Abstract

The invention provides an amniotic-membrane lacrimal passage repair support which comprises an amniotic-membrane support body made from an amniotic membrane subjected to freeze drying treatment and amedical suture connected to two ends of the amniotic-membrane support body. The length of the amniotic-membrane support body between two suture nodes is slightly larger than the length of the medicalsuture between the two ends of the amniotic-membrane support body. During traction of the amniotic-membrane lacrimal passage repair support, the amniotic-membrane support body is not stressed, it is ensured that the amniotic-membrane lacrimal passage repair support does not break in the lacrimal passage, easily adapts to a zigzag structure of the lacrimal passage, secondary blockage caused by thefact that pulling friction causes damage and adhesion of the lacrimal passage tissues, and meanwhile the amniotic-membrane support body has the very good treating effect on lesion tissues, is conductive to restoration of the epithelium structure and functions of the lacrimal passage, prevents scar formation and is high in efficiency, good in long-term effect and low in relapse rate. The amniotic-membrane support body can be degraded after being implanted without reoperation for removal, can be stored at normal temperature for a long time, is convenient to transport and can meet the clinic demand at any time.

Description

technical field

[0001] The invention relates to the technical field of biomedicine, in particular to an amniotic lacrimal duct repair bracket and a manufacturing method thereof. Background technique

[0002] Lacrimal duct obstruction diseases (LDOD) refer to a group of diseases caused by various reasons, with lacrimal duct obstruction as the pathological feature and epiphora as the main clinical manifestation. It is a common and frequently-occurring disease in ophthalmology. Cystic anastomosis and probing of the punctum lacrimal duct. innocent sparse If there is no support to keep the lacrimal duct cavity expanded after lacrimal duct laser and high-frequency electrotherapy, the postoperative wound surface is not completely healed due to reactive edema or original chronic inflammation, and the lacrimal duct lumen is easily closed and the cavity wall is adhered. , and then tissue repair wound adhesion, resulting in re-occlusion of the lacrimal duct lumen. In laser or in hig...
