Abstract

Provided are a thoracolumbar pedicle puncture needle and a thoracolumbar pedicle puncture kit. The thoracolumbar pedicle puncture needle comprises a needle main body, the needle main body comprises a main body section and a puncture section which are connected, the puncture section is provided with a puncture tip far away from the main body section, the puncture tip is arranged away from the axis of the main body section, and the peripheral surface of the puncture section is arranged to be an arc-shaped convex surface. In the puncture process, when the peripheral face of the puncture section makes contact with the hard cortical bone on the inner side of the vertebral pedicle, the puncture direction of the puncture needle can be changed without puncturing the cortical bone on the inner side, damage to tissues such as nerves is reduced, and therefore the safety of the puncture process is improved. Meanwhile, the arc-shaped convex surface has the function of guiding the puncture needle, so that the hand feeling of an operator in the puncture process is improved, and the puncture operation is facilitated.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a thoracolumbar pedicle puncture needle and a thoracolumbar pedicle puncture set. 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. The tail end of the puncture needle of the existing thoracolumbar percutaneous puncture device is provided with a handle, so that the operator can hold the handle to operate the thoracolumbar percutaneous puncture device during operation....
