Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to an integrated system for active respiratory support and aseptic isolation for head and neck surgery. Background Technology

[0002] In surgical procedures, establishing and maintaining a strictly sterile environment is crucial for preventing surgical site infections. For head and neck surgeries, such as those involving the thyroid, parotid gland, and maxillofacial region, local anesthesia is typically used to cover the patient with a flat surgical drape. This drape has a central opening to expose the surgical field, while the surrounding area covers the patient's head, face, and torso to provide sterile isolation.

[0003] However, this traditional flat surgical drape has significant and long-standing drawbacks. Firstly, physiologically, the flat drape, while soft and lightweight, directly covers the patient's head and face, creating direct physical pressure on the mouth and nose, leading to a strong feeling of mechanical suffocation and potentially interfering with normal breathing. This is especially true for elderly, obese, or patients with respiratory insufficiency, posing a risk of hypoxemia. Secondly, psychologically, being completely covered by the drape deprives the patient of their vision, placing them in a dark, enclosed environment that easily triggers or exacerbates claustrophobia, leading to tension, anxiety, and panic. This combined physiological discomfort and psychological fear significantly reduces patient tolerance, causing unconscious movements, coughing, or attempts to lift the drape during surgery. These behaviors not only contaminate the sterilized surgical area, forcing doctors to interrupt the procedure for reassurance or re-sterilization, severely disrupting the surgical rhythm, prolonging the operation, but also increase medical risks.

[0004] Currently, there is a lack of systematic solutions in clinical practice for the above problems. Common remedial measures include attempting to artificially create some space around the patient's face when draping, or adjusting the placement of traditional oxygen masks and nasal cannulas to avoid them being covered. However, these methods are all non-standardized temporary measures with inconsistent effectiveness, and often cause potential damage to the sterile barrier or tangled tubing, or even increase the complexity of the procedure, failing to fundamentally solve the problem. Summary of the Invention

[0005] The purpose of this invention is to provide an integrated active respiratory support and aseptic isolation system for head and neck surgery. Through an integrated, deployable aseptic barrier and a built-in malleable support and air supply structure, it actively constructs and maintains a pressure-free breathing space above the surgical area while continuously delivering diffused airflow. This provides continuous and stable respiratory support to the patient while ensuring aseptic isolation of the surgical field, effectively solving the technical challenges of respiratory management difficulties and mutual interference between aseptic operating spaces in head and neck surgery.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solution: an integrated active respiratory support and sterile isolation system for head and neck surgery, comprising a sterile isolation body, the front end of which is provided with a field of view opening specifically for surgeons to observe the surgical area, the lower end of the field of view opening on the patient side is provided with a medical absorbent strip capable of absorbing blood or flushing fluid that seeps out during surgery, the inner side of the field of view opening, i.e. the side facing the doctor, is provided with a light-transmitting screen to ensure a clear and transparent field of view, and a malleable metal wire skeleton is integrated and embedded on the inner side of the sterile isolation body, i.e. the side close to the patient's face.

[0007] Furthermore, the outer end of the malleable metal wire skeleton is provided with a soft and biocompatible outer covering layer, the inner end of the malleable metal wire skeleton, i.e., the interior of the skeleton, is provided with a hollow tube for delivering oxygen, the lower end of the malleable metal wire skeleton is connected to an oxygen interface for connecting an external oxygen source, the end face of the malleable metal wire skeleton is provided with a plurality of distributed gas micropores along its direction, the distributed gas micropores penetrate the material and extend to the lower surface of the sterile isolation body, i.e., facing the patient's face, the rear end of the sterile isolation body is integrally connected to a sterile neck body for covering the patient's neck and shoulder area, and the end face of the sterile neck body is provided with a surgical opening for surgical operations.

[0008] Furthermore, the malleable metal wire skeleton is specifically arranged to extend along the upper edge of the field of vision opening, i.e., the head side and the left and right side edges, forming an inverted U-shaped or arched support frame. The malleable metal wire skeleton is constructed as a deformable support body with two stable forms: a foldable storage state and a three-dimensional support state. The U-shaped or arched frame design can effectively create a stable space in front of the patient's mouth and nose, preventing the cover from collapsing. The design of the two stable forms makes the system easy to store and transport, and at the same time, it can be quickly and reliably unfolded to the predetermined shape during surgery, making it convenient to use.

[0009] Furthermore, the hollow pipe is configured to serve both structural support and gas delivery functions, and is a component of the malleable metal wire skeleton. The oxygen interface is located on the side and rear of the malleable metal wire skeleton, integrating the gas channel and the support skeleton into one, achieving a highly integrated design, simplifying the system structure, and placing the oxygen interface on the side and rear to avoid interference with the patient's front and surgical operation area, making it more convenient to connect to the oxygen source.

[0010] Furthermore, the malleable metal wire skeleton is firmly bonded to the flexible material of the sterile isolation body through thermocompression welding, and all rigid components are completely encapsulated by the external covering layer and are not directly exposed. The thermocompression welding method ensures the firmness and sealing of the connection between the skeleton and the cover, preventing detachment. The complete encapsulation of the rigid components completely eliminates the risk of hard contact or scratches with the patient's skin, improving the safety and comfort of the product.

[0011] Furthermore, the distributed gas micropores are regularly or irregularly opened along the inner length of the hollow pipe and are configured to allow the gas to be output in a uniformly diffused manner, rather than forming a concentrated airflow. The diffused gas output method can simulate a more natural breathing environment, avoid strong airflow directly impacting the patient's face and causing discomfort or dryness of the mucous membrane, and at the same time ensure that oxygen is evenly distributed in the breathing space, resulting in better oxygen supply.

[0012] Furthermore, the malleable metal wire skeleton actively creates and maintains a pressure-free breathing cavity in front of the patient's face in a three-dimensional support state. By actively forming a protected breathing cavity through rigid support, it ensures that the patient can breathe smoothly even when covered by surgical drapes, thus solving the core risk of breathing difficulties caused by drape pressure in traditional methods.

[0013] Furthermore, the oxygen interface is a standard quick interface, and its position is designed to naturally be located on the outside of the patient's shoulder after the system is deployed. The use of a standard quick interface improves compatibility with existing oxygen supply equipment in the hospital, and the connection is quick and reliable. The design of the interface being located on the outside of the shoulder keeps it away from the surgical incision area, making it easy for anesthesiologists to operate and not affecting the sterile area of ​​the surgeon.

[0014] Furthermore, the system is constructed as an integrated structure, wherein the sterile isolation body and the neck sterile body are continuously connected by an integral material to form a sterile isolation barrier extending from the head and neck surgical area. This barrier has foldable characteristics, and can be unfolded from a folded storage state to a three-dimensional use state. The integrated continuous design avoids gaps at the splicing points of components, forming a complete and reliable sterile barrier that effectively prevents contamination. The foldable characteristics make the entire system occupy little space before surgery and can be quickly unfolded during surgery to establish a large sterile area.

[0015] Furthermore, the system is made of disposable sterile material, wherein the sterile isolation body and the sterile neck body are tightly joined by a sealed edge to form a complete sterile cover. The system is configured for single use and can be discarded after use. Single use completely eliminates the risk of cross-infection, meets the highest level of sterility requirements, and the sealed edge ensures the integrity of the barrier. Single use and disposal also simplify the postoperative handling process, eliminating the need for cleaning and disinfection, improving medical efficiency and reducing hospital infection control costs.

[0016] This invention provides an integrated system for active respiratory support and aseptic isolation for head and neck surgery, which has the following beneficial effects: This system actively creates and stably maintains an uncompressed breathing cavity in front of the patient's face through a built-in, malleable wire skeleton. This design fundamentally avoids the risk of traditional sterile single-collapse structures compressing the patient's mouth and nose, ensuring that the patient's airway remains unobstructed regardless of the length of surgery, significantly improving ventilation safety and comfort under anesthesia. The skeleton extends along the edge of the surgical opening, forming an inverted U-shaped or arched support frame. Its ingenious design not only provides strong physical support but also, due to its malleable nature, can adapt to different patients' head and facial contours within a certain range, achieving personalized spatial shaping and enhancing the system's versatility. The skeleton also features two stable forms: foldable for storage and three-dimensional support. When not in use, the entire system can be folded flat, greatly saving storage and transportation space; when needed during surgery, it can be quickly unfolded into a stable three-dimensional structure, making operation extremely simple and quick, and improving the efficiency of the operating room.

[0017] The system deeply integrates aseptic isolation with respiratory support. The aseptic isolation unit features a viewing opening on its end face, facilitating surgical manipulation. A medical absorbent strip at the lower edge of the opening effectively absorbs any fluids that may leak during surgery, such as blood or irrigation fluid, preventing spillage and contamination of the surgical area or medical staff, thus maintaining a clean and clear surgical field. A translucent screen inside the viewing opening further enhances the surgeon's visibility while also providing an additional physical barrier. More importantly, the malleable metal wire skeleton integrates hollow channels, giving it both structural support and gas delivery functions. An oxygen interface located at the rear side of the skeleton connects to an external oxygen source, allowing oxygen or a mixture of medical gases to be delivered through the hollow channels. Finally, the oxygen is released evenly, diffusely, and gently into the respiratory cavity supported by the skeleton through distributed gas micropores along the length of the inner side of the channels. This air delivery method avoids the concentrated airflow impact of traditional nasal cannulas or masks, resulting in uniform gas distribution, improved patient comfort, and prevention of strong airflow interference with delicate surgical procedures. It achieves active and comfortable respiratory support without compromising the sterile barrier.

[0018] The entire system employs an integrated structural design. The sterile isolation body and the neck sterile body used to cover the neck are continuously connected by a single material, forming a complete and continuous sterile isolation barrier extending from the patient's head and face to the neck surgical area. This integrated design eliminates gaps and weak points that may exist when assembling multiple independent components, greatly enhancing the reliability of sterile protection. Simultaneously, all rigid components, i.e., the malleable metal wire skeleton, are completely encapsulated by an external covering layer and firmly bonded to the sterile isolation body via thermocompression welding. This ensures that there are no exposed hard edges inside the system, preventing accidental punctures to the patient or sterile drapes during use, and also resulting in a smooth and flat surface for ease of use.

[0019] The system is designed with clinical ease of use in mind. The oxygen interface uses a standard quick-connect design, and its position naturally falls on the outside of the patient's shoulder when the system is deployed, facilitating quick connection and operation by anesthesiologists. The tubing layout is also rational, reducing clutter on the operating table. The surgical opening on the sterile neck unit is also optimized for the needs of head and neck surgeries.

[0020] Finally, the entire system is preferably made of disposable sterile materials. The sterile isolation body and the sterile neck body are tightly connected by sealed edges, forming a complete sterile package that is ready to use immediately. This single-use design fundamentally eliminates the risk of cross-infection caused by incomplete instrument cleaning and disinfection, meeting the highest standards of hospital infection control. It can be discarded after use, eliminating complex post-processing procedures, saving disinfection costs and manpower, and ensuring that every surgery uses brand-new, fully functional, and absolutely reliable sterile products, providing a consistent guarantee for the safety and quality of every surgery.

Detailed Implementation

[0023] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses consistent with some aspects of this disclosure as detailed in the appended claims.

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0025] How to use: 1. System preparation and inspection Before use, remove the system from its sterile packaging. Inspect the sterile isolation body 1 and the sterile neck body 4 for integrity, without damage or contamination. Confirm that the system is in a folded storage state for easy unfolding later. Check that the light-transmitting face shield 13 at the viewing opening 11 is clear and that the medical absorbent strip 12 is fully attached. Confirm that the malleable wire skeleton 2 has not undergone permanent deformation and that the outer covering layer 21 is not cracked. The oxygen interface 31 should be a standard quick-connect interface, located at the lower end of the malleable wire skeleton 2, and ensure that it is clean and unobstructed.

[0026] System Deployment Transform the system from a folded storage state to a three-dimensional support state. Holding the sterile isolation body 1, gently pull or unfold it, allowing the malleable wire skeleton 2 to naturally form an inverted U-shape or arched support frame. The malleable wire skeleton 2 is constructed as a deformable support with two stable forms: a folded storage state and a three-dimensional support state. Therefore, it automatically maintains its three-dimensional shape during unfolding without the need for additional tools. Ensure that the malleable wire skeleton 2 extends along the head side and left and right edges of the viewing opening 11 to provide stable support.

[0027] System Placement and Positioning The unfolded system is then placed over the patient's head and neck area. The sterile isolation unit 1 is positioned above the patient's face, with the viewing opening 11 aligned with the surgeon's surgical field of vision, ensuring the light-transmitting screen 13 does not obstruct observation. Simultaneously, the neck sterile unit 4 extends to the patient's neck, with the surgical opening 41 aligned with the predetermined surgical incision area. The system is a single, integrated structure; the sterile isolation unit 1 and the neck sterile unit 4 are continuously connected by a single material, forming a sterile isolation barrier extending from the head and neck surgical area. During placement, the system position is adjusted so that the oxygen interface 31 is naturally positioned on the outer side of the patient's shoulder for easy subsequent connection.

[0028] Adjustment of malleable wire skeleton and formation of breathing cavity The manually shaped flexible wire skeleton 2 is fitted to the patient's facial contours. The flexible wire skeleton 2 is firmly bonded to the sterile isolation body 1 via thermocompression welding. All rigid components are completely encapsulated by the external covering layer 21, allowing for gentle bending during shaping to avoid damage from excessive force. After adjustment, the flexible wire skeleton 2 actively creates and maintains a pressure-free breathing cavity in front of the patient's face in a three-dimensional support state, ensuring unobstructed breathing. Once shaped, the system should be securely in place and not easily shift.

[0029] Oxygen connection and respiratory support activation Connect the external oxygen source tubing to oxygen interface 31. Oxygen interface 31 is a standard quick-connect interface, designed for a rear-side location; ensure a tight and secure connection. Oxygen is delivered through hollow tubing 3, which is configured to serve both structural support and gas delivery functions. Oxygen exits from distributed gas micropores 32 within the hollow tubing 3. These micropores extend along the inner length of the hollow tubing 3, allowing for uniform gas dispersion and extending to the lower surface of the sterile isolation unit 1, providing a gentle and continuous oxygen flow to the patient and ensuring active breathing. After connection, check for normal gas flow and leaks.

[0030] Aseptic isolation confirmation and fixation Use medical absorbent strip 12 to tightly adhere to the patient's skin, ensuring a seal around the surgical opening 11 to prevent liquids or contaminants from entering. The medical absorbent strip 12, located at the lower end of the surgical opening 11, absorbs sweat or exudate that may occur during surgery, maintaining a sterile environment. Simultaneously, check that the edge of the surgical opening 41 of the sterile neck body 4 adheres to the surgical area, ensuring the entire system forms a complete sterile cover. The system is made of disposable sterile material; the sterile isolation body 1 and the sterile neck body 4 are tightly joined by sealed edges, together forming a complete sterile isolation barrier. Non-sterile contact should be avoided during use.

[0031] Use and maintenance during surgery During the surgery, the surgeon can clearly observe the surgical area through the viewing opening 11 and the light-transmitting screen 13. The light-transmitting screen 13 provides a good field of vision without affecting the operation. Simultaneously, head and neck surgical procedures can be performed through the surgical opening 41. The system maintains a continuous breathing chamber to ensure the patient's respiration, and the distributed gas micropores 32 evenly deliver oxygen to prevent hypoxia. If the system position needs adjustment, the malleable wire skeleton 2 can be slightly shaped, but care must be taken not to damage the sterile barrier. If the system becomes contaminated with blood or bodily fluids, the need for replacement should be assessed promptly; however, this system is designed for single use and generally does not support intraoperative replacement.

[0032] Post-processing After the surgery, disconnect oxygen interface 31. Then gently remove the system from the patient, avoiding tearing or spillage. Since the system is configured for single use, it should be discarded after use. Dispose of the entire system in the designated infectious waste container according to medical waste disposal guidelines; do not reuse or attempt to clean or disinfect it.

[0033] Example: Example 1 This embodiment describes the application of an integrated active respiratory support and aseptic isolation system for head and neck surgery in thyroid surgery. Before the surgery begins, the circulating nurse removes the system from its sterile packaging in a folded, stowed state. The system is an integrated structure, with the sterile isolation body 1 and the neck sterile body 4 continuously connected by a single material. The nurse unfolds the system, and its internal malleable wire skeleton 2 automatically transforms from a stowed state to a three-dimensional support state, forming a stable inverted U-shaped support frame. Under aseptic conditions, the doctor and scrub nurse cover the patient's head and neck with the system. Specifically, the sterile isolation body 1 is positioned directly above the patient's face, and its viewing opening 11 and light-transmitting face shield 13 provide the anesthesiologist with a clear window to observe the patient's lips and face. Medical absorbent strips 12 are tightly attached to the patient's forehead and the skin above both cheekbones to achieve an initial seal. At the same time, the neck sterile body 4 hangs naturally to cover the patient's neck, and its central surgical opening 41 accurately exposes the pre-designated thyroid surgical incision area. The malleable wire skeleton 2 creates and maintains an ample breathing cavity above the patient's nose and mouth, effectively avoiding the pressure that traditional sterile drapes might cause to the face. Subsequently, the oxygen supply line is connected to an oxygen inlet 31 located on the outer side of the patient's shoulder. Oxygen is delivered through a hollow tube 3 that also serves as a support, ultimately exiting from its inner distributed gas micropores 32 in a uniformly diffused manner, providing a continuous and gentle oxygen supply to the patient's facial area, thus ensuring active breathing. Throughout the procedure, the system provides the surgeon with a clean surgical opening 41 while ensuring the patient's respiratory safety and comfort. After use, it is disposed of as infectious medical waste.

[0034] Example 2 This embodiment demonstrates the application of an integrated active respiratory support and aseptic isolation system for head and neck surgery in parotid gland tumor resection. The surgical area is located on the side of the head, requiring the patient's head to be tilted to the unaffected side. When using the system, it is first unfolded from its folded state. The system's malleable wire skeleton 2 extends along the edge of the surgical opening 11, forming an arched support. During system placement, the position of the sterile neck body 4 is carefully adjusted so that its surgical opening 41 precisely covers the surgical area in front of the ear and under the jaw on the affected side. Due to the patient's specific position, the support frame needs to be adapted. The operator gently bends the malleable wire skeleton 2 using the outer covering layer 21, allowing its three-dimensional shape to better adapt to the patient's facial contours tilted to one side, ensuring effective space within the respiratory cavity in any position. The translucent face shield 13 at the surgical opening 11 provides an unobstructed view for the surgical team to observe the patient's complexion and monitor equipment. Medical absorbent strips 12 effectively absorb the small amount of sweat produced by the patient during sterile draping, maintaining the dryness and sterility of the opening edges. Oxygen is supplied via a standard quick-connect oxygen interface 31 and continuously output through a hollow conduit 3 from distributed gas micropores 32, providing stable oxygenation support for patients in a lateral decubitus position. The entire system, through the sterile isolation body 1 and the sterile neck body 4, forms a complete sterile barrier extending from the head to the neck. Its integrated design and malleable characteristics perfectly adapt to the special positioning requirements of parotid gland surgery, ensuring sterile operation while completely eliminating the potential risk of respiratory obstruction from facial coverings during surgery.

[0035] Example 3 This embodiment illustrates the application of an integrated active respiratory support and aseptic isolation system for head and neck surgery in submandibular gland resection. At the start of the surgery, after routine disinfection, the disposable aseptic integrated system is removed. Upon unfolding, the malleable wire skeleton 2 quickly establishes a stable three-dimensional configuration. Once the system is in place, the surgical opening 41 of its sterile neck body 4 precisely corresponds to the incision location in the submandibular region. This surgical area is close to the mandible, and patients often require mouth breathing; the respiratory cavity created by the system provides crucial protection for this. The surgeon can fine-tune the malleable wire skeleton 2 according to the patient's facial features, making it fit the bridge of the nose, cheekbones, and other areas to optimize the breathing space. After connecting oxygen, airflow is evenly diffused throughout the cavity from the distributed gas micropores 32, providing ample respiratory support for the patient. During the surgery, irrigation fluid or slight bleeding may occur; the sterile neck body 4, as part of the sterile barrier, effectively isolates the surgical area from the non-sterile area. The medical absorbent strip 12 at the viewing opening 11 further prevents any liquid from flowing back into the respiratory cavity or contaminating the field of vision along the patient's skin. All rigid components, including the malleable wire skeleton 2 and the hollow tube 3, are completely encapsulated by the external covering layer 21, ensuring the softness of the parts in contact with the patient and improving comfort and safety. This system seamlessly integrates respiratory protection and aseptic isolation functions into a simple, integrated structure, simplifying the draping process and creating an ideal operating environment for submandibular gland resection.

[0036] Example 4 This embodiment illustrates the synergistic application of an integrated active breathing support and aseptic isolation system for head and neck surgery in supporting laryngoscopic surgery. This surgery requires the use of a laryngoscope to penetrate deep into the larynx, demanding strict aseptic technique, and the patient's head is completely supported by the operating table. This system offers unique advantages in this scenario. Preoperatively, the system covers the patient's head and neck; the malleable wire skeleton 2 forms a three-dimensional breathing cavity above the patient's face, completely avoiding the need for sheets or tubing that might press on the patient's mouth and nose due to the placement of the laryngoscope and related instruments. The sterile neck body 4 covers the neck, and the surgical opening 41 can expose the Adam's apple area as needed. Oxygen is supplied through the oxygen interface 31, delivered via the hollow tube 3, and finally diffused towards the patient's mouth and nose through distributed gas micropores 32. This active breathing support design provides additional safety for the surgery. The system's sterile isolation body 1 and its translucent screen 13 provide a clear window for the anesthesiologist to continuously observe the patient's face and monitor their condition. The entire system is made of disposable sterile materials. The sterile isolation body 1 and the sterile neck body 4 are tightly connected by sealed edges, establishing a reliable sterile protective barrier for the patient's upper chest and above during laryngoscopy, a procedure prone to droplet and aerosol generation. After use, the entire system is discarded as a single-use item, eliminating the risk of cross-infection. This embodiment demonstrates the system's integrated solution capability in complex head and neck endoscopic surgeries, balancing surgical field sterility, anesthesia observation, and patient respiratory safety.

[0037] Example 5 This embodiment describes the application of an integrated active breathing support and aseptic isolation system for head and neck surgery in neck lymph node dissection. This surgical procedure involves a large area and requires high aseptic precision. The integrated design of this system provides a convenient and efficient coverage solution. In use, the unfolded system's aseptic isolation body 1 covers the face, while the aseptic neck body 4 naturally extends to cover the entire anterior neck and part of the upper chest. The surgeon can flexibly adjust the coverage area of ​​the aseptic neck body 4 according to the length and location of the surgical incision. The system's malleable wire skeleton 2 is constructed with two stable forms: a foldable storage state and a three-dimensional support state. After unfolding, it automatically maintains its shape, forming a stable "safe space" above the patient's face, ensuring that the patient's breathing is not compressed regardless of the duration of the surgery. The oxygen interface 31 is designed in a posterior position; after connecting the tubing, the tubing naturally runs along the outer side of the patient's shoulder, without interfering with the surgeons' operations on both sides. Oxygen is delivered evenly through the hollow tube 3 and ultimately from the distributed gas micropores 32 distributed on its inner side, achieving localized oxygen therapy to the face. The medical absorbent strip 12 ensures the sealing and dryness of the edges of the viewing opening 11. This system, through the combination of a malleable metal wire skeleton 2 and an integrated sterile barrier, creatively solves the inherent contradiction in traditional head and neck surgical draping between sterile coverage and unobstructed breathing, providing a standardized and highly safe auxiliary instrument for a wide range of neck surgeries. After surgery, this disposable product is completely removed and properly disposed of.

[0038] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
