When a spine orthopedic surgeon needs to implant a side block screw in a cervical vertebra operation, the side block screw can be placed on the screw hole 3 on the adjusting piece 2, the side block screw is balanced with the main body 1, then the cervical vertebra side block screw positioner is directly placed at the screw placing position of the cervical vertebra, the main body 1 is fixed on the cervical vertebra, and then the implantation direction of the side block screw is adjusted through the adjusting piece 2, so that the side block screw is safely and quickly implanted, and the surgeon and a patient are prevented from being irradiated by X-rays for many times; the cervical vertebra side block screw positioner can realize balanced screw placement and can achieve an accurate implantation effect.

Specifically, as shown in fig. 1-2, the main body 1 includes an insertion portion 4 and an outer side portion 5, and the angle between the adjusting member 2 and the outer side portion 5 is an acute angle. In the present embodiment, the main body 1 is a strip-shaped sheet.

When the cervical vertebra side block screw positioner is arranged at the screw placing position of the cervical vertebra, the inserting part 4 of the main body 1 is inserted into the screw placing position of the cervical vertebra, at the moment, the included angle between the adjusting piece 2 and the inserting part 4 is preferably an obtuse angle, namely, the included angle between the adjusting piece 2 and the outer side part 5 is an acute angle, so that the adjusting piece 2 is prevented from colliding and rubbing with the cervical vertebra when the angle is adjusted, and other processes of spinal orthopedic surgery are prevented from being influenced.

Preferably, a degree disk 6 is arranged on the main body 1.

The degree disc 6 can obviously display the degree of rotation of the adjusting piece 2, so that the angle of the side block screw on the screw hole 3 of the adjusting piece 2 can be known, and the process of adjusting and implanting the side block screw is clearer; the operation physician can adjust the implantation direction of the lateral mass screw according to the angle, the operation is usually completed by several operation physicians together, the treating physician can directly tell the physician who performs the implantation of the lateral mass screw to adjust the degree, the performing physician can quickly and accurately complete the implantation of the lateral mass screw according to the degree disc 6, the treating physician does not need to teach one by one again, the operation time is saved, and the operation is more beneficial to the body of a patient.

Preferably, the dial gauge 6 is located at the corner of the adjusting member 2 from the outer side 5. More preferably, the dial of degrees 6 may be sector shaped.

When the cervical vertebra side block screw positioner is used, the adjusting part 2 is usually used for adjusting the included angle between the adjusting part 2 and the outer side part 5, and the degree disc 6 is directly arranged at the included angle between the adjusting part 2 and the outer side part 5, so that the viewing by an operator is facilitated, and the operation process is smoother.

In the present embodiment, the dial 6 is directly imprinted on the main body 1, which not only can realize the function thereof, but also can save the production cost.

Preferably, the screw holes 3 are elongated holes. More preferably, the screw hole 3 is arranged along a length direction of the adjusting piece 2.

Screw hole 3 sets up long banding, and the side piece screw can move on it, when the implantation direction of having adjusted the side piece screw through adjusting part 2 but when not very accurate yet, can also finely tune through the removal of side piece screw on screw hole 3, makes it implant the direction more accurate, improves the implantation quality of side piece screw.

Preferably, a screw sleeve 31 is arranged at the screw hole 3, and the screw sleeve 31 can move on the screw hole 3. More preferably, the screw housing 31 is perpendicular to the screw hole 3, and a cross-sectional area of an end of the screw housing 31 is larger than an area of the screw hole 3.
