Description

Technical Field

[0001] The invention belongs to the technical field of oral medical instruments, and in particular relates to an implant nail auxiliary positioning device. Background Art

[0002] In the field of oral implants, dental implant templates include removable dentures, self-bonding plates and traditional technologies using compression molding technology. However, with the continuous development of oral implant technology and patients' increasing requirements for implant effects, these traditional technologies have exposed many problems in implant pin implantation.

[0003] Traditional removable dentures and self-adhesive plates have obvious disadvantages in assisting implantation. First, the operational stability is poor. Due to the poor fit between their structure and oral tissue, they are prone to displacement or shaking during the operation, resulting in positioning deviation during implantation. Secondly, the production process is complicated and requires multiple tedious procedures, which not only takes a lot of time, but also has extremely high technical requirements for operators. The slightest carelessness will lead to insufficient product precision, thereby increasing the risk of failure. They will seriously block the field of vision during surgery, making it difficult for doctors to clearly observe the specific situation of the implant site, and they have to rely on rich clinical experience to judge. For inexperienced doctors, the difficulty and risk of surgery are significantly increased. Although the auxiliary tools designed using the film pressing technology have improved the fitting problem to a certain extent, the visual field exposure is not sufficient, and the doctor cannot fully and clearly observe the implant area, which is not conducive to precise operation. In addition, there is a lack of accurate and effective mechanism to guide the implantation direction of the implant, and it is difficult to ensure that the implant is implanted at the ideal angle and depth. This also makes the surgical effect highly dependent on the doctor's clinical experience and operating skills, and the technical requirements for the doctor remain high. Summary of the invention

[0004] The purpose of the present invention is to provide an implant pin auxiliary positioning device to solve the technical problems of poor operational stability, low precision, high cost and poor surgical field of view during surgery using removable dentures and self-bonding plates; in addition, the production is complex, the precision is low, the price is high, the field of view is not exposed enough and the direction is imprecise when using the lamination technology, and the doctor's clinical experience is relied on and the technical requirements are high.

[0005] The technical solution adopted by the present invention is as follows:

[0006] An implant nail auxiliary positioning device, comprising:

[0007] Laminated braces, the laminated braces match the teeth, and both ends of the laminated braces are fixedly connected with fixed wings that slide and engage with adjacent teeth;

[0008] The positioning channel is opened on the laminated braces, and a first adjustment mechanism for changing the depth of the positioning channel and a second adjustment mechanism for changing the diameter of the positioning channel are arranged in the positioning channel. The inner wall of the positioning channel is coated with a smooth coating.

[0009] Wherein, the space between the outer side of the seating channel and the inner side of the laminated dental brace is filled with self-curing plastic, which is a fast-curing and highly transparent material and is added with a trace amount of developer material.

[0010] The self-curing plastic is composed of polyurethane acrylate and high-efficiency photoinitiator, with special anti-transmission aid and inorganic filler added, and the developer material is iohexol.

[0011] Wherein, the first adjustment mechanism comprises a threaded sleeve threadedly installed in the seating channel, and the threaded sleeve is provided with a hexagonal groove.

[0012] Among them, the second adjustment mechanism includes two arc-shaped clamping blocks arranged in the threaded sleeve, the two arc-shaped clamping blocks are symmetrically arranged, and a limit spring is fixedly installed between the side of the two arc-shaped clamping blocks close to each other and the inner wall of the threaded sleeve. The two arc-shaped clamping blocks are provided with an adjustment block, and a first thread groove is opened on the inner wall of the threaded sleeve close to the adjustment block. The bottom of the adjustment block is threadedly connected to the first thread groove, and a cross groove is opened on the upper end of the adjustment block.

[0013] Among them, the adjustment block is composed of an upper conical block and a cylindrical block, the outer wall of the cylindrical block is threadedly connected to the first thread groove, and the two arc-shaped clamping blocks are arranged in a trumpet shape at one end close to the adjustment block, and the upper conical block on the adjustment block is slidably connected to the trumpet-shaped inner walls at the lower ends of the two arc-shaped clamping blocks.

[0014] Wherein, the inner surfaces opposite to each other of the two arc-shaped clamping blocks are provided with second thread grooves, and the shape and size of the second thread grooves match the threads of the implant nails used.

[0015] Wherein, the smooth coating is made of polytetrafluoroethylene material.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0017] In the present invention, a laminated brace is used to match the teeth, and the fixed wings at both ends are slidably engaged with the adjacent teeth, which greatly improves the intraoperative stability and changes the current situation of poor stability of removable dentures and self-binding plates. The first adjustment mechanism and the second adjustment mechanism in the insertion channel can accurately control the depth and diameter, effectively improve the implantation accuracy, and solve the problem of low accuracy of traditional methods.

[0023] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0024] Reference Figure 1-Figure 3 A implant screw auxiliary positioning device includes a laminated brace 10 and a positioning channel 20. The laminated brace 10 matches the teeth. Both ends of the laminated brace 10 are fixedly connected with fixed wings 11 that are slidably engaged with adjacent teeth. The laminated brace 10 is provided with a positioning channel 20. The positioning channel 20 is provided with a first adjustment mechanism for changing the depth of the positioning channel 20 and a second adjustment mechanism for changing the diameter of the positioning channel 20. The inner wall of the positioning channel 20 is coated with a smooth coating 12.

[0025] Specifically, the laminated dental braces 10 match the teeth, and the fixed wings 11 at both ends are slidably engaged with the adjacent teeth, which can stabilize the positioner in the oral cavity, prevent shaking during the operation, and improve the stability of operation. The first adjustment mechanism in the positioning channel 20 can accurately adjust the depth, and the second adjustment mechanism can flexibly change the diameter, allowing the doctor to achieve fine control of the parameters of the positioning channel 20 according to the implantation needs and the patient's oral condition, thereby improving the accuracy of implantation of the implant screw. The smooth coating 12 coated on the inner wall can reduce the friction during the implantation of the implant screw, ensuring a smoother implantation process, and reducing the risk of damage to the surface of the implant screw, thereby comprehensively optimizing the implant screw implantation operation process.

[0026] Reference Figure 1 As shown, the self-curing plastic 101 is filled between the outer side of the seating channel 20 and the inner side of the laminated braces 10. The self-curing plastic 101 is a fast-curing and highly transparent material, and is added with a trace amount of developer material. The self-curing plastic 101 has a fast-curing characteristic, which can quickly stabilize the relative position of the seating channel 20 and the laminated braces 10, shorten the operation waiting time, and improve the efficiency of the operation. Its high transparency can ensure that the doctor has a clear field of vision during the operation, which is convenient for observing the condition of the implant pins and surrounding tissues. The added trace developer material can make the self-curing plastic 101 and the implant pins clearly visible under X-ray and other imaging equipment, which is convenient for the doctor to accurately position and ensure that the implant pins are accurately implanted at the predetermined position, thereby comprehensively improving the accuracy and safety of the implant surgery.

[0027] Reference Figure 1 As shown, the self-curing plastic 101 is composed of polyurethane acrylate and a high-efficiency photoinitiator, with special anti-transmission aids and inorganic fillers added, and the developer material is iohexol.

[0028] In detail, the main component of self-curing plastic 101 is polyurethane acrylate, which has good flexibility and mechanical properties, and the acrylate group is conducive to rapid curing. Combined with the high-efficiency photoinitiator 2-hydroxy-2-methyl-1-phenyl-1-propanone, under the irradiation of light of a specific wavelength, the material can be transformed from liquid to solid within a few seconds to more than ten seconds, which significantly improves the efficiency of surgery. By adding special anti-reflection agents, the molecular arrangement is optimized and the transparency is greatly improved, allowing doctors to clearly observe the surgical site. At the same time, inorganic fillers such as nano-silica are introduced to enhance the mechanical strength of the material without affecting the transparency, ensuring that the positioning device is stable and reliable in complex stress environments, and comprehensively solving the problems of poor operation stability, low precision and poor field of vision during surgery.

[0029] Reference Figure 2As shown, the first adjustment mechanism includes a threaded sleeve 21 threadedly installed in the positioning channel 20, and a hexagonal groove 212 is provided on the threaded sleeve 21. By rotating the threaded sleeve 21, its position in the positioning channel 20 can be changed, thereby adjusting the depth of the positioning channel 20. The hexagonal groove 212 is convenient for doctors to insert a hexagonal wrench, making the rotation operation more convenient and accurate, thereby effectively controlling the depth of implantation of the implant nail.

[0030] Reference Figure 2 and Figure 3 As shown, the second adjustment mechanism includes two arc-shaped clamping blocks 22 arranged in the threaded sleeve 21, the two arc-shaped clamping blocks 22 are symmetrically arranged, and a limit spring 23 is fixedly installed between the side of the two arc-shaped clamping blocks 22 close to each other and the inner wall of the threaded sleeve 21, and the two arc-shaped clamping blocks 22 are provided with an adjustment block 24. The inner wall of the threaded sleeve 21 close to the adjustment block 24 is provided with a first thread groove 211, and the bottom of the adjustment block 24 is threadedly connected to the first thread groove 211, and the upper end of the adjustment block 24 is provided with a cross Slot 241, insert the cross slot 241 at the upper end of the adjusting block 24 through a tool to rotate the adjusting block 24, since the bottom of the adjusting block 24 is threadedly connected with the first thread groove 211 on the inner wall of the threaded sleeve 21, rotating the adjusting block 24 can make it move along the first thread groove 211, and under the elastic force of the two limit springs 23, push or pull the two arc-shaped clamping blocks 22 to change the distance between the two arc-shaped clamping blocks 22, so as to achieve precise adjustment of the diameter of the seating channel 20 to meet the use requirements of implant nails of different specifications.

[0031] Reference Figure 2 and Figure 3 As shown, the adjusting block 24 is composed of an upper conical block and a cylindrical block. The outer wall of the cylindrical block is threadedly connected to the first thread groove 211. The ends of the two arc-shaped clamping blocks 22 close to the adjusting block 24 are horn-shaped. The upper conical block on the adjusting block 24 is slidably connected to the horn-shaped inner walls at the lower ends of the two arc-shaped clamping blocks 22. The unique structure of the adjusting block 24 cooperates with the arc-shaped clamping blocks 22 to accurately adjust the diameter of the seating track 20. The outer wall of the cylindrical block cooperates with the first thread groove 211. When the adjusting block 24 is rotated, it can be stably moved along the first thread groove 211. The upper conical block is slidably connected to the horn-shaped inner wall at the lower end of the arc-shaped clamping block 22. When the adjusting block 24 moves, the upper conical block uses its own taper to push the arc-shaped clamping block 22 to move radially along the horn-shaped inner wall, thereby evenly and accurately changing the spacing between the two arc-shaped clamping blocks 22, thereby achieving fine adjustment of the diameter of the seating track 20.

[0032] Reference Figure 2 and Figure 3As shown, the inner surfaces opposite to each other of the two arc-shaped clamping blocks 22 are provided with second thread grooves 221, and the shape and size of the second thread grooves 221 match the threads of the implant nails used. During the implant nail implantation process, the second thread grooves 221 cooperate with the threads of the implant nails, so that the implant nails can accurately enter the positioning channel 20 along a predetermined direction, thereby preventing the implant nails from being offset, ensuring the accuracy and stability of the implant nail implantation, and also helping to improve the success rate of the implant surgery.

[0033] Reference Figure 1 As shown, the smooth coating 12 is made of polytetrafluoroethylene material. Polytetrafluoroethylene material has an extremely low friction coefficient, which can greatly reduce the friction of the implant nail when it moves in the positioning channel 20, making the implant nail implantation process smoother and more precise, while avoiding damage to the surface of the implant nail. Moreover, the material has high chemical stability and can maintain stable performance in the complex chemical environment of the oral cavity. It also has good biocompatibility and will not have adverse effects on oral tissues. In addition, its surface is not easy to absorb impurities, which is convenient for cleaning and maintenance, and helps to ensure the performance and service life of the positioning device.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
