Definitions
- the invention relates generally to suture retainers and methods of using suture retainers.
- the invention relates to suture retainers that hold a suture strand at a plurality of circumferentially spaced points about the suture retainer.
- Sutures are used for a variety of surgical purposes, such as approximation of tissue and ligation of tissue.
- the strand of suture material to be used has a needle affixed to one end.
- the needle is passed through the tissue to be approximated or ligated, forming a stitch.
- the stitch is then tensioned appropriately, and the two ends of the suture, the needle end and the non-needle end, are knotted to retain the desired tension in the stitch.
- the ends are knotted together; in other instances they may be stoppered separately, often with the aid of a clip or other device to form resistance to passage through tissue. While forming knots in suture during open surgery is a simple matter, forming knots in suture during endoscopic surgery can be very difficult.
- Suture retainers may be used in place of suture knots to prevent passage of a suture end into and through tissue and to maintain the tension applied to the suture material during the suturing procedure.

- the surgeon may sever the unused ends of the suture strand. If, however, the stitch needs to be retensioned to either increase or decrease tissue approximation or the retainer grip needs to be adjusted, the surgeon may pull the suture strand away from the tooth sets, then retension the stitch and reengage the suture strand with the suture retainer. While the illustrations show a clockwise wrapping of the suture, other embodiments of the invention may employ counterclockwise wrapping of the suture around the retainer.

Abstract
What is claimed is a suture retainer having a retainer body and a plurality of suture attachment mechanisms spaced circumferentially about the retainer body, each adapted to hold a suture strand at a discrete attachment point. One embodiment has a wheel portion and a plug portion. The wheel portion has a center aperture that the plug portion is configured to be insertable in and to engage with. The plug portion is configured to receive the non-needle end of a suture strand, securing it in place upon insertion of the plug into the wheel portion. The plug portion has a latch member extending therefrom which pushes the moveable arm into a flexed position during insertion. When the plug portion is fully inserted, the notch engagement ledge associates with the latch member and allows the moveable arm to return to a neutral position and secure the plug portion within the wheel portion.
Description
- This application claims the benefit and is a continuation of co-pending U.S. patent application Ser. No. 11/061,128, entitled Suture Retainer With Multiple Circumferentially Spaced Attachment Points And Suture Retention Method, filed on Feb. 17, 2005.
- The invention relates generally to suture retainers and methods of using suture retainers. In particular, the invention relates to suture retainers that hold a suture strand at a plurality of circumferentially spaced points about the suture retainer.
- Sutures are used for a variety of surgical purposes, such as approximation of tissue and ligation of tissue. Most generally, when placing sutures, the strand of suture material to be used has a needle affixed to one end. The needle is passed through the tissue to be approximated or ligated, forming a stitch. The stitch is then tensioned appropriately, and the two ends of the suture, the needle end and the non-needle end, are knotted to retain the desired tension in the stitch. Sometimes the ends are knotted together; in other instances they may be stoppered separately, often with the aid of a clip or other device to form resistance to passage through tissue. While forming knots in suture during open surgery is a simple matter, forming knots in suture during endoscopic surgery can be very difficult.
- Suture retainers may be used in place of suture knots to prevent passage of a suture end into and through tissue and to maintain the tension applied to the suture material during the suturing procedure. Suture clips and other suture retainers are described in the following publications: U.S. Pat. No. 5,234,449; U.S. Pat. No. 5,383,905; U.S. Pat. No. 5,391,173; U.S. Pat. No. 5,643,295; U.S. Pat. No. 5,645,553; U.S. Pat. No. 5,735,877; U.S. Pat. No. 5,845,645; U.S. Pat. No. 5,895,393; U.S. Pat. No. 6,015,428; U.S. Pat. No. 6,066,160; U.S. Pat. No. 6,231,592; and U.S. Pat. No. 6,432,123.
- The present invention provides a suture retainer with multiple circumferentially spaced attachment points. The invention also provides a suture retainer with a suture guide mechanism adapted to maintain an angle between a suture strand and a suture attachment mechanism. While the suture retainer of this invention can be used in conventional open surgeries or external surgeries, the invention is particularly useful for endoscopic suturing.
- The suture retainer according to one aspect of the invention has a retainer body and a plurality of suture attachment mechanisms spaced circumferentially about the retainer body, each of the suture attachment mechanisms (such as a pair of teeth) being adapted to hold a suture strand at a discrete attachment point. In some embodiments, each suture attachment mechanism is adapted to releasably hold the suture strand.
- In some embodiments of the invention, the suture retainer also has a suture guide mechanism, such as a projection from the retainer body, adapted to maintain an angle between the suture strand and one of the suture attachment mechanisms. The suture guide mechanism may be adapted to be a first contact point of the suture strand with the suture retainer.
- In some embodiments, the suture attachment mechanisms are needle-end suture attachment mechanisms, with the suture retainer also including a non-needle-end suture attachment mechanism adapted to hold a non-needle-end of the suture strand. The non-needle-end suture attachment mechanism may be disposed radially inward from each of the needle-end suture attachment mechanisms. Also, in some embodiments, the retainer body has a first member and a second member, with at least a portion of the second member being adapted to be inserted into the first member to form the non-needle-end suture attachment mechanism, such as a slot in the second member which interacts with the first member to hold the non-needle-end of the suture strand. The suture retainer may also have an alignment mechanism adapted to orient the second member with respect to the first member. In some embodiments, the suture retainer also has a movable connection between the first member and the second member, and in some embodiments the suture retainer has a snap connection between the first member and the second member. In some embodiments, a suture guide mechanism may project from the first and/or second member.
- Another aspect of the invention provides a method of securing a suture in a suture retainer, including the following steps: providing a suture retainer having a retainer body and a plurality of suture attachment mechanisms spaced circumferentially about the retainer body; and attaching a suture strand to the retainer body at each of the suture attachment mechanisms. In some embodiments, each suture attachment mechanism is at least a pair of teeth, with the method further including the step of inserting the suture strand between each of the pairs of teeth. The method may also include the step of releasing the suture strand from the suture attachment mechanisms after the attaching step and possibly the step of reattaching the suture strand to the suture attachment mechanisms after the releasing step.
- In some embodiments the method also includes the step of contacting the suture strand with a suture guide to maintain an angle between the suture strand and one of the suture attachment mechanisms. The contacting step may include the step of contacting with the suture guide a portion of the suture strand between a point where the suture strand leaves a tissue surface and a point where the suture strand contacts a suture attachment mechanism.
- In some embodiments, the attaching step includes the step of attaching a needle-end of the suture strand to needle-end suture attachment mechanisms, with the method further including the step of attaching a non-needle-end of the suture strand to the suture retainer. The retainer body may include a first member and a second member, and the step of attaching the non-needle-end of the suture strand may include the step of inserting at least a portion of the second member into the first member to hold the non-needle-end of the suture strand. In embodiments in which the retainer body has a movable connection between the first member and the second member, the inserting step may include the step of moving the second member about the movable connection with respect to the first member and possibly the step of snapping the first and second members together.
- Yet another aspect of the invention provides a suturing method including the steps of: attaching a first end of a suture strand to a suture retainer; contacting a tissue contact portion of the suture strand with tissue to be sutured, the tissue contact portion being disposed between the first end of the suture strand and a second end of the suture strand; and attaching the second end of the suture strand to the suture retainer at a plurality of suture attachment points spaced circumferentially about the suture retainer. In some embodiments, the step of attaching the second end of the suture strand includes the step of placing the second end of the suture strand between a plurality of pairs of teeth, each pair of teeth being disposed at one of the suture attachment points. The method may also include the step of detaching the suture strand from the suture attachment mechanisms after the attaching step and possibly the step of reattaching the suture strand to the suture attachment mechanisms after the detaching step.
- In some embodiments, the step of attaching the first end of the suture strand includes the step of inserting at least a portion of a first suture retainer body member into a second suture retainer body member. The attaching step may also include the step of placing the first end of the suture strand into a slot formed in the first suture retainer body member. The inserting step may include the step of aligning the first suture retainer body member with the second suture retainer body member, such as by rotating the second body member to align a second suture retainer body member alignment element with a first suture retainer body member alignment element.
- Some embodiments of this aspect of the invention include the step of contacting the second end of the suture strand with a suture guide to maintain an angle between the suture strand and one of suture attachment mechanisms, such as by making a first contact of the second end of the suture strand with the suture retainer.

As shown best inFIG. 7 , tooth sets 16 each have a pair of inclined facing edges 18 and 20 that diverge from the center ofwheel portion 12 toward the outer circumference ofwheel portion 12. The spacing and angle ofinclined surfaces - In the embodiments shown in
FIGS. 1-7 ,wheel portion 12 has three sets of teeth arranged about the circumference ofwheel portion 12 in a manner to produce pull angles of between about 50° and 70° for each tooth set. Pull angle is defined as the angle formed on the “pull” side of the tooth set between a suture held by the tooth set and a line normal to a plane formed by the juxtaposed edges of the teeth. The tooth sets extend radially from the center ofwheel portion 12 or may extend on an angle from a radius in order to provide the desired pull angle. In other embodiments, the suture retainer may have one, two or more than three sets of suture attachment mechanisms, such as the teeth shown in the embodiments ofFIGS. 1-7 . - A pair of plates or
flanges Plates wheel portion 12 to engage successive tooth sets.Wheel portion 12 has acentral opening 26 and analignment hole 28.Opening 26 andhole 28 mate with corresponding portions ofplug portion 14 when the suture retainer is assembled. - Plug portion has lock
arms plate 34.Lock arms cam surfaces arms wheel portion 12. Aslot 40 is formed betweenarms - Also extending from
plate 34 is a suture guide mechanism (such ashook 42 inFIG. 1 or tab 50 inFIG. 7 ) and analignment member 44.Alignment member 44 extends intoalignment hole 28 whenplug portion 14 is connected towheel portion 12. This arrangement sets the position of the suture guide mechanism (e.g., hook 42) with respect to one of the tooth sets 16 so that hook may serve as a retainer or guide for a suture strand as it enters a first tooth set 16, as described below. Other means of aligning the plug and wheel portions of the suture retainer may be used, of course, without departing from the invention. - To use the suture retainer, the non-needle-end of a suture is inserted into the
slot 40, preferably when the suture retainer is in the partially assembled configuration shown inFIG. 3 .Plug portion 14 is then advanced completely intowheel portion 12, withalignment member 44 aligned withalignment hole 28. Aslock arms opening 26, cam surfaces 36 and 38 engage the edges of opening 26 to movearms opening 26,arms arms plate 24 in a snap connection, as shown inFIGS. 1 and 7 , and the suture strand is gripped firmly, preferably in a controlled clearance space between the shaft of the plug and the bore of the wheel. - When thus assembled, the non-needle-end of the suture strand is held firmly by
suture retainer 10. The surgeon can then pass the needle and needle-end of the suture strand through and/or around the tissue 2 to be sutured or ligated, pullingsuture retainer 10 against the surface of the tissue, as shown inFIG. 8 . When the suture stitch is complete, the surgeon passes the needle-end 6 of thesuture strand 4 around and in engagement with thesuture guide mechanism 42, tensions the stitch, then guides the needle-end of the suture strand in succession into the three sets ofteeth 16, maintaining the tension in the suture strand as the surgeon progresses. If the stitch tension and suture retainer grip are satisfactory, the surgeon then may sever the unused ends of the suture strand. If, however, the stitch needs to be retensioned to either increase or decrease tissue approximation or the retainer grip needs to be adjusted, the surgeon may pull the suture strand away from the tooth sets, then retension the stitch and reengage the suture strand with the suture retainer. While the illustrations show a clockwise wrapping of the suture, other embodiments of the invention may employ counterclockwise wrapping of the suture around the retainer. - The shape and position of
hook 42 help retain the suture strand's orientation and pull angle with respect to the first set ofteeth 16 it encounters. In addition, the curved end ofhook 42 helps retain the suture strand in place after the suturing procedure has been completed. Other shapes and manners of suture strand guides may be used in place ofhook 42, such as tabs, posts, rings, etc. In addition, the suture strand guide of this invention may be used with suture retainers having one, two or more than three suture attachment mechanisms. -
FIG. 9 shows an optional feature for holding the far end of the needle-end of the suture strand after engagement with the retainer's sets of teeth. Aslot 54 is formed inplate 24 ofsuture retainer 10. The end of the suture strand may be placed withinslot 54 to provide additional retention of the suture and to maintain the retention of the suture provided by the last set of teeth before severing and removing the needle end of the suture. The slot may be tapered or parallel, as shown, and may be used with any of the embodiments of this invention. This feature may also be used to retain one end of a suture strand without regard to whether, or the manner in which, the other end of the suture strand is retained. - Another embodiment of the invention is shown in
FIGS. 10-13 .Suture retainer 60 has a wheel portion and aplug portion 64. Like the previous embodiments,wheel portion 62 has sets ofteeth 66 arranged about a circumference ofwheel portion 62. A pair of plates orflanges Wheel portion 62 also has acentral opening 72 with amovable member 74 formed inside the opening. A suture guide mechanism 76 extends fromwheel portion 62. -
Plug portion 64 has aslot 78 and agroove 80. Atab 82 extends from the top surface ofplug portion 64. Prior to insertion (or after partial insertion) ofplug 64 intowheel 62 in the direction shown by the arrow inFIG. 11 , the non-needle-end of asuture strand 86 may be inserted intoslot 78 and, if desired, wrapped aroundgroove 80 and back throughslot 78.Plug 64 is then inserted fully into opening 72 ofwheel 62 from the bottom, as shown inFIG. 11 . As it is inserted, the plug'stab 82 pushes the top of the wheel'smovable member 74 radially away from the center ofopening 72. When the plug'stab 82 reaches aspace 84 abovemovable member 74,movable member 74 moves back toward the center of opening 72, snappingplug 64 in place withinwheel 62. In this position, the non-needle-end ofsuture strand 86 is held firmly bysuture retainer 60. The suture thread may be tensioned downward, as shown inFIG. 13 . - After assembly of the suture retainer, the surgeon may then use the needle-end of the suture to perform the suturing or ligation procedure. As in the other embodiments, when the suture stitch is complete, the surgeon passes the needle-end of the suture strand around the suture guide 76, then inserts the suture strand in succession into the sets of
teeth 66. Thereafter, the surgeon may place the needle-end of the suture strand into aslot 88 formed in plate orflange 68. - In the embodiment shown in
FIGS. 10-13 , the top and bottom edges ofplug 64 lie flush with the top and bottom edges ofwheel 62. This arrangement is an optional feature of the invention. Also, it should be understood that other suture attachment mechanisms and other numbers of suture attachment mechanisms may be used in the suture retainer of this invention. -
FIGS. 14-17 show yet another embodiment of this invention.Suture retainer 100 has awheel portion 102 and aplug portion 104. Like the previous embodiments,wheel portion 102 has sets ofteeth 106 arranged about a circumference ofwheel portion 102. A pair of plates orflanges Wheel portion 102 also has acentral opening 112 with amovable arm 114 formed inside the opening. Asuture guide mechanism 116 extends fromwheel portion 112. -
Plug portion 104 has a pair ofpins 107 extending from an upper surface. When the suture retainer is assembled prior to use,pins 107 are snapped into openings formed by pairs ofarms 118 extending upward from the upper surface offlange 108 ofwheel 102 to form a hinge to allow rotational movement betweenplug 104 andwheel 102. Other forms of movable connection between the plug and wheel are also covered by this invention. -
FIG. 17 shows the arrangement ofplug 104 andwheel 102 prior to use of the suture retainer. Aloop 120 formed in the non-needle-end of a suture strand is passed up throughopening 112. The suture strand may then be wrapped one or more times aroundplug 104 with the suture strand lying in grooves 122 (and groove 123, for multiple suture wraps) formed inplug 104.Plug 104 is then rotated downward about the hinge formed by pins. 107 andarms 118. As the bottom ofplug 104 enters opening 112, anangled surface 124 ofplug 104 engages an angled surface formed on the top of atab 126 ofmovable arm 114, pushing the top ofarm 114 radially outward. Whenplug 104 has been completely inserted intowheel 102,tab 126 moves radially inward into aslot 128 formed inplug 104 to latchplug 104 in place withinwheel 102. The surgeon may then use the needle-end of the suture to perform the suturing or ligation procedure. As in the other embodiments, when the suture stitch is complete, the surgeon passes the needle-end of the suture strand around thesuture guide 116, then inserts the suture strand in succession into the sets ofteeth 106 to hold the suture in place. - The use of circumferentially spaced tooth sets provides multiple suture attachment mechanisms each at desired pull angles. This arrangement reduces the likelihood of slippage of the suture strand in the event one of the attachment points fails or provides less than 100% of the required tensioning force. Other numbers of tooth sets set at other pull angles may also be used. In addition, other attachment mechanisms may be used in place of the tooth sets described above, such as high friction surfaces, hooks, posts, rings, etc.
- The components of the device described above can be made of medically suitable metal or plastics, including bio-absorbable polymers. Example materials include stainless steel, polycarbonate and polyglycolide.
