[0030] 2. The transumbilical costal cartilage high-power scissors of the present invention utilize an opening pin to actively open the left and right scissor blades, thereby avoiding the problem that the shear heads cannot be opened by a spring due to pressure from the surrounding tissues of the costal cartilage such as chest skin, and the like.

[0031] 4. The left and right scissor blades of the transumbilical costal cartilage shears of the present invention are respectively provided with a left pressing edge and a right pressing edge on the outer side walls that are in sliding contact with the pressing inclined surface.

[0032] 5. The shearing plane of the transumbilical costal cartilage scissors of the present invention is designed to be at an angle of almost 90° to the handle, so that when the hand holds the handle in the functional position, the scissor head is just perpendicular to the costal cartilage.
