摘要：
Disclosed is a pedicle screw structure with a balloon (9), the pedicle screw structure comprising a pedicle screw (5), the balloon (9), a balloon threaded connector (2) and a channel tube (1), wherein a front end of the channel tube (1) is fixed to the balloon threaded connector (2), and the balloon (9) is fixed to a front end of the balloon threaded connector (2)； and a fixing needle (6) is provided in the channel tube (1), passes through the pedicle screw (5) and the balloon threaded connector (2) and is inserted into a fixing head of the balloon (9) to form an alignment structure for the balloon (9). The balloon (9) is fixed onto the balloon threaded connector (2) in threaded connection with the channel tube (1) and is aligned by means of the fixing needle (6), and then, the balloon threaded connector (2) and the balloon (9) are fixed to the pedicle screw (5) by means of the cooperation of the channel tube (1), thereby realizing a better space cleaning effect and solving the problem of a silicone balloon being easily pierced. In addition, the balloon (9) can effectively limit the flow of bone cement, so that the bone cement does not flow out to come into contact with nerves, and more importantly, the circumstances, such as those where due to a poor bone density, the locked pedicle screw (5) is loose and not tightly locked and will fall off again if subjected to a severe or instantaneous major injury, are solved.L'invention concerne une structure de vis pédiculaire avec un ballonnet (9), la structure de vis pédiculaire comprenant une vis pédiculaire (5), le ballonnet (9), un raccord fileté de ballonnet (2) et un tube de canal (1), une extrémité avant du tube de canal (1) étant fixée au raccord fileté de ballonnet (2), et le ballonnet (9) étant fixé à une extrémité avant du raccord fileté de ballonnet (2)； et une aiguille de fixation (6) est disposée dans le tube de canal (1), passe à travers la vis pédiculaire (5) et le raccord fileté de ballonnet (2) et est insér
