目的 :研制更加适合诊治咽腔、口腔疾患的开口器及固定支架。方法 :冷光源开口器由臂、体、压舌板、冷光源及配套固定支架构成 ,压舌板末端形成“U”形 ,两臂宽度恰好容纳麻醉导管 ,在“U”形压舌板两臂背面中部凿出直径 3mm的纵行沟槽 ,冷光源导光纤维插入其内 ,配制两臂插在手术床两侧滑道上的螺母 ,可前、后、上、下移动 ,上方附有器械托盘的固定支架。应用传统的Davis开口器和冷光源开口器各行手术 30例 ,对比术中出血、开口器脱出、手术时间及术后并发症的发生率。结果 :冷光源开口器将光线直接导入术区 ,光照充足 ,术野清晰 ,麻醉导管固定在舌与压舌板之间 ,既移开了障碍物 ,又保持了通畅。固定支架固定牢靠 ,器械托盘方便手术。两组病例各项指标经统计学处理差异有显著性 (P <0 .0 5 ) ,说明冷光源开口器明显优于传统Davis开口器。结论 :冷光源开口器及其固定支架可免戴头灯 ,合理固定麻醉导管 ,配套支架的应用缩短了手术时间 ,减少了并发症的发生 ,并避免了预置性气管切开术 ,是一种理想的开口器
Objective: To develop more suitable for the treatment of pharyngeal cavity, oral disease opening device and fixed stent. Methods: Cold light source opening device consists of arm, body, tongue spatula, cold light source and supporting fixed bracket, the end of the tongue depressor to form a “U” shape, arms width just to accommodate the anesthesia catheter, in the “U” The middle of the back of the arm is cut into a longitudinal groove with a diameter of 3mm and a cold light guide fiber is inserted into the middle of the arm to prepare a nut with two arms inserted on the slide rails on both sides of the operation table. Pallet mounting bracket. The traditional Davis opener and cold light source opener were operated on in 30 cases. The operative bleeding, opener ejection, operation time and the incidence of postoperative complications were compared. Results: The cold light source opener direct the light into the operation area, sufficient illumination and clear surgical field. The anesthesia catheter was fixed between the tongue and the tongue depressor, which not only removed the obstacle but also kept the patency. Fixed stent fixed, instrument tray for surgery. There was significant difference between the two groups (P <0.05), indicating that the cold light source opener is obviously superior to the traditional Davis opener. Conclusion: The cold light source opening device and its fixing bracket can be avoided wearing a headlamp, reasonably fixing the anesthesia catheter, and the application of the supporting bracket can shorten the operation time, reduce the occurrence of complications and avoid the preset tracheotomy, which is one Kind of ideal opener
