Definitions
- the present invention relates to a tissue ablation apparatus and a tissue ablation system, and in particular, the presence and absence of blood vessels through tissue internal structure images to be removed by line scanning the human tissue without mounting a camera module in a portion inserted into the human body.
- the present invention relates to a tissue ablation apparatus and a tissue ablation system capable of observing size directly with an eye and minimizing damage due to unintended vascular ablation during surgery.
- surgery refers to repairing a disease by cutting, slitting, or manipulating skin, mucous membranes, or other tissues with a medical device.
- Open surgery during this operation corresponds to surgery to split the abdominal cavity or the skin of the face (skin), and to treat, shape or remove the organs therein.
- the skin When performing such open surgery, the skin is incised so that a predetermined space is formed between the skin and the tissue, and then a surgical operation is performed through the space, resulting in a lot of wounds and slow healing after surgery. Recently, laparoscopic surgery has attracted attention as an alternative.
- Laparoscopic surgery is performed by observing the intraperitoneal surgical site by inserting a laparoscope through a small hole in the surgical site of the patient, and is widely used in various medical and surgical operations, urology and obstetrics and gynecology.
