Problems solved by technology

[0004] However, when implementing minimally invasive pedicle screw fixation, the pedicle screw fixator generally needs to adapt to the anatomical structure of the human body, while the structure of the traditional pedicle screw fixator is relatively fixed, resulting in its placement position and placement Angle adjustments are relatively fixed, not flexible enough to adapt to different anatomical structures of the human body, and may not be able to achieve the best therapeutic effect

Abstract

The invention provides a connection adapter for pedicle screws. The connection adapter is used for connecting pedicle screws (8) with a connector (4). The connection adapter (6) comprises an adapter main body part (61), a mating connecting part (62) is formed in the adapter main body part (61) and used for matching and connecting with at least one part of the connector (4); the connection adapter further comprises a mobile head (64), the mobile head (64) is used for matching and connecting with the pedicle screws (8), the mating connecting part (62) comprises a mating jack (621) formed in the adapter main body part (61), the mating jack (621) is used for matching and receiving at least one portion of the connector (4), a mobile head jack (611) for receiving the mobile head (64) is formed in the adapter main body part (61), and the extension direction of the mobile head jack (611) is perpendicular to the axial direction of the mating jack (621). The invention further provides a fixing system for pedicle screws.

Description

technical field [0001] The present disclosure relates to the field of medical devices, in particular, to a connection adapter for pedicle screws and a pedicle screw fixation system. Background technique [0002] In spinal surgery, pedicle screw is widely used as a mature surgical device. In particular, the minimally invasive pedicle screw fixation technique developed rapidly in recent years has been widely used all over the world due to its small trauma and definite effect. In the treatment of spinal injuries and fractures, the main function of minimally invasive pedicle screws is to perform spinal reduction, stabilize the dynamic segments of the spine, and promote fusion of related segments. Bone grafting to achieve effective treatment of spinal injuries and fractures. [0003] In a traditional pedicle screw fixator, a plurality of universal pedicle screws can be arranged on the fixation rod of the fixer, and the two fixation rods provided with the pedicle screws are conn...
