Manufacturing method of pad-pasting-type anatomic-design ulna olecranon bone fracture plate

Abstract

The invention discloses a manufacturing method of a pad-pasting-type anatomic-design ulna olecranon bone fracture plate. The method comprises the steps of S1, building a ulna olecranon three-dimensional data model; S2, conducting appearance design on the ulna olecranon bone fracture plate according to a bone surface of the ulna olecranon three-dimensional data model, forming a ulna olecranon bone fracture plate data model fitting with a bone surface of the ulna olecranon, and designing a hole tacking structure; S3, manufacturing the ulna olecranon bone fracture plate according to the ulna olecranon bone fracture plate data model; S4, conducting amendment on the manufactured ulna olecranon bone fracture plate. According to the manufacturing method of the pad-pasting-type anatomic-design ulna olecranon bone fracture plate, the appearance of the ulna olecranon bone fracture plate is designed in a fitting mode according to the bone surface of the ulna olecranon three-dimensional data model, accordingly it is ensured that the ulna olecranon bone fracture plate and the bone surface of the ulna olecranon are well fitted, further, the good clinical fixing effect can be achieved, the difficulty of clinical treatment is reduced, and the recovery after an operation is ensured.

Description

technical field [0001] The invention relates to the technical field of medical appliances, in particular to a method for making a film-adhered anatomical olecranon bone plate. Background technique [0002] Fractures of the olecranon are more common, mostly in adults. The subcutaneous protrusion behind the proximal end of the ulna is the olecranon, which forms a semilunar notch with the coronoid process of the anterior ulna. This notch just articulates with the trochlear of the humerus. The ulna-humeral joint only has flexion and extension activities, and the olecranon fracture is an intra-articular fracture involving the semilunar notch. [0003] The treatment of olecranon fractures requires open reduction and internal fixation. Among the internal fixation methods, the plate and nail system is one of the most commonly used internal fixation methods. [0004] The principle of internal fixation treatment is to make an incision at the fracture end, place a bone plate so that...

Problems solved by technology

[0009] The manufacturing method of this kind of olecranon bone plate reduces the cost of research and development and manufacturing, but the design of this type of product can only meet the fit of the main bony landmarks, and some fractures may have poor local fit, that is to say , in clinical practice, there will inevitably be a mismatch between the olecranon bone plate and the patient's bone, which will bring the following problems to clinical treatment: the operation is more difficult; the fracture fixation effect is not good, and even fractures may occur Failure of immobilization; poor functional recovery of affected limb; secondary injury of local soft tissue
