Description
说 明 书 一种口腔种植体携带扳手 Description A dental implant carrying wrench
技术领域 Technical field
本实用新型涉及牙科医学技术领域，具体地说是在口腔种植手术 中使用的一种口腔种植体携带扳手。 The utility model relates to the technical field of dental medicine, in particular to an oral implant carrying wrench used in oral implant surgery.
背景技术 Background technique
建立在钛金属骨结合理论基础之上的现代口腔种植义齿技术， 自 上世纪 60年代被发明以来， 不仅在临床上得到广泛应用， 而且随着 科技的发展， 种植体本身在不断改进 （例如： 中国专利 201020249801.9 ) , 手术器材和携带部件也在更新， 手术过程更加规 范。为方便医生操作和手术安全， 很多种植体上都携带按装有一个可 拆卸的零部件， 与种植体以螺丝固定在一起， 用于对种植体手术过程 进行操作， 例如从灭菌包装中取出送到受术患者的口腔中、通过扳手 来操纵旋转种植体以便植入骨内等， 这个零部件一般叫做 "携带体"。 由于种植体表面往往经过特殊处理， 不能够受到污染， 在手术植入颌 骨之前不能够接触任何物体， 只可接触钛。 因此， 为安全起见， 携带 体也往往以钛来制造， 换言之种植体附设钛金属携带体是必要的。而 有了携带体， 还需要有携带体专用扳手， 用于操纵、旋转携带体进而 操作种植体植入术。 当将种植体植入颌骨到位后， 就将携带体拆下报 废。 另外， 种植体扳手， 即直接操纵种植体的扳手， 不一定与携带体 扳手一致。 种植体扳手也可以称为 "种植体直接扳手"， 即直接操纵 种植体而不需要借助于携带体。种植体扳手是在植入后如果发现种植 体植入太深或太浅且携带体己卸除时使用。此时将其直接插入到种植 体中来操纵旋转种植体， 因此， 是校正种植体深度的必要工具。这样 一来，如果携带体扳手与种植体直接扳手不一致，扳手数量就增加了，
即要有携带体扳手， 也需要有种植体直接扳手。 目前很多流行的牙种 植体不仅都带有一次性使用的金属携带体，还配备有携带体的拆卸工 具和种植体直接扳手等工具。 现有技术的不足之处是： 1、 携带体的 拆卸操作增加了手术医生的负担和受术患者的痛苦、 延长了手术时 间； 2、 携带体钛金属材料的一次性使用和报废， 增加了材料和手术 成本； 3、 手术附件工具 （扳手） 较多， 增加了手术的烦琐程度。 实用新型内容 Modern oral implant denture technology based on titanium osseointegration theory has not only been widely used clinically since its invention in the 1960s, but with the development of technology, the implant itself is constantly improving (for example: Chinese patent 201020249801.9 ) , surgical equipment and carrying parts are also being updated, and the surgical procedure is more standardized. To facilitate the operation of the doctor and the safety of the operation, many implants are carried with a detachable component that is screwed together with the implant for manipulation of the implant procedure, such as removal from a sterile package. It is sent to the oral cavity of the patient, and the rotating implant is manipulated by a wrench to be implanted into the bone. This component is generally called a "carrier." Because the implant surface is often specially treated and cannot be contaminated, it is not accessible to any object before surgical implantation of the jaw bone. Therefore, for safety reasons, the carrier is also often made of titanium, in other words, it is necessary to attach the titanium carrier to the implant. With the carrier, a special wrench for the carrier is needed for manipulating and rotating the carrier and then operating the implant. When the implant is implanted into the jaw bone, the carrier is removed and scrapped. In addition, the implant wrench, the wrench that directly manipulates the implant, does not necessarily match the carrier wrench. The implant wrench can also be referred to as an "implant direct wrench", ie the implant is directly manipulated without the aid of a carrier. The implant wrench is used after implantation if the implant is found to be too deep or too shallow and the carrier has been removed. At this point it is inserted directly into the implant to manipulate the rotating implant and, therefore, is a necessary tool to correct the depth of the implant. In this way, if the carrier wrench is inconsistent with the implant's direct wrench, the number of wrenches will increase. In order to have a carrier wrench, you also need a direct implant wrench. At present, many popular dental implants not only have a single-use metal carrier, but also are equipped with a removal tool for the carrier and a direct wrench for the implant. The shortcomings of the prior art are as follows: 1. The disassembly operation of the carrier increases the burden on the surgeon and the pain of the patient, and prolongs the operation time; 2. The one-time use and scrap of the carrier titanium metal material is increased. Materials and surgery costs; 3, surgical attachment tools (wrench) more, increased the cumbersome degree of surgery.

实施例一、 附图为本装置的一种实施例， 下面结合附图详细加以 说明。 The first embodiment and the drawing are an embodiment of the device, which will be described in detail below with reference to the accompanying drawings.
与本装置相匹配的种植体 4为微锥形的圆柱体， 内腔中空、 内腔 壁 41上设有凸键 42， 并在内腔中部设有环形圆弧槽 43。本装置设置 为圆柱体形、 螺杆状， 由桩部 1、 杆部 2和头部 3三段式组成， 杆部 2直径与种植体 4直径一致， 头部 3直径 种植体 4内腔直径， 头部 3设有与种植体 4内腔壁 41上的凸键 42相匹配的键槽 31，头部 3前 端设置有与种植体 4内腔中部的环形圆弧槽 43相匹配的环形圆弧凸 32， 头部 3前端设置有中心孔 33和径向槽 34。
本装置头部 3上设有 2-5个键槽 31， 与种植体 4内部凸键 42相 配合， 且键槽 31数量与种植体 4内部凸键 42数量一致， 或为凸键 42数的整数倍， 但是， 键槽 31数不可能无限增大， 它将受携带扳手 头部 3圆柱形表面积及其他一些因素的限制， 例如， 若种植体 4内有 2个间隔 180度的凸键 42， 则携带扳手上就可以有 2个 （1倍， 相隔 180度） 或 4个 （2倍， 间隔 90度） 数量的键槽 31， 当为 4个键槽 31时， 扳手就可以有 4种位置插入种植体 4中， 彼此相差 90度， 携 带扳手头部 3还设有环形圆弧凸 32， 并有中心孔 33， 且被若干径向 槽 34分割成几个相等的部分， 呈多卡爪状， 典型地。 若是设置 2个 径向槽 34则环形圆弧凸 32被分割成两部分， 若是设置 4个径向槽 34， 则环形圆弧凸 32被十字形径向槽 34分割成相等的 4部分， 呈 4 个卡爪状， 将环形圆弧凸 32分割成 3等份也是另一典型情况。 设径 向槽 34和中心孔 33是为了使环形圆弧凸 32卡爪能获得弹性位移。 因此， 当将扳手的头部 3插入种植体 4内腔时， 这些卡爪会向中心做 少许弹性移动， 以便进入环形圆弧槽 43中后复位卡住种植体 4， 当 将扳手的头部 3拔出时， 环形圆弧凸 32卡爪也会做弹性径向位移缩 小直径以便从环形圆弧槽 43中退出， 退出后即恢复原状， 故环形圆 弧槽 43的深度与圆弧凸 32的凸起量可决定卡爪对种植体 4的夹持力 大小。而桩部 1设置为六方形或其他形式的旋钮状供手动操作， 或是 设置为可以便接其他扭力工具形式。 The implant 4 matched with the device is a micro-tapered cylinder, the inner cavity is hollow, the inner wall 41 is provided with a convex key 42, and an annular circular arc groove 43 is provided in the middle of the inner cavity. The device is arranged in a cylindrical shape and a screw shape, and is composed of a pile portion 1, a rod portion 2 and a head portion 3, the diameter of the rod portion 2 is the same as the diameter of the implant body 4, and the diameter of the head portion 3 is the diameter of the lumen of the implant 4, the head The portion 3 is provided with a keyway 31 matching the convex key 42 on the inner cavity wall 41 of the implant 4. The front end of the head 3 is provided with an annular circular arc 32 matching the annular circular arc groove 43 in the middle of the inner cavity of the implant 4. The front end of the head 3 is provided with a center hole 33 and a radial groove 34. The head 3 of the device is provided with 2-5 key grooves 31, which cooperate with the internal convex keys 42 of the implant 4, and the number of the key grooves 31 is the same as the number of the convex keys 42 of the implant 4, or is an integral multiple of the number of the convex keys 42. However, the number of keyways 31 cannot be increased indefinitely, and it will be limited by the cylindrical surface area of the carrying wrench head 3 and other factors, for example, if there are two convex keys 42 separated by 180 degrees in the implant 4, The wrench can have 2 (1 times, 180 degrees apart) or 4 (2 times, 90 degrees apart) number of keyways 31. When there are 4 keyways 31, the wrench can be inserted into the implant 4 in 4 positions. In the middle, 90 degrees apart from each other, the carrying wrench head 3 is further provided with an annular circular arc 32 and has a central hole 33, and is divided into several equal portions by a plurality of radial grooves 34, which are in the shape of a multi-claw, typically . If two radial grooves 34 are provided, the annular circular arc 32 is divided into two parts. If four radial grooves 34 are provided, the circular circular convex portion 32 is divided into four equal parts by the cross-shaped radial grooves 34. In the case of 4 claws, dividing the circular arc projection 32 into 3 equal parts is another typical case. The radial groove 34 and the central hole 33 are provided in order to obtain elastic displacement of the annular arcuate cam 32. Therefore, when the head 3 of the wrench is inserted into the lumen of the implant 4, the claws will move a little elastically toward the center, so as to enter the circular arc groove 43 and then reset to clamp the implant 4, when the head of the wrench is When the 3 is pulled out, the circular arc cam 32 will also be elastically radially displaced to reduce the diameter to withdraw from the circular arc groove 43 and return to the original shape after exiting, so the depth of the circular arc groove 43 and the circular arc 32 The amount of protrusion determines the amount of clamping force of the jaws to the implant 4. The pile 1 is set to a hexagonal or other form of knob for manual operation, or is set to be in the form of other torque tools.
本实用新型中，与种植体携带扳手相配合的种植体 4的内部圆柱 空腔壁 41上设有均匀分布的 2-5个凸键 42， 这些凸键将与种植体携 带扳手头部 3上的键槽 31相配合， 用于驱动种植体旋转， 也用于与 基台配合后基台的抗旋转和圆周向定位， 在种植体 4 内腔中部凸键 42以下位置， 还设有环形圆弧槽 43， 此环形圆弧槽将与种植体扳手 头部 3上的环形圆弧凸 32相配合， 携带扳手的弹性圆弧凸卡爪可进
入到此圆弧槽中， 即可拾取和携带种植体。 In the utility model, the inner cylindrical cavity wall 41 of the implant 4 matched with the implant carrying wrench is provided with evenly distributed 2-5 convex keys 42 which will carry the wrench head 3 with the implant.
