【摘要】：艦船沖擊傷作為水面艦船受水下非接觸爆炸瞬間強(qiáng)烈沖擊運動經(jīng)船體和甲板傳遞作用于艦船上人員從而導(dǎo)致的不同程度的損傷,它甚至危及艦員生命,嚴(yán)重影響艦船戰(zhàn)斗力。自80年代以來,國內(nèi)外研究機(jī)構(gòu)都對其給予了高度重視,進(jìn)行了大量的研究,但這種艦船瞬間劇烈沖擊運動對人員視覺系統(tǒng)產(chǎn)生何種效應(yīng)即艦船眼部沖擊傷的研究鮮有報道。視覺器官是人體最重要的感覺器官,視功能對戰(zhàn)斗力的影響至關(guān)重要,艦船眼部沖擊傷的研究對于保持和提高艦船人員戰(zhàn)斗力具有重要意義,本研究旨在通過艦船沖擊模擬裝置進(jìn)行動物實驗研究分析艦船眼部沖擊傷的傷情特點和致傷機(jī)制,為以后做救治研究制定防護(hù)措施奠定基礎(chǔ)。 本研究首先在現(xiàn)有的艦船沖擊傷動物模型基礎(chǔ)上,創(chuàng)建出更接近實船效果,經(jīng)濟(jì)簡便,易搬運攜帶的艦船沖擊傷模擬裝置;動物模型建立后,選擇60g、80g、100g三個沖擊加速度檔次,分三組進(jìn)行動物實驗,每組隨機(jī)5只青紫蘭兔分別于傷前、傷后1h、1d、3d、7d、2w連續(xù)觀察其眼部臨床特點、測試其視覺電生理變化并進(jìn)行眼底照相及熒光造影,然后第一組中另有6只分別在這六個時間點經(jīng)頸動脈灌注硝酸鑭,然后取眼球組織觀察光電鏡改變。第二組

[Abstract]:Ship impact injury, as a kind of damage caused by the strong impact motion of the surface ship transmitted through the hull and deck, even endangers the life of the ship and seriously affects the combat effectiveness of the ship. Since 1980s, research institutions at home and abroad have attached great importance to it and carried out a lot of research, but there are few reports on the effect of instantaneous severe impact movement on the visual system of people, that is, the impact injury of the eye of the ship. Visual organ is the most important sensory organ of human body, and the influence of visual function on combat effectiveness is very important. The research of ship eye impact injury is of great significance to maintain and improve the combat effectiveness of ship personnel. The purpose of this study is to analyze the injury characteristics and injury mechanism of ship eye impact injury through animal experiment through ship impact simulation device, and to lay a foundation for future treatment and research to formulate protective measures. In this study, on the basis of the existing animal model of ship impact injury, a simulation device of ship impact injury is established, which is closer to the actual ship effect, economical and simple, and easy to carry. After the animal model was established, three shock acceleration grades of 60g, 80g and 100g were selected and divided into three groups. Five rabbits in each group were randomly divided into three groups. Five rabbits in each group were randomly divided into three groups before injury, 1 day, 3 days, 7 days, 2 weeks after injury, and their visual electrophysiological changes were measured and fundus photography and fluorescein angiography were performed. Then, 6 rabbits in the first group were perfused with lanthanum nitrate through carotid artery at these six time points. Then the eyeball tissue was taken to observe the changes of light electron microscope. Group II
