Description

Technical Field

[0001] This utility model relates to the field of dental implant technology, specifically to a self-removing membrane staple holder. Background Technology

[0002] In the field of dental implant surgery, guided bone regeneration (GBR) is a commonly used and effective method for addressing bone defects. When patients experience bone defects due to tooth loss, fractures, or other conditions, the GBR membrane plays a crucial role. It creates a relatively closed space for bone tissue regeneration. For example, in dental implant surgery, alveolar bone is prone to resorption or insufficient bone volume after tooth extraction. The GBR membrane prevents surrounding soft tissues, such as gingiva, from growing into the defective area of ​​the alveolar bone. GBR membrane staples are then used to firmly fix the GBR membrane to the alveolar bone surface, ensuring that bone cells grow and multiply normally within the protected space, thereby increasing bone volume or repairing bone tissue, providing a good bone foundation for subsequent implant placement or orthopedic treatment.

[0003] However, numerous problems exist in the practical application of existing technologies. On one hand, when facing uneven bone surfaces, the stapler used for the membrane staple often becomes misaligned. This is because the uneven bone surface makes it difficult for the stapler to maintain a stable vertical position. As a result, during the insertion of the membrane staple, the instability of the stapler is directly transmitted to the staple, causing it to bend. This bending renders the staple unusable and unusable, increasing surgical costs and potentially delaying the surgical process.

[0004] On the other hand, another serious problem arises when membrane staples are applied to type IV bone. The membrane staples often fail to separate smoothly from the staple holder, a phenomenon that severely impacts the success of the surgical procedure. Because of this inability to separate, the membrane staples cannot be firmly fixed within the jawbone, resulting in ineffective fixation of the GBR membrane. This undermines the effectiveness of the GBR technique, negatively impacts bone tissue regeneration, and may ultimately affect the success rate of the surgery and the patient's recovery. Therefore, an improved technique is urgently needed to address these issues. Utility Model Content

[0005] In view of this, the present invention proposes a self-removing membrane screw holder to improve the stability of the membrane screw during the bone insertion process and to enable the membrane screw to be quickly separated from the holder.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A self-removing membrane staple holder includes a staple holder body, a membrane staple auxiliary retainer, a staple pusher, and a movement control component;

[0008] The main body of the nail holder is tubular in shape. A handle is provided at the top of the main body. A membrane nail clamping step is provided on the inner side of the bottom end face of the main body.

[0011] The movement control component is connected to the push rod and is used to drive the push rod to move axially along the main body of the nail holder.

[0012] To better achieve the above technical solution, optionally, there are four annular grooves, which are continuously arranged along the axial direction of the nail holder body.

[0013] Optionally, the bottom end of the retaining rod is a pointed tip.

[0014] Optionally, the bottom end of the grip bar is provided with an internal thread, the top end of the nail holder body is provided with an external thread, and the bottom end of the grip bar is threadedly connected to the top end of the nail holder body.

[0022] The beneficial effects of this utility model are:

[0023] This invention relates to a self-removing diaphragm screw holder. The diaphragm screw auxiliary retainer and the diaphragm screw together form a pentagonal positioning structure, constraining the diaphragm screw from multiple angles. During the screwing process into the bone, the diaphragm screw is subjected to a uniform and stable force, and each direction of the diaphragm screw is effectively positioned, avoiding positional deviations caused by excessive local force or external interference during hammering or other screwing operations. Furthermore, the pentagonal positioning structure ensures that the diaphragm screw is driven vertically and accurately, improving the accuracy and success rate of implantation and ensuring the stability of the entire fixation process. The addition of a push rod enables rapid separation of the diaphragm screw from the holder. After the diaphragm screw is installed, pushing the push rod quickly and smoothly separates the diaphragm screw from the holder, saving operation time and improving work efficiency.

Detailed Implementation

[0033] The technical solution of this utility model will be described in detail below with reference to the accompanying drawings and specific embodiments. Identical components are indicated by the same reference numerals.

[0034] Please see Figures 1 to 7 This utility model discloses a self-unloading membrane staple holder, including a staple holder body 10, a membrane staple auxiliary retainer 20, a pusher rod 30, and a movement control component.

[0035] like Figures 1-3 As shown, the nail holder body 10 has a tubular structure with a handle 11 at its top. Specifically, the bottom end of the handle 11 has an internal thread, and the top end of the nail holder body 10 has an external thread. The bottom end of the handle 11 is detachably connected to the top end of the nail holder body 10 via threads. The outer circumferential surface of the handle 11 has an anti-slip structure with anti-slip texture or anti-slip sleeve.

[0036] like Figures 1-4 , Figure 6 and Figure 7 As shown, the inner side of the bottom end face of the nail holder body 10 is provided with a diaphragm nail clamping step 101. The bottom end face of the nail holder body 10 is also circumferentially distributed with expansion joints 102 extending along its axial direction. Preferably, there are four expansion joints, and adjacent expansion joints are spaced 90° apart. The nail holder body 10 is made of metal with a certain elasticity. The lower end of the nail holder body 10 expands under the radial outward squeezing force of the diaphragm nail 50 by utilizing the unique elastic properties of the metal. In conjunction with the diaphragm nail clamping step 101, the diaphragm nail 50 can be clamped. The outer wall of the nail holder body 10 is provided with a plurality of annular grooves 103 in the axial direction. Specifically, there are four annular grooves 103, which are continuously arranged along the axial direction of the nail holder body 10.

[0037] Specifically, the outer diameter of the cap at the upper end of the diaphragm nail 50 is slightly larger than the inner diameter of the diaphragm nail clamping step 101 of the nail holder body 10. When clamping the diaphragm nail 50, the lower end of the nail holder body 10 is squeezed outward by the cap at the upper end of the diaphragm nail 50, which increases the lower end aperture of the nail holder body 10. This causes the diaphragm nail 50 to move upward and get stuck on the diaphragm nail clamping step 101. When the diaphragm nail is disengaged from the lower end of the nail holder body 10, the lower end of the nail holder body 10 automatically returns to its original position due to its own elasticity.

[0038] In an embodiment of this utility model, a guide flare 105 is provided on the inner side of the lower end face of the nail holder body 10. The inner diameter of the guide flare gradually decreases from the lower end to the upper end, and the inner diameter of the lower end of the guide flare is larger than the diameter of the upper cap of the membrane nail. This helps the membrane nail 50 to quickly snap into the lower end of the nail holder body 10.

[0039] like Figure 1 as well as Figures 3-5As shown, the membrane staple auxiliary retainer 20 includes a ring 21 and retention rods 22 evenly distributed around the bottom surface of the ring 21 and extending axially thereon. The ring 21 is fitted in each annular groove 103 in a manner that moves axially along the staple holder body 10. Specifically, the membrane staple auxiliary retainer 20 is made of metal, and the bottom end of the retention rod 22 is a pointed tip so as to press against the tooth body. The ring 21 is fitted in each annular groove 103 in a manner that moves axially along the staple holder body 10, that is, the ring 21 can move up and down between each annular groove 103.

[0040] like Figure 3 , Figure 6 as well as Figure 7 As shown, the push rod 30 is disposed in the nail holder body 10 in such a way that it moves along the axial direction of the nail holder body 10. The bottom end of the push rod 30 is provided with a push part 301, which has a tapered diameter reduction structure. The push part 301 moves with the push rod 30 to disengage from / push the membrane nail 50 on the membrane nail clamping step 101.

[0041] In this embodiment, the movement control component includes a magnet 41 and a pressing part 42. The push rod 30 is made of a magnetic material. Specifically, the push rod 30 is made of magnetic stainless steel. The magnet 41 is embedded in the bottom of the hand grip 11, and the magnet 41 and the push rod 30 are attracted to each other.

[0042] like Figure 3 As shown, the upper part of the push rod 30 has a first inclined push surface 303, the pressing part 42 radially moves through the nail holder body 10, and the end of the pressing part 42 located inside the nail holder body 10 is provided with a second inclined push surface 421. The second inclined push surface 421 slides and fits against the first inclined push surface 303. The pressing part 42 can use the second inclined push surface 421 to push the first inclined push surface 303 downward, thereby driving the push rod 30 downward.

[0043] like Figure 4 As shown, in this embodiment, a limiting sleeve 12 is provided on the outer wall of the nail holder body 10 around the penetration point of the pressing part 42. The pressing part 42 slides through the limiting sleeve 12. The limiting sleeve 12 can prevent the pressing part 42 from detaching from the nail holder body 10.

[0044] like Figure 3 and Figure 4 As shown, in this embodiment, the upper inner wall of the nail holder body 10 is provided with a plurality of anti-rotation protrusions 104 extending axially at intervals in the circumferential direction, and the outer wall of the pusher rod 30 is provided with a plurality of anti-rotation grooves 302 extending axially at intervals in the circumferential direction. The anti-rotation protrusions 104 and the anti-rotation grooves 302 slide and cooperate vertically. Specifically, there are three anti-rotation protrusions 104 and three anti-rotation grooves 302, which are spaced apart. The anti-rotation protrusions 104 and the anti-rotation grooves 302 can prevent circumferential rotation during the vertical movement of the pusher rod 30, thereby ensuring the precise vertical movement of the pusher rod 30.

[0045] The working principle of the self-removing diaphragm staple holder of this utility model embodiment is as follows: The unique metallic elasticity of the staple holder body 10 is used to clamp the diaphragm staple on the diaphragm staple clamping step 101. The ring 21 is placed in the lowest annular groove 103. At this time, the fixation rod 22 protrudes about 5mm from the bottom end face of the staple holder body 10. The tip of the diaphragm staple and the tips of the four fixation rods 22 together form a pentagonal positioning structure. Then, the top of the hand grip 11 is tapped. After the diaphragm staple auxiliary fixation device 20 is subjected to force, it moves upward into the middle and upper annular grooves 103, making room. The diaphragm staple is then successfully driven into the bone. At this time, the pressing part 42 is pressed, and the push rod 30 moves downward, causing the diaphragm staple to separate from the staple holder body 10. The pressing part 42 is released. Under the action of the magnet 41, the push rod 30 moves upward and causes the pressing part 42 to reset. The top of the push rod 30 is attracted to the magnet, and the diaphragm staple fixation process is completed.

[0046] The technical solution of this utility model has been described in detail above with reference to specific embodiments. The specific embodiments described are used to help understand the concept of this utility model. Derivations and modifications made by those skilled in the art based on the specific embodiments of this utility model also fall within the protection scope of this utility model.
