Abstract
A surgical instrument to implant spinal implants including a shaft, a sleeve, and a handle assembly. The shaft defining a longitudinal axis and having a slotted portion with first slots and second slots. The sleeve rotatably disposed around the slotted portion. The handle assembly pivotably attached to the sleeve by a pivot pin, the handle assembly having a positioning tip sized to be received in the first and second slots of the slotted portion. The handle assembly can pivot about the pivot pin between a first position and a second position. In the first position, the positioning tip engages one of the first slots, while in the second position, the positioning tip engages one of the second slots.
Claims20
A surgical instrument to implant spinal implants, comprising:
- a shaft defining a longitudinal axis and having a slotted portion that defines a first set of slots and a second set of slots;
- a sleeve rotatably disposed around the slotted portion;
- and
- a handle assembly pivotably attached to the sleeve, the handle assembly having a positioning tip sized to be received by each slot of the first and the second set of slots,
- wherein the handle assembly can pivot about a pivot point between a first position and a second position,
- wherein in the first position, the positioning tip is oriented to engage a slot of the first set of slots, and wherein in the second position, the positioning tip is oriented to engage a slot of the second set of slots.
A surgical instrument for inserting implants, comprising:
- a body portion defining a longitudinal axis, the body portion having a first slot and a second slot;
- a handle assembly having a handle and a positioning tip that is configured to be retracted partially into the handle;
- and
- a sleeve portion disposed around the body portion, the sleeve portion having an extension portion that extends away from the body portion,
- wherein the handle is pivotably attached to the sleeve portion such that the handle can pivot between a first position and a second position, the handle being orthogonal to the longitudinal axis in the first position and oblique to the longitudinal axis in the second position, and
- wherein the positioning tip of the handle is disposed in the first slot in a first segment of the body portion when the handle is in the first position and disposed in the second slot in a second segment of the body portion when the handle is in the second position.
A surgical instrument for inserting implants, comprising:
- a body portion defining a longitudinal axis, the body portion having slotted portion that defines a first slot and a second slot that are spaced apart from each other along the longitudinal axis of the body portion;
- a handle assembly having a handle and a positioning tip that is slidably attached to the handle, the positioning tip is partially disposed within the handle;
- and
- a sleeve portion disposed around the slotted portion of the body portion and configured to rotate around the body portion when the positioning tip is retracted into the handle, the sleeve portion having an extension portion that extends away from the body portion,
- wherein the handle is pivotably attached to the sleeve portion such that the handle can pivot between a first position and a second position, the handle being orthogonal to the longitudinal axis in the first position and oblique to the longitudinal axis in the second position, and
- wherein the positioning tip of the handle is disposed in the first slot in a first segment of the body portion when the handle is in the first position and disposed in the second slot in a second segment of the body portion when the handle is in the second position, the second segment defining a larger diameter than that of the first segment.
