Abstract

一种脊柱滑脱整复固定器,涉及矫形用器具,其 特征是板体(1)上设有长条形通孔(2),板体(1)一端 设有条形骶骨钉(3)及骶骨板(4),板体(1)为两块,可 分别固定在脊柱骨背面两侧,本实用新型用于脊柱的 矫形,手术操作简单,板体(1)及骶骨所受的应力分 散。

Description

本实用新型属于矫形用器械,具体地说是一种脊柱滑脱整复固定器。
众所周知,用于矫正脊柱滑脱的器具主要为两片开关相同的钢板,使用时将每个钢板的一端弯曲成一定角度并对应插入骶孔内,然后用螺钉分别通过患椎椎弓根整复固定,左右对称。这种结构的固定器虽然结构较简单,但在钢板折弯处由于应力过于集中,容易使钢板折断和骶椎板骨折,同时因将钢板插入骶孔可引起骶神经损伤。
本实用新型目的在于提供一种,手术操作简单、应力分散、不引起骶神经损伤的脊柱滑脱整复固定器。
本实用新型的特征是:条形板体上设有长条形通孔,板体一端设有条形骶骨钉及骶骨板。
本实用新型使用时将两个板体上所连的骶骨钉打入骶骨内,两枚紧固螺栓穿过滑脱的椎体椎弓根,对应将两块板体固定,骶骨板压在骨体外侧面,从而使应力分散,手术操作简单,并且不能引起骶神经损伤。
本实用新型还可通过如下措施来实现,骶骨钉与板体呈一定角度。
下面结合附图通过实施例详细描述本实用新型。
图1,为本实用新型主视图。
图2,为本实用新型右视图。
图3,为本实用新型脊柱滑脱整复固定器的使用状态图。
本实用新型板体1为两块且呈长条形,由不锈钢板制成,板体1上开有条形通孔2,板体1一端加工有条形骶骨钉3和骶骨板4,本实用新型使用时,首先将骶骨钉3弯至与板体1垂直位置,然后将两块板体1的骶骨钉3在合适的位置上对应打入骶骨内,再将两枚带有沉头的螺栓5分别经椎弓根打入椎体,螺栓5穿过通孔2,最后用螺母拧紧螺栓5,从而使两块板体1紧紧地夹在脊柱骨的两侧,骶骨板4的尾端突出于骶骨钉3的折弯处,并且紧紧地贴在骨表面,从而使板体1及骶骨所受的应力分散。

Claims (2)

1、一种脊柱滑脱整复固定器,设有两个条形板体、紧固螺栓,其特征在于板体上设有长条形通孔,板体一端设有条形骶骨钉及骶骨板。
2、根据权利要求1所述脊柱滑脱整复固定器,其特征在于所说的骶骨钉与板体呈一定角度。
