Abstract
A surgical instrument comprises a first member extending between a first end including a first mating surface and a second end including an inner surface defining a passageway. A second member extends between a first end including a second mating surface and a second end including a first dimension and a second dimension greater than the first dimension. The second end of the second member includes an opening configured for movable disposal of a guidewire. The second member is disposable within the passageway such that the second ends are substantially uniformly tapered and the first dimension extends from the second dimension to space tissue. Systems and methods are disclosed.
Claims20
A percutaneous instrument comprising:
- a first member extending between a first end including a first mating surface and a second end, and including an inner surface defining a passageway;
- and
- a second member extending between a first end including a second mating surface and a second end including a first dimension and a second dimension greater than the first dimension, the second end of the second member including an opening configured for movable disposal of a guidewire,
- wherein the second member is disposable within the passageway such that the mating surfaces are engaged and the second ends are disposed in a substantially uniformly tapered configuration and the first dimension extends from the second dimension in an orientation to penetrate and space tissue.
A percutaneous instrument comprising:
- a first member extending between a first end having a first opening and a second end having a second opening, the first opening including a first mating surface, the first member having an inner surface defining a passageway in communication with the first and second openings;
- and
- a second member removably disposed within the passageway, the second member extending between a first end including a second mating surface and a second end extending through the second opening including a first dimension and a second dimension greater than the first dimension, the second end of the second member including an opening configured for movable disposal of a guidewire, wherein the passageway is configured for relatively movable disposal of at least one surgical component including a tap.
A surgical system comprising:
- a percutaneous instrument comprising:
- a first member extending between a first end including a first mating surface and a second end, and including an inner surface defining a first passageway, the first mating surface including a threaded portion of the inner surface, the second end having a decreasing taper that defines a first opening, the first member including an outer sleeve having an outer surface configured to space tissue, and
- a second member extending between a first end including a second mating surface and a second end including a first dimension and a second dimension greater than the first dimension, the second dimension having a decreasing taper that transitions to the first dimension, the second mating surface including a threaded portion of an outer surface of the second member, the first end of the second member further including a drive configured for engagement with a socket of a tool, the second end of the second member including an inner shaft including an inner surface defining a second passageway that communicates with an opening in the second member,
- wherein the second member is removably disposable within the first passageway such that the mating surfaces are engaged and the second ends are disposed in a substantially uniformly tapered configuration and the first dimension extends from the second dimension in an orientation to penetrate and space tissue;
- a surgical component including a tap configured for relatively movable disposal in the first passageway;
- and
- a guidewire configured for relatively movable disposal in the second passageway.
