背景技术Background technique
腰椎滑脱、退行性腰椎侧弯是常见的腰椎疾病。而严重腰椎滑脱、退行性腰椎侧弯等病常伴有一侧或双侧椎间隙极度狭窄，在治疗过程中，需要将狭窄椎间隙撑大。目前，医疗行业内缺乏椎间撑开装置，从而造成狭窄锥间隙的撑开操作非常困难。因而，有必要为人们提供一种可方便地实现狭窄椎间隙撑开的椎间撑开器套件。Lumbar spondylolisthesis and degenerative lumbar scoliosis are common lumbar diseases. Severe spondylolisthesis, degenerative lumbar scoliosis and other diseases are often accompanied by extremely narrow intervertebral space on one or both sides. During the treatment process, the narrow intervertebral space needs to be enlarged. At present, there is a lack of intervertebral distraction devices in the medical industry, which makes it very difficult to distract the narrow conical space. Therefore, it is necessary to provide people with an intervertebral spacer kit that can conveniently realize the distraction of the narrow intervertebral space.

下面，结合附图以及具体实施方式，对本发明做进一步描述，以便于更清楚的理解本发明所要求保护的技术思路。In the following, the present invention will be further described in conjunction with the accompanying drawings and specific embodiments, so as to understand the technical ideas claimed in the present invention more clearly.
如图1、2所示，为本发明的椎间撑开器套件，包括若干个撑开器1，所述撑开器1均包括一体成型的撑开主体3、连接在撑开主体3后端的握柄；所述撑开主体3包括基部32、分别设置在基部32前后两端的前导向部31和后连接部33；从靠近基部32的一端至远离基部32的一端，所述前导向部31的横截面面积逐渐减小；从靠近基部32的一端至远离基部32的一端，所述后连接部33的横截面面积逐渐减小；所述握柄连接在后连接部33上；各撑开器1的基部32的厚度均不同，且若干个撑开器1的基部32的厚度d依次递增。具体的，所述基部32的横截面呈四边形，以方便于加工。As shown in Figures 1 and 2, it is the intervertebral distractor kit of the present invention, which includes several distractors 1, and the distractors 1 all include an integrally formed distracting main body 3, which is connected behind the distracting main body 3. The handle at the end; the stretching main body 3 includes a base 32, a front guide 31 and a rear connecting part 33 respectively arranged at the front and rear ends of the base 32; from an end close to the base 32 to an end far away from the base 32, the front guide The cross-sectional area of 31 gradually decreases; from one end close to the base 32 to one end away from the base 32, the cross-sectional area of the rear connecting portion 33 gradually decreases; the handle is connected to the rear connecting portion 33; each brace The thicknesses of the bases 32 of the spreaders 1 are all different, and the thickness d of the bases 32 of several spreaders 1 increases sequentially. Specifically, the cross-section of the base portion 32 is quadrangular to facilitate processing.
优选的，该若干个撑开器1的基部32的厚度以相同的公差依次递增，所述公差为2mm,且厚度最小的基部32为4mm厚。而通过采用上述结构，可合理设置逐级撑大的距离，使狭窄椎间隙能逐级均匀地撑大，以恢复椎间高度和复位滑脱椎体。进一步优选的，该椎间撑开器套件包括七个撑开器1，该七个撑开器1的基部32的厚度分别为4mm、6mm、8mm、10mm、12mm、14mm、16mm。Preferably, the thicknesses of the bases 32 of the several spreaders 1 increase sequentially with the same tolerance, the tolerance is 2 mm, and the base 32 with the smallest thickness is 4 mm thick. By adopting the above-mentioned structure, the step-by-step stretching distance can be reasonably set, so that the narrow intervertebral space can be stretched evenly step by step, so as to restore the intervertebral height and reset the spondylolisthesis. Further preferably, the set of intervertebral spreaders includes seven spreaders 1 , the thicknesses of the bases 32 of the seven spreaders 1 are 4mm, 6mm, 8mm, 10mm, 12mm, 14mm, and 16mm, respectively.
优选的，撑开主体3的棱角处均设为圆角。本发明通过合理设置后连接部33的结构，并通过结合上述结构，可避免撑开主体3在插入或退出狭窄椎间隙时损害神经根和硬膜囊。Preferably, the edges and corners of the stretching main body 3 are all set as rounded corners. In the present invention, by rationally setting the structure of the rear connecting part 33 and combining the above structures, it is possible to prevent the nerve root and dural sac from being damaged when the distracting main body 3 is inserted into or withdrawn from the narrow intervertebral space.
所述握柄大致呈“T”字形，具体的，所述握柄包括与后连接部33连接的的连杆21；所述连杆21后端的两侧均形成有持握部22，所述连杆21的后端设置为呈锥形的锤击部23。具体的，锤击部23的后表面设置为向外凸的弧面。通过利用锤击部23，可方便于使用者锤击，将撑开主体3击入椎间隙内；而通过利用持握部22，可方便于使用者持握，并便于使用者施力将撑开主体3从锥间隙拔出。The handle is roughly in the shape of a "T", specifically, the handle includes a connecting rod 21 connected to the rear connecting part 33; both sides of the rear end of the connecting rod 21 are formed with a holding part 22, the The rear end of the connecting rod 21 is configured as a tapered hammering portion 23 . Specifically, the rear surface of the hammering part 23 is configured as an outwardly convex arc surface. By using the hammering part 23, it is convenient for the user to hammer and drive the main body 3 into the intervertebral space; and by using the grip part 22, it is convenient for the user to hold it, and it is convenient for the user to apply force to push the main body 3 into the intervertebral space. The main body 3 is pulled out from the cone gap.
在实际运用时，按基部32厚度的薄至厚，可将该若干个撑开器1分为第一级撑开器(也就是基部32为4mm厚的撑开器)、第二级撑开器(也就是基部32为6mm厚的撑开器)......第n级撑开器。在使用过程中，使用者持握握柄，可先将第一级撑开器的撑开主体3插入狭窄椎间隙内，然后依顺序将第二个撑开器、第三个撑开器......第n级撑开器的撑开主体3分别插入至狭窄椎间隙内，以逐步扩大狭窄椎间隙，从而方便于实现狭窄椎间隙的撑开。且当狭窄椎间隙逐级撑开时可使椎间盘纤维环及前后纵韧带钝性松解，从而可恢复椎间高度，并使滑脱椎体复位。In actual use, according to the thickness of the base portion 32 from thin to thick, the several spreaders 1 can be divided into first-stage spreaders (that is, the base portion 32 is a 4mm thick spreader), and second-stage spreaders. (that is, the base 32 is a spreader with a thickness of 6 mm)...the nth stage spreader. During use, the user holds the handle, and can first insert the spreader main body 3 of the first-stage spreader into the narrow intervertebral space, and then insert the second spreader and the third spreader in sequence. ..... The distractor main body 3 of the nth stage distractor is respectively inserted into the narrowed intervertebral space to gradually expand the narrowed intervertebral space, so as to facilitate the distraction of the narrowed intervertebral space. And when the narrow intervertebral space is stretched step by step, the fibrous annulus of the intervertebral disc and the anterior and posterior longitudinal ligament can be bluntly released, thereby restoring the intervertebral height and resetting the spondylolisthesis.
本发明通过合理设置撑开器1的撑开主体3，可利用前导向部31，使撑开主体3顺畅地进入狭窄椎间隙内，而且，通过采用若干个撑开器，并使该若干个撑开器1的基部32的厚度依次递增，可逐步扩大狭窄椎间隙，从而可方便地实现狭窄椎间隙的撑开，同时，还可实现狭窄椎间隙的复位；此外，通过合理设置撑开主体3，还可避免拔出撑开主体3时损伤神经根，以提高使用安全性；通过合理设置握柄的结构，还方便于撑开主体3的插入和退出操作。In the present invention, by reasonably arranging the main body 3 of the spreader 1, the front guide part 31 can be used to make the main body 3 of the spreader smoothly enter the narrow intervertebral space. The thickness of the base part 32 of the spreader 1 increases successively, which can gradually expand the stenotic intervertebral space, so that the stenotic intervertebral space can be easily expanded, and at the same time, the stenotic intervertebral space can also be reset; 3. It can also avoid damage to the nerve roots when the main body 3 is pulled out, so as to improve the safety of use; by rationally setting the structure of the handle, it is also convenient for the insertion and withdrawal of the main body 3 .
上述实施方式仅为本发明的优选实施方式，不能以此来限定本发明保护的范围，本领域的技术人员在本发明的基础上所做的任何非实质性的变化及替换均属于本发明所要求保护的范围。The above-mentioned embodiment is only a preferred embodiment of the present invention, and cannot be used to limit the protection scope of the present invention. Any insubstantial changes and substitutions made by those skilled in the art on the basis of the present invention belong to the scope of the present invention. Scope of protection claimed.
