Description

Technical Field

[0001] This invention relates to the field of surgical medical device technology, and in particular to an oral and maxillofacial surgery aid that helps patients relax. Background Technology

[0002] Oral and maxillofacial surgery is a procedure performed on the patient's jaw and mouth. Traditionally, when surgeons or surgical robots perform oral and maxillofacial surgery, the patient usually lies supine on a surgical table. While this method allows surgeons or surgical robots to easily manipulate the jaw and mouth, it has been shown in practice that patients experience significant tension (fear), which may affect the success of the surgery. Furthermore, when patients lie supine on a surgical table, they may accidentally swallow objects (especially during transoral approaches to the jawbone or alveolar bone).

[0003] Based on this, Chinese utility model patent CN203777254U discloses a novel prone head and face protection frame, including a head support frame, a support sponge, a bottom mirror, and a retractable support column. The head support frame is a mask type, with openings on it that correspond to the facial features. The support sponge is placed on the head support frame, and the support sponge also has openings that correspond to the facial features. The openings on the support sponge are adapted to the openings on the head support frame. The bottom mirror is located below the head support frame, and the head support frame and the bottom mirror are connected by a retractable support column. This design can prevent the patient's face from being squeezed, misaligned, or displaced during surgery, and the bottom mirror allows observation of the patient's face and airway patency during surgery.

[0004] However, when using this method for oral and maxillofacial surgery, the patient's mouth and jaw are facing downwards due to the patient's prone position, which makes the surgical procedure inconvenient. In addition, the procedure is not easy to observe, which poses certain safety risks. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of the aforementioned background technology by providing an auxiliary device for oral and maxillofacial surgery that facilitates patient relaxation and is convenient and safe to operate.

[0006] To achieve the above objectives, the present invention provides an oral and maxillofacial surgery assistive device that facilitates patient relaxation, comprising a mounting body and a head positioning groove formed on the mounting body. A forehead support and a jaw support are disposed within the head positioning groove. The forehead support is fixedly connected to the head positioning groove and is used to support and position the patient's forehead. The jaw support is suspended within the head positioning groove and is used to support and position the patient's mandible. The jaw support is connected to a jaw support driving mechanism, which is used to drive the jaw support to adjust its position. The head positioning groove is tilted at a preset angle relative to a vertical plane.

[0007] Furthermore, the preset angle range is 0 to 45 degrees.

[0008] Furthermore, the jaw support driving mechanism is a jaw support push rod, the fixed end of the jaw support push rod is fixedly connected to the mounting body, and the telescopic end of the jaw support push rod is connected to the jaw support through a connecting rod.

[0009] Furthermore, it also includes a display component comprising a display and a reflector, the display being positioned directly above the head positioning slot and the reflector being positioned in front of the head positioning slot, the reflector being used to enable the patient to view the display.

[0010] Furthermore, the reflector is suspended in front of the head positioning groove by a reflector bracket. The first end of the reflector bracket is fixedly connected to the mounting body, and the second end of the reflector bracket is rotatably connected to the reflector to adjust the angle of the reflector.

[0011] Furthermore, the reflector is provided with a defogging coating; or the reflector is provided with a heating defogging module.

[0012] Furthermore, the head positioning groove is also provided with a saliva bag hanger, which is used to hang a saliva bag, with the opening of the saliva bag aligned with the patient's mouth and jaw.

[0013] The above-described solution of the present invention has the following beneficial effects:

[0014] The oral and maxillofacial surgery assistive device provided by this invention can position the patient's head without restraining the patient, preventing a feeling of constraint. Therefore, patients can relax better during surgery, reducing tension and fear. Simultaneously, the head positioning groove is tilted forward, keeping the patient in a relatively comfortable position, which is more relaxing than lying completely down and facilitates oral and maxillofacial surgery. It also allows surgeons to perform surgery in a relatively comfortable posture, eliminating the need for a bottom-up approach, reducing operational difficulty, and simultaneously improving the surgical experience for both patients and surgeons. Furthermore, the display component allows for the playback of entertainment programs for patients to watch during surgery, diverting their attention and further promoting relaxation. The newly added entertainment device also ensures a safe viewing distance for the patient through reflection, preventing contamination of the operating area, simplifying cleaning methods, and maximizing space for the robotic arm.

[0015] Other beneficial effects of the present invention will be described in detail in the following detailed description section. Attached Figure Description

[0022] To make the technical problems, solutions, and advantages of this invention clearer, a detailed description will be provided below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention. Furthermore, the technical features involved in the different embodiments of this invention described below can be combined with each other as long as they do not conflict with each other.

[0023] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0024] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a locking connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0025] like Figure 1 , Figure 2As shown, an embodiment of the present invention provides an oral and maxillofacial surgery assistive device that facilitates patient relaxation, including a mounting body 10 and a head positioning groove 20 formed on the mounting body 10. The head positioning groove 20 contains a forehead support 21 and a jaw support 22. The forehead support 21 is fixedly connected to the head positioning groove 20 and is used to support and position the patient's forehead. The jaw support 22 is suspended inside the head positioning groove 20 and is used to support and position the patient's mandible.

[0026] Therefore, the combination of the forehead support 21 and the chin support 22 ensures stable positioning of the patient's head, preventing displacement of the patient's jaw relative to the head positioning groove 20 during subsequent surgery, and ensuring adaptability to patients with different head sizes. It should be noted that in this embodiment, the head positioning groove 20 is semi-elliptical in shape, matching the shape of the human face, and is relatively large, so it does not cause a feeling of constraint when the patient's head is inserted into the head positioning groove 20. Simultaneously, the forehead support 21 is shaped to match the shape of the human forehead. The forehead support 21 is preferably fixed to the top of the head positioning groove 20, allowing the forehead to directly rest against the forehead support 21 after the patient inserts their head into the head positioning groove 20, thus completing the alignment within the head positioning groove 20. The chin support 22 is shaped to match the human chin, providing comfortable support for the patient's chin. The combination of the forehead support 21 and the chin support 22 also causes almost no feeling of constraint for the patient, allowing them to relax during surgery and reducing tension and fear.

[0027] Since different patients have different head sizes, and the forehead support 21 is already fixed, the jaw support 22 in this embodiment is adjustable to accommodate and support patients with different head sizes. Specifically, the jaw support 22 is connected to the jaw support drive mechanism via an L-shaped connecting rod 23, which is used to drive the jaw support 22 to adjust its position.

[0028] At the same time, such as Figure 3 As shown, the jaw support drive mechanism is a jaw support push rod 24, preferably in the form of an electric push rod. The fixed end of the jaw support push rod 24 is fixedly connected to the mounting body 10, and the telescopic end of the jaw support push rod 24 is connected to the jaw support 22 via a connecting rod 23 to drive the jaw support 22 to adjust its position. In the initial state, the jaw support 22 can be lowered to its lowest position by the jaw support push rod 24 so that the patient's head can be better inserted into the head positioning groove 20. When the patient's forehead is in contact with the forehead support 21, the jaw support push rod 24 drives the jaw support 22 to slowly rise until it contacts (or is about to contact) the patient's chin, at which point the jaw support push rod 24 stops, allowing the jaw support 22 to support the patient's chin and further position it.

[0029] Among them, the forehead support 21 and jaw support 22 are preferably made of relatively soft materials so that the patient's forehead is more comfortable when it fits against the forehead support 21 and the jaw fits against the jaw support 22, and the patient is more relaxed during long surgery.

[0030] As described above, this embodiment positions the patient using the forehead support 21 and chin support 22 inside the head positioning groove 20, without restricting or limiting the patient's head. No other structures restricting or limiting the patient's head are also provided inside the head positioning groove 20, which can avoid causing tension to the patient and achieve the purpose of facilitating the patient's relaxation.

[0031] In existing technologies, patients typically receive surgical treatment with their mouth and jaw facing upwards, or in a prone position with their mouth and jaw facing downwards, with the surgery performed from below through the head positioning groove 20. This presents the problems mentioned in the background section. Therefore, in this embodiment, the head positioning groove 20 is tilted forward, meaning it is tilted at a preset angle relative to the vertical plane. The tilt angle can be in the range of 0–45 degrees, allowing the patient to remain in a more comfortable position, which is more relaxing than being completely prone and facilitates the oral and maxillofacial surgery. Simultaneously, it allows the surgeon to perform the surgery in a relatively comfortable posture, eliminating the need for a bottom-up approach, reducing the difficulty of the procedure, and simultaneously improving the surgical experience for both the patient and the surgeon.

[0032] To further alleviate patients' anxiety during surgery and help them remain relaxed to facilitate the procedure, this embodiment also includes a display component. The display component plays entertainment programs for patients to watch during surgery, thus diverting their attention and achieving relaxation, thereby enhancing the patient's surgical experience. Please refer again. Figure 1 The display components include a monitor 31 and a reflector 32. It is understood that when the monitor 31 is directly positioned in front of the head positioning slot 20, although the patient can view it directly, the monitor 31 requires wiring, which may affect the oral and maxillofacial surgery. Therefore, in this embodiment, the monitor 31 is positioned directly above the head positioning slot 20, and its wiring can be arranged along both sides of the mounting body 10, without affecting the surgical operation. The reflector 32 is suspended in front of the head positioning slot 20 via a reflector bracket 33. It can be rotated to adjust its angle so that the patient can view the monitor 31 directly above through the reflector 32, achieving a relaxing and entertaining effect.

[0033] During oral and maxillofacial surgery, a large amount of water sprays in front of the patient's mouth and jaw. When the reflector 32 is placed in front, the water spray may blur the reflector 32, making it difficult to see the display 31 above. Therefore, in this embodiment, the reflector 32 is further treated with a defogging coating or a heated defogging system. By setting a defogging coating or a heated defogging module (which can be set simultaneously), the water spray on the surface of the reflector 32 is removed, ensuring the reflective viewing effect. In addition, some dirt adhering to the reflector 32 is also easy to clean, which is not possible if the display 31 is placed directly in front.

[0034] At the same time, such as Figure 4 As shown, in this embodiment, the head positioning groove 20 is also provided with saliva bag hangers 25. A pair of saliva bag hangers 25 are provided and located on both sides of the head positioning groove 20. Each saliva bag hanger 25 is rod-shaped, and the saliva bag opening has an elastic cord. When hanging, the saliva bag opening is attached to the patient's lower jaw and to both saliva bag hangers 25, passing over the upper jaw to seal the lower part of the upper jaw inside the saliva bag, facilitating the collection of droplets and other contaminants generated during surgery. The nasal cavity is located outside the saliva bag, allowing the patient to breathe normally.

[0035] In summary, the oral and maxillofacial surgery assistive device provided in this embodiment can position the patient's head without restraining the patient, preventing a feeling of constraint. Therefore, the patient can relax better during the surgery, reducing tension and fear. Simultaneously, the head positioning groove 20 is tilted forward, keeping the patient in a relatively comfortable position. Compared to lying completely down, this allows for greater relaxation and facilitates oral and maxillofacial surgery. It also allows the surgeon to perform the surgery in a relatively comfortable posture, eliminating the need for a bottom-up approach, thus reducing the difficulty of the procedure and simultaneously improving the surgical experience for both the patient and the surgeon. Furthermore, the display component allows for the playback of entertainment programs for the patient to watch during surgery, diverting their attention and further enhancing relaxation.

[0036] The above description represents the preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
