Embodiment 1

[0029] Static adsorption / elimination method: Lay the electrostatic adsorption cast sheet of the device horizontally to the dry SIS surface, activate the static electricity generation switch, and adjust the output voltage to 7kV to adsorb the SIS film. With the end surface of the adsorbed SIS membrane facing up, punch the SIS membrane to a diameter using a ceramic stamping knife Specification products (such as Figure 4 ). Start the static elimination function of the device to carry out the bagging operation.

[0030] The above operation was repeated continuously 50 times, and the operation time and product yield of each operation were recorded.

[0031] Routine operation: Place the dry SIS film horizontally on the stainless steel operating table, use a stamping knife to stamp the SIS film into a diameter Specification products, and then carry out bagging operation.

[0032] The above operation was repeated continuously 50 times, and the operation time and product yield o...

Embodiment 2

[0035] Static adsorption / elimination method: Lay the electrostatic adsorption cast piece of the device horizontally on the surface of the dry acellular dermal matrix, start the static electricity generation switch, and adjust the output voltage to 6kV to adsorb the acellular dermal matrix. With the end surface of the adsorbed acellular dermal matrix facing up, the acellular dermal matrix was punched into a product with a size of 3 cm×3 cm using a ceramic punching knife.

[0036] Move the adsorption end that has absorbed the dry acellular dermal matrix to the upper end of the packaging material, adjust the relative position and start the static elimination of the device, and the acellular dermal matrix will automatically fall off into the packaging material for bagging operation.

[0037] The above operation was repeated continuously 30 times, and the operation time and product yield of each operation were recorded.

[0038] Routine operation: place the dried acellular dermal m...

Embodiment 3

[0042] Static adsorption / elimination method: Lay the electrostatic adsorption cast piece of the device horizontally to the surface of the dry pericardium, activate the static electricity generation switch, and adjust the output voltage to 8kV to adsorb the pericardium. With the end surface of the adsorbed pericardium facing upward, the pericardium was punched into a product with a size of 1 cm×1 cm using a ceramic porous punching knife. Eliminate static electricity and carry out bagging operation.

[0043] The above operation was repeated 40 times continuously, and the operation time and product yield of each time were recorded.

[0044] Routine operation: Place the dried pericardium horizontally on the stainless steel operating table, punch the pericardium into a size of 1cm×1cm with a porous punching knife, and then carry out the bagging operation.

[0045] The above operation was repeated 40 times continuously, and the operation time and product yield of each time were rec...

Abstract

The invention provides a natural biofilm material moving method which comprises the following steps: a, starting an electrostatic generator, so that a natural biofilm material can be adsorbed to an adsorption end surface; and b, after moving the natural biofilm material to a target position, starting the electrostatic elimination operation, so that the natural biofilm material can be divorced fromthe adsorption end surface and can reach the target position accurately. By adoption of the natural biofilm material moving method provided by the invention, the scale production operation steps canbe simplified during the production process, the operation slowness caused by electrostatic adsorption and the material damage caused by improper operation can be avoided, the production efficiency and the finished product ratio can be improved, and the cost can be reduced; and during the clinic use process, a wound surface of a patient can be quickly and accurately covered and repaired, the secondary operation caused by material edge warping and material overlapping can be avoided, the operation efficiency can be improved, the pain of the patient can be relieved, and the treatment effect canbe improved.

Description

technical field [0001] The invention relates to a method for moving natural biological film materials. Background technique [0002] Biomaterials play a key role in the construction of tissue engineering scaffolds and the process of promoting tissue regeneration, such as: strengthening the structural strength of the defect site; preventing the surrounding tissue from growing in; serving as a scaffold for seeded cells to proliferate in vivo; serving as cells, growth factors and genes carrier, etc. [0003] Natural biological materials have unique biological characteristics due to their origin, and natural biofilm materials are one of them, which have good application prospects. Due to the common characteristics of light weight and thin thickness of film materials from natural sources, they are prone to adsorption with production and surgical instruments due to static electricity during production and clinical use, or the floating of materials due to air flow, resulting in "t...
