Abstract
An implant inserter for use in ALIF spine surgery, wherein the inserter has a flexible bracket, biased closed, onto which two long blades can be removably attached.
Claims36
A vertebral body implant inserter, comprising:
- a) a elongated central body having a distal end, a proximal end, an outer surface, a longitudinal throughbore therethrough, and a pair of spring members extending from the outer surface,
- b) a pair of blades having a distal end portion and a base portion, the base portion of each blade detachably coupled to at least one of said spring members,
- c) a shaft advancable within the throughbore, the shaft having an outer surface having a threadform thereon.
A vertebral body implant inserter, comprising:
- a) a elongated central body having a distal end, a proximal end, an outer surface, a first longitudinal throughbore therethrough,
- b) a bracket having i) an intermediate portion having a second longitudinal throughbore therethrough, ii) a first endportion, and iii) a second endportion, each endportion forming a spring member, the intermediate portion contacting the distal end of the central body so that the first longitudinal throughbore aligns with the second longitudinal throughbore,
- c) a pair of blades having a distal end portion and a base portion, the base portion of each blade detachably coupled to a respective spring member,
- d) a shaft slidable within the first longitudinal throughbore, the shaft having an outer surface having a threadform thereon.
