Implant assembly having an angled head

摘要

An implant assembly includes an implant having an upper element and a lower element coaxially aligned with one another. The upper and lower elements are configured to be displaced relative to one another along a longitudinal axis of the implant. The implant assembly also includes a setting tool having a cassette and a tool body. The cassette has a housing, a gear held by the housing, and a drive shaft driving the gear. The cassette holds the implant such that the gear engages the implant to displace the upper and lower elements relative to one another. The tool body has an inner portion and an outer portion being angled relative to one another. The cassette is mounted to the inner portion. The tool body has an outer shaft and an inner shaft rotatable received in the outer shaft. The inner shaft includes a flexible joint at the intersection of the inner and outer portions. The inner shaft drives the drive shaft of the cassette.

1. An implant assembly comprising:
a tool body having an implant end and an outer end opposite the implant end, the implant end being configured to be positioned in a patient, the outer end being configured to be held by a user outside of the patient, the tool body having an inner portion at the implant end and an outer portion at the outer end with an angled section between the inner and outer portions, the angled section angling the inner and outer portions relative to one another, the tool body comprising an actuator separately manufactured from, and coupled to, the inner and outer portions of the tool body, the actuator being configured to vary the angular orientation of the inner portion with respect to the outer portion while the tool body is located within a patient; an inner shaft rotatably received in the tool body, the inner shaft having a flexible joint extending through the angled section between a drive end and a second end, the flexible joint being rotatable within the angled section, wherein the flexible joint comprises a plurality of hex adapters having hexagon shaped openings that receive a drive end of another hex adapter, the drive end having a plurality of flats that engage the flats of the corresponding hexagon shaped opening, the hex adapters being configured to be positioned at a plurality of angles within the corresponding opening of the adjacent hex adapter, the inner shaft comprising a driver extending through the outer portion of the tool body and being coupled to the drive end of the flexible joint, wherein the flexible joint is configured to transfer rotation of the driver to the second end of the flexible joint; and a handle coupled to the driver for rotating the driver within the tool body.
