椎体后凸成形-胸腰椎系统

适用于椎体后凸成形（PKP）手术中穿刺定位、建立工作通道和预置空腔、以及推注骨水泥。

该方案可先使用3.0/3.75mm穿刺针穿刺定位，然后通过导丝更换成3.75/4.0mm扩张套件，使用3.0/3.4mm钻头建立工作通道，使用相应规格的扩张球囊及压力泵撑开复位椎体高度，预置空腔，配合1.0/1.5ml骨水泥推杆推注骨水泥。

Suitable for puncture site localization, establishment of working channels, cavity creation, and bone cement injection during Percutaneous Kyphoplasty (PKP) procedures.

The system can be punctured with the 3.0/3.75mm puncture needle for positioning, and then replaced with the 3.75/4.0mm dilator through guide wire, and the working channel is established with the 3.0/3.4mm drill bit, and using corresponding specifications of the expandable balloon and pressure pump to expand and restore the height of the vertebral body, pre-set the cavity, and then cooperate with the 1.0/1.5ml bone cement push rod to inject the bone cement.
