A surgical instrument such as for use in vitreoretinal surgeries is described. The surgical instrument may include a pair of pincers resiliently biased toward an opened configuration and being movable toward each other into a closed configuration to engage a membrane. Each pincer may include a rounded grasping edge. The grasping edges may include a textured surface operable to induce a capillary effect between a membrane and the forceps to promote adhesion therebetween.描述一種用於例如玻璃體視網膜手術中之手術器械。該手術器械可包括向一打開組態彈性偏置且可向彼此移動而變為一閉合組態以嚙合膜之一對鉗子。各鉗子可包括一圓化抓握邊緣。該等抓握邊緣可包括可操作以在一膜與鑷子之間誘發毛細管效應進而促進彼此黏著之一紋理化表面。
