Description

Technical Field

[0001] The invention relates to the technical field of medical devices, and in particular to a device for protecting a neuroendoscopic camera lens. Background Art

[0002] Neuroendoscopes have good lighting and magnification functions, and can provide a clear surgical field of view, allowing neurosurgeons to more accurately observe the internal structure of the ventricles, the location and extent of lesions, and the relationship with surrounding tissues. Neuroendoscopes are widely used in the surgical treatment of ventricular diseases, such as ventricular hemorrhage and various tumors within the ventricles. For example, in the treatment of ventricular gliomas, doctors can clearly identify the boundaries of the tumor and remove the tumor as completely as possible while avoiding damage to the surrounding normal brain tissue. When dealing with ventricular hemorrhage, neuroendoscopes can accurately locate the bleeding point and remove the hematoma, reducing the pressure of the hematoma on the brain tissue. For intraventricular tumors, neuroendoscopes can also better determine the origin of the tumor and its adhesion to the surrounding tissues, thereby improving the safety and effectiveness of the operation.

[0003] However, in the process of using neuroendoscopes to treat various ventricular diseases, the camera lens is easily contaminated by blood, tissue debris, etc., which seriously affects the clarity of the field of view. In order to maintain a clear surgical field of view, doctors often need to frequently flush the lens with saline through the flushing hole on the endoscope tube. However, the flushing fluid will instantly fill the field of view in front of the lens, causing the doctor to be unable to see the surgical area clearly for a few seconds, especially when dealing with diseased tissue close to important neurovascular structures. The loss of vision for these few seconds may significantly increase the risk of surgery. In addition, the residual saline after flushing will form droplets or water films on the surface of the lens or around the surgical area. These liquid residues will cause optical phenomena such as refraction and reflection of the image, further causing blurred or deformed field of view, affecting the accuracy and safety of the operation.

[0004] Existing neuroendoscopic equipment has deficiencies in protecting and cleaning the camera lens, making it difficult to effectively solve the above problems. For example, existing equipment lacks an automated protection mechanism and is unable to promptly clean contaminants on the surface of the camera lens, resulting in frequent obstructions to the field of view during surgery. This not only affects the continuity and efficiency of the surgery, but may also have a negative impact on the patient's surgical outcomes. Therefore, there is an urgent need for a device that can continuously protect the neuroendoscopic camera lens, reduce obstruction of the field of view, and maintain image clarity, in order to improve the effectiveness and safety of complex neurosurgical operations such as ventricular diseases.

[0033] Working principle: Taking the targeted treatment of ventricular glioma as an example, the specific application process of the device for protecting the camera lens of a neuroendoscopy provided by the present invention in surgery is as follows: 1. Preoperative preparation: Imaging examinations: First, imaging examinations such as magnetic resonance imaging (MRI) and magnetic resonance spectroscopy (MRS) are used to conduct a detailed assessment of the tumor's location, size, boundaries, and its relationship to surrounding important neural structures.

[0034] Neuronavigation system: The neuronavigation system is used to import imaging data and provide precise guidance for surgical path planning.

[0035] 2. Surgical preparation: After the patient was under general anesthesia, he was placed in a supine position with his head tilted to the left. An arc-shaped incision of approximately 3 cm was made on the right forehead (the tumor was located on the right side). A bone window was formed by drilling a hole in the skull, the dura mater was cut, and the neuroendoscope was placed into the brain.

[0036] 3. Surgical process: Endoscopic guidance: The neuroendoscope gradually penetrates deeper along the sulci and gyri until it reaches the tumor. With the help of the high-definition imaging provided by the endoscope, the doctor can clearly observe that the tumor is grayish white, soft in texture, and has a certain boundary with the surrounding brain tissue.

[0037] Tumor resection: Using ultrasonic aspirators and bipolar electrocoagulation, the tumor is removed in pieces while protecting the surrounding normal brain tissue as much as possible. For areas that are closely adhered to blood vessels and important ventricular structures, the magnification and multi-angle observation functions of the neuroendoscope are used to carefully separate and avoid damage.

[0038] Neuroelectrophysiological monitoring: During the operation, neuroelectrophysiological monitoring technologies such as somatosensory evoked potential (SEP) and motor evoked potential (MEP) are used to monitor the patient's neurological function status in real time, adjust the surgical operation in time, and ensure the safety of the operation.

[0039] 4. Camera lens protection and cleaning: Equipment operation: In the process of using the neuroendoscope to penetrate deep into the ventricular system and provide high-definition imaging, the doctor inserts the operating tube 102 into the patient's brain tumor by holding the operating terminal 101, closely observes the image on the monitor, and pays attention to avoid damaging brain tissue and blood vessels.

[0040] Automatic rotation of the protective plate: Once the neuroendoscope reaches the target area, the camera body 104 at one end of the endoscope uses its magnification function and multi-angle observation capability to conduct a comprehensive observation to determine the location, morphology, and relationship of the tumor with surrounding tissues, and to find the tumor's boundaries, blood vessel supply, and important tissue structures. In this process, by adjusting the direction and depth of the endoscope, clearer and more complete image information can be obtained.

[0041] If tumor tissue needs to be obtained for pathological examination, insert the biopsy forceps through the working channel of the endoscope. Under direct vision, accurately place the biopsy forceps on the tumor tissue, select a representative site for sampling, and be careful to avoid excessive squeezing of the tumor tissue during the operation to prevent cell rupture and tissue deformation to ensure the accuracy of the pathological diagnosis results. After sampling, slowly withdraw the biopsy forceps, properly store the tissue sample, and send it to the pathology department for examination.

[0042] Automatic rotation process: When the camera lens body 104 is used for tumor observation, the protective plate 203 in the protective cover 201 will block and protect the camera lens body 104, preventing blood or tissue debris from adhering to the surface of the camera lens body 104. When blood or tissue debris is attached to the area where the protective plate 203 is located on one side of the camera lens body 104, the small motor is started to drive the rotating rod 205 to rotate, thereby driving the protective plate 203 to rotate. After the rotation, the dirty area 203 is transferred to the protective cover 201, and the clean area 203 is rotated to the side of the camera lens body 104, maintaining the clarity of the observation side of the camera lens body 104.

[0043] Reducing interference with the field of view: Compared with the traditional method of flushing with physiological saline, the present invention achieves protection by rotating the protective plate 203, reducing the instantaneous filling of the field of view with the flushing liquid and the occurrence of image refraction and reflection, thereby improving the clarity of the field of view of the camera lens body 104 for tumor observation.

[0044] Cleaning and separation mechanism: The cleaning component and the separation component work together: During the rotation of the protective plate 203, the cleaning component 3, the separation component 4 and the first driving component 6 work together. The rubber abutting plate 302 on one side of the cleaning plate 301 abuts against the side wall of the protective plate 203 to scrape the surface dirt. The dirty blood or tissue debris is sucked out by the processing component 7. The entire cleaning process is completed in a closed area to avoid affecting other brain tissues of the patient.

[0045] Vibration shedding of the shedding component: During the rotation of the rotating rod 205, the three arc-shaped driving plates 601 are driven to rotate. When the arc-shaped driving plate 601 abuts against the driving rod 603, the interaction force of the fillet 602 and the guiding action of the telescopic component 5 push the opening plate 402 to move away from the protective plate 203, so as to avoid scraping the blood or tissue debris attached to the surface of the protective plate 203 during the rotation of the protective plate 203. As the rotating rod 205 drives the protective plate 203 to continue to rotate, when the cleaning area of ​​the protective plate 203 rotates to one side of the camera lens body 104, the driving rod 603 will be between two adjacent arc-shaped driving plates 601. Under the elastic action of the telescopic component 5, the opening plate 402 is pushed against the side wall of the protective plate 203 again, so as to isolate the use area and the non-use area of ​​the protective plate 203 and avoid cross contamination between them.

[0046] At the same time, during the rotation of the protective plate 203, the rubber abutting plate 302 on one side of the cleaning plate 301 will abut against the side wall of the protective plate 203, and then the use area of ​​the protective plate 203 is cleaned under the scraping effect of the rubber abutting plate 302 on the surface of the protective plate 203. After the blood or tissue debris in the use area of ​​the protective plate 203 is intercepted, the external vacuum pump is started, and the blood or tissue debris in the cleaning area of ​​the protective sleeve 201 is sucked out from each suction tube 703 through the suction force, so that the blood or tissue debris generated during the examination and treatment of the neuroendoscope can be promptly processed, and the entire processing process is in a closed area to avoid affecting other brain tissues of the patient.

[0047] Functions of the abutting roller and the driving ring: During the rotation of the protective plate 203, the abutting contact between the abutting roller 903 and the protective plate 203 drives the rotating shaft 902 to rotate, and then drives the multiple semicircular protrusions 905 on the side wall of the driving ring 904 to rotate. During the rotation of each semicircular protrusion 905, it will reciprocate against the side wall of the sliding plate 801. Under the interaction force between each semicircular protrusion 905 and the sliding plate 801 and the guidance of each shedding rod 802 and the U-shaped plate 803 and the reset action of the spring 804, each shedding rod 802 is pushed to reciprocate against the side wall of the cleaning plate 301, so that the side wall of the cleaning plate 301 is slightly vibrated. The slight vibration caused by the force on the side wall of the cleaning plate 301 helps to vibrate and fall off the tissue debris attached to the side wall of the cleaning plate 301 and the rubber abutting plate 302, further improving the treatment effect of the neuroendoscope on blood and tissue debris during the inspection and treatment process.

[0048] After the surgery for ventricular glioma, the patient returned to the intensive care unit (ICU) for close observation and was given treatment such as dehydration, intracranial pressure reduction, and infection prevention. A head CT scan was performed on the first day after surgery, showing that most of the tumor had been removed and there was no obvious edema or bleeding in the surrounding brain tissue. One week after surgery, the patient was conscious, and his limb weakness symptoms were significantly improved compared with those before surgery, and he gradually resumed normal activities. Postoperative pathological examination confirmed that it was a glioblastoma (GBM). According to the patient's condition and pathological results, a comprehensive treatment plan of synchronous chemoradiotherapy was formulated to further control the recurrence and metastasis of the tumor.
