; for another example, the host 500 and the input device 400 are set together, and the laser module 300 is set independently (more specifically, for example, the operating trolley includes a host and a camera scanner, and for another example, the host is a tablet computer or a mobile phone, which also includes a touch screen input or a camera scan as an input device, and the two are integrated into one); for another example, the input device 400 is integrated into the laser module 300 to detect the verification information on the optical fiber, and the host 500 is set independently. The utility model does not limit the combination form and specific form of each component.

[0080] This embodiment sets verification information in the treatment optical fiber, efficiently obtains the verification information through the input device, and uses the host to automatically output accurate and comprehensive optical fiber attribute information. It can automatically, efficiently and accurately identify whether the optical fiber is suitable for the current laser equipment. There is no need for the doctor to remember / check / compare complex optical fiber attributes, which improves the efficiency of optical fiber verification and reduces the workload of doctors.

[0081] It will be understood by those skilled in the art that the host 500 may adopt a general computer architecture to implement its "query, output" functions by loading computer instructions. Specifically, the host 500 includes a memory and a processor, and the processor executes computer instructions stored in the memory to implement the above functions. The implementation method is a general technology and will not be repeated here.

[0082] Based on the previous embodiment, in one embodiment, the treatment system further includes a display module.

[0083] The host 500 can display the property information of the optical fiber through the display module, such as the manufacturer, optical fiber model, maximum transmission power, number of fiber cores, operating temperature range, etc., and can further display relevant prompt information based on the optical fiber property information, such as "the optical fiber does not match the treatment device", "unknown optical fiber, please replace", "the optical fiber does not meet the use requirements", etc. The display module can also be used to display the patient's medical images, three-dimensional models, real-time monitoring of the temperature status of the patient's tissue, 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.

[0084] Based on the previous embodiment, in one embodiment, the laser module 300 further includes a blocking unit for realizing one or more of the following functions: cutting off the power supply of the laser module 300, cutting off the laser output optical path, blocking the access optical fiber, or ejecting the already accessed optical fiber.

[0085] Specifically, when it is identified that the optical fiber does not meet the use requirements, the blocking unit can prevent the output of the laser by manual control or under the control of the host. For example, the blocking unit is a switch set at the power supply of the laser module 300, which can cut off the power supply; for another example, the blocking unit is a controlled optical element, which can cut off the optical path of the laser output to the optical fiber; for another example, the blocking unit is a blocking structure set at the output interface of the laser module 300, and whether the access to the optical fiber is allowed is controlled by opening / closing the blocking structure. For another example, the blocking unit is a mechanical structure set at the output interface of the laser module 300, which can eject the optical fiber that has been connected to avoid erroneous operation. In addition, the host 500 can also be configured to prevent the laser module 300 from emitting laser when confirming that the optical fiber part meets the use requirements, such as prohibiting the host 500 from sending a control signal to the laser module 300 to output the laser.

[0086] Furthermore, the host 500 can also be configured to match the fiber attribute information with the surgical plan information, such as the type of surgery, the selected laser wavelength, the type of ablation fiber scattering head (scattering fiber, directional fiber, composite fiber), laser power, ablation temperature, etc. When the fiber attribute does not match the surgical plan, a prompt message can be output to improve the safety of the surgery.

[0087] Reference Figure 6 Based on any of the above embodiments, in one embodiment, the treatment optical fiber 200 includes an optical fiber connector 250, the optical fiber connector 250 includes a near-field wireless communication module or a storage chip or a dip switch 260, the laser module 300 includes an output interface 270, and the output interface 270 includes a reading circuit 280. After the optical fiber connector 250 is connected to the output interface 270, the reading circuit 280 can obtain verification information from the optical fiber connector 260.

[0088] In the first solution, the optical fiber connector 250 includes a near-field wireless communication module 260, and the reading circuit 280 serves as another near-field wireless communication module, and the two are connected by wireless communication. Specifically, the reading circuit 280 and the near-field wireless communication module 250 can both work in "point-to-point mode", and the two communicate to obtain verification information, or the reading circuit 280 works in "reader mode", and the near-field wireless communication module works in "card mode", and the reading circuit 280 obtains verification information from the "card"; in the second solution, the optical fiber connector 250 includes a storage chip 260, and the storage chip 260 in the optical fiber connector 250 is, for example, a flash memory chip, an E EOROM chip, etc. After the optical fiber connector 250 is connected to the output interface 270 of the laser module 300, the reading circuit 280 is connected to the storage chip 260 to read the verification information stored in the storage chip 250; in the third scheme, the optical fiber connector 250 includes a series of dip switches 260, and the switch states of the series of dip switches 260 correspond to a binary sequence, which corresponds to the verification information. After the optical fiber connector 250 is connected to the output interface 270 of the laser module 300, the dip switches 260 are connected to the reading circuit 280, and the reading circuit 280 can obtain the state of the dip switches 260 and obtain the verification information. The reading circuit 280 is connected to the host 500 by wire or wirelessly, and transmits the obtained verification information to the host 500.

[0089] In this embodiment, a storage chip or a rotary switch is set in the optical fiber connector, and a reading circuit is set at the output interface of the laser module, so that after the optical fiber connector is connected with the output interface of the laser module, not only can the laser energy be transmitted, but also the verification information can be automatically obtained, thereby improving the efficiency of the optical fiber verification process.

[0090] Based on any of the above embodiments, in one embodiment, the input device 400 is a manual input device, such as a keyboard, a mouse, a touch screen, a voice input port, etc., and the input device 400 is connected to the host 500 by wire or wirelessly. After observing the verification information, the user inputs it into the input device, and the input device transmits the verification information to the host 500.

[0091] In this embodiment, verification information is obtained at a low cost through the manual input device in cooperation with the user's "entry" operation, which reduces the product cost of the treatment system while ensuring the efficiency of the verification optical fiber.

[0092] Based on any of the above embodiments, in one embodiment, the input device 400 is an automatic scanning device. For example, if there is verification information in the form of a barcode on the treatment optical fiber 200, the input device 400 can be a barcode scanning device such as a CCD scanner, a laser scanner, a light pen scanner, or a mobile phone, which can collect the image or waveform signal of the barcode, and then transmit the collected signal to the host 500, which extracts and decodes the information to obtain the verification information in the form of characters that can be recognized by the computer; for another example, if there is verification information in the form of a QR code on the treatment optical fiber 200, the input device 400 is an image scanning device such as a mobile phone or a camera, which can collect the QR code image, and then the host 500 decodes the QR code image to obtain the verification information in the form of characters that can be recognized by the computer; for another example, if there is verification information in the form of characters on the treatment optical fiber 200, the input device 400 is an image scanning device such as a mobile phone or a camera, which can collect the image of the characters, and then the host 500 processes the character image based on optical character recognition (OCR) to obtain the verification information in the form of characters that can be recognized by the computer.

[0093] In this embodiment, verification information is collected conveniently and quickly through a scanning device, which improves the efficiency of entering verification information and helps to quickly verify whether the optical fiber meets the usage requirements.

[0094] Reference Figure 7 Based on the above embodiments, in one embodiment, the system further includes a detection component, which can detect the access action or access status of the treatment optical fiber, and communicate so that the input device automatically collects verification information.

[0095] Specifically, in one example, the output interface 270 of the laser module 300 is also provided with a detection component 271 and an input device 400, the detection component 271 can detect the access action or access status of the optical fiber, and after the detection component 271 detects the optical fiber, it transmits the signal to the host 500, and the host 500 controls the input device 400 to collect verification information, or the detection component 271 directly transmits the signal to the input device 400, and the input device collects verification information according to the signal. The detection component 271 and the input device 400 can also be arranged within a preset distance range of the output interface 270, for example, the laser module 300 is integrated in the operating trolley, the (laser) output interface 270 of the laser module 300 is arranged on the housing of the operating trolley, and the detection component 271 and the input device 400 are arranged on the housing, and are within a preset distance from the output interface 270. The specific value of the above-mentioned preset distance is flexibly set according to the size of the associated components, so that the detection component 271 can detect the access action or access status of the optical fiber.

[0096] In this embodiment, the detection component can detect the action of connecting to the optical fiber or the optical fiber connection status, which is convenient for automatically collecting the verification information of the optical fiber, reduces the workload of the doctor, and improves the efficiency of inspecting the optical fiber.

[0097] Based on any of the above embodiments, in one embodiment, the detection component 271 is a photoresistor arranged in the output interface 270. After the output interface 270 is connected to the optical fiber, 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 optical fiber is connected.

[0098] This embodiment detects the access status of the optical fiber automatically at low cost and with high sensitivity, making it convenient to obtain verification information of the optical fiber.

[0099] Based on any of the above embodiments, in one embodiment, the detection component 271 is a sensor disposed in the output interface 270 or within the first preset distance range of the output interface 270, 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 the optical fiber is being connected or has been connected, and verification information can be collected through the recording device 400. For another example, the detection component is a pressure sensor in the output port. When the optical fiber connector is connected to the output connector of the laser module 300, the pressure sensor detects a changing pressure signal and determines that the optical fiber is being connected or has been connected. Preferably, the pressure sensor can be a capacitive pressure sensor.

[0100] Based on any of the above embodiments, in one embodiment, the detection component 271 is a contact structure disposed on the output interface 270 of the laser module 300, and the circuit state of the contact structure changes after the optical fiber connector is connected.

[0101] For example, the output interface 270 of the laser module 300 is provided with a normally open contact. After the optical fiber connector 250 is connected to the output interface 270 of the laser module 300, 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 optical fiber is connected (or the output interface 270 is provided with a normally closed contact. After the optical fiber is connected, the normally closed contact on the output interface 270 is disconnected, and a change in the electrical signal is detected); for another example, the output interface 270 of the laser module 300 is provided with a plug contact. After the optical fiber connector 250 is connected to the output interface 270 of the laser module 300, the conductive pin on the optical fiber connector 250 connects the plug contact, and the circuit where the plug contact is located detects a change in the electrical signal, confirming that the optical fiber is connected.

[0102] Based on any of the above embodiments, in one embodiment, the input device 400 is an image acquisition device or a scanning device arranged at the output interface or within the second preset distance range of the output interface.

[0103] Specifically, the input device 400 can be a miniature image acquisition device or scanning device in the output interface 270, or an image acquisition device or scanning device set within the second preset distance range of the output interface 270. For example, the laser module 300 is integrated in the operating table, and the (laser) output interface 270 of the laser module 300 is set on the shell of the operating table. The input device 400 is set on the shell and is within a preset distance from the output interface 270. Image acquisition devices such as cameras and cameras, etc., and scanning devices such as CCD scanners, laser scanners, etc. The miniature camera is set at the output interface of the laser module 300 or within the preset distance range of the output interface, and a wired or wireless communication connection can be used to conveniently collect verification information on the solid treatment optical fiber 200 during the process of accessing the optical fiber.

[0104] This embodiment uses an image acquisition device or a scanning device set within the laser module output interface or within the second preset distance range of the output interface to automatically acquire the verification information of the optical fiber without additional operation by the user, thereby improving the convenience of the optical fiber verification process. The camera occupies a small space and avoids interference with other components.

[0105] Based on any of the above embodiments, in a preferred embodiment, the system further includes: a cooling circulation component and a foot switch.

[0106] Specifically, the front end of the optical fiber needs to be implanted in the body to perform thermal ablation on the target tissue. In order to avoid local overheating of the optical fiber, the optical fiber needs to be cooled by a cooling circulation component. The cooling circulation component may include a peristaltic pump, a cooling sleeve, a connecting pipeline, and a cooling medium. The peristaltic pump is used to provide a circulating 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; the foot switch can control the output of the laser module and adjust the output laser energy. The system may also include a display module, which 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. It can also display a human-computer interaction interface for users 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. Of course, the laser ablation system may also include more components, such as an operating trolley, a magnetic resonance device, etc., which are not limited by the present invention.

[0107] The utility model also provides a laser ablation system. The magnetic resonance-guided laser ablation system described below and the therapeutic optical fiber described above can refer to each other.

[0108] The laser ablation system provided by this method uses any of the aforementioned treatment systems in the laser ablation scenario, that is, with the assistance of stereotactic technology, the laser is introduced into the target tissue through the treatment optical fiber, and the target tissue is heated by the thermal effect of the laser to make it denature and inactivate when it reaches the target temperature range. Furthermore, the laser ablation system also includes a magnetic resonance device, which is used to collect the patient's magnetic resonance image and transmit it to the host of the laser ablation system. The host processes the magnetic resonance image to generate a temperature map to provide real-time temperature monitoring for the laser ablation process, thereby improving the safety and accuracy of laser ablation.
