Background

In cataract surgery, forceps are usually used, and after the tunnel incision is made in the sclera of the outer corner, the lens is held by the forceps, and is inserted into the lens capsule from the incision, forming an angle of 90 degrees with the eye from the top. In the operation process, one hand is needed to clamp a conjunctiva by using tweezers, the other hand is used to stretch the crystal from the corneal incision at the middle edge positions of the two sides of an eyeball by using a crystal positioning hook, the crystal is gently shifted to be rotated or translated from the original deviated position to the appointed position, and the crystal loop exposed outside the capsule completely enters the capsule. If necessary, the central part of the crystal is slightly pressed from above by an iris restorer to enter the capsular bag.

However, the existing surgical implantation forceps have the following defects: 1 to facilitate the holding of the artificial lens, the end of the forceps is pointed, and although passivation is performed, the forceps are still sharp relative to the posterior capsule during the holding process, which is likely to cause the rupture of the posterior capsule. 2 the handle elasticity of tweezers is poor, has the problem of pressing from both sides and get unstably. 3 different doctors have different hand holding powers, and in the operation process, the artificial lens is not buffered, and is easy to damage due to uneven holding power.
