Abstract
A load assist device for facilitating the loading of a suture cartridge onto a cartridge carrier of a surgical instrument is disclosed. The device has a cartridge casing and a suture cartridge loaded into an interior storage space of the cartridge casing. The suture cartridge contains a suture filament for tying a surgical knot. When a cartridge carrier of a surgical instrument is inserted into an aperture for receiving the cartridge within the cartridge casing, the carrier passes through a carrier channel inside the casing until it reaches the cartridge storage space for loading the suture cartridge onto the cartridge carrier. The loaded cartridge carrier may then be withdrawn from the cartridge storage space for withdrawal from the cartridge casing. The device helps the surgeon or the operating room assistant with loading a suture cartridge onto a surgical instrument for the eventual deployment of a knot during surgery, and avoids some of the pitfalls inherent in loading, unloading and reloading suture cartridges onto the surgical instruments during procedures where it is necessary or desirable to place several knots for fastening tissue.
