Embodiment 1

[0019] The soft tissue protector for spinal pedicle screw placement of the present invention comprises a half-open sleeve 1 and a holding mechanism 2, the head of the half-open sleeve 1 is open, and one side of the cylinder wall is provided with a long sleeve along the length direction of the sleeve. The strip-shaped gap 3, the strip-shaped gap 3 communicates with the opening of the head end of the semi-open sleeve 1, and the diameter of the opening of the head end of the semi-open sleeve 1 matches the diameter of the tail of the pedicle screw 4, so that the vertebral arch The 4 nail tails of a screw can just be inserted into the head end of the half-open casing 1; The holding mechanism 2 is symmetrically fixed on both sides of the tail end of the semi-open casing 1 .

[0020] The semi-open sleeve 1 is provided with a semi-circular scale line 5 along the length direction of the sleeve, and the scale line 5 is set on the semi-open sleeve 1 opposite to the elongated notch 3 .

Abstract

The invention relates to the technical field of medical apparatuses and instruments, in particular to a spine vertebral pedicle set screw soft tissue protecting device. The protecting device comprisesa semi-opening sleeve and handheld mechanisms, the head of the semi-opening sleeve is open, a long-strip-shaped gap is formed in one side of the cylinder wall in the length direction of the sleeve, the diameter of the opening of the head end of the semi-opening sleeve is matched with the diameter of the tail of a pedicle screw, and the tail of the pedicle screw can be just sleeved with the head end of the semi-opening sleeve; the tail end of the semi-opening sleeve is closed; the handheld mechanisms are symmetrically and fixedly arranged on the two sides of the tail end of the semi-opening sleeve; according to the spine vertebral pedicle set screw soft tissue protecting device, the tail end of the semi-opening sleeve and a screw setter are cooperatively installed, spine peripheral soft tissue and a sharp medical instrument are isolated, and the phenomenon that the spine peripheral soft tissue is damaged by medical apparatuses and instruments in spine smell incision screw setting surgery is effectively avoided, so that the postoperative rehabilitation healing speed of a spine incision is ensured, and the surgical pain to a patient is relieved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a soft tissue protector for spinal pedicle screws. Background technique [0002] The pedicle is the strongest part of the spine and is the effective point of action for manipulating and immobilizing the spine. The cross-section of the pedicle is oval, surrounded by cortical bone, with a little cancellous bone in the center, and almost all cortical bone at the rear, where it is the strongest. The same point through which all forces transmitted from the back of the spine to the vertebral body pass. Pedicle instruments can maintain the normal anatomy of the spine while obtaining effective fixation, and preserve the motion segments of the spine to the greatest extent. Screwing the screw into the vertebral body through the pedicle can control the composite structure of the entire "three columns" of the spine and achieve better three-dimensional fixation. Pedicle screw place...
