The application principle of high-frequency electrosurgical knife, ultrasonic knife, laser treatment machine and other equipment is based on the thermal effect. When using high-frequency electrosurgical knife, ultrasonic knife, laser treatment machine and other equipment for surgery, the high temperature can be generated in a very short time, so that The rapid expansion and gasification of biological tissue produces a mechanical pressure effect, the biological tissue is cut, separated, and solidified, and at the same time, a large amount of smoke and exhaust gas are generated from the gasification of human tissue, and these smoke and exhaust gas are all distributed in the operating room. Not only affect work, but also affect the personal health of staff and patients. Especially in the operation process, due to the cutting and separation of tissues, a large amount of smoke and waste gas of gasified tissue are generated, which affects the sight of the operator and interferes with the normal operation of the operation; in addition, the smoke of gasified tissue has peculiar smell and is harmful, thus It deteriorates the operating environment and affects the health of the operator. The risk of surgery is greater for patients with infectious diseases.

Contents of the invention

In view of the current operation process, when using high-frequency electrosurgical scalpel, ultrasonic scalpel, and laser therapy machine to cut, separate, and coagulate tissues, smoke and exhaust gas are generated, and these smoke and exhaust gases are usually directly discharged into the operating room without filtering. The status of re-emissions. In order to ensure the smooth and safe operation, facilitate the operation, purify the ambient air, and reduce the chance of infection, the smoke and exhaust gas generated during the operation are collected in time during the operation, and are discharged after effective filtration. The smoke and exhaust gas generated during the operation have their own characteristics: 1. There are few generation points, usually only one; 2. The generated area is small, only at the contact point between surgical instruments and human tissues. To achieve this purpose, a surgical smoke collection filter device is designed. This type of collecting general hose is directly connected to the corresponding surgical instrument, while the operation is performed and suctioned; or one person performs the operation, and the other collects (suctions) smoke and waste gas. That is to say, when smoke and exhaust gas are generated, the guide hose is used to directly attract and collect the smoke and exhaust gas.

The surgical smoke collection and filtering device has two main functions: 1. Collect smoke and waste gas; 2. Filter the collected smoke and waste gas. The collection of smoke and exhaust gas is provided by the power equipment to complete the collection task.

Detailed ways

The operating smoke collection and filtering device consists of a box body (1), a box cover (2), a sealing ring (3), a control unit (4), a negative pressure device (5), and a solenoid valve (6); several plate filter elements ( 7) and an array of buttons (8) are formed.

Casing (1) is made into a cuboid by airtight hard plate, can select materials such as metal, engineering plastics for use, establish partition (16) in cuboid, casing (1) is divided into two spaces: negative pressure box ( 18), filter box (19). The negative pressure box (18) acts as a buffer zone, and maintains a substantially stable negative pressure value in the box; a hole—a connection port (17) is provided in the dividing plate (16). The filter box (19) is provided with an array slot (15), and there are three to four sets of permanent sets, and an exhaust hole is provided at the end of the filter box (10)—an exhaust port (14), which is discharged from the exhaust port (14) Multi-stage filtered gas; a movable box cover (2) installed above the box body (1), and a sealing ring (3) installed under the box cover (2), between the box body (1) and the box cover (2) The number of installations is arranged on the button (8), and after the lid (2) and the casing (1) are closed, a sealed space (except the exhaust port) can be formed with the button (8). The sealing ring (3) is adopted to enhance the sealing between the case cover (2) and the case body (1).

Case cover (2) can be made into a whole, also can be made into two independent parts, covers negative pressure box (18) and filter box (19) respectively. The box cover (2) of filter box (19) can adopt whole plate, also can be provided with slot therein, can directly insert plate type filter core (7) from box cover (2) to the plug in the box body (1). In the groove (15), fix and seal again. This makes it easier to replace the filter element.

There are two commonly used methods for collecting gas, 1, range hood, vacuum cleaner type; 2, negative pressure type. Because there are few generating points (generally only one) and less amount of smoke and exhaust gas in the operation, the guide tube is long and thin, and the negative pressure gas collection can be easily set and the power consumption is small, so the negative pressure collection method can be selected , using a negative pressure device.

Negative pressure device (5) can select negative pressure suction device for use, and negative pressure suction device can adopt motor or electromagnetic pump as power. Negative pressure device (5) is selected to be placed in negative pressure case (18) case or outside the casing according to the space of negative pressure case (18) and the volume of negative pressure device (5). The air inlet of the negative pressure device (5) is placed in the negative pressure box (18), and the terminal of the air outlet of the negative pressure device (5) is placed on the connection port (17) in the partition (16), and the connection is closed Mouth (17). The negative pressure device (5) has two functions. 1. Turn the negative pressure box (18) into a negative pressure area, and use the negative pressure to absorb smoke and waste gas into the negative pressure box (18); 2. The negative pressure box (18) The gas inside is sent to the filter box (19) through the gas (collected smoke, waste gas) discharged from the outlet of the negative pressure device (5), and the gas filtered by the multi-stage filter element passes through the exhaust gas in the filter box (19). Port (14) discharges to the chamber.

Due to the different types of operations, the properties of the smoke and exhaust gas produced are different, so the filtration treatment methods are also required to be different. In order to meet the needs of different operations, multi-stage filtration is adopted; in order to facilitate the replacement of the filter element, the filter element adopts plate type ( Cuboid), the core body of plate filter element (7) is made into the filter element of different functions by different materials. Filter element function: filter fine particles in the smoke, remove peculiar smell, absorb and kill bacteria, etc. Select the filter element and quantity of different functions according to operation needs, form the filter element group that adapts to operation, and plate type filter element (7) inserts in the slot (15) in the filter box (19). Several holes are set in the box plate behind the last filter plate of the filter box (19)—the exhaust port (14), and the multi-stage filtered gas is discharged from the box body to the operating room by the exhaust port (14) .

Solenoid valve (6) can be placed in negative pressure box (18) also can be placed outside casing (1), and one port of solenoid valve (6) is installed outside negative pressure box (18) and can connect hose, and the other end Placed in the negative pressure box (18).

The control unit (4) is composed of a power switch (9), a manual switch (10), a foot switch (11), an overcurrent protector (12), and a negative pressure setting controller (13).
