Description

Technical Field

[0001] The invention belongs to the technical field of medical devices, and in particular relates to a multifunctional integrated electrode device. Background Art

[0002] In clinical neurosurgery, intracranial pressure monitoring is crucial for evaluating the progression of craniocerebral injury, brain tumors and other diseases. Traditional intracranial pressure monitoring equipment has a single function and cannot perform other treatment operations at the same time. Radiofrequency ablation, as a minimally invasive treatment method, has broad application prospects in the treatment of diseases such as brain tumors, but there is currently a lack of radiofrequency ablation electrodes that can combine intracranial pressure monitoring and temperature sensing functions, which is not conducive to precise treatment and real-time disease assessment. Electrode-belt intracranial pressure monitoring can monitor changes in intracranial pressure in real time, helping doctors to promptly detect abnormal intracranial pressure that may occur during surgery, so that they can take appropriate measures to improve the safety of surgery.

[0003] However, the above existing technologies have the following defects: 1. Intracranial pressure monitoring, temperature monitoring and radiofrequency ablation treatment usually need to be performed in steps, and different instruments need to be inserted multiple times, which increases the surgical risk and time cost; 2. Single-function electrodes cannot monitor and treat synchronously in real time, affecting the accuracy of treatment; 3. Traditional radiofrequency ablation electrodes fail to provide real-time feedback on intracranial pressure during surgery, making it difficult to monitor the increase in intracranial pressure during ablation, and thus unable to respond to abnormal changes in intracranial pressure in a timely and effective manner. Summary of the invention

[0004] In view of the above-mentioned deficiencies existing in the prior art, the present invention provides a multifunctional integrated electrode device to solve the above-mentioned existing problems.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions: A multifunctional integrated electrode device comprises an integrated electrode body and a multi-lumen catheter adhered to the integrated electrode body, the multi-lumen catheter is respectively provided with a hub and an integrated plug electrically connected to the hub, the integrated electrode body comprises an intracranial pressure monitoring module, a temperature sensing module and a radiofrequency ablation module which are arranged in sequence, the intracranial pressure monitoring module is provided with a slotted platinum-iridium head and a pressure sensor, and the temperature sensing module is provided with a plurality of temperature sensors.

[0006] Furthermore, the pressure sensor is electrically connected with a pressure sensor wire, the temperature sensor is electrically connected with a temperature sensor wire, and the radiofrequency ablation module is electrically connected with a conductive wire. The pressure sensor wire, temperature sensor wire, and conductive wire are correspondingly led out through a multi-lumen catheter and electrically connected to a hub.

[0007] Furthermore, the temperature sensors are distributed in a ring shape.

[0008] Furthermore, an insulating layer is coated on the surface of the integrated electrode body, and a radio frequency ablation target area is correspondingly provided in the radio frequency ablation module, and the radio frequency ablation target area is not subjected to insulation treatment.

[0009] Compared with the prior art, the present invention has the following beneficial effects: The present invention integrates intracranial pressure monitoring, temperature sensing and radiofrequency ablation or electrocoagulation ablation treatment functions, which can solve the problem that the equipment in the prior art has a single function and cannot meet the diagnosis and treatment needs at the same time.

[0011] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0012] Among them, the drawings are only used for illustrative explanations, and they only represent schematic diagrams rather than actual pictures, and should not be understood as limitations on this patent; in order to better illustrate the embodiments of the present invention, some parts of the drawings may be omitted, enlarged or reduced, and do not represent the size of the actual product; for those skilled in the art, it is understandable that some well-known structures and their descriptions in the drawings may be omitted.

[0013] like Figure 1-Figure 2As shown, a multifunctional integrated electrode device of the present invention comprises an integrated electrode body, a multi-lumen catheter S101 adhered to the integrated electrode body, a hub S102 and an integrated plug S103 electrically connected to the hub S102 are respectively arranged on the multi-lumen catheter S101, the integrated electrode body comprises an intracranial pressure monitoring module, a temperature sensing module and a radiofrequency ablation module arranged in sequence, the intracranial pressure monitoring module is provided with a slotted platinum-iridium head and a pressure sensor S202, the temperature sensing module is provided with a plurality of temperature sensors S203, the pressure sensor is electrically connected with a pressure sensor wire, the temperature sensor is electrically connected with a temperature sensor wire, the radiofrequency ablation module is electrically connected with a conductive wire, the pressure sensor wire, the temperature sensor wire and the conductive wire are correspondingly led out through the multi-lumen catheter and electrically connected to the hub, the temperature sensors are distributed in a ring, an insulating layer is coated on the surface of the integrated electrode body, the radiofrequency ablation module is correspondingly provided with a radiofrequency ablation target area, and the radiofrequency ablation target area is not insulated.

[0014] When using this device specifically, its working principle and production process are as follows: First, the pressure sensor S202 is precisely placed into the proximal portion of the slotted platinum-iridium head S201. Through the opening of the slotted platinum-iridium head S20 of the distal cannula, the cerebrospinal fluid is in contact with the pressure sensor S202, so that it can accurately sense or measure the intracranial pressure of the patient and output a corresponding signal. The pressure sensor S202 is connected through a signal pathway, and the signal generated by it can be transmitted to an external processing device (the specific device is not shown in the figure) through the pathway. When installing the pressure sensor S202, ensure that it is kept at a certain distance from the slotted platinum-iridium head S201 so that it is suspended in the air, and then inject dielectric gel to fix it; After the dielectric gel is solidified, install the tungsten tube and lead the pressure sensor wire out from the inside of the tungsten tube to ensure the stability and reliability of the connection; Carefully pass the temperature sensor wire of the temperature sensor S203 through the S101 conduit to ensure that it is accurately installed. Then, appropriately adjust the spacing of the electrode wire S205 so that it can be smoothly led out from one end of the conduit; Then, the front-end component made in step 3 is skillfully guided through the catheter using fine wire guiding technology, and it is ensured to be accurately installed in the designated position, and the front-end component is firmly bonded with adhesive; After installation, the internal head-end sensor wire is separated from the external electrode wire through the tungsten tube and PI tube S206 to effectively isolate electromagnetic interference and ensure the stability and reliability of product performance; Wire sequence marking: Wire sequence marking is performed immediately after the electrode wire is led out. This can ensure the correct connection of the electrode wire in the circuit and improve the accuracy and efficiency of installation; The organized wire harness is passed through the S102 hub, which can effectively suppress the temperature drift of the electrode and the front end under nuclear magnetic resonance; After the wires are gathered, the leads are connected to the S103 plug, and the sensor leads S204 and the electrode wires S205 are assembled in the module.

[0015] When in use, the electrode body is accurately inserted into the target part of the brain, and the intracranial pressure monitoring and temperature sensing functions are turned on to obtain real-time intracranial pressure and temperature data. When performing radiofrequency ablation treatment, set the parameters to start the treatment module, the radiofrequency generator works to generate radiofrequency current for ablation, the temperature sensing module monitors the temperature in real time and provides feedback, and the control circuit adjusts the power to ensure that the treatment temperature is appropriate until the treatment is completed. After surgery, continue to use the intracranial pressure monitoring module to observe changes in the condition.
