New description: 【New technical field of the invention】 This creation department provides the field of “can be poured into the bone mud”, and the technology provides a multi-axial Wei towel seal, which can be quantitative and effective. In the vertebral body of the loose vertebral body, the angle deviation caused by the misplacement of the distraction ribs and the correction of the implant eccentricity increases the interface strength of the bone nail and the spine to achieve the purpose of strengthening stability. Prior art] For patients with osteoporosis, the stable and effective fixation of the spinal nail is an important part of the success or failure of the spine surgery. The method used is to infuse the bone mud in the microscopy (4) bone nail implantation channel. After that, the nail is locked again to improve the interfacial strength between the nail and the bone. 'The traditional bone nail is one-way and cannot adjust the restriction of the nail locking direction' or the bone mud perfusion is insufficient, and the bone mud distribution Inhomogeneity, etc., the bone nail, bone mud and spinal vertebral body can not be well combined in the __, resulting in the bone nail can not be stable and effective fixation. [New content] A multi-axial bone mud perfusion hollow bone screw, It includes: a bone screw body, a multi-axial rotation threading head and a stop screw, the bone screw body is provided with an axial central through hole and a plurality of radial perforations, the plurality of radial perforations and the axial center through hole are one side After the multi-axial bone mud perfusion hollow bone screw is implanted into the vertebral body, the axial center through hole can be combined with the bone mud extrusion auxiliary device to squeeze the bone mud through the axial center through hole channel and inject into the bone mud. The free end of the bone screw body is provided with a ball portion. A multi-axial rotating thread head has a ball recess for the multi-axial rotation of the ball portion therein. The multi-axial rotating thread head is set to a hollow U-shaped Zhao. The hollow u-shape is intended to have a thread therein, and a fixing rod has to pass through the U-shaped body of the multi-axially rotating threaded head, and a stop screw can be inserted into the U-shaped body of the multi-axially rotating threaded head and abutted against the thread. Fixing the fixing rod, the multi-axial bone-soil perfusion hollow bone screw can adjust the locking direction of the patient's bone condition, thereby improving the success rate of the operation. [Embodiment] The following specific embodiments are only the best embodiment of the present invention. Illustrative, unintentional The scope of the creation. Those who have the ordinary knowledge in the field can make appropriate changes and corrections within the scope of the spirit of the creation by the disclosure of the creation. Referring to the first to third figures, the creation provides A multi-axial bone-soil perfusion hollow bone screw' includes: a bone screw body 11, a multi-axial rotation threaded head 12 and a stop screw 13 'the bone screw body 11 is provided with an axial center through hole 21 and a number The radial through holes 22 ′ are electrically connected to the axial center through hole 21 , and the free end of the bone nail body 11 has a spherical portion 14 and a concave tool locking hole 15 . After the hollow bone screw is implanted into the spine vertebral body, the cypress to the center through hole 21 can be combined with the bone mud extrusion auxiliary device to squeeze the bone mud through the axial center through hole 21 channel and inject into the bone mud. The mud oozes out through the axial center through hole 21 and the radial perforation 22 to solidify in the vertebrae of the vertebrae. The free end of the bone screw body 11 is provided with a ball portion 14 having a ball recess 121 for multi-axial rotation of the ball portion 14 therein. The multi-axial rotation thread head 12 " Further, a hollow U-shaped body 122' is provided with a thread 123 in the hollow U-shaped jaw 122. A fixing rod 31 passes through the U-shaped body 122 of the multi-axially rotating threaded head 12, and a stop screw 13 can be inserted into the shaft. The thread 123 in the IJ-shaped body 122 of the threaded head 12 is axially rotated and the fixing rod 31 is fixedly fixed. The multi-axial bone-infused hollow bone screw can adjust the locking direction of the patient's bone condition, thereby improving the chance of successful operation.
