目的 探讨深部软组织内金属异物透视下套管法钳取术的可行性和安全性。方法 2 3例 6 9颗金属异物深部软组织内存留患者。异物长度为 0 .2～ 3.0cm ,宽度为 0 .1～ 0 .5cm ,离体表最短距离为 2～ 5cm ,存留时间 7～ 12 0d。采用钳夹式椎间盘摘除器套装 ,透视下用定位针将外套管引入到异物处 ,并送入髓核钳夹住异物取出体外。结果 2 3例患者 6 9颗异物均 1次成功取出。手术时间为 8～ 15min ,X线曝射时间为 1～ 4min。未发现并发症。结论 透视下套管法钳取术 ,是取出深部软组织内金属异物的 1种新的简便、安全可行的方法。
Objective To investigate the feasibility and safety of cannulated method of plierstomy under deep fluoroscopic metallic foreign bodies. Twenty-three cases of 69 cases of metal foreign body deep soft tissue in patients with memory retention. Foreign body length of 0.2 ~ 3.0cm, width of 0 .1 ~ 0 .5cm, the shortest distance from the body surface is 2 ~ 5cm, retention time 7 ~ 120d. The use of jaw-type disc extender set, with a positioning needle under fluoroscopy to the foreign body at the introduction of foreign bodies, and sent to the nucleus forceps clamp the foreign body removed. Results Twenty-nine patients with 23 foreign bodies were successfully removed one time. The operation time is 8 ~ 15min, X-ray exposure time is 1 ~ 4min. No complications found. Conclusion Under the perspective of cannulated forceps retrieval, a new simple, safe and feasible method for removal of metallic foreign bodies in deep soft tissues.
