Description

Technical Field

[0002] In various biological experiments such as cell culture and sampling, it is often necessary to peel off the thin membrane on the surface of animal skin or organs. Since these membranes are thin and tightly attached, it is difficult to separate them, and it is difficult to achieve effective peeling without damaging the sample. Currently, there are circular cutting tools suitable for the food processing industry, but this method is relatively crude and cannot achieve accurate separation of biological samples, which requires the use of a membrane peeling device.

[0003] In the existing public technology, the utility model patent of Chinese patent publication number CN217250869U discloses a film scraping tool, which is arranged by bending the scraping blade body toward one side, and the bending angle of the scraping blade body is an obtuse angle greater than 120°; a blade is provided on the edge of the scraping blade body away from the output shaft, and the blade is a single-edged blade, which is arranged on the side of the scraping blade body facing the bend, and the blade side of the blade forms a cutting edge with the side of the scraping blade body facing away from the bend, and the blade of the scraping blade body can easily cut into the adhesive layer of the substrate, ensuring that the attachments on the surface of the substrate are peeled off and removed, avoiding the blade from exerting a large impact force on the substrate itself, and achieving the purpose of effectively removing the surface coating; however, the device still has the following defects:

[0004] When the above-mentioned membrane scraping tool contacts the thin film on the surface of the organ, the thin film on the surface of the organ is long and short. It is time-consuming and laborious to scrape the longer thin film on the surface of the organ with the blade, while the force area of ​​the hand is smaller for the shorter thin film on the surface of the organ. The sharp blade can easily damage the thin film on the surface of the organ when scraping it, and it is difficult to achieve adjustable peeling according to the size of the thin film on the surface of the organ. Therefore, a membrane peeling device suitable for multiple species is needed. Utility Model Content
