Detailed Description
The technical solutions of the present disclosure will be described clearly and completely with reference to the accompanying drawings, and it is to be understood that the described embodiments are only some embodiments of the present disclosure, but not all embodiments. All other embodiments, which can be derived by one of ordinary skill in the art from the embodiments disclosed herein without making any creative effort, shall fall within the protection scope of the present disclosure. In addition, technical features involved in different embodiments of the present disclosure described below may be combined with each other as long as they do not conflict with each other.
The endoscopic surgery is a minimally invasive surgery, and mainly utilizes a puncture outfit to puncture the abdominal cavity of a human body, and the puncture outfit provides an instrument channel for the surgery. Because the endoscopic surgery is carried out in a human closed body cavity, the generated surgical smoke needs to be discharged through a special smoke outlet so as to avoid the condition that the sight of a doctor is blocked and the surgical process is influenced. In the related art, it is common practice to discharge smoke in a body cavity into an operating room environment by means of pneumoperitoneum pressure of a patient during an operation using an air injection port on a puncture instrument.
However, with qualitative studies of surgical smoke, it was found that there are a large number of harmful substances in surgical smoke, such as components of cut tissue and harmful gases, including active viruses, active cancerous cells, inactive particles, pathogens, and harmful chemical components (e.g., cycloparaffins, acrylonitrile, and hydrogen cyanide). Especially for the laparoscopic surgery, the smoke discharge is relatively concentrated, and the local smoke concentration is higher, so that the health of medical staff is more damaged by smoke.
In order to solve the problem that smoke harms human bodies, a smoke filtering device is arranged in the related technology to filter operation smoke and then discharge the operation smoke, but the smoke filtering device is complex in structure, large in size and quite inconvenient to operate, and a doctor and a nurse are often required to operate independently, so that operation cost is increased greatly undoubtedly, and operation efficiency is reduced.
In view of the above-mentioned drawbacks in the related art, the inventor of the present invention has found that, because the smoke exhaust port is connected to the filtering device, the flow rate of the smoke exhaust gas is blocked, and it is difficult to exhaust smoke by means of pneumoperitoneum pressure, the smoke exhaust device in the related art is often connected to a negative pressure air pump, so as to rapidly suck and exhaust smoke. Thus, although the smoke is discharged and filtered, the structure of the filtering device is complex, an external power supply is needed to realize normal work, and special medical personnel are additionally equipped to control the operation, so that the filtering smoke exhaust device in the related technology has large volume and is complex to use, thereby improving the operation cost and reducing the operation efficiency.
Based on the above-mentioned drawbacks, the embodiments of the present disclosure provide a smoke evacuation device, which is applied to a puncture device, for example, connected to a smoke exhaust port of the puncture device, so as to filter and discharge the exhausted smoke.
In some embodiments, the smoke evacuation device of the present disclosure includes a housing and a filter assembly, the housing is a housing structure of the device, an inner cavity of the housing forms a gas flow channel for gas to flow through, and an inlet and an outlet of the gas flow channel are an air inlet end and an air outlet end which are arranged on two opposite sides of the housing.
The air inlet end is provided with a first connecting part, so that the shell can be arranged on the puncture outfit through the first connecting part. In one example, the first connecting portion may be a screw structure, and a corresponding screw structure is provided on the smoke exhaust port of the puncture instrument, so that the housing can be fixedly assembled with the puncture instrument through the screw structure. Of course, those skilled in the art will appreciate that the first connecting portion may also be any other connecting structure, such as a snap, etc., and the disclosure is not limited thereto.
The filter assembly is disposed in the airflow path of the housing interior to filter the smoke passing therethrough. In the direction from the air inlet end to the air outlet end, the filter assembly sequentially comprises a water mist filter layer, an adsorption filter layer and a gas filter layer which are arranged in a laminated mode. In embodiments of the present disclosure, the filter assembly has a gas flow loss of less than twenty percent. The gas flow loss is the difference between the gas flow rates of the filter module and the filter module not provided in the same gas flow channel, and the smaller the gas flow loss is, the smaller the influence on the exhaust gas is.
Can know through the aforesaid, this smoke exhaust apparatus of this disclosed embodiment utilizes filter assembly to filter operation smog, effectively avoids smog to cause harm to medical personnel health. And the gas flow loss of the filter assembly is less than twenty percent, on the basis of filtering harmful gas, the operation requirement is preferentially ensured, so that smoke is rapidly discharged out of a body cavity, meanwhile, as the ventilation performance of the filter assembly preferentially meets the operation smoke exhaust requirement, smoke exhaust can be realized by utilizing pneumoperitoneum pressure during operation, a negative pressure pump is not required to be added for smoke exhaust, the structure of the smoke exhaust device is greatly simplified, and the smoke can be filtered in a smaller volume.
Fig. 1 to 4 show an embodiment of the smoke evacuation device of the present disclosure, and the smoke evacuation device will be described in detail with reference to fig. 1 to 4.
In this embodiment, the smoke evacuation device includes a housing 100, and the housing 100 includes a

The water mist filter layer 210 is used for primarily filtering the mist, and mainly filters the water mist. In one example, the material of the water mist filter layer 210 may be selected from, for example, non-woven fabric, water-absorbing sponge, and the like, and may also be selected from, for example, medical foaming material made of Polyurethane (PU), polyvinyl alcohol (PVA), or other medical polymer material, which is not limited by the disclosure.
The adsorption filtration layer 220 serves to adsorb harmful components in the smoke. In one example, the material of the adsorption filtration layer 220 may be selected from an activated carbon particle layer, or may be selected from a carbon film (an activated carbon and non-woven fabric composite layer), which is not limited by the present disclosure.
The gas filter layer 230 is used for fine filtering of the smoke and filtering of fine particles. In one example, the gas filtration layer 230 may employ a micro-porous filtration membrane. It is worth noting that the pore size of the microfiltration membrane directly affects the gas permeability, i.e. the higher the accuracy the better the filtration membrane has for harmful particles, but the poorer the gas permeability. For minimally invasive surgery, it is of higher priority to ensure the normal operational requirements of the surgery.
Therefore, through a large number of experimental comparison studies, in the present embodiment, by changing the pore size of the gas filtration layer 230, it is preferable that the gas filtration layer 230 has a gas flow loss of less than twenty percent for gas filtration, i.e., the gas flow loss cannot exceed twenty percent before and after the gas filtration layer 230 is disposed. Therefore, under the condition that the requirement of smoke exhaust in the operation is not influenced, the smoke exhaust in the operation can be effectively filtered and exhausted, and the health of medical care personnel is prevented from being harmed.

Of course, those skilled in the art will appreciate that the connection manner of the housing 100 and the smoke exhaust tube 300 is not limited to the luer fitting, and any other connection manner suitable for implementation may be adopted, such as bonding, clipping, etc., and the disclosure is not limited thereto.
The other end of the smoke exhaust pipe 300 is provided with an adapter 400, and the adapter 400 is used for being connected with a puncture outfit. As shown in fig. 4, in the present embodiment, one end of the adapter 400 is a luer 410, so that the adapter 400 is fixedly connected to the smoke exhaust tube 300 through the luer 410. And the other end of the adapter 400 is a thread structure 420, so that the adapter is fixedly connected with the smoke outlet of the puncture outfit through the thread structure 420. Similarly, it is understood that the connection manner of the adapter 400, the smoke exhaust tube 300 and the puncture outfit is not limited to the example of the present embodiment, and any other connection manner suitable for implementation may be adopted, and the present disclosure does not limit this.
With continued reference to fig. 4, in the present embodiment, a check valve 500 is further provided in the flow passage of the adapter 400, and the check valve 500 is a one-way check valve through which gas can flow only in a single direction. Specifically, the check valve 500 allows the gas to flow toward the
As shown in fig. 3, when the smoke exhaust device of the present embodiment is assembled, the adapter 400 is connected to one end of the smoke exhaust pipe 300, the other end of the smoke exhaust pipe 300 is connected to the housing 100, and then the adapter 400 is mounted on the smoke exhaust port of the puncture outfit, thereby completing the assembly. Thus, by using the pneumoperitoneum pressure of the patient, the smoke discharged from the smoke outlet of the puncture outfit passes through the check valve 500 of the adapter 400, the smoke discharge pipe and the
As can be seen from the above, in the present embodiment, the smoke exhaust tube 300 guides the surgical smoke to the far end for filtering and discharging, so as to further reduce the harm of the smoke to the medical staff, and the check valve 500 effectively prevents the backflow of the external air and smoke, thereby reducing the risk of the surgical patient. It can be seen that the fume extractor in this embodiment is simple in structure, and does not need to be provided with a power source, so that the fume extractor can be provided with a smaller volume, for example, the fume extractor can be used as a disposable fume extractor, the operation is more convenient, and the operation efficiency is improved.
In addition to the above embodiments, in view of further reducing the volume and operational complexity of the smoke evacuation device, in some alternative embodiments, the housing 100 may be directly connected to the puncture instrument.
