[0002] With the continuous progress of medical technology, minimally invasive surgery, especially laparoscopic surgery, has been widely used in clinical practice due to its small trauma, rapid recovery and other characteristics. During the operation, a large amount of smoke is often generated due to the use of electrosurgical equipment such as electric knives, ultrasonic knives and bipolar electrocoagulation. These smoke is mainly composed of water vapor, blood and tissue fragments, which not only blocks the surgical field and increases the difficulty of the operation, but also may contain harmful particles and viruses, posing a potential threat to the health of the operating personnel and the patient. Therefore, effective discharge of surgical smoke has become a problem that needs to be solved in laparoscopic surgery.

Pressure fluctuations may cause tissue movement, thereby affecting the accurate operation of surgical instruments. In addition, excessively high intra-abdominal pressure may increase the risk of pneumoperitoneum-related complications in patients, such as subcutaneous emphysema and pneumothorax. On the other hand, excessively low pressure may affect the smooth progress of the operation. Therefore, it is necessary for the staff to improve the device. CONTENT OF THE UTILITY MODEL

DETAILED DESCRIPTION
[0023] The technical solutions in the embodiments of the utility model will be apparently and completely described in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the protection scope of the utility model.
[0024] Embodiment one:
[0025] Please refer to Figures 1 to 4 Fig. 1 shows an intelligent induction surgical smoke exhaust device, comprising:
[0026] The smoke pipe 1;
[0027] The front end of the smoke pipe 1 is fixedly connected with the threaded pipe 2, the surface of the threaded pipe 2 is threadedly connected with the mounting pipe 3, the front end of the mounting pipe 3 is installed in the trocar side hole, the inner wall of the mounting pipe 3 is provided with the connecting groove 4, and the inner wall of the connecting groove 4 is threadedly connected to the surface of the threaded pipe 2. The threaded pipe 2 is threadedly connected into the connecting groove 4 of the mounting pipe 3 at the front end of the smoke pipe 1. Thus, the smoke pipe 1 and the mounting pipe 3 are conveniently disassembled and assembled, ensuring that the mounting pipe 3 can be quickly replaced or cleaned during the operation process. The tail end of the mounting pipe 3 is fixedly connected with the sealing pipe 5, and the surface of the sealing pipe 5 is inserted into the inner wall of the smoke pipe 1. The sealing pipe 5 is made of elastic material and tightly adheres to the inner wall of the smoke pipe 1, so that the sealing effect can be maintained even when the suction force changes;
[0028] The inner wall of the installation pipe 3 is fixedly connected with a pressure sensor 6, and the inner wall of the installation pipe 3 is fixedly connected with a smoke sensor 7 on the opposite side of the pressure sensor 6. The pressure in the abdominal cavity is monitored by the pressure sensor 6, and whether smoke is generated in the abdominal cavity and the amount of smoke generated are monitored by the smoke sensor 7. The pressure of the negative pressure absorption system is automatically adjusted according to the data of the pressure sensor 6 to ensure that the pressure in the abdominal cavity is constant. At the same time, the suction force of the smoke extraction device is intelligently adjusted according to the smoke concentration monitored by the smoke sensor 7 to achieve precise smoke extraction. The inner wall of the smoke extraction pipe 1 is rotatably connected with an electromagnetic valve 17, which is adjusted by the control panel 16. The suction force in the smoke extraction pipe 1 is controlled by the electromagnetic valve 17.
[0029] According to the smoke concentration monitored by the smoke sensor 7, the control system can intelligently adjust the suction force of the smoke extraction device. When the smoke concentration increases, the system will increase the suction force of the smoke extraction device to absorb the smoke faster. Conversely, when the smoke concentration decreases, the system will reduce the suction force of the smoke extraction device to save energy.
[0030] The pressure in the abdominal cavity is maintained at a constant pressure region. When the suction force needs to be increased, the control system will open the electromagnetic valve 17 to allow more airflow into the smoke extraction pipe 1. When the suction force needs to be reduced, the control system will close part or all of the channels of the electromagnetic valve 17 to reduce the airflow into the smoke extraction pipe 1.
[0031] Through this intelligent adjustment mechanism, the smoke can be absorbed in time and effectively, and the electromagnetic valve 17 is the key component for controlling the suction force in the smoke extraction pipe 1. By adjusting the electromagnetic valve 17 through the control panel 16, the airflow in the smoke extraction pipe can be accurately controlled, thereby intelligently extracting the smoke in the abdominal cavity while ensuring the relative stability of the pressure in the abdominal cavity.

[0035] The pressure sensor 6 and the smoke sensor 7 are tested for compatibility when manufactured by the manufacturer, so that they can be sterilized by the STERRAD 100S type low temperature plasma sterilizer.
[0036] Other components except the control panel 16 can be treated with conventional high temperature steam sterilization, the connecting tube 12 can be replaced every operation, the control panel 16 can be independently detached and sterilized with 75% alcohol.

Therefore, an efficient and intelligent surgical smoke exhaust device is particularly important in laparoscopic surgery.
[0041] During the operation, turn on the power of the device and start the negative pressure suction system.
[0042] When using electrosurgical equipment for electric cutting or electrocoagulation hemostasis, the smoke sensor 7 will monitor the generation of smoke in real time and automatically adjust the suction force of the smoke extraction device to quickly exhaust the surgical smoke from the surgical field.
