Abstract

The invention discloses a positioning device for skull drilling. The positioning device comprises a main mounting frame, front fixing rods and a rear fixing rod. During use, the main mounting frame isarranged above the head of a patient, and extends in the left-right direction of the patient; the main mounting frame is fixed to the head of the patient; the front fixing rods are movably connectedwith the main mounting frame; one end of each front fixing rod extends to the rear of the main mounting frame, and is used for positioning a drilling point, and the other end of each front fixing rodextends to the front of the head of the patient, is suspended in front of the head of the patient, and is used for being fixed to the head of the patient; one end of the rear fixing rod is movably connected with the main mounting frame, and the other end of the rear fixing rod extends to the rear of the head of the patient and is used for supporting the head of the patient from the rear portion; adrill bit fixing rod is movably connected onto the main mounting frame, and a drill bit can be effectively positioned by adjusting the position of the drill bit fixing rod; and the drill bit is arranged in the drill bit fixing rod, and drills the drilling position located by the front fixing rods, so that the accuracy of the drilling position can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of surgical equipment, in particular to a skull drilling positioning device. Background technique [0002] Patients with severe cervical fracture and dislocation are often accompanied by spinal cord injury, and most of them are accompanied by multiple injuries. If not treated in time, severe cases may cause spinal cord injury, edema spread and even life-threatening. Therefore, clinicians need to give reasonable internal fixation in time to reconstruct the stability and reduce spinal cord injury. [0003] Preoperative cranial distraction has a long history of clinical application. This operation is simple and practical, and plays an important role in maintaining the stability of the fracture and maximizing the reduction of the cervical sequence. Preoperative cranial traction can restore the normal sequence of the fractured and dislocated cervical vertebrae, avoid secondary damage to the spinal cord, and al...
