隨著人口老化,膝關節的退化而產生不適症日趨增多,尤其是骨科退化性關節的病患亦跟著日益成長,臨床上最常見的有因膝關節髕骨的滑車溝角產生的病變,而溝角的大小代表股骨髁間溝的深淺以及滑車的發育情況,因此思考設計專為膝關節攝影專用的膝關節攝影輔助架,增加病患接受攝影時的舒適度與方便性,進而提升影像品質降低病人曝露劑量是一個刻不容還問題。 本研究針對製作膝關節攝影所製成的輔助架,由22個小工件來組成,金屬切割完後再陽極處理,取其為黑色,並在底座加裝儀器輪以增加放射師移動便利性,有別於其他設計之攝影輔助架,本輔助架採用鋁合金材質,採多段式調整功能,以方便不同角度彎曲的病人,設計成可隨檢查台高低調整高度的基座,片匣定位桿亦可調整長度,其長度為22~37.5公分及隱藏式提把,並且片匣定位桿與小腿置放架可摺收不佔空間,提供具可收納的特色。 因應臨床越來越大的攝影需求,提供一個便利、易於收藏及可改變角度的膝關節輔助架,其可使用之角度為30°,35°,40°,45°以及50°,以利於膝關節受損不易彎曲之病人使用,進而增加臨床上攝影之方便性及造福於膝關節不適症之病患。
The sulcus angle of the femoral trochlea is particularly important for evaluating the patellofemoral joint(PFJ). The location and configuration of the intercondylar groove of the distal femur is clinically significant in the mechanics and pathomechanics of the PFJ. The aged society brings elder people in the tendency of increment of this disease. The imaging of PFJ has been becoming more important in the radiology department for the sulcus angle. The auxiliary frame adopts aluminum alloy and adopts multi-stage adjustment function to facilitate the bending of patients with different angles. The design of the base and hidden height can be adjusted according with the height of the examination table. The handles are easy to accommodate and designated fashionally. Composed of small parts, a total of 22 parts were cut. After metal cutting, the parts were anodized and black, and the instrument wheel was added to the base to allow the user to move easily. The positioning bar can also be adjusted in length. The length of the positioning bar is 22~37.5 cm and the hidden handle. The cassette positioning bar and the calf placing frame can be folded without occupying space, and can provide accommodating features. The knee bending angle was designed with five angles. In order to meet the increasing demand for photography in the clinic, a convenient, easy-to-store and angle-changing knee assist frame that can be used at angles of 30°, 35°, 40°, 45°, and 50° in order to meet the increasing demand for clinical photography. The use of patients with impaired joints that are difficult to bend will increase the convenience of clinical photography and benefit patients with knee discomfort.
