Description

带推进器的推间融合器技术领域本发明涉及一种脊稚内固定装置,特别是一种椎间固定装置,具体地说, 涉及一种带推进器的推间融合器。 Between push belt pusher fusion Field The present invention relates to a spinal fixation device Wakkanai, particularly an intervertebral fixation device, and more particularly, relates to intervertebral A tape pusher cage. 背景技术应用推间融合器治疗脊柱疾病已有近20年的历史,国内外学者多年来的研究实验表明,理想的推间融合器应具有合适的自身体积(接触面积)和周壁厚度,既能提供充分的、稳定的持久支撑功能,又能提供足够的空间填充移植骨。 BACKGROUND push applications between fusion treatment of spinal disease for nearly 20 years, scholars at home and abroad over the years of research experiments show that, between the ideal of integration should have the right to push its own volume (contact area) and peripheral wall thickness, both provide sufficient, stable durable support function, but also to provide sufficient space is filled with bone graft. 常规的推间融合器如图1所示,推间融合器分别设置在推间的左右两侧。 Conventional intervertebral fusion device 1, the intervertebral cage are disposed between the left and right sides of the push. 推间融合器为一中空的立方体(方盒形)结构,其上、下表面分别与上、下终板接触,以保持推间高度,其中空部分和两推间融合器中间部分用于植骨(如图2)。 Intervertebral fusion device is a hollow cube (box-shaped) structure, which upper and lower surfaces respectively, the lower end plate contacts to maintain the intervertebral height, wherein the space between the two portions and an intermediate portion for pushing fusion implant bone (FIG. 2). 其侧壁上设置有数个孔洞,用于减少对移植骨的应力遮挡,促进推间骨融合。 Disposed on a sidewall of several holes, for reducing stress shielding of the bone graft to promote intervertebral bone fusion. 其上、下表面设计成防滑结构,增加摩擦阻力,防止推间融合器的移动。 On its lower surface designed to be anti-slip structure, increasing frictional resistance to prevent movement of intervertebral fusion device. 此外,其后侧壁上设置有孔,便于使用工具(如推进器)将其推送入推体内。 Further, after a hole is provided on the side wall, easy to use tools (e.g. thrusters) push into the push body. 在实际使用中,常规类型的推间融合器存在一些缺陷,如植入数年后出现不同程度的沉降以及骨融合率低等问题,最终导致推间高度丟失。 In actual use, the conventional types of intervertebral fusion device has some shortcomings, as well as varying degrees of bone fusion sedimentation rate and other issues after implant for several years, eventually leading to loss of height between the push. 近年的研究增加植骨面二;口植骨量将有助^解决上i;题。 Recent studies have increased bone surface two; amount of bone mouth will help solve the ^ i; title. 、 八、由于推间融合器的支撑性能与植骨面积、植骨量相互制约,有效、持久的支撑性能要求推间融合器的周壁具有一定厚度,降低推间融合器与推体终板的接触压强;而较好的植骨融合率则要求稚间融合器中空体积大,因此简单地增加中空体积或周壁厚度均不能彻底解决上述问题。 Eight, since the supporting performance intervertebral fusion device and bone area, bone quantity mutual restraint, effective, long-lasting support performance requirements intervertebral fusion peripheral wall having a thickness, reduced intervertebral cage of the push endplate the contact pressure; fusion rate and preferably between juvenile requires large volume of the hollow fusion device, thus simply increasing the wall thickness of the circumferential volume or hollow are not completely solve the problem. 发明内容本发明的目的是提供一种新型结构的稚间融合器,通过特殊的结构设计, 在保证具有稳定、持久的支撑性能的同时,最大限度地增加了植骨面积和植骨量,使植骨融合率大幅度提高,彻底解决推间融合器植入后沉降、堆间高度丟失的问题。 Object of the present invention is to provide a novel structure of a fusion between juvenile, through a special design, to ensure a stable, long-lasting performance while supporting, it maximizes the amount of bone graft and the area of ​​the fusion rate increased significantly, completely solve the intervertebral fusion implant settlement between the stack height loss problems. 此外,本发明还提供一种推进器,用于在手术中将本发明推间融合器推入推间间隙,以很好地配合本发明推间融合器的使用。 Further, the present invention provides a pusher for pushing in the operation of the present invention between the cage is pushed into a gap between the push to use a good fit between the cage push

elimination of intervertebral fusion device implanted settlement between height loss pushed the issue. 图5为本发明推进器的结构示意图。 5 is a block schematic diagram of the present invention the pusher. 具体地i兌,本发明推进器是一种用于将本发明推间融合器推入推间间隙的手术工具。 I against particular, the present invention is a pusher to push the surgical tool of the present invention, fusion between pushed into a gap between a push. 如图5所示,本发明推进器2 由依次连接的手柄23、细长状连杆22和接头21组成,接头21带有与推间融合器推进孔14内螺紋匹配的外螺紋。 5, the present invention is the handle 2 by a pusher 23 connected sequentially, the elongated rod 22 and the joint 21 composed of the joint 21 with an external thread intervertebral fusion propulsion hole 14 matching threads. 在实际使用中,通过接头21与推进孔14的螺接4吏推进器2和堆间融合器1连接成一体,实现将堆间融合器1推进推间间隙的操作。 In actual use, then 4 officials pusher screw joint 21 through the hole 14 of the propulsion cage 2 and the connection between the stack integrally, to achieve the fusion between the stack 1 is operating clearance between the push propulsion. 为了在推间融合器1被推进推间间隙的过程中封堵其側壁上的开口,本发明推进器2还设置有档板24。 To push the cage 1 between the process is advanced to push the gap between the opening in the closure sidewall thereof, the pusher 2 of the present invention is further provided with a baffle 24. 在本实施例中,档板24由边缘连接的橫板241和側板242组成,二平面垂直或接近垂直设置,所述橫板241上设置有与连杆22横截面同形状的中心孑L,并垂直套装在连杆22上,所述侧板设置在连杆22的側面,其平面平行于连杆22的轴线,并延伸出接头21。 In the present embodiment, the horizontal baffle plate 24 is connected by the edge 241 and the side plate 242 composed of two vertical or near vertical plane is provided, on the transverse plate 241 is provided with a cross-section of the link 22 with the center of the shape larvae L, and set on a vertical rod 22, the side plate disposed on the side surface of the link 22, which is a plane parallel to the axis of the link 22 and the joint 21 extends. 当推进器2与推间融合器1连接在一起时, 突出在接头21前面的侧板242正好可以封堵稚间融合器1側壁上的开口。 When the pusher 2 and the intervertebral cage 1 are joined together, projecting on the front side 242 of the joint 21 may be open on just one side wall fusion between the closure and juveniles. 由于档板24是套接在连杆22上,所以档板24可以在连杆22上转动或滑动,可十分方^更地转换遮挡方向,对左侧开口或右侧开口的推间融合器都适用.档板24可采用具有一定弹性的金属或非金属薄片,利用其弹性可较好地起到封堵开口的作用。 Since the baffle 24 is sleeved on the link 22, the baffle 24 may be rotated or slid on the link 22, may be more out of square ^ convert blocked direction, to the left or right side of the opening opening intervertebral cage applies. baffle 24 may be employed with certain elasticity or non-metallic sheet, by the elastic function as well can be plugged openings. 手术实际操作步猓可更清楚地表明推进器2的结构。 Step Guo surgical practice will be more clearly show the structure 2 of the propulsion. (1) 旋转推进器2,将接头21旋进推进孔14中,使推进器2与堆间融合器1连接成一体,并使推进器2上突出的档板24正好封堵推间融合器1 側壁上的开口,如图6所示;(2) 在推间融合器1的空腔内填充移植骨;(3) 握持推进器2,将推间融合器1推入推间间隙;(4) 旋转推进器2,将接头21从推进孔14中旋出,撤消推进器档板24对推间融合器1側壁开口的封堵。 (1) the rotary pusher 2, the joint 21 is screwed into the hole 14 advancing the stack between the pusher 2 and the cage 1 are integrally connected, and the pusher 2 just projecting sealing baffle 24 intervertebral cage an opening in the side wall, as shown in FIG. 6; (2) between the cage push cavity filling bone graft 1; (3) holding the pusher 2, push the cage 1 between the push-push gap between; (4) the rotary pusher 2, the joint 21 from unscrewing propulsion hole 14, 24 withdraw promote plugging cage 1 Holding the sidewall of the opening device bezel. 所述档板24封堵推间融合器1侧壁上开口的作用主要体现在推间融合器1被推入推间间隙前,使推间融合器1的中空部分成为封闭中空体,以利于植骨操作,并确保植骨过程中移植骨形成稳定的形态。 The baffles acting on the opening side wall 24 between the push block mainly before fusion intervertebral fusion device 1 is pushed into a gap between the push, so that the hollow portion of the intervertebral cage 1 becomes a closed hollow body, in order to facilitate grafting operation, and to ensure that the process of grafting the bone graft to form a stable shape. 实际上, 一旦堆间融合器1被推入推间间隙后,人体推间筋膜将起到维持植骨形态的作用。 In fact, once the cage 1 between the stack is pushed into a gap between the pushing, pushing between the fascia and body shape will play a role to maintain bone. 以上对本发明的技术方案进行了说明,但不以任何形式对本发明做出限制.应当指出,对本领域技术人员来说,依据本发明的指导思想还可以做出很多相关的变形和改进,但这些均将落入本发明的保护范围。 Above technical solution of the present invention have been described, but not in any way be made to limit the present invention.
