Embodiment 1

[0027] Embodiment 1: A special tool for thoracolumbar fracture repair surgery, including a repair contour fixation component and a shaped filler block 1, the repair contour fixation component is implanted into the fracture site to form a repair target contour, and the shaped filler block is inserted into the repair contour fixation component to form Stable repair filling; the repair contour fixing assembly includes at least one pair of upper fixing blocks 2 and lower fixing blocks 3, the bottom of the upper fixing block 2 is provided with a first keyway 4, the top of the lower fixing block 3 is provided with a second keyway, and the shape of the filling block 1 The top and the bottom are respectively provided with the first key body 6 matched with the key groove, and the first key body 6 on the upper and lower surfaces of the shaped filling block 1 is respectively inserted into the key groove of the upper fixed block 2 and the lower fixed block 3 to fix the upper and lower fixed...

Embodiment 2

[0035] Embodiment 2: The structure of this embodiment is basically the same as that of Embodiment 1. The difference is that the upper and lower surfaces of the shaped filling block in this structure are respectively provided with an expansion spacer 10, and the expansion spacer has the upper and lower surfaces respectively. The second key body 11 matched with the first and second key grooves on the lower fixed block and the third key groove 12 matched with the first key body on the shaped filling block, wherein the length of the expansion spacer is consistent with the shaped filling block, and the thickness is 1.5mm; the second key body is matched with the first and second key grooves; the third key groove is matched with the first key body.

[0036] The specific operation process of performing the thoracolumbar fracture repair operation using the tool of this embodiment includes the following steps:

[0037] (1) Firstly, the dilator disclosed in the patent CN1748654A needs to...

Abstract

The invention discloses a special tool for the thoracolumbar vertebral fracture repair surgery. The special tool comprises a repairing profile fixing assembly and a sizing filling block, wherein the repairing profile fixing assembly is implanted into the fracture part, so that the repairing target profile is formed, and the sizing filling block is placed into the repairing profile fixing assembly, so that the stable repairing filler is formed. The special tool provided by the invention is simple in structure and convenient for the surgical operation, the surgical time can be effectively shortened, the tool is high in structural flexibility, the size of the embedded block can be selected according to the specific condition of the fracture part, the wound face is small, and a patient recovers rapidly after being treated; the fracture vertebral reduction is satisfactory, the loading capacity of the centrum can be increased, and the fracture healing rate is improved; the occurrence of collapse in the injured scleromere sagittal plane is reduced, and the loss of the postoperative long-term correcting angle is avoided; the special tool is made of porous tantalum, so that the bone forming capacity of osteoblasts is improved.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a special tool for repairing thoracolumbar fractures by adopting the built-in method. Background technique [0002] Thoracolumbar compression fractures are multiple injuries in spinal surgery. The understanding and treatment of thoracolumbar compression fractures have always been controversial. For unstable thoracolumbar compression fractures with normal neurological function, most scholars recommend open reduction through the posterior approach of the thoracolumbar spine combined with internal fixation with pedicle screws, so as to restore the normal sequence of the spine and restore spinal stability as much as possible. With the development of a large number of such operations, some scholars have found that pedicle screw loosening, broken nails, unsatisfactory vertebral body reduction, and loss of corrected angle of vertebral body after removal of internal f...
