Description

Technical Field

[0001] This utility model relates to the field of dental instruments, and in particular to a forceps-type tooth fragment breaking device. Background Technology

[0002] In the extraction of impacted mandibular third molars, the root is often close to the mandibular nerve canal, making a single extraction risky. The best approach is to separate the crown and extract only the crown, allowing the root to detach from the mandibular nerve canal before elective extraction. This significantly reduces the risk of nerve damage. In the removal of vertically impacted and slightly mesial impacted teeth, the crown cannot be divided along the cervical region in one go due to limitations in the cutting angle. The traditional method involves using a high-speed dental handpiece with a cutting bur to create a cross-shaped or radial cutting groove within the crown, dividing it into multiple independent segments. Then, using non-specialized instruments such as dental elevators, external force is applied to these segments to break them off from the cervical region, thus preserving the root intact.

[0003] Traditional tooth fragment breaking tools have the following drawbacks: poor operational safety, lack of buffer protection design, difficulty in controlling the force when applying breaking force, and the instantaneous excessive reaction force can directly impact the operator's hand, causing hand fatigue or injury. At the same time, if the operator applies too much force at once, the tooth fragment can easily break and fly away or the instrument can slip, damaging the patient's oral cavity.

[0004] Therefore, it is necessary to provide a clamp-type tooth block breaking device to solve the above-mentioned technical problems. Utility Model Content

[0005] This invention provides a clamp-type tooth block breaking device, which solves the problem of poor safety in the operation of traditional tools.

[0006] To solve the above-mentioned technical problems, the present invention provides a clamp-type tooth block breaking device, which includes a rotating component. The front and rear parts of the rotating component are respectively rotatably connected to a first rotating disk and a second rotating disk. A connecting rod is fixedly installed on the lower part of the first rotating disk and the lower part of the second rotating disk. A rigid beak is fixedly installed on the opposite side of the two connecting rods.

[0007] Preferably, a first rotating frame is fixedly connected to the lower right side of the first rotating disk, and a first finger ring is fixedly connected to one side of the first rotating frame; a second rotating frame is fixedly connected to the upper right side of the second rotating disk, and a second finger ring is fixedly connected to one side of the second rotating frame.

[0008] Preferably, the first rotating frame has a movable slot, the movable slot has a movable connecting mechanism inside, and a buffer mechanism is fixedly installed on the top of the connecting mechanism.

[0009] Preferably, the connecting mechanism includes a movable block located inside the movable groove. An L-shaped frame is fixedly connected to the front of the movable block, and a threaded rod is threadedly connected to the front of the L-shaped frame. A fixed disc is rotatably connected to one end of the threaded rod located at the rear of the L-shaped frame.

[0010] Preferably, the buffer mechanism includes a buffer frame, the bottom of the buffer frame is fixedly connected to the top of the movable block, a sliding block is slidably connected between the two sides of the inner wall of the buffer frame, a buffer rod is fixedly connected to the top of the sliding block, the top end of the buffer rod passes through the buffer frame and extends to the outside of the buffer frame, and a buffer spring is fixedly connected between the two sides of the bottom of the sliding block and the two sides of the bottom of the inner wall of the buffer frame.

[0011] Preferably, the surfaces at the junction of the first and second rotating disks are both smooth surfaces.

[0012] Compared with related technologies, the clamp-type tooth block breaking device provided by this utility model has the following beneficial effects: This invention provides a clamp-type tooth block breaking device. The connecting mechanism can be adjusted in position by the smooth sliding of the moving block in the moving groove, and then locked by the threaded rod and the fixed plate. It can flexibly adapt to the size of the tooth block and adjust the closing angle between the first rotating frame and the second rotating frame. Different sizes of tooth blocks can be processed without changing tools, greatly expanding the applicability of the device. The elastic deformation of the buffer spring in the buffer mechanism generates a reverse force. On the one hand, it absorbs the reaction force when the tooth block is broken, avoiding the impact force from being directly transmitted to the operator's hand and reducing hand fatigue. On the other hand, the elastic resistance controls the speed of force application, preventing the operator from applying too much force at once, effectively avoiding the tooth block from breaking and flying, and protecting the patient's oral mucosa and gingival tissue.

[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0016] Please refer to the following: Figure 1 , Figure 2 , Figure 3 and Figure 4 ,in, Figure 1 A schematic diagram of a preferred embodiment of the clamp-type tooth block breaking device provided by this utility model; Figure 2 for Figure 1 A schematic diagram of the overall rear view structure shown; Figure 3 for Figure 1 The diagram shows the structure of the connecting mechanism. Figure 4 for Figure 1 The schematic diagram of the buffer mechanism is shown. The clamp-type toothed block breaking device includes a rotating part 1. The front and rear parts of the rotating part 1 are respectively rotatably connected to a first rotating disk 2 and a second rotating disk 3. The lower parts of the first rotating disk 2 and the lower parts of the second rotating disk 3 are both fixedly installed with connecting rods 4. Rigid beaks 5 are fixedly installed on opposite sides of the two connecting rods 4. The rigid beak 5 is made of high-hardness tungsten steel. The rotating part 1 consists of a rotating shaft and two limiting sleeves. The two limiting sleeves are respectively fitted on both ends of the rotating shaft to limit the axial displacement of the first rotating disk 2 and the second rotating disk 3 on the rotating shaft, so as to avoid deviation during rotation. A first rotating frame 6 is fixedly connected to the lower right side of the first rotating disk 2, and a first finger ring 7 is fixedly connected to one side of the first rotating frame 6. A second rotating frame 8 is fixedly connected to the upper right side of the second rotating disk 3, and a second finger ring 9 is fixedly connected to one side of the second rotating frame 8. The first rotating frame 6 has a moving groove 10, and the moving groove 10 has a movable connecting mechanism 11 inside. A buffer mechanism 12 is fixedly installed on the top of the connecting mechanism 11. The movable groove 10 is a rectangular through groove; The connecting mechanism 11 includes a movable block 111, which is located inside the movable groove 10. An L-shaped frame 112 is fixedly connected to the front of the movable block 111, and a threaded rod 113 is threadedly connected to the front of the L-shaped frame 112. A fixed plate 114 is rotatably connected to one end of the threaded rod 113 located at the rear of the L-shaped frame 112. The fixing plate has a circular structure and is made of rubber to prevent scratches on the surface of the first rotating frame 6 during fixing; The buffer mechanism 12 includes a buffer frame 121, the bottom of which is fixedly connected to the top of the moving block 111. A sliding block 122 is slidably connected between the two sides of the inner wall of the buffer frame 121. A buffer rod 123 is fixedly connected to the top of the sliding block 122. The top end of the buffer rod 123 passes through the buffer frame 121 and extends to the outside of the buffer frame 121. Buffer springs 124 are fixedly connected between the two sides of the bottom of the sliding block 122 and the two sides of the bottom of the inner wall of the buffer frame 121. The surfaces at the junction of the first rotating disk 2 and the second rotating disk 3 are both smooth surfaces, which reduces the frictional resistance when the two rotating disks rotate relative to each other and extends their service life.

[0017] The working principle of the clamp-type tooth block breaking device provided by this utility model is as follows: First, push the movable block 111 by hand to slide it in the movable groove 10, causing the connecting mechanism 11 and the buffer mechanism 12 to move as a whole until the buffer rod 123 of the buffer mechanism 12 can effectively contact the second rotating frame 8 during operation; then rotate the threaded rod 113 clockwise, and the threaded rod 113 moves backward along the threaded hole of the L-shaped frame 112, causing the fixed plate 114 to approach the surface of the first rotating frame 6 until the fixed plate 114 is tightly attached to the surface of the first rotating frame 6, completing the position locking of the connecting mechanism 11, ensuring that the buffer mechanism 12 is stable in subsequent operations, thereby adjusting the closable angle between the first rotating frame 6 and the second rotating frame 8 according to the size of the tooth block; The operator inserts their fingers into the first finger ring 7 and the second finger ring 9 respectively, and inserts the two rigid beaks 5 into the cutting groove of the tooth block. The first rotating frame 6 and the second rotating frame 8 drive the first rotating disk 2 and the second rotating disk 3 to rotate around the rotating component 1, causing the two rigid beaks 5 to open. The operator continues to apply force to close the finger rings, and applies a breaking force to the tooth block through the rigid beaks 5. The tooth block gradually deforms until it breaks along the cutting groove. During the application of force, the second rotating frame 8 contacts the top of the buffer rod 123 and applies pressure. The buffer rod 123 moves into the buffer frame 121, causing the sliding block 122 to compress the buffer spring 124. The elastic deformation of the buffer spring 124 generates a reverse force, which absorbs the reaction force when the tooth block breaks, preventing the impact force from being directly transmitted to the operator's hand and reducing hand fatigue. On the other hand, the elastic resistance controls the speed of force application, preventing the operator from applying too much force at once, effectively preventing the tooth block from shattering and flying, and protecting the patient's oral mucosa and gingival tissue.

[0018] Compared with related technologies, the clamp-type tooth block breaking device provided by this utility model has the following beneficial effects: The connecting mechanism 11 can be smoothly adjusted in position by sliding the movable block 111 in the movable groove 10, and then locked by the threaded rod 113 and the fixed plate 114. It can be flexibly adapted to the length, diameter and other dimensions of the tooth block, and can handle tooth blocks of different specifications without changing tools, which greatly expands the applicability of the device. The elastic deformation of the buffer spring 124 in the buffer mechanism 12 will generate a reverse force. On the one hand, it absorbs the reaction force when the tooth block breaks, avoids the impact force from being directly transmitted to the operator's hand, and reduces hand fatigue. On the other hand, it controls the speed of force application through elastic resistance, preventing the operator from applying too much force at once, effectively avoiding the tooth block from breaking and flying, and protecting the patient's oral mucosa and gingival tissue.
