后咬式上颌窦打孔钳 7英寸 工作长度100mm 成人直型 2.5mm x 7.0mm 咬合面 5.0mm宽头 环柄

鼻窦与上颌窦手术的精准入路

navigating the confined anatomy of the maxillary sinus requires instruments that combine precise reach with reliable tissue control. This backbiting ostrum antrum punch forceps is engineered to facilitate effective access during adult ENT and general surgical procedures. With a straight design and a 100mm working length, it offers direct visualization and maneuverability within the antral cavity. The 5.0mm wide head accommodates the specific 2.5mm x 7.0mm bite geometry, allowing for controlled removal of bone or tissue fragments. Ring handles provide familiar ergonomics for steady manipulation, supporting surgeons in maintaining accuracy while working in tight spaces where standard forward-biting instruments may lack the necessary angle or leverage.
