Embodiment
Embodiment of the present utility model is illustrated below in conjunction with the accompanying drawings.
Fig. 1 shows the Yong of embodiment one of the present utility model in Bao Hu popliteal tendons and the specific purpose tool of lateral collateral ligament
10.The specific purpose tool 10 is used primarily in total knee replacement.As described in Figure 1, the specific purpose tool 10 include handle 1 and with
The connected pole 2 of handle 1, and the block hook 3 of the arc being connected with pole 2.Specific purpose tool 10 is chosen as hard material and is made.It is preferred that
Ground, the material of the handle 1 of specific purpose tool 10 is resin, and the material of the block hook 3 of the material and arc of pole 2 is all stainless steel.It is excellent
Selection of land, the corner of arc bulk hook 3 is circular arc chamfering, to prevent the corner of the block hook 3 of arc from scratching tissue.
In order to promote the block hook 3 of arc matchingly to engage condylus lateralis femoris, the structural parameters of the block hook 3 of arc are carried out
Optimize below.That is, the radian of the block hook of arc is 2 π/3~5 π/6rad, and internal diameter is 10~30mm, and thickness is 1~2mm.By big
Experimental verification is measured, when the radian of the block hook of arc is 2 π/3~5 π/6rad, internal diameter is 10~30mm, when thickness is 1~2mm, the arc
Block hook 3 just can matchingly engage condylus lateralis femoris so that operative doctor is easy to insert it into condylus lateralis femoris rear portion guarantor
Hu popliteal tendons.
In order to be applicable the crowd of different heights, the radian of arc bulk hook 3 is 3 π/4rad, internal diameter be 15mm, 20mm or
25mm, thickness is 1~2mm.When the radian of the block hook 3 of arc is that 3 π/4rad, internal diameter are 15mm, thickness is 1~2mm, and the arc is block
Hook 3 exists suitable for height<160cm crowd.When the radian of the block hook 3 of arc is that 3 π/4rad, internal diameter are 20mm, thickness is 1~
2mm, arc bulk hook 3 is applied to crowd of the height between 160~175cm.When the radian of the block hook 3 of arc be 3 π/4rad, it is interior
Footpath is 25mm, and thickness is 1~2mm, and arc bulk hook 3 exists suitable for height>175cm crowd.
Pole 2 is chosen as pole, is also chosen as knee.In the embodiment shown in fig. 1, pole 2 has flat part 21
