Tension ring capable of suturing lens capsular bag

Abstract

The invention discloses a tension ring capable of suturing a lens capsular bag. The tension ring comprises a semi-open elastic ring. An elastic loop is arranged in the middle of the elastic ring along the arc length direction. The elastic loop is positioned on the inner side of the elastic ring. The elastic loop comprises a front branch and a sewing branch which are both in a curve shape and are smoothly connected. The tangent circle of the front branch and the tangent circle of the suture branch are respectively positioned on different sides of the elastic loop. The sewing branch is close to the elastic ring towards the tangent circle side. The front branch is smoothly connected with the elastic ring. According to the tension ring capable of suturing the lens capsular bag, by means of the bending shape, elasticity and deformation trend of the elastic loop, when the tension ring is implanted into the eye of a patient, bending deformation of the elastic loop is automatically achieved according to the borne external force so as to reduce the height of the elastic loop, so that implantation resistance is reduced, the tension ring can be implanted into the eye of the patient before and after cataract emulsification and removal of nucleus blocks and cortex, the cataract surgery can be smoothly completed, and the position of the intraocular lens can be ensured to be neutral after the surgery.

Description

technical field [0001] The invention relates to the field of tension rings, in particular to a suturable lens capsular bag tension ring. Background technique [0002] The suturable capsular bag tension ring is a lens capsular bag implant that can restore the physiological characteristics of the lens capsular bag when the lens is dislocated; it can help the intraocular lens to be implanted smoothly and positioned and supported. The timing of implanting the lens capsular tension ring depends on the patient’s surgical needs. For example, sometimes it needs to be implanted before aspiration of the cataract nucleus and cortex, and sometimes it needs to be implanted after or during the aspiration of the nucleus and cortex. [0003] In the prior art, for the suture-fixable capsular tension ring, it includes a C-shaped ring body and a suture loop connected to the ring body and located inside the ring body. The suture loops are also in the shape of a "C". Therefore, no matter in whi...
