Technical Field

The invention relates to bone plate corollary equipment, in particular to a bone plate processing device for a trauma operation.

Background

The bone fracture plate is a plate-shaped fracture internal fixing device with holes, is usually matched with bone screws or bone wires clinically, and has different shapes because different bone fracture plates are used at different parts.

The holes on the bone plate are lightening holes and screw holes. The bone fracture plate is arranged in a human body when in use, so that the grinding requirement on the bone fracture plate is higher, if the bone fracture plate is ground to be non-smooth, the bone fracture plate can be damaged with bones or muscle tissues in the human body, and part of metal particles can fall into the human body, so that the grinding requirement on each position of the bone fracture plate is strict.

For a bone fracture plate, the position where the bone fracture plate is difficult to polish is the hole formed in the bone fracture plate and the hole openings at two ends of the hole are located along the position, chinese patent CN112959194B discloses a "refinement treatment device for an orthopedic bone fracture plate", which is mainly used for polishing the circular hole in the bone fracture plate, the shapes of the holes in different bone fracture plates are not consistent, and the holes in some bone fracture plates are not circular holes, for example, as shown in fig. 1, the figure is a clavicle distal end anatomical bone fracture plate, the bone fracture plate 1 comprises a plate body, a waist-shaped lightening hole, namely a hole to be polished 2, is formed in the plate body, and for the non-circular lightening holes, the existing bone fracture plate treatment device cannot polish the lightening holes.
