Description

Technical Field

[0001] The utility model relates to the technical field of medical appliances, in particular to a reduction and fixing forceps. Background Art

[0002] For the treatment of oblique fractures, the fracture fixation needs to be overlapped with the original state and then fixed. However, oblique fractures usually involve longer bone segments, which require a long opening for treatment. The surgical operation is complicated and causes greater harm to the patient.

[0003] The published patent document with publication number CN221450732U discloses a fracture reduction forceps, including a fixed rod, a movable rod, a screw hole, a nut platform, a screw, a nut, a variable baffle, a universal joint and a housing, wherein the fixed rod is arranged below the movable rod.

[0004] However, the above-mentioned prior art still has some shortcomings when used. The above-mentioned prior art is to manually rotate the nut to make the No. 1 bone clamping arm and the No. 2 bone clamping arm move toward each other, thereby reducing and fixing the fractured bone. It is not convenient to quickly reduce and fix the fractured bone. For this reason, we propose a reduction and fixation pliers. Utility Model Content
