Description
~873~4 This is a division of Patent Application No. 260 ! 254, filed August 31, 1976.
One of the most common surgical procedures in the medical field is the suturing of body tissues, such as that of the stomach, in-testines, other organs, and the like. Efforts to reduce time required to perform surgical procedures and to im-prove the techniques of surgically joining tissues have resulted in the increased use of such devices as surgical staples, hemo-static clips, and the like which may be quickly applied in a precise manner. Such devices have been designed to be used with actuating instruments by means of which the device, such as a surglcal staple, is applied during a tissue-joining procedure precisely and with a minimum of effort. Present-day devices have produced excellent results in clinical use and have reduced the time required for many surgical procedures. However, in some cases, it may be highly desirable that the fastening devices be eventually absorbed by the body for physiological or other medical reasons.
It is an object of the present invention to provide a new and improved device for joining body tissues, which device may be ~abricated in a variety of lengths and sizes and which utilizes biologically absorbably material.
According to -the inven-tion, there is provided a surgical fastening device for joining sof-t body tissues, comprising, in combination, an elongated retainer strip of absorbable material having a plurality of longitudinally spaced openings and arranged to be posi-tioned on one side of the tissues to be joined, an elongated fastener strip of absorbable material having a plurality of prongs thereon arranged in longitudinally spaced, parallel relationship corresponding to the spacing of the retainer strip - 1- ~
. . .

- . . . ~, , . , , ,;
~733C~4 openings, each of the prongs arranged to be inserted through the tissues to be joined disposed between the strips and into one of the retainer strip openings to an extent such that the tissues are secured between the fastener strip and the retainer strip, means on the prongs for retaining the prongs in the openings to the extent inserted, an elongated rigid anvil member for support-ing the retainer strip during the tissue joining procedure, a rigid pusher member engageable with the fastener strip during the tissue joining procedure whereby relative movement between the anvil member and the pusher member permits the fastener strip and the retainer strip to be moved together into fastening en-gagement with the tissues.
An embodiment of the invention is shown with drawings, in which:
~igure 1 is an exploded view of the surgical fastening device embodying the invention, together with the associated parts used in conjunction therewith;
Figure 2 is an assembled view of a portion of the device of Figure l;
Figure 3 is an assembled view of another portion of the device of Figure l;
Figure 4 is a perspective view showing the device in the applied position, together with the associated parts; and Figure 5 is a view similar to Figure 4 showing the device in the applied position with the associated parts removed.
Referring now to the drawings, there is shown in Figure 5 a fastening device designed generally by the numeral 10.
The fastening device 10 is shown joining together soft body tissue portions 11, 12.
The fastening device 10 includes an elongated retainer ~7~3~
strip 13Of biologically degradable orbody absorbable material which is positioned on one side of the tissue to be joined, such as the tissue portion 12. The retainer strip 13 may be ofany suitable length in accordance wi-th the length of the joining procedure to be accomplished. Forinstance, although in the illustrated embodiment the retainer strip 13 is provided with aplurality of longitudinally spaced openings 14 extending transversely therethrough, as shown best in Figure l,it iswithin the scope of the invention to provide only one such opening 14, the strip 13 being shortened accordingly.
As shown in Figure 1, the openings 14 are preferable of conical shape, and the strip 13 may be provided with enlarged por-tions 13a adjacent the openings 14 to create uniform strength over the length of the strip.
The fastening device 10 also includes anelongated fastener strip 16 similarly ofbiodegradable or absorbable resinous material having a length substantially the same as that of the retainer strip 13. The fastener strip 16 is provided with a plurality of longitudinally spaced prongs 17 preferably formed in-tegrally therewith, the spacing of which corresponds to the spacing of the openings 14 in the retainer strip 13. It should be under-stood that, in the shortened version of the strip 13 wherein only a single opening 14 is provided, only a single prong 17is provided on the fastener strip 16.
The fastener strip 16 and retainer strip 13 are ar-ranged to be moved together into securing engagement with the tissue layers 11, 12 disposed therebe-tween, the pin points 27a and prongs 17 piercing the joined tissues and inserted in the openings 14 during the fasteneing procedure to the extent deter-mined by the thickness of the tissues between the s-trips. Means are provided on the prongs 17 for retaining the prongs in the openings 14 at the extent inserted, and, in the illustrated em-bodiment, such retaining means include one or more barbs 18, 19 ~73304 on the end of each of the prongs 17. As shown bes-t in F.igure 4, the upper surfaces 18a, 19a of the barbs 18, 19 are arranged for selective engagement with the underside 13b of the strip 13 to prevent withdrawal of the prongs 17 from the openings 14.
In order to position the strips 13, 16 in proper align-ment and for proper mating during -the tissue-joining procedure, as well as for moving the strip together into engagement, an elongated anvil member 21 of rigid material, such as metal or the like, is provided for supporting the retainer strip 13. As shown 10 best in Figure 3, the metal anvil member 21 is arranged to be .
positioned in relationship with the retainer strip 13 in engage-ment with the underside 13b and may be provided with longi-tudinally extending shaped side flanges 22 and 23 as shown in Figure 1. for preventing longitudinal and lateral displacement of the strip 13 on the anvil member 21. The anvil member 21 is also preferably provided with a plurality of longitudinally spaced openings 24, the spacing of which corresponds to the spacing of the openings 14 in the retainer strip 13. The openings 24 are arranged to accommodate the end portion of the prongs 17 pro-jecting beyond the underside 13b of the strip 13 against which the anvil 21 is positioned.
In order to align and support the fastener strip 16 for the joining procedure, a pusher member 30 is provided, as shown best in Figure 1, which is preferably in the shape of an elongated bar 26 of rigid material, such as metal or the like, which is arranged to engage the upper surface 16a of the fastener strip 16. The pusher member 30 is provided with a plurality of longi-tudinally spaced pins 27, the spacing o~ which corresponds to the spacing of the prongs 17.
The pins 27 are arranged to be inserted into corres-- ' ' ' ' ~ ' ' . . .
~0733~4 ponding axially extending central passages 28 extending through the prongs 17 of the fastener strip 16 as shown in Figure 2. In order that the prongs 17 easily pierce the tissue to be sutured during the suturing operation, the outer ends of thep ns 27 are provided with sharpened points 27a. ~he length of the pins 27 and the prongs 17 is selected so that, in the assembled relation-ship of Figure 2, the bar 26 will bear on strip 16 and serve to take up the thrust.
In carrying out a joining procedure~ the fastener strip 16 is positioned on the pusher member 30 with the pins 27 extend-ing within the passages 28 so as to maintain the prongs 17 in a rigid condition during the joining procedure. As can be under-stood, the plastic material from which the strip 16 and prong 17 are formed may not be sufficiently rigid to maintain the prongs 17 of themselves in an aligned position with the openings 14 in the strip 13 during the piercing of the tissue to be joined and the securing of the tissue between the strips 13, 16. However, with the metal pins 27 within the central passages 28 of the prongs 17 and with the points 27a of the pins 27 extending through the prongs 17 to provide sharp penetrating points, the prongs 17 are sufficiently inflexible so that they are maintained in alignment with the strip openings 14. Piercing of the tissue is facilitated by the sharp points 27a on the pins 27.
With the anvil member 21 and the retainer strip 13 assembled, as shown in Figure 3, on one side of the tissue layer 12 and the fastener strip 16 and pusher member 30 assembled as shown in Figure 2 on the other side of the tissue to be joined, such as tissue layer 11, the strips 13, lh are moved together.
The fastener strip 16 is moved toward the retainer strip 13 with the points 27a and prongs 17 piercing the tissue layers 11, 12.

The barb 18 on each of the prongs 17 then enters its associated opening 14 in strip 13, and, if so determined by the thickness of the tissue to be joined, the prongs 17 move through the open-ings 14 only to the extent wherein locking engagement results between the barbed surface 18a and the surface 13b of the retainer strip 13 as permitted by the anvil member openings 24.
If the tissue to be joined is of a thickness such that further movement of the prongs 17 in the openings 14 is required, the barbs 19 move through the openings 14 whereupon the surfaces l9a of the barbs 19 engage the surface 13b of the retainer strip 13.
The two strips 13, 16 are, therefore, now intercon-nected in an assembled relationship with the tissues secured therebetween as shown in Figure 4 completing the joininy pro-cedure. At this time, the anvil member 21 and pusher member 30 are removed leaving the strips 13, 16 in the applied position with the tissues 11, 12 secured as shown best in Figure 5.
Materials that are suitable for use as absorbable or hiodegradable fasteners inclucle cat gut (collagen derived from sheep intestinal submucosa); polyglycolic acid; polylactic acid, copolymer blends of polyglycolic and polylactic acid; reconsti-tuted collagen; erodible metallic alloys; polyesters; polyamino acids, such as casein, albumin, and the like; polyhydric alcohol polymers, such as polyvinyl alcohol, cellulose glycolic acid ethers; and esters of alpha-cyanacrylic acid r such as methyl alpha-cyanoacrylate. Polyglycolic acid is disclosed in U.S.
