Preparation method of anterior chamber separation saccule

Abstract

The invention discloses a preparation method of an anterior chamber separation saccule. The preparation method includes the steps: taking a half-compliance and / or non-compliance high-molecular material to remove dust, and placing the material into an air dry oven to perform drying; (2) placing the dried material into an extruding machine to form a pipe; (3) stretching the extruded pipe in a stretcher to form a thin-wall pipe; (4) placing the stretched thin-wall pipe into a saccule mold to perform blow molding, blowing-up a parison to cling on the inner wall of the mold, performing cooling anddemolding to obtain the saccule, and arranging a catheter on the saccule; (5) folding the saccule prepared in the step (4) by taking the catheter as a axis through a saccule folding machine to obtainthe anterior chamber separation saccule. The saccule prepared by the method is high in strength, good in durability and of an oblate spheroid structure, the diameter of the saccule is 8-9mm, the plumped height of the saccule is about 1mm, sufficient space can be reserved for an operation when phacoemulsification cataract extraction is performed, and corneal endothelial cells can be effectively protected.

Description

technical field [0001] The invention relates to the technical field of medical operation assistance, in particular to a preparation method of an anterior chamber isolation balloon. Background technique [0002] The most widely used cataract surgery method in my country is phacoemulsification cataract extraction. The corneal endothelial cells will be damaged to varying degrees during phacoemulsification of the crystal nucleus, which will lead to a low cure rate of cataract and bring greater pain to the patient. In the past, doctors used air or balanced saline solution to maintain the anterior chamber surgical space, but their protective effect on the corneal endothelium was weak. [0003] At present, before performing phacoemulsification cataract extraction, it is necessary to know the condition of the patient's corneal endothelial cells. If the density of the corneal endothelium is low, the operation cannot be performed, so that the patient cannot receive timely and effecti...

Problems solved by technology

Phacoemulsification of the crystal nucleus will cause varying degrees of damage to the corneal endothelial cells, resulting in a low cure rate of cataract and greater pain to the patient

In the past, doctors used air or balanced salt solution to maintain the anterior chamber surgical space, but their protective effect on the corneal endothelium was weak

[0003] At present, before performing phacoemulsification cataract extraction, it is necessary to know the condition of the patient's corneal endothelial cells. If the corneal endothelial density is low, the operation cannot be performed, so that the patient cannot receive timely and effective treatment

Later, viscoelastic agent became an ideal adjuvant in phacoemulsification. Although viscoelastic agent is an ideal adjuvant in phacoemulsification cataract extraction, it also brings many adverse reactions to the patient's cornea and its adjacent tissues.

For example, due to unclean cleaning, its own composition and molecular structure, etc. during use, the corneal endothelium will be insufficiently protected and the cornea will be damaged.
