Vertebral column resetting device

Abstract

The invention discloses a vertebral column resetting device, which comprises resetting bars, a first locking device, a vertebral arch pedicle nail and a second locking device, wherein the resetting bars are connected with the vertebral arch pedicle nail through the second locking device. The vertebral column resetting device is characterized in that: the number of the resetting bars is two; one end of one of the two resetting bars is provided with an accommodating port, the opening of the accommodating port faces the outer side of the resetting bar along the axial direction of the resetting bar, and the side wall of the accommodating port is provided with a first through hole; one end of the other one of the two resetting bars is provided with an accommodated rod, and the accommodated rod is matched with the accommodating port and provided with a second through hole communicated with the first through hole; a pin shaft passing through the first through hole and the second through hole is arranged in the first through hole and the second through hole; and the relative positions of the accommodating port and the accommodated rod are locked through the first locking device. The vertebral column resetting device is simple to operate, is not easy to cause resetting loss during operating, and has good resetting effect.

Description

spinal reduction device technical field The invention relates to the technical field of medical instruments, in particular to a spinal reset device. Background technique The spine is the pillar of the body, located in the middle of the back, as the central axis of the human body, it has the functions of weight bearing, shock absorption, protection and exercise, etc. Once the spine is fractured, serious problems will occur. Body reduction and fixation are particularly important; the spinal reset device is produced to achieve the reduction and fixation of the cone. Please refer to Figures 1 to 3, Figure 1 is a schematic structural view of a typical spinal reset device in the prior art, Figure 2 is an exploded view of a part of the structure of the spinal reset device shown in Figure 1; Figure 3 is the structure shown in Figure 1 Side view of the spinal reduction device. As shown in Figure 1, the spinal repositioning device of the prior art comprises pedicle screw 11, adj...

AI Technical Summary

Problems solved by technology

However, it can be seen from the above that the use process of the spinal reduction device in the prior art is cumbersome and the operation process is very complicated, which prolongs the time taken for the treatment; After the inclination of the nail 11, when using the adjusting locking device to lock, one of the pedicle screws 11 needs to be released, and the adjusting locking device is always set on the part of the pedicle screw that is not nailed into the inside of the spine. When the pedicle screw 11 is opened, there is no space for the support device to keep the inclination angle of the pedicle screw 11 unchanged, so that under the force of the spine, when the pedicle screw 11 is released and the lock nut 13 is not locked In some cases, the pedicle screw 11 will produce a certain loss of reduction, which affects the reduction effect
