在狭窄的腭部裂隙处进行缝合操作,口鼻腔瘘道修补手术及鼻泪道吻合术中都需要缝合。由于缝合处操作范围狭小,又加上四周常有骨壁阻挡。因此,即使用很小(1/2)弧眼科缝针进行缝合时,也感到缝针转动不灵活,不易在转角处出针,还常导致缝针折断等。缝合一针十分费时,笔者为了克服这一手术操作之困难,节省手术时间,自行设计制作了一种“L”系列缝合器,只要穿一次线,就可以方便而连续不断地进行多处间断性缝合。今将“L”系列缝合器设计制作及缝合操作步骤介绍如下:(1)用9号缝纫机针,针尖截断1mm并磨尖后,在酒精灯上弯成鱼钩式进行淬火,即成需要之
In the narrow cleft palate suture operation, oral and nasal fistula repair surgery and nasolacrimal duct anastomosis need to be sutured. Due to the narrow scope of the operation of the suture, but also with the surrounding bone wall often blocked. Therefore, even with a very small (1/2) arc eye stitches for sewing, but also feel the needle rotation is not flexible, not easy at the corner of the needle, but also often lead to broken stitches and so on. Suture a needle is very time-consuming, the author in order to overcome the difficulties of this surgical operation, save the operation time, designed and produced a “L” series of stitches, just wear a line, you can easily and continuously for many intermittent Stitched. Now “L” series stitcher design and sewing operation steps are described below: (1) with 9 sewing machine needle, the tip cut off 1mm and sharpened, the alcohol lamp bent into a hook-type quenching, Serve the need
