[0030] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0031] Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making any creative work shall fall within the scope of protection of this application.

[0032] Please refer to Figure 1. An embodiment of the present application provides a navigation and positioning laser surgery system, including a navigation and positioning module 101, a central workstation management module 102, a laser module 103, and a laser output module 104.

[0033] The navigation and positioning module 101 includes a coordinate acquisition unit, an infrared camera and a tracking and positioning device; the coordinate acquisition unit is connected to the infrared camera and the central workstation management module 102 respectively; wherein the coordinate acquisition unit is the host of the optical navigation system.

[0034] The central workstation management module 102 is used to generate a control signal according to the received parameter setting information and send it to the laser module 103; and generate a positioning instruction according to the received navigation information and send it to the coordinate acquisition unit.

[0035] The laser module 103 is used to drive the corresponding laser generating device to generate working laser according to the control signal.

[0036] The laser output module 104 is used to output working laser through a fiber optic instrument tool.

[0037] The coordinate acquisition unit is used to obtain infrared reflection information through the infrared camera after receiving the positioning instruction, and obtain the marking positioning information according to the infrared reflection information and the tracking and positioning device.

[0038] The central workstation management module 102 is further configured to obtain the skin reference plane and the surgical tool position based on the marker positioning information, and display the skin reference plane and the surgical tool position on the operation screen of the central workstation management module 102 .

[0039] The parameter setting information is input by the user into the central workstation management module 102102 via the central workstation management module 102 operation screen. Specifically, the parameter setting information includes laser wavelength, laser operating mode, energy density, pulse time, pulse interval, and pulse count. Laser operating modes include continuous, single pulse, repetitive pulse, and fractional modes to meet multimodal laser treatment modes such as high-intensity laser therapy, low-intensity laser therapy, and photodynamic therapy. Fiber optic instruments and tools include photon probes, laser fibers, and treatment handpieces. Laser fibers include sensing fibers for monitoring and medical laser fibers for treatment. Single-mode fibers, multimode fibers, and specialty fibers (ring fibers, scattering fibers) with different core diameters can also be selected.

[0040] Laser fibers are used to transmit laser light. During minimally invasive interventional procedures, the laser fiber can enter the human body through a puncture needle, an endoscope, or a laparoscope. When the tip of the laser fiber reaches the lesion, it outputs laser light for laser surgery. The treatment handpiece is an auxiliary tool for fractional laser therapy, converting the working laser output of the laser generator into a fractional pattern. The shape, size, density, and other treatment parameters of the fractional laser spot can be set through the central workstation management module 102 operation screen. Medical staff hold the treatment handpiece and perform treatment on the patient's desired area.

[0041] The above embodiment provides a navigation and positioning laser surgery system. While implementing laser surgery through the central workstation management module 102, laser module 103, and laser output module 104, the navigation and positioning module 101 realizes real-time positioning and tracking display of the patient and surgical tools during the laser surgery. The infrared camera illuminates the tracking and positioning device on the patient to obtain infrared reflection information. The coordinate acquisition unit obtains marker positioning information based on the infrared reflection information. The central workstation management module 102 calculates the marker positioning information to obtain and display the skin reference surface and surgical tool position. The above system can track and display the relative position between the surgical tool and the patient in real time, thereby timely guiding the surgical operation, realizing visual targeted treatment, reducing the risk of surgical operation, and achieving accurate, minimally invasive, safe, and controllable lesion removal, thus realizing precision medicine.

[0042] In some embodiments, the laser module 103 includes a power drive unit and a laser generating device of multiple wavelengths; the power drive unit is respectively connected to the central workstation management module 102 and each laser generating device, and is used to power each laser generating device and send a control signal to the corresponding laser generating device to generate a working laser.

[0043] Specifically, please refer to Figure 2. The laser generating device mainly includes 1940nm, 1470nm, and 635nm / 980nm dual-wavelength laser generating devices. This application uses a three-core laser. The laser generating devices can work individually or alternately and serve as backup for each other to ensure strong output of laser energy and to the greatest extent possible ensure that the operation is not interrupted in the event of a failure of a laser generating device.

[0044] The operation screen of the central workstation management module 102 will provide four wavelength lasers for the operator to choose from. The operator selects the laser of the corresponding wavelength by clicking on the screen and records the laser wavelength in the parameter setting information, so that the central workstation management module 102 generates a control signal to start the corresponding laser generating device.

[0045] After the user selects the laser of the corresponding wavelength on the operation screen of the central workstation management module 102, he enters the laser parameter setting page, and sets various treatment parameters on this page, such as setting the working mode (continuous, single pulse, repeated pulse, fractional), treatment mode (strong laser therapy, weak laser therapy (LLLT), photodynamic therapy (PDT)), light output mode (direct, circular, scattered), as well as laser power, energy, treatment time, etc. You can also choose to set the fiber optic instrument tool (laser fiber, photon probe, treatment hand tool) to confirm and calibrate the treatment parameters. You can also choose the one-key intelligent matching parameter mode to quickly and conveniently match the treatment parameters intelligently. After the settings are completed, you need to click "Ready" on the screen to enter the real treatment standby state. At this time, the laser treatment parameters have been confirmed and locked by the system. Therefore, you can choose to connect different fiber optic instrument tools and output lasers of multiple wavelengths through different fiber optic instrument tools to perform strong laser therapy, weak laser therapy (LLLT), photodynamic therapy (PDT) and other multimodal laser treatments. Laser therapy can be achieved in different light output modes by selecting fiber optic instruments. For example, while ordinary medical optical fibers can only produce direct light, special optical fibers can produce circumferential and scattered light. Selecting a 635nm wavelength laser and connecting it to a photodynamic therapy fiber allows for photodynamic therapy.

[0046] The above embodiment adopts a multi-wavelength laser technology that can emit four specific wavelengths of laser light individually or alternately. Compared with the existing laser therapy equipment that can only emit one or two wavelengths of laser light, it has a wider range of surgical indications, richer clinical treatment functions, and more comprehensive surgical operation methods, which can better meet the needs of surgical treatment of clinical diseases.

[0047] In some embodiments, the laser output module 104 includes a plurality of laser output instrument interfaces and a fiber optic instrument tool detachably connected to each laser output instrument interface.

[0048] Each laser output device interface is connected to a laser generating device of various wavelengths in a one-to-one correspondence, and is used to receive the working laser generated by the corresponding laser generating device and output the working laser through the connected optical fiber device tool.

[0049] Please refer to FIG2 . When a triple-core laser is used, three laser output device interfaces can be set up through three laser generating devices to connect to corresponding optical fiber device tools to output lasers of four specific wavelengths.

[0050] Specifically, the laser output channel can also be set through the operation screen of the central workstation management module 102, and the laser output can be selected individually or alternately through different laser output channels. If it is set to one output channel, the lasers generated by the four wavelength laser generating devices need to be coupled and then output from a single laser output device interface, which will result in a significant increase in laser loss. At the same time, due to the addition of optical elements, the optical path may change, and the four wavelengths of laser output power are different. When the laser output is of higher power, it is possible that reflected light will return to other laser generating devices and cause damage. Therefore, the present application sets corresponding laser output device interfaces for laser generating devices of different wavelengths, realizing the independent operation of a single channel, greatly reducing laser loss, and avoiding mutual damage between laser generating devices.

[0051] The above embodiment utilizes multiple laser output channel technology, allowing different laser output channels to output laser light independently or alternately. Compared to existing laser therapy devices that utilize a single laser output channel, this embodiment better meets clinicians' needs for lasers of different wavelengths during surgery, allowing them to freely select and quickly switch between lasers of different wavelengths. Furthermore, it also ensures that even if a laser output channel malfunctions, the surgical procedure can still be completed to the greatest extent possible.

[0052] In some embodiments, the central workstation management module 102 is further configured to detect whether the connection between the optical fiber instrument tool and the laser output instrument interface is correct based on the parameter setting information; and, if incorrect, generate connection abnormality information and display it on the operation screen.

[0053] Specifically, when the fiber optic instrument tool is connected to the laser output instrument interface, the central workstation management module 102 will detect the model of the fiber optic instrument tool and the laser wavelength corresponding to the connected laser output instrument interface, compare it with the parameter setting information, and prompt the operating user whether the connection is correct through information prompts on the operation screen of the central workstation management module 102, sound prompts, or green or red flashing light signals. The three laser output device interfaces correspond to 1940nm laser, 1470nm laser, and 635 / 980nm laser respectively; when different fiber optic instrument tools are correctly connected to the corresponding laser output device interfaces, the central workstation management module 102 will send a photoacoustic signal to prompt that the connection is normal, and the laser treatment operation will automatically run to the next step. On the contrary, when the fiber optic instrument tool and the laser output device interface are not connected correctly, the central workstation management module 102 will send a photoacoustic signal to prompt that the connection is abnormal, and the laser treatment operation cannot run to the next step; because the laser output device interface is a standard SMA905 interface, it is only allowed to be connected to fiber optic instrument tools with an SMA905 interface. When other instruments need to be connected and used, they need to be indirectly connected to use the laser through a multi-function connection cable with a standard SMA905 interface.

[0054] The above embodiment can realize the connection judgment of the optical fiber instrument tool, thereby realizing the automatic detection of the preoperative system, further ensuring the safety of the operation and reducing the risk of the operation.

[0055] In some embodiments, the laser output module 104 further includes a foot-operated control unit, which is respectively connected to interfaces of each laser generating device and each laser output device.

[0056] The foot control unit is used to control the on and off of the working laser to the corresponding laser output device interface.

[0057] Specifically, the foot control unit has the authority to control laser output and stop only after the system receives the preparation instruction and enters the treatment standby state. Before entering the treatment standby state, stepping on the foot pedal will not output the laser, and the selection function of the touch screen of the central workstation management module 102 will be forcibly interrupted. The purpose of this design is to prevent system errors from causing accidental light output and causing danger.

[0058] In some embodiments, the tracking and positioning device includes a puncture needle, a positioning frame with a reflective film, and a plurality of marker balls.

[0059] The coordinate acquisition unit is used to obtain the first spatial coordinates of the positioning frame, the second spatial coordinates of each marking ball and the third spatial coordinates of the puncture needle based on the infrared reflection information; and send the first spatial coordinates, the third spatial coordinates and each second spatial coordinate as marking positioning information to the central workstation management module 102.

[0060] The central workstation management module 102 is also used to obtain a navigation range based on the first spatial coordinates and display the navigation range on the operation screen; and, to calculate a skin reference plane based on each second spatial coordinate, obtain a surgical tool position based on the third spatial coordinates, and display the skin reference plane and the surgical tool position on the operation screen.

[0061] Please refer to Figure 3, in which, when receiving the positioning instruction, the coordinate acquisition unit controls the infrared camera to emit an infrared light signal, which is detected and captured by the tracking and positioning device, and then the spatial coordinate position information is established after adaptation, registration and correction. It can also be based on the principle of binocular stereo vision, that is, using the known coordinate system correspondence to determine the calibrated unknown position, to achieve the positioning of the three-dimensional space target.

[0062] Specifically, after turning on the infrared camera, the positioning frame must be registered first: place the positioning frame flat 1.5m in front of the infrared camera, and the coordinate acquisition unit will analyze the infrared reflection information reflected by the positioning frame and form the first spatial coordinate. At this time, the calibration is successful. When the positioning frame is moved, the displayed navigation range is always in the center of the operation screen of the central workstation management module 102.

[0063] Furthermore, the marker ball is placed on the patient's skin surface before treatment and serves as a reference surface during the treatment. Specifically, after calibration, multiple marker balls are placed at the position where the patient needs to be punctured. The marker balls will reflect infrared light to the coordinate acquisition unit. The coordinate acquisition unit converts the infrared reflection information into an electrical signal and performs data analysis to obtain the second spatial coordinate and calculate to generate a reference surface. Three marker balls determine three coordinates to form a reference surface, which is used as the patient's skin reference surface.

[0064] Please refer to Figure 4. The puncture needle is also provided with a marking ball, and the reflective film on the positioning frame (positioning tool) can also be replaced by a marking ball. At this time, the puncture needle with the marking ball fixed is used to perform the surgical operation. By obtaining the third space coordinates of the marking ball on the puncture needle and the known distance between the marking ball and the puncture needle head, the position of the puncture needle head, that is, the position of the surgical tool, is obtained.

[0065] After the above operations, the user can monitor the relative position of the puncture needle and the skin surface in real time.

[0066] In some embodiments, the central workstation management module 102 is further configured to generate a three-dimensional human image including the lesion based on the case data and the skin reference surface; and to display the surgical tool position and the three-dimensional human image on the operation screen of the central workstation management module 102. Specifically, through the three-dimensional image reconstruction and the acquired second spatial coordinates, a 3D human image integrating the spatial position is formed, the lesion is accurately located, a navigation path is intelligently generated, the surgical instrument is tracked in real time, and the surgical operation is promptly guided.

[0067] Furthermore, the central workstation management module 102 mainly includes an operating screen, workstation management software, 3D imaging software, navigation software, and patient management software. Through the workstation management software, online teaching and training of laser surgical operation skills, case comparison, diagnosis and treatment analysis, and case collection can be carried out; through the navigation software, the lesion tissue can be accurately located, the navigation path can be intelligently generated, the surgical instruments can be tracked in real time, and the surgical operation can be guided in a timely manner.

[0068] Through patient management software, a patient management database can be established in a timely manner during the surgical treatment of the disease, and treatment evaluation reports can be intelligently generated. Patient treatment information before, during, and after surgery can be naturally matched and called up for viewing at any time. It can also be used as big data support for artificial intelligence algorithm analysis research and intelligent comparison, and for postoperative patient tracking and management.

[0069] The central workstation management module 102 can also realize three-dimensional reconstruction of ultrasound, CT, and MRI images through 3D imaging software, conduct surgical plan evaluation, multimodal image analysis, simulated surgical training, and visual assisted treatment. It can also be equipped with VR glasses to use 3D imaging to compose the surgical position and surgical tools in 3D, thereby generating 3D surgical renderings on the VR glasses, more intuitively displaying the position of surgical tools and surgical paths, and further realizing precise treatment.

[0070] The above embodiment adopts multimodal three-dimensional imaging technology to perform three-dimensional image reconstruction. Compared with existing laser therapy equipment, it can better meet the needs of clinicians in implementing surgical plan evaluation, multimodal image analysis, and simulated surgical training before surgical treatment of diseases, and can better realize visual and precise surgical treatment.

[0071] Please refer to FIG5 . In some embodiments, the system includes an emergency button connected to the power drive unit in the laser module 103 ; the emergency button is used to control the emergency stop of each laser generating device.

[0072] Specifically, the emergency button serves as the master control of the laser. When pressed, all laser generating devices stop outputting lasers, and the operation screen of the central workstation management module 102 cannot be clicked for settings. At this time, it is necessary to rotate it in the direction indicated on the emergency button to restore it to its initial state before other operations can be performed.

[0073] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0074] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art could make various modifications and improvements without departing from the spirit of the present application, all of which fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
