Description
Technical field
The invention belongs to advanced material forming technique fields, and in particular to a kind of fixed bone of local regularity flexible forming metal
The method and bending forming tool of plate.
Background technique
In order to alleviate life stress, obtain mental support, the nursing scale of small-sized pet is gradually increased, is thus expedited the emergence of people
The continuous growth in Medical pet market.Fracture is symptom relatively conventional in Medical pet, and general therapeutic fracture needs to use
Treatment, bone plate is fixed in PRCL (Point-contact Reconstruction Compress Locking) locking bone plate
It is bonded after in-plane bending, bending and torsion with fracture injury bone, then pedicle screw, is allowed to be adjacent to bone.By
Injury bone surface is space curved surface, and type face is complicated, to need the bone plate of different complex profiles for different injury bones
It is fixed.Such bone plate needs to realize that in-plane bending, bending and torsion three classes become by manually adjusting in conventional manner
On the one hand shape manually adjusts to be bonded injury bone and is difficult to hold forming accuracy, bone plate cannot be bonded completely with bone, another
The deformation of aspect three classes needs at least two class tools (every class tool needs two tools to work at the same time) to be adjusted, and efficiency is lower.
The flexible formings such as single-point progressive molding, multi-point forming based on advanced Numeric Control Technology technology is orthopedic in ankle
(wherein bone plate used in ankle part orthotic device is applied in disposable, the personalized medical-therapeutic treatment of human body customization such as device, skull repairing
It is aperture web plate for bone plate used in non-porous tabula rasa, skull repairing), but be not yet used in pet fracture medical treatment, mainly due to pet
Bone plate used in fracture medical treatment is in fine strip shape, and approximate one-dimentional structure, mesh is larger (be used for pedicle screw), at present single-point it is progressive at
