Embodiments of the present application provide a blood vessel type recognition method, device and electronic equipment. The blood vessel type recognition method comprises: obtaining a DSA sequence in DICOM format, obtaining pixel data and body position information according to the DSA sequence, and the sequence frame in the pixel data is in single-channel format; obtaining a pixel feature from the sequence frame and an angle feature from the body position information; fusing the pixel feature and the angle feature to obtain a fused feature; and outputting a blood vessel type according to the fused feature. In the embodiments of the present application, the pixel data and the body position information are obtained from the DSA sequence in DICOM format, then the pixel feature is obtained from the sequence frame and the angle feature is obtained from the body position information, and after the fused feature is obtained, the blood vessel type is output according to the fused feature. Compared with the blood vessel type recognition method in the related art which relies on the subjective recognition of doctors, the blood vessel type recognition method in the embodiments of the present application can more objectively determine the blood vessel type, and has higher efficiency and accuracy.

The utility model belongs to the field of ophthalmic operation tool, especially be related to a forceps for pterygium excision. The technology includes two handle, the end of two handle is hinged to each other, is provided with drive assembly between two handle, is provided with locking assembly between two handle, is fixed with clamping part on the hinged end of two handle, the clamping part includes two arc clamping rods, is fixed with straight line clamping rod between the opposite end of two arc clamping rods, the other end of one arc clamping rod is fixed with support rod, support rod is fixed on handle, and the clamping part whole presents hook shape. The clamping part of hook shape structure is small, and the shape is more adaptive to the operation area of eye, can clamp the blood vessel tissue of whole pterygium excision site once, is more convenient to clamp operation, need not adjust orientation and clamp several times, two arc clamping rods and straight line clamping rod combination present boat type, are more adaptive to the shape of lacrimal caruncle area, and the resection along the clamping trace is more beautiful.
