Abstract
A kit of medical tools for removing screws from a patient in surgical procedures, including both the kit and the method of arranging the kit and its bits and tools. There are two removable trays in a container, one for the bits and one for the tools, and the trays stack upon the other in the container. Corresponding indicia are on both the bits and the supporting trays so the bits can be organized and readily selected by the surgeon, and an abutment aligns the bits in resilient grippers on the bit tray.
Claims13
A kit of medical tools for removing skeletal screws, comprising:
- a box including a base having a bottom and upwardly extending side walls defining an upwardly faced opening,
- a first tray and a second tray disposed in said box one above the other and extending fully between said side walls,
- lift portions on both said trays for lifting said trays from said base through said upwardly faced opening,
- a top removable disposed on said base for enclosing said base and covering said trays in said base,
- a plurality of screw removing bits,
- a plurality of bit grippers on said first tray having bit-receiving openings spaced apart on said first tray for releasably restraining said bits against some movement on said first tray,
- said bits being removably disposed in said bit-receiving openings for separated disposition and ready removal of said bits from said first tray and having portions thereon specially configured for being engaged for rotational driving said bits;
- a plurality of tools and with at least some of said tools having portions thereon matching, and thus being mateable with, said special configuration for rotational driving engagement of said bits, and
- a plurality of tool receptors on said second tray and having tool-receiving openings spaced apart on said second tray and with said plurality of tools separately disposed in said tool receptor openings for restraint against some movement and for separated disposition and ready removal from said second tray.
