Problems solved by technology

[0002] During surgery, the humeral head of type C fractures in the AO classification of comminuted shoulder joint fractures often occurs completely free and detached. The humeral head detaches and shifts, requiring accurate reduction and drilling to prepare for the establishment of intramedullary nail implantation. Generally, the fractured bone is butt-jointed and reset, and then a steel nail is placed. However, the difficulty of this kind of reduction operation is that it is difficult to establish the intramedullary nail implantation channel, which brings many difficulties to the recovery operation.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a humeral head reduction holding forceps. Background technique [0002] During surgery, the humeral head of type C fractures in the AO classification of comminuted shoulder joint fractures often occurs completely free and detached. The humeral head detaches and shifts, requiring accurate reduction and drilling to prepare for the establishment of intramedullary nail implantation. The channel is usually to butt the broken bone and reset it, and then put a steel nail on it. However, the difficulty of this kind of reduction operation is that it is difficult to establish the intramedullary nail implantation channel, which brings many difficulties to the recovery operation. Contents of the invention [0003] The object of the present invention is to provide a humeral head reduction and holding forceps to solve the above background technical problems. [0004] In order to a...
