[0026] Embodiments
[0027] As Figures 1 to 5 The utility model provides an oral cavity prosthetic expansion device, including a pair of support block 1 and the lower jaw support 11 and upper jaw support 12 of rotation connection on its expansion oral cavity, the lower jaw support 11 and upper jaw support 12 all are fixedly connected with arc pad 121, arc pad 121 adopts rubber pad, its effect is that patient oral cavity bites the lower jaw support 11 and upper jaw support 12 and increases comfort. The end of lower jaw support 11 and upper jaw support 12 all are rotationally connected with the both ends of support block 1, a pair of sleeve 2 are fixedly connected on lower jaw support 11, and sleeve 2 is slightly inclined and set on lower jaw support 11. The end of sleeve 2 away from lower jaw support 11 all are slidingly connected with the telescopic strut 23 of abutting upper jaw support 12, and the inside of sleeve 2 is equipped with the reset spring 24 of making telescopic strut 23 automatically expand upper jaw support 12, and the reset spring 24 is making not to pinch the lower jaw support 11 and upper jaw support 12 will automatically expand to the limit angle. The one end of reset spring 24 is fixedly connected with the inner wall of sleeve 2, and the other end of reset spring 24 is fixedly connected with the end of telescopic strut 23;The sliding slot 21 of being set on sleeve 2, and the end outer wall of telescopic strut 23 is fixedly connected with the support sleeve 3.
[0028] Among them, as Figures 2 to 5 The locking mechanism is automatically fixed in the sliding slot 21, and the locking mechanism comprises a plurality of linearly arranged tooth grooves 22 formed in the sliding slot 21, and a telescopic groove 37 and a limiting groove 38 are formed in the support sleeve 3 in communication. The inside of the telescopic groove 37 is slidingly connected with the clamping teeth 31 clamped into the tooth groove 22, and the clamping teeth 31 are arranged in the sliding slot 21, so that the telescopic strut 23 can automatically come out of the sleeve 2, but it will be clamped when it is retracted. The clamping teeth 31 are provided with an arc-shaped clamping head 32 which is automatically retracted into the support sleeve 3 after abutting against the tooth groove 22, and the arc-shaped clamping head 32 is used to move the telescopic strut 23 out of the sleeve 2, and after the clamping teeth 31 abut against the tooth groove 22, the clamping teeth 31 will be automatically retracted into the support sleeve 3. The inside of the limiting groove 38 is provided with a connecting block 33, and one end of the connecting block 33 is fixedly connected with the clamping teeth 31.
[0029] In addition, as Figure 5 The locking mechanism further comprises a pushing spring 36 arranged in the support sleeve 3, and the pushing spring 36 is used to automatically release the clamping teeth 31 from the support sleeve 3. One end of the pushing spring 36 is fixedly connected with the inner wall of the support sleeve 3, and the other end of the pushing spring 36 is fixedly connected with the clamping teeth 31.
[0030] It is worth mentioning that, as Figure 2 And Figure 5 One end of the connecting block 33 away from the clamping teeth 31 is fixedly connected with a sliding knob 34, and a plurality of anti-skid grooves 35 are formed in the end of the sliding knob 34 away from the connecting block 33, and the anti-skid grooves 35 are used to increase the friction when the fingers or tools contact the sliding knob 34, so as to avoid sliding.
[0031] Further, as Figure 1 ,Figure 3 and Figure 4 As shown, a pair of rotating seats 122 are fixedly connected to the upper jaw support 12, and the rotating seats 122 are rotatably connected to the ends of the corresponding telescopic support rods 23.
[0032] In this embodiment, when using an oral prosthodontic expander, such as Figure 1 As shown, first manually pinch the lower jaw support 11 and the upper jaw support 12 and place them into the mouth, then let the lower jaw support 11 and the upper jaw support 12 lock onto the corresponding upper and lower teeth. Then, simply release pinching the lower jaw support 11 and the upper jaw support 12, and simultaneously open the mouth slightly. At this time, the upper jaw support 12 is not locked by the teeth, and the telescopic support rod 23, through the elastic thrust of the return spring 24 inside the sleeve 2, slides out along the sleeve 2. The end of the telescopic support rod 23 near the upper jaw support 12 is connected to the rotating seat 122 to expand the upper jaw support 12, thus allowing the expanded lower jaw support 11 and the upper jaw support 12 to automatically adapt to a comfortable size for the patient's mouth opening. Simultaneously, the telescopic support rod 23 drives the support sleeve 3 to slide within the groove 21, and the arc-shaped locking head 32 on the locking tooth 31, through the elastic thrust of the return spring 24, automatically retracts into the support sleeve 3 after pressing against the tooth groove 22. Furthermore, the locking tooth 31 will also engage with the corresponding tooth groove 22 by pushing the elastic force of the spring 36, thereby preventing the mouth from closing involuntarily.
[0033] When using the dental reamer, simply move a pair of sliding buttons 34 simultaneously. This causes the corresponding connecting block 33 to slide along the limiting groove 38, which in turn causes the corresponding retaining tooth 31 to retract into the support sleeve 3. At this time, the retaining tooth 31 cannot engage with the tooth groove 22 on the sliding groove 21. The teeth in the mouth can then bite down on the lower jaw support 11 and upper jaw support 12 to reduce the opening angle of the lower jaw support 11 and upper jaw support 12, making it easy to remove them from the mouth. This method is quick and easy to use.
[0034] The preferred embodiments of this utility model described above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
