Description

Technical Field

[0001] The invention belongs to the technical field of medical equipment, and in particular relates to a smoke exhaust device suitable for laparoscopic energy instruments. Background Art

[0002] Energy instruments used in laparoscopic surgery (such as electrocoagulation, laser, ultrasonic scalpel, etc.) will produce smoke during the operation, which is usually called "surgical smoke" or "exhaust smoke". These smokes are composed of components such as tissue burning, gas heating and cell fragments, and may contain harmful substances, posing potential risks to the health of surgical personnel and patients. Therefore, timely removal of these smoke is crucial to ensure the cleanliness of the surgical environment and reduce risks.

[0003] In the prior art, a patent with publication number "CN218105946U" discloses a single-hole laparoscopic smoke exhaust device, in which one end of a smoking tube is connected to a first adapter tube on a puncture sheath, and the air valve is opened. Under the action of a negative pressure suction device, the smoke in the abdominal cavity enters the negative pressure suction device from the smoking tube. Compared with the method of using a suction device for smoking, firstly, there is no need to replace the instrument, and smoking can be carried out by directly opening the air valve on the first adapter tube. The operation is simple and will not increase the operation time and wound bleeding time; secondly, the smoke will not flow into the air, thereby ensuring that the air in the operating room will not be polluted by the smoke, which solves the problem that the current method is to use a suction device to suck out the smoke in the abdominal cavity, but when using the suction device, the operating instrument needs to be replaced, thereby increasing the operation time and wound bleeding time. In addition, the smoke discharged into the room also pollutes the air to a certain extent.

[0004] However, the following problems still exist during the implementation of the above-mentioned device: when the smoke generated during the operation is extracted by the negative pressure device, the air pressure at the operation site will change, especially in open wounds or larger operation areas, which will affect the stability of the operation site and the pneumoperitoneum state. In addition, the smoke will also take away the temperature of the operation site while flowing, causing the patient's body temperature to drop rapidly, greatly reducing the safety of the operation.

[0005] To this end, we provide a smoke exhaust device suitable for laparoscopic energy instruments to solve the above-mentioned problems. Summary of the invention

Part; A preheating component is arranged on the top of the base 1, and the preheating component includes a heating box 10, a heater 11 is installed inside the heating box 10, and an ultrasonic atomizer 12 is installed inside the heating box 10, and the circulating gas is preheated by the preheating component; An adsorption component is arranged on the top of the base 1, and the adsorption component includes a delivery pipe 13, the delivery pipe 13 is connected to the air inlet of the negative pressure pump 2, and storage tanks 14 are arranged on the top and bottom of the delivery pipe 13, a support pipe 15 is penetrated on one side of the delivery pipe 13, an activated carbon filter element 16 is installed inside the support pipe 15, and the smoke is filtered by the adsorption component.

[0036] Specifically: the negative pressure pump 2 usually promotes the flow of air or gas through the movement of mechanical devices such as pistons, rotors or diaphragms. Under the action of these components, the gas enters the pump body and is drawn away, causing the air pressure inside the pump body to be lower than that of the outside, thereby achieving negative pressure. The air intake pipe 3 can be used to extract the smoke generated during the operation. The air intake hole 5 is opened on the surface of the adsorption tube 4, which can increase the adsorption range of the smoke. There are two turbofans 9, and the axis of the turbofan 9 is fixed to the drive shaft 18. The surface of the drive shaft 18 is movably connected to the inner wall of the partition 19 through a bearing. When the two groups of turbofans 9 rotate, air flow can be achieved on both sides of the partition 19, and the flow directions are kept opposite.

The movable sleeve 20 can be rotated to drive the two groups of storage tanks 14 to exchange positions to achieve the effect of group filtering. The diameters of the two groups of through holes 21 and the four groups of openings 22 are the same and remain horizontal and vertical. The interlayer net 23 is made of a metal filter net material and can store air adsorption and filtering particles 24. The surface of the sealing plug 25 is connected to the inner wall of the storage tank 14 by threads. When the air adsorption and filtering particles 24 are replaced, the storage tank 14 can be opened for easy access. The filter hole 26 is opened on the surface of the support tube 15 for air circulation. The limit seat 29 slides on the top of the base 1. The bottom of the storage tank 14 can be limited by moving the limit seat 29 to achieve a fixing effect.

[0043] The working principle of the present invention is as follows: when medical staff use energy equipment (such as electrocoagulation, laser, ultrasonic knife, etc.) during surgery and smoke is generated during the operation, they can hold the adsorption tube 4 and move the adsorption tube 4 to the surgical site, and then start the negative pressure pump 2 through the external controller. After the negative pressure pump 2 starts working, it generates negative pressure, and the smoke generated during the operation is sucked in through the delivery pipe 13, the conversion shell 6, the air intake pipe 3, the adsorption tube 4 and the air intake hole 5. When the smoke is discharged into the conversion shell 6 through the air intake pipe 3, the flowing smoke can drive the worm fan to rotate.

The rotation of the turbine fan 9 accelerates the air flow inside the conversion shell 6, and the air delivery pipe 7 and the exhaust pipe 8 are used to discharge the gas back to the surgical site again, so as to balance the negative pressure generated by the smoke extraction and reduce the impact on the patient's operation.

[0044] Before the gas circulates back to the surgical site, the normal saline in the heating box 10 is preheated by starting the heater 11, and the preheated normal saline is atomized by the ultrasonic atomizer 12 and discharged back to the surgical site along with the gas, thereby reducing the effect of hypothermia on the patient caused by air flow and playing a humidifying role at the same time.

[0045] When the flue gas is extracted, it can enter the storage tank 14 through the delivery pipe 13, and use the air adsorption filter particles 24 in the storage tank 14 to adsorb and filter the flue gas, while increasing the flow path of the flue gas to improve the adsorption effect. At the same time, when the flue gas is discharged into the support pipe 15, the activated carbon filter element 16 can be used to perform secondary filtration on the flue gas to further improve the flue gas filtration effect.
