Problems solved by technology

However, in the development and application of human amniotic membrane, because the amniotic membrane is soft and thin, only 0.02-0.05mm, it is very difficult to shape and cut, which has become an urgent problem to be solved in the industrial production of amniotic membrane
At present, there is no mechanized production equipment for amniotic membrane cutting, and most of them are manual operations with low production efficiency.

Embodiment 1

[0027] Such as figure 1 , 2 As shown, the amniotic membrane cutting device of the present inventor is composed of a cutting machine body 1, a lower mold base 2, a pressing and returning device 3, a cutting knife 4, a transmission device 5, and an auxiliary device 6 consisting of six parts. The structure of cutting machine body 1 is as Figure 5 As shown, it is composed of a platen and a fixed frame. A lower mold base 2 is arranged on the platen, and a transmission device 5 is arranged on the fixed frame. Transmission device 5 structure such as image 3 As shown, it includes a pinion, a gear and a rack, and the pinion is provided with a shaft hole and a groove mouth. The pressing and unloading device 3 is composed of a pressing plate, an unloading plate and an elastic member, and its structure is as follows: Figure 10 shown. The pressing and returning device 3 is installed on the lower end of the gear shaft, above the lower mold base 2 . Cutting knife 4 is installed on ...

Embodiment 2

[0029] The cutting knife 4 of the present invention includes a knife cavity wall and a knife handle, and the knife cavity wall is a right-angled trapezoidal or rectangular or square cavity structure surrounded by a substrate made of stainless steel or the like.

Embodiment 3

[0031] Such as Figure 11 As shown, in the present invention, the rectangular or square cavity structure surrounded by the substrate is provided with a dividing knife to divide the cavity into two corresponding right-angled trapezoids. It can cut two right-angle trapezoid human amniotic membrane tissue blocks at the same time, which can not only improve the utilization rate of amniotic membrane, but also distinguish the front and back of amniotic membrane.

Abstract

The invention relates to a human amniotic membrane cutting device, and belongs to the technical field of medical apparatus and instruments. The human amniotic membrane cutting device is applicable tomechanically cutting human amniotic membranes and comprises six portions including a cutting machine body, a lower mold base, a material compressing and withdrawing device, a cutting knife, a transmission device and an auxiliary device. The human amniotic membrane cutting device has the advantages that the human amniotic membranes can be mechanically cut by the human amniotic membrane cutting device, the human amniotic membrane cutting device is suitable for producing human amniotic membranes in different shapes on a large scale, the cutting quality can be guaranteed, and the production efficiency can be improved; the human amniotic membranes with different specifications can be cut after the human amniotic membrane cutting device is additionally provided with corresponding knives; a foundation can be laid for developing and utilizing the human amniotic membranes.

Description

technical field [0001] The invention relates to a human amniotic membrane cutting device, which is suitable for mechanical cutting of human amniotic membrane, ensures the quality of amniotic membrane cutting, improves the production efficiency of amniotic membrane cutting, and belongs to the technical field of medical devices. Background technique [0002] Human amniotic membrane is a translucent double-layer film attached to the fetal surface of the placenta. It has a smooth surface, no blood vessels, nerves and lymph, and has certain elasticity. It contains collagen, laminin, integrin, basic fibroblast growth factor, Hepatocyte growth factor, vascular endothelial growth factor, transforming growth factor and other components have biological characteristics of anti-inflammatory, antibacterial, anti-adhesion and low immunogenicity, and are a kind of natural biological materials. However, in the development and application of human amniotic membrane, because the amniotic memb...
