Orthopedic implant inserter with removable jaws

摘要

An orthopedic implant inserter is provided with removable jaws. The jaws are connected to handles of the inserter by retainers. Each retainer includes a shaft and a latch. The shaft is configured to be received within mounting bores of a jaw and the associated handle. The latch is connected to the shaft and movable between a release configuration and a retaining configuration. In the release configuration, the shaft is removable from the mounting bores and the jaw is thereby removable from the associated handle. In the retaining configuration, the shaft is secured within the mounting bores and the jaw is thereby secured to the associated handle.

主权项

1. An orthopedic implant inserter comprising:
first and second facing handles joined for relative movement with respect to one another in a first plane, the first handle including a first opening extending through the first handle and the second handle including a second opening extending through the second handle; a first implant-engaging jaw removably mounted to the first handle; a second implant-engaging jaw removably mounted to the second handle, the first and second implant-engaging jaws are spaced apart from and independent of one another, and each implant-engaging jaw is removable from its associated handle independent of removal of the other implant-engaging jaw; and an adjuster configured to move the first and second handles away from and toward each other, the adjuster comprising: a shaft that passes through the second opening in the second handle and the first opening in the first handle, the second handle configured to advance along a length of the shaft toward or away from the first handle to move the first and second implant-engaging jaws toward or away from each other; and a knob configured to control the advancement of the second handle either toward or away from the first handle, the knob movable on a portion of the shaft extending beyond an external side of the second handle,wherein
each implant-engaging jaw comprises a base, an implant support, and a retainer that is movable between a retaining configuration in which the implant-engaging jaw is secured to the associated handle and a release configuration in which the implant-engaging jaw is removable from the associated handle, and each retainer includes:
a shaft for insertion into mounting bores on the base of each implant-engaging jaw and the associated handle, the shaft of the retainer extending through the base of the respective implant-engaging jaw in a generally parallel orientation to the implant support of the respective implant-engaging jaw, wherein the shaft of each retainer extends in a second plane perpendicular to the first plane when the retainer is in the retaining configuration; anda latch comprising:
a first leg for pivotally connecting to a first end of the shaft of the retainer via a pin;a second leg configured to removably engage a second end of the shaft of the retainer via an aperture;a resilient cross beam connecting the first leg and the second leg; anda biasing member extending from the resilient cross beam.
