Technical Field

[0001] The utility model belongs to the technical field of medical instruments, and in particular relates to a periosteal stripper. Background Art

[0002] The periosteum is a solid connective tissue capsule that covers the bone surface except for the joints. It is very densely attached to the bone at the bone ends and tendon attachment sites. In orthopedic surgery, it is usually necessary to peel off the periosteum.

[0003] The periosteal stripper used in orthopedic surgery mainly consists of a handle and a stripping knife, and is mainly used to strip the periosteum on both sides of the fracture site. This periosteal stripper has a single function and cannot easily install bone screws after stripping the periosteum. The surgical operator needs to find a screwdriver to complete the operation, which has low operating efficiency.

[0004] The utility model patent with announcement number CN201806759U in the prior art discloses a "multifunctional periosteal stripper", which includes a handle and a stripping arm, and is characterized in that a bone file is provided on the handle, and a screwdriver is provided at the front of the bone file. It has the technical effect of being able to strip the periosteum, file the bone flat, and install bone screws, thus reducing the difficulty of work for medical staff.

[0005] However, the above-mentioned "multifunctional periosteal stripper" still has shortcomings in actual use: the screwdriver and the stripping head cannot be separated, so that in operations that do not require the installation of bone screws, the extra screwdriver will generate extra weight and occupy extra space, increasing the operating burden of the surgical operator and affecting the surgical effect.

[0006] Based on this, a periosteal stripper is considered to be designed. Utility Model Content
