Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and particularly relates to a smoke removal and purification device and a purification method for minimally invasive endoscopic surgery. Background Art

[0002] Minimally invasive surgery refers to a new technology that performs surgery inside the human body through endoscopes such as laparoscopes and thoracoscopes. Minimally invasive surgery pays more attention to the improvement and rehabilitation of the patient's psychology, society, physiology (pain), mental outlook, and quality of life, showing the greatest care for the patient and reducing the patient's pain to the greatest extent. Minimally invasive surgery does not require an incision. Only a few small holes or natural orifices of the human body are made on the patient. The patient has no scars, no pain, and can complete the whole process of examination, treatment, and rehabilitation in only 3 - 5 days, reducing the harm of traditional surgery to the human body and greatly reducing the inconvenience and pain caused by the disease to the patient. Minimally invasive surgery has the advantages of small trauma, light pain, and quick recovery.

[0003] During minimally invasive surgery, it is necessary to first use a pneumoperitoneum machine to input a gas medium (such as CO2 gas) into the patient's abdominal cavity and maintain a certain pressure to provide a good view and a large enough operating space for the surgeon. Then, the endoscope is inserted into the human body through a natural orifice of the human body or a small incision made during the operation. When in use, the endoscope is introduced into the organ to be examined, and the changes in the relevant parts can be directly observed. Then, an electric knife is used to excise the diseased or necrotic part. During the excision process of the electric knife, burning is likely to generate smoke or bleeding. The generation of smoke directly causes the image to become blurred, affecting the progress of the operation. At the same time, the bleeding site needs to be washed clean with water. Therefore, during the operation, it is necessary to remove the smoke, etc. from the human abdominal cavity.

[0004] The existing medical smoke exhaust device is in the form of blowing air at the endoscope lens, only blowing the smoke in front of the lens away. The smoke still remains inside the human body or in the smoke exhaust pipe installed on the pneumoperitoneum machine. The smoke exhaust of the pneumoperitoneum machine is directly discharged into the operating room without filtration, which is likely to cause secondary pollution in the operating room. At the same time, during the operation, the doctor needs to wipe the lens frequently to prevent the lens from being attached with smoke, water vapor, etc., making the lens blurred.

[0032] Step 1: The image acquisition module of the endoscope camera acquires a smoke-free image and stores it in the second storage unit. It also acquires the images continuously captured most recently in time and stores them in the first storage unit. In the second storage unit, the images in the first storage unit are subjected to downsampling processing and overexposure and noise removal processing to obtain a preprocessed image, which is then sent to the second processing unit to calculate the atmospheric luminance value corresponding to each channel pixel in the preprocessed image. Then, in the image generation unit, the preprocessed image from the second processing unit is compared with the feature data of each frame of the image stored in the second storage unit. If there is a deviation in the comparison value, it is determined that there is a smoke state, and the command of the third processing unit is executed to perform defogging processing.

[0033] Step 2: The image generation unit compares the preprocessed image from the second processing unit with the feature data of each frame of the image stored in the second storage unit. If there is smoke, the signal is simultaneously transmitted to the image control unit. The image control unit transmits the signal to the fog removal device control module of the smoke removal and indoor purification device. The fog removal device control module executes the control instruction to turn on the solenoid valve execution module and the vacuum pump execution module.

[0034] Step 3: The image generation unit compares the preprocessed image of the second processing unit with the feature data of each frame image stored in the second storage unit. When there is no smoke, the third processing unit does not perform defogging processing, and the image generation unit transmits the image to the image display module, which displays the image on the monitor.

[0035] Step 4: The carbon dioxide gas in the human abdominal cavity is connected to this device through the air inlet. The smoke and gas enter the solenoid valve, and the opening and closing of the solenoid valve are controlled by the control circuit board. Then it enters the primary filter. After the primary filter filters and deodorizes larger particulate dust such as smoke, it flows into the secondary filter. After the secondary filter filters and deodorizes fine particles, it enters the primary vacuum pump, and then passes through the exhaust port to discharge the filtered, clean, odorless carbon dioxide gas outside the device.

[0036] Step 5: After the air in the operating room is connected to this device through the left air inlet and the right air inlet, it flows into the primary air filter. The primary air filter filters and deodorizes larger particulate dust such as smoke in the air. Then it flows into the secondary air filter. After the secondary air filter filters and deodorizes fine particles, it enters the secondary vacuum pump, and then passes through the air exhaust port to discharge the filtered, clean air outside the device.

8. A purification method for a smoke removal and purification device for minimally invasive endoscopic surgery, characterized in that, Applied to the smoke removal and purification device for a minimally invasive medical endoscopic surgery described in any one of claims 1-4, it includes the following steps: S1. The image acquisition module (301) of the endoscopic camera (300) acquires a smoke-free image and stores it in the second storage unit (204), and acquires the images continuously captured most recently in time and stores them in the first storage unit (201). In the second storage unit (204), the images in the first storage unit (201) are subjected to downsampling processing and overexposure and noise removal processing to obtain a preprocessed image, which is then placed in the second processing unit (203). The atmospheric brightness value corresponding to each channel pixel in the preprocessed image is calculated. Then, in the image generation unit (205), the preprocessed image in the second processing unit (203) is compared with the feature data of each frame of the image stored in the second storage unit (204). If there is a deviation in the comparison value, it is determined that there is a smoke state, and the command of the third processing unit (207) is executed to perform defogging processing. Then, the image signal after defogging processing is transmitted to the image display module (208), and the image display module (208) displays the image on the display (400). S2. The image generation unit (205) compares the preprocessed image in the second processing unit (203) with the feature data of each frame of the image stored in the second storage unit (204). If there is smoke, the signal is simultaneously transmitted to the image control unit (206). The image control unit (206) transmits the signal to the demisting device control module (1001) of the smoke removal and purification and indoor purification device. The demisting device control module (1001) executes the control instruction to turn on the solenoid valve execution module (1002) and the vacuum pump execution module (1003). The smoke removal and purification and indoor purification device sucks out the smoke in the human abdominal cavity for filtration and deodorization to achieve the purpose of secondary demisting. S3. The image generation unit (205) compares the preprocessed image in the second processing unit (203) with the feature data of each frame of the image stored in the second storage unit (204). When there is no smoke, the third processing unit (207) does not perform defogging processing. The image generation unit (205) transmits the image to the image display module (208), and the image display module (208) displays the image on the display (400). S4. The carbon dioxide gas in the human abdominal cavity is connected to this device through the air inlet (106). The smoke and gas enter the solenoid valve (112), and the closing and opening of the solenoid valve (112) are controlled by the control circuit board (105). Then it enters the primary filter (114). After the primary filter (114) filters and deodorizes larger particulate dust such as smoke, it flows into the secondary filter 116. After the secondary filter 116 filters and deodorizes fine particles, it enters the primary vacuum pump (118), and then passes through the exhaust port (120) to discharge the filtered, clean, odorless carbon dioxide gas outside the device; S5. After the air in the operating room is connected to this device through the left air inlet (141) and the right air inlet (142), it flows into the primary air filter (147). The primary air filter (147) filters and deodorizes larger particulate dust such as smoke in the air, and then flows into the secondary air filter (149). After the secondary air filter (149) filters and deodorizes fine particles, it enters the secondary vacuum pump (151), and then passes through the air exhaust port (153) to discharge the filtered, clean air outside the device.
