Claims20
A surgical instrument for implanting an implantable material to a pelvic region, the instrument comprising:
- a handle having a longitudinal axis and an elongate width dimension normal to the longitudinal axis, the elongate width dimension defining a midplane,
- a needle portion extending from the handle along the longitudinal axis, the needle portion comprising
- a spacer portion connected to the handle,
- a three-dimensional region connected to the spacer portion distal from the handle, and having structure in three dimensions, and
- a needle distal end at the distal end of the three-dimensional region,
- wherein the needle portion is sized and shaped to extend between an incision substantially adjacent to a patient's obturator foramen, through the obturator foramen, and to a medial incision;
- and
- wherein the needle distal end is located at an angle between 20 to 70 degrees from the midplane.
A surgical instrument for implanting an implantable material to treat incontinence, the instrument comprising:
- a handle,
- needle extending from the handle, the needle comprising
- a spacer portion connected to the handle, and
- a three-dimensional region connected to the spacer portion distal from the handle, and having structure in three dimensions including a needle distal end at the distal end of the curved portion,
- wherein
- the needle portion is sized and shaped to extend between an incision substantially adjacent to a patient's obturator foramen, through the obturator foramen, and to a perineal incision;
- the three-dimensional region has a length in the range from 2.3 to 5 inches and a diameter in the range from 2.3 to 5 inches, and
- an axis of the needle end portion lies within a plane that is orthogonal to the longitudinal axis of the tool.
A method of performing a surgical procedure, the procedure comprising a step of rotating a surgical instrument having a handle comprising a midplane, about a longitudinal axis, the method comprising
- providing a surgical instrument comprising a handle, a functional section that engages with tissue, a surgical implant, or a surgical instrument, the handle comprising an elongate dimension defining a midplane,
- engaging the functional section with one or more of tissue, a surgical implant, and a surgical instrument,
- grasping the handle with the midplane approximately parallel to the palm, and
- rotating the handle using the hand such that
- during the rotation the handle rotates at least ninety degrees, and
- during ninety degrees of the rotation the hand traverses ninety degrees between a forty-five degree open palm and a forty-five degree closed palm.
