Halo-pelvic ring traction device

Abstract

The invention discloses a halo-pelvic ring traction device. The halo-pelvic ring traction device is characterized by comprising a head bracket, a pelvic bracket, and support rods connected between the head bracket and the pelvic bracket, wherein the head bracket comprises a ring article, a harnpan fixing needle transversely arranged along a ring of the ring article, and a connector connected to two ends of the annular article, wherein the pelvic bracket comprises a hoop article and two pelvic bone needles fixed on the hoop; the two pelvic bone needles are arranged at an acute angle, and more than three support rods are provided and arranged along the hoop of the hoop article. Compared with the prior art, the halo-pelvic ring traction device has the advantages that cervical fracture and dislocation and severe spinal deformity can be treated under the condition that a sufferer does not need to lie in bed.

Description

technical field [0001] The invention relates to a medical device. Background technique [0002] When the curvature of the spine develops to a certain degree, it will be difficult for any simple instrument surgery to play a role. Forcible surgical correction will cause excessive tension in the spinal cord, which may lead to paraplegia. After the spine is straightened, internal support and internal fixation can be performed. The designed children's cephalopelvic ring traction method for treating severe spinal curvature is to gradually straighten the curved spine during the slow retraction process, and then perform internal support and internal fixation easily. This method can turn major operations into minor operations , greatly simplifying the operation process and increasing the safety of the operation. After the head-pelvic ring traction, the second surgical correction is performed. The surgical trauma is small and the course of treatment is short. It can significantly im...

Problems solved by technology

In addition, the existing method for treating cervical fracture and dislocation is that the patient lies on the bed, and the skull is pulled by a traction device arranged on the head of the bed, and then the fracture and dislocation of the cervical spine is pulled. This method requires the patient to lie on the hospital bed for a long time , and it is difficult to turn over, bedsores are prone to occur, and there is pain in the headrest, which is unbearable for the patient during long-term treatment, and for severe cervical dislocation, due to traction, it is completely dependent on the friction force of the person lying on the bed and the traction device. traction, the traction force should not be very large, so the therapeutic effect of this traction reduction method is not obvious
