[0017] Since the first stripping head and the second stripping head are respectively provided at both ends of the handle, and the uses of the first stripping head and the second stripping head are different, the surgeon can conveniently hold the handle and switch back and forth to operate the first stripping head and the second stripping head. At the same time, when different stripping heads need to be replaced, by rotating the first stripping head or the second stripping head, the anti-slip groove provided on the outer wall of one end can increase the friction with the surgeon's palm, thereby facilitating the rotation of the first stripping head or the second stripping head, and the first stripping head or the second stripping head can be disassembled by using the threaded connection between the fixed threaded rod and the threaded hole on one side of the threaded seat, thereby achieving the effect of facilitating the replacement of different stripping heads. The adjusted extension rod length can be directly used for operation, and there is no need to readjust the appropriate use length, which improves convenience. At the same time, it is also convenient to remove the stripping head for cleaning, which enhances the convenience of cleaning. Therefore, during the operation on the patient's nose, the surgeon does not need to constantly take and replace the entire stripper, thereby improving operating efficiency.

[0018] In the utility model, the periosteal stripper can facilitate the surgeon to hold the handle and switch back and forth between the first stripping head and the second stripping head through the replacement mechanism, and the first stripping head or the second stripping head can also be disassembled, so as to achieve the effect of facilitating the replacement of different stripping heads, thereby eliminating the need for the surgeon to constantly take and replace the entire stripper, thereby improving the operation efficiency;
