Description
BACKGROUND

A variety of surgical instruments include an end effector having a blade element that vibrates at ultrasonic frequencies to cut and/or seal tissue (e.g., by denaturing proteins in tissue cells). These instruments include piezoelectric elements that convert electrical power into ultrasonic vibrations, which are communicated along an acoustic waveguide to the blade element. The precision of cutting and coagulation may be controlled by the surgeon's technique and adjusting the power level, blade edge, tissue traction and blade pressure.

Examples of ultrasonic surgical instruments include the HARMONIC ACE® Ultrasonic Shears, the HARMONIC WAVE® Ultrasonic Shears, the HARMONIC FOCUS® Ultrasonic Shears, and the HARMONIC SYNERGY® Ultrasonic Blades, all by Ethicon Endo-Surgery, Inc. of Cincinnati, Ohio.

I. Exemplary Ultrasonic Surgical Instrument

FIG. 1 illustrates an exemplary ultrasonic surgical instrument (10). At least part of instrument (10) may be constructed and operable in accordance with at least some of the teachings of U.S. Pat. No. 5,322,055; U.S. Pat. No. 5,873,873; U.S. Pat. No. 5,980,510; U.S. Pat. No. 6,325,811; U.S. Pat. No. 6,773,444; U.S. Pat. No. 6,783,524; U.S. Pub. No. 2006/0079874; U.S. Pub. No. 2007/0191713; U.S. Pub. No. 2007/0282333; U.S. Pub. No. 2008/0200940; U.S. Pub. No. 2009/0105750; U.S. Pub. No. 2010/0069940; U.S. Pub. No. 2011/0015660; U.S. Pub. No. 2012/0112687; U.S. Pub. No. 2012/0116265; U.S. patent application Ser. No. 13/538,588; U.S. patent application Ser. No. 13/657,553; and/or U.S. Pat. App. No. 61/410,603. The disclosures of each of the foregoing patents, publications, and applications are incorporated by reference herein. As described therein and as will be described in greater detail below, instrument (10) is operable to cut tissue and seal or weld tissue (e.g., a blood vessel, etc.) substantially simultaneously. It should also be understood that instrument (10) may have various structural and functional similarities with the HARMONIC ACE® Ultrasonic Shears, the HARMONIC WAVE® Ultrasonic Shears, the HARMONIC FOCUS® Ultrasonic Shears, and/or the HARMONIC SYNERGY® Ultrasonic Blades. Furthermore, instrument (10) may have various structural and functional similarities with the devices taught in any of the other references that are cited and incorporated by reference herein.

To the extent that there is some degree of overlap between the teachings of the references cited herein, the HARMONIC ACE® Ultrasonic Shears, the HARMONIC WAVE® Ultrasonic Shears, the HARMONIC FOCUS® Ultrasonic Shears, and/or the HARMONIC SYNERGY® Ultrasonic Blades, and the following teachings relating to instrument (10), there is no intent for any of the description herein to be presumed as admitted prior art. Several teachings herein will in fact go beyond the scope of the teachings of the references cited herein and the HARMONIC ACE® Ultrasonic Shears, the HARMONIC WAVE® Ultrasonic Shears, the HARMONIC FOCUS® Ultrasonic Shears, and the HARMONIC SYNERGY® Ultrasonic Blades.

Instrument (10) of the present example comprises a handle assembly (20), a shaft assembly (30), and an end effector (40). Handle assembly (20) comprises a body (22) including a pistol grip (24) and a pair of buttons (26). Handle assembly (20) also includes a trigger (28) that is pivotable toward and away from pistol grip (24). It should be understood, however, that various other suitable configurations may be used, including but not limited to a scissor grip configuration. End effector (40) includes an ultrasonic blade (160) and a pivoting clamp arm (44). Clamp arm (44) is coupled with trigger (28) such that clamp arm (44) is pivotable toward ultrasonic blade (160) in response to pivoting of trigger (28) toward pistol grip (24); and such that clamp arm (44) is pivotable away from ultrasonic blade (160) in response to pivoting of trigger (28) away from pistol grip (24). Various suitable ways in which clamp arm (44) may be coupled with trigger (28) will be apparent to those of ordinary skill in the art in view of the teachings herein. In some versions, one or more resilient members are used to bias clamp arm (44) and/or trigger (28) to the open position shown in FIG. 1.

An ultrasonic transducer assembly (12) extends proximally from body (22) of handle assembly (20). Transducer assembly (12) is coupled with a generator (16) via a cable (14). Transducer assembly (12) receives electrical power from generator (16) and converts that power into ultrasonic vibrations through piezoelectric principles. Generator (16) may include a power source and control module that is configured to provide a power profile to transducer assembly (12) that is particularly suited for the generation of ultrasonic vibrations through transducer assembly (12). By way of example only, generator (16) may comprise a GEN 300 sold by Ethicon Endo-Surgery, Inc. of Cincinnati, Ohio. In addition or in the alternative, generator (16) may be constructed in accordance with at least some of the teachings of U.S. Pub. No. 2011/0087212, entitled “Surgical Generator for Ultrasonic and Electrosurgical Devices,” published Apr. 14, 2011, the disclosure of which is incorporated by reference herein. It should also be understood that at least some of the functionality of generator (16) may be integrated into handle assembly (20), and that handle assembly (20) may even include a battery or other on-board power source such that cable (14) is omitted. Still other suitable forms that generator (16) may take, as well as various features and operabilities that generator (16) may provide, will be apparent to those of ordinary skill in the art in view of the teachings herein.

End effector (40) of the present example comprises clamp arm (44) and ultrasonic blade (160). Clamp arm (44) includes a clamp pad that is secured to the underside of clamp arm (44), facing blade (160). Clamp arm (44) is operable to selectively pivot toward and away from blade (160) to selectively clamp tissue between clamp arm (44) and blade (160) in response to pivoting of trigger (28) toward pistol grip (24). Blade (160) of the present example is operable to vibrate at ultrasonic frequencies in order to effectively cut through and seal tissue, particularly when the tissue is being clamped between clamp arm (44) and blade (160). Blade (160) is positioned at the distal end of an acoustic drivetrain that includes transducer assembly (12) to vibrate blade (160). By way of example only, the acoustic drivetrain may be configured in accordance with various teachings of various references that are cited herein.

In the present example, the distal end of blade (160) is located at a position corresponding to an anti-node associated with resonant ultrasonic vibrations communicated through a flexible acoustic waveguide, in order to tune the acoustic assembly to a preferred resonant frequency fo when the acoustic assembly is not loaded by tissue. When transducer assembly (12) is energized, the distal end of blade (160) is configured to move longitudinally in the range of, for example, approximately 10 to 500 microns peak-to-peak, and in some instances in the range of about 20 to about 200 microns at a predetermined vibratory frequency fo of, for example, 55.5 kHz. When transducer assembly (12) of the present example is activated, these mechanical oscillations are transmitted through waveguides to reach blade (160), thereby providing oscillation of blade (160) at the resonant ultrasonic frequency. Thus, when tissue is secured between blade (160) and clamp arm (44), the ultrasonic oscillation of blade (160) may simultaneously sever the tissue and denature the proteins in adjacent tissue cells, thereby providing a coagulative effect with relatively little thermal spread. In some versions, an electrical current may also be provided through blade (160) and clamp arm (44) to also cauterize the tissue. While some configurations for an acoustic transmission assembly and transducer assembly (12) have been described, still other suitable configurations for an acoustic transmission assembly and transducer assembly (12) will be apparent to one or ordinary skill in the art in view of the teachings herein. Similarly, other suitable configurations for end effector (40) will be apparent to those of ordinary skill in the art in view of the teachings herein.

II. Exemplary Breakaway Handle Assembly

In some versions, instrument (10) includes an integral power source within handle assembly (20) such that an external generator (16) is not needed. For example, FIG. 2 shows a battery (64) housed within grip (24) of handle assembly (20) that may be coupled with transducer assembly (12) to provide electrical power to transducer assembly (12). Examples of such integral power sources are described in U.S. Pub. No. 2012/0112687, entitled “Recharge System for Medical Devices,” published May 10, 2012, the disclosure of which is incorporated by reference herein; U.S. Pub. No. 2012/0116265, entitled “Surgical Instrument with Charging Devices,” published May 10, 2012, the disclosure of which is incorporated by reference herein; U.S. patent application Ser. No. 13/804,417, entitled “Surgical Instrument with Selectable Integral or External Power Source,” filed Mar. 14, 2013, the disclosure of which is incorporated by reference herein; and/or U.S. Pat. App. No. 61/410,603, filed Nov. 5, 2010, entitled “Energy-Based Surgical Instruments,” the disclosure of which is incorporated by reference herein. In some instances, it may be desirable to allow the user to dispose of battery (64) without contacting battery (64). For example, instrument (10) may include a breakaway handle assembly such that the user may grasp handle assembly (20) to dispose of battery (64) without contacting battery (64). The examples below include several merely illustrative versions of a surgical instrument with a breakaway handle assembly that may be readily introduced to an instrument (10).

A. Exemplary Breakaway Strip Assembly

FIGS. 3A-3C show an exemplary handle assembly (120) that is similar to handle assembly (20), except that body (122) of handle assembly (120) comprises a breakaway strip assembly (125). As best seen in FIG. 3A, strip assembly (125) is positioned between body (122) and grip (124). Strip assembly (125) comprises a first strip (127) that is coupled with body (122) and a second strip (128) coupled with grip (124). Strips (127, 128) are then releasably coupled together to thereby releasably couple body (122) with grip (124) of handle assembly (120). For example, FIG. 3B shows that first strip (127) comprises a distal tab (121) and a side tab (123) positioned on each side of distal tab (121). Tabs (121, 123) may be resiliently biased outwardly such that tabs (121, 123) secure first strip (127) relative to second strip (128) when first strip (127) is coupled with second strip (128). In the present example, distal tab (121) comprises a protrusion (129) extending distally on an end portion of distal tab (121). Second strip (128) defines an opening (119) on a distal portion of second strip (128) that is configured to receive protrusion (129) of first strip (127) to further secure first strip (127) with second strip (128) when first strip (127) is coupled with second strip (128). Although three tabs (121, 123) are shown in the present example, any other suitable number of tabs (121, 123) may be used to couple first strip (127) with second strip (128). Strips (127, 128) may be co-molded and made from an elastomeric material.

During a surgical procedure, strips (127, 128) are coupled to thereby couple body (122) with grip (124). First strip (127) is configured to couple with second strip (128) such that tabs (121, 123) secure first strip (127) with second strip (128), as shown in FIG. 3A. When strips (127, 128) are secured together, strip assembly (125) provides a fluid tight seal between body (122) and grip (124) such that strip assembly (125) prevents fluids from entering handle assembly (120) at the interface of strips (127, 128) or elsewhere at strip assembly (125). When body (122) is coupled with grip (124), tabs (121, 123) may flex slightly inwardly to slide through second strip (128) and press outwardly against second strip (128). Tabs (121, 123) thereby provide a friction fit to couple first strip (127) and second strip (128). When strips (127, 128) are coupled, protrusion (129) of distal tab (121) flexes outwardly through opening (119) of second strip (128) to further secure first strip (127) relative to second strip (128) through a snap fitting. In the present example, tabs (121, 123) are configured to press against second strip (128). However, tabs (121, 123) may also slide through second strip (128) such that tabs (121, 123) press against the inner walls of grip (124) to secure body (122) with grip (124). In some versions, tabs (121, 123) press against a portion of second strip (128) and a portion of grip (124). Opening (119) may also be positioned on grip (124) such that protrusion (129) of distal tab (121) slides within the wall of grip (124) instead of second strip (128). However, it should be noted that protrusion (129) is merely optional, such that the distal wall of distal tab (121) is used to press against second strip (128) and/or grip (124). Other suitable configurations for first and second strips (127, 128) will be apparent to one with ordinary skill in the art in view of the teachings herein.

When the surgical procedure is finished, a user may separate body (122) and grip (124), as shown in FIG. 3B. The user may press protrusion (129) of distal tab (121) inwardly to remove protrusion (129) from opening (119) of second strip (127). The user may then pull grip (124) away from body (122) such that tabs (121, 123) of first strip (127) slide out of second strip (128). Battery (164) is then exposed through an opening (118) on the top portion of grip (124). Grip (124) is then grasped and tipped downwardly to remove battery (164) from grip (124) through opening (118) by allowing battery (164) to slide out of grip (124) under the influence of gravity, as shown in FIG. 3C. Accordingly, grip (124) of handle assembly (120) may be used to dispose of battery (164) such that the user does not directly contact battery (164). Grip (124) may be used to dispose of battery (164) within a battery reclamation bin. Alternatively, battery (164) may be disposed of in any other suitable fashion.

B. Exemplary Pivoting Strip Assembly

FIGS. 4A-4B show another exemplary handle assembly (220) that is similar to handle assembly (120). However, instead of a breakaway strip assembly (125), handle assembly (220) comprises a strip (228) such that grip (224) may pivot relative to body (222) to dispose of a battery (264). As shown in FIG. 4A, strip (228) is positioned between body (222) and grip (224) to releasably couple body (222) with grip (224). When strip (228) is secured with body (222) and grip (224), strip (228) provides a fluid tight seal between body (222) and grip (224) such that strip (228) prevents fluids from entering handle assembly (220) at strip (228). Strip (228) comprises a proximal portion (229) that acts as a living hinge to allow grip (224) to pivot relative to body (222). Strip (228) may be co-molded with body (222) and/or grip (224). In some versions, strip (228) is made from an elastomeric material. In other versions, a proximal portion of strip (228) comprises a rigid material such that the rigid material provides a more supportive structure for strip (228). Other configurations for strip (228) will be apparent to one with ordinary skill in the art in view of the teachings herein.

During a surgical procedure, grip (224) is coupled with body (222) via strip (228), as shown in FIG. 4A. When the procedure is finished, a user may pull grip (224) away from body (222) to separate body (222) and grip (224), as shown in FIG. 4B. In the present example, proximal portion (229) of strip (228) acts as a living hinge such that grip (224) pivots relative to body (222). When grip (224) is pivoted relative to body (222), strip (228) may break apart such that a portion of strip (228) remains with grip (224) and a portion of strip (228) remains with body (222). Alternatively, strip (228) may remain in one piece to cleanly break apart from either grip (224) or body (222). While the present example shows grip (224) pivoting relative to body (222), it should be noted that grip (224) may further be entirely removed from body (222). Once grip (224) pivots away from body (222), a battery (264) is then exposed through an opening (218) on the top portion of grip (224). Grip (224) is then grasped and tipped downwardly to remove battery (264) from grip (224) through opening (218) by allowing battery (264) to slide out of grip (224) under the influence of gravity. Accordingly, grip (224) of handle assembly (220) may be used to dispose of battery (264) such that the user does not directly contact battery (264). Grip (224) may be used to dispose of battery (264) within a battery reclamation bin. Alternatively, battery (264) may be disposed of in any other suitable fashion.

C. Exemplary Peeling Strip Assembly

FIGS. 5A-5C show another exemplary handle assembly (320) that is similar to handle assembly (120), except that handle assembly (320) comprises a strip (327) positioned between body (322) and grip (324). Strip (327) comprises a tab (328). As shown in FIG. 5A, tab (328) is positioned on an end portion of strip (327) and has a larger width than strip (327). In the present example, strip (327) wraps around handle assembly (320) such that the other end of strip (327) contacts tab (328). Strip (327) thereby couples body (322) with grip (324), as shown in FIG. 5A. When strip (327) is secured with body (322) and grip (324), strip (327) provides a fluid tight seal between body (322) and grip (324) such that strip (327) prevents fluids from entering handle assembly (320) at strip (327). When a surgical procedure is finished, a user may grasp tab (328) of strip (327) to pull tab (328) away from handle assembly (320), as shown in FIG. 5B. Tab (328) is pulled to thereby pull strip (327) away from handle assembly (320) to separate strip (327) from body (322) and grip (324). As strip (327) is pulled away, grip (324) is separated from body (222) and battery (364) is exposed through an opening (318) in grip (324), as shown in FIG. 5C. Strip (327) may be fully removed from handle assembly (320) or strip (327) may be partially removed from handle assembly (320) to expose battery (364). Grip (324) is then grasped and tipped downwardly to remove battery (364) from grip (324) through opening (318) by allowing battery (364) to slide out of grip (324) under the influence of gravity. Accordingly, grip (324) of handle assembly (320) may be used to dispose of battery (364) such that the user does not directly contact battery (364). Grip (324) may be used to dispose of battery (364) within a battery reclamation bin. Alternatively, battery (364) may be disposed of in any other suitable fashion.

Although strip assemblies (125, 228, 327) have been described for a handle assembly (20, 120, 220, 320) of an ultrasonic device, such as instrument (10), it should be noted that the exemplary strip assemblies (125, 228, 327) could also be incorporated into other handle assemblies that comprise a battery (64, 164, 264, 364). For example, strip assemblies (125, 228, 327) may be added to handle assemblies of RF electrosurgical devices, surgical stapling devices, and/or other suitable surgical instruments.
