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 teardrop-shaped multifunctional forceps 4 of the present application are used in conjunction with the intermandibular traction nails in the prior art. Figure 1The figure shows a schematic diagram of the structure of the intermandibular traction nail. The intermandibular traction nail includes a traction nail body and a traction nail protective cover 1. The traction nail body includes a traction nail tip, a traction nail cap connected to the traction nail tip, a traction nail neck connected to the traction nail cap, and a traction nail head connected to the traction nail neck. The surface of the traction nail tip is provided with a thread. The traction nail protective cover 1 includes: a protective cover head, a protective cover neck and a protective cover cap body, and a suction cup 2 arranged at the bottom of the protective cover cap body.

[0037] The head of the protective cover is connected with the head of the traction nail 3, the neck of the protective cover is connected with the neck of the traction nail, and the cap of the protective cover is connected with the cap of the traction nail, so that the protective cover body covers the surface of the head, neck and cap of the traction nail. The suction cup 2 is a suction cup 2 with an arc surface, and the suction cup 2 is a thin layer and can adsorb gums. The tissue surface at the bottom of the suction cup 2 and the contact surface with the gums are provided with a long-acting slow-release silver ion material, which exists in the form of a powder mixture.

[0038] After implanting the traction pin in the prior art, it is necessary to frequently clean food residues, eliminate inflammation or replace the antibacterial material at the bottom of the suction cup 2. In the process of oral cleaning, the dental cleaning machine in the prior art often fails to reach the dead corner of the oral cavity, resulting in the inability to remove food residues hidden near the traction pin, causing local inflammatory reactions in the gum tissue, ulcers and obvious pain. In order to solve the above problems, the present invention provides the following technical solutions.

[0039] like Figure 2 , which is a schematic diagram of the three-dimensional structure of a teardrop-shaped multifunctional tweezers 4 in the present invention. The teardrop-shaped multifunctional tweezers 4 include: a control unit 41, and a first tweezer handle 42 and a second tweezer handle 43 connected to the control unit 41.

[0040] The control part 41 of the present invention is a water drop-shaped structure, and a water inlet 45 and a water outlet are arranged on the surface of the control part 41, and a channel connected with the water inlet 45 and the water outlet is arranged inside the control part 41. The water inlet 45 is connected to the water outlet of the irrigator, and the channel is arranged inside the tweezers and has an anti-blocking design and a quick cleaning function, so as to rinse the surgical area before operation.

[0041] In the present invention, the control unit 41 is provided with a gear adjustment device 47 for controlling the opening angle between the first forceps handle 42 and the second forceps handle 43. By adjusting the gear adjustment device 47 of the opening size of the forceps, the gears (0, 1, 2, 3...) can be adjusted sequentially by pressing the gear adjustment device 47, and the structure and shape of the device together with the control unit 41 form a water drop shape.

[0042] The control unit 41 of the present invention is provided with a flushing force control button 46 for controlling the water flow at the working end of the second forceps handle 43. The flushing force control button 46 of the present invention is not limited to using two, three or more gears, and the flushing force control button 46 cooperates with the oral irrigator to realize multiple gears and multiple water flow flushing modes to meet the oral flushing in different scenarios.

[0043] The first forceps handle 42 and the second forceps handle 43 in the present invention are both S-shaped structures. The first forceps handle 42 is a flat-head forceps or has an upper concave surface, and the second forceps handle 43 has a lower concave surface, and a spoon-shaped structure 44 is formed along the lower concave surface toward the working end. Figure 3 The upper concave surface and the lower concave surface of the first tweezers handle 42 and the second tweezers handle 43 can fit each other, that is, the angle between the first tweezers handle 42 and the second tweezers handle 43 is 0, so that the first tweezers handle 42 and the second tweezers handle 43 are easy to store.

[0044] It should be noted that, on the one hand, the S-shaped structure of the second tweezers handle 43 is convenient for the operator to hold and store; on the other hand, the bending part of the S-shaped structure of the second tweezers handle 43 is designed to fit the vertical contact arc of the lip and cheek soft tissue, so that the bending part can form a support with the lip and cheek soft tissue, thereby improving the stability of the second tweezers handle 43 during the cleaning process.

[0045] In the present invention, a lighting device is provided on one side of the first forceps handle 42 close to the second forceps handle 43, which is used to supplement the area that cannot be well illuminated by the dental chair lighting during intraoral operation.

[0046] In the present invention, a built-in channel is provided inside the second tweezers handle 43, one end of the built-in channel is provided with an invisible water outlet, and the other end is connected to the channel. A flow control unit can be provided in the built-in channel to control the water flow speed at the working end of the second tweezers handle 43. The water flow speed is controlled by the flushing force control button 46 of the control unit 41.

[0047] It should be noted that one end of the tweezers in the prior art is flat or has a sharp chamfered edge, which makes the tweezers have a poor supporting effect when releasing the negative pressure of the suction cup 2 and is easy to damage the oral cavity;

[0048] The spoon-shaped structure 44 at the working end of the second tweezers handle 43 of the present invention has a large support surface, which is convenient for relieving the negative pressure of the suction cup 2 when removing the protective cover and reducing sliding. On the other hand, it reduces damage to the oral cavity when prying open the suction cup 2.

[0049] The spoon-shaped structure 44 can be retracted inside, and has a seamless and invisible design when retracted.

[0050] In the present invention, a smooth mirror surface is arranged at the center of the concave surface of the spoon-shaped structure 44 to obtain a local fine field of view. The smooth mirror surface is not limited to circular, elliptical or other special-shaped structures, and is prepared by high polishing.

[0051] The first tweezers handle 42 and the second tweezers handle 43 in the present invention are an integrally formed structure or a split structure. When the first tweezers handle 42 and the second tweezers handle 43 are an integrally formed structure, the first tweezers handle 42 and the second tweezers handle 43 are pressed by the gear adjustment device 47 to control the opening angle between the first tweezers handle 42 and the second tweezers handle 43. When the first tweezers handle 42 and the second tweezers handle 43 are a split structure, the first tweezers handle 42 and the second tweezers handle 43 can be rotatably connected, or at least one of the first tweezers handle 42 and the second tweezers handle 43 is fixedly connected.

[0052] In the present invention, a plurality of grooves 48 are provided on the first tweezers handle 42 and the second tweezers handle 43. The width of the grooves 48 is designed to be slightly larger than the width of the thickest rubber band when it is not stretched. The grooves 48 are perpendicular to the long axis of the working end of the tweezers, so that the rubber band can be fixed by the grain during operation to avoid slipping. In addition, the design of the grooves 48 can fix the angle between the first tweezers handle 42 and the second tweezers handle 43 to improve stability.

[0053] The present invention provides a method for using a water drop-shaped multifunctional tweezers, comprising the following steps:

[0055] S2, connecting the water outlet of the water flosser through the water inlet on the surface of the control part, passing through the channel in the control part and reaching the end of the second tweezers handle; at the same time, the lighting device on the first tweezers handle provides a local field of vision with good lighting;

[0056] S3. The spoon-shaped structure at the working end of the second forceps handle supports the soft tissue surface of the oral cavity and releases the negative pressure of the suction cup when removing the traction pin protective cover.

[0057] Specifically, when the teardrop-shaped multifunctional tweezers 4 of the present invention are in use, the gear adjustment device 47 on the control part 41 controls the opening angle between the first tweezer handle 42 and the second tweezer handle 43, so that one side of the S-shaped structure of the second tweezer handle 43 forms a support with the inner wall of the oral cavity, and a rubber band is set in the corresponding groove 48 to fix the front end of the first tweezer handle 42 and the second tweezer handle 43; the water outlet of the water flosser is connected through the water inlet on the surface of the control part 41, and reaches the end of the water flosser through the second tweezer handle through the channel in the control part 41; the flushing force control button 46 on the control part 41 is used to control the water flow size at the working end of the second tweezer handle 43, and cooperate with the water flosser to realize multi-speed and multi-water flow flushing modes; at the same time, the lighting device on the first tweezer handle 42 provides a local field of vision with good lighting, which is convenient for cleaning; when it is necessary to disassemble the suction cup, the soft tissue surface of the oral cavity is supported by the spoon-shaped structure at the working end of the second tweezer handle 43, and the negative pressure of the suction cup 2 is released when the protective cover is removed.

[0058] The present invention provides a storage box, which is a teardrop-shaped structure, and the inner wall of the storage box is provided with a concave surface, which fits the surface of the second forceps handle 43. The storage box is made of the same material as the first forceps handle 42, the second forceps handle 43 and the traction pin, preferably a titanium alloy material.

[0059] 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.
