[0002] During the dental implant procedure, many steps require drilling, such as the implant placement holes and the bone harvesting holes. The accuracy of drilling these holes directly affects the implant placement accuracy. Currently, drilling is mostly done manually by the doctor, which is very demanding on the doctor's skills, making the procedure very energy-consuming and time-consuming.

[0003] To address the aforementioned issues, this utility model document proposes an oral cavity drilling guide and locator for dental implants. Utility Model Content

[0004] This invention provides a dental implant drilling guide and locator, which improves drilling accuracy, reduces the difficulty of drilling operations, and increases work efficiency.

[0005] This utility model provides the following technical solution:

[0006] A dental implant drilling guide locator includes a guide locating head and a locking handle rod. The guide locating head has a slot on its side, and a sliding groove is provided along the side wall of the slot. A positioning cylinder is slidably disposed in the slot. The positioning cylinder has a positioning ring on its side that cooperates with the sliding groove. The guide locating head has a threaded hole and a positioning rod on the side with the slot, and the threaded hole and the positioning rod are respectively located on both sides of the slot.

[0007] The locking handle includes a positioning sleeve, a handle, and a push rod. One end of the positioning sleeve has a through hole that mates with a threaded hole and a positioning hole that mates with the positioning rod along its length direction. The threaded hole is adjacent to this end of the positioning sleeve. The other end of the positioning sleeve is threadedly connected to the handle. The handle end is provided with a push rod, which is inserted into the positioning sleeve and mates with the positioning rod.

[0008] The guide positioning head is located on the locking handle rod, and the locking bolt passes through the through hole and is fixed in conjunction with the threaded hole. The positioning rod is inserted into the positioning hole.

[0009] Furthermore, the inner wall of the end of the positioning sleeve away from the through hole is provided with an internal thread, and the end face of the handle rod is provided with a cylindrical connecting block. The diameter of the connecting block matches the diameter of the positioning sleeve, and the side of the connecting block is provided with an external thread that mates with the internal thread. The push rod is vertically arranged on the end face of the connecting block.

[0010] Furthermore, the side surface of one end of the positioning sleeve with the through hole and the positioning hole is flat.

[0029] Example:

[0030] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, a dental implant drilling guide locator includes a guide locating head 1 and a locking handle 8 rod 2. The guide locating head 1 has a slot 3 on its side. The slot 3 has a sliding groove 4 along its side wall. A positioning cylinder 5 is slidably disposed in the slot 3. The positioning cylinder 5 has a positioning ring 15 that cooperates with the sliding groove 4 on its side. The guide locating head 1 has a threaded hole 6 and a positioning rod 7 on its side with the slot 3. The threaded hole 6 and the positioning rod 7 are located on both sides of the slot 3.

[0031] The locking handle 8 rod 2 includes a positioning sleeve 11, a handle 8 and a push rod 10. One end of the positioning sleeve 11 is provided with a through hole 13 that mates with a threaded hole 6 and a positioning hole 12 that mates with a positioning rod 7 along its length direction. The threaded hole 6 is adjacent to this end of the positioning sleeve 11. The other end of the positioning sleeve 11 is threadedly connected to the handle 8. The end of the handle 8 is provided with a push rod 10. The push rod 10 is inserted into the positioning sleeve 11 and mates with the positioning rod 7.

[0032] The guide positioning head 1 is located on the locking handle 8 rod 2. The locking bolt 14 passes through the through hole 13 and is fixed in conjunction with the threaded hole 6. The positioning rod 7 is inserted into the positioning hole 12.

[0033] The guide positioning head 1 is installed on the positioning sleeve 11, with the threaded hole 6 corresponding to the through hole 13. The positioning rod 7 is inserted into the positioning hole 12, and the locking bolt 14 passes through the through hole 13 and engages with the threaded hole 6 to fix the guide positioning head 1 on the positioning sleeve 11.

[0034] The guide positioning head 1 can be locked in the position where a hole needs to be drilled. The positioning cylinder 5 slides along the slide groove 4 in the slot 3. The position of the positioning cylinder 5 is adjusted according to the drilling position so that the position of the positioning cylinder 5 corresponds to the drilling position. The handle 8 rotates in the positioning sleeve 11, which can drive the top rod 10 to rotate together. The handle 8 is screwed into the positioning sleeve 11, and the top rod 10 moves in the direction of the positioning rod 7, pressing the positioning rod 7. The positioning rod 7 moves, and the positioning rod 7 is fixed on one side of the slot 3, thus pressing the slot 3, thereby clamping and positioning the positioning cylinder 5 in the slot 3. This makes the position of the positioning cylinder 5 the drilling position, improving the drilling accuracy, reducing the difficulty of drilling operation, and improving work efficiency.

[0035] The inner wall of the end of the positioning sleeve 11 away from the through hole 13 is provided with an internal thread. The end face of the handle 8 rod is provided with a cylindrical connecting block 9. The diameter of the connecting block 9 matches the diameter of the positioning sleeve 11, and the side of the connecting block 9 is provided with an external thread that matches the internal thread. The push rod 10 is vertically set on the end face of the connecting block 9.

[0036] The handle 8 is connected to the positioning sleeve 11 by the external thread on the connecting block 9 and the internal thread, allowing the handle 8 to rotate and connect with the positioning cylinder 5, thereby positioning the position of the push rod 10 so that the push rod 10 can cooperate with the positioning rod 7. As the handle 8 rotates, the push rod 10 moves closer to or away from the positioning rod 7. When the push rod 10 moves closer to the positioning rod 7 and abuts against it, the push rod 10 continues to move, pressing the positioning rod 7, causing the positioning rod 7 to move one side of the slot 3 to clamp and fix the positioning cylinder 5 in the slot 3. When the push rod 10 moves away from the positioning rod 7, it releases the positioning cylinder 5, thus adjusting the position of the positioning cylinder 5.

[0037] The side surface of one end of the positioning sleeve 11 with the through hole 13 and the positioning hole 12 is flat.

[0038] The side of the positioning sleeve 11 is set as a plane, which makes the structure of the guide positioning head 1 installed on the positioning sleeve 11 more stable and further improves the stability of the connection structure between the guide positioning head 1 and the positioning cylinder 5.

[0039] The side of the positioning rod 7 that mates with the top rod 10 is a flat surface.

[0040] The surface where the positioning rod 7 and the top rod 10 mate is made into a plane to increase the contact area between the top rod 10 and the positioning rod 7, ensuring that the top rod 10 can squeeze the positioning rod 7, so that the positioning rod 7 can move under force, thereby ensuring that the positioning rod 7 can drive one side of the guide positioning head 1 to clamp and fix the positioning cylinder 5 in the slot 3. The plane prevents the top rod 10 from sliding and deviating when squeezing the positioning rod 7, which would cause damage to the top rod 10 or the positioning rod 7.

[0041] The cross-section of the guide positioning head 1 is trapezoidal, and the slot 3 is located on the wider end of the guide positioning head 1.

[0042] The guide positioning head 1 is trapezoidal. When the guide positioning head 1 is placed in the drilling position of the oral cavity, it can adapt to drilling areas of different widths, thus improving the adaptability of the guide positioning device.

[0043] The surface of the guide positioning head 1 is also evenly provided with graduated grooves 17 along the length of the slot 3.

[0044] The scale groove 17 allows doctors to observe the length of the guide positioning head 1 inserted into the drilling area, and thus determine the width of the drilling area.

[0045] The positioning cylinder 5 has limiting plates 16 at both ends, and the length of the positioning cylinder 5 is the same as the thickness of the guide positioning head 1.

[0046] The limiting plate 16 can prevent the positioning cylinder 5 from falling out of the slot 3, and improve the stability of the positioning cylinder 5 moving in the slot 3, so as to avoid the positioning cylinder 5 from deflecting in the slot 3 and affecting the drilling direction.

[0047] In use, the positioning cylinder 5 is placed in the slot 3, the positioning ring 15 on the side of the positioning cylinder 5 is placed in the sliding groove 4 on the side wall of the slot 3, and the limiting plates 16 at both ends of the positioning cylinder 5 abut against the two surfaces of the guide positioning head 1. The threaded hole 6 on the guide positioning head 1 is aligned with the through hole 13 at the end of the positioning sleeve 11, and the positioning rod 7 on the guide positioning head 1 is aligned with the positioning hole 12 on the positioning sleeve 11. Then, the guide positioning head 1 is pressed against the positioning sleeve 11, so that the positioning rod 7 is inserted into the positioning hole 12. Then, the locking bolt 14 passes through the through hole 13 and engages with the threaded hole 6, thereby fixing the guide positioning head 1 onto the positioning sleeve 11. Then, the handle 8 is threadedly connected and installed on the positioning sleeve 11 by engaging the external thread on the connecting block 9 with the internal thread at the end of the positioning sleeve 11. The push rod 10 is inside the positioning sleeve 11, and the end of the push rod 10 is adjacent to the positioning rod 7.

[0048] During drilling and positioning, the smaller-diameter end of the trapezoidal guide positioning head 1 is inserted into the drilling position. After the guide positioning head 1 is stably positioned in the drilling position, the position of the positioning cylinder 5 in the slot 3 is moved so that the middle of the positioning cylinder 5 corresponds to the drilling point. Then, the handle 8 is rotated, causing the handle 8 to move the push rod 10 in the direction of the positioning rod 7. After the push rod 10 abuts against the side of the positioning rod 7, it continues to hold the positioning rod 7, causing the positioning rod 7 to move in the direction of the threaded hole 6. This, in turn, causes one side of the guide positioning head 1 to press against the other side, while simultaneously, one side wall of the slot 3 presses against the other side wall. Then, the positioning cylinder 5 in the slot 3 is clamped and fixed, and the doctor can pass the drilling bit through the positioning cylinder 5 to directly perform the drilling operation, ensuring the drilling accuracy and reducing the difficulty of the doctor's drilling operation, thereby ensuring the installation accuracy of the implant; after the drilling is completed, the handle 8 is rotated in the opposite direction, so that the handle 8 moves away from the guide positioning head 1, and at the same time, it drives the push rod 10 away from the positioning rod 7. After the positioning rod 7 is no longer squeezed by the push rod 10, it returns to the initial position. At the same time, the guide positioning head 1 releases the positioning cylinder 5 in the slot 3, so that the position of the positioning cylinder 5 can be adjusted for the next use.

[0049] In actual use, a reset spring is installed between the two side walls of the opening of the slot 3 so that after the top rod 10 separates from the positioning rod 7, the guide positioning head 1 will no longer clamp the positioning cylinder 5.

[0050] The top rod 10, connecting block 9 and handle 8 are integrally formed, which improves the overall structural strength of the locking handle 8 rod 2 and also facilitates processing and manufacturing.

[0051] The contact surface between the positioning ring 15 and the slide groove 4 is a plane, which increases the contact surface between the positioning ring 15 and the slide groove 4, prevents the positioning cylinder 5 from rolling inside the slide groove 4, and improves the stability of the positioning cylinder 5 when clamped.

[0052] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. In the absence of conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
