Provided is a surgical operation appliance with pressure sensing and vision feedback functions, which comprises a surgical operation appliance body and a piezo-chromic element. The surgical operation appliance body is provided with a work piece. The work piece is provided with a visible surface. The piezo-chromic element is mounted on the visible surface of the work piece of the surgical operation appliance body for generating a color change when sensing a pressure. As a result, when using the surgical operation appliance of the present invention to proceed with a surgical operation, the doctor can directly observe the piezo-chromic element. When the piezo-chromic element collides with other surgical operation appliances or presses internal organs or tissues within the non-affected body of a patient, the piezo-chromic element senses the pressure and thus immediately generates a color change for direct and visual judgment by the executive doctor.一種具壓力感測及視覺回饋功能的手術器具,其包含有一手術器具本體與一壓致變色元件,該手術器具本體具有一工作件,該工作件具有一可視表面,該壓致變色元件設置於該手術器具本體之工作件的可視表面,係於感測到壓力時產生顏色的變化;藉此,醫師操作本創作手術器具進行手術時,可直接看到該壓致變色元件,當該壓致變色元件碰撞其他手術器具或壓到患者非患部體內的器官或組織,該壓致變色元件感測到壓力以立刻產生顏色變化,供執刀醫師直觀判斷。10‧‧‧手術器具本體11‧‧‧柄部12‧‧‧工作件121‧‧‧可視表面122‧‧‧夾取面20‧‧‧壓致變色元件
