Abstract
The utility model discloses a lens loop guiding needle for scleral interlayer fixation intraocular lens suspension surgery, which comprises a needle seat and a needle body; the needle body comprises a front part and a rear part; the front part and the rear part form an angle of 120-150 degrees; the front part is provided with a needle hole and a needle hole. The crystal loop guiding needle of the utility model designs the needle body into a front part and a rear part which form a certain angle, thus being capable of conforming to the radian of human eyeball and being convenient for the operation of an operator; meanwhile, the needle body is provided with the needle hole, so that the artificial lens loop can be conveniently led out, the artificial lens loop is prevented from being excessively bent, and the price is cheaper than that of the retinal forceps.
Description
Technical Field
The utility model belongs to the technical field of medical instrument, concretely relates to fixed intraocular lens suspends art in midair between scleral layer and uses crystal tong "pan" guide needle.
Background
In the case of clinically insufficient posterior capsular sac support after traumatic cataract, after lens cutting, after intracapsular cataract extraction, etc., the posterior chamber type intraocular lens implantation needs to be performed with ciliary sulcus intraocular lens suture suspension fixation. During the operation, the intraocular lens needs to be fixed by using a suture, if the suture is only covered by a bulbar conjunctiva, the conjunctiva can be penetrated by the suture knot for a long time, and the intraocular infection at a later stage is easy to cause or the suture falls off for a long time to cause the intraocular lens to fall into a vitreous cavity. In addition, the artificial ciliary sulcus lens suture suspension technology is used for fixing the artificial ciliary sulcus lens at two points, so that the stability of the artificial ciliary sulcus lens is poor, and the artificial ciliary sulcus lens is easy to incline. Therefore, posterior chamber intraocular lens scleral sutureless fixation (also called scleral fixation intraocular lens suspension) has been developed clinically.
In the operation, a 23G puncture knife needs to be used for puncturing a sclera flap 2mm behind a limbus at 3 points and 9 points respectively, the sclera flap enters a posterior chamber of an eye, an intraocular lens is folded in half and then is sent into the anterior chamber from a 12-point angle sclera tunnel incision, a posterior loop is left outside the incision, a retinal forceps enters from a puncture port at the 3 point position, enters the anterior chamber through a posterior chamber and a pupil, clamps a front loop of the intraocular lens, pulls out the puncture port, and pulls out the posterior loop from the puncture port at the 9 point position.
However, the artificial lens loop needs to be clamped by the retinal forceps in the operation, if the artificial lens loop is repeatedly clamped, the lens loop is easy to break, so that iatrogenic intraocular foreign bodies are caused, and in addition, the retinal forceps are expensive, so that the operation cost of a patient is high.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the problems and provide a lens loop guiding needle for scleral layer fixing intraocular lens suspension surgery for replacing retina forceps.
Realize the utility model discloses the technical scheme of purpose is: a lens loop guiding needle for scleral interlayer fixation intraocular lens suspension comprises a needle seat and a needle body; the needle body comprises a front part and a rear part; the front part and the rear part form an angle of 120-150 degrees; the front part is provided with a needle hole and a needle hole.
The front and rear portions are preferably 135 ° apart.
The utility model discloses positive effect that has: (1) the utility model discloses a crystal tong "pan" guide needle designs into the needle body and is two parts around certain angle, can accord with the radian of human eyeball like this, and the art person of being convenient for operates. (2) The utility model discloses a crystal tong guide needle is equipped with the pinhole on the needle body, can make things convenient for drawing forth of artificial crystal tong like this, avoids the excessive tortuous of artificial crystal tong, and the price is compared in retina tweezers more cheaply moreover.
Drawings
Fig. 1 is a schematic structural diagram of a loop of crystalloid guiding needle of the present invention.
Fig. 2 is a top view of fig. 1.
Detailed Description
Referring to fig. 1 and 2, the present invention provides a needle for guiding a loop of a lens, which comprises a needle holder 1 and a needle body 2.
The needle body 2 comprises a front portion 21 and a rear portion 22, with an angle of 135 between the front portion 21 and the rear portion 22.
The front portion 21 is provided with an eye 211 and a hole 212.
The needle body of the crystal loop guiding needle is designed into a front part and a rear part which form a certain angle, so that the needle body can conform to the radian of the eyeball of a human body, and the operation of an operator is facilitated; and the needle body is provided with the needle hole, so that the artificial lens loop can be conveniently led out, the artificial lens loop is prevented from being excessively bent, and the price is cheaper than that of the retinal forceps.
Claims (2)
1. A lens loop guiding needle for scleral interlayer fixation intraocular lens suspension is characterized in that: comprises a needle seat (1) and a needle body (2); the needle body (2) comprises a front part (21) and a rear part (22); the angle between the front part (21) and the rear part (22) is 120-150 degrees; the front part (21) is provided with a pinhole (211) and a pinhole (212).
