屏東一名31歲楊姓男子，因耕種香蕉的農務需要，長年搬重物導致去年開始左腰臀痛到腳踝，嚴重時甚至痛到生活無法自理只能躺平，經就醫檢查後顯示為「第五腰椎及第一薦椎神經壓迫」，前往高雄就醫進行微創手術治療後回復日常生活，醫師表示，若長年動作不當容易引發神經壓迫，盡快治療能提升生活品質。

楊男因腰痛到生活無法自理，經核磁共振檢查顯示為「第五腰椎及第一薦椎神經壓迫」，前往高雄七賢為脊椎專科醫院就醫，經無鋼釘穩定器微創手術治療後，術後3天就無需使用助行器行走，經復健後已恢復日常生活，現在工作都堅持穿戴護腰避免復發。

七賢醫院副院長朱晟瑋說明，臨床上常見腰椎或薦椎神經受到壓迫通常是患者長年日常不當動作所造成，案例中的楊先生是坐輪椅進入診間且痛到身體傾斜向右邊，已嚴重影響生活品質故建議手術治療。

楊男接受本院推行多年的無鋼釘穩定器微創手術，已成功幫助許多深受退化性或外傷性脊椎疾病的患者解除病痛並且回復正常生活。該手術不僅安全性高，患者術後恢復快速，長期而言對生活品質改善也優於傳統的脊椎融合鋼釘固定手術，建議有相似症狀民眾盡快就醫接受治療。

The horn antenna has a distinctive design that is enlarged towards the end. Horn antennas typically feature a directional radiation pattern with a high antenna gain of 10-20 dBi, some antennas have a higher gain such as the standard horn antenna up to 25 dBi. Horn antennas feature a low VSWR and a wide impedance bandwidth.

Double Ridged Horn Antennas are very popular from 200 MHz frequency to higher frequencies up to 40GHz. We have recently extended the usage frequency of this antenna up to 60 GHz.

This antenna's operating frequency has recently been increased to 60 GHz. The research process for the product line is still ongoing but is planned to be completed this year. To receive the most recent price and technical information on the new product, please contact us for more information.
