As shown in FIG. 5, the skin normally has an epidermis 51, a dermis 52, a subcutaneous tissue, and a subcutaneous fat 53 arranged in layers from the outside in order. When performing a suture operation, the suture 56 must be sutured together with the subcutaneous tissue and the subcutaneous fat 53.
When performing sutures, the surgeon should use the prosthesis so that the incision is visible, to avoid damage to the subcutaneous organs, blood vessels, and nerves, and to prevent the incision from shifting. Often, the incision is lifted and sutured.

FIG. 6 shows an example of a raising part conventionally used in a suture operation.
The surgeon slightly lifts the incision 55 using the raising element as shown in FIG. 6 so that the epidermis 22, the dermis 23, the subcutaneous tissue, and the subcutaneous fat 24 correspond to each other without deviation as shown in FIG. 5. Then, the suture thread 56 is passed through while visually observing the inside of the incision portion, and is tied at the knot 57.

Along with the rapid changes in modern lifestyle habits, the number of patients with metabolic syndrome has been increasing rapidly. It is difficult to lift the part and see the internal state.
In addition, it is difficult to see the internal state of the incision even when the incision has a small opening, such as when the normal suture operation is nearing the end stage, or in the case of low invasive endoscopic surgery. It has become.
For this reason, in a suturing operation, it has been desired to provide a raising element that allows the incision to be lifted from the inside by a simple operation and can be sutured efficiently and safely while looking at the section of the incision.
