Holder for implantation and extraction of prosthesis

摘要

Disclosed is an implant holder for an implant device comprising a locking mechanism that in a first position causes a clamp coupled to an implant device to lock such that the clamp cannot be decoupled from the implant device, and in a second position causes the clamp to unlock the implant device such that the clamp remains coupled to the implant device in the absence of a sufficient decoupling force but is decoupled from the implant device in the presence of a sufficient decoupling force. Also disclosed are methods of implanting an implant device using an implant holder by coupling the implant device to the implant holder, locking the implant device and the implant holder, emplacing the implant device utilizing the implant holder, unlocking the implant device and the implant holder such that the implant device is still coupled to the implant holder but can be decoupled with sufficient force.

主权项

1. An implant holder for an implant device, the implant holder comprising:
a clamp for coupling to and decoupling from the implant device, the clamp including:
a central body having an interface for coupling with the implant device; anda stem extending from a proximal end of the central body, a proximal end of the stem including a stem mating feature;the central body including a first arm and a second arm extending from the stem, the first arm and the second arm each including a central spacer portion having a thickness less than the thickness of each of the respective first and second arms, the central spacer portion sized and configured to abut at least one of an upper endplate and a lower endplate of the implant device, such that a longitudinal line of the upper endplate and the lower endplate of the implant device is maintained in a parallel configuration with respect to a longitudinal line of the clamp, the first arm and the second arm each including an exterior locking surface extending at an acute angle with respect to a longitudinal axis of the implant holder and a projection extending from and contained on the locking surface in a direction parallel to the longitudinal axis of the implant holder; and a locking mechanism including:
a hollow sleeve having an opening at a distal end of the hollow sleeve, the opening sized and configured to translationally and rotationally receive at least a portion of the stem;a clamp coupler attached to the distal end of the hollow sleeve, the clamp coupler including a pair of locking tines each defining a corresponding locking surface each sized and configured to mate with a corresponding one of the exterior locking surfaces of the central body, wherein said locking surfaces of the locking tines extend at an acute angle with respect to a longitudinal axis of the implant holder, the locking surfaces of the locking tines including recesses extending through the locking tines in a direction perpendicular to the longitudinal axis of the implant holder, the recesses sized and configured to mate with the corresponding projections extending from the exterior locking surfaces of the clamp; anda shaft translationally and rotationally received within the hollow sleeve along a central axis of the implant holder, a distal end of the shaft including a shaft mating feature sized and configured to mate with the stem mating feature; wherein the locking mechanism, in a first position, causes the central body to mate with the clamp coupler locking the clamp to the implant device such that the clamp cannot be decoupled from the implant device; and wherein the locking mechanism, in a second position, causes the central body to be located apart from the clamp coupler unlocking the clamp from the implant device such that the clamp remains coupled to the implant device in the absence of a sufficient decoupling force but the clamp is decoupled from the implant device with the application of the sufficient decoupling force.
