Description

Conjunctiva access orbit fat release lacrimal canal filling operation drag hook

Technical Field

The utility model belongs to the technical field of medical appliances, and particularly relates to a conjunctival access orbit fat release lacrimal canal filling operation retractor.

Background

Pouch and lacrimal passage depression deformity is one of the most common causes of clinical paleness around the eyes, and the orbital fat and depressed lacrimal passage bulging into a pouch shape make people look tired. Currently, more and more young people begin to afflict this. Because the skin of young eyes is more elastic than middle-aged and elderly people, the symptoms of the skin are not accompanied with skin relaxation of eyes, the symptoms of lower eye bag bulging and tear duct sinking are clinically improved by conjunctival access eye bag excision and orbital fat release tear duct filling, an incision of 10-12mm is needed to be made on conjunctiva, soft tissues such as meibomian and muscles are pulled by a drag hook, the incision is separated downwards to the orbital bone periosteum at the lower orbital margin, a periosteum stripper is used for separating the superficial periosteum muscle and ligament tissues to form a cavity gap, and the bulged orbital fat is manufactured into a fan-shaped tissue flap to be filled in the tear duct sinking position.

In the operation process, a draw hook is required to draw soft tissues such as meibomian, muscle and the like so as to obtain a larger visual field and operation space; the periosteal anterior tissue needs to be separated using a periosteal dissector to obtain the orbital fat filling space. However, the drag hook used clinically at present is a meibomian drag hook, and the drag hook has a small length, can only pull the meibomian, and can not pull soft tissues such as muscles below the meibomian, so that a good operation view and operation space can not be provided. After other right angle drag hooks such as thyroid drag hooks are used for replacement, the separation is difficult due to the limitation of the size of a conjunctival incision and the application of a periosteum stripper. Thus, the size and style of the existing surgical instruments are not suitable for conjunctival access orbital fat release lacrimal drainage procedures. Based on the clinical requirement, a novel conjunctival access orbit fat release lacrimal canal filling operation retractor is designed.
