A positioning patch, comprising a piece and a protective layer, the piece is selected from transparent materials, one side of the piece has a glue layer, the other side of the piece has several positioning lines, among which The material is selected from metal materials that can prevent X-ray irradiation, and the protective layer is adhered to the adhesive layer and is removably provided on one side of the sheet. The protective layer can be removed and the sheet can be attached to the human body. Several positioning lines are used to prevent X-ray irradiation, so that the irradiated X-ray sheet can establish identifiable positioning lines on the human body such as warp and weft. , The operator can easily annotate clear positioning marks on the human body, and the surgeon for the operation can accurately perform the operation at the very correct position, avoiding the wrong position, causing larger wounds or the occurrence of the wrong position. .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。
