These drawings and written descriptions are not intended to limit the scope of the concept of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION
[0037] The exemplary embodiments will be described in detail herein with reference to the accompanying drawings. In the following description, the same numbers refer to the same elements throughout the drawings, unless otherwise represented. The embodiments described in the following exemplary embodiments do not represent all the embodiments consistent with the present application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the present application, as detailed in the appended claims.
[0038] In the prior art, in the field of dentistry, a dental filler (also known as a dental filling material) is a material used to repair tooth structure, commonly used to treat dental caries or tooth damage. With the increasing emphasis on oral health and the continuous progress of dental technology, the research and application of dental fillers are also developing.
[0039] The existing dental filler includes a handle, a connecting rod and a contact head, one end of the connecting rod is fixedly connected with the handle, the other end is hingedly connected with the contact head, and the contact head is used to transport the filling material. By changing the angle between the contact head and the connecting rod, multi-angle filling of the filling material is achieved.
[0040] However, the above scheme needs to realize multi-angle filling, but since the connecting rod and the handle cannot be disassembled, a new tooth filler needs to be replaced for each patient, causing great waste.
[0041] In addition, different sizes of contact heads are also needed in some tooth filling operations. For example, if the range of caries is large and a large amount of filling material is needed, a large size contact head needs to be used; if the range of caries is small and a small amount of material is needed, a small size contact head needs to be used. The existing method is usually to place multiple tooth fillers of different sizes on the instrument table for use, but multiple tooth fillers occupy a large space on the instrument table, which is not conducive to the placement of other surgical instruments.
[0042] Based on the above problems, the tooth filler with a detachable contact head is provided to facilitate the replacement of the contact head. The present embodiment will be further described below with reference to the accompanying drawings.
[0043] As shown in Figure 1 , it is a structural schematic diagram of the tooth filler provided by the present application. Figure 1

[0049] The first connecting rod 200 is inserted into the handle 100, and after the first connecting rod 200 is removed, the contact head 400 is also removed, so that a new set of contact head 400 components can be replaced to continue work. Usually, a handle 100 is equipped with multiple contact head 400 structures, and the contact head 400 is set to different sizes as needed.
[0050] The second connecting rod 300 and the contact head 400 can both rotate to realize the adjustment of different angles.
[0051] For example, a spherical joint connection can be used between the first connecting rod 200 and the second connecting rod 300. The end of the first connecting rod 200 is provided with a ball socket, which is a groove structure. The first end of the second connecting rod is provided with a ball head. The ball head cooperates with the ball socket to ensure that the ball head can smoothly rotate in the ball socket to realize the multi-angle rotation of the second connecting rod 300.
[0052] Exemplarily, the contact head 400 and the second end of the second connecting rod 300 can also adopt the spherical joint connection as described above.
[0053] The diameter of the spherical head is 5-10 mm.
