SURGICAL RATCHET TOOL, SYSTEM AND METHOD

摘要

A surgical ratchet tool and system along with associated methods are disclosed. The surgical ratchet tool can include a relatively simple encompassing member that included a pawl extending into the opening for directly contacting a nut during surgery. The ratchet tool and system can be used for various types of surgery in which easy sterilization and a reduced profile for a ratchet tool is desired. For example, the ratchet tool can be used during surgery for adjustment of a spinal implant, where manipulation of a nut located on a downtube connected to a screw and/or spinal rod is desired. The encompassing member and pawl can be constructed/molded as a single piece unitary structure. A first handle and possibly a second handle can extend from an outer periphery of the encompassing member.

主权项

1. A surgical ratchet, comprising:
an encompassing member having an inner peripheral surface, an outer peripheral surface opposed to the inner peripheral surface, and an opening; a first handle extending away from the outer peripheral surface of the encompassing member, the handle having a proximal end and a distal end opposite the proximal end with a longitudinal axis extending therebetween, the distal end of the first handle being connected to the outer peripheral surface of the encompassing member; and a pawl having a fixed end attached to the distal end of the first handle, the pawl extending away from the first handle and extending into the opening which is defined by the inner peripheral surface and the distal end of the first handle, the pawl having a biased portion and a head located at a free end opposite the fixed end, the biased portion of the pawl disposed between first and second opposing portions of the inner peripheral surface, wherein the head is movable with respect to at least one of the first handle and encompassing member.
