Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a dental implant bone powder filler for oral restoration. Background Technology

[0002] Dental implants are a rapidly developing new technology in oral medicine. They refer to a method of tooth restoration that uses a substructure implanted into the bone tissue to support and retain the upper tooth prosthesis. It is also one of the increasingly popular restoration methods after tooth loss. A primary condition for successful dental implantation is to ensure that there is enough alveolar bone in the implantation area, which requires filling the alveolar bone with bone powder using a bone powder filler.

[0003] The existing device requires manual reset after feeding, and uneven feeding force can easily lead to bone powder overflow or insufficient filling, affecting filling accuracy. At the same time, the filler is prone to shaking in the oral cavity, which not only affects the stability of operation, but may also compress oral tissues and cause patient discomfort.

[0004] Therefore, those skilled in the art have provided a dental implant bone powder filler for oral restoration to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies and provide a dental implant bone powder filler for oral restoration. The resettable feeding mechanism can smoothly push bone powder to avoid overflow or insufficient filling. Its reset function facilitates continuous operation and ensures stable feeding to improve filling accuracy. The limiting mechanism can adjust the position of the oral support seat to adapt to different oral cavity conditions, providing stable support to prevent the filler from shaking. The fixing structure prevents displacement and reduces pressure on oral tissues. The combination of these two features improves the stability, accuracy, efficiency, and patient comfort of dental implant bone powder filling.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A dental implant bone powder filling device for oral restoration includes a bone powder filling cylinder, one end of which is fixedly connected to a discharge cylinder, a resettable pushing mechanism is provided inside the bone powder filling cylinder, and a limiting mechanism is provided on the outer wall of the bone powder filling cylinder.

[0008] The resettable feeding mechanism includes a movable rod. A reset groove is provided on one side of the inner wall of the upper and lower ends of the bone powder filling cylinder. A fixed rod is fixedly connected between the inner walls of the two reset grooves. A reset spring is movably sleeved on one side of the outer wall of the two fixed rods. A movable sleeve is movably sleeved on the other side of the outer wall of the two fixed rods. The movable rod is fixedly connected to the two movable sleeves. A feeding piston is fixedly connected to one end of the movable rod. The feeding piston is movably disposed inside the bone powder filling cylinder.

[0009] The above technical solution enables the feeding and automatic reset of bone powder through the resettable feeding mechanism. When the moving rod is pushed, the moving sleeve slides along the fixed rod, driving the feeding piston to move and push bone powder in the bone powder filling cylinder. After being released, the reset spring rebounds to reset the moving sleeve, thereby driving the feeding piston back to the initial position, which facilitates continuous operation.

[0010] Furthermore, the limiting mechanism includes a fixed threaded collar, and a No. 1 external threaded collar and a No. 2 external threaded collar are fixedly sleeved on one side of the outer wall of the bone powder filling cylinder. The outer wall of the No. 2 external threaded collar is threaded with an inner and outer threaded collar, and an oral cavity support seat is fixedly connected to the upper and lower parts of the outer wall of one side of the inner and outer threaded collar.

[0011] Through the above technical solution, the position of the oral cavity support can be flexibly adjusted by the set limiting mechanism. That is, the internal and external threaded collar and the No. 2 external threaded ring are threaded together. When rotated, the position can be changed, which drives the oral cavity support to move to adapt to the internal oral space of different patients and provide stable support for the filler.

[0012] Furthermore, the fixed threaded collar is threaded onto the outer wall of the first external threaded collar and the inner and outer threaded collar, and the threads inside the fixed threaded collar are arranged opposite to the threads inside the inner and outer threaded collar;

[0013] The above technical solution securely locks the positions of the inner and outer threaded collars by using a fixed threaded collar. That is, by using a thread design in opposite directions, when the fixed threaded collar is tightened, it can be tightly connected to both the first outer threaded collar and the inner and outer threaded collars at the same time, preventing the inner and outer threaded collars from loosening or shifting during operation.

[0014] Furthermore, the first external threaded ring and the second external threaded ring are fitted together.

[0015] The above technical solution provides a continuous threaded connection base for the fixed threaded collar by fitting the No. 1 external threaded ring and the No. 2 external threaded ring together, ensuring that the fixed threaded collar can stably cooperate with both at the same time, thus enhancing the connection firmness of the overall structure.

[0016] Furthermore, the end of the moving rod away from the pusher piston passes through the bone meal filling cylinder to the outside and is fixedly connected to a pusher head, the diameter of which is the same as the diameter of the bone meal filling cylinder;

[0017] The above technical solution facilitates the operation of the moving rod by medical staff through the push head. Its design with the same diameter as the bone powder filling cylinder can prevent hand slippage when pushing, and at the same time, it can limit the range of movement of the moving rod to prevent excessive pushing.

[0018] Furthermore, the two ends of the reset spring are respectively fixedly connected to the inner wall of the movable sleeve and the reset groove on one side, and the reset spring is made of carbon steel.

[0019] The above technical solution utilizes a carbon steel return spring, which possesses excellent elasticity and toughness. The fixed connection at both ends ensures that it can stably provide return force, maintaining its performance even after multiple extensions and retractions, thus guaranteeing the reliable return of the pusher piston.

[0020] Furthermore, the upper end face of the bone meal filling cylinder is provided with an injection port, and a sealing plug is fitted inside the injection port;

[0021] The above technical solution allows for convenient addition of bone powder into the bone powder filling cylinder via the designated injection port. The sealing plug prevents bone powder from leaking out of the injection port during the filling process and also prevents external impurities from entering, ensuring the cleanliness of the bone powder.

[0022] This utility model has the following beneficial effects:

[0023] 1. The dental implant bone powder filler proposed in this utility model can achieve stable bone powder delivery by adding a resettable pushing mechanism, avoiding bone powder overflow or insufficient filling caused by uneven pushing force. In addition, the reset function of the pushing piston facilitates continuous filling operation without manual reset, saving operation time. Furthermore, the cooperation between the fixed rod and the moving sleeve ensures stable pushing direction, prevents piston deviation and bone powder residue, and improves filling accuracy.

[0024] 2. The dental implant bone powder filling device for oral restoration proposed in this utility model, through the addition of a limiting mechanism, allows the oral support seat to be adjusted in position according to the size of the patient's oral cavity, stably supporting the inner wall of the oral cavity, preventing the filling device from shaking during operation, and improving operational stability. The reverse thread design of the fixing threaded collar can enhance the fixation effect, prevent the support seat from shifting and affecting the filling accuracy, and the fit between the support seat and the oral cavity can reduce the pressure on the oral tissues during operation, improving patient comfort.

[0025] 3. The dental implant bone powder filling device proposed in this utility model has a resettable feeding mechanism that can smoothly push bone powder to avoid overflow or insufficient filling. Its reset function facilitates continuous operation and can also ensure stable feeding to improve filling accuracy. The limiting mechanism can adjust the position of the oral support seat to adapt to different oral cavity conditions, stabilize the support to prevent the filling device from shaking, and fix the structure to prevent displacement and reduce pressure on oral tissues. The combination of the two improves the stability, accuracy, efficiency and patient comfort of dental implant bone powder filling. Attached Figure Description

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of specific embodiments. Obviously, the described specific embodiments are only a part of the specific embodiments of the present invention, and not all of them. Based on the specific embodiments of the present invention, all other specific embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Reference Figure 1 , Figure 2 and Figure 3 This utility model provides a specific embodiment: a dental implant bone powder filler for oral restoration, including a bone powder filling cylinder 1, a discharge cylinder 2 fixedly connected to one end of the bone powder filling cylinder 1, a resettable pushing mechanism 3 provided inside the bone powder filling cylinder 1, a limiting mechanism 4 provided on the outer wall of the bone powder filling cylinder 1, and an injection port 5 opened on the upper end face of the bone powder filling cylinder 1. A sealing plug 6 is fitted inside the injection port 5. Bone powder can be easily added into the bone powder filling cylinder 1 through the injection port 5. The sealing plug 6 can prevent bone powder from leaking out of the injection port 5 during the filling process, and at the same time prevent external impurities from entering, ensuring the cleanliness of the bone powder.

[0035] The resettable feeding mechanism 3 includes a movable rod 301. Reset grooves 304 are provided on one side of the inner wall of both the upper and lower ends of the bone powder filling cylinder 1. Fixed rods 305 are fixedly connected between the inner walls of both sides of the two reset grooves 304. Reset springs 306 are movably sleeved on one side of the outer wall of each of the two fixed rods 305, and movable sleeves 307 are movably sleeved on the other side of the outer wall of each of the two fixed rods 305. The movable rod 301 is fixedly connected to the two movable sleeves 307. A feeding piston 303 is fixedly connected to one end of the movable rod 301. The feeding piston 303 is movably disposed inside the bone powder filling cylinder 1. The resettable feeding mechanism 3 enables the feeding and automatic reset of bone powder. When the movable rod 301 is pushed, the movable sleeve 307 slides along the fixed rod 305, causing the feeding piston 303 to move and push bone powder within the bone powder filling cylinder 1. After release, the reset spring 306 rebounds, causing the movable sleeve 307 to reset. The pusher piston 303 is driven back to its initial position for easy continuous operation. The end of the moving rod 301 away from the pusher piston 303 passes through the bone powder filling cylinder 1 to the outside and is fixedly connected to the pusher head 302. The diameter of the pusher head 302 is the same as the diameter of the bone powder filling cylinder 1. The pusher head 302 makes it easier for medical staff to operate the moving rod 301. Its design with the same diameter as the bone powder filling cylinder 1 can avoid hand slippage when pushing, and at the same time, it can limit the range of movement of the moving rod 301 to prevent excessive pushing. The two ends of the return spring 306 are fixedly connected to the inner wall of the moving sleeve 307 and the return groove 304 respectively. The return spring 306 is made of carbon steel. The return spring 306 made of carbon steel has good elasticity and toughness. The fixed connection at both ends ensures that it can stably provide return force and maintain its performance after multiple extensions and retractions, ensuring the reliable return of the pusher piston 303.

[0036] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5The limiting mechanism 4 includes a fixed threaded collar 405. A first external threaded collar 401 and a second external threaded collar 402 are fixedly sleeved on one side of the outer wall of the bone powder filling cylinder 1. An inner and outer threaded collar 403 is threadedly sleeved on the outer wall of the second external threaded collar 402. Oral support seats 404 are fixedly connected to the upper and lower parts of one side of the outer wall of the inner and outer threaded collars 403. The limiting mechanism 4 allows for flexible adjustment of the position of the oral support seat 404. That is, the inner and outer threaded collars 403 and the second external threaded collar 402 are threadedly engaged, and their position can be changed during rotation, causing the oral support seat 404 to move to adapt to the oral cavity space of different patients, providing stable support for the filling device. The fixed threaded collar 405 is threadedly sleeved on the first external threaded collar 401 and the inner and outer threaded collars 403. On the outer wall, the threads inside the fixed threaded collar 405 are arranged in the opposite direction to the threads inside the inner and outer threaded collars 403. The fixed threaded collar 405 can securely lock the position of the inner and outer threaded collars 403. That is, by using the thread design in opposite directions, when the fixed threaded collar 405 is tightened, it can be tightly connected with the first outer threaded collar 401 and the inner and outer threaded collars 403 at the same time, preventing the inner and outer threaded collars 403 from loosening or shifting during operation. The first outer threaded collar 401 and the second outer threaded collar 402 are fitted together. The fitted arrangement of the first outer threaded collar 401 and the second outer threaded collar 402 provides a continuous threaded connection basis for the fixed threaded collar 405, ensuring that the fixed threaded collar 405 can stably cooperate with both at the same time, enhancing the connection firmness of the overall structure.

[0037] Working principle: This device achieves precise bone powder filling through the coordinated action of a resettable feeding mechanism 3 and a limiting mechanism 4. In use, bone powder is first added to the bone powder filling cylinder 1 through the injection port 5, and the sealing plug 6 is tightened. When adjusting the limiting mechanism 4, the inner and outer threaded collar 403 is rotated to move along the second outer threaded collar 402, driving the oral cavity support seat 404 to the appropriate oral cavity support position. Then, the fixing threaded collar 405 is tightened (utilizing the reverse thread engagement with the first outer threaded collar 401 and the inner and outer threaded collar 403) to fix its position, ensuring the filler is stably placed in the oral cavity. When filling with bone meal, the pusher head 302 is pushed to move the moving rod 301. The moving rod 301 slides along the fixed rod 305 in the reset groove 304 via the moving sleeve 307, causing the pusher piston 303 to move forward in the bone meal filling cylinder 1, pushing the bone meal from the discharge cylinder 2 to the implantation site. After the pusher head 302 is released, the carbon steel reset spring 306 rebounds, driving the moving sleeve 307, the moving rod 301 and the pusher piston 303 to reset, so that the next filling operation can be carried out. The whole process achieves stable pushing of bone meal and stable support of the device through mechanical structure linkage.
