Description

Biomembrane auxiliary cutting tool

Technical Field

The application relates to the field of production and processing of biological membranes, in particular to a tool for auxiliary cutting of a bioactive material.

Background

For bioactive materials, especially materials which are easy to denature under the action of heat, such as acellular membranes, collagen membranes, gelatin membranes and the like, manual cutting is usually adopted, and a cutting knife and a steel ruler are used for cutting a large-size biofilm into small-size diaphragms. When manual cutting is used, the conventional cutting steel ruler can only ensure that the cutting is straight, and the unparallel of opposite sides can be caused in the cutting process, so that the shape and the size specification of a cut product do not meet the requirements, the product needs to be reworked or the product is directly scrapped, and particularly, when the size of the cut product is larger, the size error is more obvious; in addition, when the common steel ruler is used for cutting, the positions of the membrane to be cut and the steel ruler need to be moved and adjusted for many times, and the cutting speed is greatly influenced. When the large-size biological membrane needs to be reduced to a product with a smaller size, the adjustment times are more, taking 100 mm-100 mm membrane as an example, when the membrane needs to be cut into 50 mm-size membrane, the membrane needs to be adjusted and cut for 3 times, and when the membrane needs to be cut into 10 mm-size membrane, the membrane needs to be adjusted and cut for 99 times.

Therefore, when the biological membrane is cut, an auxiliary tool which can move the position of the membrane or the position of the steel ruler as little as possible and can quickly and accurately complete membrane segmentation is needed.

Through the scheme, when the film to be cut is irregular, the base line can be found at the upper side, and the cutting of the expected specification and size can be carried out under the base line.

Preferably, the longitudinal datum line of the cutting plate is 3-15 mm away from the left edge of the cutting plate.

By the scheme, the base line of the film to be cut on the left side can be realized, and the cutting of the expected specification size can be performed under the base line.

Preferably, the longitudinal datum line of the cutting board is a discontinuous hollowed-out dotted line when the transverse cutting seams intersect.

Through the scheme, after the longitudinal hollow lines and the transverse hollow lines are crossed, the crossed part is communicated and suspended.

Preferably, the right side of the cutting board is marked with a scale.

Through above-mentioned scheme, the cutting personnel can be according to waiting to cut the size, and convenient location is quick.

Preferably, the cutting plate has a thickness of 1-3mm, can be made of metal or polymer, and can be sterilized.

Through the scheme, the membrane to be cut can be ensured not to be polluted by microorganisms when being cut.

During cutting, according to the appearance and specification of the biological membrane, a cutting blade is used for cutting along the left side edge or the longitudinal datum line, and then cutting is carried out along the top or the transverse hollowed-out cutting seam; then cutting along the transverse hollowed-out cutting seams in sequence according to the required size; and finally, turning the bottom plate or the cutting plate by 90 degrees, aligning the original left side of the cut biological membrane with the top edge or the first cutting seam at the top of the cutting plate, and sequentially cutting along the transverse hollowed cutting seam according to the required size, so that the biological membrane with regular shape and size meeting the requirement can be quickly obtained.

The utility model has the beneficial effects that:

1) use this auxiliary fixtures to cut, can cut the diaphragm through size and the accurate cutting joints in position, guarantee opposite side is parallel, and adjacent limit is perpendicular, makes the diaphragm outward appearance regular, reduces by a wide margin because the diaphragm opposite side nonparallel that adjustment diaphragm or steel rule position arouse, the non-right angled condition in diaphragm four corners.

2) When the tool is used, the position of the primary bottom plate or the cutting plate is only required to be adjusted during cutting, the cutting of the whole membrane can be completed, when a large-specification biomembrane is cut into small-specification membranes, the size of the membrane to be cut is smaller, the cutting times are less than the cutting times, and the work efficiency can be greatly improved. Still take 100mm by 100mm diaphragm as an example, when needing to cut into 50mm by 50mm diaphragm, use this frock, need to adjust and cut 2 times, only reduce 1 time to adjust and cut the number of times than the steel ruler cutting; but when the diaphragm needs to be cut into 10mm by 10mm size, the diaphragm only needs to be adjusted and cut for 18 times at least, and the adjustment and cutting times are reduced by 81 times compared with the use of a straight steel ruler.
