The present invention relates to an air pollution reduction device and, more particularly, to a surgical smoke removing device.
Air pollution (including air pollutants or polluted air) can be generated from human activities such as cooking, surgery, smoking, drilling, or welding. In particular, the use of an electrosurgical pencil in an operating room, the use of a dental drill in a dental clinic, or the use of a welding torch in welding factory can generate noticeable air pollution.
In the case of the operating room, the electrosurgical pencil is often used for cutting, coagulating, desiccating, or fulgurating tissue. The surgical smoke is often produced during the surgery process using the electrosurgical pencil. The surgical smoke contains harmful substances, such as volatile organic compounds (VOCs), particulate matter (PM), bioaerosols, etc. Researches have shown that the surgical smoke may cause headaches, allergies, or airborne diseases (see references 1 and 2 listed below). In particular, surgeons or medical personnel involved in the surgery may suffer from respiratory diseases due to inhalation of surgical smoke. Therefore, the surgical smoke produced by the electrosurgical pencil can be harmful and should not be ignored.
One type of air pollution reduction device is a face-wearing device (e.g. a face mask), which reduces the possibility of inhaling the air pollution. However, some users may feel uncomfortable for they have to wear additional objects that cover their faces. Another type of air pollution reduction device is an air cleaner (machine), which may further be divided into two types: the stand-alone type and the portable type.
The stand-alone air cleaner is a device on its own (which includes a fixed purification base and a movable suction tube to be held near the operation place) and not installed onto the electrosurgical pencil. The base cannot be moved around easily. In addition, such stand-alone air cleaner is often operated by a person who needs to hold the suction tube near the operation location. Using the stand-alone air cleaner will increase labor costs, and more people will expose to the air pollution.
As for the portable air cleaner, it can be installed on the electrosurgical pencil. The inlet of the portable air cleaner is usually designed to be close to the tip of the electrosurgical pencil in order to capture the surgical smoke. However, the portable air purifier has only one single inlet that can only capture the surgical smoke in a small area. Meanwhile, the electrosurgical pencil attached with the portable air cleaner will take up more volume, and thus is inconvenient for the medical personnel to handle.
In the case of the dental clinic, the dental drill operated during the dental treatment will emit bioaerosols or particulate matter. Many current clinics only use stand-alone suction devices to remove air pollution generated during dental procedure. However, a stand-alone suction device may obstruct the dentist's sight, and thus affect the dental treatment. In addition, the stand-alone suction device cannot provide enough protection to the medical personnel. Therefore, there is still a need to improve the air pollution removal device in the dental clinic.
In the case of the welding factory, a welding process will produce a great amount of air pollution. Researches have shown that welding workers often suffer from lung cancer and other respiratory diseases (see references 3 and 4 listed below). The welding factory commonly uses a local exhaust ventilation (LEV) to remove the air pollution. However, it may obscure the operator's field of vision and operation.
Therefore, it is desirable to provide an improved electronic apparatus to mitigate and/or obviate the aforementioned problems.
The surgical smoke removing device of the present invention can effectively reduce the air pollution concentration of the nearby pollution source and/or deliver clean air to the user's breathing zone. The user can choose to direct the airflow to the nearby pollution source and/or the breathing zone. In other embodiments, the user can also choose to suck air pollution from the emission source and/or deliver clean air to the user's breathing zone.

[Embodiment Relevant to Surgical Lighting Apparatus]
As shown in
In an operation room, clean laminar airflow will flow down from a ceiling exhaust; it can press various pollutants toward the ground, and further toward the ground exhaust. However, during the surgery process, the surgical lighting apparatus 23 often blocks the laminar flow that flows down from the ceiling, so the person under the surgical lighting apparatus 23 may not obtain sufficient protection from the ceiling laminar flow. Commonly, the person under the surgical lighting apparatus 23 is also the one closest to the pollution source, and needs more protection. In addition, the electrocautery surgery usually generates a great amount of air pollution from the electrocautery location, and needs to be removed efficiently.
The tracer 110 is configured to trace a target point or a surgical site near the tip of an electrosurgical pencil during the surgery process, by using image recognition technology. The tracer can also trace the user's face, hand, or other target parts. In other embodiments, the tracer 110 may be an infrared sensor 111 to trace a location or a hot spot when the electrosurgical pencil is being used. The tracer 110 will accordingly generate a sensed signal, and send the sensed signal to the controller 140.
Then, the controller 140 will send a control signal to the stage 130 for the stage 130 to move the outlet 128 of the air cleaner 120, such that the outlet 128 targets at the emitting gas and/or the user. The stage 130 may be an XYZ translation stage 131 or a mechanical arm 132. When the mechanical arm 132 is introduced to serve as the stage 130, the mechanical arm 132 may further be configured to automatically move the entire surgical lighting apparatus 23 to face the operation zone (e.g. the surgical site) or the zone required by the user (e.g. the surgeon), according to the sensed signal. In this way, it is not necessary to move the surgical lighting apparatus 23 manually by the user's hand (the action may take time and the user's hand may be contaminated with blood), and thus it can save time and reduce the pollution of the handle 25. Meanwhile, since the automation of the surgical lighting apparatus 23 can increase light brightness, the tracer 130 can more accurately trace the target point by using image recognition or other technologies.
The air cleaner 120 may be a suction pump, a blower, or a fan 121, and may optionally be provided with any of the aforementioned filter components 122 or their combinations. The air cleaner 120 has an inlet 127 to suck air in. The inlet 127 may suck polluted air in by itself, or alternatively, the inlet 127 may be connected to an external apparatus (e.g. a heating, ventilation, and air conditioning (HVAC) or an external air source) that can provide purified air. The air cleaner 120 also has at least one outlet 128 (

It is of course possible to trace the user's face, hand, or other target parts. Then, the tracer 110 will accordingly generate a sensed signal, and send the sensed signal to the controller 140.
Then, the controller 140 will send a control signal to the stage 130 for the stage 130 to move the outlet 128 of the air cleaner 120, such that the outlet 128 targets at residual emitting gas and/or the user. The stage 130 may be a ball-and-socket tilt stage or an XYZ translation stage.
The air cleaner 120 may be a suction pump, a blower, or a fan, and may optionally be provided with any of the aforementioned filter components or their combinations. In a scenario of an operation room, since the operation room's air inlet can provide very clean air, it is not necessary to equip any filter component into the air cleaner 120. In a suction mode, the air cleaner 120 may suck polluted air in and filter out the polluted air. In a blow mode, the air cleaner 120 may blow purified (clean) air toward the emission source, so as to dilute and/or contain the air pollution concentration at the source.
