Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment processing, and in particular relates to a product cutting device. Background Art

[0002] Bone damage is a common problem in orthopedic treatment. When bone damage occurs, it is necessary to fill the defective bone tissue with bone repair materials. This not only facilitates the fixation of the damaged area, but also promotes the regrowth of bone tissue. The production of bone repair materials requires cutting raw bones such as cattle bones and pig bones into strips and granules before using them as fillers.

[0003] When using a strip cutting machine to cut the above-mentioned raw bones such as cattle bones and pig bones into strips and materials, it is necessary to start cutting from one end of the aggregate. During the cutting process, the aggregate is easy to slide to the other side, so the aggregate needs to be fixed during the cutting process. However, the structure of the existing strip cutting machine is relatively simple and does not have the function of clamping the aggregate. During the cutting process, the aggregate needs to be manually fixed, which is inconvenient and unsafe. In addition, after one end is cut, it needs to be pushed manually, which is also extremely unsafe for the operator and has poor safety. Utility Model Content
