Description
Technical Field
The invention relates to the technical field of medical instruments, in particular to a novel sliding groove pedicle screw internal fixing system.
Background
An early-onset scoliosis is a scoliotic deformity that occurs before the age of 10 and is at greater risk of progression, and although its etiology is relatively complex, it can eventually lead to the spine exhibiting severe deformity. Early-onset scoliosis is generally characterized by poor spinal development, rapid scoliosis development, involvement of scoliosis in long segments and the like, has great risk to the growth and development of children patients and even lives, and is the most intractable deformity in scoliosis. It is now common in the clinic for such patients to intervene in the early stages, generally by non-surgical treatment measures, in the further development of scoliosis, but surgical treatment is often required when non-surgical treatment fails.
The growth rod technology is a better mode in the surgical treatment of the patients, the growth rod technology is to fix the metal rod on the upper end vertebral body and the lower end vertebral body through the pedicle screws, the middle part of the metal rod realizes the sliding of the metal rod in the metal rod through the U-shaped pedicle screws which are not completely locked, and the longitudinal growth and development of the spine are maintained through the regular loosening of the connector while the scoliosis deformity is corrected. However, most of the existing pedicle screws matched with the growth rod technology are realized by improving the traditional U-shaped pedicle screws, and three important technical keys exist in clinical use, namely: firstly, most of metal bars can be bent to a certain degree according to the physiological curvature of the spine of a patient under the condition of being in the body of the patient, but most of channels for the metal bars to slide of the existing chute nail products are cylindrical channels, and when the metal bars are bent, the metal bars can be clamped and pressed in the sliding process, so that the metal bars lose the sliding function; secondly, after the vertebral pedicle screw of the spine is placed in the patient body, the vertebral spine of the patient needs to be effectively reset and corrected through the matching of the vertebral pedicle screw and the metal rod, but the current multiaxial vertebral pedicle screw which is convenient to use has poor resetting and correcting effects, so that most of the multiaxial vertebral pedicle screws are used for surgery, and the problem of inconvenient use in the surgery is also caused; third, it is often necessary to remove all of the chute screws from the patient and reinsert the fused fixation pedicle screws after the patient has been placed into the growth rod system and the treatment is finally completed. This procedure requires the patient to undergo a second total incision and replace a large number of implants, which causes secondary pain and increases the economic burden on the patient. Therefore, the three key technical problems are solved, and the key of the slide groove pedicle screw system in the growing rod technology is the further application.
