The embodiment of the invention discloses a thoracolumbar percutaneous puncture device and a method for using the same. The thoracolumbar percutaneous puncture device includes a soft tissue puncture needle, a bone puncture needle outer sleeve and a bone puncture needle inner core. The operator inserts the soft tissue puncture needle into the pedicle bone, and then uses the soft tissue puncture needle as a guide needle to insert the outer sleeve of the bone puncture needle into the pedicle bone. Pull out the soft tissue puncture needle, and insert the inner core of the bone puncture needle into the pedicle bone along the outer sleeve of the bone puncture needle. The inner core of the bone puncture needle takes the direction of the soft tissue puncture needle in the pedicle as the puncture direction, which can ensure accurate positioning of the thoracolumbar percutaneous puncture device and improve the quality of operation completion. The soft tissue puncture needle has no handle, which is conducive to the accurate positioning of the thoracolumbar percutaneous puncture device, and also avoids multiple puncture positioning processes after one inaccurate positioning, and reduces the exposure time of the operator under the transmitted radiation.
Description
technical field [0001] The invention relates to the technical field of medical devices, in particular to a thoracolumbar percutaneous puncture device and a method for using the same. Background technique [0002] Thoracolumbar fracture refers to the destruction of thoracolumbar bone continuity due to external force, which is a common spinal injury. Clinically, minimally invasive surgery is often used to treat patients with thoracolumbar fractures. The existing minimally invasive surgical methods for the treatment of thoracolumbar fractures mainly include thoracolumbar percutaneous pedicle screw placement and percutaneous balloon expansion vertebroplasty. Method of use Puncture the pedicle or place the pedicle screw into the patient's pedicle. [0003] Compared with open surgery, the use of thoracolumbar percutaneous puncture device under minimally invasive surgery has a smaller surgical opening, so it lacks the pedicle bony landmarks exposed in open surgery. Therefore, in...
