Description

Technical Field

[0001] This utility model relates to the technical field of dental pulp extraction devices, and in particular to a dental pulp extraction fixation device. Background Technology

[0002] There is a need in the existing technology for the primary extraction and preservation of dental pulp stem cells for future use. Extraction of dental pulp stem cells requires removing the dental pulp from the tooth, separating and culturing the stem cells. During the extraction process, the tooth is clamped with forceps, and then a high-speed dental handpiece is used to cut and grind the tooth flat to extract the pulp. The tooth is not securely fixed, causing interruptions during the process, and it cannot fix teeth of various shapes, and is prone to splintering. Therefore, there is a need for a device to fix the tooth during the extraction of dental pulp tissue. Patent application number 201720129998.4 discloses a device for fixing the tooth during the separation of dental pulp tissue. This device uses mechanical fixation to prevent the tooth from falling off. However, the mechanical clamps are too tight, causing excessive force on the tooth during extraction and resulting in splintering, which affects the extraction of dental pulp. Utility Model Content

[0003] To address the technical problems existing in the prior art, this utility model provides a dental pulp extraction and fixation device.

[0004] To achieve the above objectives, this utility model proposes a pulp extraction and fixation device, comprising: a first swing arm, a first clamping part, a second swing arm, and a second clamping part. The first swing arm and the second swing arm are hinged together. The first swing arm has the first clamping part at its end, and the second swing arm has the second clamping part at its end corresponding to the first clamping part. Swinging the first swing arm and the second swing arm causes the first clamping part and the second clamping part to align and clamp the tooth. The first swing arm has a first locking buckle at its end away from the first clamping part, and the second swing arm has a second locking buckle that cooperates with the first locking buckle. This device is simple in structure, easy to use, and low in cost. It is also universally applicable. By swinging the first and second swing arms, the clamping parts at their ends are used to fix teeth of various shapes. The locking mechanism at the tail secures the fixed position, preventing over-clamping and excessive force on the teeth during pulp extraction, thus preventing tooth fragmentation. It also solves the problems of insufficient tooth fixation and inability to adapt to various tooth shapes when using pliers. This makes it more conducive to tooth grinding and pulp extraction, while also preventing tooth fragmentation, improving the quality of extracted pulp, reducing bacterial contamination, and increasing production efficiency. It is suitable for large-scale production of dental pulp stem cells.

[0005] As an optional implementation, in the pulp extraction and fixation device provided by this utility model, the first clamping part includes a first bracket, a first adjusting part, and an enamel tape measure fixator. The first bracket is located at the end of the first swing arm, and the first adjusting part is connected to the first bracket by a thread. The end of the first adjusting part is provided with the enamel tape measure fixator. By setting the first adjusting part, the distance of the enamel tape measure fixator for fixing the teeth can be adjusted, which is convenient for use.

[0006] As an optional implementation, in the pulp extraction and fixation device provided by this utility model, the second clamping part includes a second bracket, a second adjusting part, and a root fixator. The second bracket is disposed at the end of the second swing arm, and the second adjusting part is threadedly connected to the second bracket. The root fixator is disposed at the end of the second adjusting part. The root fixator is connected to the enamel tape measure fixator to fix the tooth. The distance between the root fixator and the enamel tape measure fixator is adjusted by setting the first adjusting part and the second adjusting part to facilitate clamping and fixing the tooth.

[0007] As an optional implementation, in the pulp extraction and fixation device provided by this utility model, the root fixator includes multiple elastic clips. The multiple elastic clips are used to wrap the root of the tooth. By setting multiple elastic clips to wrap the root of the tooth, the tooth is prevented from flying after fixation, thus achieving a good fixation effect.

[0008] As an optional implementation, in the pulp extraction and fixation device provided by this utility model, the first and second locking buckles are provided with multiple locking teeth. The first and second locking buckles are locked by the locking teeth. After the first clamping part and the second clamping part are connected and fixed to the tooth, the locking teeth on the buckle are used to position the first swing arm and the second swing arm to play a positioning and fixing role, preventing the first clamping part and the second clamping part from being over-clamped, and preventing the tooth from being subjected to excessive force and splashing during the pulp extraction process.

[0009] As an optional implementation, in the pulp extraction and fixation device provided by this utility model, both the first swing arm and the second swing arm are provided with grips to facilitate gripping.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: The dental pulp extraction and fixation device provided by this utility model has a simple structure, is easy to use, and has low cost. At the same time, this instrument is universal. By swinging the first and second swing arms, the clamping parts at their ends are driven to fix teeth of various shapes. The fixed position is then locked by the lock at the tail to prevent the mechanical clamp from clamping too tightly. This prevents the teeth from being subjected to excessive force and splashing during the extraction of dental pulp. It also solves the problems of insufficient tooth fixation and inability to adapt to various tooth shapes when using pliers to clamp teeth. It is more conducive to tooth grinding and dental pulp extraction. At the same time, it can prevent tooth splashing, improve the quality of extracted dental pulp, reduce bacterial contamination, improve production efficiency, and is suitable for large-scale dental pulp stem cell production.
