[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Reference Figure 1-3A disposable sterile universal plum wrench comprises: a handle 6, a connecting rod 5 fixed to the handle 6, a connecting block 2 fixed to the connecting rod 5, and a wrench head 1 movably connected to the connecting block 2; a positioning assembly for positioning the wrench head 1, the positioning assembly comprising a positioning handle 7 and a sleeve 8 fixed to the positioning handle 7. When in use. Put the wrench head 1 into the sleeve 8, adjust the sleeve 8 through the positioning handle 7 to drive the wrench head 1, find a suitable angle, insert the wrench head 1 into the tail of the screw to be implanted, and then hold the handle 6 and rotate it clockwise to gradually implant the screw into the required surgical site of the vertebral body. The wrench head 1 is movably connected to the connecting rod 5, and then when the handle 6 is turned, the position of the handle 6 can be adjusted to facilitate rotation.

[0021] Furthermore, a connecting groove is provided at one end of the connecting rod 5 away from the handle 6, and a connecting block 2 is placed in the connecting groove. The connecting block 2 includes a screw fixing portion and an axial connecting portion fixed to the screw fixing portion, wherein the screw fixing portion is movably connected to the connecting groove through a connecting screw 3. The screw fixing portion and the axial connecting portion are arranged perpendicular to each other, and the axial connecting portion and the connecting rod 5 are arranged perpendicular to each other, and the wrench head 1 is movably connected to the axial connecting portion. The wrench head 1 is movably connected to the axial connecting portion through a rotating shaft, and the wrench head 1 rotates around the rotating shaft; the connecting rod 5 rotates around the connecting screw 3. When in use, the doctor can select the most suitable operating angle of the wrench head 1 or the handle 6 according to the specific surgical needs and the specific conditions of the patient. This flexible design greatly increases the convenience of surgical operation and makes the instrument particularly suitable for minimally invasive surgical operations. By reducing the complexity of surgical operations, the instrument helps to shorten the operation time and reduce the patient's postoperative recovery burden.

[0022] Further, the end of the wrench head 1 away from the connecting block 2 is a plum blossom wrench. The end of the wrench head 1 is a plum blossom wrench, which can be used in conjunction with the plum blossom-shaped implant screw tail.

[0023] The device of the present application is packaged in a sterile manner before use, which not only effectively saves the time for preoperative preparation, but also significantly reduces the risk of cross infection during surgery. The use of sterile packaging ensures that the device is completely sterile from the time the package is opened to the time it is used, providing patients with a higher level of surgical safety. Moreover, the device is a disposable device.

[0024] Workflow: When in use, put the wrench head 1 into the matching positioning tool sleeve. The operator correctly places the wrench head 1 inside the matching positioning tool sleeve. This step is to ensure the accurate docking of the wrench head 1 and the sleeve 8.

[0025] Adjust the wrench head 1 to a suitable operating angle. Through the flexible adjustment mechanism of the positioning tool sleeve, the operator can accurately adjust the angle of the wrench head 1 according to the surgical requirements and the patient's specific conditions to achieve the best implantation path and position.

[0026] Insert the tail of the screw. After adjusting the angle, the operator inserts the wrench head into the tail of the screw to be implanted, preparing to start the screw implantation process.

[0027] Rotation operation: The operator holds the handle 6 tightly and rotates it clockwise, and the screw is slowly and steadily implanted into the predetermined surgical site of the vertebral body by gradually increasing the rotational force.
