Individualized guiding template assisting in setting pedicle screw into small incision and manufacturing method of individualized guiding template

Abstract

The invention discloses an individualized guiding template assisting in setting a pedicle screw into a small incision. The individualized guiding plate comprises at least one group of pedicle screw setting components, each pedicle screw setting component comprises two bottom plates arranged on two sides of a spindle section to be set with a screw symmetrically and two screw feed catheters fixed on the bottom plates respectively, the structures of the bottom plates are matched with the spindle anatomical structure around a point to set the screw, the screw feed catheters are determined by screw setting channels through reasonable calculation and connected on the bottom plates. The bottom plates are connected with the screw feed catheters determined by the screw setting channels through reasonable calculation, accuracy in screw setting and safety in operation can be guaranteed without X-ray examination, and ray exposure of medical staff and patients is reduced.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to the field of pedicle screw placement. Background technique [0002] Pedicle screw technology is widely used in spinal trauma, degeneration, tumor and other diseases, and can achieve good fixation effect. At present, the commonly used pedicle screw technology mainly includes manual screw placement, C-arm machine fluoroscopy screw placement, CT navigation-assisted screw placement, etc. These screw placement methods have disadvantages such as poor safety, more fluoroscopy, and high price. In recent years, the small-incision pedicle screw technique has become more and more popular among doctors and patients because of its advantages of less trauma, less bleeding, and faster recovery. However, it puts forward higher technical requirements for the operator. To ensure the safe and accurate completion of small incision surgery, the surgical process must be completed under C-arm machin...
