Description

A patch for lesion localization

technical field

The invention relates to a positioning tool for human body tissue surface for surgical incisions, which is widely used in the positioning of incisions before surgical operations, such as craniocerebral lesions, torso (chest, abdomen) and extremities surgical incision positioning, including kidneys, livers and other substantive organs in the body. Organ biopsy, removal of foreign bodies in the body, etc.

Background technique

In the clinical operation of patients, since most of the lesions are located in the human body under the skin, the specific location cannot be directly determined by the naked eye, and the location depends on preoperative X-ray or CT examination. Therefore, the current treatment method is to take X-ray photos of the lesions before the operation. During the operation, refer to the X-rays taken to determine the location of the lesion and determine the incision for the operation. But the problem with this method is that since the doctor needs to find the location of the lesion through X-rays, and there is no corresponding positioning reference on the X-rays and the patient's body surface to accurately locate the doctor, the doctor can only use visual X-rays. X-rays are used to roughly estimate the positioning on the patient. At the same time, due to factors such as the position of the patient when shooting the X-rays, the distance between the patient and the machine, and other factors, the magnification of each X-ray is different. It makes it more difficult for the doctor to accurately locate the lesion, and the error is large. The doctor may need to make a larger incision to find the location of the lesion during the operation, or make a smaller incision than the actual need during the operation and need to re-open. A large incision often increases the patient's surgical trauma during the operation, and also easily increases the patient's bleeding during the operation, which not only leads to prolonged operation time, but also increases the patient's pain, which is not conducive to the patient's prognosis and recovery.
