Abstract

本实用新型涉及一种髓腔锉，具有本体，本体上端设有手把安装座，本体上设有切削齿；所述本体上还设有容屑槽。本实用新型髓腔锉本体上设有容屑槽，能容纳切削过程中的骨屑，使得髓腔通道内骨屑的明显减少；容屑槽为封闭的环形槽体，且与髓腔锉轴线呈45度夹角，这种设计对切削齿没有影响，设计合理；本体上部设有防旋斜面，防旋斜面上设有“T”形定位槽，使得操作更加方便、可靠，具有较高的实用性。

Description

髓腔锉
技术领域
本实用新型涉及一种医用人工关节假体置换手术器械，特别涉及一种髓腔锉。
背景技术
人工全髋关节置换术既能解除病髋疼痛，又能恢复正常关节功能，是目前治疗股骨头缺血性坏死、老年人股骨颈骨折等最有效的方法。随着新型生物医用材料的研制、假体设计的改进及外科手术的完善，人工关节置换在临床上取得了较大的进展。髋关节假体的固定有传统的骨水泥固定技术和现代的非骨水泥固定技术，非骨水泥固定型即生物固定型人工全髋，是利用假体表面的微孔层使骨组织长入，或通过假体外形上的改进使之紧密嵌入髋腔，从而达到生物学固定的目的，它需要较高的手术技巧、股骨柄假体设计制造的个体化和与之配套的器械，使股骨柄假体与患处锉修后的外形相匹配。
而股骨柄假体的植入需要使用髓腔锉扩大股骨近端髓腔，一般扩髓腔的过程是选用比模板确定的尺寸小二号的髓腔锉开始，每个髓腔锉都应该逐渐插入，通过手把安装座联接髓腔锉手把，然后使用榔头敲击髓腔锉手把尾部打击帽端锉修髓腔，在此过程中不应该使髓腔锉旋转，完成后直接使用髓腔锉手把或者髓腔锉取出器取出髓腔锉，更换大一号的髓腔锉再次重复，每个髓腔锉取出过后，都需要仔细清理髓腔通道内侧的骨屑。
现有的髓腔锉一般都具有本体，本体上端设有把手连接座和定位孔，本体上设有环形的切削齿，这种髓腔锉的缺点在于在扩髓过程中遗留在髓腔通道中的骨屑较多，需要较多精力用于骨屑的清理。
实用新型内容
本实用新型的目的在于提供一种克服上述缺点，扩髓过程中遗留在髓腔通道的骨屑较少的髓腔锉。
实现本实用新型目的的技术方案是：一种髓腔锉，具有本体，本体上端设有手把安装座，本体上设有切削齿；所述本体上还设有容屑槽。
上述髓腔锉的容屑槽为环形槽体，其环形所在平面与髓腔锉轴线之间夹角为45度。
上述髓腔锉的容屑槽为容屑槽截面形状为“V”形。
上述髓腔锉的容屑槽为本体上部设有防旋斜面，防旋斜面上设有“T”形定位槽。
本实用新型具有以下特点：(1)本实用新型髓腔锉本体上设有容屑槽，能容纳切削过程中的骨屑，使得髓腔通道内骨屑的明显减少；(2)本实用新型容屑槽为封闭的环形槽体，且与髓腔锉轴线呈45度夹角，这种设计对切削齿没有影响，设计合理；(3)本实用新型本体上部设有防旋斜面，防旋斜面上设有“T”形定位槽，使得操作更加方便、可靠，具有较高的实用性。
附图说明
为了使本实用新型的内容更容易被清楚的理解，下面根据的具体实施例并结合附图，对本实用新型作进一步详细的说明，其中
图1为本实用新型的立体示意图。
具体实施方式
(实施例1)
