Description

Technical Field

[0001] The invention belongs to the technical field of dental implantation, and in particular relates to a novel dental implantation guide adapted to a digital guide plate. Background Art

[0002] Dental implant surgery includes the preparation of implant cavities and the implantation of implants. During the cavity preparation process, a digital static guide can be used in conjunction with a collar of the corresponding size or a pressure plate in the surgical tool box to guide the drill. At this stage, the drill is rigidly constrained by the collar or pressure plate, which helps to achieve accurate cavity preparation. During the implantation process, in order to protect the implant surface, the implant cannot have any contact with the inner wall of the guide components such as the collar or catheter. Only when the adapter connected to the top of the implant contacts the inner wall of the guide component, the guide begins to guide the implantation process. However, almost all implant systems have inherent, non-guiding structures, including the implant and the carrier above it. When the length of the "non-guiding structure" is greater than the distance that the guide generates a guiding effect, the guide cannot provide effective guidance in the initial stage of implantation. This problem is particularly evident in implant surgery in the anterior region. In addition, in order to ensure that the implant obtains sufficient initial stability, the diameter of the cavity preparation is usually smaller than the diameter of the implant. At this time, insufficient guidance or even lack of guidance will more easily cause the adapter to tilt in the guide, causing implant implantation deviation. Moreover, a large tilt may prevent the adapter from passing through the guide component smoothly, affecting further surgery. At this time, the guide plate can only be removed and the implant can be performed manually based on experience. The implantation accuracy will be even more uncontrollable, which goes against the original intention of using the guide plate. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a new dental implant guide adapted to the digital guide plate in view of the deficiencies of the above-mentioned prior art, which can extend the guiding height of the implant guide plate, thereby providing effective guiding effect in the initial stage of implantation, thereby realizing precise guiding of implant implantation.

[0004] The technical solution adopted by the present invention is: a new type of dental implant guide adapted for a digital guide plate, comprising a scissor-shaped guide body composed of two guide rods, a gripping ring being formed on the outer side of one end of the guide rod, and a semicircular guide gasket being provided on the inner wall of the other end, the outer arc top surface of the guide gasket being fixedly connected to the inner wall of the guide rod, a sliding piece matching it being provided inside the guide gasket, a linkage mechanism being installed in a section of the guide rod close to the guide gasket, a control switch of the linkage mechanism being located on the outer wall of the guide rod, a driven mechanism of the linkage mechanism being connected to the sliding piece so that the sliding piece can be vertically lifted and lowered in the guide gasket, and the inner wall of the guide gasket can also be detachably connected with an adapter piece matching the guide gasket, and when the guide body is closed and clamped, the two guide gaskets, the two sliding pieces and the two adapter pieces are all spliced ​​in a circular ring shape.

[0005] Preferably, the linkage mechanism includes a synchronous belt, a connecting shaft, a driven gear, a rack and two synchronous wheels. The two synchronous wheels are fixed in the guide rod along the length direction of the guide rod. The synchronous belt is mounted on the synchronous wheel. A slider is provided on the side of the synchronous belt away from the guide gasket. A slide groove is provided along the length direction of the guide rod at a position corresponding to the slider on the guide rod. The slider is located in the slide groove, and one side of the slider is fixedly connected to the synchronous belt. The driven gear is meshed with the rack and are both located in the guide gasket. The rack is provided along the height direction of the guide gasket, and one side of the rack is fixedly connected to the slide. The driven gear is aligned with the synchronous wheel close to the guide gasket, and is connected to the synchronous wheel close to the guide gasket through a connecting shaft.

[0006] Preferably, a stopper is provided on the inner wall of the guide rod close to the gripping ring, and the guide body is locked when two stopper plates on the guide body engage with each other.

[0007] The beneficial effects of the present invention are:

[0008] (1) The guide body is used in conjunction with the implant guide plate, so that the guide gasket of the guide body is matched with the matching plate to match the implant channel of the implant guide plate, thereby effectively extending the guiding height of the implant guide plate to the adapter, and making the implantation position more accurate through guided implantation;

[0009] (2) The adapter and the guide gasket are detachably connected, and adapters of different sizes can be replaced according to different implant guides and different adapters, which has good universality;

[0010] (3) A liftable slide is provided inside the guide gasket to facilitate the connection or disconnection between the guide body and the planting guide plate at any time;

[0011] (4) A stopper is provided, and the guide body can be locked by the engagement of the stopper, so that the guide body has a certain resistance to lateral force;

[0012] (5) The linkage mechanism adopts synchronous belt, synchronous wheel, rack and gear, which ensures smooth transmission and improves the stability of guidance.

[0013] The present invention is used in conjunction with a planting guide plate, which can effectively increase the guiding height of the planting guide plate, ensure the guiding accuracy in the initial stage of planting, and thus reduce the error of implant placement.

[0021] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Example

[0022] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the novel dental implant guide adapted for the digital guide provided in this embodiment comprises two guide rods 1, which are cross-arranged and connected by a pin at the intersection, and the outer sides of the ends of the two guide rods 1 are respectively formed with gripping rings 2, and the head ends of the two guide rods 1 are bent inwardly to form mutually parallel clamping parts, and guide gaskets 3 are provided on the inner sides of the head ends, so that the two guide rods 1 form a scissor-shaped guide body;

[0023] A stopper 6 is symmetrically formed on one side of the ends of the two guide rods 1 away from the grip ring 2. Stopper teeth are evenly distributed on the surface of one stopper 6, and stopper teeth are evenly distributed on the bottom surface of the other stopper 6. The two stopper plates 6 cooperate with each other to lock the ends of the guide rods 1, that is, the two guide rods 1 are fixed;

[0024] Synchronous wheels 502 are respectively installed at both ends of the clamping part in the guide rod 1. One side of the synchronous wheel 502 is connected to the inner wall of the guide rod 1 through a rotating shaft. The two synchronous wheels 502 are set with synchronous belts 501 matching them. A slide groove 507 arranged along the length direction of the guide rod 1 is opened at the outer side of the guide rod 1 corresponding to the synchronous belt 501. A strip groove running through the slide groove 507 is opened in the slide groove 507. A slider 506 is connected to the side of the synchronous belt 501 close to the slide groove 507. The slider 506 is H-shaped. One end of the slider 506 is fixedly connected to the synchronous belt 501, and the other end is located in the slide groove 507 and slidably cooperates with the slide groove 507. The middle part of the slider 506 is placed in the strip groove and cooperates with the gap of the strip groove. When the slider 506 slides in the slide groove 507, the slider 506 drives the synchronous belt 501 to move, thereby driving the synchronous wheel 502 to rotate;

[0025] The synchronous wheel 502 near the head end of the guide rod 1 corresponds to the position of the guide gasket 3, and a driven gear 504 is installed at the position corresponding to the synchronous wheel 502 inside the guide gasket 3. One side of the driven gear 504 is connected to the inner wall of the guide gasket 3 through a rotating shaft, and the other side is connected to the synchronous wheel 502 through a connecting shaft 503. A vertically arranged rack 505 is meshed on the driven gear 504, and a lifting groove matching the rack 505 is vertically opened in the middle of the guide gasket 3. The rack 505 is placed in the lifting groove. The lifting groove opens at a position corresponding to the driven gear 504 for the driven gear 504 to mesh with the rack 505. A slide 4 is fixedly connected to the side of the rack 505 away from the guide rod 1, and the slide 4 is connected to the guide gasket The shape of the plate 3 is matched, and it can be lifted up and down in the guide gasket 3 with the rack 505. At the same time, the length of the rack 505 is moderate. When the slider 506 drives the synchronous belt 501 to move, the synchronous wheel 502 drives the driven gear 504 to rotate, and the driven gear 504 drives the rack 505 to lift and lower. When the slider 506 is located at the end of one end of the guide gasket in the slide groove 507, the rack 505 is in the lower limit position, the bottom end of the rack 505 is flush with the bottom of the guide gasket 3, and the slide 4 is in an extended state; when the slider 506 is located at one end of the grip ring in the slide groove 507, the rack 505 is in the upper limit position, that is, the rack 505 is in the initial position, and the slide 4 is completely retracted into the guide gasket 3;

[0026] The inner side of the guide gasket 3 is detachably connected with an adapter sheet 7. For different adapters, adapter sheets 7 of different sizes can be replaced to match different adapters, which has wide applicability;

[0027] When the two guide rods 1 move relative to each other and are closed and clamped, the two guide gaskets 3 and the two adapter plates 7 are spliced ​​into a circular ring. If the two slides 4 are in an extended state, the two slides 4 are also spliced ​​into a circular ring. At this time, the two guide rods 1 can be locked with each other through the cooperation of the two stop plates 6, thereby maintaining the circular ring formed by the guide gaskets 3, the adapter plates 7 and the slide plates 4; and the inner diameter of the circular ring spliced ​​by the adapter plates 7 matches the outer diameter of the adapter, and the outer diameter of the circular ring spliced ​​by the slide plates matches the diameter of the implantation guide implantation channel, thereby achieving guidance in coordination with the implantation guide.

[0028] When in use, select the adapter piece 7 that matches the adapter, and install the adapter piece 7 on the inner side of the guide gasket 3, so that after the adapter piece 7 is spliced ​​into a ring, it matches the outer diameter of the adapter, which is convenient for guiding the adapter, and the outer diameter of the ring spliced ​​by the slide 4 matches the inner diameter of the implantation channel, that is, the slide 4 ring is in contact with the inner wall of the implantation channel, and can be raised and lowered on the surface of the inner wall of the implantation channel;

[0029] The two guide rods 1 are controlled to close by the holding ring 2, so that the guide gasket 3, the slide 4 and the adapter 7 are spliced ​​into a ring, and then the guide rod 1 is locked by the stopper 6. At this time, the slide 4 is located in the guide gasket 3. The doctor extends the guide body into the patient's mouth and places it on the implant guide plate, so that the spliced ​​ring of the guide gasket 3 is located at the implantation channel and aligned with the implantation channel, and then pushes the slider 506, so that the slider 506 drives the synchronous belt 501 to move, so that the synchronous wheel 502 rotates, and the synchronous wheel 502 rotates to drive the driven gear 504 to rotate, and the driven gear 504 rotates to cause the rack 505 meshing with it to move downward, and the slide 4 is fixedly connected to the rack 505, so that the slide 4 moves with the rack 505 descends, that is, the slide 4 descends and extends into the implantation channel and fits with the inner wall of the implantation channel. The slides 506 of the two guide rods 1 are controlled separately, so as to establish a connection or disconnection relationship with the implantation channel of the implantation guide at any time. When the two slides 506 are both descended and raised into the implantation channel, the relationship between the guide body and the implantation guide is established, and the adapter is connected to the implant. The guiding effect is realized under the joint constraints of the implantation channel and the ring of the adapter 7, and the guiding height is effectively extended. When the implantation mobile phone is about to reach the top of the guide gasket 3, push back the slide 506, raise the slide 4, release the stopper 6, and then the guide body can be removed, and then the implantation guide continues to guide the implantation to the designed depth.

[0030] The above description is only a preferred implementation manner of the present invention, but the protection scope of the present invention is not limited thereto, and any modification and replacement based on the technical solution and inventive concept provided by the present invention should be included in the protection scope of the present invention.
