Title: Spinal rod characterized by a time-varying stiffness
Inventor: NYGREN LEA A
IPC: A61B17/84
Filed: 2007-03-01
Abstract: A spinal rod (1 0) characterized by a time-varying stiffness. The rod comprises a first member (22,28,34,48,52,66,74,84,86,92,94) and at least one second member (24,26,35,40,44,50,54,60,68,72,76,82,90) that is mechanically coupled to the first member through a time-varying interface (30,36,38,56,58,59,80). The interface features a binding mechanism that degrades after surgical installation. For instance, the interface may be bioabsorbable and dissolve upon exposure to bodily fluids. In another instance, the second member may be comprised of a bioabsorbable material. In another embodiment, the interface may fail under cyclic loadig. In another embodiment, degradation of the bioabsorbable material may be inhibited through the application of a current source. The second member may be disposed within the first member. Alternatively, the first member and the second member may be disposed aside one another. The first member and the second member may be substantially similar in shape. One or more bioabsorbable plugs (62,66) may be used to at least temporarily seal the second member from bodily fluids once the spinal rod is installed. ® KIPO & WIPO 2009

Abstract: 본 발명은 기존의 용접 작업시 용접사가 부득이 양손을 사용하게 될 때 불편함과 위험을 무릅쓰고 용접면을 벗은체 한손으로는 용접할 물체를 잡고 또 다른 한손으로는 용접봉(속칭 고데)을 잡고 감각에 의한 눈감기를 하면서 위험한 용접을 해왔었는데, 
     이때 용접봉 끝의 스파크와 눈감기의 타이밍이 잘못 맞으면(현장용어-아다리) 눈에 심각한 손상을 입고 며칠씩 병원 신세를 지면서 고생을 하는 경우가 많았었다. 
     이에 본 발명은 이러한 문제점들을 근본적으로 해결하기 위하여 새로운 용접면을 개발하게 되었는데, 
     이 용접면은 용접 현장에서 용접사가 양손을 자유자재로 쓰면서도 확실하게 얼굴과 눈을 보호 할 수 있는 특성을 가지고 있는 저가의 용접면 이다. 
     물론 광센서를 이용한 국산 또는 외국제의 자동 용접면이 있기는 하지만 이 경우 가격이 2∼30만원대 이상의 고가이고 복잡한 작업 현장의 여건상 고가의 용접면이 자주 망가저서 수명이 짧아 대다수의 현장에서는 여전히 재래식 저가의 용접면을 사용하고 있는 것이 오늘날의 용접현장의 실태인 것이다. 
     따라서 본 발명은 이러한 문제점을 개선하여 확실하고 편리한 용접면을 부담 없는 저가로, 현장에 보다 많이 공급하여 용접사들이 보다 안전하고 유용하게 사용할수 있도록 하는데 그 목적이 있는 것이다. 
     또한 이 용접면의 간단한 사용법과 원리를 요약하면 다음과 같다. 
     본 용접면의 외형적인 모양은 일반 용접면과 같으나, 
     구조적인 면에서는 크게 개폐 흑경부분(도 1의1 창부분)과 용접면 하단의 턱걸이 부분(도 2의 11)으로 나누어 설명할수 있는데, 
     개폐 흑경부분은 용접면 내부의 피아노선(12)으로서 하단의 턱걸이와 연결되어 있어서 용접사 턱의 동작을 전달받아 열리고 닫히는 구조로 되어있으며, 
     용접면 하단의 턱걸이 부분은 용접사의 턱의 높 낮이를 조절할수 있는 턱걸이 KIT(도 2의11)와 이 KIT에 의지하고 있는 턱걸이(4) 구조로 되어 있는데, 
     용접사는 이 턱걸이에 자신의 턱을 맞추어 본 다음 용접면을 쓰고서, 
     턱을 벌리면 용접면의 흑경이(도 1의1) 열리고 턱을 닫으면 용접면의 흑경이 조임 스프링(도 9의 3)에 의해 닫히는 것을 특징으로 한 아주 간단하면서도 편리한 새로운 개념의 용접면인 것이다.
