如图13、16,肱骨干骨折的骨干内固定系统。 As shown in Figure 13, 16, humeral shaft fracture fixation system.

[0032] 植入过程:在肩峰外侧作一短切口,显露分离三角肌,暴露大结节,在其后侧钻一骨洞并扩孔;使用植入和取出装置4将第一髓内固定板I和第二髓内固定板2植入孔中,沿髓腔进入(将骨折复位)并穿过骨折线进入骨干远端,使二者在髓腔内环抱形成一个空心椭圆柱;再用手术固定装置5固定住第一髓内固定板I和第二髓内固定板2,使用植入和取出装置4将嵌入式椭圆柱3从圆孔53处插入环抱的空心椭圆柱,至第一突起11和第二突起21处,将第一髓内固定板I的远端和第二髓内固定板2的远端分开,呈“倒八字形”,嵌入式椭圆柱3进入骨干远端,三者的近端留在骨外O. 5-lcm,第一通孔12、第二通孔22和第三通孔31留在骨干外。 [0032] The implantation procedure: on the outside shoulder to make a short incision to expose the separation deltoid, exposed large nodules, on its rear side and drill a hole reaming bone; 4 will be the first use of implantation and removal of intramedullary device 2 implant I and the second mounting plate intramedullary fixation plates, along the canal to enter (the fractures) and across the fracture line into the shaft distal end, so that the two formed in the medullary cavity surrounded by a hollow oval column; then fixing means 5 is fixed with surgery with intramedullary fixation plate I live first and second intramedullary fixation plate 2, the use of implantation and removal device 4 embedded elliptical cylinder 3 is inserted from the hole 53 of the hollow oval surrounded by columns, to the first a projection 11 and the second protrusion 21, the distal end of the intramedullary fixation plate I first distal end and a second separate intramedullary fixation plate 2, was "herringbone", embedded into the backbone of the distal end of the oval cylinder 3 , three of the proximal left in the bone O. 5-lcm, the first through hole 12, the second through-hole 22 and the third through hole 31 left in the backbone outside.

[0033] 取出过程:将植入和取出装置4的连接轴41套入嵌入式椭圆柱3的第三通孔31, 利用手柄43与取出敲击点将其拔出,再将植入和取出装置4的连接轴41分别套入第一髓内固定板I和第二髓内固定板2,将其先后拔出。 [0033] removal process: the connecting shaft inserted and removed device 4 embedded elliptical cylinder 41 set into the third through-hole 3 of 31, 43 and use the handle to remove the tap point and pull it out, then inserted and removed 4 connecting shaft means 41 set into the intramedullary fixation plate I were first and second intramedullary fixation plate 2, which has pulled out.

[0034] 总之,以上所述仅为本发明的较佳实施例,凡依本发明申请专利范围所作的均等变化与修饰,皆应属本发明专利的涵盖范围。 [0034] In summary, the above-described preferred embodiments of the present invention, any application under this invention patent scope modifications and alterations made, also belong to the invention covered by this patent.
