本发明提供的骨科手术用的多功能推拉勾的工作原理如下：The working principle of the multifunctional push-pull hook for orthopedic surgery provided by the present invention is as follows:

使用时，手持推柄1将推头2置于伤口内的骨头处，在推送中推头2将骨头与软组织分开，在需要调节软组织牵开的程度时首先一手指拉住副拉环18，副拉环18在拉动时带动滑片16沿连接杆12滑动，此时滑片16带动拉线17滑动，拉线17拉动第二支脚片5偏转，第二支脚片5沿第二导向杆14滑动时对第二弹簧15进行压缩，第二支脚片5在偏转同时将软组织继续扒开；When in use, hold thepush handle 1 and place thepusher 2 at the bone in the wound, and during the push, thepusher 2 separates the bone from the soft tissue. When the degree of retraction of the soft tissue needs to be adjusted, first pull theauxiliary pull ring 18 with one finger, Theauxiliary pull ring 18 drives thesliding piece 16 to slide along the connectingrod 12 when it is pulled. At this time, thesliding piece 16 drives thepull wire 17 to slide, and thepull wire 17 pulls thesecond leg piece 5 to deflect. When thesecond leg piece 5 slides along thesecond guide rod 14 Thesecond spring 15 is compressed, and thesecond leg piece 5 continues to open the soft tissue while deflecting;

随后一手指扣动主拉环13，主拉环13在拉动时副拉环18同步移动，主拉环13带动连接杆12和第一支脚片4滑动，软组织牵开件3同步滑动带动软组织进一步拉开，此时第一弹簧11被压缩，撑开组织后即可进行手术，撑开组件依靠推头2和软组织牵开件3，阻隔软组织面积较大，阻隔清晰，便于手术区清晰操作；Then one finger pulls themain pull ring 13, theauxiliary pull ring 18 moves synchronously when themain pull ring 13 is pulled, themain pull ring 13 drives the connectingrod 12 and thefirst leg piece 4 to slide, and thesoft tissue retractor 3 slides synchronously to drive the soft tissue to further Pulled open, thefirst spring 11 is compressed at this time, and the operation can be performed after the tissue is stretched. The stretcher assembly relies on thepusher 2 and thesoft tissue retractor 3, which blocks the soft tissue with a large area and clear blocking, which is convenient for clear operation in the operating area;

在操作前还可根据需要更换不同尺寸和弯曲度的推头2，在更换推头2时只需转动推头2，推柄1保持固定，此时固定块9与螺纹杆8相互分离即可更换新的推头2。Before the operation, you can also replace thepush head 2 with different sizes and curvatures as needed. When replacing thepush head 2, you only need to turn thepush head 2, and the push handle 1 remains fixed. At this time, the fixedblock 9 and the threadedrod 8 can be separated from each other. Replace thepusher 2 with a new one.

本发明提供一种骨科手术用的多功能推拉勾，通过推柄1上的推头2能够将骨头与软组织进行分开，软组织牵开件3能够对软组织进行扣合拉伸，可调节软组织的撑开尺寸，使用灵活，通过软组织牵开件3上的第一支脚片4和第二支脚片5能够对软组织进行扒住，可调节角度的第二支脚片5能够在软组织进入时更易导入，在导入后和进行箍紧，通过操作机构中的主牵拉机构作为软组织牵开件3滑动的主要组件，使软组织牵开件3整体滑动对软组织撑开，通过副牵拉机构能够使第二支脚片5偏转移动，从而对软组织进行固定，使用灵活。The present invention provides a multifunctional push-pull hook for orthopedic surgery. Thepusher 2 on the push handle 1 can separate the bone from the soft tissue, and thesoft tissue retractor 3 can buckle and stretch the soft tissue, and can adjust the support of the soft tissue. Open size, flexible use, the soft tissue can be grasped by thefirst leg piece 4 and thesecond leg piece 5 on thesoft tissue retractor 3, and thesecond leg piece 5 with an adjustable angle can be easily introduced when the soft tissue enters, After introduction and tightening, the main pulling mechanism in the operating mechanism is used as the main component for the sliding of thesoft tissue retractor 3, so that thesoft tissue retractor 3 slides as a whole to stretch the soft tissue, and the secondary pulling mechanism can make the second leg Thesheet 5 is deflected and moved, so as to fix the soft tissue and use it flexibly.
