Description

Technical Field

[0001] The utility model relates to the technical field of dental instruments, in particular to a filler. Background Art

[0002] In dental treatment, it is necessary to repair the shape of decayed or defective teeth. During the repair, filling materials are needed to fill the teeth. Currently, most dental filling materials are plastic materials such as composite resins and glass ionomer cements. During the filling and repair process, oral filling instruments can pressurize the material to make the filling fit tightly to the tooth, and can also assist in carving the shape of the filling. In actual application, dental filling equipment usually requires the following technologies:

[0003] 1. A handle, usually made of plastic or metal, provides grip.

[0004] 2. The working end is the key part of the filler, which is used to fill the tooth defect with filling material.

[0005] Dental filling accurately fills the missing tooth with filling materials. Existing filling devices (such as patent publication number: CN218832920U) disclose dental filling devices. The functional surface of the first working end matches the occlusal surface of the posterior teeth; the functional surface of the second working end matches the buccal or lingual surface of the posterior teeth. One end of the first and second connecting bodies is fixedly connected to the handle; the other ends are movably connected to the first working end and the second working end respectively. The movable connection can facilitate the integration of multiple dental treatment instruments and save storage space.

[0006] During the process of filling teeth, after filling with materials, a filler is also needed to trim and shape them. Shaping rods are installed at both ends of the filler, and the shaping rods are fixedly connected to the filler. However, both the filler and the shaping rods are support rod designs, and the internal space of the oral cavity is limited, which will limit the staff's tooth trimming angle and operating space. Utility Model Content

[0007] (1) Technical problems solved

[0008] In response to the deficiencies of the existing technology, the present invention provides a filler to solve the problem of fixed connection between the shaping rod and the filler. However, both the filler and the shaping rod are designed as support rods, and the internal space of the oral cavity is limited, which will restrict the staff's technical problems of tooth trimming angle and operating space.

[0009] (2) Technical solution

[0010] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0011] A filler includes a handle body, both ends of the handle body are fixedly mounted with connecting seats, a working end is rotatably mounted inside each connecting seat, both side ends of each working end are fixedly mounted with a fixed shaft, a positioning ring is fixedly mounted on the surface of each fixed shaft, and both side ends of each handle body are slidably mounted with a fixing plate.

[0012] Preferably: each of the two side ends of the fixing plate is fixed with an insertion rod, each of the side ends of the fixing plate is fixedly installed with two telescopic rods, the top of each fixing plate is provided with a positioning groove, each of the two side ends of the handle body is fixedly installed with a clamping seat, a support plate is rotatably installed inside each of the clamping seats, guide rods are fixedly installed on both side ends of the handle body, and a return spring is fixedly installed inside each of the connecting seats.

[0013] (3) Beneficial effects

[0014] 1. By pulling the support plate, the support plate rotates around the top end, the support plate deflects inside the holder, and the end of the support plate leaves the inside of the positioning groove by rotation. The inside of the positioning groove is a concave arc design. The support plate leaves the inside of the positioning groove and rotates the working end to drive the fixed shaft to rotate inside the connecting seat. The fixed shaft is connected to the reset spring, and the working end deflects arbitrarily to the left and right directions. The angles of the two working ends are adjusted to facilitate obtaining more tooth filling and trimming angles inside the oral cavity.

[0015] 2. The rotation angle of the working end is fixed by allowing the fixed plate to drive the insertion rod to dock with the groove on the surface of the positioning ring. At the same time, the fixed plate rubs against the end of the support plate during movement. After the insertion rod is aligned with the positioning ring, the end of the support plate deflects along the inclined surface of the top of the fixed plate, and at the same time guides the support plate into the interior of the positioning groove. The support plate applies lateral support to the fixed plate, allowing the support plate to cooperate with the fixed plate to quickly fix the working end. BRIEF DESCRIPTION OF THE DRAWINGS

The end of the support plate leaves the interior of the positioning groove by rotation. The interior of the positioning groove is a concave arc design. The support plate leaves the interior of the positioning groove and rotates the working end to drive the fixed shaft to rotate inside the connecting seat. The fixed shaft is connected to the return spring, and the working end is arbitrarily deflected to the left and right directions. The angles of the two working ends are adjusted to facilitate obtaining more tooth filling and trimming angles inside the oral cavity.

[0023] Example

[0024] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the technical solution in the embodiment of the present application effectively solves the problem of fixed connection between the shaping rod and the obturator. However, both the obturator and the shaping rod are designed as support rods. The internal space of the oral cavity is limited, which will limit the staff's technical problems of tooth trimming angle and operating space. The overall idea is as follows:

[0025] In response to the problems existing in the prior art, the present invention provides a filler, including a handle body 11, both ends of the handle body 11 are fixedly installed with a connecting seat 12, and a working end 13 is rotatably installed inside each connecting seat 12. By rotating the working end 13, the working end 13 drives the fixed shaft 14 to rotate inside the connecting seat 12. The fixed shaft 14 is connected to the return spring 16. Any deflection of the working end 13 to the left or right will drive the return spring 16 to stretch. At the same time, the working end 13 can only rotate forty-five degrees to both sides inside the connecting seat 12. The two side ends of each working end 13 are fixedly installed with a fixed shaft 14, and the surface of each fixed shaft 14 is fixedly installed with a positioning ring 15. The two side ends of each handle body 11 are slidably installed with a fixed plate 21.

[0026] The two side ends of each fixing plate 21 are fixed with an insertion rod 24, and the side ends of each fixing plate 21 are fixedly installed with two telescopic rods 22. The top of each fixing plate 21 is provided with a positioning groove 23, which is a downwardly concave arc design, and one side of the positioning groove 23 is provided with an inclined surface (the inclined surface smoothly transitions with other areas of the top of the fixing plate 21). The inclined surface is used to guide the end of the support plate 18 to slide into the positioning groove 23 when the fixing plate 21 moves. The two side ends of each handle body 11 are fixedly installed with a card seat 17, and the interior of each card seat 17 is rotatably mounted. A support plate 18 is provided, and guide rods 19 are fixedly installed on both side ends of the handle body 11. A return spring 16 is fixedly installed inside each connecting seat 12. During the movement, the fixed plate 21 rubs against the end of the support plate 18. After the insertion rod 24 is aligned with the positioning ring 15, the end of the support plate 18 deflects along the inclined surface on one side of the positioning groove 23 at the top of the fixed plate 21, and is guided by the inclined surface into the interior of the positioning groove 23. The support plate 18 applies a lateral support to the fixed plate 21, so that the support plate 18 cooperates with the fixed plate 21 to quickly fix the working end 13.

[0027] Working principle:

[0028] The first step is to take the handle 11, and the working ends 13 are installed at both ends of the handle 11. The working end 13 is inserted into the patient's oral cavity to fill and trim the teeth. The support plate 18 is pulled to rotate around the top end. The support plate 18 is deflected inside the base 17. The end of the support plate 18 is rotated to leave the interior of the positioning groove 23. The interior of the positioning groove 23 is a concave arc design. The support plate 18 leaves the interior of the positioning groove 23. By rotating the working end 13, the working end 13 drives the fixed shaft 14 to connect The seat 12 rotates internally, the fixed shaft 14 is connected to the return spring 16, and the working end 13 deflects arbitrarily to the left or right, which will drive the return spring 16 to stretch. At the same time, the working end 13 can only rotate forty-five degrees to both sides inside the connecting seat 12. Through the rotation of the working end 13, the working end 13 squeezes the top of the insertion rod 24 through the positioning ring 15. The top of the insertion rod 24 is an arc-shaped design. The squeezing and pushing of the insertion rod 24 drives the fixed plate 21 to move. The fixed plate 21 moves at the side end of the handle body 11, squeezing the top of the telescopic rod 22, forcing the telescopic rod 22 to compress.

[0029] In the second step, by rotating the working end 13, the working end 13 is deflected inside the connecting seat 12, and the angles of the two working ends 13 on the side ends of the handle body 11 can be adjusted respectively. Through the reverse force of the telescopic rod 22, the telescopic rod 22 is used to apply a thrust to the fixed plate 21, so that the fixed plate 21 drives the plug 24 to dock with the card groove on the surface of the positioning ring 15, and the rotation angle of the working end 13 is fixed. At the same time, the fixed plate 21 rubs against the end of the support plate 18 during the movement, and the connection end of the support plate 18 and the card seat 17 is also installed with a return spring 16. The torsion provided by the return spring 16 always applies a deflection force to the support plate 18, so that the support plate 18 can rotate around After deflecting downward around the base 17 and the insertion rod 24 is aligned with the positioning ring 15, the end of the support plate 18 deflects along the inclined surface of the top of the fixed plate 21, and at the same time guides the support plate 18 into the interior of the positioning groove 23, and applies a lateral support to the fixed plate 21 through the support plate 18, so that the support plate 18 cooperates with the fixed plate 21 to quickly fix the working end 13. At the same time, the two side ends of the working end 13 are connected to the return spring 16. The rotation of the working end 13 drives the return spring 16 to stretch. At the same time, the two return springs 16 can apply reverse tension to the fixed shaft 14, allowing the return spring 16 to drive the fixed shaft 14 to deflect, and adjust the working end 13 to a horizontal state.
