In addition, the steps of skin incision, insertion of a trocar and suturing of the skin after intra-abdominal operation are performed under two-dimensional visual straight view, so there is a situation of switching between 2D and 3D vision during the operation. Since the lenses of the 3D glasses are gray-black, the visual effect of the operator will be affected if the 3D glasses are not taken off.

[0004] Currently, there are the following problems in taking off and wearing 3D glasses for the operator: (1) all medical staff participating in the operation on the operating table cannot take off and wear non-sterile 3D glasses by themselves after wearing sterile surgical clothes and sterile gloves, and need the assistance of other personnel under the operating table; (2) due to the influence of masks and surgical caps, the 3D glasses are easily worn unstably and fall to the sterile table surface, causing pollution of the sterile table surface; (3) the sterile surgical clothes of the operator are easily touched during the process of taking off and wearing 3D glasses, causing pollution of the sterile surgical clothes; (4) for the operator who wears myopia glasses, the 3D glasses need to be worn outside the myopia glasses, which makes it more difficult to wear and the wearing comfort is poor, affecting the 3D vision and the normal development of the operation.
