Description

Technical Field

[0001] The utility model relates to the technical field of oral implant auxiliary tools, in particular to a device that facilitates the reinsertion of periosteal nails. Background Art

[0002] Oral implant nails, also known as periosteal nails, bone nails, or bone nails, are an auxiliary tool used in oral implant surgery. During the process of dental implant placement after tooth loss, bone augmentation surgery, also known as guided bone regeneration (GBR), is sometimes necessary to increase the height or width of the alveolar bone to provide adequate support for the subsequent implant. During this procedure, a barrier membrane is used to separate the bone regeneration area from the oral soft tissue, preventing the soft tissue from entering the newly formed bone area and interfering with bone growth, while promoting new bone formation. To secure the barrier membrane, small nails made of titanium or other biocompatible materials are typically used. These nails are called periosteal nails. Periosteal nails help maintain the barrier membrane in place, promoting bone regeneration and repair until the bone is fully grown and stabilized. This method helps ensure sufficient healthy bone around the implant, thereby improving the success rate of dental implants.

[0003] Periosteal nails are typically provided with a nail box (such as the nail storage box disclosed in CN 219878354 U) and a nail remover. During the bone grafting procedure, the nail is removed from the nail box using the nail remover. The nail is then placed into the oral cavity and the tail of the nail remover is struck with a bone hammer to secure the nail to the alveolar bone. Periosteal nails are typically temporary and are removed and returned to the nail box after the bone heals. Currently, the nail is typically removed and placed into the nail hole of the nail box using tweezers. However, due to its small size, the nail is difficult to hold and can easily fall off during placement. Utility Model Content

DETAILED DESCRIPTION

[0025] The following is a combination of specific embodiments and appendix Figure 1-3 The utility model is described in detail so that those skilled in the art can more fully understand the purpose, features and effects of the utility model.

[0026] Unless otherwise specified, all technical and scientific terms used in this utility model have the same meanings as commonly understood by those skilled in the art to which this utility model belongs. In the event that the definition of a term in this utility model conflicts with the meaning commonly understood by those skilled in the art to which this utility model belongs, the definition in this utility model shall prevail.

[0027] The utility model provides a device that is convenient for reinserting the periosteal nail, so that the periosteal nail can be stably grasped during the reinsertion process of the nail box, thereby preventing the periosteal nail from falling off and allowing the periosteal nail to be smoothly inserted into the nail box.

[0028] Example 1

[0029] As a specific embodiment of the present invention, this embodiment provides a device that facilitates the reinsertion of the periosteal nail. Figure 1 、 Figure 2 , comprising a tube body 1. The interior of the tube body 1 is hollow, forming a lumen 11. The top end of the tube body 1 is open and detachably connected to a tube cap 12. The tube cap 12 seals the top end of the tube body 1. After the internal components are installed, the top end of the tube body 1 is sealed to prevent dust and other debris from falling in. The lower portion of the tube body 1 gradually contracts downward to form a contraction portion, and a via 14 is provided in the middle of the contraction portion. The via 14 connects the lumen 11 of the tube body 1 to the outside.

[0030] Preferably, the connection between the tube body 1 and the tube cap 12 is a threaded connection to ensure a reliable connection between the tube body 1 and the tube cap 12 .

[0031] Preferably, the tube body 1 and the lumen 11 are both circular. The circular shape of the tube body 1 facilitates gripping by the operator, improves operational comfort and stability, and also facilitates processing. Anti-slip protrusions or ridges are provided on the outer surface of the tube body 1, further improving operational stability through the anti-slip design.

[0032] The lumen 11 is sequentially arranged with the driver 3, push rod 5, and nail claw 7 from top to bottom. The push rod 5 is sleeved with a spring 6. Specifically, the push rod 5 is fixedly connected to the bottom surface of the driver 3 and has a smaller cross-section than the driver 3. Preferably, the push rod 5 is cylindrical and fixed in the middle of the bottom surface of the driver 3, opposite the through hole 14.

[0033] In another feasible embodiment, a positioning blind hole is opened on the bottom surface of the driving member 3, and the push rod 5 is inserted into the positioning blind hole of the driving member 3 to be connected to the driving member 3, wherein the positioning blind hole is located in the middle position of the bottom surface of the driving member 3.

[0034] The shape of the driving member 3 is adapted to the shape of the tubular cavity 11. In this embodiment, the driving member 3 is slidably connected to the inner wall of the tubular body 1. The driving member 3 is adapted to the tubular cavity 11 and can slide along the length direction of the tubular body 1 without moving perpendicular to the length direction of the tubular body 1.

[0035] The push rod 5 is provided with a fixed claw portion 51 at one end away from the driving member 3, and the fixed claw portion 51 is fixedly connected to the push rod 5. The nail claw 7 is fixed on the fixed claw portion 51. The specification of the fixed claw portion 51 can be larger than the size of the through hole 14, or smaller than the size of the through hole 14. When the specification of the fixed claw portion 51 is larger than the size of the through hole 14, the fixed claw portion 51 cannot extend to the outside of the tube body 1, and only the nail claw 7 is allowed to extend; when the size of the fixed claw portion 51 is smaller than the size of the through hole 14, the fixed claw portion 51 can extend to the outside of the tube body 1, and the nail claw 7 is completely pushed out. Figure 3 As shown, under the action of the push rod 5, the fixed claw portion 51 and the nail claw 7 can be pushed out of the tube body 1. Specifically, whether to allow the fixed claw portion 51 to be pushed out can be selected according to actual needs. In addition, in actual operation, the extension amount of the nail claw 7 can also be determined by controlling the push rod 5.

[0036] After the spring 6 is mounted on the push rod 5, one end of the spring 6 in the longitudinal direction abuts against the bottom surface of the driving member 3, and the other end abuts against the inner wall of the contracted portion of the tube body 1. The top end of the spring 6 is restrained by the driving member 3, and the bottom end of the spring 6 is restrained by the inner wall of the tube body 1. By moving the driving member 3 up and down, the compression amount of the spring 6 and the extension amount of the nail claw 7 outside the tube body 1 can be adjusted.

[0037] The side wall of the tube body 1 is provided with a long strip sliding window 13 along the length direction of the tube body 1, and the sliding window 13 connects the lumen 11 of the tube body 1 with the outside. The driving member 3 is connected to a sliding button 2 located outside the tube body 1. Pushing down the sliding button 2 can drive the driving member 3 to move along the length direction of the sliding window 13, and the size of the driving member 3 is larger than the width of the sliding window 13, and the driving member 3 cannot fall out of the sliding window 13. The connection between the sliding button 2 and the driving member 3 can be snap-fit, plug-in or adhesive, as long as the sliding button 2 and the driving member 3 can be stably connected. Preferably, the surface of the sliding button 2 is provided with anti-slip grooves to improve the convenience of operation. Setting the sliding button 2 on the side can enable the operator to better grip the tube body 1 and improve the stability of the operation.

[0038] By pushing downward on the sliding button 2 located outside the sliding window 13, the sliding button 2 moves away from the tube cap 12. At this time, the spring 6 mounted on the push rod 5 is compressed, and the push rod 5 simultaneously pushes downward on the nail claw 7, partially or completely extending it to the outside of the tube body 1 to grasp the periosteal nail. The downward push distance of the sliding button 2 is controlled by the operator. When the operator's finger pushing down on the sliding button 2 reduces the force, the spring 6 causes the drive member 3 to reset, and the push rod 5 drives the nail claw 7 back into the lumen 11 of the tube body 1.

[0039] Since the sliding button 2 is restricted by the upper end of the sliding window 13 , when the driving member 3 is reset, the driving member 3 cannot continue to move upward and can only be reset to its original position.

[0040] In one feasible embodiment, the sliding window 13 extends upward through the top of the tubular body 1. In this embodiment, the sliding button 2 and the driver 3 can also be integrally connected. Because the top of the sliding window 13 is open, the driver 3 can be easily installed within the lumen 11 of the tubular body 1 without restricting the sliding button 2. The integral connection between the sliding button 2 and the driver 3 improves operational stability and reliability.

[0041] In this embodiment, the sliding window 13 is longer only to facilitate the installation of the integrally connected sliding button 2 and the driving member 3. In actual operation, the lower part of the sliding window 13 is used for sliding operation. When the driving member 3 is reset, since the sliding button 2 is not restricted, the driving member 3 is prone to over-reset (over-reset) under the action of the spring 6. Therefore, an auxiliary rod 4 extending along the length direction of the tube body 1 is fixed to the top surface of the driving member 3. The length of the auxiliary rod 4 is equal to the distance between the top surface of the driving member 3 and the bottom surface of the tube cap 12 when the driving member 3 is in the normal position. Due to the existence of the auxiliary rod 4, when the driving member 3 is reset, the driving member 3 will not be over-reset due to the elastic force of the spring 6.

[0042] The nail claws 7 are composed of elastic steel wires and are retractable. There are three or four steel wires, and the steel wires are evenly arranged at equal distances along the circumference of the tube body 1. The bottom ends of the steel wires are bent inward. When not in use, the nail claws 7 are retracted in the tubular cavity 11. The steel wires cannot be unfolded due to the restriction of the inner wall of the tube body 1. When it is necessary to grab the periosteal nail, the nail claws 7 are pushed out by the push rod 5, and the steel wires gradually lose their restraint and unfold outward. When the nail claws 7 are fully pushed out, the expansion of the steel wires is the largest. Since the bottom ends of all the steel wires are bent inward, a grasping structure can be formed.

[0043] Furthermore, in order to facilitate placement when not in use, a pipe clamp is also fixed on the pipe cap 12. The device can be conveniently fixed by the pipe clamp.

[0044] Furthermore, the tube body 1 and the tube cap 12 are both made of stainless steel, thereby improving the strength of the device.

[0045] Because periosteal nails are small in size, made of pure titanium, non-magnetic, and smooth, they are prone to splashing during the grasping process. Therefore, it is necessary to ensure that the grasping is convenient and stable during the reinsertion into the nail box to prevent the periosteal nail from falling out. The device for facilitating the reinsertion of periosteal nails provided by the utility model can quickly grasp the periosteal nail and maintain stability during movement, thereby making it easier to insert the periosteal nail into the nail box, reducing the complexity of the operation and preventing damage to the periosteal nail.

[0046] Example 2

[0047] As a specific embodiment of the present invention, this embodiment provides a device that facilitates the reinsertion of periosteal nails. Figure 3 The following describes a method for using a device provided in this embodiment to facilitate reinsertion of a periosteal nail.

[0048] During use, the operator holds the tube body 1, places the thumb on the sliding button 2, and pushes down the sliding button 2. The sliding button 2 drives the driving member 3 to move downward in the tube cavity 11. The spring 6 is compressed, and the push rod 5 moves synchronously with the movement of the driving member 3, pushing the nail claw 7 to the outside of the tube body 1 to grab the periosteal nail 9, and after grabbing, the periosteal nail 9 is inserted back into the binding hole 81 of the binding box 8.

[0049] It should be noted that since the bottom end of the steel wire of the nail claw 7 is bent inward, when operating, the nail claw 7 should first be expanded to a greater extent than the head of the osteotomy nail 9, and then the sliding button 2 should be slowly released and retracted upward a small distance so that the bottom end of the steel wire of the nail claw 7 clamps the head of the osteotomy nail 9. At this time, the sliding button 2 should be kept stationary and the osteotomy nail 9 should be moved into the binding hole 81 of the binding box 8.

[0050] When the periosteum nail 9 is moved into position, the sliding button 2 is pushed down continuously to expand the extension range of the nail claw 7, and the periosteum nail 9 is separated from the nail claw 7, completing the reinsertion of the periosteum nail 9.

[0051] Afterwards, repeat the above steps to grab and move the remaining periosteal nails 9 until all periosteal nails 9 are reinserted, and then slowly loosen the sliding button 2 to reset the device.

[0052] The device for facilitating the reinsertion of the periosteal nail of the utility model has a simple structure, is easy to operate, and is easy to use. It can meet the stability requirement when reinserting the periosteal nail, and can be applied to periosteal nails of different sizes and shapes, and has a wide range of applications. In addition, it is not easy to splash when grasping, the operation is quick, and the reinsertion time is saved, thereby improving the efficiency of the reinsertion of the periosteal nail and avoiding damage to the periosteal nail caused by splashing.

[0053] The above description is merely a preferred embodiment of the present invention and does not constitute any other limitation to the present invention. Any modification or equivalent variation based on the technical essence of the present invention shall still fall within the scope of protection claimed by the present invention.
