Planting guide

Abstract

The application provides a planting guide plate, which comprises a fixing part and a guide ring. The guide ring is arranged in the fixing part, the guide ring has a hollow part, and the side wall of the guide ring has at least one cooling channel, so that a flow path is provided for the cooling liquid to realize cooling during drilling. The cooling channel is in communication with the hollow part, and the cooling channel penetrates the side wall of the guide ring along the radial direction of the guide ring or is arranged on the inner surface of the side wall of the guide ring and extends along the axial direction of the guide ring. The thickness of the side wall of the guide ring which is in contact with the outer surface of the drill bit is the same, and there is no thin wall, so that the drill bit does not drill through the guide ring during drilling. Since the cooling channel is in communication with the hollow part, part of the outer surface of the drill bit is located at the junction of the cooling channel and the hollow part, the contact area of the side wall of the guide ring and the drill bit is reduced, the wear of the drill bit is reduced, and the service life of the drill bit is prolonged. Therefore, the planting guide plate provided by the application not only ensures that the cooling liquid can flow into the target area during drilling, but also reduces the loss of the drill bit and reduces the cost.

Description

Technical Field

[0001] This invention relates to the field of dental implant technology, and in particular to an implant guide plate. Background Technology

[0002] Currently, in dental implant surgery, to improve the precision and safety of the procedure, dentists use implant guides to ensure the accuracy of the implant's position, angle, and depth. Implant guides prevent damage to the alveolar nerve and perforation of the maxillary sinus floor, while also ensuring the implant is placed in the designated location to achieve the desired restorative effect.

[0003] To prevent the drill bit from directly contacting the implant guide during drilling and causing debris to fall out, and to ensure the drill bit accurately enters the designated position, a guide ring needs to be embedded in the guide hole of the dental implant guide. However, because of the guide ring and the close contact between the guide and the gingiva at the implantation site, it is difficult for coolant to enter the surgical site through the guide ring during the operation, making it impossible to effectively cool the implant area. If excessive heat generated during drilling cannot be dissipated in time, it can cause side effects such as bone burns, leading to implant failure. Furthermore, the friction between the guide ring and the drill bit during the use of the guide causes greater drill bit wear, reducing the drill bit's lifespan and increasing consumable costs.

[0004] To address this, existing technologies often involve setting overflow holes on the guide plate body and connecting them to the guide hole. However, because the outer diameter of the drill bit is tightly fitted with the inner diameter of the guide hole, it is difficult for coolant to enter from the guide hole and flow out through the overflow hole during drilling. If there is a gap between the outer diameter of the drill bit and the inner diameter of the guide hole, precise positioning cannot be achieved.

[0005] Therefore, a new planting guide is needed to solve the above-mentioned technical problems. Summary of the Invention

[0006] The purpose of this invention is to provide a planting guide plate to solve at least one of the problems of how to achieve cooling during drilling and how to reduce drill bit wear.

[0007] To solve the above-mentioned technical problems, the present invention provides a planting guide plate, including a fixing member and a guide ring;

[0008] The guide ring is inserted into the fixing member, the guide ring has a hollow part, and the side wall of the guide ring has at least one cooling channel, the cooling channel being connected to the hollow part;

[0009] The cooling channel penetrates the sidewall of the guide ring radially, or is disposed on the inner surface of the sidewall of the guide ring, and extends axially along the guide ring.

[0010] Optionally, in the planting guide plate, the area of ​​the interface between the cooling channel and the hollow part is less than or equal to 2 / 3 of the area of ​​the inner surface of the sidewall of the guide ring.

[0011] Optionally, in the planting guide plate, along the axial direction of the guide ring, the cooling channel connects two opposing surfaces at both ends of the guide ring, so that coolant flows into the target area through the cooling channel.

[0012] Optionally, in the planting guide plate, the interface between the cooling channel and the sidewall of the guide ring is planar and / or curved.

[0013] Optionally, in the planting guide plate, the guide ring has a plurality of cooling channels; the cooling channels extend linearly along the axial direction of the guide ring, and all the cooling channels are arranged at intervals along the circumference of the guide ring.

[0014] Optionally, in the planting guide plate, the cooling channel is an opening that connects the inner and outer surfaces of the sidewall of the guide ring; the planting guide plate also includes a plurality of connectors, which are placed in the opening and both ends of the connectors are connected to the sidewall of the guide ring.

[0015] Optionally, in the planting guide plate, the connector is rod-shaped or plate-shaped.

[0016] Optionally, in the planting guide plate, the planting guide plate further includes a plurality of limiting members, which are connected to the fixing member, and the limiting members are used to limit the axial and circumferential positions of the guide ring; wherein, along the radial direction of the guide ring, the thickness of the limiting member is less than the thickness of the sidewall of the guide ring.

[0017] Optionally, in the planting guide plate, the cooling channel is a groove provided on the inner surface of the side wall of the guide ring, the groove extending linearly along the axial direction of the guide ring; and / or, the groove surrounds the side wall of the guide ring and extends spirally along the axial direction of the guide ring.

[0018] Optionally, in the implant guide plate, the fixation member is a housing with a guide hole, and the guide ring passes through the guide hole into the fixation member; wherein, the contour of the inner wall of the fixation member is adapted to at least the outer surface of the adjacent tooth of the affected tooth.

[0019] In summary, this invention provides a planting guide plate, including a fixing member and a guide ring. The guide ring is inserted into the fixing member, has a hollow portion, and its sidewall has at least one cooling channel. The cooling channel provides a flow path for coolant, ensuring that coolant can flow into the target area in a timely manner during drilling, achieving a cooling effect. Furthermore, the cooling channel is connected to the hollow portion; the cooling channel penetrates the sidewall of the guide ring radially, or is at least located on the inner surface of the sidewall of the guide ring, and extends axially along the guide ring. Therefore, the sidewall thickness of the guide ring that contacts the outer surface of the drill bit is uniform, eliminating thin walls and preventing the drill bit from penetrating the guide ring during drilling. Simultaneously, because the at least one cooling channel is connected to the hollow portion, a portion of the outer surface of the drill bit is located at the junction of the cooling channel and the hollow portion, reducing the contact area between the sidewall of the guide ring and the drill bit, thus reducing drill bit wear and extending its service life. Therefore, the planting guide plate provided by the present invention not only ensures that coolant can flow into the target area during drilling, but also reduces drill bit wear and reduces costs.

[0035] To make the objectives, advantages, and features of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that the drawings are all in a very simplified form and are not drawn to scale, and are only used to facilitate and clearly illustrate the objectives of the embodiments of the present invention. Furthermore, the structures shown in the drawings are often part of the actual structures. In particular, different figures may emphasize different aspects and sometimes use different scales. It should also be understood that, unless specifically stated or indicated, the terms "first," "second," "third," etc., in the specification are only used to distinguish the various components, elements, steps, etc., in the specification, and are not used to indicate the logical or sequential relationships between the various components, elements, steps, etc.

[0036] This embodiment provides a planting guide plate. For example... Figure 1-3 As shown, the planting guide plate includes a fixing member 11 and a guide ring 12; the guide ring 12 passes through the fixing member 11, the guide ring 12 has a hollow portion 123, and the side wall of the guide ring 12 has at least one cooling channel, the cooling channel being connected to the hollow portion 123; the cooling channel penetrates the side wall of the guide ring 12 radially, or is provided on the inner surface of the side wall of the guide ring 12, and extends along the axial direction of the guide ring 12.

[0037] Therefore, the guide ring 12 provided in this embodiment provides a flow path for the coolant by setting the cooling channel, ensuring that the coolant can flow into the target area in a timely manner during drilling, thereby achieving a cooling effect. Furthermore, since at least one of the cooling channels is connected to the hollow portion 123, a portion of the outer surface of the drill bit is located at the junction of the cooling channel and the hollow portion 123, reducing the contact area between the sidewall of the guide ring 12 and the drill bit, thus reducing drill bit wear and extending its service life. Additionally, the sidewall thickness of the guide ring 12, which is in contact with the outer surface of the drill bit, is the same, eliminating thin walls and preventing the drill bit from drilling through the guide ring 12 during drilling.

[0038] The fixation member 11 is a shell used to fix the position of the guide ring 12 during implant surgery. Therefore, the contour of the inner wall of the fixation member 11 is adapted to at least the outer surface of the adjacent tooth of the affected tooth, or to the overall outer surface of the upper or lower row of teeth containing the affected tooth, so that the fixation member can be fitted onto the teeth near the affected tooth. Currently, computer-aided design and additive manufacturing technologies are used domestically and internationally to reconstruct a three-dimensional model using cone beam computed tomography (CBCT) data of the patient's oral and maxillofacial region to determine the placement position of the guide ring 12 and the morphology of the fixation member 11, and then the fixation member 11 is formed using 3D printing technology. During the fabrication of the fixation member 11, a guide hole (not shown) is provided at the placement position of the guide ring 12 so that the subsequently formed guide ring 12 can pass through the guide hole into the fixation member 11. Furthermore, the number of guide rings 12 embedded in the fixing member 11 is determined according to the number of affected teeth, and this embodiment does not limit this.

[0039] The guide ring 12 is used to guide and fix the position of the drill bit, ensuring the accuracy of the drilling position. The guide ring 12 is cylindrical, and its two opposite end faces are connected by a hollow portion 123, so the cross-section of the guide ring 12 is similar to an annular shape. Furthermore, along the axial direction of the guide ring 12, the cooling channel connects the two opposite annular surfaces of the guide ring 12, so that coolant can flow in through one end of the cooling channel and out through the other end. Thus, even after the drill bit extends into the hollow portion 123 and blocks the interface between the hollow portion 123 and the cooling channel, the coolant can still flow into the target area through the cooling channel.

[0040] Please see Figure 2 and 3In one embodiment, the cooling channel extends radially through the sidewall of the guide ring 12, forming an opening 121. The opening 121 connects the inner and outer surfaces of the sidewall of the guide ring 12. In another embodiment, the cooling channel is located on the inner surface of the sidewall of the guide ring 12. That is, the cooling channel is recessed into the sidewall of the guide ring 12. Figure 3 As shown, viewed from the cross-section of the guide ring 12, the groove 122 occupies a portion of the sidewall of the guide ring 12, but does not connect the inner and outer surfaces of the sidewall; it is only connected to the hollow portion 123. Alternatively, in other embodiments, the guide ring 12 has multiple cooling channels, some of which are openings 121, and some of which are grooves 122.

[0041] Therefore, the cooling channel provided in this application can be an opening 121 that radially penetrates the sidewall of the guide ring 12, or it can be a groove 122 (i.e., a blind groove structure) embedded in the sidewall of the guide ring 12, to provide a channel for coolant to flow into the target area during drilling. Furthermore, when drilling, the drill bit extends into the hollow portion 123, so that the outer surface of the drill bit is in contact with the sidewall of the guide ring 12. The sidewall thickness of the guide ring 12 in contact with the outer surface of the drill bit is uniform, eliminating thin walls and preventing the drill bit from penetrating the guide ring 12 due to uneven sidewall thickness during drilling. Additionally, part of the outer surface of the drill bit is located at the junction of the cooling channel and the hollow portion 123, reducing the contact area between the sidewall of the guide ring 12 and the drill bit, thereby reducing drill bit wear and extending its service life. Furthermore, this embodiment does not limit the specific shape of the cooling channel. The cooling channel can be rectangular, fan-shaped, triangular, wavy, cylindrical, spiral, or polygonal, etc.

[0042] Furthermore, since the main function of the guide ring 12 is to ensure the precise positioning of the drill bit, the volume occupied by the cooling channel on the side wall of the guide ring 12 should not be too large, but it should not be too small to ensure the cooling effect. The larger the area of ​​the interface between the cooling channel and the hollow portion 123, the more coolant passes through, resulting in a better cooling effect and less wear on the drill bit. However, the accuracy of the drill bit position is provided by the guide ring 12. If the contact area between the guide ring 12 and the drill bit is too small, it will cause the drill bit to wobble, making it impossible to accurately control the drilling position and direction. Therefore, preferably, in the guide ring 12, the total area of ​​the interfaces between all the cooling channels and the hollow portion 123 is less than or equal to 2 / 3 of the inner surface area of ​​the side wall of the guide ring 12.

[0043] Please see Figure 2-4Provided that the area ratio between the cooling channel and the hollow portion 123 is satisfied, the number of cooling channels can be one, two, or three, etc., and this embodiment does not limit the specific number. Figure 2 The guide ring 12 shown has an opening 121 on its side wall; Figure 3 The guide ring 12 shown has four grooves 122 on its side wall; Figure 4 The guide ring 12 shown has three openings 121 on its sidewall. When the guide ring 12 has multiple openings 121 or grooves 122 on its sidewall, and these openings 121 or grooves 122 extend linearly along the axial direction of the guide ring 12, preferably, the multiple openings 121 or grooves 122 are arranged at intervals along the circumference of the guide ring 12, which facilitates uniform heat dissipation of the drill bit during drilling. The cooling channels can be arranged at equal or non-equal intervals. Furthermore, the multiple openings 121 or grooves 122 reduce the contact area between the sidewall of the guide ring 12 and the drill bit, thereby reducing drill bit wear and extending its service life.

[0044] Please see Figure 2-5 As shown, this embodiment does not limit the shape of the channel cavity wall formed by the sidewall of the guide ring 12, and can be any shape. Figure 2 and Figure 4 The plane shown can also be Figure 5 The surface shown is, or is Figure 3 The shown diagram shows that some channel walls are planar, while others are curved. Figure 5 The wavy opening 121 shown can increase the contact area between the coolant and the drill bit to achieve a better cooling effect.

[0045] Furthermore, such as Figure 6 As shown, when the cooling channel is an opening 121, the sidewalls of the guide ring 12 are spaced apart. Especially when multiple openings 121 are provided, the sidewalls of the guide ring 12 are circumferentially separated into multiple sub-sidewalls. To ensure the stability of the guide ring 12 in fixing the drill bit, preferably, the planting guide plate also includes multiple connectors 124. The connectors 124 are placed in the openings 121, and their two ends are respectively connected to the sidewalls of the guide ring 12 to ensure the circumferential integrity of the sidewalls of the guide ring 12 and to facilitate installation into the fixing member. It can be understood that the connectors 124 connect adjacent sub-sidewalls to connect the various sub-sidewalls of the guide ring 12.

[0046] Furthermore, the connector 124 can be rod-shaped. The rod-shaped connector 124 can be a straight rod or a curved rod. One, two, or more rod-shaped connectors 124 can be provided between adjacent sub-sidewalls; this embodiment does not limit this. Additionally, the connector 124 can also be plate-shaped, in which case the plate surface of the plate-shaped connector 124 can be planar or curved. Figure 3 The guide ring 12 shown can be considered as the connecting member 124 with an arc-shaped surface connecting to the adjacent sub-sidewall. This embodiment does not specifically limit the shape of the connecting member 124; it can be rectangular, cylindrical, triangular, or polygonal, etc. Furthermore, the connecting member 124 is integrally formed with the guide ring 12. Along the radial direction of the guide ring 12, the thickness of the connecting member 124 is less than the thickness of the sidewall of the guide ring 12; that is, the connecting member 124 does not protrude from the inner surface of the sidewall of the guide ring 12, to ensure that it does not affect the insertion of the drill bit.

[0047] Please see Figure 7-8 Because the guide ring 12 has openings 121, especially when multiple openings 121 are provided, it is difficult to accurately determine the connection position when the guide ring 12 is connected to the fixation member. This may lead to tilting or unevenness of the sub-sidewalls of the guide ring 12. To address this, the implant guide plate also includes multiple limiting members 111 to limit the axial and circumferential positions of the guide ring 12. The multiple limiting members 111 are connected to the fixation member, preferably integrally formed with the fixation member. Specifically, the limiting members 111 are correspondingly located on both sides of each sub-sidewall, i.e., limiting the circumferential position of each sub-sidewall, and at the junction of the surface of the guide ring 12 facing the extraction socket and the fixation member, i.e., limiting the axial position of each sub-sidewall. Figure 7 As shown, the limiting member 111 is a protrusion, and multiple protrusions limit the position of the guide ring 12 on the fixing member to ensure the precise fixation of the guide ring 12 on the drill bit. Furthermore, the limiting member 11 can also be strip-shaped, such as... Figure 8 As shown. In this embodiment, the shape of the limiting member 111 is not specifically limited; it can be rectangular, cylindrical, triangular, or polygonal, etc. Specifically, along the radial direction of the guide ring 12, the thickness of the limiting member 111 is less than the thickness of the sidewall of the guide ring 12; that is, the limiting member 111 does not extend beyond the inner surface of the sidewall of the guide ring 12, to ensure that it does not affect the insertion of the drill bit.

[0048] Please see Figure 3 and Figure 9-12 When the cooling channel has a groove structure, the cooling channel can be... Figure 3 The groove 122 shown extends linearly along the axial direction of the guide ring 12; it can also be... Figure 9-10The groove 125 shown surrounds the sidewall of the guide ring 12 and extends spirally along the axial direction of the guide ring 12; it can also be a combination of the two, such as... Figure 11-12 As shown. Among them, Figure 9-12 The spiral grooves 125 in the guide ring 12 provide more cooling channels while ensuring drilling accuracy. Simultaneously, during drilling, the rotation of the drill bit drives the coolant along the spiral grooves 125 on the guide ring 12 towards the target position. The spiral shape allows the coolant to achieve a faster flow rate, enhancing coolant exchange, promptly removing heat, and achieving a better cooling effect.

[0049] This embodiment is preferred. Figure 11-12 The guide ring 12 shown has multiple fan-shaped grooves 122 extending linearly along the axial direction of the guide ring 12, and spiral grooves 125 extending along the axial direction of the guide ring 12, spaced apart on its sidewalls. The two types of grooves 122 and 125 work together to allow coolant to flow into the alveolar bone in two directions. Specifically, coolant enters the guide ring along the vertical grooves 122, and during drill bit rotation, the incoming low-temperature coolant is rapidly delivered to the grooves 125, greatly accelerating the coolant exchange rate and reducing the coolant's residence time within the guide ring 12. Furthermore, the multiple grooves 122 reduce the contact area between the guide ring 12 sidewall and the drill bit, significantly reducing drill bit wear and extending its service life.

[0050] In summary, this embodiment provides a planting guide plate, including a fixing member 11 and a guide ring 12. The guide ring 12 is inserted into the fixing member 11, has a hollow portion 123, and its sidewall has at least one cooling channel. This cooling channel provides a flow path for coolant, ensuring that coolant can flow into the target area in a timely manner during drilling, achieving a cooling effect. Furthermore, the cooling channel is connected to the hollow portion 123; the cooling channel penetrates the sidewall of the guide ring 12 radially, or is located on the inner surface of the sidewall of the guide ring 12, and extends axially along the guide ring 12. Therefore, the sidewall thickness of the guide ring 12, which is in contact with the outer surface of the drill bit, is uniform, eliminating thin walls and preventing the drill bit from penetrating the guide ring during drilling. Meanwhile, because the sidewall of the guide ring 12 is provided with at least one cooling channel and is connected to the hollow portion 123, a portion of the outer surface of the drill bit is located at the junction of the cooling channel and the hollow portion 123, reducing the contact area between the sidewall of the guide ring 12 and the drill bit. This reduces drill bit wear and extends its service life. Therefore, the planting guide plate provided in this embodiment not only ensures that coolant can flow into the target area during drilling but also reduces drill bit wear and lowers costs.

[0051] Furthermore, it should be understood that although the present invention has been disclosed above with reference to preferred embodiments, these embodiments are not intended to limit the present invention. For any person skilled in the art, many possible variations and modifications can be made to the technical solutions of the present invention based on the disclosed technical content, or equivalent embodiments can be modified accordingly, without departing from the scope of the present invention. Therefore, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention, without departing from the content of the present invention, shall still fall within the scope of protection of the present invention.
