Publication number: 20160214242Abstract: A latch and catch arrangement is disclosed, whereby a sleeve supporting a flexible hinge with an extended finger is oriented over a fluid connection to a socket guide. An alignment via a latch and catch between the sleeve and tool collar orients a flexible hinge, which may be of reduced thickness, over a bearing in a guide. The finger moves upward when a tool is inserted into a tool socket, and the flexible hinge, properly oriented by the alignment catch/latch, keeps the finger in the tool socket while allowing necessary movement to insert and remove a tool.Type: ApplicationFiled: April 1, 2016Publication date: July 28, 2016Applicant: ECA Medical InstrucmentsInventors: David Ivinson, David Tory
