The dental arch may be either an upper or a lower dental arch, without limitation. The fixing member 1 is connected to the dental arch on one side and connected to the first connecting member 2 on the other side, and the first connecting portion 11 is disposed on the side facing away from the dental arch in this embodiment, so that the adhesion between the fixing member 1 and the dental arch and the detachable connection between the fixing member 1 and the first connecting member 2 can be mutually unaffected. The jaw movement of the patient is not affected when the jaw track detection is performed.
As shown in fig. 2, the first connecting member 2 includes a first connecting structure and a second connecting structure, and the first connecting portion 11 of the fixing member 1 is detachably connected to the fixing member 1 through the first connecting structure; the detachable connection of the fixing member 1 and the first connecting member 2 is realized through the first connecting structure in this embodiment, so that the fixing member 1 can be quickly and conveniently detached from the dental motion track tracking device or mounted on the dental motion track tracking device according to the use requirement.
Wherein one end of the second connecting piece 3 is provided with a second connecting part 31, the other opposite end is provided with a third connecting part 32, and the second connecting part 31 is detachably connected with the first connecting piece 2 through a second connecting structure;
wherein the marking element 4 is provided with a plane with a marking pattern 41 at one end and a fourth connecting portion 42 at the opposite end, said fourth connecting portion 42 being detachably connected to the third connecting portion 32.
The marking pattern 41 may be formed of a material having a light reflecting property, so that a recording instrument like an infrared binocular camera can collect an optical signal reflected by the marking pattern 41 on the marking member 4 and acquire the position and posture of the marking member 4 in space according to the optical signal.
As shown in fig. 9, the marking pattern 41 includes 1 central circle 411, at least one ring 412 with a notch, and at least 4 peripheral circles 413, where the central circle 411 is located at the center of the ring 412, and the 4 peripheral circles 413 are distributed outside the ring 412.
Since the marker 4 and the second connector 3 are detachably connected, the marker 4 in this embodiment can be quickly and conveniently detached from the jaw movement track following device or mounted to the jaw movement track following device according to the use requirement. The jaw motion track tracking device of the embodiment enables the fixedly connecting piece 1 and the marking piece 4 to directly form a detachable connection relationship with the jaw motion track tracking device through the connecting parts and the connecting structures in the first connecting piece 2 and the second connecting piece 3. The fixing part 1 matched with the dental arch of different users can be selected according to the shapes and the sizes of the dental arches of the different users, and the selected fixing part 1 is assembled on the dental arch motion track tracking device and is used for matching the fixing part 1 with the dental arch of the users, so that the convenience and the reliability of connection of the dental arch motion track tracking device and the dental arch of the users can be well ensured, and the accuracy of dental arch motion track tracking is provided. Therefore, the jaw movement track tracking device of the embodiment can be well adapted to the requirements of different patients. In addition, since the marker 4 also adopts a detachable structure, the jaw motion track tracking device of the embodiment can flexibly replace various different markers 4 according to application scenes. The same marker 4 can be adopted under the same functional requirement, so that the marker 4 can be reused for different users, and the fixed connector 1 only needs to be replaced for different users, so that the jaw movement track tracking device of the embodiment can also remarkably reduce the cost.
As shown in fig. 3 and 4, in this embodiment, the fastening member 1 further includes a first fastening portion 12 and a second fastening portion 13 formed by extending from two sides of the first connecting portion 11, where the first fastening portion 12 and the second fastening portion 13 enclose a semi-surrounding structure that is recessed toward one side of the first connecting portion 11. Wherein the first fastening portion 12 and the second fastening portion 13 form a substantially semicircular shape to match the shape of the dental arch, so that the adhesion area of the fastening member 1 and the dental arch can be increased, thereby improving the reliability of adhesion. The first connecting portion 11 is located at a side of the first fixing portion 12 and the second fixing portion 13 away from the dental arch, so as not to affect adhesion. The first connecting portion 11 may be located at a middle position of the fixing member 1, and the first fixing portion 12 and the second member portion extend from left and right sides, respectively, so as to better cover a portion of the dental arch to be bonded.

Thus, the reliability of the adhesion between the fixed connection piece 1 and the dental arch can be ensured, and the discomfort caused by the fixed connection piece 1 in the mouth of a user can be reduced.
As an alternative but advantageous embodiment, as shown in fig. 2 and 5, the first connection structure comprises in this embodiment a first receiving cavity 21 in which at least a part of the first connection 11 is located. The embodiment is provided with the accommodating cavity to arrange the connecting part of the fixedly connecting piece 1, so that the influence of the exposure of the connecting part on a patient can be avoided.
As shown in fig. 3 and 4, in order to achieve the convenient and reliable detachable connection between the fixing member 1 and the first connecting member 2, in this embodiment, the first connecting portion 11 includes a first clamping portion 111 and a second clamping portion 112 disposed at two different positions along the first direction, a first protrusion 113 is disposed on a side of the first clamping portion 111 opposite to the second clamping portion 112, a second protrusion 114 is disposed on a side of the second clamping portion 112 opposite to the first clamping portion 111, as shown in fig. 5 and 6, the first connecting structure further includes a first limiting hole 211 and a second limiting hole 212 that are in communication with the accommodating cavity, the first protrusion 113 is clamped into the first limiting hole 211 in the accommodating cavity, and the second protrusion 114 is clamped into the second limiting hole 212 in the accommodating cavity.
In this embodiment, the clamping component fixing member 1 and the first connecting member 2 are respectively disposed at two different positions in the first direction for clamping, so that reliability of clamping can be improved, and a fixed position relationship between the clamping component fixing member 1 and the first connecting member 2 is kept fixed.
As shown in fig. 3 and 4, in order to reliably engage the first engaging portion 111 and the second engaging portion 112 with the first limiting hole 211 and the second limiting hole 212, respectively, the first engaging portion 111 and the second engaging portion 112 may be provided in a structure having a certain elasticity. When in implementation, a groove can be arranged on two sides of the first connecting part 11 along the first direction, the first connecting part 11 of the groove piece is divided into three parts, the main body part of the first connecting part 11 is positioned in the middle, and the first clamping part 111 and the second clamping part 112 are positioned on two sides respectively. The end of the first clamping portion 111 facing away from the first connecting piece 2 is a free end, and the root of the other end is connected with the main body portion, so that the first clamping portion 111 needs to have a certain elasticity, and can be drawn towards the main body portion under the action of an external force to reduce the overall volume of the first connecting portion 11, so that the front end of the first connecting portion 11 can be clamped into the first accommodating cavity 21. Similarly, one end of the second connecting portion, which faces away from the first connecting member 2, is a free end, and the root of the other end is connected with the main body portion, so that the second clamping portion 112 needs to have a certain elasticity, and can be drawn towards the main body portion under the action of external force to reduce the overall volume of the first connecting portion 11, so that the front end of the first connecting portion 11 can be clamped into the first accommodating cavity 21.
