Problems solved by technology

[0003] Therefore, the present invention overcomes the defects in the prior art that the folding of extraocular muscles in the treatment of strabismus takes a long time and is inefficient, and the initial suture is not firm enough to cause recurrence, and the needle is prone to penetrate too deeply into the inner wall of the eyeball and cause retinal tears. , to provide an ophthalmic suturing device that can improve the suture quality and suture efficiency of strabismus surgery, and reduce retinal breaks due to needle insertion

Abstract

The invention relates to the technical field of medical instruments, in particular to an ophthalmic stapler and an application method thereof. The ophthalmic stapler comprises a fist clamping piece, asecond clamping piece and a lead structure, wherein the second clamping piece is arranged opposite to the first clamping piece; clamping parts of the first clamping piece and the second clamping piece are provided with clamping positions close to each other and opening positions far away from each other; the lead structure comprises a lead piece arranged on the first clamping piece and / or the second clamping piece, and a slot formed in the first clamping piece and / or the second clamping piece, and the lead structure is connected with the lead piece and the slot in a matched and inserted mode;and the lead piece is provided with an open hole for sutures to penetrate through. The invention provides an ophthalmic stapler which can improve the surgical suture quality and suture efficiency ofthe strabismus surgery and reduce sclera perforation caused by needle insertion.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an ophthalmic stapler and a using method thereof. Background technique [0002] Strabismus refers to any clinical phenomenon in which the axes of the eyes deviate from parallel, which may be caused by abnormal nerve fusion mechanism or 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 vision development, cause amblyopia, and also have adverse effects on children's psychology. In terms of treatment, strabismus is mostly treated with surgery. In order to adjust the position of the eyeball, the patient can achieve the purpose of seeing things with both eyes at the same time and restore the patient's three-dimensional function. Surgical methods for strabismus vary by type. But the principle is basically the same, mostly...
