Background
Currently, medical surgical robots are developing very rapidly. In orthopedics, surgical robots represented by "breguet" are gradually accepted by more and more clinicians due to the advantages of precision, rapidness, reduction of radiation damage, reduction of learning curves and the like.
However, when an orthopedic surgery robot is clinically used for spinal surgery, the optical positioning receiver navigated by the robot must keep no relative displacement with the spinal column in the whole surgery, otherwise, the navigation accuracy cannot be guaranteed. Therefore, the conventional optical positioning receiver needs to enlarge an incision to the head end to expose the spinous process of the upper spine and fix the spinous process stably by using a clamp during the spine surgery, but the incision is enlarged as a result of the operation, and certain additional injury and pain are caused to the patient. Moreover, if robot navigation is needed in minimally invasive spine surgery, an additional incision is needed to fix the optical positioning robot, which obviously goes against the original purpose of minimally invasive surgery.

Preferably, the mounting is fixing screw, be equipped with on the base with fixing screw assorted screw hole, fixing screw tightly touches or keeps away from the lateral part of movable rod through the screw hole.
Preferably, the outer end of the fixing screw rod is provided with a rotating button.
Preferably, the bevel guide bar is rotatably connected with the movable bar through a connecting rod.
Preferably, the movable rod is provided with a through hole, the connecting rod is provided with a rotating rod, and the rotating rod is rotatably connected with the through hole.
Preferably, the end of the rotating rod is provided with a rotating button.
Preferably, the movable rod is provided with scale marks.
Compared with the prior art, the invention has the beneficial effects that: when the invention is applied to spinal surgery, the optical positioning receiver can be firmly fixed on the spinous process without being used as an incision, thereby ensuring that the optical positioning receiver does not displace with the spinal column in the whole surgery and ensuring the surgery accuracy of robot navigation.
