AI Technical Summary
Existing medical roll thermal film printers may cause the roll of thermal film to become stuck in the cutting tool due to its own curling after printing, making it impossible to cut properly and posing a risk of finger cuts.
A serrated film cutter was designed, which combines a pressure spring and a fixed slider to cut the film through the serrated blade. The film can be removed by manually breaking it at the break point, thus avoiding film blockage.
This effectively prevents film clogging, ensuring smooth printing the next time, while also reducing the risk of finger cuts.

[0003] The operation of the existing medical reel heat-sensitive film printer is usually to locally heat the film stretched out by the printing mechanism inside the printer on the reel heat-sensitive film roll, and after being heated to a certain temperature, the heat-sensitive film will have the pattern to be printed at the corresponding position. After printing, it is pulled out from the outlet end of the printer shell, and cut with scissors or other tools.
[0004] In order to facilitate cutting of the film, the existing medical reel heat-sensitive film printer usually installs the cutting tool behind the printing mechanism. Although this cutting method can ensure that the film is not affected by the external environment and that the finished film can be normally taken out, after cutting, because the reel heat-sensitive film roll is in a reel structure, it may be jammed in the cutting tool due to its own bending for a long time, causing the film to be jammed in the cutting tool during the next printing. If the operator wants to pull it out, it is likely to be cut by the cutting tool. TECHNICAL CONTENT
