Description

Transpedicular positioning operation guider

[ technical field ] A method for producing a semiconductor device

The utility model relates to a medical treatment field especially relates to a through pedicle of vertebral arch location operation director.

[ background of the invention ]

Spinal disorders are caused by one or more individual vertebrae or discs that are abnormal due to disease or trauma. In these pathological situations, fusion of adjacent vertebral components can be used to restore normal vertebral function, achieve a stable state, protect neural structures, or to relieve patient discomfort. There are a variety of spinal fixation systems used to stabilize the spine to achieve bone fusion. Most of these fixation systems utilize fixation elements such as rods or plates that are connected to screws threaded into the vertebral bodies, facets or pedicles. Since the outer surface of the vertebral body is typically non-planar and the structure of the spine is relatively complex, it is important that the fixation elements (e.g., rods, plates, wires, staples, or screws) be properly aligned when they are inserted into the spine. Improper alignment may result in improper or unstable placement of the fixation elements or separation of the fixation elements. However, in practice, achieving and maintaining accurate positioning and guidance of the fixation elements has proven to be quite difficult. This complexity of positioning difficulty is further compounded by the fact that the angle of alignment of the fixation device through one vertebral body or pair of vertebral bodies, resulting from individual differences in spinal curvature and physiological anatomy, is unique for each individual.

Accordingly, there is a need for a guide system and tool for accurate placement of spinal fixation elements.

The utility model discloses it is not enough to solve prior art and research and propose.

[ Utility model ] content

The utility model aims at overcoming the shortcoming of above-mentioned prior art, provide a through pedicle of vertebral arch location operation director, can realize the accurate location and the accurate direction of vertebra operation.

The utility model discloses can realize through following technical scheme:

the utility model discloses a through pedicle of vertebral arch location operation director contains the dead lever, be equipped with the connecting hole that runs through the dead lever on the dead lever, be fixed with the supporting shoe on the dead lever, cup joint the stay tube with dead lever sliding connection on the dead lever of supporting shoe top, stay tube up end both sides all are fixed with the fixed block, two be provided with the bracing piece with fixed block sliding connection on the fixed block, bracing piece one end is fixed with the stopper, be provided with on the bracing piece other end with bracing piece threaded connection's nut, still be provided with on the bracing piece between two fixed blocks and rotate the fixed pipe of being connected with the bracing piece, be fixed with the stand pipe on the fixed pipe. During operation, a fixing hole is manually opened on the back of a patient, the bottom of the fixing rod is inserted into the fixing hole, the external thread at the bottom of the fixing rod is fixed with the spine, the supporting tube is sleeved at the top of the fixing rod, the endoscope used for operation is fixed on the guiding tube, the supporting tube is rotated and rotates around the supporting rod, thereby adjusting the position of the guide tube, confirming the proper puncture position through the endoscope, aligning the endoscope on the guide tube to the position of the puncture point of the operation, rotating the nut and the screw, fixing the fixed tube after the nut extrudes the fixed block, fixing the support tube after the screw penetrates through the support tube and extrudes the fixed rod, after the guide tube is completely fixed, the spinal puncture operation is carried out on the patient, the operation position can be accurately confirmed through the endoscope in the fixed guide tube position, thereby realize the accurate location of vertebra operation to the puncture instrument reaches the puncture point through the last through-hole of stand pipe and can realize the accurate direction of vertebra operation.

Preferably, the support tube is further provided with a screw in threaded connection with the support tube.

Compared with the prior art, the utility model has the advantages that:

the endoscope in the guide tube fixing position can accurately confirm the operation position, so that the precise positioning of the spinal surgery is realized, and the puncture tool reaches a puncture point after passing through a through hole in the guide tube, so that the precise guiding of the spinal surgery can be realized.
