Abstract

The invention provides an auxiliary expandable hemostatic conical device of a percutaneous pedicle screw. The auxiliary expandable hemostatic conical device comprises a hollow spiral device, which isintegrally formed by a head part, a body part and a tail part; a hollow part penetrates through the head part, the body part and the tail part; the head part is of a disc-shaped structure; the body part is of a conical spiral structure; and the tail part is of a conical structure. The device is used for solving the problem of extensive bleeding in a screw path of the percutaneous pedicle screw, and can be placed into an incision along the full length of a guide wire in the process of treating thoracolumbar fracture by applying a percutaneous pedicle screw technology, so that the effect of instant compression hemostasis is achieved, and the safety of an operation is greatly improved.

Description

technical field [0001] The invention belongs to the field of spinal minimally invasive technology, and relates to percutaneous pedicle screw technology, in particular to a percutaneous pedicle screw assisted expandable hemostatic cone device. Background technique [0002] Percutaneous pedicle screw technology is currently one of the most popular spinal minimally invasive techniques. In addition to being widely used in thoracolumbar fractures, it is also gradually applied to the minimally invasive treatment of degenerative diseases, especially combined with the current gradual advancement of spinal robots. This technology can be better promoted, but there is still no better way to deal with the extensive bleeding of the puncture route. Regardless of whether C-arm fluoroscopy or robot-assisted positioning is used, the skin incision is about 1 cm long, and the skin and subcutaneous tissue , deep fascia and muscle tissue all have the possibility of a large amount of bleeding, th...
