Description

有带孔压板的四爪持骨器
技术领域:
本实用新型是属维持外科骨折临时稳定的医疗器械。
背景技术:
在临床骨科开放复位内固定手术中,持骨器是必备的手术器械,在治疗四肢管状骨干骨折的过程中,要采用切开复位、临时固定、折切开复位钢板螺钉或髓内钉内固定三个步骤,而使用一个临时稳定器械来维持复位后骨折端的稳定性,关系到手术成败。长期以来,骨科医生通常使用的都是三爪持骨器,狮嘴钳等器械来完成临时固定,根据BO理论,骨折的复位固定需达到稳定与局部软组织完整之间的平衡,使用三爪持骨器时,由于过分剥骨膜,甚至损伤其滋养动脉,使骨折局部血运的损伤加重,导致骨折不愈合、延迟愈合及死骨形成的发生率增加,给患者带来很大的损伤,造成极大的痛苦,狮嘴钳等其他骨折复位钳也同样具有上述弊病,并且只能维持骨折一个面的稳定,不能完全达到骨折解剖复位的要求,故需改进。
发明内容:
本实用新型的目的是使用有带孔压板的四爪持骨器,对复位后的骨折端临时稳定,使骨折达到解剖复位的要求,并减少对骨折端血运的损伤,为钢板螺钉或髓内钉的植入提供技术支持。
本实用新型的技术方案如图1所示,由直手柄1与弯手柄2通过小轴连接成手钳状,直手柄1与弯手柄2的钳部是形成椭圆形半合抱式的,各钳端部以V字形分叉,形成弧形四爪,在各个爪端又形成二尖头,总的形成纵向排列的8个尖头点。在椭圆形半合抱式钳部中间有带孔压板3,带孔压板3与连杆4成T字形万向连接,连杆4穿过固定在直手柄1上的连杆座5后固定在滑块6的一端,滑块6底部凸出与直手柄1的表面滑槽配合,滑块6的另一端与调节螺杆7连接,调节螺杆7是穿过固定在直手柄1的调节螺杆座8,其悬端用来进行调节,直手柄1与弯手柄2两手柄之间上部安有两弹簧片连接,使两手柄间有一定弹力保持位置,下部有活动拉杆9,活动拉杆9的一端通过万向接头固定在直手柄1上,另一端穿过弯手柄2由蝶形螺母10连接,用以调节与固定钳端合抱状态。
当在手术中使用时,固定了合抱位置后,调节调节螺杆7,使带孔压板3慢慢向前压紧到需手术部位,当到位后,可以进行钻孔植入螺钉等。
附图说明:
图1、有带孔压板的四爪持骨器结构示意图。
其中:1、直手柄;2、弯手柄;3、带孔压板;4、连杆;5、连杆座;6、滑块;7、调节螺杆;8、调节螺杆座;9、活动拉杆;10、蝶形螺母。
具体实施方式:
本实用新型按上述方案进行实施,在钳端部半合抱式的椭圆形其长轴是30~50毫米,短轴是20~30毫米,V字形分叉的两爪间距离是30~45毫米。
根据实际需要制成系列,供手术使用。带孔压板3是采用≠1×10×30(毫米)板材,长度方向的两端开有长10毫米宽8毫米的方孔,带孔压板3与连杆4是活动连接的,可以自由转动角度,满足手术需要。
本实用新型实现了四爪八点的持骨,加上带孔压板的压持,达到骨折复位后临时稳定的要求,为植入内固定物提供便利条件,同时使骨折局部血运的损伤减少到最低限度。省时、省力、减少手术中的暴露时间,使手术更加完美。
本实用新型结构简单、操作方便,是骨折手术中较好的器械。医疗器械企业都能投产,经济效益好。
