Abstract
Described are surgical instruments for use in surgical procedures, related methods, systems, and kits, the instruments including features that optionally include one or more specific dimensions, and features that may result in an ergonomic advantage during use.
Claims23
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 when viewed along the longitudinal axis;
- an angle between an axis of the needle end portion and the midplane, the angle being an acute angle defined by the needle tip, an intersection of the axis and midplane, and the longitudinal axis when viewed along the longitudinal axis, is in the range from 30 degrees to 60 degrees:
- an angle between the axis of the needle end portion, and a circle having an origin at the longitudinal axis and a radius defined by the needle distal end, when viewed along the longitudinal axis, is less than 15 degrees;
- and
- the three-dimensional region has a diameter in the range from 1.25 to 5 inches.
The instrument of claim 10, wherein the three-dimensional region defines a curved portion comprising a needle end portion, and an axis of the needle end portion lies in a plane orthogonal to the longitudinal axis of the tool.
The instrument of to claim 10, wherein the three-dimensional region comprises a portion shaped like a spiral, helix, or partial helix.
The instrument of claim 10, comprising a needle end portion at the terminal inch of the three-dimensional region that comprises a curve.
(canceled)
The instrument of claim 10, designed for use in a male transobturator sling installation procedure, 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 2.2 to 4 inches and a diameter in the range from 2.3 to 5 inches, and
- the three-dimensional region defines a helix that includes an axis of a needle end portion within a plane orthogonal to the longitudinal axis of the tool.
The instrument of claim 10 designed for use in a male transobturator sling installation procedure, by dissecting a transobturator tissue using an outside-in dissection technique.
The instrument of claim 10 in combination with a surgical implant for treating incontinence,
- wherein the implant comprises a central support portion and two elongate end portions, and
- wherein the needle end portion is adapted to be associated with an end portion of the implant.
A surgical instrument for implanting an implantable material to treat incontinence, the instrument comprising:
- a handle,
- a 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 1.25 to 5 inches,
- an angle between the axis of the needle end portion, and a circle having an origin at the longitudinal axis and a radius defined by the needle distal end, when viewed along the longitudinal axis, is less than 15 degrees.
