Definitions

  • the present invention relates to a device for braiding fine denier yarns and, more particularly, to an improved braider bobbin top holder particularly suited for use with a device for braiding fine denier yarns to make surgical sutures.
  • Sutures intended for the repair of body tissues must meet certain requirements: they must be substantially non-toxic, capable of being readily sterilized, they must have good tensile strength and have acceptable knot-tying and knot-holding characteristics and if the sutures are of the bio-absorbable variety, the bio-absorption of the suture must be closely controlled.
  • Sutures have been constructed from a wide variety of materials including surgical gut, silk, cotton, polyolefins such as polypropylene, polyamides, polyesters such as polyethylene terephthalate, polyglycolic acid, glycolide-lactide copolymer, etc.
  • polyolefins such as polypropylene
  • polyamides such as polyethylene terephthalate
  • polyglycolic acid glycolide-lactide copolymer
  • sutures manufactured from such materials have been provided as braided structures.
  • sutures manufactured from silk, polyamide, polyester and bio-absorbable glycolide-lactide copolymer are usually provided as multifilament braids.
  • the present invention relates to an improved apparatus for braiding elongate flexible members to form a final braided product, preferably a surgical suture made from fine denier yarns.
  • the braided product may be of the type formed only of a tubular braided sheath, a substantially solid spiroid braid, or a tubular or spiroid braided sheath formed about a center core.
  • the present invention is directed to improvements which make it possible to quickly mount and/or remove a yarn bobbin onto or from a yarn bobbin carrier with high efficiency and speed and to secure the bobbin to the carrier with a securing mechanism which is simple to operate, does not require a high level of dexterity, and which is not tiring or injurious to the muscles of the operator.
  • a plurality of yarn bobbin carriers move about a main carrier support plate to dispense yarns toward a braiding zone where the yarns are braided together to form a final braided product, preferably a surgical suture.
  • the preferred apparatus includes means for controlling tension on the yarns dispensed from the bobbins to form the braided suture product and to control the tension on the final braided product.
  • Each yarn carrier includes a spindle onto which a novel molded bobbin having a central aperture is mounted for rotational movement relative to the spindle.
  • Each bobbin has a number of radial segments engageable with a pawl on the carrier for selectively permitting rotation of the bobbin in response to yarn tension in order to control the dispensing of yarn from the bobbin.
  • a bobbin top holder base is fixedly mounted relative to the yarn carrier adjacent the top of the yarn carrier spindle and, hence, adjacent to the top of a bobbin situated thereon.
  • the bobbin top holder base has hinge pins, and a bobbin top holder is hingedly mounted to the bobbin holder base at the hinge pins.
  • the bobbin top holder has two longitudinally extending legs defining a slot therebetween and, more specifically, a spindle engaging recess having an inwardly projecting radiused section to engage a corresponding circumferential recess in the spindle adjacent the spindle tip.
  • the bobbin holder legs are formed of a resilient plastic material which is sufficiently flexible to permit the legs to spread apart as the legs are forced over the spindle tip, and resiliently reassume a rest position disposed within the circumferential recess of the spindle to hold the bobbin on the spindle.
  • the bobbin top holder first is disposed in an unlocked or open position rotated away from the spindle to permit mounting of a bobbin loaded with yarn onto the carrier.
  • the bobbin top holder is rotated into contact with the spindle tip with sufficient force to cause the bobbin top holder legs to spread apart and mount over the spindle, resiliently resuming a rest or contracted position disposed within the circumferential recess of the spindle tip, thereby securing the bobbin on the carrier.
  • the braider apparatus thereafter is operated to form a final braided product, preferably a surgical suture.
  • the preferred bobbin holder is injection molded of an elastomeric plastic material which is sufficiently resilient to permit many cycles of bobbin mounting without failure of the bobbin top holder.
  • the bobbin holder of the invention is convenient to use and advantageously improves the efficiency of the preferred braider apparatus.
  • FIG. 1 there is illustrated an apparatus 10 for braiding sutures constructed according to the present invention.
  • the apparatus 10 is supported on frame 12 which includes a horizontal support plate 14.
  • Electrically powered motor 16 is arranged to drive the apparatus as will be described.
  • motor 16 drives carrier plates 18 around main carrier support plate 20 along a predetermined path.
  • a plurality of yarn bobbin carriers 22, only one of which is illustrated in Fig. 1 for simplicity, are mounted to carrier plates 18 and dispense yarns from yarn bobbins 24 (see Fig. 6) as the bobbins and carriers follow a predetermined path around the main carrier support plate.
  • the apparatus illustrated in Fig. 1 is designed to drive the bobbin carriers in undulating paths in opposite directions around the main carrier plate in a known manner.
  • alternate carrier path configurations also are contemplated, such as a spiral pattern in which all bobbin carriers move in the same direction around the main carrier plate.
  • Spiral braiders, per se are also known.
  • yarns 3 dispensed from each bobbin carrier station are led to a braiding zone and formed into an elongated braided suture product.
  • Tension on the braided suture product is controlled by driven tension rollers 26, 28 and take-up roller 30.
  • a core yarn bobbin 29 is mounted beneath support plate 14.
  • the optional core yarn 31 maintained under tension is led through a core yarn tension detector 33 and a hollow tube 32 to the braiding zone, such that sheath yarns from the yarn carriers mounted on main carrier plate 20 are braided about the core yarn.
  • Figs. 2-4 and 6 the yarn carrier system and yarn tensioning system is illustrated.
  • Fig. 4 there is shown a cross-sectional view of the base of a yarn carrier 22 mounted to carrier support plate 18.
  • Carrier 22 has downwardly extending connector shoes 38, 40 which extend into guide channels in the main carrier support plate 20.
  • the connector shoes traverse the respective guide channels as the yarn carrier is transferred between the respective carrier support plates 18.
  • the carriers are transported around the main carrier support plate in a spiral pattern.
  • yarn bobbin carrier 22 has a carrier housing 42 with a spindle 44 extending vertically therefrom to receivably engage bobbin 24.
  • a yarn guide support 46 also extends from carrier housing 42 in a direction substantially parallel to spindle 44, and is shown in Fig. 2 as a pair of rods 46A and 46B.
  • a yarn dispensing guide eyelet 48 preferably made from a ceramic material, is fixed to one rod.
  • a compensator eyelet 50 also preferably made from a ceramic material, slidably engages the other rod.
  • Compensator eyelet 50 is connected via a compensator rod 52 to a compensator arm 54 for controlling the dispensing of yarn in response to tension exerted by the yarn on compensator arm 54 via compensator rod 52 and eyelet 50.
  • Compensator arm 54 pivots about pivot pin 56 on carrier 22, as shown in Fig. 3.
  • End portion 58 of compensator arm 54 is connected to compensator rod 52 while the opposite end portion 60 of pivot arm 54 engages pin 62 which is biased upwardly by a light coil spring 64.
  • Pin 62 is disposed in and moves upwardly and downwardly in slot 63.
  • Pin 62 is connected to pawl 66 arranged to float into and out of radial slots 68 on the lower surface of yarn bobbin 24.
  • Pin 70 moves upwardly and downwardly in slot 72 in carrier housing 42 while traversing the moving arcuate slot 74 in compensator arm 54.
  • Pin 62 is biased upwardly by spring 64 and, in turn, biases end portion 60 upward, pivotally rotating compensator arm 54 to urge arm end 58, rod 52 and compensator eyelet 50 downwardly.
  • the upper ends of rods 46A and 46B are seated in and support a top holder support 76.
  • Top holder support 76 has two substantially parallel vertical apertures 78, 80 configured to receive rods 46A, 46B, as by frictional engagement or by an adhesive disposed therebetween (see Fig. 11).
  • Top holder support 76 includes a substantially horizontal yarn guide section 82 extending from support 76 and having a ceramic yarn guide eyelet 84 for guiding yarn dispensed from the bobbin toward the braiding zone. Top holder support 76 also has a pair of hinge pins 86, 88 (see Fig. 11) extending longitudinally therefrom in a direction substantially perpendicular to the spindle.
  • Bobbin top holder 90 has a pair of hinge pin engaging legs 92, 94. Each leg has an enlarged hinge pin receiving section 96 having a hinge pin aperture 98 configured and dimensioned to receive hinge pins 86, 88. In this manner bobbin top holder 90 is mounted to top holder support 76 and is hingedly rotatable about the axis of hinge pins 86, 88.
  • Bobbin top holder 90 has a substantially planar section 100 extending from legs 92, 94 and a pair of spindle gripping legs 102, 104 defining therebetween a slot 106 and a spindle engaging recess 108.
  • Fig. 7 is a top plan view of bobbin holder 90. Referring now to Fig. 8, a cross-sectional view of the bobbin holder taken along lines 8-8 of Fig. 7, it can be seen that spindle engaging recess 108 is configured with an outwardly tapered entrance wall 110, a substantially cylindrical barrel section 112, an inwardly projecting radiused section 114, and an outwardly tapered exit wall section 116.
  • entrance wall 110 defines an angle of about 10° to 20° relative to the axis of recess 108, and exit walls 116 define an included angle on the order of about 90°.
  • the spindle engaging recess is symetrical about its vertical axis, except for slot region 106, and is identically configured in both legs 102, 104. As shown in Fig. 8, spindle engaging recess 108 is disposed in a region 140 of legs 102, 104 of greater thickness than the remaining portions of the legs in order to provide structural support surrounding the spindle engaging recess.
  • spindle 44 is provided with a bobbin holder engaging tip 118 configured to be disposed in spindle engaging recess 108 to secure bobbin top holder 90 to spindle 44 and, hence, bobbin 24 on spindle 44 (see Fig. 6).
  • the preferred spindle tip configuration for engaging recess 108 is illustrated in Fig. 9.
  • spindle tip 118 has a spindle engaging shank 120 connected to a spindle tip body 122.
  • Spindle tip body 122 has a substantially cylindrical proximal base 124, a spindle tip recess 126 defined by a pair of inclined walls 128, 130, and a substantially frusto-conical distal tip section 132.
  • Distal tip section 132 and recess 126 may be joined by a substantially cylindrical transition section 134.
  • Shank 120 is configured to be received in a hollow recess in spindle 44 to fixedly mount spindle tip 118 to spindle 44.
  • Fixed mounting of tip 118 to spindle 44 may be accomplished by friction fit of shank 120 in the spindle recess, by providing an adhesive or combination of adhesive and friction between the shank and recess, or most preferably by providing mutually engageable threads on the shank and within the recess.
  • a slot 136 may be provided in distal tip 132 for engaging a tool, such as a screwdriver.
  • Inclined walls 128, 130 preferably define an interior angle on the order of about 90°, and the walls of frusto-conical distal tip 132 preferably define an angle of about 20° relative to the tip axis.
  • spindle tip 118 preferably is symetrical about the axis thereof.
  • Bobbin 24 is integrally constructed of a lightweight material such as molded nylon or other plastic material.
  • the bobbin includes a hollow cylindrical opening 140 configured to slidably receive spindle 44 with bobbin 24 being rotatable about the spindle (see Figs. 2 and 6).
  • bobbin 24 is mounted onto spindle 44 with the bobbin top holder 90 in the open or unlocked position, as shown in Fig. 2.
  • radial slots 68 on bobbin 24 engage pawl 66 on carrier housing 42.
  • Braiding yarn 3 is led from bobbin 24 through dispensing eyelet 48, compensator eyelet 50 and guide eyelet 84 and upward to the braiding zone (also see Fig. 6).
  • bobbin top holder 90 is rotated and locked into the position shown in Fig. 6 to hold bobbin 24 on spindle 44 during braiding.
  • yarn is drawn upwardly by the braiding system.
  • Yarn is dispensed from bobbin 24 until the tension on the yarn exceeds a predetermined value and draws compensator eyelet 50, rod 52 and compensator arm end portion 58 upward (see Figs. 2-3).
  • the opposite end 60 of arm 54 depresses pin 62 against spring 64, causing pawl 66 to withdraw from slot 68 in the bobbin 24. Removal of pawl 66 from slot 68 permits bobbin 24 to rotate about spindle 44 to dispense more yarn.
  • fine denier multifilament yarns in the range of about 0.2 to 6.0 denier are dispensed from bobbin 24, with the tension of the yarn dispensed from bobbin 24 closely controlled within a precise range.
  • the tension of the yarns is controlled within a precise range, particularly by selecting a spring 64 which is within a predetermined range of spring rates.
  • Prior art braiders utilized a spring 64 of significantly greater spring rate than is contemplated herein due to the fact that braiding was accomplished with heavier braiding materials.
  • pin 70 was also arranged to be biased downwardly by a spring positioned centrally within spindle shaft 44.
  • the central spring has been eliminated and spring 64 has been selected to have a reduced spring rate in the range of from about 0.6 to 0.7 pounds per inch.
  • the standard spring on such braiders having a much higher spring rate on the order of about 0.9 to about 1.0 pounds per inch. Reducing the spring rate reduces the tension force on the yarn necessary to cause pivot arm 54 to rotate and withdraw pawl 66 from slot 68, thereby permitting the bobbin to rotate and pay out additional yarn.
  • the reduced spring rate accommodates the relatively lower tensile strength associated with yarns of aforementioned preferred denier range suitable for producing braided sutures. The production of such sutures is thus carefully and precisely controlled to accommodate the fine character, not only of the finished braided suture, but particularly of the yarn components thereof.
  • bobbin 24 is constructed of a lightweight moldable material such as nylon and defines a central axial opening 140 extending the length of the bobbin to receive the carrier housing spindle (see Figs. 2 and 6). With bobbin holder 90 disengaged from spindle 44 and rotated away from the spindle, such as in the substantially vertical bobbin holder position shown in Fig. 2, the bobbin may be mounted over the spindle with spindle 44 received within opening 140. Referring now to Figs.
  • bobbin holder 90 is rotated about hinge pins 86, 88 until inwardly projecting radiused section 114 on each bobbin holder leg 102, 104 contact the angled surface of frusto-conical distal tip section 132.
  • contact between section 114 and tip section 132 occurs slightly before holder 90 reaches a position perpendicular to the axis of spindle 44.
  • inwardly extending radiused section 114 is disposed in recess 126 with outwardly extending exit wall 116 juxtaposed to distal recess wall 130 and the lower radiused section 114 disposed adjacent proximal inclined recess wall 128.
  • Cylindrical section 112 is disposed around spindle tip base 124. As shown in Fig. 6, the maximum diameter of tip 118 approximates the diameter of spindle 44 to facilitate mounting and removal of the bobbin onto and from the spindle.
  • bobbin top holder 90 In order to remove a bobbin from the apparatus, i.e. after all the desired yarn has been dispensed from the bobbin during braiding, upward force is exerted on bobbin top holder 90, such as at the distal areas of legs 102, 104. This causes inclined wall 130 on tip 118 to cam against exit wall 116 of recess 126 and spread apart legs 102, 104, thereby causing inwardly projecting radiused section 114 to spread apart and become disengaged from recess 126.
  • bobbin top holder legs 102, 104 resiliently return to their rest position wherein the separation distance of radiused sections 114 on each leg approximates the minimum diameter of spindle tip 118 within recess 126.
  • bobbin top holder 90 may be further rotated about hinge pins 86, 88 until holder 90 is rotated to a position such as shown in Fig. 2 out of the way to permit removal of the empty bobbin and/or placement of a new bobbin loaded with yarn to be dispensed for braiding.
  • the bobbin carrier and spindle may be made of metal, such as stainless steel, with top holder support rods 46A, 46B made from the same or different metal, e.g. aluminum, or a rigid plastic material.
  • Ceramic eyelet 48 may be mounted to rod 46B by wrapping a metal wire around both the eyelet and the rod to fix the eyelet to a central region of the rod.
  • Ceramic eyelet 50 may be mounted to rod 46A by similarly wrapping a metal wire around the eyelet and around rod 46A, to permit slidable movement of the wire relative to rod 46A.
  • compensator rod 52 is integrally formed of the same wire which connects ceramic eyelet 50 to rod 46A.
  • Top holder support 76 preferably is made of a rigid plastic material, such as nylon.
  • Top holder 90 is made of a plastic material which is sufficiently flexible and resilient to deform and permit legs 102, 104 to repeatedly be spread apart and mounted over spindle tip 118 through multiple cycles, such as an elastomeric nylon material.
  • both top holder support 76 and bobbin top holder 90 may be injection molded at relatively modest cost.
  • Spindle tip 118 should be made of a rigid metal material, such as a zinc coated steel.
  • the bobbin top holder of the present invention facilitates quick and easy placement and removal of a bobbin relative to the spindle and bobbin carrier.
  • the top holder of the invention does not require any pinching or gripping action by the user, such as to unscrew a prior bobbin holder, thereby minimizing the effort which must be exerted by the user to engage or release the bobbin top holder and reducing the time required to change bobbins on the carrier.
  • the braiding apparatus is well suited for high speed production of consistently high quality final braided suture products having an overall suture denier ranging from as low as about 50 denier to as large as about 4,000 denier.
  • Core yarns will have a preferred denier of from as low as about 20 denier to as high as about 2,400 denier, and sheath yarns will have a denier of from as low as about 0.2 denier to as high as about 6.0 denier.
