Description

Joint structure of dental driver

[0001] The present invention relates to a combination structure of a dental driver for combining a dental driver for implant surgery.

[0002] Implant surgery is a dental treatment that restores the function of natural teeth by implanting an artificial tooth made of biocompatible material in a missing tooth area or when a tooth has been extracted. It also involves screwing an abutment onto the implanted implant and then fixing a prosthesis onto the abutment.

[0003] When performing an implant procedure, the fixture is placed into the alveolar bone and then a cover screw or healing abutment is tightened on top of it to connect it. A driver is used when tightening the cover screw or healing abutment.

[0004] This type of driver is connected by tightening the cover screw or healing abutment while the operator holds the driver in his / her hand and rotates it. However, since dental treatment is performed with the patient's mouth open, it is not only inconvenient to hold the driver with a gloved hand while the mouth is open, but there are also cases where a serious medical accident occurs in which the driver falls into the patient's mouth if the operator accidentally drops the driver from his / her hand.

[0005] To compensate for this, there are cases where a micro hole is formed in the driver and a thread is connected to it, but in this case, there is the inconvenience of having to connect the thread to the driver every time, and as the thread rotates along with the driver, the thread inevitably winds around the driver, which is inconvenient.

[0006] The present invention has been devised to solve the above-described conventional problems, and aims to provide a combined structure of a dental screwdriver that can maximize the safety of a dental procedure by preventing the screwdriver from moving into the patient's mouth when fastening a screw to fix an abutment to a fixture in the oral cavity, and that can store the screwdriver without loss as much as possible by combining it with a separate dental tool after the procedure is completed.

[0007] In addition, another object of the present invention is to provide a joint structure of a dental driver that can prevent the connection part from twisting during treatment by providing a rotating ring that can rotate relatively to the body of the dental driver and connecting a connection part to the rotating ring.

[0008] According to one aspect of the present invention, a joint structure between a dental driver and a dental tool for implant surgery is provided, wherein the dental driver is detachably coupled to the dental tool, and a connecting portion having a predetermined length or longer is provided between the dental tool and the dental driver so that the dental driver remains connected to the dental tool even when the dental driver is detached from the dental tool.

[0009] According to another aspect of the present invention, a joint structure between a dental driver and a dental tool for implant surgery is provided, wherein the dental driver is detachably coupled to a tubular body, the tubular body is detachably coupled to the dental tool, and a connecting portion having a predetermined length or longer is provided between the tubular body and the dental driver so that the dental driver remains connected to the tubular body even when the dental driver is detached from the tubular body.

[0010] The above connecting part may include a chain made of stainless steel.

[0011] The above connecting part may be formed in the form of a wire made of metal or plastic material.

[0012] The connecting portion of the dental tool to which the dental driver is connected may be formed in a tubular shape, and the connecting portion may include a stainless steel spring, one end of which is fixed to the inside of the dental tool; and a stainless steel chain connecting the other end of the spring and the dental driver.

[0013] The above dental driver can be screw-coupled to the above dental tool.

[0014] The connecting portion of the tubular body to which the dental driver is connected may be formed in a tubular shape, and the connecting portion may include a stainless steel spring, one end of which is fixed to the inside of the tubular body; and a stainless steel chain that connects the other end of the spring and the dental driver.

[0015] The above dental driver can be screw-coupled to the body.

[0016] The above dental driver includes a body and a tip, and the body may be provided with a rotating ring that is rotatable relative to the body and to which an end of the connecting portion is connected.

[0017] The above dental tool may be a dental mirror.

[0018] According to the joint structure of the dental driver of the present invention described above, by providing a connecting portion of a certain length or longer between the dental tool and the dental driver, or between the body and the dental driver, the screw driver is prevented from going into the patient's mouth when tightening the screw to fix the abutment to the fixture in the oral cavity, thereby maximizing the stability of the dental procedure.

[0019] In addition, by allowing the dental screwdriver to be detachably attached to the dental tool or tube body, the screwdriver after the procedure is completed can be stored attached to the object without having to be stored separately, thereby reducing the risk of loss.

[0020] In addition, by providing a rotating ring that can rotate relative to the body of the dental driver and connecting a connecting part to the rotating ring, the phenomenon of the connecting part being twisted during treatment can be prevented.

[0028] Hereinafter, embodiments of the present invention will be described in more detail with reference to the attached drawings. However, the present invention is not limited to the embodiments disclosed below, but may be implemented in various different forms. These embodiments are provided solely to ensure complete disclosure of the present invention and to fully inform those skilled in the art of the scope of the invention. Like reference numerals throughout the drawings denote like elements.

[0029] The coupling structure of the dental driver according to a preferred embodiment of the present invention can maximize the stability of dental treatment by preventing the screwdriver from moving into the patient's mouth when fastening the screw to fix the abutment to the fixture in the oral cavity, and can store the screwdriver without loss as much as possible by coupling it to a separate dental tool after the treatment is completed.

[0030] Hereinafter, the present invention will be described in detail with reference to various embodiments.

[0031] As shown in FIGS. 1 and 2, the coupling structure of the dental driver according to the first embodiment of the present invention is a coupling structure between a dental driver (100) for implant surgery and a dental tool (200), specifically, a part of which is inserted into an abutment (10) and the remaining part is screw-connected to a fixture (20), and a screw (30) for coupling the abutment (10) and the fixture (20) is fastened to a coupling structure for coupling the dental driver (100) to another object.

[0032] In an embodiment of the present invention, a dental driver (100) is detachably coupled to a dental tool (200). Here, the dental tool (200) may be used in various ways for dental procedures, but for convenience of illustration, it is applied in the related drawings as a dental mirror, i.e., a dental mirror having a mirror at one end.

[0033] The present invention is structured such that a dental driver (100) is coupled to a dental tool (200). Since the dental driver (100) can be coupled to the dental tool (200) and stored after the procedure is completed, the dental driver (100), which is relatively smaller in size than the dental tool (200), can be prevented from being lost as much as possible.

[0034] As shown in FIG. 2, in an embodiment of the present invention, a connecting portion (300) having a predetermined length or longer is provided between a dental tool (200) and a dental driver (100) so that even if the dental driver (100) is detached (separated) from the dental tool (200), the dental driver (100) remains connected to the dental tool (200).

[0035] That is, the screw (30) fastening operation for fixing the abutment (10) is performed while the dental driver (100) is always connected to the dental tool (200) through the connecting part (300), and the practitioner rotates the dental driver (100).

[0036] During this process, there may be frequent cases where the operator drops the dental driver (100) from his / her hand, but in the present invention, since the dental driver (100) and the dental tool (200) are always connected through the connection part (300), even if a situation occurs where the dental driver (100) is dropped from his / her hand, the dental driver (100) does not enter the patient's oral cavity.

[0037] That is, since the connecting part (300) supports the dental driver (100), medical malpractice does not occur.

[0038] In an embodiment of the present invention, the dental driver (100), the dental tool (200), and the connecting part (300) are preferably made of a non-corrosive material for the safety of the patient, and may be made of stainless steel, for example.

[0039] Additionally, the connecting member (300) may include a chain made of stainless steel, but may also be formed in various other forms. When formed as a chain, the dental driver (100) can be more stably connected to the dental tool (200), thereby more reliably preventing the dental driver from becoming detached and falling into the patient's oral cavity.

[0040] Additionally, the connecting portion (300) may be formed in the form of a wire made of metal or plastic. In the case of a wire, it may be formed in the form of a plurality of strands twisted together, or may be formed as a single wire having a diameter greater than a certain diameter.

[0041] In an embodiment of the present invention, the connecting portion (300) is formed in a bendable form so as to be freely folded or unfolded.

[0042] Regarding the detachable coupling structure between the dental driver and the dental tool, as illustrated in Fig. 2, the coupling portion of the dental tool (200) to which the dental driver (100) is coupled is formed in a tubular shape. That is, the dental tool (200) includes a mirror (210) and a handle (220) having one end connected to the mirror so that the operator can hold it by hand and having an inner hollow structure, and the dental driver (100) is detachably coupled to the other end of the handle.

[0043] In an embodiment of the present invention, as illustrated in FIG. 3, the connecting portion (300) includes a stainless steel spring (310) one end of which is fixed to the inside of the handle of the dental tool (200), and a stainless steel chain (320) connecting the other end of the spring (310) and the dental driver (100). However, the present invention is not limited thereto, and the connecting portion (300) may be formed entirely in a chain structure.

[0044] Additionally, the dental driver (100) can be screw-connected to the other end of the handle of the dental tool (200).

[0045] To this end, as illustrated in FIG. 4, the dental driver (100) includes a body (110) and a tip (120), and screw threads (130) are formed on the outer surface of the dental driver (100), that is, the outer surface of the body (110) and the inner surface of the handle, respectively, to correspond to each other. That is, as described above, when storing after the completion of the procedure, the dental driver (100) can be stored while being connected to the dental tool (200) through screw connection, thereby reducing the risk of loss.

[0046] In addition, when the operator releases the screw connection of the dental driver (100) from the handle (220) of the dental tool (200) for the procedure, the moment the screw connection is released, the dental driver (100) elastically moves outward from the handle (220) by the elastic restoring force of the spring (310), so that the operator can more conveniently separate and use the dental driver (100) from the dental tool (200).

[0047] In an embodiment of the present invention, the dental driver (100) may be detachably coupled to the handle in various structures, such as a magnetic structure, a one-touch push structure, or a structure that can be detached through a one-touch push, in addition to the screw connection described above. In the case of the one-touch push structure, when the dental driver (100) is coupled to the end of the handle (220), the dental driver becomes detachable when the user pushes the dental driver once in the longitudinal direction of the handle, and is coupled to the handle when the user pushes it once more.

[0048] In an embodiment of the present invention, a magnet may be provided on at least one of the dental driver (100) and the handle. In addition, the dental driver (100) may be provided with an elastically deformable hook, and the handle may be provided with a hooking groove for engaging the hooking groove. The user may deform the hooking groove to a certain degree to separate the dental driver from the handle, and vice versa.

[0049] Here, the end of the connecting portion (300) can be directly fixed to the inner surface of the handle (220), or alternatively, it can be fixed to a separate fixing plate (not shown) provided on the inner surface of the handle.

[0050] Meanwhile, during the procedure, the practitioner rotates the dental driver (100) while the dental driver (100) is connected to the dental tool (200) through the connecting portion (300) to fasten the screw (30). At this time, the connecting portion (300) may become twisted. This twisting of the connecting portion may cause the practitioner to feel uncomfortable and reduce the accuracy of the procedure.

[0051] To prevent the occurrence of such problems, as illustrated in FIG. 4, the body (110) of the dental driver (100) may be provided with a rotating ring (140) that is rotatable relative to the body (110) and to which the end of the connecting portion (300) is connected.

[0052] The body (110) is provided with an installation groove that is concavely sunken in the circumferential direction, and the rotary ring (140) is rotatably mounted within the installation groove.

[0053] Accordingly, even if the operator holds the dental driver (100) by hand and rotates it to fasten the screw (30), the rotation ring (140) does not rotate, and thus the twisting phenomenon of the connecting part (300) does not occur. Here, the rotation ring (140), like the body (110), may be made of a non-corrosive material, for example, stainless steel.

[0054] In an embodiment of the present invention, as shown in FIG. 4, a slit groove (230) is formed at the end of the handle (220) of the dental tool (200) to which the dental driver (100) is screwed to prevent the dental driver (100) from being smoothly connected to the handle (220) by the connecting portion (300) connected to the rotating ring (140).

[0055] The slit groove (230) is formed concavely so that one side is open to the outside at the end of the handle (220), and the connecting portion (300) connected to the rotating ring (140) can enter the inside of the handle (220) through the slit groove (230).

[0056]

[0057] Hereinafter, the coupling structure of a dental driver according to the second embodiment of the present invention will be described. A repeated description of the same configuration as the first embodiment will be omitted, and it will be noted in advance that parts indicated in the drawings but not specifically described below are the same as the first embodiment.

[0058] As illustrated in FIGS. 5 to 7, the coupling structure of the dental driver according to the second embodiment of the present invention is a coupling structure between a dental driver (100) for implant surgery and a dental tool (200), in which the dental driver (100) is detachably coupled to a tube body (400) and the tube body (400) is detachably coupled to a dental tool (200).

[0059] The body part (400) is formed as a tubular structure with an empty space formed on the inside, and one end of which is connected to the handle (220) end of a dental tool (200) through a simple insertion or screw-joining structure and has a closed structure, and the other end of which has a structure that is open to the outside, and to which a dental driver (100) is screw-joined. A concave groove (410) is formed at one end of the body part (400) so that a certain portion of the handle (220) can be inserted.

[0060] When a dental driver (100) is to be used for a procedure, the practitioner can separate the tube body (400) from the dental tool (200) and then separate the dental driver (100) from the tube body (400) for use.

[0061] As shown in Fig. 7, a slit groove (see Fig. 4) is formed in the body (400) to prevent twisting of the connecting portion (300) connected to the rotating ring (140) coupled to the body (110) of the dental driver (100) as described above.

[0062] As shown in FIGS. 5 to 7, in an embodiment of the present invention, a connecting portion (300) of a certain length or longer is provided between the tube body (400) and the dental driver (100) so that even if the dental driver (100) is detached (separated) from the tube body (400), the dental driver (100) remains connected to the tube body (400).

[0063] In an embodiment of the present invention, the connecting portion (300) includes a stainless steel spring (310) of which one end is fixed to the inside of the body (400), and a stainless steel chain (320) that connects the other end of the spring (310) and the dental driver (100). However, this is not limited thereto, and, similarly to the first embodiment, the connecting portion (300) may be formed entirely in a chain structure.

[0064] While the present invention has been illustrated and described with reference to preferred embodiments intended to illustrate the principles of the invention, it is not intended to be limited to the exact configuration and operation described herein. Rather, those skilled in the art will readily appreciate that numerous modifications and variations are possible without departing from the spirit and scope of the appended claims.

[0065] The present invention has industrial applicability in that it can maximize the safety of dental treatment by preventing the screwdriver from moving into the patient's mouth when screwing in an abutment to a fixture in the oral cavity, and can store the screwdriver without loss as much as possible by combining it with a separate dental tool after the treatment is completed.
