Therefore, this section of carrying arm is made into a cylindrical shape. When in use, directly pull the second carrying arm 2 and hold it The position is more comfortable, and it can also prevent the second carrying arm 2 from causing cuts to the opponent, and it is safer to use.

The specific working process of the surgical spreader is as follows: the edge of the incision is pre-placed with gauze to reduce the pressure of the tongue plate on the tissues near the incision. According to actual needs, the first tongue plate 3 and the second tongue plate 4 are twisted at a certain angle, so that the first bearing arm 1 and the second bearing arm 2 do not obstruct the entrance of the cutout. After the angle is adjusted, the first tongue plate 3 is inserted under the pectoralis major, and the front end of the second tongue plate 4 is placed near the midaxillary line. Continue to reversely pull the handle 8 and the second carrying arm 2 so that the entrance of the cutout is exposed clearly, and then insert the bayonet pin into the through hole to fix the length of the supporting arm 5 . As the opening angle of the spreader increases, the free arm 7 slides in the direction of the second tongue plate 4, and engages step by step with the saw-toothed inverted teeth 9 on the inner surface of the second bearing arm 2, so that the spreader can be in a fixed position. Angle open state. Stop pulling the handle 8 when the outer slit reaches the maximum open state. At this time, the operator can easily push the prosthesis into the entrance of the tunnel and advance it deep. After the prosthesis is placed, the bayonet is removed, the support arm 5 is shortened, the opening angle of the spreader is reduced, and the spreader is withdrawn from the tunnel.

The use of this spreader simplifies the prosthesis insertion process, reduces the surgical intensity, and one person can complete all surgical operations, and the curling of the edge of the tongue plate can effectively prevent sharp cutting injuries to the prosthesis or the incision. In other operations that need to open and fix the incision, the utility model can also conveniently realize the function of stretching and fixing.
