Description
Technical field
This utility model relates to technical field of medical instruments, particularly relates to a kind of individuation pedicle of vertebral arch positioning guide plate.
Background technology
In the operations such as the reset for the treatment of spondylolishesis, malformation correction, generally all can adopt pedicle screw internal fixation operation, but because the intrinsic anatomical structure of pedicle of vertebral arch is comparatively narrow, and around it, adjoin the important anatomical structure such as blood vessel, nerve and spinal cord, implant pedicle screw exactly very crucial, if relatively large deviation appears in implantation position, vital tissue structure is adjoined in damage, will cause serious complication.
At present, the main method that pedicle of vertebral arch is entered to follow closely has two kinds: one is that doctor relies on image photo and personal experience to bore directly punching by medical kirschner; Another kind relies on X-ray system and leader label pin in operating room art, repeatedly makes film in art, and adjustment, so repeatedly, finally determines entry point and enter to follow closely angle.First method mainly relies on the personal experience of doctor, and operating difficulty is comparatively large, and operation risk is higher; Second method operation technique is loaded down with trivial details, and X-ray radiation quantity X is comparatively large, and in art, regulation time is long, considerably increases the infection probability of patient.
In recent years, along with the development of digital medical, 3D printing technique is that the Diagnosis and Treat of clinical disease provides individuation, the new approaches of accuracy and new method.3D prints the auxiliary pedicle screw of implanting of navigation template and has the advantages such as simple to operate, accuracy is high, X-ray radiation quantity X is little, operating time is short.
Chinese invention patent discloses No. 104983460 and discloses a kind of navigation module analogue body, and it comprises main body and is located at the grasping bar in main body, and main body is also provided with through hole, and front end and the surface of bone of main body fit tightly.But the fitting area of navigation module analogue body and surface of bone is less disclosed in foregoing invention patent, the unsteady phenomenon of laminating may be there is in art, had a strong impact on the accuracy of pedicle screw navigation module location.
Therefore, necessaryly a kind of individuation pedicle of vertebral arch positioning guide plate is provided, to overcome the defect existed in prior art.
