These tweezers are used for, and isolating " cutting edge of a knife or a sword mouth " position (lateral border) is not for opening the sharp edges behind the cutting edge of a knife or a sword, but laminate structure that has arc edge, when separating, the operation passivity can not cause the cutting damage of sharp property like this to retina, the head of tweezers is to have certain tip design, is not round completely dull face.The effect of cutting-edge structure design mainly is the tight adhesion that is used for fully separating between retina and the propagation film, by thrusting between retina and the propagation film of tip, from shallow to deep progressively insertion and separation of synechia are that retina is bred between the film the tight tight of adhesion to the initial position of the operation that the space is arranged.
First, these tweezers are a horizontal force along retinal surface what carry out producing when passivity is separated, firmly position during separation should be on the retina tangent plane, and the longitudinal force of non-perpendicular retinal surface, and isolating radius amplitude is less in the operating process, has reduced amphiblestroid traction is disturbed.Second, traditional operation method is that a folk prescription is to the strip of exerting oneself when divesting the propagation film, what produce on retina is a unidirectional traction force, lack a kind of counteractive " resistance power ", easily cause the closely retina generation " displacement " at place of adhesion, easily retina is caused the mechanicalness stretch injury.And inactive separated forceps is in separation process, what produce on retina then is two-way function power, relation for a pair of active force and counteracting force, the retina both sides are symmetrically stressed, reach equilibrium of forces, rely on the influence of retroaction " resistance power ", make retina " displacement " can not take place, avoided amphiblestroid mechanical injuries.The 3rd, the isolating purpose of passivity is divested as the direct film of will breeding of stripping, but be used to separate retina and the adhesion of breeding film, to expand as little space by the tight tight of adhesion between the two, expand as big space by little space, separates two tissue progressively forms the gap of " tunnel sample ", and by cutting or wipe out and obtain loosening of propagation film.
The material of these tweezers adopts titanium alloy, has the good mechanical performance and organizes inertia, can make the operating time of complicated VI phase patients with diabetic retinopathy be reduced in 1 hour and finish.
The utility model has the advantages that: avoided retinal rupture in the art, hemorrhage generation, simplified operation technique greatly, saved operating time, improved operative effect, greatly saved the forfeiture of postoperative visual function.
