A positioning patch comprises a body and a protective layer. The body is selected from transparent materials. One side of the body has an adhesive layer. The other side of the body has a plurality of positioning lines. The material is selected from a metal material that can prevent X-ray irradiation, the protective layer is adhered to the adhesive layer, and is removably disposed on one side of the sheet body.保护 The protective layer can be removed and the sheet can be adhered to the human body, and the X-rays can be prevented by several positioning lines, so that the irradiated X-ray film can establish positioning lines such as warp and weft on the human body. The operator can easily note the clear positioning marks on the human body, and the surgeon for the operation can accurately cut the knife in a very correct position, avoiding the wrong position, causing the patient's larger wound or the wrong position to occur. .一種定位貼片，包含一片體、一保護層，該片體選自透明材料，該片體一側具有一膠層，該片體另一側表面具有數條定位線，該數條定位線之材料選自可阻止X光照射之金屬材料，該保護層黏貼於該膠層，且可移除狀設於該片體一側。俾可將保護層移除而將片體黏貼於人體上，藉由數條定位線阻止X光照射，使照射後之X光片於人體上建立起可識別位置之定位線條如經線、緯線，操作人員可以很方便在人體上註記清楚的定位標記，供開刀手術的外科醫生，能夠精準的在非常正確的位置下刀，避免產生錯誤位置，造成病人更大的傷口或下錯位置的發生。
