The movable leg moves in a smaller range, thereby facilitating quick and accurate adjustment of the size of the opening of the surgical site. The device can accurately and stably expand the surgical site of the patient, making it convenient for medical staff to perform surgical treatment on the patient and improving the efficiency of the operation.

[0013] 2. By setting the adjusting leg to be rotatably connected to the connecting leg through the connecting shaft, it is convenient to flexibly adjust the angle of the support plate, so that the operator can adjust the support plate to a suitable angle, which is convenient for providing a larger field of view for the operation. By setting the sliding sleeve to be connected to the adjusting leg for sliding up and down, it is convenient to adjust the length of the entire expansion assembly, so as to facilitate flexible adjustment according to the depth of the surgical site, which greatly improves the expansion effect. Moreover, by setting the L-shaped structure between the support plate and the sliding sleeve, it will not block the operator's line of sight, thereby improving the efficiency of the operation.

[0014] 3. By distributing the support plate obliquely, it is easier to open the surgical site, and by providing convex strips, the friction between the support plate and the surgical site is increased, making the contact between the support plate and the surgical site more stable.
