Description

Technical Field

[0001] This invention relates to the field of multifunctional electrosurgical technology, and more particularly to a multifunctional electrosurgical system integrating multispectral illumination and intelligent control. Background Technology

[0002] Electrosurgical instruments are indispensable tools in modern surgery. While current technologies include monopolar, bipolar, and combined-function electrosurgical units, several challenges remain. First, in complex or deep surgeries, surgical field illumination is often limited by the surgeon's hands or head, affecting the clarity of the surgical field. Traditional external light sources (such as shadowless lamps) struggle to provide unobstructed illumination from the instrument's working angle.

[0003] Secondly, in tumor resection surgery, accurately identifying tumor boundaries and ensuring complete removal of diseased tissue while preserving healthy tissue to the greatest extent possible are key challenges. Current technologies rely on the surgeon's visual and tactile judgment, or require large, independent fluorescence imaging equipment. The need to integrate fluorescence imaging technology with the surgical instruments themselves is increasingly urgent; based on the above situation, we propose a multifunctional electrosurgical system integrating multispectral illumination and intelligent control. Summary of the Invention

[0004] This invention proposes a multifunctional electrosurgical system integrating multispectral illumination and intelligent control to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A multifunctional electrosurgical system integrating multispectral illumination and intelligent control includes a surgical handle made of insulating material, a control circuit inside the surgical handle, and a multifunctional blade head installed at the top of the surgical handle. The multifunctional blade head includes a blade head base, which is a retractable sleeve or telescopic rod. An insulating sleeve is fixedly fitted on the outer bottom of the blade head base. The insulating sleeve is embedded and fixed at the top of the surgical handle. An illumination module is embedded and fixed on the top periphery of the blade head base. The blade head base is also provided with a gas delivery channel that communicates with an external gas supply pipeline and is used to deliver argon gas. The multi-functional blade also includes electrode A and electrode B, which are fixedly installed on the top of the blade base. Electrode A and electrode B are electrically connected to the control circuit on the surgical handle. An insulating isolator is fixed between electrode A and electrode B. The insulating isolator is provided with one or more through holes for conveying fluid. The surgical handle is also equipped with a cutting button, a coagulation button, and a bipolar mode button, all of which are electrically connected to the control circuit on the surgical handle.

[0006] Preferably, the bottom of the surgical handle is equipped with a connector that is electrically connected to its control circuit. The connector is electrically connected to a connecting cable, and the connector is electrically connected to a smart connector with contacts through the connecting cable. The smart connector has a chip with a data storage module embedded in it.

[0007] Preferably, after the smart connector is inserted into the corresponding electrosurgical host, the electrosurgical host reads the chip information of the smart connector through the contact. After each use, the electrosurgical host also writes data to the chip of the smart connector and increments the usage count by one.

[0008] Preferably, when the electrosurgical host detects that the number of times the smart connector has been used has reached or exceeded a preset limit, it refuses to activate the smart connector, thus ensuring the safety of each surgery and the optimal performance of the instruments.

[0009] Preferably, the lighting module is a multispectral light source that can integrate multiple light-emitting elements of different wavelengths. The lighting module is controlled by the control circuit on the surgical handle. When working, the lighting module can emit a light beam, and the color and brightness of the light source are adjustable. The lighting module is used to inject a fluorescent contrast agent that can specifically accumulate in tumor cells into the patient before surgery, so that it emits excitation light of a specific wavelength to irradiate the surgical area during surgery. The marked tumor tissue will emit fluorescence of different colors, thus being "lit up" on the screen or in the surgeon's eyes, achieving accurate identification of the tumor boundary and guiding the scalpel for precise resection.

[0010] Preferably, electrodes A and B are arranged side by side. In bipolar mode, a radio frequency voltage is applied between electrodes A and B to form a local current loop. An insulating isolator between electrodes A and B ensures the potential difference between the two electrodes for precise tissue coagulation and sealing. In monopolar mode, the control circuit on the surgical handpiece controls electrodes A and B to be connected to the same potential, so that electrodes A and B together act as a single monopolar electrode. Current forms a circuit through this single monopolar electrode and the negative electrode plate on the patient, which is used for large-area cutting and coagulation. In monopolar mode, the outer surface of electrode B can be coated with an anti-adhesion coating and provide structural strength for the blade.

[0011] Preferably, the argon gas output from the gas delivery channel forms argon plasma under electrode stimulation. The argon plasma can achieve non-contact surface coagulation, effectively control diffuse bleeding, and blow away surgical smoke, maintaining a clear field of vision.

[0012] Preferably, the fluid delivered through the through-hole on the insulating isolator can form plasma around the electrode in bipolar or unipolar mode, achieving low-temperature, high-efficiency cutting and coagulation. At the same time, the fluid can effectively reduce the temperature of the cutting head, reducing tissue thermal damage and adhesion.

[0013] Compared with the prior art, the blade of this invention integrates an illumination module, which can not only provide conventional illumination with adjustable brightness and color for the surgical area, but also emit a light source of a specific spectrum to excite the fluorescent contrast agent, thereby highlighting tumors and other lesions in real time during the operation and achieving precise resection under fluorescence guidance. In addition, the smart connector has a built-in chip with a data storage module for tracking and limiting the number of times the instrument can be used, ensuring surgical safety.

Detailed Implementation

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0017] Reference Figure 1 A multifunctional electrosurgical system integrating multispectral lighting and intelligent control includes a surgical handle 10 made of insulating material, a control circuit inside the surgical handle 10, and a multifunctional blade head installed at the top of the surgical handle 10. The multifunctional blade head includes a blade head base 8, which is a retractable sleeve or telescopic rod. An insulating sleeve 9 is fixedly fitted on the bottom outer side of the blade head base 8. The insulating sleeve 9 is embedded and fixed at the top of the surgical handle 10. An lighting module 7 is embedded and fixed on the top periphery of the blade head base 8. The blade head base 8 is also provided with a gas delivery channel 6 that communicates with an external gas supply pipeline and is used to deliver argon gas. The multi-functional blade also includes an electrode A1 fixedly mounted on the top of the blade base 8 and an electrode B3 fixedly mounted on the top of the blade base 8. Both electrodes A1 and B3 are electrically connected to the control circuit on the surgical handle 10. An insulating isolator 4 is fixed between electrodes A1 and B3. One or more through holes 2 for conveying fluid are provided on the insulating isolator 4. The surgical handle 10 is also equipped with a cutting button 11, a coagulation button 12 and a bipolar mode button 13. The cutting button 11, the coagulation button 12 and the bipolar mode button 13 are all electrically connected to the control circuit on the surgical handle 10. The bottom of the surgical handle 10 is equipped with a connector 14 that is electrically connected to its control circuit. A connecting cable 15 is electrically connected to the connector 14. The connector 14 is electrically connected to a smart connector 16 with contacts 17 through the connecting cable 15. The smart connector 16 has a chip with a data storage module embedded in it. After the smart connector 16 is inserted into the corresponding electrosurgical host, the electrosurgical host reads the chip information of the smart connector 16 through the contacts 17. After each use, the electrosurgical host also writes data to the chip of the smart connector 16 and increments the usage count by one. When the electrosurgical host detects that the usage count of the smart connector 16 has reached or exceeded the preset limit, it refuses to start the smart connector 16, ensuring the safety of each operation and the optimal performance of the instrument.

[0018] Specifically, the illumination module 7 is a multispectral light source that can integrate various light-emitting elements of different wavelengths. The illumination module 7 is controlled by the control circuit on the surgical handle 10. When working, the illumination module 7 can emit a light beam 5, and the color and brightness of the light source of the illumination module 7 are adjustable. The illumination module 7 is used to inject a fluorescent contrast agent that can specifically accumulate in tumor cells into the patient before surgery, so that it emits excitation light of a specific wavelength to irradiate the surgical area during surgery. The marked tumor tissue will emit fluorescence of different colors, thus being "lit up" on the screen or in the eyes of the surgeon, achieving accurate identification of the tumor boundary and guiding the scalpel to perform precise resection.

[0019] Furthermore, electrodes A1 and B3 are arranged side by side. In bipolar mode, an RF voltage is applied between electrodes A1 and B3 to form a local current loop. The insulating isolator 4 between electrodes A1 and B3 ensures the potential difference between the two electrodes for precise tissue coagulation and sealing. In unipolar mode, the control circuit on the surgical handle 10 controls electrodes A1 and B3 to be connected to the same potential, so that electrodes A1 and B3 together act as a single unipolar electrode. The current forms a circuit through this single-state unipolar electrode and the negative electrode plate on the patient, which is used for large-area cutting and coagulation. In unipolar mode, the outer surface of electrode B3 can be coated with an anti-adhesion coating and provide structural strength for the blade.

[0020] Furthermore, the argon gas output from the gas delivery channel 6 forms argon plasma under electrode stimulation. Argon plasma can achieve non-contact surface coagulation, effectively control diffuse bleeding, and blow away surgical smoke to maintain a clear field of vision. The fluid delivered through the through hole 2 on the insulating isolator 4 can form plasma around the electrode in bipolar or unipolar mode, achieving low-temperature, high-efficiency cutting and coagulation. At the same time, the fluid can effectively reduce the temperature of the cutting head and reduce tissue thermal damage and adhesion.

[0021] It should be noted that the blade head of this embodiment integrates an illumination module 7, which not only provides conventional illumination with adjustable brightness and color for the surgical area, but also emits a light source of a specific spectrum to excite the fluorescent contrast agent, thereby enabling real-time high-brightness display of lesions such as tumors during surgery and achieving precise resection under fluorescence guidance. In addition, the smart connector has a built-in chip with a data storage module for tracking and limiting the number of times the instrument can be used, ensuring surgical safety. Thus, by combining high-efficiency electrosurgical resection function with advanced tissue recognition and intelligent control functions, this invention significantly improves the accuracy, efficiency, and safety of surgery.

[0022] The implementation method of this embodiment includes the following steps: S1: The smart connector 16 is inserted into the corresponding electrosurgical host. After the smart connector 16 is inserted into the corresponding electrosurgical host, the electrosurgical host reads the chip information of the smart connector 16 through the contact 17. After each use, the electrosurgical host also writes data to the chip of the smart connector 16 and increments the usage count by one. S2: When the electrosurgical host in S1 detects that the number of times the smart connector 16 has been used has reached or exceeded the preset limit, it refuses to start the smart connector 16, ensuring the safety of each operation and the best performance of the instrument. S3: The electrosurgical host in S1 activates the control circuit on the surgical handle 10 via the smart connector 16, the connecting cable 15, and the connector 14; S4: In bipolar mode, an RF voltage is applied between electrodes A1 and B3 to form a local current loop. The insulating isolator 4 between electrodes A1 and B3 ensures the potential difference between the two electrodes for precise tissue coagulation and sealing. In unipolar mode, the control circuit on the surgical handle 10 controls electrodes A1 and B3 to be connected to the same potential, so that electrodes A1 and B3 together act as a single unipolar electrode. The current forms a circuit through this single-state unipolar electrode and the negative electrode plate on the patient, which is used for large-area cutting and coagulation. S5: Regardless of whether electrodes A1 and B3 are in bipolar or unipolar mode, the illumination module 7 can not only perform normal illumination, but also, after injecting a fluorescent contrast agent that can specifically accumulate in tumor cells into the patient before surgery, it can emit excitation light of a specific wavelength to irradiate the surgical area during surgery. The marked tumor tissue will emit fluorescence of different colors, thus being "lit up" on the screen or in the surgeon's eyes, achieving accurate identification of the tumor boundary and guiding the scalpel for precise resection.
