Description

Technical Field

[0001] The utility model belongs to the technical field of dental implants, and in particular relates to a bone powder filling device for dental implants. Background Art

[0002] In today's life, some people have damaged teeth due to bad eating habits. In order to avoid the harassment of tooth pain, many people choose to extract the bad teeth and then implant them. However, many people's oral structure will cause some dental implants to have poor stability. In order to solve this problem, many hospitals will be equipped with bone powder for repair before implantation, so there is a dental implant bone powder filling device.

[0003] When the tooth implant bone powder filling device is used, the bone powder is mixed with the donated blood in the oral cavity of the person to be implanted, and then pushed to the location where the bone powder is to be supplemented;

[0004] However, when using today's dental implant bone powder filling devices, the medical staff have to work harder when filling because the location of the bone powder to be added is relatively precise. Utility Model Content

[0005] The purpose of the utility model is to provide a tooth implant bone powder filling device to solve the problem mentioned in the above background technology that when using the current tooth implant bone powder filling device, the position of the bone powder to be supplemented is relatively fine, and the medical staff has a high work intensity when filling.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a tooth implant bone powder filling device, comprising a tube body, a limiting ring is sleeved on the outer side of the tube body, limiting rods are fixed on both sides of the limiting ring, and a slide groove is arranged inside the limiting rod, a slider is slidably connected inside the slide groove, a rotating groove is arranged inside the slider, and a rotating column is rotatably connected inside the rotating groove, and a connecting column is arranged on the top of the rotating column, and a positioning buckle is rotatably connected to the top of the connecting column.

[0007] Preferably, a pulling column is slidably connected inside the tube body, and a piston that fits the tube body is fixed at the end of the pulling column.

[0008] Preferably, the outer side of the connecting column is provided with an external thread, and the connecting column is rotatably connected to the rotating column via the thread, and the inner wall of the positioning buckle is provided with a silicone pad.

[0009] Preferably, the front view of the tube body is an isosceles trapezoidal structure.

[0010] Preferably, a rubber ring is provided on the inner wall of the limiting ring, and a bearing is provided inside the limiting ring.

[0011] Compared with the prior art, the beneficial effect of the utility model is: by setting a limit ring sleeve on the outside of the tube body, the positions of the two sets of sliders in the slide groove are adjusted, and then the positioning buckles are used to fix the good teeth on both sides of the implanted teeth. After that, the medical staff can adjust the outlet position of the tube body under the action of the positioning buckles, and then adjust the filling position, while reducing the pulling strength of the medical staff, thereby greatly expanding its scope of use.

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] See also Figure 1-Figure 3 The utility model provides a tooth implant bone powder filling device, comprising a tube body 1, a limiting ring 3 is sleeved on the outer side of the tube body 1, limiting rods 4 are fixed on both sides of the limiting ring 3, and a slide groove 5 is arranged inside the limiting rod 4, and a slider 6 is slidably connected inside the slide groove 5, so as to facilitate the adjustment of the position of the slider 6, a rotating groove 7 is arranged inside the slider 6, and a rotating column 8 is rotatably connected inside the rotating groove 7, and a connecting column 9 is arranged on the top of the rotating column 8, and damping is arranged at the connection position to facilitate the adjustment of the rotation angle of the connecting column 9, and a positioning buckle 10 is rotatably connected to the top of the connecting column 9, and the positioning buckle 10 cooperates with the tooth to complete the connection;

[0018] In the present embodiment: bone powder is mixed with the blood inside the oral cavity of the patient to be implanted, the mixed bone powder is pumped into the tube body 1, and then the limiting ring 3 is sleeved on the outside of the tube body 1, and the positions of the two sets of positioning buckles 10 are adjusted under the mutual cooperation of the slider 6 and the slide groove 5, so that the positioning buckles 10 are connected to the good teeth on both sides of the teeth to be implanted, completing the overall connection, and then the position of the discharge port on one side of the tube body 1 can be changed by pulling and rotating the tube body 1, so that the filling effect is better and the pulling strength of the medical staff is reduced.

[0019] See also Figure 1 The inside of the tube body 1 is slidably connected with a pull column 2, and the end of the pull column 2 is fixed with a piston that fits the tube body 1. The pull column 2 drives the piston to move so as to push the bone powder mixture;

[0020] In this embodiment, the feeding and discharging of the bone meal mixture are completed by pulling and pushing the pulling column 2.

[0021] See also Figure 2 and 3 The outer side of the connecting column 9 is provided with an external thread, and the connecting column 9 is rotatably connected with the rotating column 8 through a thread, so that the connecting column 9 is convenient to disassemble. The inner wall of the positioning buckle 10 is provided with a silicone pad, which has deformability and can better fit the teeth to complete the overall fixation;

[0022] In this embodiment: under the action of the thread, the connection column 9 and the positioning buckle 10 are conveniently replaced. Because they are in contact with the patient and are disposable medical devices, the other parts of the limit ring can be disinfected afterwards, and the two sets of positioning buckles 10 can be adjusted at the same time to complete the fixation of the tube body 1.
