Description

Technical Field

[0001] The utility model belongs to the technical field of tooth viscous bone preparation, in particular to a synchronous delivery mechanism for preparing viscous bone by mixing tooth bone powder with PRF clear liquid. Background Art

[0002] After tooth loss, alveolar bone will inevitably undergo bone resorption. With the development of social economy, more and more patients with missing teeth tend to use dental implants to repair missing teeth. For missing teeth repair, PRF liquid extracted from the patient's own blood is mixed with bone powder to prepare viscous bone to fill the patient's groove. Currently, dentists prepare it by first adding all the bone powder, and then adding PRF liquid through a syringe to stir. This operation method has the disadvantage of uneven mixing of bone powder and PRF liquid. The bone powder and PRF liquid are added in batches, which requires dentists to frequently replace the bone powder storage box and PRF liquid syringe, which is less convenient to operate. Summary of the invention

[0003] The technical problem to be solved by the utility model is to improve a synchronous delivery mechanism for preparing viscous bone which is easy to operate and can evenly mix tooth bone powder and PRF clear liquid.

[0004] In order to solve the above technical problems, the present invention is achieved through the following technical solutions: a mechanism for synchronous delivery of viscous bone prepared by mixing tooth bone powder with PRF clear liquid, comprising a base, a support rod, a top plate, a pressure plate, a rack, a rotating shaft, a carrier plate, a sleeve, a transmission screw, a handwheel and a screw sleeve, wherein the support rod is fixedly mounted on the base, the top plate is fixedly mounted on the top of the support rod, the pressure plate is slidably mounted on the support rod, the carrier plate is fixedly mounted on the support rod, the carrier plate is located at the lower part of the pressure plate, a connecting plate is fixedly mounted in the middle of the support rods on the front and rear sides, the rotating shaft is rotatably mounted on the connecting plate, gears are fixedly sleeved on both sides of the rotating shaft, and the two lower parts of the pressure plate are fixedly mounted on the connecting plate. A rack is fixedly installed on the side, and the rack is meshed with the gear for transmission connection. The lower part of the rack is slidably installed in the base, and the sleeve is fixedly installed on the rotating shaft. A first clamping bolt is threadedly installed on the sleeve, and a through hole is provided on the carrier plate. A second clamping bolt connected to the through hole is threadedly installed on the carrier plate, and a screw sleeve is fixedly installed on the top plate, and the transmission screw is threadedly installed in the screw sleeve. The lower part of the transmission screw is rotatably connected to the pressure plate through a ball bearing, and the handwheel is fixedly installed on the upper end of the transmission screw, and the lower end of the rack slides through the carrier plate. A feeding hole is also provided on the carrier plate, and the feeding hole is located directly below the sleeve.

[0005] Furthermore, a rubber pad is fixedly installed at the lower part of the pressing plate, and the rubber pad is located just above the through hole of the carrier plate.

[0006] Furthermore, the hand wheel is fixedly covered with an anti-skid rubber sleeve.

[0007] Furthermore, a guide sleeve is fixedly mounted on the pressing plate, and the guide sleeve is slidably mounted on the supporting rod.

[0008] Compared with the prior art, the advantages of the present invention are: this mechanism can realize the synchronous feeding of dental bone powder and PRF clear liquid into the shaping tray. The dentist turns the hand wheel with one hand to control the downward movement of the pressure plate, thereby controlling the feeding speed and timing, and uses the other hand to stir and mix the dental bone powder and PRF clear liquid in the shaping tray to prepare viscous bone. This can ensure that the dental bone powder and PRF clear liquid are mixed evenly, so that the quality of the prepared viscous bone is better, and has the advantages of simple operation and easy use.

[0011] The utility model is described in detail below in conjunction with specific implementation methods:

[0012] like Figure 1 The device for synchronously delivering viscous bone prepared by mixing tooth bone powder with PRF clear liquid as shown comprises a base 1, a support rod 2, a top plate 3, a pressure plate 4, a rack 42, a rotating shaft 5, a carrier plate 6, a sleeve 7, a transmission screw 9, a hand wheel 91 and a screw sleeve 92, wherein the support rod 2 is fixedly mounted on the base 1, the top plate 3 is fixedly mounted on the top of the support rod 2, the pressure plate 4 is slidably mounted on the support rod 2, the carrier plate 6 is fixedly mounted on the support rod 2, the carrier plate 6 is located at the lower part of the pressure plate 4, a connecting plate is fixedly mounted in the middle of the support rod 2 on the front and rear sides, the rotating shaft 5 is rotatably mounted on the connecting plate, gears are fixedly sleeved on both sides of the rotating shaft 5, racks 42 are fixedly mounted on both sides of the lower part of the pressure plate 4, the racks 42 are meshed and transmission connected with the gears, and the lower part of the rack 42 It is slidably installed in the base 1, and the sleeve 7 is fixedly installed on the rotating shaft 5. A first clamping bolt 71 is threadedly installed on the sleeve 7. A through hole is provided on the carrier plate 6, and a second clamping bolt 61 connected to the through hole is threadedly installed on the carrier plate 6. A screw sleeve 92 is fixedly installed on the top plate 3, and the transmission screw 9 is threadedly installed in the screw sleeve 92. The lower part of the transmission screw 9 is rotatably connected to the pressure plate 4 through a ball bearing, and the retaining frame of the ball bearing is fixedly installed on the pressure plate 4. The rotating body of the ball bearing at the lower end of the transmission screw 9 is fixedly connected, and the handwheel 91 is fixedly installed on the upper end of the transmission screw 9. The lower end of the rack 42 slides through the carrier plate 6. A feeding hole is also provided on the carrier plate 6, and the feeding hole is located directly below the sleeve 7.

[0013] A rubber pad 41 is fixedly installed at the lower part of the pressing plate 4. The rubber pad 41 is located just above the through hole of the carrier plate 6. The rubber pad 41 can not only play a role in height compensation, but also increase the friction force on the top of the push rod of the syringe 8 to avoid sliding displacement between the top of the push plate and the pressing plate 4.

[0014] The hand wheel 91 is fixedly covered with an anti-skid rubber sleeve to increase the friction when the operator rotates the hand wheel 91 , making it easier to rotate the hand wheel 91 .

The shaping disk 10 is placed on the top of the base 1, and the transmission screw 9 is rotated by the handwheel 91 to push the pressing plate 4 to move downward along the support rod 2. The rack 42 drives the rotating shaft 5 and the sleeve 7 to rotate through the gear. At this time, the top of the sleeve 7 is flipped outward to pour the bone powder stored therein, and the poured bone powder passes through the feeding hole on the carrier plate 6 and falls into the shaping disk 10. At the same time, the pressing plate 4 squeezes the push rod of the syringe 8, so that the PRF clear liquid stored therein drips into the shaping disk 10, and the dentist uses tools to stir and mix the bone powder and PRF clear liquid in the shaping disk 10 to prepare viscous bone.
