In order to achieve the above purpose, the invention provides the following technical scheme:
the minimally invasive posterior spinal short segment supporting system comprises a connecting rod, wherein a first directional percutaneous screw, a second directional percutaneous screw and a third directional percutaneous screw are installed on the connecting rod, the second directional percutaneous screw is installed between the first directional percutaneous screw and the third directional percutaneous screw, a sinking platform is arranged at the joint of the connecting rod and the second directional percutaneous screw, and the top surface of the sinking platform is a plane.
Preferably, the length of the sinking platform is 7-10mm, and the width of the sinking platform is 1-3 mm.
Preferably, the minimally invasive posterior spinal access short-segment support system comprises two connecting rods, two first oriented percutaneous screws, two second oriented percutaneous screws and two third oriented percutaneous screws. Two connective bars are not installed in the both sides of backbone separately, and the treatment that sets up two connective bars is better.
Preferably, the first, second and third orientated percutaneous screws form a triangle, such that the first, second and third orientated percutaneous screws are not in line but form a triangle-like shape, the triangle being more stable and thus the connection of the connector rod being more stable.
Preferably, the top of first orientation percutaneous screw, the orientation percutaneous screw of second and the orientation percutaneous screw of third all includes connector, connecting piece and latch fitting, the both sides of connector are equipped with the opening, the connective bar passes the connector, the latch fitting is close to the one end of connective bar is the plane, the inside of connector is equipped with the screw thread, the latch fitting with connector threaded connection. Be equipped with the internal thread in the connector, the latch fitting compresses tightly the connective bar in the connector with the internal thread cooperation, and the top of latch fitting is equipped with interior hexagonal or cross, can screw up the latch fitting like this through the screwdriver.
Preferably, the connecting rod is a bendable rod. The connecting rod is made of bendable medical materials, and is bent into an arc-shaped rod with radian by using rod holding forceps or other tools according to the shape of the spine of each patient.
Compared with the prior art, the invention has the beneficial effects that: the situation that the position of the connecting rod is unstable due to the fact that the universal percutaneous screws are unstable can not be caused by the fact that the three percutaneous screws on the connecting rod are designed into the directional percutaneous screws, the connecting rod is sunk to the joint of the second directional percutaneous screws, the second directional percutaneous screws are connected with the connecting rod, and the contact between the surface and the line is changed into the contact between the surface and the surface, so that the connecting rod is conveniently compressed.
