Description

Technical Field

[0001] This utility model relates to the field of oral medical devices, specifically a retrograde filling device for periapical surgery. Background Technology

[0002] Root canal treatment is one of the most common treatments in dentistry. Although modern root canal treatment has a high success rate, some treatments still fail due to persistent intracanal infection and extraapical infection. In cases of failed root canal treatment, apical surgery can be used to save the affected tooth. The three key steps of apical surgery are apicoectomy, apical preparation, and apical filling. Because the apex is located within the bone window prepared in the alveolar bone, the space is narrow, and the patient's lips can obstruct the view, making the procedure difficult and requiring specialized instruments. The apical filling step often uses bioceramic material delivery devices and apical filling appliances. Bioceramic material delivery devices have the disadvantage of complex structures, as illustrated in the utility model patent with authorization number CN220588378U; while apical filling appliances have the disadvantage of limited functionality, requiring multiple instruments for different tooth positions. For example, the utility model patent with authorization number CN210384079U designs three instruments for anterior and posterior teeth. Summary of the Invention

[0003] The proposed technical problem is to address the shortcomings of existing retrograde filling instruments for apical surgery, which have complex structures and limited functions.

[0004] The technical solution of this utility model is as follows: A retrograde filling instrument for apical surgery includes a first and a second filling head, a first and a second connecting rod, a handle and a transport head. The first and second filling heads are connected to the first connecting rod and are located on both sides of the first connecting rod. The first connecting rod is connected to one end of the handle, and the other end of the handle is connected to the second connecting rod. The second connecting rod is connected to the transport head.

[0005] Furthermore, the filling head is arc-shaped with a circular tip section, and the plane containing the arc of the two filling heads forms a 90-degree angle with the long axis of the handle.

[0006] Furthermore, the handle surface has anti-slip texture.

[0007] Furthermore, the second connecting rod is arc-shaped at the connection point with the transfer head, and the plane of the arc is parallel to the line connecting the tips of the first filling head and the second filling head.

[0008] Furthermore, both the upper and lower surfaces of the transfer head are triangular or rhomboid.

[0009] The beneficial effects of this utility model are: the retrograde filling instrument for apical surgery has the advantages of simple structure and multiple functions. The transfer head can carry the pre-formed paste apical retrograde filling material to the cut root surface, and the two filling heads are suitable for retrograde filling operations in all tooth positions.

[0014] The present invention will be further described below with reference to the accompanying drawings and embodiments. The described embodiments are merely some embodiments of the present invention, and not all embodiments. Other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are all within the scope of protection of the present invention.

[0015] Example: See Figure 1 2, 3, A retrograde filling instrument for apical surgery, comprising a first filling head 1, a second filling head 2, a first connecting rod 3, a second connecting rod 5, a handle 4, and a transfer head 6. The first filling head 1 and the second filling head 2 are connected to the first connecting rod 3 and are located on both sides of the first connecting rod 3, respectively. The first connecting rod 3 is connected to one end of the handle 4, and the other end of the handle 4 is connected to the second connecting rod 5. The second connecting rod 5 is connected to the transfer head 6.

[0016] Furthermore, the filling heads 1 and 2 are arc-shaped with circular tip sections, and the plane containing the arc of the two filling heads 1 and 2 forms a 90-degree angle with the long axis of the handle 4.

[0017] Furthermore, the surface of the handle 4 has anti-slip texture 7.

[0018] Furthermore, the second connecting rod 5 is arc-shaped at the connection point with the transfer head 6, and the plane of the arc is parallel to the line connecting the tip 8 of the first filling head and the tip 9 of the second filling head.

[0019] Furthermore, the upper and lower surfaces of the transfer head 6 are both triangular or rhomboid.

[0020] In use, the dentist shapes the paste-like root apical retrofill material into a pointed strip and places it on a mixing plate. The upper and lower surfaces of the transfer head 6 are triangular or rhomboid. The tip of the transfer head is used to scoop up the appropriate size of the retrofill material and transfer it to the root resection surface of the bone window. It is then pressed into the prepared retrofill cavity. The first filling head 1 or the second filling head 2 is then used to compact the retrofill material. For right-handed dentists, the first filling head 1 is used for the mandibular anterior teeth, the left mandibular posterior teeth, and the right mandibular posterior teeth, while the second filling head 2 is used for the upper anterior teeth, the left mandibular posterior teeth, and the right mandibular posterior teeth. Because the plane of the arc of the second connecting rod 5 connecting the handle 4 and the transfer head 6 is parallel to the line connecting the tip 8 of the first filling head and the tip 9 of the second filling head, the transfer head 6 can point towards or away from the surgical area when compacting the retrofill material using the first filling head 1 or the second filling head 2, making it less likely to injure the operator's hand.

[0021] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solution of this utility model, and these modifications or equivalent substitutions cannot cause the modified technical solution to deviate from the scope of the technical solution of this utility model.
