Claim Rejections - 35 USC § 102/103
The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action:
A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made.
The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows:
1. Determining the scope and contents of the prior art.
2. Ascertaining the differences between the prior art and the claims at issue.
3. Resolving the level of ordinary skill in the pertinent art.
4. Considering objective evidence present in the application indicating obviousness or nonobviousness.
Claim(s) 2-6, 8, 12-13, and 22-27, is/are rejected under 35 U.S.C. 103 as obvious over Viola et al. (US 20160310134 A1) in view of Shelton, IV et al. (US 20080029575 A1) and further in view of Schuh et al. (US 20200305989 A1).
Regarding claims 2-3 and 22, Viola et al. teaches a surgical instrument (1200), comprising:(a) a shaft (1204 and/or Housing assembly 1206 includes a proximal portion 1210); (b) an end effector (1208) operably coupled with the shaft (1204/1206/1210), the end effector including a pair of jaws (1226/1218) configured to cooperate to clamp and fasten tissue with a plurality of surgical fasteners (fig. 40) wherein the end effector (1208) is operable to staple tissue with the plurality of surgical staples (62, 64 [0102, 0140-0148], figs. 38-41);
(c) an articulation joint (1214/506) that interconnects the end effector (502/1208) with the shaft (1204/1206/1210) and is configured to provide articulation of the end effector relative to the shaft in each of a first articulation plane and a second articulation plane that are non-coplanar (at least two degrees of freedom, flexible tube and beams bend in at least two different planes that are non-coplanar [0096-0100, 0140-0148]); the articulation joint (1214/506) has a central passage (figs. 17 and 19 show central passage), the articulation joint including:
(i) a plurality of joint segments (proximal link 514 and a distal link 560 with intermediate links 518, 520, 522, 524, 526, 528, 530 and 532, [0095-100], figs. 16-19),
(ii) a plurality of articulation actuator passages (notches 556, 558, 560 and 562 in proximal link 514 and a distal link 560, four holes 572, 574, 576 and 578 in intermediate link 526) defined by the joint segments, and
(d) a plurality of articulation actuators (538, 540, 544 and 546) longitudinally translatable through the articulation actuator passages of the articulation joint to drive articulation of the end effector in the first and second articulation planes ([0095-0100]);
(e) a firing driver (590-592/594) actuatable through the end effector to deploy the surgical fasteners and thereby fasten the clamped tissue; and
(f) a first flexible driver firing actuator (flexible drive shaft 642/618 [0105]) operably coupled with a first portion (602) of the firing driver (592), and a second flexible driver firing actuator (630/640) operably coupled with a second portion of the firing driver (proximal end of 590), wherein the first and second flexible driver firing actuators (618/630) push the firing driver (590-592/594) longitudinally through the end effector while the end effector is articulated in both the first and second articulation planes concurrently ([0095-108], figs. 16-19).
Viola et al. fails to teach having (iii) first and second driver actuator passages defined by the joint segments; the first and second flexible driver firing actuators (618/630) are longitudinally translatable through the shaft and the first and second driver actuator passages (figs. 18-19), respectively, of the articulation joint.
However, Viola et al. does teach having first and second flexible driver firing actuators (flexible upper and lower beam extensions 1234 and 1236) that are longitudinally translatable through a shaft (1214/1206) and a driver actuator passage (1238, figs. 38-40), respectively, of an articulation joint (1214 [0140-0146], figs. 38-40). Viola et al. also teaches having first and second flexible driver firing actuators (Drive wires 380 and 382 and/or drive shafts 344 and 346 and cam 348) that are longitudinally translatable through a shaft (314/392 [0084-0085]) and a driver actuator passage (348, 406/408/394 and 396, figs. 10-11), respectively, of an articulation joint (314 note wires 380 and 382 bending/flexing in fig. 14-15 [0083-0091], figs. 10-15). Viola et al. also teaches an articulation section (30/32) that includes a proximal articulation shaft 34 and a distal articulation shaft 36 with a universal joint 38 connecting the two shafts (34/36) or having flexible shaft assembly 35 with a proximal portion 35a, a distal portion 35b, and a central portion 35c or having a constant-velocity knuckle joint assembly (37, [0067-0068], figs. 2-5 and 43-44).
Viola et al. fails to explicitly disclose in one embodiment (iii) first and second driver actuator passages defined by the joint segments; the first and second flexible driver firing actuators (618/630) are longitudinally translatable through the shaft and the first and second driver actuator passages (figs. 18-19), respectively, of the articulation joint.
Schuh et al. teaches a surgical instrument (200/500), comprising:(a) a shaft (205, 480, claims 9 and 12 and see fig. 32 showing effector 500 coupled to a shaft); (b) an end effector (500 [0128-0129], figs. 30-34) operably coupled with the shaft (fig. 32) with a firing driver (540) actuatable through the end effector to fasten the clamped tissue; and a first flexible firing actuator (push shafts 503) operably coupled with a first portion of the firing driver (540), and a second flexible firing actuator (push shafts 503) operably coupled with a second portion of the firing driver, wherein the first and second flexible firing actuators (push shafts 503) are longitudinally translatable through the shaft and the articulation joint to push the firing driver through the end effector while the end effector is articulated in both the first and second articulation planes concurrently to push the firing driver (540) through the end effector ([0147-0158], figs. 30-34).
Shelton et al. also teaches a surgical instrument (10, 2000 figs. 1 and 32), comprising:(a) a shaft (100/cylinder assembly 501); (b) an end effector (12/180) operably coupled with the shaft (figs. 1 and 32) and is operable to staple tissue with the plurality of surgical staples ([0137], figs. 1-4) with a firing driver (500/knife bar assembly 30) actuatable through the end effector to fasten the clamped tissue; and a flexible firing actuator (bellows 910) operably coupled with the firing driver (distal end 902 having protrusion 904 which fastens to aperture 33 of the knife bar 30, [0176], fig. 19), wherein the firing actuator (910) is longitudinally translatable through the shaft (cylinder assembly 501 [0176-0178], figs. 17-21) and an articulation joint (104/2002 with segment 2010, pivot socket 2034 and pivot trunions 519) to push the firing driver (30) through the end effector while the end effector is articulated in both the first and second articulation planes concurrently (trunions 519 pivot in a vertical/angled plane and the segment 2010/pivot socket 2034 in another lateral plane ([0193-0195], figs. 32-35).
Given the teachings of Viola et al. to have first and second flexible firing actuators that are longitudinally translatable through the shaft and a articulation joint to push the firing driver through the end effector and teaches having articulation joints that enable the end effector to be articulated in both the first and second articulation planes concurrently, it would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains to modify the firing driver with having the first and second flexible firing actuators are longitudinally translatable through the shaft and the articulation joint to push the firing driver through the end effector while the end effector is articulated in both the first and second articulation planes concurrently to have precise adjustment of the effector for more precise targeted location of the tool, greater pivoting adjustment, and/or for having more compact design (articulation joint with firing drive together) purposes as taught by Schuh et al. and Shelton et al. Also, it has been held adjustability, where needed, is not a patentable advance, and if an art-recognized need for adjustment the prior art would have been obvious and “substitution of a universal joint for the single pivot of the prior art would have been obvious” In re Stevens, 212 F.2d 197, 101 USPQ 284 (CCPA 1954).
Regarding claims 4-5, Viola et al. discloses the first and second articulation planes are non-coplanar (horizontal/vertical) and a plurality of articulation actuators that are independently drivable to actuate the end effector in respective articulation directions wherein the plurality of articulation actuators includes at least one first articulation actuator drivable to actuate the end effector in the first articulation plane, and at least one second articulation cable drivable to actuate the end effector in the second articulation plane ([0096-0100], figs. 16-19).
Regarding claims 6 and 8, Viola et al. discloses the at least one first articulation actuator (542) includes a first pair of articulation cables (546 and control wire 538), and the at least one second articulation actuator (540) includes a second pair of articulation cables (544, 548) and defining a plurality of passages therethrough, wherein the articulation and firing actuators extend through the passages (notches 556, 558, 560 and 562 and guide notches 564, 566, 568 and 570), wherein each of the articulation actuators is diametrically opposed from another of the articulation actuators about a central longitudinal axis of the articulation joint, wherein each articulation cable of the first, second, third, and fourth articulation cables (538, 540, 544 and 546) is diametrically opposed from another of the articulation cables about a central longitudinal axis of the articulation joint and the articulation joint (405) includes a first plurality of actuator passages configured to receive the first and second flexible firing actuators, and a second plurality of actuator passages configured to receive the articulation actuators ([0096-0100], figs. 16-19).
Regarding claim 12, Viola et al. discloses the first and second flexible firing actuators are slidable through the first plurality of actuator passages, wherein the first and second flexible firing actuators (540/542) are diametrically opposed about a central longitudinal axis of the articulation joint, wherein each of the articulation actuators is diametrically opposed with another of the articulation actuators about the central longitudinal axis ([0096-0100], figs. 16-19).
Regarding claim 13, Viola et al. discloses the firing driver (642/618, 1270/1256) includes a knife (592, 1264) configured to cut the clamped tissue ([0097-0108], [0140-0148], figs. 17-19 and 38-41).
Regarding claim 23, Viola et al. discloses each of the proximal joint segment, the distal joint segment, and the intermediate joint segment is annular, the articulation joint including a central passage that extends continuously along the central longitudinal axis from the proximal joint segment to the distal joint segment (proximal link 514 and a distal link 560 with intermediate links 518, 520, 522, 524, 526, 528, 530 and 532 are annular, ([0096-0100], figs. 16-19). Viola et al. also teaches an articulation section (30/32) that includes a proximal articulation shaft 34 and a distal articulation shaft 36 with a universal joint 38 connecting the two shafts (34/36) or having flexible shaft assembly 35 with a proximal portion 35a, a distal portion 35b, and a central portion 35c or having a constant-velocity knuckle joint assembly (37, [0067-0068], figs. 2-5 and 43-44).
Regarding claim 24, Viola et al. teaches the articulation joint includes an elastically deformable body ([0140-0146], figs. 38-40). Viola et al. also teaches an articulation section (30/32) that includes a proximal articulation shaft 34 and a distal articulation shaft 36 with a universal joint 38 connecting the two shafts (34/36) or having flexible shaft assembly 35 with a proximal portion 35a, a distal portion 35b, and a central portion 35c or having a constant-velocity knuckle joint assembly (37, [0067-0068], figs. 2-5 and 43-44).
