Problems solved by technology

However, when the thickness of the bracket is reduced, the fatigue life of the bracket will be greatly reduced; in order to increase the fatigue life of the bracket, the thickness of the bracket must be increased, resulting in a contradiction between the fatigue performance and the structural size of the bracket

Abstract

The invention discloses a method for processing a lightweight orthopedic stent. The method comprises the steps that the orthopedic stent is tested according to a structural parameter of the orthopedicstent and a load spectrum of a stent service interval to determine a fatigue life before strengthening of the orthopedic stent; mechanical analysis is performed on the orthopedic stent to determine afailure zone so as to perform laser peening treatment on the failure zone of a sample stent; the fatigue life of the sample stent after strengthening is tested and a preferred thickness is determinedaccording to the fatigue life before strengthening and the fatigue life after strengthening; a processing instruction is generated according to the preferred thickness so as to process the orthopedicstent with the preferred thickness as a processing thickness and perform laser peening treatment on the failure zone to obtain the lightweight orthopedic stent. The method can further reduce overalldimensions of the orthopedic stent without reducing the fatigue life of the orthopedic stent.

Description

technical field [0001] The invention relates to the field of laser shock strengthening, in particular to a processing method of a lightweight orthopedic bracket. Background technique [0002] At present, the trend of economic globalization and population aging is intensifying. With the rapid development of transportation, fractures caused by accidental accidents are the most common patients in orthopaedics. In clinical treatment, orthopaedic stents with better stiffness and strength are used to fix fracture sites. Fixation can provide a stable mechanical environment for the fractured tissue in the short term after surgery and prevent re-injury. And provide solid support for the body, which is beneficial for patients to carry out normal activities during the rehabilitation process. [0003] Studies have shown that the elastic modulus of human bones is 10-40GPa, and that of titanium alloys is 110GPa. Since the stiffness of the scaffold is about 2 to 10 times that of the bone...
