Description

一种折断面隐藏式复位椎弓根螺钉 One kind of fracture surface hidden reset pedicle screw

技术领域 FIELD

[0001] 本实用新型涉及一种医疗器械,更具体地说,涉及一种折断面隐藏式复位椎弓根螺钉。 [0001] The present invention relates to a medical device, and more particularly, to a fracture surface hidden reset pedicle screw.

背景技术 Background technique

[0002] 在矫形外科手术中,通过植入椎弓根螺钉或椎弓根钩来支持骨骼或其他组织,矫正变形,把组织保持在适当位置,以达到损伤或其他外科手术后的愈合,以及用于涉及矫正健康的其他目的。 [0002] In orthopedic surgery, be supported by a pedicle screw or pedicle hook bone or other tissue, to correct the deformation, the tissue is held in place, in order to achieve healing following surgery or other injury, and for other purposes relates to the correction of health. 例如:在需要矫正脊柱侧凸或脊柱其他异常弯曲或错位时,可沿着一个或多个脊柱节段嵌装固定的椎弓根钉、连接棒等构件,以便把各骨节支撑或保持在正确的位置。 For example: when required to correct scoliosis or other abnormal curvature of the spine or offset, may be fitted a fixed pedicle screw, the connecting rod or the like member along a segment of the spine more, in order to support various joints or held in the correct s position. 可将椎弓根螺钉、椎弓根钩或其他植入物固定于椎骨连接与连接构件,以便沿着脊柱固定连接构件。 Pedicle screw may be, pedicle hooks or other implant is fixed to the vertebrae connected to the connecting member along the spinal column for fixing the connecting member.

[0003] 通常,固定植入物和连接构件是分别放置的,就是说,在植入人体之前它们不是连接在一起的。 [0003] Generally, the implant is fixed and the connecting member are respectively disposed, that is, before they are implanted are not connected together. 例如,可先将椎弓根螺钉植入椎骨,把连接件放置在椎弓根螺钉上或周围,然后再将连接构件置于体内。 For example, the first vertebra pedicle screw placement, the connecting member is placed on or around the pedicle screw, and then the connecting member into the body. 可在插入连接构件前把它成型为连接所需的弯曲形状,或者可将其放置成临近脊柱后成形。 You may be inserted into the connection member before it is formed into the desired curved shape of the connection, or it may be placed near the spinal column after molding. 在分别放置连接构件和椎弓根螺钉或其他固定元件的情况下,为了进行连接,需要迫使连结构件和椎弓根螺钉相互靠近。 In the case where the connecting members are placed and pedicle screws or other securing elements, for connection, it is necessary to force the coupling member and the pedicle screw close to each other. 使连接构件和固定元件相互靠近而进行连接的过程通常称为“复位”。 The connecting member and the fixing element close to each other for connection process is commonly referred to as "reset."

[0004] 椎弓根螺钉通常有长尾、短尾之分,短尾椎弓根螺钉为普通螺钉,长尾椎弓根螺钉多用于复位,为复位椎弓根螺钉。 [0004] The pedicle screw typically has a long tail, short tail points, macaque pedicle screw as conventional screws, pedicle screws are used for long-tailed reset, reset pedicle screw. 在使用过程中长尾钉在与连接构件锁紧后需要将长尾折断,恢复普通螺钉高度。 During use requires long tail long tail nail break a connection with the lock member, the screws return to the normal height. 然而长尾部折断后,通常会留下较锋利的折断面,且折断面暴露在螺钉最上方,对人体神经刺激,肌肉损伤较大,不利于病人康复。 However, after long tail broken, often leaves a sharper fracture surface, and the fracture surface exposed screw the top on human nerve stimulation, muscle damage is large, it is not conducive to patient recovery.

实用新型内容 SUMMARY

[0005] 有鉴于此,本实用新型提供一种折断面隐藏式复位椎弓根螺钉,使折断面隐藏到光滑平面以下,减少对人体的伤害。 [0005] Accordingly, the present invention provides a fracture surface of the pedicle screw hidden reset the fracture surface to a smooth surface or less hidden, to reduce the harm to the human body.

[0006] 为实现上述目的,本实用新型提供了如下技术方案: [0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] 一种折断面隐藏式复位椎弓根螺钉,包括:钉体和钉尾; [0007] A fracture surface hidden reset pedicle screw, comprising: a nail body and a tail nail;
