Background technique

Dental filling is a common dental treatment method. By filling some dental fillings in the affected area, the therapeutic effect of making the teeth can be used normally is achieved. Fillings are generally liquid, and most of them are applied to the affected area with a scraper. If the tooth pores to be supplemented are deep, air bubbles may be generated inside, which will affect the treatment effect.

Utility model content

The technical problem to be solved by the utility model is to realize a filling device that is easy to use and prevents the filling from producing steam drums.

In order to achieve the above purpose, the technical solution adopted by the utility model is: dental filling auxiliary filling device, including a handle, a connecting rod and a rubber injection head, the handle and the rubber injection head are respectively fixed at both ends of the connecting rod, and the rubber injection head The outer end of the head is in the form of a tapered frustum that gradually decreases, and an injection cavity that runs through the rubber injection head is provided inside. A piston is provided in the injection cavity, and a connecting cable channel is provided in the connecting rod and the handle. The handle is provided with a chute arranged along the cable channel, a slider is fixed on the chute, the slider is embedded in the cable channel, a cable is provided in the cable channel, and one end of the cable The piston is connected, the other end is connected with the slider, and a vibration unit is arranged in the handle.

The piston is provided with a vibration transmission needle placed in the injection chamber.

The vibration transmission needle is a needle-like structure made of rubber.

The handle is provided with a joint cavity, and one end of the connecting rod is provided with a joint ball placed in the joint cavity.

The rubber injection head is a transparent rubber body.

The utility model has the advantages of simple structure and convenient use, and it is convenient for doctors to fill teeth at any position without generating air bubbles, which helps doctors improve the quality of tooth filling.

The following is a brief description of the content expressed in each piece of drawings in the specification sheet of the utility model and the marks in the figure:

Fig. 1 is a schematic diagram of the structure of a dental filling auxiliary filling device;

The marks in the above figures are: 1. handle; 2. connecting rod; 3. rubber injection head; 4. slider; 5. cable; 6. piston; 7. vibration unit.

Detailed ways

As shown in Figure 1, the dental filling auxiliary filling device includes a handle 1, a connecting rod 2 and a rubber injection head 3, wherein the handle 1 and the rubber injection head 3 are respectively fixed on both ends of the connecting rod 2, and the outer end of the rubber injection head 3 is gradually The reduced frustum-shaped structure, the rubber injection head 3 is provided with an injection cavity through the rubber injection head 3, and the injection cavity is equipped with a piston 6, which constitutes a device that can fill the medicine in the form of injection, which is convenient for controlling the filling rhythm and filling volume. The truncated cone structure is convenient for aligning the filling part, and the rubber injection head 3 is a transparent rubber body, which is convenient for observing the injection volume.

The handle 1 is provided with a joint cavity, and one end of the connecting rod 2 is provided with a joint placed in the joint cavity, so that the angle between the connecting rod 2 and the handle 1 can be adjusted as required, which is convenient for doctors to operate.

The connecting rod 2 and the handle 1 are provided with a connected cable channel, and the handle 1 is provided with a chute arranged along the cable channel, and a slider 4 is fixed on the chute, and the slider 4 is embedded in the cable channel. There is a cable 5 in the channel, one end of the cable 5 is connected to the piston 6, and the other end is connected to the slider 4, so that when the slider 4 is pushed and pulled, the piston 6 can be driven to move, so as to realize the suction and injection (filling) of the filling agent. Adopting the drag cable 5 as the force transmission mechanism is also for adapting to the bent handle 1 and connecting rod 2 .

The handle 1 is equipped with a vibration unit 7, which includes electronic components such as a vibration motor, a battery, and a controller. Vibration during the filling process can effectively avoid the generation of air bubbles and improve the quality of filling. In order to further reduce the possibility of air bubbles The piston 6 is equipped with a vibration transmission needle placed in the injection cavity, and the vibration transmission needle faces the outer end, that is, when the piston 6 is pushed to the end of the stroke, the vibration transmission needle is located outside the rubber injection head 3, and can be inserted into the filled Into the filling in the tooth, through the transmission of vibration, the bubbles that have been generated in the filling are eliminated. The vibration transmission needle is a needle-like structure made of rubber, which can avoid damage to the tooth during the vibration.

The present invention has been exemplarily described above in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited by the above-mentioned manner, as long as various insubstantial improvements are carried out by adopting the method concept and technical solutions of the present invention, or without Improvements that directly apply the concept and technical solutions of the present invention to other occasions are within the protection scope of the present utility model.
