Description

Technical Field

[0001] The utility model relates to the technical field of bone plates, in particular to a bone plate with adjustable radian. Background Technique

[0002] A bone plate is a plate-shaped fracture internal fixation device with holes, which is often used in combination with bone screws or bone wires clinically. It is divided into two categories: ordinary bone plates and compression bone plates, and can be made into strip-shaped, Y-shaped, L-shaped, T-shaped, etc. according to different uses.

[0003] When manufacturing a bone plate, the radian parameters of the bone plate are usually designed according to the growth and bending direction of the human skeleton, and bone plates of various sizes and models are designed. However, in actual clinical practice, doctors can only select the bone plate with the most suitable model according to the patient's bone parameters. The bending radian of different patients' bones is not the same. Even the most suitable bone plate cannot completely fit the patient's bone surface during use. In some clinical cases, doctors may temporarily perform additional minor bending operations on the bone plate to make the bone plate fit closely to the bone surface, which is convenient for locking and fastening with screws. However, the bending operation is relatively cumbersome and affects the surgical efficiency. Content of the Utility Model
