More particularly, the present invention relates to a surgical retractor for mandibular angle resection, which can prevent nerve and blood vessel damage caused by teeth of a saw in the case of cutting a mandibular bone by inserting the saw behind the ear. According to an embodiment of the present invention, a surgical retractor for mandibular angle resection comprises: a first deviation preventing part which prevents the teeth of a saw from deviating to the inside jawbone, wherein the teeth of the saw is located inside the jawbone of a patient while being inserted behind the ear of the patient, and cuts the jawbone of the patient; and a second deviation preventing part protruding to the upper side from the front end of the first deviation preventing part, and preventing the teeth of the saw from deviating to the front of the jawbone and to the sides of the jawbone.

Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a retractor for mandibular angle resection preventing vessel and nerve damage,

More particularly, the present invention relates to a retractor for a square jaw surgery, which can prevent nerve and vascular damage due to a saw blade when a saw blade is inserted behind an ear to cut a square jaw .

A so-called quadriceps jaw surgery is a procedure in which an incision about 3 cm is cut about the back of the ear to remove the mandibular protrusion and then trimmed. This type of posterior jaw surgery does not require general anesthesia. It has advantages of quick recovery, minimization of bleeding and swelling, and excellent accessibility to the area of the jaw surgery because it approaches the mandible with a small incision behind the ear.

On the other hand, caution must be exercised to prevent damage to the surrounding of the mandible, especially the inner, outer, and lower sides of the mandible, which may be fatal to the patient during injury.

However, it is not easy to freely stop the saw blades that are osteotomized because of the nature of the square jaw surgery. When the osteotomy of the jaw is completed with a lot of downward force applied to the saw blade, In some cases, damage to the blood vessels occurs, or in the course of surgery, the saw blade is pushed forward or excessively forward, leading to damage to soft tissues, blood vessels and nerves.

Recently, in order to prevent damage of muscles, nerves, blood vessels, etc., the saw blade used for osteotomy of the mandible is used to insert the gauze into the inner side and the lower side of the mandible and to perform mandibular osteotomy. In other words, before putting the gauze inside and below the mandible, the gauze blocks the progress of the saw blade even if the saw blade used for the mandibular osteotomy moves away from the mandible, thereby preventing damage to muscles, blood vessels and nerves .

However, there are the following problems in the case of osteotomy of the mandible in this manner.

That is, even if the gauze is removed after completing the mandibular incision, the gauze is not completely separated and the by-product of the gauze remains in the vicinity of the mandible, so that it is troublesome to remove the gauze, and if the gauze by- , There is a problem that aftereffects that cause inflammation in the surgical site occur.

In addition, it is impossible to completely protect the periphery of the mandible using the gauze itself, and there is a problem in that residual gauze can not be avoided if the gauze is damaged by the surgical saw blade.
