Embodiment 1

[0075] This embodiment relates to the preparation method of the double-hole pouch retractor of the present invention.

[0076] A kind of preparation method of double hole pouch bag drag hook of the present invention, comprises:

[0077] Step S102, bending the suture so that the suture forms an arc-shaped end;

[0078] Step S104, heating the arc-shaped end to shape the arc-shaped end;

[0079] Step S106, heating the first end of the suture and the second end of the suture, so that the first end of the suture forms a blunt end, and the second end of the suture forms a blunt end;

[0080] Step S108, respectively clamping the blunt ends so that the blunt ends form round ends;

[0081] Step S110, respectively puncturing the circular ends so that the circular ends form through holes.

[0082] In step S104, heating the arc-shaped end includes:

[0083] Use a coagulator to cauterize the arc-shaped end for 3-5 seconds.

[0084] In step S106, heating the first end of the suture and...

Embodiment 2

[0100] This embodiment relates to the double-hole pouch retractor of the present invention, which is made by the preparation method of Embodiment 1.

[0101] An exemplary embodiment of the present invention, such as figure 1 As shown, a double-hole pouch pull hook 100 includes a hook body 110 , a connecting end 120 and a through hole 130 , wherein the connecting end 120 is connected to at least one end of the hook body 110 , and the through hole 130 is set through the connecting end 120 .

[0102] Wherein, the double-hole bladder hook 100 is integrally formed.

[0103] Wherein, the double-hole pouch puller 100 is made of 4-0 polypropylene suture.

[0104] Such as figure 2 As shown, the hook body 110 includes a first hook body 111, a second hook body 112, and a third hook body 113, wherein the hook body 110 is integrally formed, and the first end of the second hook body 112 is connected to the first end of the first hook body 111. The two ends are connected, and the first e...

Embodiment 3

[0131] This embodiment relates to the double-hole pouch retractor device of the present invention, including the double-hole pouch retractor described in Embodiment 2.

[0132] Such as figure 2 As shown, the dual-hole pouch retractor device includes a dual-hole pouch retractor 100 , a suture 200 , a threader 300 and a needle 400 .

[0133] The suture 200 is detachably connected to the double-hole pouch drawer 100 through the through hole 130 . Specifically, one end of the suture 200 is detachably connected to the hook body 110 after passing through the through hole 130 .

[0134]Wherein, the diameter of the suture 200 is smaller than the diameter of the through hole 130 .

[0135] Wherein, the suture 200 is an 8-0 polypropylene suture.

[0136] The threader 300 is detachably connected with the suture 200 and is used to drive one end of the suture 200 through the through hole 130 .

[0137] Wherein, the threader 300 is medical tweezers.

[0138] In some of these embodimen...

Abstract

The invention relates to a double-hole capsular bag drag hook and a preparation method thereof. The preparation method comprises the steps that a suture line is bent so that the suture line can form an arc-shaped end; the arc-shaped end is heated to achieve a fixed form; a first end of the suture and a second end of the suture are heated to enable the first end of the suture to form a round and blunt end and the second end of the suture to form a round and blunt end; the round and blunt ends are clamped respectively, so that the round and blunt ends form round ends; and the round ends are respectively punctured so that through holes are formed in the round ends. The double-hole bag drag hook has the advantages that one through hole and one suture of the double-hole bag drag hook form a lantern ring structure, the tightness is adjustable, and smoothness is achieved; the other through hole of the double-hole capsular bag drag hook is connected with another suture, so that the fixing stability of an artificial lens at the horizontal position is improved, the tension of a capsular membrane at an equator part is increased, and the suture is equivalent to a tension ring but is simpler, adjustable and low in cost compared with the tension ring; and the double-hole capsular bag drag hook does not need to penetrate through the equator capsular membrane to manufacture sclera flaps, and the problems that the artificial lens is not stable in fixation, slips and is large in damage are solved.

Description

technical field [0001] The invention relates to the technical field of scleral fixation, in particular to a double-hole capsular bag retractor and a preparation method thereof. Background technique [0002] Various temporary or permanent capsular bag retractors or fixers implanted in the eye, one end supports and fixes the lens capsular bag under the anterior capsule opening, and the other end is fixed between the scleral layers to reset the subluxed lens or intraocular lens capsular bag complex. Representative capsular bag retractors for permanent intraocular implantation include: anchor-type capsular bag retractors fixed by scleral sutures of PMMA material designed by TonY et al., capsular bags of nylon material fixed by bioglue sclera designed by Jacob S et al. Retractors, T-shaped capsular bag retractors made of polypropylene material fixed between the scleral layers made by Yaguchi S, etc. [0003] The traditional solution is to use 10-0 polypropylene suture to fix the...
