眼科缝合器及其使用方法Ophthalmic stapler and method of use

技术领域technical field

本发明涉及医疗器械技术领域，具体涉及一种眼科缝合器及其使用方法。The invention relates to the technical field of medical devices, in particular to an ophthalmic stapler and a method for using the same.

背景技术Background technique

斜视是指任何眼轴偏离平行的临床现象，因神经融合机制异常或者控制眼球运动的神经眼外肌异常等可能原因引起，斜视会对患者的立体功能和外观造成影响。斜视常于儿童期发病，严重的斜视会影响儿童的视力发育，引起弱视，也会对儿童的心理造成不良的影响。治疗方面，斜视多采用手术方式进行治疗，为调整眼球位置，使患者达到双眼同时视物的目的，恢复患者的立体功能。斜视手术方式因类型的不同而异。但其原理基本一致，大多是通过改变眼外肌在眼球附着点的位置，减弱斜视方向眼外肌的力量。同时在对应的方向进行眼外肌截除或折叠的方式，加强眼外肌力量从而使双眼位置最终达到平行。加强对应眼外肌的力量方面，现有手术方式，利用角规测量所需折叠的眼外肌长度，手工缝合固定眼外肌，所需时间较长，缝合固定时存在眼外肌固定不牢固，易出现眼外肌滑脱导致斜视复发，同时易出现进针过深，穿入眼球内壁，导致视网膜裂孔的风险。Strabismus refers to any clinical phenomenon in which the axis of the eye deviates from the parallel. It may be caused by abnormal neural fusion mechanism or abnormality of the nerve extraocular muscles that control eye movement. Strabismus will affect the patient's stereoscopic function and appearance. Strabismus often occurs in childhood. Severe strabismus will affect children's visual development, cause amblyopia, and also have adverse effects on children's psychology. In terms of treatment, strabismus is mostly treated by surgery, in order to adjust the position of the eyeball, so that the patient can achieve the purpose of seeing objects with both eyes at the same time, and restore the patient's three-dimensional function. Strabismus surgery varies by type. But the principle is basically the same, mostly by changing the position of the extraocular muscles at the attachment point of the eyeball, reducing the strength of the extraocular muscles in the direction of strabismus. At the same time, the extraocular muscles are removed or folded in the corresponding direction to strengthen the extraocular muscles so that the positions of the eyes are finally parallel. In terms of strengthening the strength of the corresponding extraocular muscles, the existing surgical methods use angle gauges to measure the length of the extraocular muscles that need to be folded, and fix the extraocular muscles by hand, which takes a long time, and the extraocular muscles are not firmly fixed when sutured and fixed. , It is prone to extraocular muscle slippage leading to recurrence of strabismus, and at the same time, it is prone to needle penetration too deep into the inner wall of the eyeball, leading to the risk of retinal tears.

1. An ophthalmic stapler, comprising:

a first clamp (1);

a second holding member (2) provided opposite to the first holding member (1), the first holding member (1) and the second holding member (2) having holding portions (4) of both thereof: a clamping position close to each other and an open position away from each other;

a lead structure, comprising: the lead wire piece (3) is arranged on the first clamping piece (1) and/or the second clamping piece (2), the slot (5) is arranged on the first clamping piece (1) and/or the second clamping piece (2), and the lead wire piece (3) and the slot (5) are matched and plugged; the lead piece (3) is provided with an opening (6) for a suture to pass through.

2. The ophthalmic stapler according to claim 1, wherein the lead member (3) and the insertion slot (5) are provided on the grip portion (4), and the insertion slot (5) is a through hole penetrating the grip portion (4); in the clamping position, the suture passes through the through hole to a position remote from the grip (4).

3. An ophthalmic stapler according to claim 1 or 2, characterized in that one end portion of the lead member (3) is a spike-like cylindrical structure, and the other end portion of the lead member (3) is a connecting portion connected to the grip portion (4); the opening (6) is arranged at one end of the lead element (3) far away from the connecting part.

4. An ophthalmic stapler according to any of claims 2-3, characterized in that the holding part (4) is provided with a receiving cavity (7) in its length direction, and that adjacent lead elements (3) are connected by means of a connecting element (8) arranged in the receiving cavity (7).

5. An ophthalmic stapler according to any of claims 1-4, characterized in that said lead elements (3) are at least two and are both arranged on said first clamp (1) and said sockets (5) are at least two and are both arranged on said second clamp (2).

6. An ophthalmic stapler according to any of claims 1-5, characterized in that the number of said lead elements (3) is two and that the two lead elements (3) are symmetrically arranged on both sides of the central position of the clamping part (4) of the first clamping element (1) and/or the second clamping element (2).

7. An ophthalmic stapler according to claim 6, characterized in that two said lead elements (3) are arranged close to the centre of the grip portion (4).

8. The ophthalmic stapler according to claim 4, characterized in that the lead element (3) and the connecting element (8) are of one-piece construction.

9. A method of using an ophthalmic stapler of any one of claims 1-8, comprising the steps of:

s1, threading the suture into the lead piece (3);

s2, opening and supporting the eyelid;

s3, driving the first clamping piece (1) and the second clamping piece (2) to the clamping position, thereby folding the extraocular muscle and leading the lead piece (3) to carry the suture thread to pass through the extraocular muscle;

s4, pulling the suture through one end of the extraocular muscle;

s5, driving the first clamping piece (1) and the second clamping piece (2) to the opening position, and taking down the ophthalmological stitching instrument;

and S6, knotting the suture thread remained at the position of the extraocular muscle, thereby fixing the extraocular muscle in a folded manner.
