Spine treatment lateral approach access equipment

摘要

Minimally invasive surgery is a technique that provides spinal treatment from a lateral approach. Minimally invasive surgery uses one or more extended retractors that form an extended access route, such as a lateral access to the spine in a non-limiting example. Minimally invasive surgery uses an internal retractor that is reversibly expandable using a removable retractor insertion device that forms an extended access route. A concatenated jack extends a set of two or more extension retractors to form an extension access route.
