Description

Technical Field

[0001] The invention relates to the technical field of dental tools, and in particular to a dental implant carrying device and a matching implant tool assembly. Background Art

[0002] The surface of dental implants has been specially treated. In order to prevent damage to the surface of dental implants during packaging and movement, and to facilitate doctors to take out the dental implants from the packaging and put them into the implant cavity for implantation, dental implant manufacturers generally make carrying devices to fix the dental implants to the packaging.

[0003] The implantation tool is used to connect a carrying device and a manual torque wrench (or a dental handpiece), and to transfer the dental implant connected to the carrying device to the implantation site for implantation. In this case, if there is a mismatch between the implantation tool and the carrying device, or between the carrying device and the implant, it may fall off the implantation tool or the carrying device before reaching the implantation cavity. If the detached object is swallowed or inhaled, it may cause serious harm to the patient's health. In addition, the implantation tool and the carrying device, or between the carrying device and the dental implant, should not fit too tightly, otherwise it will increase the difficulty of removing the implantation tool or the carrying device after the dental implant is implanted, and the dental implant may even be removed together, resulting in implantation failure. Therefore, both the carrying device and the implantation tool are very important in the dental implantation process.

[0004] Most existing carrying devices are composed of two or more parts, such as a carrying body and a carrying body screw. Due to the small size of the parts, they need to be processed by precision equipment, resulting in high production costs. At the same time, after the implantation surgery is completed, the carrying device needs to be disassembled to unload these parts, which increases the operation time and reduces the convenience.

[0005] Some manufacturers' carrying devices are integrated, and their insertion tools (equivalent to the so-called carrying body in the industry) are complex in shape and require special processing equipment such as a processing center for processing, which has high processing costs. The parts of the insertion tool used to clamp the dental implant are made of metal. In order to prevent the metal from deforming and failing to clamp, causing the dental implant to fall off, or clamping too tightly, causing the insertion tool to be difficult to remove, a material with good elasticity must be selected; in addition, because the insertion tool needs to be used with a dental handpiece or a torque wrench for implantation later, it requires a high torsion resistance, so a material with a high hardness is required; in other words, the material needs to have both good elasticity and high hardness (such as titanium alloy, etc.), which increases the material cost. Summary of the invention

[0006] The technical solution aims to provide a dental implant carrying device to solve one or more technical problems existing in the prior art and at least provide a beneficial choice or create conditions.

[0007] A dental implant carrying device, comprising:

[0008] The carrying body is a columnar component, one end of which is provided with an implant tool combination section, and the other end is provided with a dental implant combination section, the implant tool combination section is adapted to the external implant tool interface, and the dental implant combination section is adapted to the external dental implant base interface;

[0009] The connecting body is a columnar member, coaxial with the carrying body, and includes a connecting rod and a joint, one end of the connecting rod is connected to the dental implant combining section, and the other end of the connecting rod is connected to the joint, and the diameter of the connecting rod is smaller than the diameter of the joint;

[0010] The carrier is a medical metal component, the connector is a non-toxic polymer material component, and the non-toxic polymer material is selected from polyetheretherketone, polyphenylene sulfone resin, polyethersulfone resin, polypropylene, and polycarbonate.

[0011] The existing carrying device is designed as an integrated molding, so its manufacturing material needs to have both good elasticity and high hardness, which leads to high cost. The dental implant carrying device provided by the technical solution is composed of a carrying body and a connecting body made of different materials. The connecting body is made of a material with good elasticity, while the carrying body is made of a material with high hardness, so that the assembled dental implant carrying device has both elasticity and hardness, and the overall material cost and processing cost are much lower than those of the existing carrying device.

[0012] Furthermore, a connector mounting hole is provided in the carrying body, and the connector mounting hole extends from the end surface of the dental implant coupling section into the carrying body along the axis of the carrying body, and the connector is fixedly connected to the connector mounting hole. Since the dental implant carrying device needs to drive the dental implant to rotate under the drive of a torque wrench or a dental handpiece, the carrying body and the connector are coaxial, which makes it easier to achieve force transmission.

[0013] Furthermore, the connector mounting hole includes a first hole segment and a second hole segment in sequence, the diameter of the first hole segment is smaller than that of the second hole segment, the first hole segment is close to the end surface of the dental implant coupling segment, the connector also includes a rod tail, the rod tail is located in the second hole segment, and the connecting rod passes through the first hole segment. A step structure is formed in the connector mounting hole by the first hole segment and the second hole segment of different diameters. The rod tail and the connecting rod of the connector are limited by the step structure to prevent the connector from falling out of the carrying body.

[0014] Furthermore, the connector mounting hole passes through the carrier, and the connector mounting hole also includes a third hole segment, the third hole segment extends from the end surface of the implant tool combination segment to connect with the second hole segment, and the diameter of the third hole segment is greater than or equal to the second hole segment. The connector mounting hole that passes through the carrier facilitates the assembly of the carrier and the connector on the one hand, and also allows the connection between the carrier and the internal implant tool on the other hand.

[0015] Furthermore, the rod tail is interference fit with the second hole segment. During assembly, a cylinder and a tool can be used to press the connector from the hole of the third hole segment into the connector mounting hole. Since the connector has good elasticity, interference fit is easy to achieve and can also have a certain anti-rotation effect.

[0016] Furthermore, the inner wall of the third hole section has at least one inner anti-rotation plane, and the inner anti-rotation plane is adapted to the internal implantation tool, so that the internal implantation tool can drive the dental implant carrying device to rotate synchronously.

[0017] Furthermore, the surface of the implant tool coupling section has at least one external anti-rotation plane, and the external implant tool is adapted to the external implant tool so that the external implant tool can drive the dental implant carrying device to rotate synchronously.

[0018] On the one hand, the present application provides an internal implant tool, including a cylindrical first body, the first body including a first drive coupling portion and a first implant tool interface, the first drive coupling portion is adapted to the connection port of an external torque wrench or a dental mobile phone, and the first implant tool interface is adapted to the third hole section of the above-mentioned dental implant carrying device.

[0019] On the other hand, the present application also provides an external implantation tool, comprising a cylindrical second body, the second body comprising a second drive coupling portion and a second implantation tool interface, the second drive coupling portion being adapted to the connection port of an external torque wrench or dental mobile phone, and the second implantation tool interface being adapted to the implantation tool coupling section of the above-mentioned dental implant carrying device.

[0020] On the other hand, the present application further provides a tool assembly, which includes the aforementioned dental implant carrying device, an internal implant tool and an external implant tool.

[0021] The present invention has the following advantages: the dental implant carrying device is composed of a carrying body and a connecting body made of different materials. The connecting body is made of a material with good elasticity, while the carrying body is made of a material with high hardness, so that the assembled dental implant carrying device has both elasticity and hardness, and the overall material cost and processing cost are much lower than the existing carrying device. Since the connecting body is made of non-toxic polymer material, it can be mass-produced by injection molding and other methods; and the carrying body is a medical metal component, which can be mass-produced by precision casting, CNC machine tool turning and other methods. The two only need to be simply assembled before use, and the production efficiency is much higher than the existing integrated carrying device. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] Embodiment 1, a dental implant carrying device, such as Figure 1 As shown, including:

The implant tool coupling section 111 is adapted to the external implant tool interface. The dental implant coupling section 112 is adapted to the external dental implant base interface. A connector mounting hole is provided in the carrier 110, and the connector mounting hole extends from the end face of the dental implant coupling section 112 along the axis of the carrier 110 into the carrier 110, and the connector mounting hole includes a first hole section 113 and a second hole section 114 in sequence, and the diameter of the first hole section 113 is smaller than that of the second hole section 114, and the first hole section 113 is close to the end face of the dental implant coupling section 112.

[0034] The connecting body 120 is a columnar member, coaxial with the carrying body 110, and includes a joint 121, a connecting rod 122 and a rod tail 123 in sequence. The rod tail 123 is located in the second hole section 114, and the connecting rod 122 passes through the first hole section 113, one end of which is connected to the rod tail 123, and the other end is connected to the joint 121 located outside the carrying body 110. The diameter of the joint 121 is larger than the diameter of the connecting rod 122, and the diameter of the joint 121 is slightly larger than the threaded inner hole of the dental implant. The joint 121 is also provided with an "I"-shaped groove so that it can be retracted when the dental implant is inserted. The edge of the end of the joint 121 is provided with a chamfer to help it be inserted into the dental implant more easily.

[0035] The carrier 110 is a medical stainless steel component, and the connector 120 is a polyetheretherketone component. The connector 120 is obtained by adding a mold outside the carrier 110 and directly injecting the connector mounting hole and the mold, thereby forming the connector 120 in one piece.

[0036] Embodiment 2, a dental implant carrying device, such as Figure 2 and 3 As shown, including:

[0037] like Figure 3 As shown, the carrier 210 is a columnar member, one end of which is provided with an implant tool combination section 211, and the other end is provided with a dental implant combination section 212. The implant tool combination section 211 is adapted to the external implant tool interface; the dental implant combination section 212 is adapted to the external dental implant base interface. A connector mounting hole 213 is provided in the carrier 210, and the connector mounting hole 213 passes through the carrier 210 along the axis of the carrier 210. The connector mounting hole 213 includes a first hole section 214, a second hole section 215 and a third hole section 216 in sequence. The diameter of the first hole section 214 is smaller than that of the second hole section 215. The first hole section 214 is close to the end face of the dental implant combination section 212. The third hole section 216 extends from the end face of the implant tool combination section 211 to connect with the second hole section 215. The diameter of the third hole section 216 is greater than or equal to the second hole section 215. The inner wall of the third hole section 216 has an inner hexagonal anti-rotation structure composed of six inner anti-rotation planes 217, and the surface of the implant tool combination section 211 has an outer hexagonal anti-rotation structure composed of six outer anti-rotation planes 218. The surface of the dental implant combination section 212 is provided with an anti-rotation structure adapted to the inner hexagonal hole of the dental implant.

[0038] like Figure 2 As shown, the connecting body 220 is a columnar member, coaxial with the carrying body 210, and includes a joint 221, a connecting rod 222 and a rod tail 223 in sequence. One end of the connecting rod 222 is connected to the rod tail 223, and the other end is connected to the joint 221. The diameter of the rod tail 223 is slightly larger than the inner diameter of the second hole section 215. The diameter of the connecting rod 222 is less than or equal to the inner diameter of the first hole section 214. The diameter of the joint 221 is larger than the diameter of the connecting rod 222, and the diameter of the joint 221 is slightly larger than the threaded inner hole of the dental implant. The joint 221 is also provided with a "cross"-shaped slot so that it can be retracted when the dental implant is inserted. The edge of the end of the joint 221 is provided with a chamfer to help it be inserted into the dental implant more easily.

[0039] The carrier is a titanium alloy component, and the connector is a polyetheretherketone component. The rod tail 223 is interference fit with the second hole section 215. During assembly, a cylinder and a tool can be used to press the connector 220 from the orifice of the third hole section 216 into the connector mounting hole 213. Since the connector 220 has good elasticity, interference fit is easy to achieve, and it can also have a certain anti-rotation effect. In the process of the connector 221 passing through the first hole section 214, its "cross"-shaped slot allows the connector 221 to be greatly compressed, so that it can pass smoothly. Although the carrier described in this embodiment is made of a relatively expensive titanium alloy, its structure is lighter (hollow and omits the part for inserting the implant) and simpler (reducing a large number of step structures and slots) than the traditional integrated carrier, so the material cost and processing cost are still lower than traditional products.
