Design and Clinical Application of Split Memory Alloy Sternum Plate / 中国医疗器械杂志

OBJECTIVE@#The design and development of split memory alloy sternum bone plate are discussed, and the effect of split memory alloy sternum bone plate internal fixation in the treatment of sternal fractures are analysed.@*METHODS@#The structure of the product is designed according to the anatomy and physiological characteristics of human bones, and the cross section shape of the product is designed according to the cross section shape of human bones. Internal fixation is effective in the treatment of sternal fracture.@*RESULTS@#The split memory alloy sternal plate was successfully designed and developed, and all the patients with sternal fractures treated by internal fixation were clinically healed, the hospitalization and fracture healing time were significantly shortened, and no obvious complications occurred.@*CONCLUSIONS@#The application of split memory alloy sternal plate internal fixation in the treatment of sternal fracture has the advantages of small trauma, simple operation, safety, reliable fixation, good histocompatibility and less complications, and is conducive to promoting fracture healing and respiratory function improvement.

The dual-source CT analysis of vascular lesions causing abdominal pain / 实用放射学杂志

Objective With the CT analysis of vascular lesions which caused abdominal pain,to improve the radiologist’s understanding of this disease,and to reduce the rate of misdiagnosis.Methods The CT data of 69 cases with vascular lesions which caused abdominal pain were analysis retrospective.Results In the vascular lesions causing abdominal pain,the occlusions of the superior mesenteric artery and vein were the most common,a total of 30 patients (43%),and the most common cause of occlusion was thrombosis (27%);There were the abdominal aorta dissection (Ⅰ+Ⅲ type+limitation)in 1 5 cases,abdominal aorta and/or iliac artery vein multiple ulcers in 9 cases (13%);Type B intramural hematoma in 6 cases (8%);Simply superior mesenteric artery dissection in 5 cases;Other less common splenic arterial thrombotic occlusion in 2 cases,pure splenic artery occlusion in 1 case and renal artery dissection in 1 case.7 cases were missed lesions,the main reason for radiologists to focus placed in the abdominal cavity prone to abdominal pain caused by solid organ or cavity organ,while ignoring the observation in the scanning range of the abdominal aorta and its main branches of the artery,lack of knowledge and experience of the lesions,and therefore not to see the consciousness or habits.Conclusion Vascular causes is an important reason causing abdominal pain.In patients with abdominal pain who underwent CT examination,if the cause of the gut and other abdominal organs can be exclused,the possibility of vascular etiology should be considered,and we should carefully observe intraabdominal artery and vein to exclude the possibility of this disease.
