Abstract
A surgical retractor comprises a support comprising a first mating part comprising a shaft, which defines a longitudinal axis, extending therefrom. At least one tissue engaging member extends between a first end defining a first axis and a second end defining a second axis and having a tissue engaging surface disposed along the second axis. The first end comprises a second mating part comprising a wall that defines an elongated cavity disposed along the first axis and being configured to receive the shaft such that the first axis and the longitudinal axis are co-axial. The wall is engageable with the shaft to align the second mating part with the first mating part such that the second axis intersects the longitudinal axis. Methods of use are disclosed.
Claims20
A surgical retractor comprising:
- a support comprising a first mating part comprising a shaft, defining a longitudinal axis, extending therefrom;
- and
- at least one tissue engaging member extending between a first end defining a first axis and a second end defining a second axis and having a tissue engaging surface disposed along the second axis, the first end comprising a second mating part comprising a wall that defines an elongated cavity disposed along the first axis and being configured to receive the shaft such that the first axis and the longitudinal axis are co-axial, the wall being engageable with the shaft to align the second mating part with the first mating part such that the second axis intersects the longitudinal axis.
A surgical retractor comprising:
- a frame comprising a first mating shaft extending therefrom along a first longitudinal axis and a second mating shaft extending therefrom, being spaced apart from the first mating shaft, along a second longitudinal axis, the first mating shaft including an outer surface having a spline configuration and the second mating shaft including an outer surface having a spline configuration;
- a first retractor blade extending from a first end defining a first axis to a second end defining a second axis, the first end comprising a wall defining a tubular cavity disposed along the first axis and being configured to receive the first mating shaft, the wall comprising an inner surface defining a spline configuration that mates with the spline configuration of the first mating shaft along the longitudinal axis of the first mating shaft to align and mount the first retractor blade with the first mounting shaft to support the second end of the first retractor blade adjacent tissue such that the second axis intersects the longitudinal axis of the first mating shaft;
- and
- a second retractor blade extending from a first end to a second end, the first end of the second retractor blade comprising a wall defining a tubular cavity configured to receive the second mating shaft, the wall of the second retractor blade comprising an inner surface defining a spline configuration that mates with the spline configuration of the second mating shaft along the longitudinal axis of the second mating shaft to align the second retractor blade with the second mating shaft to support the second end of the second retractor blade adjacent tissue.
A method of treating a spine, the method comprising the steps of:
- providing a support comprising a first mating part comprising a shaft, defining a longitudinal axis, extending therefrom;
- providing at least one tissue engaging member extending between a first end defining a first axis and a second end defining a second axis and having a tissue engaging surface disposed along the second axis, the first end comprising a second mating part comprising a wall that defines an elongated cavity disposed along the first axis;
- aligning the elongated cavity adjacent the shaft such that the second axis intersects the longitudinal axis and the tissue engaging surface is orientated for engagement with tissue;
- and
- engaging the shaft with the wall in relative rotational alignment to mount the at least one tissue engaging member with the support.
