Definitions
- the present invention relates to an injectable composition for labeling lesions and a method for providing information on the location of a lesion using the injectable composition.
- a technique for minimizing the surgical range during surgery is essential for the health and welfare of the patient after the surgery.
- small breast breast surgery for resection of surgery is required in fewer countries than in other countries to achieve the goal of breast conservative treatment.
- the surgical range is determined by the lesion and the marginal margin around the lesion. If the gynecologist does not know the exact location and extent of the lesion, the marginal margin around the lesion is large. This is because the tumor may remain on the resection surface while reducing the surgical range.
- the location of the patient's micro lesions is confirmed by ultrasound, mammography, or magnetic resonance imaging before the operation, the location of the identified lesion is marked, and the tissue of the marked area is removed.
- a method of drawing on the surface of the skin, using a wire, or injecting a black pigment such as charcoal is used.
- the method of drawing with a pen on the skin to indicate the location of the lesion is that the shape of the breast changes a lot in the diagnosis and in the operating room due to the characteristics of the very flexible breast tissue. It can be used most easily due to insufficient marking on the skin surface, but has the disadvantage of low accuracy.
- the method of stabbing breast lesions using wires requires the wires to be inserted vertically into the skin surface, but must be inserted diagonally in order to affect the ultrasonic probe. Due to the fact that it can move according to the lower accuracy than expected, the inserted wire interferes with the surgery, there is a disadvantage that the procedure for further cutting the insertion portion of the wire must be performed.
- the method of injecting a pigment, such as charcoal has the advantage that the injected pigment binds to the lesion and accurately marks the location of the lesion, whereas in the case of a deep breast, the black pigment cannot be identified from the outside.
