Plate holder for manipulating bone plate

摘要

A plate holder is provided to facilitate percutaneous introduction of a bone plate, positioning of the plate on a bone surface, and stabilizing the plate while a fastener is inserted through the plate into the bone. The plate holder includes a proximal handle, a distal mount, and an arm extending between the handle and the mount. The mount includes a first portion which seats within a slot on the shaft of a plate, and a second portion at which the shaft is coupled and which includes a tapered proximal side. A set screw hole is provided through the first and second portions, and a set screw is provided therein. When the first portion is seated in a compression slot of a plate and the set screw is driven to seat, the set screw locks the mount to the plate.

主权项

1. A plate holder for manipulating a bone plate having an upper surface, a lower surface, and an elongate compression slot extending between the upper and lower surfaces in which a screw is intended to be received, comprising:
a) a handle; b) a shaft-like arm extending from the handle, the arm having a first end coupled to the handle and a second end; c) a mount coupled at the second end of the arm at a first location, the mount including a locking portion extendable into the compression slot and having a lip at a lower end thereof, a set screw hole laterally offset relative to the first location, the set screw hole having an entry for receiving a set screw on a same side as the lip and threads for engagement with a set screw; and d) the set screw threadedly engaged in the set screw hole, the set screw having a head at which the set screw is rotated within the set screw hole with a driver,
wherein when the locking portion is inserted into the compression slot and the set screw is advanced into the set screw hole, advancement of the set screw forces the lip into engagement relative to the bone plate to lock the plate holder relative to the bone plate so that the plate holder can be used to manipulate the bone plate.
