Definitions
- This invention relates to the field of surgical instruments and more particularly to a device for gripping sutures during arthroscopic surgery.
- Arthroscopic surgery is a surgical procedure performed on a joint of the body, the instruments working through a small slit in the skin.
- the suture passer includes a body, from which two mechanisms protrude: a hollow needle through which a suture is guided, the suture exiting at the surgical site; and a sliding hollow tube with a distal opening, exposing a resilient member.
- the resilient member is intentionally over-extended, which causes the resilient member to bow outward and protrude from the distal opening of the sliding hollow tube.
- a suture is introduced into the resulting gap between the sliding hollowing tube and resilient member, the resilient member then allowed to retract back into place, thereby clamping the suture.
- the hollow needle of the suture passer is fixed with respect to the body and handle.
- the surgeon may manipulate the handle in order to control the hollow needle.
- the hollow needle has multiple fixed positions with respect to the handle to provide the surgeon with placement options.
- the suture is inserted into a first end of the hollow needle through a hole in the body or handle.
- the suture follows the interior of the hollow needle, exiting into the surgical site at the suture exit. Prior to the exit is preferably located a curve.
- the curve shifts the direction of the hollow needle, and correspondingly the suture, to point toward the clamping location of the resilient member. This curve is not required, as in alternative embodiments the sliding hollow tube of the retrieval member is curved.
- the hollow needle optionally includes a cutting tip to help pass the suture material through tissue.
- the retrieval member is formed from a sliding hollow tube and an internal resilient member.
- the resilient member is formed from a flexible material with a particular shape, generally linear. When the resilient member is deformed, it creates a force to try to return itself to its original shape.
- the hollow tube and resilient member are controlled by a split actuator that slides within a slot along the handle. Inside the handle the split actuator connects to an end of the hollow tube and an end of the resilient member
- a proximal portion of the split actuator connects to the hollow tube, and a distal portion of the split actuator connects to the resilient member. Initially, the two portions of the split actuator move together. Then the proximal actuator contacts a stop on the handle, stopping the distal opening of the hollow tube at the ideal location to receive a suture.
- the body of the suture passer is preferably plastic, but may be formed from other materials such as metal.
- the hollow needle sliding hollow tube is preferably formed from surgical stainless steel, such as 316, 420, or 440 stainless steel. But other materials are acceptable.
- the resilient member is preferably a wire formed from nickel titanium, also referred to as Nitinol wire.
- Nitinol is a metal alloy of nickel and titanium in which the two elements are present in roughly equal atomic percentages.
- Nitinol is readily able to return to its original shape after bending, stretching, and twisting.
- Nitinol displays recoverable strains that are more than an order of magnitude greater than in traditional alloys.

Abstract
Description
- This application is a continuation of U.S. Pat. App. Ser. No. 62/622,057, filed Jan. 25, 2018, titled Novel suture passing and retrieving device to pass and retrieve suture and other filamentary material in arthroscopic surgery.
- This invention relates to the field of surgical instruments and more particularly to a device for gripping sutures during arthroscopic surgery.
- Arthroscopic surgery is a surgical procedure performed on a joint of the body, the instruments working through a small slit in the skin.
- Patients who receive arthroscopic surgery, as compared to traditional surgery with its large incisions, experience decreased recovery time and a reduced number of complications.
- But the limitations of arthroscopic surgery imposed on the surgeon, including confined access created by small incisions and decreased working volume, create issues for surgeons. For example, a surgeon's hands cannot directly reach into the surgical site to retrieve a suture or tie a knot. The result is that the complexity, from the perspective of the surgeon, is increased.
- Given that conventional needle and suture thread cannot access the surgical site, an alternative is needed.
- What is needed is a simple, reliable device that allows suture to be passed to the surgical site, and then manipulated in-place, for use within surgical sites with limited access.
- The suture passer includes a body, from which two mechanisms protrude: a hollow needle through which a suture is guided, the suture exiting at the surgical site; and a sliding hollow tube with a distal opening, exposing a resilient member.
- To grip a suture, the resilient member is intentionally over-extended, which causes the resilient member to bow outward and protrude from the distal opening of the sliding hollow tube. A suture is introduced into the resulting gap between the sliding hollowing tube and resilient member, the resilient member then allowed to retract back into place, thereby clamping the suture.
- The hollow needle of the suture passer is fixed with respect to the body and handle. Thus, the surgeon may manipulate the handle in order to control the hollow needle. In alternative embodiments the hollow needle has multiple fixed positions with respect to the handle to provide the surgeon with placement options.
- To pass a suture to the surgical site, the suture is inserted into a first end of the hollow needle through a hole in the body or handle. The suture follows the interior of the hollow needle, exiting into the surgical site at the suture exit. Prior to the exit is preferably located a curve. The curve shifts the direction of the hollow needle, and correspondingly the suture, to point toward the clamping location of the resilient member. This curve is not required, as in alternative embodiments the sliding hollow tube of the retrieval member is curved. The hollow needle optionally includes a cutting tip to help pass the suture material through tissue.
- The retrieval member is formed from a sliding hollow tube and an internal resilient member. The resilient member is formed from a flexible material with a particular shape, generally linear. When the resilient member is deformed, it creates a force to try to return itself to its original shape.
- The hollow tube and resilient member are controlled by a split actuator that slides within a slot along the handle. Inside the handle the split actuator connects to an end of the hollow tube and an end of the resilient member
- A proximal portion of the split actuator connects to the hollow tube, and a distal portion of the split actuator connects to the resilient member. Initially, the two portions of the split actuator move together. Then the proximal actuator contacts a stop on the handle, stopping the distal opening of the hollow tube at the ideal location to receive a suture.
- Further motion of the split actuator moves only the distal portion of the actuator, thereby allowing over-extension of the resilient member, causing deformation of the resilient member, creating a gap to at the distal opening to receive a suture.
- Regarding materials, the body of the suture passer is preferably plastic, but may be formed from other materials such as metal.
- The hollow needle sliding hollow tube is preferably formed from surgical stainless steel, such as 316, 420, or 440 stainless steel. But other materials are acceptable.
- The resilient member is preferably a wire formed from nickel titanium, also referred to as Nitinol wire. Nitinol is a metal alloy of nickel and titanium in which the two elements are present in roughly equal atomic percentages. Nitinol is readily able to return to its original shape after bending, stretching, and twisting. Nitinol displays recoverable strains that are more than an order of magnitude greater than in traditional alloys.
- An example of a suitable material is a Nitinol wire with a diameter of 0.05″ and a circular cross-section. Preferably spring tempered with a tensile strength of 181,000 psi.

Throughout the following detailed description, the same reference numerals refer to the same elements in all figures.
- Referring to
FIG. 1 , an isometric view is shown of a first embodiment of the suture passer 1 with theretrieval member 60 fully retracted, and thus not shown. - The suture passer 1 is formed from a
body 10, which includes agrip 12 andguard 14. - Past the
guard 14 are two holes that pass through thebody 10—anupper hole 20 for the retrieval member and alower hole 22 for the hollow needle. - A
slot 30 at the top of thebody 10 guides the movement of asplit actuator 90. Astop 32 is placed along the path of theslot 30, thestop 32 interacting with thesplit actuator 90, as discussed further below. - The
hollow needle 40 begins at asuture entrance 42, which is visible through asuture hole 16 in thebody 10. Thehollow needle 40 continues, passing through thelower hole 22, away from thebody 10. The hollow needle changes direction at acurved guide 44 portion, terminating at thesuture exit 46 with cuttingtip 48. - Referring to
FIG. 2 , an isometric view is shown of a first embodiment of the suture passer 1 with theretrieval member 60 fully extended, and theresilient member 80 in a closed state. - The
retrieval member 60 is extended through theupper hole 20, the slidinghollow tube 62 containing aresilient member 80, visible at theopening 64, also referred to asdistal opening 64. The retrieval member ends in atip 66. Theresilient member 80 is optionally terminated at thetip 66, inside of the slidinghollow tube 62. - In this extended position, the
proximal actuator 92 of thesplit actuator 90 rests against thestop 32. Any further movement of thedistal actuator 94, which is not limited by thestop 32, will result in over-extension of the resilient member and a resulting protrusion of the resilient member from theopening 64. - Referring to
FIG. 3 , a close-up is shown of the interaction of the cuttingtip 48 of thehollow needle 40 andretrieval member 60, with theresilient member 80 in a closed state. - As in
FIG. 2 , thesplit actuator 90 rests at thestop 32, and thedistal actuator 94 has not yet been moved beyond that point in theslot 30. Thus, theresilient member 80 is in a resting state. - The gripping
face 68, or an inner portion of the slidinghollow tube 62 exposed at theopening 64, is visible. - Referring to
FIG. 4 , a close-up is shown of the interaction of the cuttingtip 48 of thehollow needle 40 andretrieval member 60, with theresilient member 80 in an open state. - With the
resilient member 80 over-extended, theresilient member 80 protrudes through theopening 64, ordistal opening 64, in the slidinghollow tube 62, creating agap 86. The exposed portion of the inside of the slidinghollow tube 62 is thegripping face 68. - Referring to
FIG. 5 , a close-up is shown of the interaction of the cuttingtip 48 of thehollow needle 40 andretrieval member 60, with theresilient member 80 in an open state, asuture 110 exiting thehollow needle 40. - When the user releases the pressure applied to the distal actuator 94 (see
FIG. 5 ), thegap 86 will close, gripping thesuture 110 between theresilient member 80 and thegripping face 68. - Referring to
FIG. 6 , a cross-section of the suture passer 1 is shown, showing the interaction of thesplit actuator 90 andretrieval member 60. - Within the
body 10, theproximal actuator 92 of thesplit actuator 90 interfaces with the slidinghollow tube 62. Thedistal actuator 94 of thesplit actuator 90 interfaces with theresilient member 80. - Also shown is the
grip 12,guard 14, andhollow needle 40. - Referring to
FIG. 7 , a cross-section is shown of the suture passer 1, showing the path of thehollow needle 40 passing through thehandle 12 of thebody 10 of the suture passer 1. - The
