1 材料和方法10%福尔马林固定一年左右的青壮年尸体的上肢、示教血管、神经、肌肉后的标本.方法:(1)用解剖刀或手术刀去除上肢肌肉、血管、神经.(2)把标本冲洗干净后,放入盛有5%氢氧化钾、10%过氧化氢溶液的塑料容器中浸泡2～4天.浸泡期间要随时观察标本、直到标本表面的软组织及脂肪容易清除为止.但不能损伤韧带.(3)剥离筋膜显示关节结构从胸锁关节开始,依次解剖出肩锁关节、肩关节、肘关节、前臂骨连结、手关节.胸锁关节打开关节囊,暴露关节盘.解剖肩关节时,肩关节囊薄而松驰,唯其下部最薄弱,稍不留心就会戳伤关节囊,故要用锋利的刀片顺纤维束修净筋膜.如刀片不锋利容易将纤维束和筋膜一起带起.肘关节打开关节囊,充分暴露肱尺关节、肱桡关节、桡尺近侧关节,显示出桡骨环状韧带、桡测副韧带、尺侧副韧带.前臂骨间膜是坚韧的纤维膜、薄如纸.制作时要十分细心,用手术刀轻轻把它和筋膜、脂肪分离开来.(4)用解剖刀修洁骨上的软组织,但不能损伤骨质.(5)将制作好的上肢骨连结标本用清水冲洗后用10%过氧化氢溶液漂白一周左右以增强标本光泽度.(6)将标本凉干涂刷鸡蛋清按解剖学姿势摆正封装于盛有5%福尔马林溶液的有机玻璃盆内保存.
1 Materials and Methods 10% formalin fixed a year or so of young adult body upper extremity, showing blood vessels, nerves, muscle specimens after.Methods: (1) with a scalpel or scalpel to remove the upper limb muscles, blood vessels, nerves (2) After the specimen is rinsed, put into a plastic container containing 5% potassium hydroxide and 10% hydrogen peroxide for 2 to 4 days, observe the specimen at any time during the immersion until the soft tissue and fat on the specimen surface Easy to remove, but can not damage the ligament. (3) peel fascia shows the structure of the joint starting from the sternoclavicular joint, in turn anatomical acromioclavicular joint, shoulder joint, elbow joint, forearm bone joint, hand joints. , Exposing the disc .Discussion Shoulder joint, shoulder joint capsule thin and loose, only the lower part of the weakest, a little careless will pound the joint capsule, it should use a sharp blade along the fiber bundle to repair the net fascia .Such as the blade Not easy to bring the fiber bundles and fascia together.Open joint capsule to open, fully exposed ulnar joint, brachial and radial joint, proximal radioulnar joint, showing radial ring ligament, radial collateral ligament, ulnar side Ligament. Forearm interosseous membrane is a tough fibrous membrane, Such as paper. Production be very careful, gently with a scalpel and fascia, fat separated. (4) with a scalpel to repair the soft tissue on the bone, but can not damage the bone. (5) will be made good Of the upper extremity bone specimens with water rinse with 10% hydrogen peroxide solution bleach for about a week to enhance the specimen gloss. (6) The specimen is dry brushing egg white placed in an anatomical position is packaged in Sheng 5% Marlin solution stored in a plexiglass basin.
