Abstract
Description
Technical Field
[0001] This invention belongs to the field of postoperative medical device technology in maxillofacial surgery, specifically relating to a head-mounted temporomandibular joint postoperative compression device. Background Technology
[0002] Following temporomandibular joint surgery, patients often experience bleeding, effusion, and soft tissue swelling at the surgical site. Clinically, it is usually necessary to apply external pressure to the surgical area in the early postoperative period to promote local tissue adhesion, reduce hematoma and effusion formation, and aid in postoperative wound healing. Therefore, postoperative pressure is one of the commonly used adjunctive management measures after temporomandibular joint surgery.
[0003] Currently, the most commonly used postoperative compression methods in clinical practice include bandage wrapping and elastic headgear wrapping. Bandage wrapping typically creates a circumferential compression around the face and top of the head, with gauze added in the preauricular area to provide continuous pressure to the surgical area. Elastic headgear compression is similar to bandage wrapping, covering the entire face and chin, combined with the compression of gauze in the preauricular area to achieve fixation and pressure. While these methods can meet postoperative compression needs to some extent, they still have many shortcomings in practical application.
[0004] On the one hand, existing compression methods are prone to gauze displacement, and the pressure distribution is relatively dispersed, making it difficult to achieve localized, precise, and controllable directional pressure on the temporomandibular joint surgical area and near the incision. On the other hand, traditional bandages or head coverings are not only uncomfortable to wear, but also affect eating and speech due to the covering of the chin, and are aesthetically unappealing, easily leading to patient resistance and seriously affecting patients' daily activities during postoperative recovery and their long-term adherence to wearing them.
[0005] Therefore, there is an urgent need in the existing technology for a directional compression device suitable for use after temporomandibular joint surgery, which can reduce the impact on pronunciation, chewing and mandibular movement while ensuring effective local compression, and improve wearing comfort, aesthetics and postoperative individualized adaptation. Summary of the Invention
[0006] The purpose of this invention is to overcome the problems of existing temporomandibular joint postoperative compression methods, such as large compression range, poor local orientation, insufficient wearing comfort, impact on appearance, and interference with the patient's breathing, swallowing, and mandibular movement. The invention provides a head-mounted temporomandibular joint postoperative compression device to achieve precise local compression of the temporomandibular joint surgical area and improve the postoperative wearing comfort, aesthetics, and precise adaptation to individual anatomical structures.
[0007] To achieve the above objectives, the present invention provides a headband-type postoperative temporomandibular joint compression device, comprising a telescopic headband and two malleable joint compression components symmetrically arranged at both ends of the telescopic headband; the malleable joint compression components are hinged to both ends of the telescopic headband and are non-removable; the telescopic headband includes an outer tube and two inner tubes extending from both sides of the outer tube and overlapping each other in the central region of the outer tube, a knob is provided in the center of the outer tube, and a central gear coaxially connected to the knob drives the two inner tubes to slide synchronously relative to each other to adjust the circumferential size of the telescopic headband; the malleable joint compression components are, from the inside out, sequentially stacked as an absorbent tissue surface layer, a malleable slow rebound buffer layer, a movable compression insert, and a porous compression base shell.
[0008] Furthermore, the absorbent tissue surface layer is sleeved on the outside of the malleable slow-rebound buffer layer to jointly form a removable cushion assembly; the periphery of the porous pressurized base shell is provided with an inwardly extending retaining edge, and the edge of the removable cushion assembly is removably embedded in the retaining edge.
[0009] Furthermore, the malleable slow rebound buffer layer is a memory foam layer, a slow rebound sponge layer, or other elastic material layer with malleable and buffering functions.
[0010] Furthermore, the two inner tubes are provided with toothed arc-shaped grooves in the area where they overlap in the center of the outer tube. The knob is coaxially connected to a central gear, which meshes with both toothed arc-shaped grooves simultaneously. By rotating the knob, the central gear drives the inner tubes on both sides to extend and retract synchronously.
[0011] Furthermore, the telescopic headband is made of elastic material and provides basic pressure to the temporomandibular joint area through the material's own rebound force; the telescopic headband has symmetrical upward protrusions on both sides to wrap around the auricle and improve wearing comfort.
[0012] Furthermore, the malleable joint compression assembly is connected to the telescopic headband via a hinge, enabling the malleable joint compression assembly to adjust its angle in the coronal plane, thereby adapting to the anatomical morphology and surgical site location of different patients.
[0013] Furthermore, the multi-hole pressurized base shell is a rigid shell structure with multiple mounting holes on its inner side, and the movable pressurized insert is a rigid pressure head configured to be selectively inserted into different holes to adjust the local pressurization position.
[0014] Compared with the prior art, the technical solution of this invention has the following advantages: This invention utilizes a headband-style localized pressure structure to precisely concentrate pressure on the temporomandibular joint surgical area, achieving more precise localized pressure than traditional bandages and elastic headgear. Simultaneously, this invention reduces pressure on the mandibular and chin regions, minimizing adverse effects on mouth opening. Furthermore, the telescopic headband, hinged adjustment structure, and movable pressure insert structure allow for individualized fit for different patients. The detachable soft padding component not only facilitates clinical cleaning, disinfection, and replacement, effectively reducing the risk of cross-infection, but also significantly improves patient comfort during prolonged wear.

[0022] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the invention, and should not be construed as limiting the invention. Rather, embodiments of the invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.
[0023] The following is in conjunction with the appendix Figure 1 To be continued Figure 5 The following describes a head-mounted temporomandibular joint compression device according to an embodiment of the present invention.
[0024] In one embodiment of the present invention, such as Figures 1 to 5 As shown, this invention provides a headband-type postoperative temporomandibular joint compression device, including a telescopic headband 1, a knob 2, and malleable joint compression components 3 disposed at both ends of the telescopic headband 1. Specifically, the telescopic headband 1 consists of an outer tube and two inner tube components 5 extending into the outer tube from the left and right sides respectively, overlapping each other in the central region of the outer tube. The inner tube components 5 and the outer tube components form a sliding rail telescopic engagement structure. The knob 2 is disposed in the central part of the telescopic headband 1 and is used to adjust the circumferential size of the telescopic headband 1 to accommodate patients with different head circumferences. In this embodiment, a central gear 4 is coaxially fixed to the bottom of the knob 2. Both inner tube components 5 have toothed arc-shaped grooves at the overlapping portion in the center of the outer tube. The central gear 4 simultaneously maintains stable engagement with the toothed arc-shaped grooves on both sides of the inner tube components 5. When the knob 2 is turned clockwise or counterclockwise, the central gear 4 rotates coaxially, and using the gear and rack transmission principle, simultaneously drives the inner tube assemblies 5 on both sides to synchronously contract inward or extend outward within the outer tube, thereby achieving precise fine-tuning and locking of the headband's circumferential dimensions. The malleable joint pressure assembly 3 is respectively located at the left and right ends of the telescopic headband 1. Specifically, the malleable joint pressure assembly 3 is hinged to the outer end of the corresponding inner tube assembly 5, and the two are non-detachable. The malleable joint pressure assembly 3 is used to conform to the patient's face after temporomandibular joint surgery and to apply precise selective pressure to the surgical incision and adjacent areas.
[0025] In one embodiment of the present invention, such as Figure 2 and Figure 3As shown, the malleable joint compression assembly 3 mainly includes a porous compression base shell 8, a movable compression insert 7, and a detachable soft pad assembly composed of a malleable slow-rebound buffer layer 9 and a water-absorbing tissue surface layer 10. The porous compression base shell 8 and the telescopic headband 1 are preferably connected by a hinge structure, allowing the malleable joint compression assembly 3 to be adjusted in the coronal plane relative to the telescopic headband 1 to adapt to the anatomical morphology of the temporomandibular joint region and the postoperative incision location of different patients. The inner surface 6 of the porous compression base shell has multiple holes distributed in a matrix. The movable compression insert 7 is a rigid pressure head, one end of which is configured to be selectively inserted into different holes in a plug-in structure to adjust the local compression position. The periphery of the porous compression base shell 8 extends inward to form a retaining edge. The absorbent tissue surface layer 10 is tightly wrapped around the outside of the malleable slow-rebound buffer layer 9 in a sleeve-like shape, and the two together constitute the removable soft pad assembly. This removable soft pad assembly is integrally positioned on the inner side of the movable pressure insert 7, and its circumferential edge is detachably embedded within the retaining edge of the porous pressure base shell 8. Utilizing the mechanical limiting effect of the retaining edge, the soft pad assembly is securely locked inside the base shell, both completely covering the rigid movable pressure insert 7 to provide soft contact and allowing the patient to easily peel it off for cleaning or replacement.
[0026] In one embodiment of the present invention, the telescopic headband 1 provides circumferential support and basic compression for the entire device. Its structure can be adjusted according to the patient's head circumference, thereby ensuring a stable and snug fit when worn. The inner tube 5 is the main cooperating component in the headband telescopic adjustment process, and it slides with the outer tube assembly to change the headband length and adjust the head circumference. Preferably, the telescopic headband 1 has ear-avoidance structures at corresponding positions on both sides of the auricle, so that the headband bypasses the auricle area when worn, reducing direct pressure on the auricle and improving wearing comfort.
[0027] In one embodiment of the present invention, the knob 2 located at the center of the telescopic headband 1 is the core adjustment and operation component of the device. By rotating the knob 2, the user can directly drive the coaxially fixed central gear 4 to rotate synchronously, thereby realizing the synchronous adjustment of the inner tube 5 and the outer tube assembly of the telescopic headband. Since the central gear 4 maintains stable engagement with the toothed arc-shaped grooves at the overlapping parts of the central portions of the inner tubes 5 on both the left and right sides, the rotational motion of the central gear 4 is converted into bidirectional linear displacement of the inner tubes 5 on both sides with the same amplitude, so as to ensure that the adjustment process is smooth and symmetrical, and that the headband can still maintain the stability of the overall structure after adjustment.
[0028] In one embodiment of the present invention, the malleable joint compression component 3 is the core component of the device for achieving localized directional compression. It is disposed at both ends of the telescopic headband 1 and corresponds to the postoperative area of the temporomandibular joint when worn. Through this structure, the basic compression force generated by the headband can be transmitted to the malleable joint compression component 3, and then converted into localized, directional compression for the surgical area through internal components, reducing the extensive compression of non-surgical areas by traditional bandages.
[0029] In one embodiment of the present invention, the porous pressurizing base shell 8 is a rigid structure, which serves to limit the pressurization range and concentrate the pressure output. The inner surface 6 of the porous pressurizing base shell is provided with an installation position that cooperates with the movable pressurizing insert 7. The movable pressurizing insert 7 can be inserted into different positions as needed, thereby changing the specific position of the pressurization point.
[0030] In actual clinical applications, if a patient has only undergone unilateral temporomandibular joint surgery, medical staff or the patient can choose to install the movable pressure insert 7 only on the inside of the porous pressure base shell 8 on the affected side (operated side), and not on the healthy side (non-operated side). In this case, the healthy side only receives a uniformly distributed, gentle base pressure from the removable soft pad assembly to maintain wearing balance; while on the affected side, the movable pressure insert 7 precisely focuses the pressure and pushes it against the surgical incision and adjacent areas.
[0031] In one embodiment of the present invention, the removable soft pad assembly, composed of the malleable slow-rebound buffer layer 9 and the absorbent tissue surface layer 10, is disposed inside the porous pressure base shell 8. This buffer layer is preferably made of an elastic material with slow-rebound properties, so that it can slowly return to its original shape after being compressed, and distribute pressure more evenly during wear, reducing local pressure pain and conforming to the skin. The absorbent tissue surface layer 10 covers the outside of the malleable slow-rebound buffer layer 9, forming a hygienic protective layer that directly contacts the patient's surgical area epidermis. It can efficiently absorb blood, tissue fluid, and sweat seeping from the incision or minimally invasive needle puncture site in the early postoperative period, maintaining a dry and sterile environment in the surgical area. Furthermore, the absorbent tissue surface layer 10 and the malleable slow-rebound buffer layer 9 together constitute a removable soft pad structure, facilitating replacement and cleaning maintenance by the patient as needed.
[0032] like Figure 5As shown, the headband-type postoperative temporomandibular joint compression device of the present invention, in actual wear, has a telescopic headband 1 arranged in a ring shape to surround the wearer's head and provide support and pressure. The malleable joint compression components 3 on the left and right sides of the telescopic headband 1 can be positioned on the left and right sides of the wearer's temporomandibular joint region, respectively. The malleable joint compression components 3 are located on both sides of the head and include compression portions corresponding to the temporomandibular joint region. A malleable slow-rebound buffer layer 9 is provided on the side of the malleable joint compression component 3 facing the human body to improve the fit between the compression component and the human skin surface and enhance comfort during wear.
[0033] The specific usage process of the head-mounted temporomandibular joint postoperative compression device of the present invention is as follows: First, medical staff or patients selectively insert the movable compression insert 7 into the corresponding hole on the inner surface 6 of the multi-hole compression base shell on the affected side, according to the specific geometric trend of the surgical incision on one or both sides of the patient's temporomandibular joint, to pre-lock the target area for high-intensity compression. Next, the telescopic headband 1 is placed on the patient's head as a whole, and its position is finely adjusted so that the upward protrusions on the inner tubes 5 on both sides perfectly bypass and avoid the patient's two auricles. Subsequently, the knob 2 located in the center of the telescopic headband 1 is manually rotated. The knob 2 drives the central gear 4 at the bottom to rotate coaxially, so that the inner tubes 5 on both sides slide synchronously relative to each other within the outer tube, thereby smoothly adjusting the overall circumferential size of the telescopic headband 1 until the device stably fits the patient's head. Since the telescopic headband 1 is made of a highly elastic material, after the size fine-tuning and positioning are completed, the elastic recoil force generated by its stretching will provide continuous, stable and bilaterally symmetrical rigid support and basic clamping force for the entire device.
[0034] Under the transmission of the elastic recoil force, the two malleable joint compression components 3 located at the outer ends of the inner tube 5 are precisely pressed against the temporomandibular joint surgical areas on both sides of the patient. At this time, the porous compression base shell 8 swings freely in the coronal plane relative to the inner tube 5 through a uniaxial hinge structure and finely adjusts its angle, allowing the detachable soft pad assembly to perfectly adapt to and closely conform to the anatomical surface shape of the surgical area. In this state, the movable compression insert 7 on the affected side, supported by a rigid skeleton, generates an inward localized directional pushing force on the detachable soft pad assembly, so that the pressure is highly focused and concentrated on the postoperative surgical incision and its adjacent area, thereby achieving selective and precise directional compression of the surgical area.
[0035] During pressurization, the detachable cushion assembly, composed of the malleable slow-rebound buffer layer 9 and the absorbent tissue surface layer 10, is positioned between the porous pressurizing base shell 8 and the patient's skin. The malleable slow-rebound buffer layer 9 undergoes adaptive micro-deformation, uniformly dispersing and non-invasively buffering the concentrated pressure transmitted by the movable pressurizing insert 7, significantly reducing local pressure pain on the patient's face; simultaneously, the outermost absorbent tissue surface layer 10 continuously and efficiently absorbs postoperative incision ooze and tissue fluid, keeping the surgical area dry and hygienic.
[0036] In summary, the present invention provides a headband-type postoperative temporomandibular joint compression device. It provides overall support and basic compression through a telescopic headband 1 made of elastic material. The hinge structure, in conjunction with the movable compression insert 7, allows for localized directional compression of the surgical area by switching between different holes. Furthermore, the movable compression insert 7 and the hinge adjustment structure enable individualized adjustment of the compression position and angle. This ensures effective postoperative compression while reducing pressure on the mandible, chin, and non-surgical tissues, minimizing the impact on the patient's eating, swallowing, breathing, and mouth opening activities, and improving postoperative comfort and aesthetics.
[0037] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
