As used herein, the terms parallel and perpendicular are understood to include relative configurations that are substantially parallel and substantially perpendicular up to about +/−10 degrees from true parallel and true perpendicular.
Embodiments of the presently disclosed surgical devices, coupling assemblies, adapter assemblies, and surgical attachments are described in detail with reference to the drawings, in which like reference numerals designate identical or corresponding elements in each of the several views. As used herein the term “distal” refers to that portion of the surgical device, coupling assembly or adapter assembly, or component thereof, farther from the user. The term “proximal” refers to that portion of the surgical device, coupling assembly or adapter assembly, or component thereof, closer to the user.
As mentioned above, handle housing 102 includes an upper housing portion 102 a extending between a proximal end 110 and a distal end 112. Upper housing portion 102 a houses various components of surgical device 100. Handle housing 102 further includes a lower hand grip portion 102 b extending from upper housing portion 102 a. In embodiments, lower hand grip portion 102 b may be disposed distally of a proximal-most end of upper housing portion 102 a. In some embodiments, lower hand grip portion 102 b has various surface features, such as, for example, knurled, smooth, rough, and/or textured to enhance a practitioner's gripping of lower hand grip portion 102 b.
Surgical device 100 includes at least one drive shaft rotatably disposed within housing 102 for transmitting a torque from a motor of drive mechanism 122 along a pathway to surgical attachment 400. The at least one drive shaft defines a longitudinal axis “X1”-“X1” and includes three rotatable drive shafts 118, 120, 122 that extend along and from connection portion 108. Rotatable drive shafts 118, 120, 122 may be vertically and horizontally spaced from one another. In some embodiments, rotatable drive shafts 118, 120, 122 are arranged and spaced in a common plane (i.e., only vertically or horizontally spaced) with one another such that rotatable drive shafts 118, 120, 122 are aligned in a symmetrical configuration. Additionally, in the embodiment illustrated in FIGS. 2 and 3, it is contemplated that second and third drive shafts 120, 122 may be spaced an equal distance and/or opposed directions from first drive shaft 118. It is contemplated that rotatable drive shafts 118, 120, 122 may be arranged in various orientations relative to one another, such as, for example, those alternatives described herein below. In some embodiments, handle housing 102 and connection portion 108 may house fewer or more than three rotatable drive shafts.
As will be described in greater detail below, when coupling assembly 200 is mated to surgical device 100, each of rotatable drive shafts 118, 120, 122 of surgical device 100 couples with a corresponding first, second and third gear shafts 218 a, 220 a, 222 a of coupling assembly 200, as described herein below. In this regard, the interface between corresponding first drive shaft 118 and first gear shaft 218 a, the interface between corresponding second drive shaft 120 and second gear shaft 220 a, and the interface between corresponding third drive shaft 122 and third gear shaft 222 a are keyed to one another such that rotation of each of rotatable drive shafts 118, 120, 122 of surgical device 100 causes a corresponding rotation of the corresponding gear shafts 218 a, 220 a, 222 a of coupling assembly 200. The mating of rotatable drive shafts 118, 120, 122 of surgical device 100 with gear shafts 218 a, 220 a, 222 a of coupling assembly 200 allows rotational forces to be independently transmitted via each of the three respective drive shaft/gear shaft interfaces.
Distal ends of rotatable drive shafts 118, 120, 122 may each define a recess configured to matingly engage proximal ends of first, second and third gear shafts 218 a, 220 a, 222 a of coupling assembly 200. The recesses of rotatable drive shafts 118, 120, 122 and proximal ends of gear shafts 218 a, 220 a, 222 a may have non-circular transverse cross-sectional profiles. In some embodiments, various configurations of the recesses of the rotatable drive shafts 118, 120, 122 and the proximal ends of gear shafts 218 a, 220 a, 222 a are contemplated, such as, for example, triangular, square, rectangular, oval, tapered, oblong, star-shaped, kidney-bean shaped, and/or polygonal. Alternatively, a coupling sleeve (not shown) may be used to interconnect distal ends of drive shafts 118, 120, 122 to corresponding proximal ends of gear shafts 218 a, 220 a, 222 a.
Since each of rotatable drive shafts 118, 120, 122 of surgical device 100 has a keyed and/or substantially non-rotatable interface with respective gear shafts 218 a, 220 a, 222 a of coupling assembly 200, when coupling assembly 200 is coupled to surgical device 100, rotational force(s) are selectively transferred from rotatable drive shafts 118, 120, 122 of surgical device 100 to corresponding gear shafts 218 a, 220 a, 222 a of coupling assembly 200.
The selective rotation of rotatable drive shafts 118, 120 and/or 122 of surgical device 100 allows surgical device 100 to selectively actuate different functions of surgical attachment 400 via coupling assembly 200 and adapter assembly 300. For example, selective and independent rotation of first rotatable drive shaft 118 of surgical device 100 corresponds to the selective and independent opening and closing of tool assembly 404 (see FIG. 4) of surgical attachment 400, and driving of a stapling/cutting component of tool assembly 404 of surgical attachment 400. As an additional example, the selective and independent rotation of second rotatable drive shaft 120 of surgical device 100 corresponds to the selective and independent articulation of tool assembly 404 of surgical attachment 400 transverse to a longitudinal axis “X3”-“X3” (see FIG. 2) defined between opposite ends of adapter assembly 300. Additionally, for instance, the selective and independent rotation of third rotatable drive shaft 122 of surgical device 100 corresponds to the selective and independent rotation of surgical attachment 400 about longitudinal axis “X3”-“X3” relative to handle housing 102 of surgical device 100.
First connector 230 includes a mating part, such as, for example, female mating part 236, disposed at a proximal end thereof. Female mating part 236 is configured for mating engagement with connection portion 108 of surgical device 100, as described herein. Female mating part 236 and connection portion 108 are configured for connection in a snap fit engagement. In some embodiments, female mating part 236 and connection portion 108 are connected via alternative engagement mechanisms, such as, for example, threaded engagement, frictional engagement, lock and key engagement, latches, buttons, bayonet-type connections, welding, adhesives and/or other mechanisms. It is contemplated that coupling assembly 200 and surgical device 100 may be connected so that relative rotation is resisted and/or prevented. Female mating part 236 is oriented in a first direction, as indicated by arrow “B” in FIG. 3, facing distal end 112 or connection portion 108 of surgical device 100.
As described briefly above, first connector 230 includes a first gear shaft 218 a, a second gear shaft 220 a, and a third gear shaft 222 a, each being disposed in cavity 234 of first connector 230. Proximal ends of gear shafts 218 a, 220 a, 222 a are configured for connection to first, second and third rotatable drive shafts 118, 120, 122 of surgical device 100, respectively. Distal ends of gear shafts 218 a, 220 a, 222 a are rotatably supported in or on a distal end wall 238 of first connector 230.
Gear shafts 218 a, 220 a, 222 a include first, second and third gears 240, 242, 244, respectively, non-rotatably supported thereon. Gears 240, 242, 244 are circumferentially disposed about respective first, second and third gear shafts 218 a, 220 a, 222 a. Gears 240, 242, 244 are configured for meshing engagement with first gears 260 a, 262 a, 264 a of a first, second and third rotatable drive shafts 218 b, 220 b, 222 b of coupling assembly 200, respectively, as described herein below.
Gears 240, 242, 244 can be spaced horizontally along longitudinal axis “X1”-“X1” relative to one another so that first gear 240 is disposed distal or proximal of second gear 242, and second gear 242 is disposed distal or proximal of third gear 244. In addition to gears 240, 242, 244 being spaced horizontally relative to one another, gears 240, 242, 244 may also be spaced vertically and radially relative to one another such that gears 240, 242, 244 are staggered (i.e., gears 240, 242, 244 are spaced in three dimensions) relative to one another. In some embodiments, gears 240, 242, 244 are in vertical alignment.
With continued reference to FIGS. 1-3, outer tube 250 of coupling assembly 200 extends between and has a first end 254 and a second end 256 defining a longitudinal axis “X2”-“X2” therebetween. Longitudinal axis “X2”-“X2” extends transversely, at an angle “a,” relative to longitudinal axis “X1”-“X1” of surgical device 100 when coupling assembly 200 is connected to surgical device 100. First end 254 is connected to and supports first connector 230. Second end 256 is connected to and supports second connector 270. Second connector 270 defines a longitudinal axis “X3-X3” that extends transversely, at an angle “β,” from longitudinal axis “X2”-“X2” of outer tube 250. In one embodiment, outer tube 250 extends at an angle less than about 90 degrees, preferably less than about 60 degrees, relative to longitudinal axis “X1”-“X1” of surgical device 100 and/or longitudinal axis “X3”-“X3” of second connector 270.
Coupling assembly 200 includes a first, second and third rotatable drive shafts 218 b, 220 b, 222 b disposed in passageway 252 and extending through a length of outer tube 250. First, second and third rotatable drive shafts 218 b, 220 b, 222 b of outer tube 250 are interconnected between and in operative engagement with first, second and third gear shafts 218 a, 220 a, 222 a of first connector 230, respectively, and a first, second, and third gear shafts 218 c, 220 c, 222 c of second connector 270. Rotatable drive shafts 218 b, 220 b, 222 b are substantially parallel relative to one another and spaced in a similar manner described above with regard to first, second and third gear shafts 218 a, 220 a, 222 a of first connector 230.
First rotatable drive shaft 218 b of coupling assembly 200 supports a first gear 260 a that is disposed adjacent first connector 230. First gear 260 a is configured for connection with first rotatable drive shaft 118 of surgical device 100 via geared engagement with first gear 240 of first gear shaft 218 a. First gear 240 of first gear shaft 218 a and first gear 260 a of first rotatable drive shaft 218 b are engaged with one another such that the transmission of torque therebetween is permitted. In some embodiments, first gear 240 of first gear shaft 218 a and first gear 260 a of first rotatable drive shaft 218 b are variously angled relative to one another, such as, for example, obtusely, acutely, or orthogonally. First rotatable drive shaft 218 b of coupling assembly 200 supports a second gear 260 b that is disposed adjacent second connector 270. Second gear 260 b is configured for connection with a first rotatable drive shaft 318 of adapter assembly 300 via geared engagement with a first gear 280, non-rotatably supported on a first gear shaft 218 c, of second connector 270, as will be described in detail herein below.
Second rotatable drive shaft 220 b of coupling assembly 200 supports first gear 262 a that is disposed adjacent first connector 230, below first gear 260 a of first rotatable drive shaft 218 b. First gear 262 a of second rotatable drive shaft 220 b is configured for connection with second rotatable drive shaft 120 of surgical device 100 via geared engagement with second gear 242 of second gear shaft 220 a. Second rotatable drive shaft 220 b supports a second gear 262 b that is disposed adjacent second connector 270, below second gear 260 b of first rotatable drive shaft 218 b. Second gear 262 b of second rotatable drive shaft 220 b is configured for connection with a second rotatable drive shaft 320 of adapter assembly 300 via geared engagement with a second gear 282, non-rotatably supported on a second gear shaft 220 c, of second connector 270, as will be described in detail herein below.
Third rotatable drive shaft 222 b of coupling assembly 200 supports first gear 264 a that is disposed adjacent first connector 230, below first gear 262 a of second rotatable drive shaft 220 b. First gear 264 a of third rotatable drive shaft 222 b is configured for connection with third rotatable drive shaft 122 of surgical device 100 via geared engagement with third gear 244 of third gear shaft 222 a. Third rotatable drive shaft 222 b supports a second gear 264 b that is disposed adjacent second connector 270, below second gear 262 b of second rotatable drive shaft 220 b. Second gear 264 b of third rotatable drive shaft 222 b is configured for connection with a third rotatable drive shaft 322 of adapter assembly 300 via geared engagement with a third gear 284, non-rotatably supported on third gear shaft 222 c of second connector 270, as will be described in detail herein below.
In use, a rotation of first, second and third rotatable drive shafts 118, 120, 122 of surgical device 100 results in rotation of first, second and third rotatable drive shafts 318, 320, 322 of adapter assembly 300 via first, second and third rotatable drive shafts 218 b, 220 b, 222 b of coupling assembly 200, respectively.
Second connector 270 includes a mating part 278 configured for mating engagement with a mating part 302 of adapter assembly 300. Mating parts 278, 302 are configured for connection in a snap fit engagement. In some embodiments, mating parts 278, 302 are connected via alternative engagement mechanisms, such as, for example, threaded engagement, frictional engagement, lock and key engagement, latches, buttons, bayonet-type connections, welding, adhesives and/or other mechanisms. It is contemplated that coupling assembly 200 and adapter assembly 300 may be connected so that relative rotation is resisted and/or prevented. Mating part 278 of coupling assembly 200 is oriented in a second direction, as indicated by arrow “C” in FIG. 3, facing toward adapter assembly 300 and away from surgical device 100 such that mating parts 236, 278 of first and second connectors 230, 270 are disposed on opposite sides of outer tube 250.
As described above, second connector 270 includes a first gear shaft 218 c, a second gear shaft 220 c, and a third gear shaft 222 c, each being disposed in cavity 276. First, second and third gear shafts 218 c, 220 c, 222 c are connectible between first, second and third rotatable drive shafts 318, 320, 322 of adapter assembly 300 and second gears 260 b, 262 b, 264 b of first, second and third rotatable drive shafts 218 b, 220 b, 222 b of outer tube 250, respectively. Distal ends of gear shafts 218 c, 220 c, 222 c are configured for engagement with rotatable drive shafts 318, 320, 322 of adapter assembly 300, respectively. Proximal ends of gear shafts 218 c, 220 c, 222 c are rotatably supported in or on a proximal end wall 272 of second connector 270. Gear shafts 218 c, 220 c, 222 c include a first, a second and a third gear 280, 282, 284, respectively. Gears 280, 282, 284 are non-rotatably supported on respective first, second, and third gear shafts 218 c, 220 c, 222 c, respectively. Gears 280, 282, 284 are configured for engaging second gears 260 b, 262 b, 264 b of first, second and third rotatable drive shafts 218 b, 220 b, 222 b of coupling assembly 200, respectively.
In some embodiments, gears 280, 282, 284 of gear shafts 218 c, 220 c, 222 c are spaced horizontally relative to one another along longitudinal axis “X3”-“X3” so that first gear 280 is disposed proximal or distal of second gear 282, and second gear 282 is disposed proximal or distal of third gear 284. In addition to gears 280, 282, 284 being spaced horizontally relative to one another, gears 280, 282, 284 may also be spaced vertically and radially relative to one another such that gears 280, 282, 284 are staggered (i.e., gears 280, 282, 284 are spaced in three different dimensions) relative to one another. In some embodiments, gears 280, 282, 284 are non-rotatably supported about their respective gear shafts 218 c, 220 c, 222 c in various spatial positions relative to one another. In some embodiments, gears 280, 282, 284 are aligned vertically along an axis perpendicular to longitudinal axis “X3”-“X3.”
In use, female mating part 236 of first connector 230 of coupling assembly 200 is matingly engaged to connection portion 108 of upper housing portion 102 a of surgical device 100. Coupling assembly 200 extends at an angle “α,” such as, for example, an angle less than about 90 degrees relative to distal end 112 of upper housing portion 102 a of surgical device 100 such that second connector 270 is disposed proximal of distal end 112 of upper housing portion 102 a of surgical device 100 or proximal of first connector 230. In this way, surgical system 10 has a reduced overall length defined between a proximal-most end of surgical device 100 and a distal-most end of surgical attachment 400 as a result of the use of coupling assembly 200.
Adapter assembly 300 includes first, second and third rotatable drive shafts 318, 320, 322 configured to convert a rotational force of first, second and third gear shafts 218 c, 220 c, 222 c of second connector 270 of coupling assembly 200 into an axial force for actuating surgical attachment 400, as described herein below. Drive shafts 318, 320, 322 are arranged in a staggered configuration, similar to that described above with regard to first, second and third gear shafts 218 c, 220 c, 222 c of second connector 270 of coupling assembly 200.
Proximal ends of rotatable drive shafts 318, 320, 322 each define a recess configured to matingly engage distal ends of first, second and third gear shafts 218 c, 220 c, 222 c of second connector 270. The recesses of rotatable drive shafts 318, 320, 322 and distal ends of gear shafts 218 c, 220 c, 222 c have non-circular configurations. In some embodiments, various configurations of the recesses and the distal ends of gear shafts 218 c, 220 c, 222 c are contemplated, such as, for example, triangular, square, rectangular, oval, tapered, oblong, star-shaped, kidney-bean shaped, and/or polygonal.
Proximal ends of rotatable drive shafts 318, 320, 322 may each define a recess configured to matingly engage distal ends of first, second and third gear shafts 218 c, 220 c, 222 c of coupling assembly 200. The recesses of rotatable drive shafts 318, 320, 322 and distal ends of gear shafts 218 c, 220 c, 222 c may have non-circular transverse cross-sectional profiles. In some embodiments, various configurations of the recesses of the rotatable drive shafts 318, 320, 322 and the distal ends of gear shafts 218 c, 220 c, 222 c are contemplated, such as, for example, triangular, square, rectangular, oval, tapered, oblong, star-shaped, kidney-bean shaped, and/or polygonal. Alternatively, a coupling sleeve (not shown) may be used to interconnect proximal ends of drive shafts 318, 320, 322 to corresponding distal ends of gear shafts 218 c, 220 c, 222 c.
Each drive shaft 318, 320, 322 functions as a rotation receiving member to receive rotational forces from respective gear shafts 218 c 220 c, 222 c of second connector 270 during actuation of motors of surgical device 100. Distal ends of rotatable drive shafts 318, 320, 322 are operatively engaged with force transmitting/converting members of adapter assembly 300 such that rotatable drive shafts 318, 320, 322 of adapter assembly 300 transmit rotational forces or convert rotational forces into axial forces for actuating surgical attachment 400.
As shown in FIG. 4, system 10 further includes surgical attachment 400, which is configured for operative connection with a distal end of adapter assembly 300. In the illustrated embodiment, surgical attachment 400 extends between a proximal body portion 402 connected to outer body 306 of adapter assembly 300 and a distal tool assembly 404. Surgical attachment 400 is rotatable relative to outer body 306 about longitudinal axis “X3”-“X3.” Tool assembly 404 includes a cartridge assembly 406 and an anvil assembly 408. Cartridge assembly 406 includes a stapling and cutting cartridge. Cartridge assembly 406 and anvil assembly 408 are pivotable relative to one another to clamp or unclamp material, such as, for example, tissue, therebetween.
Reference may be made to U.S. Patent Publication No. 2009/0314821, filed on Aug. 31, 2009, entitled “TOOL ASSEMBLY FOR A SURGICAL STAPLING DEVICE” for a detailed discussion of the construction and operation of surgical attachment 400, as illustrated in FIG. 4.
In assembly, operation and use, as described briefly above, female mating part 236 of first connector 230 of coupling assembly 200 is matingly engaged to connection portion 108 of upper housing portion 102 a of surgical device 100. Coupling assembly 200 extends at an angle “α,” such as, for example, an angle less than about 90 degrees relative to distal end 112 of upper housing portion 102 a of surgical device 100 such that second connector 230 is disposed proximal to distal end 112 of upper housing portion 102 a of surgical device 100.
The motors housed in surgical device 100 are selectively actuated, driving the independent rotation of first, second and third rotatable drive shafts 118, 120, 122 of surgical device 100. The rotation of first, second and third rotatable drive shafts 118, 120, 122 of surgical device 100 causes the rotation of first, second and third gear shafts 218 a, 220 a, 222 a of first connector 230, respectively, via the keyed/non-circular interface, described herein above.
In turn, toothed outer surfaces of first, second and third gears 240, 242, 244 of first, second and third gear shafts 218 a, 220 a, 222 a engage and drivingly rotate first gears 260 a, 262 a, 264 a of first, second and third rotatable drive shafts 218 b, 220 b, 222 b of outer tube 250. First, second and third rotatable drive shafts 218 b, 220 b, 222 b of coupling assembly 200 rotate within passageway 252 of outer tube 250 to transmit torque from a first axis of rotation, such as, for example, longitudinal axis “X1”-“X1”, to a second axis of rotation, such as, for example, longitudinal axis “X2”-“X2”, which is angled relative to longitudinal axis “X1”-“X1.”
In turn, toothed outer surfaces of second gears 260 b, 262 b, 264 b of first, second and third rotatable drive shafts 218 b, 220 b, 222 b of coupling assembly 200 engage and drivingly rotate first, second and third gears 280, 282, 284 of first, second and third gear shafts 218 c, 220 c, 222 c of second connector 270. In this way, a torque that originated about longitudinal axis “X1”-“X1” is transmitted to longitudinal axis “X3”-“X3,” which is radially spaced from longitudinal axis “X1”-“X1.”
In turn, the rotation of first, second and third gear shafts 218 c, 220 c, 222 c within cavity 276 of second connector 270 causes rotation of first, second and third rotatable drive shafts 318, 320, 322 of adapter assembly 300, respectively, via the keyed/non-circular interface, as described herein above. The rotation of first, second and third rotatable drive shafts 318, 320, 322 of adapter assembly 300 is either transmitted or converted to drive (i.e., rotate or translate) first, second and third drive shafts 418, 420, 422 of surgical attachment 400.
With reference to FIG. 5, a surgical system 500 is illustrated including a hand-held electromechanical surgical device 502, similar to surgical device 100. Surgical device 502 is connected directly to a surgical attachment, such as, for example, an adapter assembly 504, supporting an end effector, without implementing coupling assembly 200. Surgical system 500 has an overall length “L1” defined between a proximal-most end of surgical device 502 and a distal-most end of the end effector.
With reference to FIG. 6, surgical system 10 of the present disclosure is shown, which implements coupling assembly 200. With coupling assembly 200 interconnecting adapter assembly 504 (and the end effector) with surgical device 100, surgical system 10 has an overall length “L2,” which is less than length “L1” of surgical system 500. The angled configuration of coupling assembly 200 proximally shifts a position of end effector 504 relative to distal end 112 of surgical device 100. As such, coupling assembly 200 has reduced the overall length of surgical system 10 as compared to surgical system 500 and has shifted a center of gravity between the two proximally.
4. A coupling assembly as recited in claim 1, wherein the at least one drive shaft of the coupling assembly supports:
a first gear that is disposed adjacent the first connector, the first gear being configured for connection with the at least one rotatable drive shaft of the surgical device; and
