Example 2

Referring to fig. 2 to 6, an incision spreader for surgery includes an elastic opening and closing component 100, a connecting component 200 and a spreading component 300, wherein the elastic opening and closing component 100 is used for elastically spreading the spreading component 300, the connecting component 200 is used for connecting the elastic opening and closing component with the spreading component 300, and the spreading component 300 extends into a wound to spread the wound.

The support rod 110 is provided with a through hole 112, the through hole 112 is internally inserted with a threaded column 150, the threaded column 150 is in clearance fit with the through hole 112, and the through hole 112 prevents the threaded column 150 from obstructing the opening of the support rod 110.

A nut 160 is rotatably connected to each end of the threaded post 150.

A compression spring 170 is sleeved on the surface of the threaded post 150, and the compression spring 170 is arranged between the nut 160 and the support rod 110.

Because the size of wound is different, when the elasticity that the bracing piece 110 received strutted power is great, torn the wound easily, and when finding unsuitable after using this model, generally need change other models that strut power littleer, will take out this device and put into new other models again, the operation is complicated and can cause the waste. In this case, after the nut 160 is screwed, the two sets of support rods 110 can be pressed tightly by the compression spring 170, and the pressing force of the compression spring 170 on the support rods is smaller than the opening force of the torsion spring 130 on the support rods, so that the support rods 110 can be opened for the wound, and the wound cannot be opened too much to be torn, thereby adjusting the opening size of the opening assembly 300.

In the same operation, when the wound needs to be expanded to a larger size, the nut 160 is only required to be unscrewed, and the pressure of the support rod 110 on the two sides is reduced, so that the support rod can be continuously expanded outwards by the torsion spring 130, and the wound is expanded to a larger size.
