Problems solved by technology

The potential for pop-out can be reduced by adjusting the clamp to lock the jaws to a near-full grip, but this makes the adjustment uncomfortable for the user
[0007] Nevertheless, the jaws in these existing gripper designs either do not provide temporary locking or are limited to temporary locking of a single size of fixation element

Abstract

A clamping device for attaching to an external fixation element of an external fixation system includes first and second jaws each having inner and outer surfaces, with the inner surface of the first jaw and the inner surface of the second jaw together forming a passage configured to receive the external fixation element. A locking system is engageable with the first and the second jaws. A portion of the locking system is moveable relative to the first and the second jaws between a first position where the locking arrangement is configured to prevent release of the external fixation element having a first size from between the first jaw and the second jaw and a second position where the locking arrangement is configured to prevent release of the external fixation element having a second size from between the first jaw and the second jaw.

Description

technical field [0001] The present application relates to external fixation systems for stabilizing bone fragments. Background technique [0002] External fixation systems utilize bone pins or wires to stabilize bone fragments. These pins or wires are held in spatial position relative to each other by the fixing frame. The frame can be made of rings, columns, rods or other structural members. The simplest frames are usually made of rods (sometimes called rods). In order to hold the rods on each other and on the fixing element, typically a clamp is engaged to two or more elements. Clamps can also be used to hold rods to rings, pins to rings, posts to rings, and the like. [0003] Users typically construct external fixation systems by placing pins into the bone and assembling the framework to approximate the desired shape, then adjusting the position of the bone to place the bone fragments into their correct anatomical position. The frame is then locked in place by lockin...
