The present invention relates to a surgical retractor, and more particularly to a surgical retractor with an illumination portion that can fix the incision during surgery and illuminate the affected area.

In general, a retractor is a medical technology for cutting the patient's skin and fixing the incision site during surgery, there are various types of retractors according to the type of surgery.

In general, in the case of a surgical operation, the lighting device fixed to the ceiling of the operating room or a separate lighting device that can change the position of the operating assistant uses a separate lighting device, in order to perform the procedure deep into the affected area at the time of surgery to change the lighting unit by the assistant There is an inconvenience to be given.

In addition, surgical methods for gradually reducing the incision area have been introduced in order to minimize patient scarring and skin scarring.

As the incision becomes smaller, the lighting device fixed to the ceiling of the operating room or the lighting device by the assistant cannot be illuminated, or there are many inconveniences in lighting due to many inconveniences in surgery.

To overcome this, retractors with lighting units have been known in recent years.

Figure 1 shows a retractor with a lighting device attached to the blade as in the Republic of Korea Utility Model Model Publication No. 20-0182997, a representative view.
