Abstract

The present application relates to the technical field of medical devices, and particularly relates to a spondylolisthesis lifting tool for minimally invasive surgery. The spondylolisthesis lifting tool for minimally invasive surgery comprises a connector, a fixing sleeve and a lifting sleeve. The connector comprises a connecting rod, a first connecting mechanism and a second connecting mechanism. The first connecting mechanism and the second connecting mechanism are arranged on the connecting rod at intervals. The first connecting mechanism comprises a fixed component and a movable component. The fixed component is connected with the fixing sleeve, and the movable component is connected with the connecting rod. The movable component can rotate or be locked with the fixed component as a reference. The second connecting mechanism is installed on the connecting rod and its position on the connecting rod can be adjusted and locked. The second connecting mechanism is connected with the lifting sleeve. The present application has a reasonable structure design, is convenient to operate, and can meet all the functions required in the process of spondylolisthesis reduction.
