Description

Technical Field

[0001] This utility model relates to the field of oral medicine technology, specifically to an auxiliary tool for the posterior tooth resin filling stamp method. Background Technology

[0002] Posterior dental caries (dental caries) is one of the most common diseases in oral clinical practice, making timely and comprehensive treatment particularly important. Currently, the most commonly used treatment method in clinical practice is composite resin filling (dental filling). Composite resin has excellent physical, chemical, mechanical, and biological properties, enabling good retention and realistic color of the filling. For a long time, resin filling has been carried out using the traditional "layered molding" method. This method requires dentists to have good knowledge of anatomical morphology and operational skills, and the operation time is relatively long to achieve good aesthetic shape and function after the filling. In recent years, the "stamp method" of resin filling has emerged. It uses a suitable material to form a "stamp" of the occlusal surface of the posterior tooth. During the resin filling, the "stamp" is used to restore the original occlusal anatomical and occlusal morphology of the tooth as much as possible, and its clinical efficacy is significant.

[0003] In the stamp method, to prevent the prepared stamp from sticking to the filling resin, a separating material, such as plastic wrap or PTFE tape, needs to be placed between the stamp and the resin. However, in actual operation, the patient's cheeks and tongue can obstruct the placement of the stamp, making it difficult for the operator to place the stamp in the accurate position. This not only reduces the efficiency of the operation but may also affect the filling effect due to inaccurate stamp placement, resulting in problems such as poor filling shape and poor marginal fit, which in turn affects the patient's treatment outcome and oral health.

[0004] Therefore, there is a need to provide an auxiliary tool for the posterior tooth resin filling stamp method. Utility Model Content

[0005] The purpose of this invention is to provide an auxiliary tool for the posterior tooth resin filling stamp method, in order to solve the problem mentioned in the background art that, during actual operation, the patient's cheeks and tongue in the oral cavity can obstruct the placement of the stamp, making it difficult for the operator to place the stamp in the accurate position. This not only reduces the efficiency of the operation, but may also affect the filling effect due to inaccurate stamp placement, resulting in problems such as poor filling shape and poor marginal fit, which in turn affects the patient's treatment effect and oral health.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary tool for the posterior tooth resin filling stamp method, comprising two pressing rods, a shaft assembly fixedly installed at one end between the two pressing rods, a tweezer assembly for gripping fixedly installed at one end of the shaft assembly, an adjustment component installed inside the tweezer assembly, a connecting component rotatably installed at one end of the tweezer assembly, and a blocking component for blocking the inner cheek and tongue engaged on the outside of the tweezer assembly.

[0007] Preferably, the shaft assembly includes two mounting plates, which are respectively fixedly mounted on one end of two pressing rods. A rotating seat is fixedly mounted on each of the two mounting plates, and a rotating shaft is rotatably mounted between the two rotating seats. A torsion spring is mounted on the outside of the rotating shaft, and the two ends of the torsion spring are in contact with the two mounting plates.

[0008] Preferably, the tweezers assembly includes a first sliding shell and a second sliding shell, which are respectively fixedly installed at one end of two mounting plates. Two sliding blocks are slidably installed inside the first sliding shell, and a top clamping rod is fixedly installed at one end of each of the two sliding blocks. Two bottom clamping rods are slidably installed inside the second sliding shell, and a connecting seat is fixedly installed at both ends of one side of each of the two bottom clamping rods.

[0009] Preferably, the adjustment assembly includes multiple adjustment holes and two lead screws. The multiple adjustment holes are equidistantly located at the bottom of the first sliding shell. The two lead screws are respectively connected to two sliding blocks. A knob is fixedly connected to the top of the lead screw, which can adjust the width of the forceps. The width can be adjusted in real time according to different patients, thus enhancing adaptability.

[0010] Preferably, the connecting assembly includes two first links, which are rotatably mounted on one end of two top clamping rods, and a second link is rotatably mounted on one end of each of the first links, and the two second links are rotatably mounted on one end of each of the two bottom clamping rods.

[0011] Preferably, the blocking assembly includes two baffles, four sliding seats are symmetrically installed on the inner side of the baffles, and a locking rod is slidably installed between the two sliding seats on the same side. A spring is sleeved on the outer side of the locking rod, and a handle is fixedly installed in the middle of the locking rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are: The removable baffles on the cheek and tongue sides effectively block the cheeks and tongue, preventing them from interfering with the stamp placement and allowing the stamp to be placed more smoothly and accurately in the target position, significantly improving the convenience and accuracy of operation. The tweezers component in the middle can firmly hold the plastic wrap and other separating materials, ensuring the separation effect between the stamp and the filling resin, preventing the two from sticking together, and helping to improve the quality of the filling. The detachable baffle design makes this auxiliary tool suitable for different patients' oral conditions and different operating scenarios, meeting diverse clinical needs; at the same time, the tool has a simple structure, is easy to operate, and is easy for medical staff to master and use, thus having high clinical application value.

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0016] Please see Figure 1-4 This utility model provides an auxiliary tool for the posterior tooth resin filling stamp method, including two pressing rods 1, a shaft assembly fixedly installed at one end between the two pressing rods 1, a tweezer assembly for gripping fixedly installed at one end of the shaft assembly, an adjustment component installed inside the tweezer assembly, a connecting component rotatably installed at one end of the tweezer assembly, and a blocking component for blocking the inner cheek and tongue when engaged on the outside of the tweezer assembly.

[0017] Furthermore, the shaft assembly includes two mounting plates 2, which are respectively fixedly mounted on one end of two pressing rods 1. A rotating seat 3 is fixedly mounted on each of the two mounting plates 2. A rotating shaft 4 is rotatably mounted between the two rotating seats 3. A torsion spring 5 is mounted on the outside of the rotating shaft 4. The two ends of the torsion spring 5 are in contact with the two mounting plates 2.

[0018] Furthermore, the tweezers assembly includes a first sliding shell 6 and a second sliding shell 7. The first sliding shell 6 and the second sliding shell 7 are respectively fixedly installed at one end of the two mounting plates 2. Two sliding blocks 9 are slidably installed inside the first sliding shell 6. A top clamping rod 10 is fixedly installed at one end of each of the two sliding blocks 9. Two bottom clamping rods 8 are slidably installed inside the second sliding shell 7. A connecting seat 21 is fixedly installed at both ends of one side of each of the two bottom clamping rods 8.

[0019] Furthermore, the adjustment assembly includes multiple adjustment holes 13 and two lead screws 12. The multiple adjustment holes 13 are equidistantly located at the bottom of the first sliding shell 6. The two lead screws 12 are respectively connected to two sliding blocks 9. A knob 11 is fixedly connected to the top of the lead screw 12. The connection assembly includes two first connecting rods 14. The two first connecting rods 14 are rotatably mounted on one end of two top clamping rods 10. A second connecting rod 15 is rotatably mounted on one end of the first connecting rod 14. The two second connecting rods 15 are rotatably mounted on one end of two bottom clamping rods 8. Rotating the knob 11 in the opposite direction drives the lead screws 12. The transmission occurs inside the sliding block 9, disengaging from the currently inserted adjustment hole 13. Then, by pulling, the sliding block 9 is moved, causing the lead screw 12 to move to another adjustment hole 13. Then, by turning the knob 11 clockwise, the lead screw 12 is re-inserted into the corresponding adjustment hole 13, thereby completing the adjustment of the width between the two top clamping rods 10. Because the bottom clamping rod 8 and the top clamping rod 10 are connected by the first connecting rod 14 and the second connecting rod 15, when the top clamping rod 10 is moved and adjusted, it drives the bottom clamping rod 8 to move and adjust synchronously.

[0020] Furthermore, the blocking assembly includes two baffles 16, with four sliding seats 17 symmetrically installed on the inner side of the baffles 16. A locking rod 18 is slidably installed between two sliding seats 17 on the same side. A spring 19 is sleeved on the outer side of the locking rod 18, and a handle 20 is fixedly installed in the middle of the locking rod 18. The four locking rods 18 are slidably connected to four connecting seats 21 respectively. Pulling the handle 20 causes the locking rod 18 to slide between the corresponding two sliding seats 17, compressing the spring 19. When the handle 20 is released, the spring 19's rebound force causes the locking rod 18 to slide back to its original position. In this way, the baffles 16 can be installed or removed.

[0021] In this embodiment, the following steps are taken during use: Pulling the handle 20 compresses the spring 19, and releasing the handle 20 connects the locking rod 18 to the corresponding connecting seat 21, allowing the two baffles 16 to be installed. The tool width is then adjusted according to the patient's condition. Pressing the two pressing rods 1 opens the top clamping rod 10 and bottom clamping rod 8 via the rotating shaft 4 and torsion spring 5. The required isolation film is placed between the two top clamping rods 10 and the two bottom clamping rods 8. Releasing the two pressing rods 1 causes the torsion spring 5 to rebound, clamping and fixing the top clamping rods 10 and bottom clamping rods 8, ensuring the isolation material does not shift during operation. The two baffles 16 block the cheeks and tongue on both sides of the teeth during operation, providing ample space for the stamp and reducing interference. When the baffles 16 are not needed or for other operations, they can be removed for easy tool storage and carrying.

[0022] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
