Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a smoke-proof surgical drape. Background Technology

[0002] In modern surgery, the use of devices such as lasers, radiofrequency ablation, and plasma electrosurgical units to cut, coagulate, or cauterize human tissue has become a common technique. These devices can perform tissue processing under precise control, but they generate a large amount of fumes during the heating or cutting process. These fumes contain water vapor, tissue fragments, cellular components, and potentially harmful substances such as viruses, bacteria, cell debris, volatile organic compounds (VOCs), and possible carcinogens.

[0003] During surgery, there is a risk of medical staff inhaling fumes. This can increase the risk of infection and cancer for both medical staff and patients, and may even damage their respiratory and immune systems. Utility Model Content

[0005] This application provides a smoke-proof surgical drape, including a drape body and a negative pressure source. The drape body has an opening and a suction channel inside the drape body. The suction channel extends to the periphery of the opening and forms a suction port. The negative pressure source is connected to the suction channel and is used to provide negative pressure to the suction port.

[0006] In one embodiment of this application, the anti-smoke surgical drape has a support component connected to the drape body, and the support component is used to support the suction channel.

[0007] In one embodiment of this application, the suction channel includes a first segment and a second segment, a suction port is formed at the end of the first segment, the second segment is connected to the end of the first segment away from the suction port, a negative pressure source is disposed between the first segment and the second segment, and a support component is located in the first segment and is used to support the first segment.

[0008] In one embodiment of this application, the support component includes an elastic support member, which is connected to the towel body and supported in the suction channel;

[0009] Alternatively, the support assembly includes a bladder and an inflatable element, with the bladder disposed within the main body of the drape and located around the suction channel, and the inflatable element connected to the bladder.

[0010] In one embodiment of this application, the towel body is provided with a redundant part, and a suction channel is formed between the redundant part and the towel body. A support component is disposed in the redundant part. The redundant part has an unfolded state and a retracted state. When the redundant part is in the retracted state, the suction channel is in a first state. When the redundant part is in the unfolded state, the support component supports the suction channel, and the suction channel is in a second state. The cross-section of the suction channel in the second state is larger than that in the first state.

[0011] In one embodiment of this application, the suction channel includes at least two sub-suction channels, which extend to different sides of the opening, and both sub-suction channels are connected to a negative pressure source.

[0012] In one embodiment of this application, at least two sub-suction channels each include a main channel and multiple branches, the multiple branches are connected to the main channel, and the multiple branches of the same sub-suction channel extend to the same side of the opening and form multiple suction ports.

[0013] In one embodiment of this application, the suction channel includes a first sub-suction channel and a second sub-suction channel. Both the first sub-suction channel and the second sub-suction channel are connected to a negative pressure source. The openings have a first side and a second side that are far apart from each other. Multiple branches of the first sub-suction channel extend to the first side of the opening to form multiple first suction ports.

[0019] The technical solution adopted in this utility model achieves the following beneficial effects: The drape body can cover the patient's body surface to conceal the bacterial area outside the surgical site, reducing the risk of bacterial infection. The drape body has an opening to expose the surgical field. The opening is adapted to correspond to the patient's surgical site, allowing medical staff to perform surgical procedures through the opening. During this process, the surgery may generate fumes; a negative pressure source can provide negative pressure to the suction port, which is located around the opening. The negative pressure source can promptly extract the fumes and discharge them through the suction channel. This design can prevent fumes from being inhaled by medical staff or patients, reducing the risk of infection and cancer, and improving surgical safety. Attached Figure Description

[0034] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0035] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0036] In the various embodiments of this application, "near end" and "far end" refer to the distance of each component from the user in the usage environment. The end closer to the user is designated as the "near end", and the end farther from the user is designated as the "far end".

[0037] Today, medical surgeries using devices such as lasers, radiofrequency ablation, and plasma electrosurgical units to cut, coagulate, or burn human tissue may produce fumes. These fumes contain water vapor, tissue fragments, cellular components, and potentially harmful substances such as viruses, bacteria, cell debris, volatile organic compounds (VOCs), and possible carcinogens.

[0038] In existing surgical environments, various smoke extraction devices (such as suction guns and filters) are used to treat fumes, but these devices are not very effective. Smoke extraction devices often fail to remove fumes promptly, leaving medical staff and patients at risk of inhalation. The efficiency and safety of existing smoke treatment equipment are low. Furthermore, existing smoke emission systems often rely on the surgeon's operation, and their effectiveness is easily affected by the surgical environment and specific application.

[0039] This application provides a smoke-proof surgical drape 1, please refer to [link / reference]. Figure 1 The anti-smoke surgical drape 1 may include a drape body 100 and a negative pressure source 200, with the drape body 100 and the negative pressure source 200 connected.

[0040] The drape body 100 is used to cover the patient's body. The drape body 100 covers the patient's body surface, concealing the bacterial area outside the surgical site and reducing the risk of bacterial infection. The drape body 100 has an opening 110 that exposes the patient's surgical site, i.e., the surgical field. The opening 110 is suitable for exposing the patient's surgical site, and its size and shape are adapted to the surgical site to allow medical personnel to perform surgical procedures through the opening 110.

[0041] Please continue reading. Figure 1 The main body 100 of the towel cover has a suction channel 120 that extends to the periphery of the opening 110, forming a suction port 130. For example, the main body 100 of the towel cover may include a first towel cover and a second towel cover. The first and second towel covers overlap each other and are joined by means of heat pressing, bonding, or sewing to form the suction channel 120 between them. A negative pressure source 200 is connected to the suction channel 120 and provides negative pressure to the suction port 130. The negative pressure drives the smoke, allowing the smoke to be drawn out by the main body 100 of the towel cover.

[0042] Existing suction and exhaust equipment is bulky, and to avoid obstructing surgery, it is often installed at a considerable distance. Even when the fumes are being suctioned, medical staff may still inhale them. In this embodiment, please continue reading... Figure 1 One end of the suction channel 120 can extend to the edge of the opening 110, forming a suction port 130. Compared to medical personnel, the suction port 130 is closer to the surgical site within the opening 110, making it easier for fumes to be drawn into the suction port 130 rather than by the medical personnel. Furthermore, the suction range of the suction port 130 can cover the entire perimeter of the opening 110, significantly reducing the risk of fume leakage.

[0043] In addition to the closer proximity of the suction port 130, resulting in better suction, the suction port 130 in this embodiment is integrated into the drape body 100. This eliminates the need for medical staff to hold or set up the suction device, reducing preoperative preparation time and allowing the anti-smoke surgical drape 1 to continue suction operations without relying on the operation of medical staff.

[0044] The negative pressure source 200 provides negative pressure. The negative pressure source 200 can be a vacuum pump or a fan, etc. This embodiment does not limit the type or number of negative pressure sources 200. The power of the negative pressure source 200 is adjustable; its specific pressure value can be changed according to its own power to adapt it to more scenarios. For example, when the surgical smoke is large, the power of the negative pressure source 200 is increased to improve its suction force. Alternatively, when the surgical smoke is small, the power of the negative pressure source 200 is reduced to avoid wasting its energy and improve its power consumption ratio.

[0045] In one embodiment, the negative pressure source 200 is connected to an external power source, which supplies power to the negative pressure source 200. In another embodiment, the negative pressure source 200 has a built-in power source, which can directly supply power to the negative pressure source 200, eliminating the need for an external power source and reducing the number of steps required to operate the anti-smoke surgical drape 1.

[0046] In another scenario, the drape body 100 may also be equipped with a sensor, which may be located adjacent to the opening 110. The sensor may be a smoke sensor or similar device, capable of detecting information such as the amount of smoke generated at the opening 110. The anti-smoke surgical drape 1 may also include a controller electrically connected to the sensor and the negative pressure source 200, capable of receiving information transmitted from the sensor. Furthermore, based on the information transmitted from the sensor, the controller can automatically adjust the power of the negative pressure source 200. For example, if the sensor detects smoke generated around the opening 110, the controller automatically turns on the negative pressure source 200, which then draws in the smoke. This setup can further reduce the workload for surgical personnel.

[0047] Understandably, please refer to Figure 2In this embodiment, the negative pressure source 200 and the drape body 100 can be an integral structure. For example, the negative pressure source 200 is built into the drape body 100. During surgery, medical staff only need to place the drape body 100 on the patient's body surface and simultaneously turn on the negative pressure source 200 to complete all operations of the anti-smoke surgical drape 1. No external components are required, reducing the number of steps needed for surgery and significantly improving the surgical effect and efficiency.

[0048] Negative pressure acting within the suction channel 120, combined with atmospheric pressure compressing the drape body 100, may cause the suction channel 120 to collapse, affecting the normal use of the anti-smoke surgical drape 1. In this embodiment, please refer to... Figure 3 The anti-smoke surgical drape 1 has a support component 300, which is connected to the drape body 100 and supports the suction channel 120. The support component 300 continuously supports the wall forming the suction channel 120, maintaining the original state of the wall. The support component 300 prevents the suction channel 120 from collapsing due to wall deformation, thus ensuring the stable operation of the anti-smoke surgical drape 1. The wall can be a portion of the drape body 100 that forms the suction channel 120.

[0049] Understandably, the support component 300 supports the suction channel 120 of the drape body 100. When medical staff unfold the drape body 100, the support component 300 acts on it, automatically eliminating wrinkles caused by folding the anti-smoke surgical drape 1. This eliminates the need for medical staff to repeatedly adjust or flatten the anti-smoke surgical drape 1, further improving its ease of use and efficiency.

[0050] In one implementation, please refer to Figure 3 as well as Figure 4 The support component 300 may include an elastic support member 310, which includes, but is not limited to, metal springs (such as stainless steel sheets) and plastic springs. The elastic support member 310 connects to the towel body 100 and is supported by the suction channel 120. For example, as... Figure 4 As shown, the elastic support 310 is bonded to the main body of the towel 100 and is disposed on the outside of the suction channel 120. Alternatively, as... Figure 5 As shown, the elastic support 310 is disposed within the suction channel 120, and the elastic support 310 can support the inner wall of the suction channel 120. The elastic support 310 can be an arched metal spring sheet, and the elastic support 310 can provide elasticity. The elasticity acts on the wall forming the suction channel 120 to maintain the original shape of the suction channel 120 (such as a semi-cylindrical shape), thereby improving the effectiveness of the anti-smoke surgical drape 1.

[0051] In addition, the elastic support 310 has the ability to deform, and can deform under the action of external force. For example, during the folding process of the anti-smoke surgical drape 1, the elastic support 310 can deform to make the anti-smoke surgical drape 1 easy to store.

[0052] In another implementation, please refer to Figure 6 The support assembly 300 may include a bladder 320 and an inflation component 330. The bladder 320 is disposed within the drape body 100 and is located around the suction channel 120. Further, as... Figure 7 As shown, the capsule 320 can be disposed on the outside of the wall forming the suction channel 120. After inflation, the capsule 320 forms an arched structure. The capsule 320 connects to the wall to maintain the structure of the suction channel 120. Or, as... Figure 8 As shown, the capsule 320 can be disposed on the inner side of the wall forming the suction channel 120. After the capsule 320 is inflated, it forms an arched structure and supports the wall.

[0053] The bladder 320 can be integrated into the main body of the towel 100. For example, when the support component 300 is in use, the bladder 320 is filled with air, and the bladder 320 can be an arched structure. When the main body of the towel 100 is not in use or when it is no longer in use, the bladder 320 is deflated, and the bladder 320 and the main body of the towel 100 are stored together, reducing the number of parts and improving storage efficiency.

[0054] More specifically, there are multiple bladders 320, such as two, three, or more. These bladders 320 are spaced apart and distributed along the axial direction of the suction channel 120 within the drape body 100. All bladders 320 are connected to the inflation component 330, reducing the amount of gas required for full inflation. This arrangement reduces the required gas volume while supporting the suction channel 120 and improving the inflation efficiency of the inflation component 330.

[0055] Please continue reading. Figure 6 The inflation component 330 connects to the capsule 320, and can inflate or deflate the capsule 320. The inflation component 330 includes, but is not limited to, an air pump, an inflation canister, etc. For example, the inflation component 330 can be an inflation canister. The inflation canister is small in size and capable of holding compressed gas. The inflation canister has a certain internal pressure, and the small-volume inflation canister can be integrated within the drape body 100. When starting work, medical personnel can open the inflation canister, and the compressed gas inside can quickly fill the capsule 320. The capsule 320 expands and supports the suction channel 120. The capsule 320 and the inflation component 330 can maintain the original shape of the suction channel 120 (e.g., semi-cylindrical), improving the effectiveness of the anti-smoke surgical drape 1.

[0056] In addition, the inflation component 330 can inject warm gas into the capsule 320. The temperature of this gas can be equal to or slightly higher than the body surface temperature, such as 38°C-40°C. The heat from the gas can be conducted to the patient, providing warmth to their body, reducing discomfort, and relieving anxiety. In other cases, the capsule 320 can also be connected to an external powered inflation device, such as the 3M™ BairHugger™ system, which can stably inject warm gas to warm the patient's body; details will not be elaborated further here.

[0057] In other cases, the capsule 320 can be filled with liquid media or foaming materials, such as purified water or saline solution, and the capsule 320 can be quickly expanded to ensure the normal use of the suction channel 120.

[0058] In another embodiment, please refer to Figure 9 The suction channel 120 may include a first segment 121 and a second segment 122. The dimensions of the first segment 121 and the second segment 122 may be the same or different, and are not limited herein. A suction port 130 is formed at the end of the first segment 121, and the second segment 122 connects to the end of the first segment 121 away from the suction port 130. A negative pressure source 200 is disposed between the first segment 121 and the second segment 122. The negative pressure source 200 provides negative pressure to the suction port 130 and the first segment 121. Gases such as smoke and air pass through the negative pressure source 200 and flow to the second segment 122. The gas passes through the second segment 122 to inflate the second segment 122 until it is discharged from the end of the second segment 122 away from the first segment 121.

[0059] Understandably, please continue reading. Figure 9 The negative pressure source 200 draws air into the first section 121, creating a negative pressure environment in the first section 121. The support component 300 is located in the first section 121 and supports it. The support component 300 can be a combination of the aforementioned elastic support 310, bladder 320, and inflatable component 330. The support component 300 supports the first section 121 and can maintain its original shape (e.g., semi-cylindrical), improving the effectiveness of the anti-smoke surgical drape 1. Further details are omitted here.

[0060] The negative pressure source 200 blows air into the second section 122, creating a positive pressure environment. The pressure within the second section 122 is greater than or equal to the external environment; therefore, the second section 122 is not compressed by atmospheric pressure, and the support component 300 is not required for it. This design reduces the need for the support component 300, lowering costs, and also reduces its size, preventing it from being too large and affecting the folding and storage of the main fabric cover 100.

[0061] In this embodiment, please refer to the previous section again. Figure 3 The towel pad body 100 is provided with a redundant portion 140, and a suction channel 120 is formed between the redundant portion 140 and the towel pad body 100. For example, the towel pad body 100 has a connecting portion 150, which is connected to both ends of the redundant portion 140, so that the suction channel 120 is formed between the connecting portion 150 and the redundant portion 140. The width of the redundant portion 140 is greater than that of the connecting portion 150, and a support assembly 300 is disposed within the redundant portion 140. For example, under the support of the support assembly 300, the redundant portion 140 is configured as an arched structure, while the connecting portion 150 can still be a planar structure, forming a cylindrical suction channel 120 between the redundant portion 140 and the connecting portion 150.

[0062] The redundant portion 140 has an extended state and a retracted state. In the retracted state, the redundant portion 140 can be partially or fully retracted, meaning the redundant portion 140 and the connecting portion 150 are partially or fully fitted together. When the redundant portion 140 is in the retracted state, the suction channel 120 is in a first state, which is closed or partially closed. When the redundant portion 140 is in the extended state, the support assembly 300 supports the suction channel 120, and the suction channel 120 is in a second state. In the second state, the suction channel 120 is fully open, and its cross-section is larger than that in the first state. During this period, the suction channel 120 can be formed by a protrusion of the redundant portion 140, and no protrusions or other structures appear on the surface of the towel body 100 away from the redundant portion 140. The main body of the drape 100 covers the patient, and the main body of the drape 100 can fit the patient better, avoiding the impact of the anti-smoke surgical drape 1 on the coverage effect due to the protrusion of the surface of the main body of the drape 100, and improving the use effect of the anti-smoke surgical drape 1.

[0063] In this embodiment, please refer to Figure 10 The suction channel 120 may include at least two sub-suction channels 123. "At least two" means two or more, such as two, three, or more. The at least two sub-suction channels 123 extend to different sides of the opening 110. "Different sides" refers to adjacent or opposite sides of the opening 110. Both at least two sub-suction channels 123 are connected to the negative pressure source 200, and can extend to different areas around the opening 110, improving the overall suction effect of the suction channel 120. Furthermore, the multiple sub-suction channels 123 are independent of each other; even if one collapses or becomes blocked, the remaining sub-suction channels 123 can still function normally, improving the fault tolerance and safety of the suction channel 120.

[0064] In one implementation, please refer to Figure 11 At least two sub-suction channels 123 may each include a main channel 124 and multiple branch channels 125. The number of branch channels 125 may be two, three, or more, and there is no limitation herein. Multiple branch channels 125 are connected to the main channel 124. Multiple branch channels 125 can refine the suction pressure of the main channel 124 and act on multiple areas of the opening 110. For example, the suction channel 120 may include a first sub-suction channel 126 and a second sub-suction channel 127, both of which are connected to the negative pressure source 200. The opening 110 has a first side 111 and a second side 112 that are far apart from each other. Multiple branches 125 of the first sub-suction channel 126 extend to the first side 111 of the opening 110, forming multiple first suction ports 131. Multiple branches 125 of the second sub-suction channel 127 extend to the second side 112 of the opening 110, forming multiple second suction ports 132. The multiple first suction ports 131 and multiple second suction ports 132 are arranged opposite to each other. This arrangement can distribute fluid more evenly, thereby improving the performance and efficiency of the system and avoiding smoke leakage due to uneven suction pressure in different areas of the opening 110. Multiple branches 125 of the same sub-suction channel 123 extend to the same side of the opening 110, forming multiple suction ports 130. Furthermore, with multiple sub-suction channels 123 arranged around the opening 110, the suction effect of the multiple suction ports 130 can cover every area of ​​the opening 110, improving the suction effect of the anti-smoke surgical drape 1.

[0065] In another case, please refer to [link / reference needed]. Figure 11 The minimum distance between two adjacent suction ports 130 can be 2cm-4cm, such as 2cm, 3cm, or 4cm. The minimum distance refers to the distance between the closest edges of two adjacent suction ports 130 on the same side of the opening 110. This distance should not be set too large or too small. If the distance is too large, fumes from two adjacent suction ports 130 may leak out through the gap between them, posing a risk of inhalation to medical personnel. If the distance is too small, the suction areas of two adjacent suction ports 130 will overlap significantly, wasting the energy of the negative pressure source 200, and the two adjacent suction ports 130 may interfere with each other, leading to a decrease in suction efficiency. An appropriate distance ensures that the suction area of ​​the suction ports 130 covers every area of ​​the opening 110, improving suction efficiency, while reducing energy waste and preventing interference or influence between adjacent suction ports 130.

[0066] In addition, please continue to refer to Figure 11The diameter of the suction port 130 can be 2cm-4cm, such as 2cm, 3cm, or 4cm, etc., and this embodiment does not impose any limitation. The diameter of the suction port 130 should not be set too large or too small. When the diameter of the suction port 130 is set too large, it may excessively obstruct the vision of medical staff and reduce the operating range of the surgery. When the diameter of the suction port 130 is set too small, the flow rate of the suction port 130 is too small, and the suction effect is poor. A suction port 130 of appropriate size can balance flow rate and surgical safety, neither excessively obstructing the vision of medical staff nor failing to ensure the suction effect of the suction port 130, thereby further improving the effectiveness and safety of the anti-smoke surgical drape 1.

[0067] In addition, please continue to refer to Figure 11 The number of suction ports 130 located on the same side of the opening 110 is 3 to 6, such as 3, 4, or 6, etc., and this embodiment is not limited. For ease of understanding, for example, the shape of the opening 110 can be configured as a rectangle with four sides, and the number of suction ports 130 on each side is 3. Further, the number of suction ports 130 on the first side 111 of the opening 110 can be 3. The number of suction ports 130 on a single side of the opening 110 should not be too many or too few. Too many suction ports 130 on the same side of the opening 110 may affect the vision of medical staff, affect the surgical operation of medical staff, and also waste the energy of the negative pressure source 200. Too few suction ports 130 on the same side of the opening 110 may make it difficult to cover every area of ​​the opening 110, thus leading to smoke leakage. An appropriate number of suction ports 130 will not excessively obstruct the vision of medical staff, while also covering all areas of the opening 110.

[0068] In this embodiment, please refer to Figure 12 The anti-smoke surgical drape 1 may also include a filter element 400, which includes, but is not limited to, a filter screen, filter core, filter membrane, activated carbon pack, or a combination thereof. This embodiment does not limit the type or quantity of the filter element 400. The filter element 400 is disposed in the suction channel 120. Furthermore, the filter element 400 and the suction channel 120 are the same in size and shape. The filter element 400 can be installed in the suction channel 120 by means of adhesion or snap-fit, and this embodiment does not limit the installation method of the filter element 400. The filter element 400 can filter smoke, removing water vapor, tissue fragments, cellular components, and potentially harmful substances from the smoke. This arrangement can prevent harmful substances in the smoke from being discharged into the external environment, protecting the external environment.

[0069] In some other cases, the filter element 400 and the negative pressure source 200 can be integrated into one unit to form a filter device. The suction channel 120 of the smoke-proof surgical drape 1 is directly connected to the filter device, which can both provide negative pressure to the suction channel 120 and filter the smoke at the same time.

[0070] The technical solution adopted by this utility model can achieve the following beneficial effects: The drape body 100 can cover the patient's body surface to cover the bacterial area outside the surgical site, reducing the risk of bacterial infection. The drape body 100 is provided with an opening 110 to expose the surgical field. The opening 110 is adapted to correspond to the patient's surgical site, and medical staff perform surgical operations at the opening 110. During this period, the surgery may generate smoke. The negative pressure source 200 can provide negative pressure to the suction port 130, which is located around the opening 110. The negative pressure source 200 can promptly suck out the smoke and discharge it through the suction channel 120. This setting can prevent the smoke from being inhaled by medical staff or patients, reduce the risk of infection and cancer, and improve surgical safety.
