BONE SCREW WITH 3D PRINTED THREAD LOCKING FEATURE

The invention provides a bone screw with a 3D printed thread locking feature. The bone screw assembly includes a first body, a second body, and a thread locking assembly that may couple the first bodywith the second body. The first body includes a proximal portion, a distal portion that may pierce bone in response to rotation of the first body about the longitudinal axis, and a first threaded section that may engage bone. The second body defines a through hole that may receive the distal portion of the first body. The thread locking assembly includes a first thread locking section associatedwith the proximal portion of the first body, and a second thread locking section associated with the through hole of the second body. Either the first threaded locking section or the second threaded locking section deforms the other in response to rotation of the first threaded locking section relative to the second threaded locking section. 本发明题为"具有3D打印的螺纹锁定特征的骨螺钉"。本发明提供了一种骨螺钉组件，其包括第一主体、第二主体以及可将第一主体与第二主体联接的螺纹锁定组件。第一主体包括近侧
