Abstract

The invention discloses a novel degradable biological amniotic membrane composite lacrimal passage repair stent which comprises a stent body. The stent body comprises a composite inner core and an amniotic membrane tegment; the amniotic membrane tegment is wound on the composite inner core to form at least one pointed end; the composite inner core is formed by twisting at least one strand of amniotic membrane core and at least one strand of medical suture; one end of one strand of medical suture penetrates out of the pointed end. The novel degradable biological amniotic membrane composite lacrimal passage repair stent solves the key problem of smooth healing of a lacrimal ductule, has the effects of promoting repairing and healing of the mucous epithelium of a lacrimal passage, reducing scars, reducing inflammation and preventing re-adhesion, enables biological activity of the amniotic membrane to be kept and prolonged, can meet the requirement of clinical application for degrading time, enables a normal anatomy function of the lacrimal ductule to be recovered, does not need external force for extirpation and cannot cause secondary damage.

Description

technical field

[0001] The invention relates to the technical field of biomedicine, in particular to a novel lacrimal duct repair bracket composed of degradable bio-amnion. 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. Simple dredging, if there is no support to keep the lacrimal duct lumen expanded after lacrimal duct laser and high-frequency electrotherapy, the postoperative wound surface is not completely cured due to reactive edema or original chronic inflammation, and the lacrimal duct lumen is easily closed. Adhesion of the cavity wall, followed by tissue repair wound adhesion and healing, resulting in reocclusion of the lacrimal duct lumen. Lacrimal duct s...
