Therefore, features defined as "first", "second", etc. may explicitly or implicitly include one or more of the features. In the description of the invention, unless otherwise specified, "multiple" means two or more.

[0035] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood by specific circumstances.

[0036] The protective cover provided by the present invention is suitable for use with an intermaxillary traction nail. The structure of the intermaxillary traction nail is as follows: Figure 1 As shown, it includes: a traction nail tip 4, a traction nail cap body 3 connected to the traction nail tip 4, a traction nail neck 2 connected to the traction nail cap body 3, and a traction nail head 1 connected to the traction nail neck 2. The surface of the traction nail tip 4 is provided with threads, the traction nail head 1 is an arc-shaped structure and is smoothly arranged, and the traction nail neck 2 is a smooth cylindrical structure. In order to solve the problem of contact friction between the traction nail cap body 3 and the lip and cheek mucosa in the prior art, the following embodiments are proposed.

[0037] Embodiment 1

[0038] like Figure 2 and 3 , which is a schematic diagram of the three-dimensional structure of a multifunctional traction nail protective cover in the present invention. The multifunctional traction nail protective cover comprises: a protective cover body 5 and an anti-slip member 6 arranged below the protective cover body.

[0039] The outer shape of the protective cover body 5 is consistent with the outer surface shape of the intermaxillary traction nail, and is a convex hollow structure. From top to bottom, it includes: a protective cover head 51, a protective cover neck 52 and a protective cover cap body 54.

[0040] The protective cover head 51 is connected to the head of the traction nail, the protective cover neck 52 is connected to the neck of the traction nail, and the protective cover cap body 54 is connected to the cap body of the traction nail, so that the protective cover body 5 covers the surface of the head, neck and cap body of the traction nail.

[0041] In the present invention, the protective cover head 51, the protective cover neck 52 and the protective cover cap body 54 are all made of soft materials that are close to the oral mucosa, which reduces the friction when the protective cover body 5 contacts the oral surface mucosa, reduces discomfort, and prevents mucosal rupture. The present invention further provides a slow-release silver ion antibacterial coating on the surface of the protective cover body 5, so that the protective cover body 5 has a long-term antibacterial and antibacterial effect, thereby reducing local oral mucosal traumatic ulcers and local infections. In addition, the protective cover body 5 in the present invention has a certain rigidity and toughness as a whole, which is convenient for quick pressing into place and removal.

[0042] The present invention provides an anti-slip component 6 at the bottom of the protective cap body 54, and the anti-slip component 6 is an annular structure. Furthermore, since the diameter of the tip of the traction nail 4 gradually decreases along the length direction, the anti-slip component 6 is designed to be an annular structure with a diameter that gradually decreases from one end to the other end. In order to facilitate the installation of the anti-slip component 6, a thread is provided inside the anti-slip component 6 to cooperate with the thread on the surface of the traction nail tip 4. When the anti-slip component 6 is against the bottom of the protective cap body 54, it can prevent the protective cap body 54 from warping after long-term use, and form reinforcement at the turning point to improve the fit rate between the protective cap body 5 and the traction nail.

[0043] In this embodiment, a suction member 7 for adsorption to the gums can be provided at the bottom of the anti-slip member 6. The suction member 7 is a suction disk with an arc-shaped surface. The suction member 7 is a thin layer and can adsorb the gums. The transparent design can show whether there is food residue below so that it can be cleaned in time. The tissue surface at the bottom of the suction disk and the contact surface with the gums are provided with a long-acting sustained-release silver ion material, which is not the coating structure of the protective cover body 5 mentioned above, but exists in the form of a powder mixture or the like. The design of the suction member 7 in this embodiment improves the stability of the traction pin and the gums on the one hand, and enhances the antibacterial and antimicrobial properties on the other hand.

[0044] Embodiment 2

[0045] When the traction pins in the prior art are used, different traction pin necks 2 are connected by a plurality of rubber bands, so that traction force is formed between the traction pins; however, the traction pin neck 2 is a smooth cylindrical structure, which will cause the rubber band to be directly exposed on the surface of the traction pin neck 2, and the rubber band will directly contact the gums, so that the traction rubber band often compresses the gum tissue to cause ulcers and obvious pain. In order to solve this problem, the present invention makes the following improvements on the basis of the first embodiment.

[0046] like Figure 4 As shown, a plurality of accommodating grooves 53 are provided on the surface of the protective sleeve neck 52, and the depth of the accommodating grooves 53 is at least greater than the diameter of the rubber band. On the one hand, the accommodating grooves 53 form an accommodating cover for the rubber band, thereby reducing the direct contact between the rubber band and the gums, thereby fundamentally avoiding the rubber band from compressing the gum tissue and reducing the pain. On the other hand, the surface of the accommodating grooves 53 can form a large static friction with the rubber band, thereby ensuring stability and anti-slipping, and avoiding misalignment of the rubber band.

[0047] In this embodiment, the receiving groove 53 is a threaded structure. In order to achieve as many traction directions as possible, the thread rotation direction is selected to be consistent, but the thread rotation angles are multiple. In the actual preparation process, a threaded structure with a thread rotation angle can be prepared on the same protective cover neck 52, or a threaded structure with multiple thread rotation angles can be prepared on the surface of the same protective cover neck 52.

[0048] In this embodiment, two cable-like devices with continuously adjustable positions, lengths or directions can be designed to adjust the position and angle of the rubber band near the traction pin to prevent the rubber band from compressing the gingival tissue and the subsequent exposure of the alveolar bone surface and even alveolar bone absorption.

[0049] Embodiment 3

[0050] Since the traction pins in the prior art cannot accurately regulate the pressure or traction force when used, they are generally determined through clinical experience, but with many errors. Therefore, this embodiment makes improvements based on the above-mentioned embodiment 1 and / or embodiment 1.

[0051] In this embodiment, a pressure sensing element is disposed between the protective cover head 51 and the head of the traction nail, and the pressure sensing element is in contact with and connected to the protective cover head 51 .

[0052] The head 51 of the protective cover serves as a direct action surface of the pressure sensing element and can be selected to be a plane, a spherical surface or a concave arc surface.

[0053] The pressure sensing member includes: a force-bearing member, a force-applying member connected to the force-bearing member, a thin sheet arranged between the force-bearing member and the force-applying member, and a pressure sensor connected to the thin sheet. One side of the force-bearing member is configured to be in surface contact with the protective cover head 51, and the other side is configured to be a plane and in contact with the force-applying member and the thin sheet. One side of the force-applying member is configured to be a plane and in surface contact with the above-mentioned thin sheet, and the other side is configured to be a concave arc structure and in surface contact with the traction nail head 1, thereby improving the comfort and convenience of the process.

[0054] In this embodiment, a traction force sensing component is provided between the neck portion 52 of the protective cover and the neck portion of the traction nail, and the traction force sensing component is fixedly connected to the neck portion 52 of the protective cover.

[0055] The traction force sensing component is a micro-sensing and sensing system with force size and direction, which can be realized by assembling the tension sensor in the prior art and used for real-time monitoring of the traction force value of the rubber band.

[0056] The protective cover head 51 is provided with a display unit, which is electrically connected to the pressure sensing element and the traction sensing element, so that the display unit can display the magnitude and direction of the traction force on the intermaxillary traction nail in real time, thereby realizing precise regulation of pressure or traction force.

[0057] The above is based on the ideal embodiment of the present invention. Through the above description, relevant personnel can make various changes and modifications without departing from the technical concept of the present invention. The technical scope of the present invention is not limited to the content in the specification, and the technical scope must be determined according to the scope of the claims.
