Description

Technical Field

[0001] This utility model relates to the field of dental implant surgical tools, and in particular to a surgical tool for transpterygoid maxillary dental implantation. Background Technology

[0002] Dental implant surgery is a procedure that replaces missing teeth by implanting an artificial tooth root (usually a titanium alloy or ceramic implant) into the alveolar bone. During the procedure, the dentist first makes an incision in the gum to expose the alveolar bone, then drills a hole in the bone to insert the implant. Bone grafting or gingival restoration may be performed if necessary to ensure the implant's stability and the health of surrounding tissues. After surgery, a period of healing is required for the implant to integrate tightly with the bone tissue before the abutment and crown are installed, restoring the tooth's chewing function and aesthetics. Dental implant surgery is minimally invasive, has a fast recovery time, and effectively prevents alveolar bone atrophy, making it a commonly used method for restoring missing teeth in modern dentistry.

[0003] In existing technologies, the handle structure design is relatively simple and lacks modular or multi-functional interfaces, which makes the operation less flexible when it is necessary to change to different types or specifications of tools. This not only increases the difficulty of replacement but may also prolong the operation time and reduce work efficiency. At the same time, in precision surgery or high-requirement operations, it can easily affect the accuracy and safety of the operation. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a surgical tool for maxillary wing implant surgery, which aims to improve the problem that the existing technology has a simple handle structure design and lacks modular or multi-functional interfaces, resulting in insufficient operational flexibility when it is necessary to change to different types or specifications of tools.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A surgical tool for transpterygoid maxillary dental implantation includes two sets of tool shells, each containing two sets of soft pads. The surfaces of the soft pads are provided with multiple sets of elastic rings. Each set of elastic rings contains a handle, three sets of drill bits, three sets of bone compressors, four sets of implant carriers, three sets of parallel rods, and a measuring ruler.

[0007] By adopting the above technical solutions, a combination structure of soft pads and multiple sets of elastic rings is set inside the tool shell to achieve orderly storage and stable fixation of various surgical instruments. By installing three sets of drill bits, three sets of bone compressors, four sets of implant carriers, three sets of parallel rods and measuring rulers at the rear end of the handle, different tools can be used conveniently.

[0008] Preferably, the two sets of tool housings are rotatably connected by a hinge, and the right tool housing has two sets of positioning plates on its right side, and each of the two sets of positioning plates has a positioning strip on its upper left side, and the left tool housing has two sets of matching positioning grooves on its left side.

[0009] Preferably, the two sets of pads are respectively installed inside the tool housing by two sets of Velcro.

[0010] Preferably, the handle has a hexagonal slot at its rear end, and the three sets of bone compressors, four sets of implant carriers, three sets of parallel rods, and the front end of the measuring ruler are all equipped with matching hexagonal locking blocks.

[0011] Preferably, the diameters of the three sets of drill bits are set to 2mm, 2.2-2.8mm and 3.2mm, respectively.

[0012] Preferably, the diameters of the three sets of bone compressors are set to 2 mm, 2.8 mm and 3.2 mm, respectively.

[0013] Preferably, the three sets of parallel bars are bent at 17 degrees, 30 degrees and 45 degrees respectively.

[0014] Preferably, the surfaces of the three sets of drill bits, the three sets of bone compressors, and the measuring ruler are each provided with graduated grooves.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, by using a hexagonal slot with a handle and a hexagonal locking block, the replacement of three sets of bone compressors, four sets of implant carriers, three sets of parallel rods and measuring rulers can be quickly completed by simply aligning them with the hexagonal slot, which improves the efficiency of instrument switching during surgery. Compared with the circular interface, the hexagonal structure has a natural anti-rotation performance, and will not slip or loosen after insertion, ensuring more reliable force during operation.

[0017] 2. In this utility model, the three sets of drill bits, the three sets of bone compressors, and the measuring ruler are each provided with a graduated groove. The graduated groove can help doctors control the depth of drilling and bone compression, avoid operation that is too shallow or too deep, and ensure that the hole and the implant size are matched. The graduated groove of the measuring ruler 14 can be used to accurately measure the bone height, hole depth, or implant length requirements, thereby assisting in the selection of appropriate implant specifications.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7The present invention provides an embodiment of a surgical tool for transpterygoid maxillary dental implantation, comprising two sets of tool shells 1, two sets of soft pads 6 inside the two sets of tool shells 1, multiple sets of elastic rings 8 on the surface of the two sets of soft pads 6, and handles 9, three sets of drill bits 10, three sets of bone compressors 11, four sets of implant carriers 12, three sets of parallel rods 13 and measuring rulers 14 respectively inside the multiple sets of elastic rings 8.

[0030] Specifically, a combination structure of soft pads 6 and multiple sets of elastic rings 8 is set inside the tool housing 1 to achieve orderly storage and stable fixation of various surgical instruments. By installing three sets of drill bits 10, three sets of bone compressors 11, four sets of implant carriers 12, three sets of parallel rods 13 and measuring rulers 14 at the rear end of the handle 9, different tools can be used conveniently.

[0031] Reference Figure 2 The two sets of tool housings 1 are rotatably connected by hinges 2, and the right tool housing 1 has two sets of positioning pieces 3 on the right side, and the upper left side of each of the two sets of positioning pieces 3 is provided with positioning strips 4, and the left tool housing 1 has two sets of matching positioning grooves 5 on the left side.

[0032] Specifically, the hinge 2 facilitates the opening and closing of the tool housing 1. Then, by setting the positioning piece 3 and the positioning strip 4 into the matching positioning groove 5, the positioning piece 3 is fixed, thereby fixing the two sets of tool housings 1 and making it easy to close the tool housing 1.

[0033] Reference Figure 2 The two sets of soft pads 6 are respectively installed inside the tool housing 1 by two sets of Velcro 7;

[0034] Specifically, the Velcro 7 allows the soft pad 6 to be easily installed inside the tool housing 1.

[0035] Reference Figure 3 The handle 9 has a hexagonal slot at the rear end, and the three sets of bone squeezers 11, the four sets of implant carriers 12, the three sets of parallel rods 13 and the measuring ruler 14 are all equipped with matching hexagonal locking blocks at the front end.

[0036] Specifically, the hexagonal slots and hexagonal locking blocks enable a quick, stable, and directional connection during assembly. When replacing the three sets of bone compressors 11, four sets of implant carriers 12, three sets of parallel rods 13, and measuring ruler 14, simply aligning them with the hexagonal slots allows for rapid loading and unloading, improving the efficiency of instrument switching during surgery. Compared to circular interfaces, the hexagonal structure has a natural anti-rotation property, preventing slippage or loosening after insertion and ensuring more reliable force application during operation.

[0037] Reference Figure 4 The diameters of the three sets of drill bits were set to 2mm, 2.2-2.8mm and 3.2mm respectively;

[0038] Specifically, the smaller diameter drill bit 10 can be used to initially establish the guide hole, reducing the impact on the bone. The medium diameter drill bit 10 can gradually enlarge the hole diameter based on the initial hole, making the bone tissue more uniformly stressed and the hole enlargement process more stable. The largest diameter drill bit 10 is used for final shaping, providing a suitable hole size for implant insertion.

[0039] Reference Figure 5 The diameters of the three sets of bone compressors 11 are set to 2mm, 2.8mm and 3.2mm respectively;

[0040] Specifically, smaller diameter extruders can be used for initial entry and gentle compression of the bone wall to avoid excessive force at once that could cause bone fracture. Medium diameter extruders further expand the channel based on the initial extrusion, so that the bone tissue is evenly compacted along the hole wall. The largest diameter extruder is used for final shaping, so that the hole wall reaches the density and size that matches the implant.

[0041] Reference Figure 7 The three sets of parallel bars 13 are respectively set to bend at 17 degrees, 30 degrees and 45 degrees;

[0042] Specifically, due to individual differences in the spatial shape of the maxilla, pterygoid process, and related channels, doctors need to flexibly adjust the parallelism check according to the bone surface angle, channel inclination, and final implant direction during operation. Three parallel rods 13 with commonly used bending angles are set up to provide more accurate references at each stage from initial positioning and direction calibration to final confirmation. This allows doctors to quickly select the parallel rod 13 that best matches the surgical channel, reduce repeated adjustments, and achieve higher implantation accuracy and surgical safety.

[0043] Reference Figure 4 , Figure 5 and Figure 7 The surfaces of the three sets of drill bits 10, the three sets of bone compressors 11, and the measuring ruler 14 are respectively provided with graduated grooves;

[0044] Specifically, the graduated grooves of the drill bit 10 and the bone compressor 11 help doctors control the depth of drilling and bone compression, avoiding operation that is too shallow or too deep, and ensuring that the hole size matches the implant size. The graduated grooves of the measuring ruler 14 can be used to accurately measure the bone height, hole depth, or implant length requirements.

[0045] Working principle: Open the two sets of tool housings 1 through the hinge 2, then take out the handle 9. As needed, install three sets of drill bits 10, three sets of bone compressors 11, four sets of implant carriers 12, and three sets of parallel rods 13 or measuring rulers 14 at the rear end of the handle 9, and then operate the handle 9 to treat the patient.

[0046] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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 utility model should be included within the protection scope of the present utility model.
