Stitch scissors for ophthalmology department

Abstract

The invention relates to a pair of stitch scissors for an ophthalmology department and belongs to the field of medical instruments. The stitch scissors comprise two scissors arms which are hinged to each other through a hinge pin. Scissors blades are arranged at the front ends of the scissors arms, rings are arranged at the back ends of the scissors arms, the scissors blades at the front ends of the scissors arms are horizontally arranged in a bent shape, an arc-shaped guide hook is arranged at the front end of one of the scissors blades, an arc-shaped notch is formed in a portion, at the back end of the guide hook, of the scissors blade, and an arc-shaped protruded block corresponding to the notch is arranged on the other scissors blade. According to the stitch scissors, a stitch thread can be guided into the notch quickly and accurately through the guide hook and then be fixed, and therefore the problem that scissors blades can slip easily in the process of stitch removing in the prior art is solved. The stitch scissors can cut off the stitch thread and draw out a stitch thread head through clamping of clamping patterns, therefore, the problem that difficulty of stitch removing operation is increased to a certain degree because a cut stitch thread needs to be drawn out through tools like tweezers in the prior is solved, and the stitch scissors are especially suitable for being used in ophthalmology operation stitch removing.
