[0032] As a preferred embodiment, the leading end of the isosceles triangular plate 2 is provided as an arc-shaped leading end 21, and the arc-shaped leading end 21 is used for exposing the surgical field of view.
[0033] By providing the leading end of the isosceles triangular plate 2 as the arc-shaped leading end 21, the arc-shaped leading end 21 is beneficial to exposing the surgical field of view during the operation, and reduces the auxiliary injury caused by the shielding of the isosceles triangular plate 2.
[0034] Further, the curvature of the arc-shaped leading end 21 is 20-30°. By limiting the curvature of the arc-shaped leading end 21, the effect of exposing the surgical field of view during the operation is ensured.
[0035] As a preferred embodiment, the edges of the isosceles triangular plate 2 are all provided as R chamfers 22. By providing the edges of the isosceles triangular plate 2 as the R chamfers 22, the auxiliary injury caused by the edges of the isosceles triangular plate 2 is reduced.

Therefore, the arc-shaped boss I 25 is integrally arranged at the middle position of the upper end surface of the isosceles triangular plate 2, so that when the isosceles triangular plate 2 is lifted upward, the upper end surface of the isosceles triangular plate 2 simultaneously contacts the tissue through the arc-shaped boss I 25, the acting force applied by the isosceles triangular plate 2 when lifted upward is dispersed, and secondary injury is avoided. Similarly, when the isosceles triangular plate 2 is pressed down, the lower end surface of the isosceles triangular plate 2 first contacts the tissue, and the pressing force is applied to the tissue by the lower end surface of the isosceles triangular plate 2, so that secondary injury is easily caused. Therefore, the arc-shaped boss II 26 is integrally arranged at the middle position of the lower end surface of the isosceles triangular plate 2, so that when the isosceles triangular plate 2 is pressed down, the lower end surface of the isosceles triangular plate 2 simultaneously contacts the tissue through the arc-shaped boss II 26, the acting force applied by the isosceles triangular plate 2 when pressed down is dispersed, and secondary injury is avoided.
