Problems solved by technology

This traditional operation mainly relies on manual work, which is closely related to the doctor's mental state and proficiency, and the accuracy is poor; moreover, during the fluoroscopy process, the doctor needs to maintain the fracture reduction position all the time, and the doctor is exposed to radiation for a long time, so the safety is not good. to effective protection

Abstract

The invention discloses a pelvis fracture reduction device. The reduction device comprises a first outer fixing frame and a second outer fixing frame which are connected through at least one connecting rod. At least two of a supraacetabular transverse screw, an LC-2 screw and a gluteus medius column screw are fixed to the first outer fixing frame. The supraacetabular transverse screw, the LC-2 screw and the gluteus medius column screw are used for fixing the pelvis on the uninjured side. At least one shanz screw is fixed to the second outer fixing frame, connected with the pelvis on the affected side and used for pulling and turning over and / or pushing the pelvis on the affected side. Correspondingly, the invention further discloses a using method of the pelvis fracture reduction device. The pelvis fracture reduction device is simple in structure, good in reduction effect, small in injuries to a patient, and capable of remarkably shortening the time when a doctor and a patient are exposed under rays.

Description

technical field [0001] The invention belongs to the field of medical equipment, and in particular relates to a pelvic fracture reduction device and its application method. Background technique [0002] For vertically unstable pelvic ring injuries, special emphasis should be placed on early supracondylar traction of the affected femur, reduction of the posterior pelvic ring displacement through the sacroiliac joint or the posterior part of the iliac crest, or dislocation of the sacrum, and efforts should be made within 24 hours to 72 hours after injury. The reset operation should be carried out within hours, otherwise the best reset opportunity will be lost. [0003] Therefore, for the reduction of pelvic fractures, it is necessary to perform high-dose traction as soon as possible. Under normal circumstances, the traction weight is 7% to 8% of the patient's body weight, and the dose of traction needs to be maintained for 12 hours; then the pelvic exit and entrance positions ...
