This application is a continuation of U.S. patent application Ser. No. 14/199,096, filed Mar. 6, 2014, which claims the benefit of and priority to U.S. Provisional Patent Application Ser. No. 61/776,811, filed Mar. 12, 2013, the entire disclosure of which is incorporated by reference herein.
According to one embodiment of the present disclosure, the drive member includes a proximal portion, a central portion, and a distal portion, the central portion having a flexible configuration. According to another embodiment, a distal portion of the drive member defines at least one tine to engage a portion of at least one fastener of the plurality of fasteners. In yet another embodiment, the drive member is configured for deflection relative to the longitudinal axis at a rate different than that of the tubular member.
Referring additionally to FIG. 4, surgical fasteners 300 will now be described in detail. Surgical fasteners 300, as shown, are configured to be disposed within the interior channel 216 of outer tubular member 210. Surgical fasteners 300 may be loaded into outer tubular member 210 in an axially stacked column. Each surgical fastener 300 includes a head section 310, a mesh retention section 320, and a tissue-snaring section 322. Head section 310 includes a pair of opposing threaded sections 312 a, 312 b having respective radially outer head threads 314 a, 314 b, and a pair of opposing open or slotted sections 316 a, 316 b. Slotted sections 316 a, 316 b are configured to receive a respective tine 246 a of the distal driving portion 246 of drive member 240 (FIG. 3), as will be described further below. Mesh retention section 320 of surgical fastener 300 functions to lock, anchor, or otherwise retain a surgical mesh “M” (FIG. 11) onto surgical fastener 300 when surgical fastener 300 is advanced into mesh M, as will be described further below. An exemplary surgical fastener is disclosed in U.S. Patent Application Publication No. 2011/0282401 to Corradi, et al., the entire contents of which are incorporated by reference herein.
With additional reference to FIG. 3, the assembled housing half-sections 110 a, 110 b define an interior chamber within which drive gear 120 is disposed. Pinion gear 122 and bevel gear 124 are rotatably mounted, e.g., supported by a pin, axel, or dowel (not shown) within the housing half-sections 110 a, 110 b such that pinion gear 122 and bevel gear 124 are laterally adjacent and disposed in concentric relation. In this manner, drive gear 120 is arranged such that the cam 122 d protruding from the arm 122 c of the pinion gear is aligned to enter the arcuate slot 124 b of bevel gear 124 to rotate the bevel gear 124.
a tubular member extending from the handle portion;
a drive member rotatably supported in the tubular member and in the handle portion, the drive member includes a proximal portion, a central portion, and a distal portion, the distal portion of the drive member having a fork configuration including a pair of spaced apart tines defining a radial gap therebetween, the central portion being relatively more flexible as compared to at least one of the proximal portion and the distal portion; and
a plurality of non-cannulated fasteners disposed within the tubular member, wherein each fastener includes a threaded body portion and a head portion, the head portion defining a pair of opposed slotted sections, the pair of opposed slotted sections of each head portion receiving a respective one of the pair of tines of the distal portion of the drive member.
2. The surgical fastener applier of claim 1, wherein the tubular member defines a longitudinal axis, and the drive member is configured to rotate while in a deflected condition with respect to the longitudinal axis thereof.
3. The surgical fastener applier of claim 2, wherein the drive member is configured for deflection relative to the longitudinal axis at a rate different than that of the tubular member.
4. The surgical fastener applier of claim 1, wherein rotational motion of the drive member causes distal advancement of at least one fastener of the plurality of fasteners through the tubular member.
5. The surgical fastener applier of claim 1, further comprising a drive gear operatively connecting the handle portion and the drive member.
6. The surgical fastener applier of claim 5, wherein the drive gear is configured to transmit rotational motion to the drive member upon actuation of the handle portion.
7. The surgical fastener applier of claim 1, wherein the central portion of the drive member is torsionally rigid.
8. The surgical fastener applier of claim 1, wherein the central portion of the drive member permits continued rotation of the drive member in the presence of a bending load acting on the tubular member.
9. The surgical fastener applier of claim 1, wherein the tubular member includes a coiled spring circumferentially disposed about a portion of the drive member.
10. The surgical fastener applier of claim 9, wherein the coiled spring is configured to engage a portion of at least one of the plurality of fasteners.
11. A surgical fastener applier, comprising:
a stiffener member positioned within a proximal portion of the tubular member;
a coiled spring disposed within the tubular member;
a drive member rotatably supported in the tubular member and in the handle portion, the drive member includes a proximal portion, a central portion, and a distal portion, the distal portion of the drive member having a fork configuration defining a pair of spaced apart tines defining a radial gap therebetween, the central portion being radially flexible and torsionally rigid relative to at least one of the proximal portion and the distal portion; and
12. The surgical fastener applier of claim 11, wherein the tubular member defines a longitudinal axis and wherein the coiled spring has a substantially constant pitch along the longitudinal axis thereof.
13. The surgical fastener applier of claim 11, wherein the stiffener member has a different rigidity than the tubular member.
14. The surgical fastener applier of claim 11, wherein the coiled spring is configured to maintain a substantially straight condition of the tubular member.
15. The surgical fastener applier of claim 11, wherein rotational motion of the drive member causes distal advancement of at least one fastener of the plurality of fasteners through the tubular member.
16. The surgical fastener applier of claim 11, wherein at least one fastener of the plurality of fasteners is engaged with the coiled spring.
17. The surgical fastener applier of claim 11, wherein the drive member is configured for rotation in a deflected condition.
