Dye.
The utility model patent, bone nail rivet nut screw thread nail head are arranged with tangent grooving, and thread rod part uses traditional method of indicating the pronunciation of a Chinese character grooving
Design principle.When carrying out fracture operation, when being screwed into screw, using the tangent grooving for being located at screw head, bone is carried out positive
Cutting is played the role of increasing self tapping ability, similar to the design principle of 202191437 U of patent U.After union, need
When taking out bone nail, using 1-3 traditional method of indicating the pronunciation of a Chinese character grooving for being located at rivet nut rear portion, when opposite direction back-outs bone nail, traditional method of indicating the pronunciation of a Chinese character grooving can
The newly-generated skeletal tissue of screw thread is adhered to effective excision excision, the cutting face of traditional method of indicating the pronunciation of a Chinese character grooving is perpendicular to bone nail axis, instead
The cutting edge of slot and bone nail axis are discharged into thread pitch at the angle of 5-20 degree convenient for cutting swarf earnestly, reach and quickly back-out bone
The effect of nail.Bone nail cap head uses quincunx design, increases the uniform contact area of screw cap head and screw driver, improves because of one
Word slot, cross recess or interior hex slot contact surface are small, discontinuity, bring bone nail cap head slipping phenomenon.
