[0003] This disclosure relates to ultrasonic surgical instruments, and more specifically, to apparatus, systems, and methods for manufacturing fluid-cooled ultrasonic surgical instruments. Background Technology

[0004] Ultrasonic surgical instruments and systems utilize ultrasonic energy, i.e., mechanical vibration energy transmitted at ultrasonic frequencies, to process, for example, sealing and / or transecting tissue. Ultrasonic surgical instruments typically include: a waveguide having a transducer coupled to a proximal portion of the waveguide; and an end effector disposed at a distal portion of the waveguide. The waveguide transmits the ultrasonic energy generated by the transducer to the end effector for tissue processing at the end effector. The end effector may include blades, hooks, balls, and / or other features, such as clamping mechanisms for abutting against the end effector to hold tissue and / or facilitate tissue manipulation. During use, the waveguide and / or end effector of the ultrasonic surgical instrument can reach temperatures greater than 200°C or even 300°C. Summary of the Invention

[0005] As used herein, the term "distal" refers to the portion described as being farther from the operator (whether a human surgeon or a surgical robot), while the term "proximal" refers to the portion described as being closer to the operator. As used herein, terms including "corpuscularly," "approximately," "substantially," etc., are intended to cover variations, such as manufacturing tolerances, material tolerances, usage and environmental tolerances, measurement variations, and / or other variations, up to and including ±10%. Furthermore, to a consistent degree, any or all aspects described herein may be used in conjunction with any or all other aspects described herein.

[0006] According to an aspect of this disclosure, an ultrasonic surgical system is provided, comprising an ultrasonic waveguide body defining first and second longitudinal lumens extending through at least a portion of the length of the ultrasonic waveguide body. A distal transverse lumen is defined within the ultrasonic waveguide body, extending laterally through at least a portion of the ultrasonic waveguide body to intersect and interconnect with the first and second longitudinal lumens. A first proximal transverse lumen extends laterally from a first proximal transverse aperture within the ultrasonic waveguide body through a portion of the ultrasonic waveguide body to intersect with the first longitudinal lumen. A second proximal transverse lumen extends laterally from a second proximal transverse aperture within the ultrasonic waveguide body through a portion of the ultrasonic waveguide body to intersect with the second longitudinal lumen. An inflow conduit and an outflow conduit are fluidly connected to the first and second proximal transverse apertures, respectively, to allow fluid to flow into the first longitudinal lumen and out of the second longitudinal lumen, respectively.

[0007] In one aspect of this disclosure, a distal transverse lumen extends from a distal transverse orifice, and a distal transverse orifice plug closes the distal transverse orifice to prevent fluid from flowing out therefrom.

[0008] In one aspect of this disclosure, first and second longitudinal lumens extend proximally from first and second distal faces defined within the distal face of an ultrasonic conductor body. In these aspects, at least one distal face plug closes the first and second distal faces to prevent fluid from flowing out therefrom.

[0009] In another aspect of this disclosure, the first and second proximal transverse holes are defined on opposite sides of the ultrasonic waveguide body. Alternatively, the first and second proximal transverse holes may be defined on the same side of the ultrasonic waveguide body.

[0010] In another aspect of this disclosure, first and second proximal transverse orifice plugs form seals between the inflow and outflow conduits and the first and second proximal transverse orifices, respectively.

[0011] In another aspect of this disclosure, the ultrasonic surgical system also includes a proximal waveguide body adapted for connection to an ultrasonic transducer. In these aspects, the ultrasonic waveguide body is a distal waveguide body including a blade and extending distally from the proximal waveguide body. The distal waveguide body can be releasably engaged with or permanently fixed to the proximal waveguide body (or formed therewith). In providing such engagement, the engagement of the proximal and distal waveguide bodies can close the proximal ends of the first and second longitudinal lumens.

[0012] In another aspect of this disclosure, the waveguide body includes a base and a blade extending distally from the base. The blade may define opposing narrow surfaces and opposing wide surfaces. At least a portion of the distal lateral cavity may be disposed within 10% of the blade length distal to the blade end.

[0013] In another aspect of this disclosure, the ultrasound surgical system also includes a cooling system configured to pump cooling fluid through an inflow conduit into a first longitudinal lumen and / or pump cooling fluid through a second longitudinal lumen into an outflow conduit.

[0014] In another aspect of this disclosure, the ultrasonic surgical system also includes a housing supporting the cooling system and an elongated assembly extending distally from the housing. The elongated assembly includes an ultrasonic waveguide body.

[0015] In another aspect of this disclosure, the housing also supports an ultrasonic transducer configured to generate ultrasonic energy for transmission along an ultrasonic waveguide body. The housing may further support an ultrasonic generator configured to generate an ultrasonic drive signal for driving the ultrasonic transducer, and / or a battery configured to power the ultrasonic generator.

[0016] In another aspect of this disclosure, the distal transverse cavity is formed at least partially via a distal cap that defines the distal tip of the distal waveguide body.

[0017] A method for manufacturing an ultrasonic surgical system according to the present disclosure includes forming first and second longitudinal lumens extending through at least a portion of the length of an ultrasonic waveguide body, forming a distal transverse lumen extending laterally through at least a portion of the ultrasonic waveguide body to intersect and interconnect with the first and second longitudinal lumens, forming first and second proximal transverse lumens extending laterally through a portion of the ultrasonic waveguide body to intersect with the first and second longitudinal lumens respectively, blocking holes formed by the formation of the first and second longitudinal lumens, and blocking holes formed by the formation of the distal transverse lumen.

[0018] In one aspect of this disclosure, the method further includes fluidly connecting an inflow conduit to a first proximal transverse orifice and / or fluidly connecting an outflow conduit to a second proximal transverse orifice.

[0019] In another aspect of this disclosure, the method further includes attaching an ultrasonic waveguide body, serving as the distal waveguide body, to the proximal waveguide body. This attachment can close the proximal ends of the first and second longitudinal lumens. The distal waveguide body can be attached to the proximal waveguide body by inertial friction welding or any other suitable method.

[0020] In another aspect of this disclosure, the method further includes connecting the first and second proximal transverse lumens to inflow and outflow conduits associated with the cooling system, respectively.

[0021] In another aspect of this disclosure, forming a distal transverse lumen includes securing a cap to the distal end of an ultrasonic conductor body to define a distal tip of the ultrasonic conductor body. Attached Figure Description

[0033] Turning Figure 1 and Figure 2The ultrasonic surgical instruments provided according to various aspects of this disclosure are generally identified by reference numeral 10. Instrument 10 is a completely wireless instrument that includes an onboard cooling system in addition to an onboard power supply (e.g., a battery) and an ultrasound generator and transducer. However, it is also contemplated that instrument 10 be configured as a wired instrument, for example, wherein instrument 10 is configured to be connected to a remote cooling system via one or more fluid lines and to a remote ultrasound generator (separately or integrated with the remote cooling system) via a cable; or as a partially wired instrument, for example, wherein instrument 10 includes an onboard power supply and an ultrasound generator and is configured to be connected to a remote cooling system via one or more fluid lines, or wherein instrument 10 includes an onboard cooling system and is configured to be connected to a remote ultrasound generator. Similarly, other types of ultrasonic instruments are also contemplated, such as pencil-type instruments, hemostat-type instruments, etc. Therefore, although specific aspects and features of instrument 10 are detailed below, it should be understood that the aspects and features of this disclosure are equally applicable to any other suitable ultrasonic surgical instrument or system, such as robotic surgical system 1000. Figure 3 For example, other suitable apparatuses used according to this disclosure, including remote or airborne cooling systems, are described in the following patent application publications: US 2019 / 0247073, filed February 13, 2018, entitled “REMOVABLE FLUID RESERVOIR AND ULTRASONIC SURGICAL INSTRUMENT INCLUDING THE SAME”; and US 2017 / 0281215, filed March 18, 2017, entitled “DEVICES, SYSTEMS, AND METHODS FOR COOLING ASURGICAL INSTRUMENT”, the entire contents of each of them are incorporated herein by reference.

[0034] The device 10 typically includes a handle assembly 100, an elongated component 200 extending distally from the handle assembly 100, a transducer and generator assembly (“TAG”) 300 configured to be releasably engaged with the handle assembly 100, and a battery 400 configured to be removably received in the handle assembly 100. The elongated component 200 may be integral with the handle assembly 100 or may be releasably engaged with the handle assembly 100.

[0035] The handle assembly 100 includes a housing 110, a cooling system 120, a switch assembly 140, a generator base 150, a battery base 160, a flexible circuit assembly 170 (including flexible circuit portions 182 and 184), and a clip trigger 190.

[0036] The housing 110 of the handle assembly 100 defines a body portion 112 and a fixed handle portion 114. The body portion defines a longitudinal axis, and the fixed handle portion extends from the body portion 112 at an angle relative to the longitudinal axis of the body portion 112 (although the fixed handle portion 114 may alternatively extend perpendicularly relative to the longitudinal axis of the body portion 112). The body portion 112 of the housing 110 is configured to receive a proximal portion of an elongated assembly 200, which is operatively engaged with a clip-on trigger 190 such that actuation of the clip-on trigger 190 actuates the end effector assembly 280 of the elongated assembly 200. When engaged with the body portion 112 of the housing 110, the elongated assembly 200 is aligned along the longitudinal axis of the body portion 112. The main body portion 112 of the housing 110 is also configured to support the TAG 300 thereon, wherein the transducer 320 of the TAG 300 is mechanically coupled to the waveguide 230 of the elongated assembly 200, for example, by threaded connection, latch, or any other suitable means, and both are aligned on the longitudinal axis of the main body portion 112 of the housing 110. When the TAG 300 is engaged with the main body portion 112 of the housing 110, the generator 340 of the TAG 300 is electrically connected to the generator mount 150 of the housing 110. The fixed handle portion 114 of the housing 110 defines an internal compartment 116, which is configured to removably receive the battery 400 therein, and a hinged door 118 is configured to enclose the battery 400 within the internal compartment 116.

[0037] Cooling system 120 includes one or more fluid pumps 122 and, in some respects, a fluid reservoir 124, although the fluid reservoir 124 may be omitted in other configurations. Cooling system 120 also includes associated conduits 126 operably interconnecting the fluid pumps 122, the fluid reservoir 124, and inflow and return conduits 128a, 128b (or, in the case where the fluid reservoir 124 is omitted, interconnected fluid pumps 122 and inflow and return conduits 128a, 128b) for pumping cooling fluid to and from the elongated assembly 200. The inflow and return conduits 128a, 128b may extend along and / or through the elongated assembly 200, ultimately entering its waveguide 230 to allow cooling fluid circulation through the blades 282 of the end effector assembly 280 of the elongated assembly 200, as described in more detail below.

[0038] One or more fluid pumps 122 of the cooling system 120 are supported within the main body portion 112 of the housing 110. For example, the fluid pumps 122 may be supported on either side or both sides of the main body portion 112 of the housing 110 at locations radially spaced apart from the longitudinal axis of the main body portion 112 of the housing 110. In such a configuration, the fluid pumps 122 may define a relatively thin, elongated structure such that sufficient space is defined between the plurality of pumps 122 and / or between the pumps 122 and the housing 110 to allow the transducer 320 of the TAG 300 to pass between them (aligned on the longitudinal axis), while requiring a minimum (if any) increase in the overall size of the main body portion 112 of the housing 110 to accommodate the pumps 122.

[0039] The connection interface 130 of the cooling system 120, which enables the transmission of electrical and / or control signals to the pump 122, is positioned to not interfere with the TAG 300. Furthermore, a connector 132, such as a lead, cable, flexible circuit, or other suitable connector, extends through the body portion 112 of the housing 110 to connect the connection interface 130 to the flexible circuit assembly 170 of the handle assembly 100 to allow the transmission of electrical and control signals between the pump 122, the generator 340, the switching assembly 140, and / or the battery 400. More specifically, the pump of the cooling system 120 can be controlled via, for example, a controller of the generator 340 within a control box, the battery 400, or a separate controller for the cooling system 120. Regardless of location and / or configuration, the controller is configured to control the pump 122 to maintain a cooling fluid flow sufficient to cool the blade 282 of the end effector 280, to enable and disable cooling in response to manual input, and / or to achieve automatic cooling (e.g., when the energy source is deactivated). One or more fluid pumps 122 may be piezoelectric microfluidic pumps or other microfluidic pumps, such as micro-peristaltic pumps, syringe pumps, etc. Regardless of the specific pump configuration used, one or more fluid pumps 122 may be configured in various respects to generate a sufficient flow rate of cooling fluid to cool the waveguide 230 of the elongated component 200 from an initial temperature of about 300°C to about 100°C (or about 120°C) to a cooling temperature of about 70°C to about 0°C (or below about 60°C) within about 0.5 seconds to about 2.5 seconds (or less than about 2 seconds). However, other temperatures and / or cooling times may also be considered.

[0040] Continue to refer to Figure 1 and Figure 2A fluid reservoir 124 is disposed within the housing 110 of the handle assembly 100. More specifically, the fluid reservoir 124 is disposed within the fixed handle portion 114 of the housing 110 and positioned between the internal compartment 116 of the fixed handle portion 114 and the main body portion 112 of the housing 110. The fluid reservoir 124 may define a cutout 134 within which at least a portion of the clip-on trigger 190 extends when actuated. Thus, the fluid reservoir 124 does not interfere with the actuation of the clip-on trigger 190. It is also contemplated that the fluid reservoir 124 is located in other positions, such as at the free end of the fixed handle portion 114, such that the battery 400 is disposed between the fluid reservoir 124 and the main body portion 112.

[0041] The fluid reservoir 124 also includes a port 136 having an inlet 137a and an outlet 137b. A conduit 126 of the cooling system 120 connects to the inlet 137a and outlet 137b of the fluid reservoir 124 to connect the fluid reservoir 124 to the fluid pump 122 and inflow and return conduits 128a, 128b. More specifically, one or both ends 138a, 138b of the conduit 126 may extend through the inlet 137a and outlet 137b and into the fluid reservoir 124, such that the ends 138a, 138b of the conduit 126 are positioned on opposite sides, ends, or portions of the fluid reservoir 124, thereby maximizing the spacing between them. This configuration prevents hotter, returning cooling fluid from being immediately pumped back from the fluid reservoir 124. Furthermore, the ends 138a and 138b of the conduit 126 are positioned relative to each other within the fluid reservoir 124, such that any air in the fluid reservoir 124 is prevented from entering the inflow conduit 128a regardless of the orientation of the handle assembly 100.

[0042] The switch assembly 140 of the handle assembly 100 includes an energy-activated button 142 operatively positioned to be electrically coupled to a flexible circuit assembly 170. The flexible circuit assembly 170 electrically couples the switch assembly 140, the battery 400, and the TAG 300 to each other. Therefore, when the energy-activated button 142 is activated in an appropriate manner, power is supplied from the battery 400 to the TAG 300. The energy-activated button 142 can be configured for dual-mode activation, such that a first activation of the energy-activated button 142 drives the TAG 300 in a “low” power mode, while a second, different activation of the energy-activated button 142 drives the TAG 300 in a “high” power mode. Other suitable activation configurations are also considered.

[0043] In some aspects, the switch assembly 140 of the handle assembly 100 also includes a pair of cooling start buttons 144 operably positioned on either side of the housing 110. A flexible circuit assembly 170 electrically couples the connection interface 130 of the cooling system 120 to the switch assembly 140, the battery 400, and the TAG 300. Therefore, activation of one or both of the cooling start buttons 144 initiates cooling. In some aspects, multiple activations and / or specific activation modes of the cooling start buttons 144 can subsequently terminate cooling, switch between different cooling modes or programs, etc.

[0044] A generator holder 150 is disposed on the main body portion 112 of the housing 110 and positioned to be electrically coupled to the generator 340 of the TAG 300 when the TAG 300 is engaged with the housing 110. A battery holder 160 is disposed within an internal compartment 116 of the fixed handle portion 114 of the housing 110 and positioned to be electrically coupled to the battery 400 when receiving the battery 400 within the internal compartment 116. Connectors 132 of the holders 150, 160, the flexible circuit assembly 170 (including its flexible circuit portions 182, 184), and the cooling system 120 electrically couple the TAG 300, the switch assembly 140, the control box of the cooling system 120, and the battery 400 to each other to enable the transmission of power and / or control signals between them. More specifically, the flexible circuit portion 182 interconnects the battery holder 160 with the flexible circuit assembly 170. The flexible configuration of the flexible circuit section 182 allows the flexible circuit 182 to be wired around the fluid reservoir 124, which is arranged between the flexible circuit assembly 170 and the battery holder 160. On the other hand, the flexible circuit section 184 electrically couples the flexible circuit assembly 170 to the generator holder 150.

[0045] Still referencing Figure 1 and Figure 2 The clamp trigger 190 of the handle assembly 100 of the instrument 10 extends from the body portion 112 of the housing 110 in a relative relationship to the fixed handle portion 114 of the housing 110. The clamp trigger 190 is pivotally coupled to the body portion 112 of the housing 110 and operatively associated with the elongated assembly 200 such that pivoting of the clamp trigger 190 toward the fixed handle portion 114 of the housing 110 causes the jaws 284 of the end effector assembly 280 of the elongated assembly 200 to pivot from an open position to a clamping position for clamping tissue between the jaws 284 and the blade 282, which extends distally from the waveguide 230 of the elongated assembly 200.

[0046] The elongated assembly 200 typically includes a sleeve assembly having an outer sleeve 210 and an inner sleeve (not shown) disposed within the outer sleeve 210, a waveguide 230 extending through the inner sleeve (not shown), a drive assembly 250, a rotation assembly 270 operably arranged around the outer sleeve 210, and an end effector assembly 280 arranged at the distal end of the sleeve assembly. As described above, the end effector assembly 280 includes a blade 282 and a jaw 284 operably coupled to the outer sleeve 210 such that translation of the outer sleeve 210 causes the jaw 284 to pivot relative to the blade 282 between an open position and a clamped position. The drive assembly 250 operably couples a proximal portion of the outer sleeve 210 to a clamp trigger 190 such that actuation of the clamp trigger 190 causes the jaw 284 to pivot relative to the blade 282 between an open position and a clamped position. In the detailed configuration described above, the inner sleeve is the support sleeve, while the outer sleeve is the drive sleeve, although the opposite configuration could also be considered, as could other suitable drive mechanisms for pivoting the jaws 284 relative to the blade 282.

[0047] The jaws 284 of the end effector assembly 280 include a more rigid structural body 285a and a more compliant jaw liner 285b. The structural body 285a is pivotally coupled to the inner sleeve of the elongated assembly 200 and operably coupled to the outer sleeve 210 of the elongated assembly 200 such that the aforementioned detailed translation of the outer sleeve 210 allows the jaws 284 to pivot relative to the blade 282 to clamp tissue between the jaw liner 285b and the blade 282. The jaw liner 285b is positioned opposite the blade 282 in the clamped position of the jaws 284.

[0048] Waveguide 230 extends through an inner sleeve (not shown), includes a blade 282 extending from its distal end, and includes a proximal portion configured to be operatively coupled to transducer 320, for example, by threaded connection, latching, or any other suitable means. In various respects, inflow and return conduits 128a, 128b may extend at least partially from housing 110 along and / or through elongated assembly 200 and then be fluidly coupled to, or may be fluidly coupled to, the waveguide 230 within housing 110. The waveguide 230, the internal flow path defined within the waveguide 230, and the coupling of inflow and return conduits 128a, 128b to the waveguide 230 are described in more detail below.

[0049] Both the TAG 300 and the battery 400 are detachable from the handle assembly 100 for disposal or sterilization. The TAG 300 can be configured to withstand sterilization, allowing it to be sterilized for reuse. Conversely, the battery 400 is configured for aseptic transfer and retention within the compartment 116 of the retaining handle portion 114 of the housing 110 of the handle assembly 100, enabling it to be reused without sterilization. Alternatively or additionally, the battery 400 can be sterilized. In some configurations, the TAG 300 (or a portion thereof, such as the generator 340 or transducer 320) can be integrated with the housing 110.

[0050] TAG 300 includes an ultrasonic transducer 320 and a generator 340. A set of connectors 362 and corresponding rotary contacts 364 associated with the generator 340 and ultrasonic transducer 320, respectively, enable the transmission of data and drive signals from the generator 340 to the transducer 320, such as the piezoelectric element of the transducer 320, to drive the transducer 320. A battery 400 powers the generator 340 to generate drive signals, such as a high-voltage AC signal, transmitted to the transducer 320. The transducer 320 converts the signals into mechanical motion, which is output along waveguide 230 to the blade 282 of the end effector assembly 280. The transducer 320 further includes a knob 380 located at its proximal end to allow the transducer 320 to rotate relative to the generator 340 and the handle assembly 100. Rotating the knob 380 also facilitates operable connection of the transducer 320 to the elongated assembly 200.

[0051] refer to Figure 3 The robotic surgical system according to the aspects and features of this disclosure is generally identified by reference numeral 1000. For the purposes of this document, the robotic surgical system 1000 is generally described. Aspects and features of the robotic surgical system 1000 that are not closely related to the understanding of this disclosure are omitted so as not to obscure the aspects and features of this disclosure with unnecessary detail.

[0052] A robotic surgical system 1000 typically includes: multiple robotic arms 1002, 1003; a control unit 1004; and an operation console 1005 connected to the control unit 1004. The operation console 1005 may include a display device 1006, which may be specifically configured to display three-dimensional images; and manual input devices 1007, 1008, through which the surgeon can remotely manipulate the robotic arms 1002, 1003 in a first operating mode. The robotic surgical system 1000 may be configured for minimally invasive use on a patient 1013 lying on a patient table 1012. The robotic surgical system 1000 may further include a database 1014 specifically connected to the control unit 1004, containing, for example, preoperative data stored from the patient 1013 and / or anatomical atlases.

[0053] Each of the robotic arms 1002 and 1003 may include multiple components connected by joints, and attachment devices 1009 and 1011, such as surgical instruments "ST" supporting end effectors 1050 and 1060, which may be attached to these attachment devices. One of the surgical instruments "ST" may be an ultrasonic surgical instrument 10 ( Figure 1 In this configuration, manual operation and actuation features are replaced by robotic input. In such a configuration, the robotic surgical system 1000 may include or be configured to connect to an ultrasound generator, power supply, and cooling system. Other surgical instruments “ST” may include any other suitable surgical instruments, such as an endoscopic camera, other surgical tools, etc. The robotic arms 1002, 1003 may be driven by electrical actuators, such as motors, connected to a control unit 1004. The control unit 1004 (e.g., a computer) may be configured to actuate the motors in a manner specifically through a computer program that causes the robotic arms 1002, 1003, their attachments 1009, 1011, and thus the surgical instruments “ST” to perform desired movements and / or functions, respectively, based on corresponding inputs from manual input devices 1007, 1008. The control unit 1004 may also be configured to regulate the movement of the robotic arms 1002, 1003 and / or the motors.

[0054] refer to Figure 1 , 2 As described above, waveguide 230 includes a blade 282 disposed at its distal end. More specifically, waveguide 230 includes a proximal body 232. Figure 2 and 4A ) and the distal body 234 including the blade 282 ( Figure 4A and 4BIn various respects, the proximal body 232 and the distal body 234 may be integrally formed from a single piece of material or may be formed separately and subsequently attached to each other (permanently or removably). The proximal body 232 and the distal body 234 may be attached via a threaded engagement, for example, by means of a threaded plug 233 of the proximal body 232. Figure 4A ) Receives a threaded hole 236 defined within the proximal end of the distal body 234. Figure 4A and 4B Within. Other attachment methods are also considered, such as various types of welding (e.g., inertial friction welding), brazing, brazing, diffusion bonding, etc. The proximal body 232 and / or the distal body 234 may be formed of aluminum, aluminum alloy, titanium, titanium alloy, or other suitable similar or dissimilar materials.

[0055] The proximal body 232 of waveguide 230 extends from the housing 110 through at least a portion of the inner support sleeve of elongated assembly 200 to the distal body 234. The proximal body 232 is configured to operatively engage the ultrasonic transducer 320 such that ultrasonic motion generated by the ultrasonic transducer 320 is transmitted along the proximal body 232 to the distal body 234 and ultimately to the blade 282 for treating tissue clamped between or located near the blade 282 and jaws 284. The proximal body 232 may define a generally cylindrical structure and may be solid, but hollow or semi-hollow constructions are also contemplated.

[0056] For details, please refer to the following: Figure 4A and 4B The distal body 234 includes a base 238 and a blade 282 extending distally from the base 238. The base 238 and the blade 282 may be integrally formed from a single piece of material or may be formed separately and subsequently attached to each other (permanently or removably). The base 238 defines a generally cylindrical construction, but other constructions are also contemplated. The blade 282 extends distally from the base 238. The blade 282 may define a substantially linear construction (as shown), may define a curved construction, or may define any other suitable construction, such as straight and / or curved surfaces, portions and / or sections; one or more convex and / or concave surfaces, portions and / or sections; etc. Regarding curved constructions, the blade 282, more specifically, may be relative to the jaw 284 ( Figure 1 ) bends in any direction, for example, such that the distal tip of the blade 282 faces the jaws 284 ( Figure 1 ) Bend away from the jaws 284 ( Figure 1 ) bent, or relative to jaws 284 ( Figure 1(In any direction) laterally curved. Furthermore, the blade 282 can be formed to include multiple curves in similar directions, multiple curves in different directions within a single plane, and / or multiple curves in different directions within different planes. Furthermore, while one configuration of the blade 282 is described and illustrated herein, it is contemplated that the blade 282 may additionally or alternatively be formed to include any suitable features, such as a tapered configuration, various different cross-sectional configurations along its length, cuts, notches, edges, protrusions, straight surfaces, curved surfaces, angled surfaces, wide edges, narrow edges, and / or other features. In some aspects, the blade 282 defines a pair of relatively narrow, generally convex opposing surfaces and a pair of relatively wide, generally flat opposing surfaces, but other configurations are also contemplated. One of the narrow surfaces may be positioned relative to the jaws 284 ( Figure 1 In contrast, one of the wide surfaces can be positioned relative to jaw 284 ( Figure 1 ) Relative, or blade 282 and / or jaws 284 ( Figure 1 ) can be rotated relative to each other to position with jaws 284 ( Figure 1 The desired surface is relative to the base 238. A transition region 240 that defines a gradual (or more gradual) transition between the base 238 and the blade 282 may also be provided.

[0057] The distal body 234 may be formed of a solid material in which various lumens, detailed below, are formed, but other configurations are also contemplated. More specifically, the distal body 234 includes first and second longitudinal lumens 242, 244, which extend relative to each other in a substantially parallel, spaced-apart relationship via at least a portion of the base 238 and the blade 282. The longitudinal lumens 242, 244 communicate with distal holes 243, 245, respectively, defined by the distal side of the blade 282. The longitudinal lumens 242, 244 may be formed within the distal body 234 during the manufacture of the distal body 234 (e.g., as part of an extrusion process or other suitable forming process) or may be formed after the manufacture of the distal body 234 (e.g., by drilling). In either configuration, the longitudinal lumens 242, 244 extend proximally through the distal side of the blade 282, through at least a portion of the blade 282 and the base 238 to a closed or open proximal end. Alternatively, in a configuration where the distal body 234 can be removed from the proximal body 232 ( Figure 4A The longitudinal lumens 242, 244 can be formed within the distal body 234 through the proximal portion of the base 238 (or waveguide 230), reaching or passing through the distal end face of the blade 282. In some aspects, the threaded hole 236 of the base 238 communicates with the open proximal end of the longitudinal lumens 242, 244. In these aspects, the threaded plug 233 of the proximal body 232 (see...) Figure 4AThe threaded engagement within the threaded hole 236 of the base 238 of the distal body 234 to attach the proximal body 232 and the distal body 234 to each other also serves to seal the proximal ends of the longitudinal lumens 242, 244 (either self-sealing or using seals such as grommets, O-rings, gaskets, sealants, overmolded parts, etc., positioned between the proximal and distal bodies 232, 234, for example, pressed distally to bottom out within the threaded hole 236). In other configurations, the longitudinal lumens 242, 244 communicate with one or more internal lumens (e.g., individual lumens or dedicated lumens corresponding to each longitudinal lumen 242, 244), which are defined within the proximal body 232 and extend at least partially through it to reach the closed or closable proximal end of the internal lumen of the proximal body 232. In some respects, this internal cavity of the proximal body 232 extends to the proximal end of the proximal body 232 and is connected to the transducer 320 via the proximal body 232 of the waveguide 230. Figure 2 They are sealed by their joints (either by themselves or with a seal), for example, by the threaded joint between them.

[0058] Continue to refer to Figure 4A and 4B The distal transverse lumen 246 is defined at least partially through the distal portion of the blade 282, for example, within approximately 15% of the length of the blade 282 from its distal end, in other respects within approximately 10%, and in other respects within approximately 5%. The distal transverse lumen 246 can be formed within the blade 282 by drilling, for example, forming a distal transverse hole 247 disposed on one side of the blade 282, or in any other suitable manner. The distal transverse lumen 246 extends laterally through one of the longitudinal lumens 242, 244 and communicates with the other longitudinal lumen 242, 244. In this way, the distal transverse lumen 246 establishes communication between the longitudinal lumens 242, 244 within the distal portion of the blade 282. The distal transverse lumen 246 may not extend completely through the blade 282, for example, thus forming a single distal transverse hole 247, or it may extend completely through it, for example, such that a pair of opposing distal transverse holes 247 are formed. The distal transverse lumen 246 may extend at a substantially perpendicular orientation relative to the longitudinal lumens 242 and 244 or at a certain angle relative to the longitudinal lumen.

[0059] The base 238 of the distal body 234 of waveguide 230 defines a pair of proximal transverse cavities 248a, 248b passing through it, although it is also contemplated that the proximal transverse cavities 248a, 248b are defined within the proximal body 232 of waveguide 230 (in a configuration in which the longitudinal cavities 242, 244 communicate with a corresponding cavity defined through at least a portion of the proximal body 232). The proximal transverse cavities 248a, 248b extend from transverse apertures 249a, 249b on opposite sides of the base 238 to communicate with the longitudinal cavities 242, 244, respectively, or may be located on the same side of the base 238 and extend to communicate with the corresponding longitudinal cavities 242, 244. The longitudinal cavities 242, 244 may terminate at or extend proximally beyond the proximal transverse cavities 248a, 248b. Proximal lateral lumens 248a, 248b may be formed by drilling through the base 238 or by any other suitable means. The proximal lateral lumens 248a, 248b may extend only partially through the base 238 to maintain isolation between the longitudinal lumens 242, 244 within the base 238, or they may extend completely through the base 238, thereby sealing off any undesirable holes formed during manufacturing, for example, according to any aspect detailed herein. Whether formed initially or sealed off subsequently, the proximal lateral lumens 248a, 248b communicate with one of the longitudinal lumens 242, 244, but not with the other longitudinal lumen 242, 244. The proximal lateral lumens 248a, 248b may be laterally aligned with each other or longitudinally offset relative to each other, and one or both may extend substantially perpendicularly to the longitudinal lumens 242, 244 or at an angle relative to the longitudinal lumens.

[0060] Also refer to Figure 5 During manufacturing, in order to limit the flow from cooling system 120, through waveguide 230 and back to cooling system 120 (see...) Figure 2The closed fluid loop, which fluidly connects the inflow and return conduits 128a and 128b to the longitudinal lumens 242 and 244 respectively and passes through various orifices 243, 245, 247, 249a, and 249b defined by the waveguide 230, is sealed to prevent fluid from escaping from the closed fluid loop. Although the fluid loop from the cooling system 120 through the waveguide 230 and back to the cooling system 120 is closed, the cooling system 120 itself may define an open-loop configuration (e.g., where the supply fluid and return fluid are separate and the return fluid is not recirculated), a closed-loop configuration (e.g., where the return fluid is recirculated as the supply fluid), or a semi-closed-loop configuration (e.g., where some of the return fluid is recirculated while others are not). Furthermore, in other configurations, one or more holes 243, 245, 247, 249a, 249b defined through waveguide 230 are sealed closed, while one or more other holes 243, 245, 247, 249a, 249b defined through waveguide 230 remain open to control the direction of fluid from waveguide 230 in one or more specific ways in an open-loop system, for example, as a suction device and / or a suction device.

[0061] Inflow and return conduits 128a, 128b may extend to or at least partially through transverse orifices 249a, 249b, such that inflow fluid can be delivered through proximal transverse orifice 249a, proximal transverse lumen 248a and into longitudinal lumen 242, from longitudinal lumen 242 to longitudinal lumen 244 via distal transverse lumen 246 at the distal portion of blade 282, and such that return fluid from longitudinal lumen 244 can return to return conduit 128b through proximal transverse lumen 248b and transverse orifice 249b. Inflow conduit 128a and / or return conduit 128b may be oriented substantially perpendicular to longitudinal lumen 242, 244, respectively, inside and / or outside of waveguide 230, or may be angled relative to longitudinal lumen 242, 244. Additionally or alternatively, as described above, proximal transverse lumen 248a, 248b may be angled or substantially perpendicular to longitudinal lumen 242, 244. By angulating the inflow conduit 128a and / or the return conduit 128b and / or angulating one or both of the proximal transverse lumens 248a, for example, by angulation proximally, fluid inflow and outflow from the longitudinal lumens 242, 244 can be facilitated, but other configurations are also considered. In configurations where the inflow and return conduits 128a, 128b extend at least partially into the proximal transverse lumens 248a, 248b, the ends of the inflow and return conduits 128a, 128b can be cut at an angle, obliquely, or otherwise asymmetrically configured to facilitate fluid flow in a desired manner, for example, from the inflow conduit 128a distally through the longitudinal lumen 242 and / or proximally through the longitudinal lumen 244 into the return conduit 128b.

[0062] Still referencing Figure 4A-5 Holes 243, 245, 247, 249a, and 249b can be closed by corresponding plugs 260. Plugs 260 may be similar to or different from each other, and may seal holes 243, 245, 247, 249a, and 249b in similar or different ways. One or more of the plugs 260 may be configured as, for example, rods, such as titanium rods or other rods made of materials similar to or different from the distal body 234 of waveguide 230, which are inserted into and welded therein to seal holes 243, 245, 247, 249a, and 249b. In these respects, lost-wax fixing, depth gauges, or other suitable fixings may be used to hold the rods in place during welding. In some respects, one or more plugs 260 may be formed of, for example, a high-temperature polymer, rubber, or metal, and in these or other respects may be welded, thermally interfered with, brazed (where the plug is formed entirely of welding material or where plugs of different materials are welded), brazed, or otherwise fixed in the appropriate position within the respective holes 243, 245, 247, 249a, 249b to sealably close the respective holes 243, 245, 247, 249a, 249b.

[0063] In all respects, plugs 260 configured to hermetically close orifices 243, 245 can be connected via connectors such that plugs 260 are inserted together into and secured in the corresponding orifices 243, 245 (in any manner detailed herein or any other suitable manner, and plugs 260 are formed of any suitable material, such as any of those materials detailed herein). Such plugs 260 may define a substantially U-shaped configuration and be inserted from the outside of waveguide 230. Alternatively, such plugs 260 may comprise O-rings (either on their own or together with plug portions extending therefrom) or other sealing connectors, such as gaskets, which are inserted distally through lumens 242, 244 to seal closed orifices 243, 245 (and, in some respects, orifice 247).

[0064] One or more plugs 260 may be overmolded from the inside or outside of the corresponding holes 243, 245, 247, 249a, 249b to seal the corresponding holes 243, 245, 247, 249a, 249b. One or more of the plugs 260 may be formed individually and then inserted (from the inside or outside) and sealed in the corresponding holes 243, 245, 247, 249a, 249b, or may be formed in the corresponding holes 243, 245, 247, 249a, 249b, for example, by filling the corresponding holes with material from the inside or outside via overmolding, casting, brazing, soldering, etc. One or more of the plugs 260 may be configured to secure screws or other threaded elements and / or one or more of the holes 243, 245, 247, 249a, 249b may include threads to achieve a sealing engagement from the inside or outside of the corresponding holes 243, 245, 247, 249a, 249b through the threads of one or more plugs 260 (either by themselves, for example, by sealing via pipe threads, or by using additional seals or sealing materials).

[0065] In the configuration defining the open proximal ends of the longitudinal lumens 242, 244, the open proximal ends may be plugged together or separately according to any of the aspects detailed above or in any other suitable manner. Furthermore, regarding the plug 260 of the orifices 249a, 249b, the inflow and outflow conduits 128a, 128b may extend through the plug 260, be defined within the plug 260, forming the plug 260, be surrounded by the plug 260, or otherwise configured relative to the plug 260 such that the plug 260 seals the orifices 249a, 249b and the inflow and outflow conduits 128a, 128b respectively to prevent fluid escape from the system while allowing fluid to flow between the waveguide 230 and the inflow and outflow conduits 128a, 128b. Any combination of two or more of the above-described plug configurations is also considered as other configurations to facilitate the sealing closure of some or all of the orifices 243, 245, 247, 249a, 249b.

[0066] General Reference Figure 1-5 In use, after cooling startup, the cooling system 120 is configured to pump fluid from the fluid reservoir 124 using one or more fluid pumps 122, through inflow conduit 128a, proximal transverse lumen 248a, distally through longitudinal lumen 242, via distal transverse lumen 246 at the distal portion of the blade 282 from longitudinal lumen 242 to longitudinal lumen 244, proximally through longitudinal lumen 244, through transverse lumen 248b, through outflow conduit 128b, and back to the fluid reservoir 124. In this way, the cooling fluid circulates substantially entirely along the length of the blade 282 to facilitate cooling of the blade 282. The cooling fluid can be brine, water, or other suitable fluid.

[0067] Go to Figures 6A-6BThis illustrates the distal body 1234 of a blade 1282 including another waveguide 1230 provided according to aspects of this disclosure. Unless explicitly contradicted below, waveguide 1230 may be used with waveguide 230 ( Figure 1 , 2 Any features of waveguides 1230, 4A, and 4B are similarly configured and include any one of their features. Therefore, the following description will focus on waveguides 1230 and 230 ( Figure 1 , 2 The differences between 4A and 4B are not described, while similarities are only described in general terms or omitted entirely.

[0068] The distal body 1234 of waveguide 1230 includes a base 1238 and a blade 1282 extending distally from the base 1238. The distal body 1234 also includes first and second longitudinal lumens 1242, 1244, which extend substantially parallel and spaced apart from each other by at least a portion of the base 1238 and the blade 1282 to open the distal end. A cap 1250 defining connector lumen 1252 is welded, brazed, or otherwise secured to the distal end of the blade 1282, thereby defining the distal tip of the blade 1282. The cap 1250 may be formed of the same material as or a different material from the blade 1282. After the cap 1250 is secured to the distal end of the blade 1282, connector lumen 1252 establishes communication between the open distal ends of the longitudinal lumens 1242, 1244 and otherwise seals the fluid flow path, preventing fluid from escaping from the distal body 1234. Therefore, cooling fluid can be pumped distally through the distal body 1234 via one of the longitudinal cavities 1242, 1244 and can be returned proximally through the distal body 1234 via the connector cavity 1252 and the other longitudinal cavity 1242, 1244, thereby cooling the distal body 1234 of the waveguide 1230. For the distal body 1234, it is not necessary to provide a transverse cavity towards the distal end of the longitudinal cavities 1242, 1244.

[0069] refer to Figure 7 This illustrates a distal body 2234 comprising a blade 2282 including another waveguide 2230 provided according to an aspect of this disclosure. The distal body 2234 is similar to and may include the distal body 1234 ( Figure 6A and 6B Any characteristic of ) unless explicitly contradicted below.

[0070] The distal body 2234 of waveguide 2230 includes a base 2238 and a blade 2282 extending distally from the base 2238. The distal body 2234 also includes a first longitudinal cavity and second longitudinal cavities 2242, 2244, which extend substantially parallel and spaced apart from each other via at least a portion of the base 2238 and the blade 2282. The longitudinal cavities 2242, 2244 terminate in and communicate with a transverse cavity 2246, which is disposed at the distal end of the blade 2282 and communicates with its distal opening. Therefore, cavities 2242, 2244, and 2246 are all in communication with the distal opening of the blade 2282.

[0071] A cap 2250, comprising a base 2252 and a head 2254, is welded, brazed, or otherwise secured to the distal end of the blade 2282, thereby defining the distal tip of the blade 2282, wherein the base 2252 extends at least partially into the distal end of the blade 2282 opening and the head 2254 abuts the distal end face of the blade 2282. After the cap 2250 is secured to the distal end of the blade 2282 in this manner, the distal end of the blade 2282 opening is sealed closed, while a fluid flow path between the longitudinal cavities 2242, 2244 is still maintained through the transverse cavity 2246. Therefore, cooling fluid can be pumped distally through the distal body 2234 via one of the longitudinal cavities 2242, 2244 and can be returned proximally through the distal body 2234 via the transverse cavity 2246 and the other longitudinal cavity 2242, 2244, thereby cooling the distal body 2234 of the waveguide 2230. When the cap 2250 is welded or otherwise attached to the blade 2282, the base 2252 of the cap 2250 facilitates the proper alignment and orientation of the cap 2250 relative to the blade 2282.

[0072] refer to Figure 8A and 8B This illustrates a distal body 3234 comprising a blade 3282 including another waveguide 3230 provided according to an aspect of this disclosure. The distal body 3234 is similar to and may include a distal body 1234 ( Figure 6A and 6B Any characteristic of ) unless explicitly contradicted below.

[0073] This does not provide information as described above regarding the distal subject 1234 (see above). Figure 6A and 6BThe cap 1250, as detailed, includes a distal body 3234 comprising a bend 3250 (bent, angled, and / or otherwise bent) defining a lumen 3252 through which it is secured, for example by welding, brazing, or otherwise, to the distal end of the blade 3282, such that the lumen 3252 establishes communication between the distal ends of the openings of the longitudinal lumens 3242, 3244 and otherwise seals the fluid flow path, preventing fluid from escaping from the distal body 3234. Therefore, cooling fluid can be pumped distally through the distal body 3234 via one of the longitudinal lumens 3242, 3244 and can be returned proximally through the distal body 3234 via lumen 3252 and the other longitudinal lumen 3242, 3244, thereby cooling the distal body 3234 of the waveguide 3230.

[0074] General Reference Figure 6A-8B In some respects, cap 1250, cap 2250 and / or tube 3250 may be defined with features to facilitate tissue handling. For example, cap 1250, cap 2250 and / or tube 3250 may be defined as angular, rounded, curved and / or other suitable configurations to facilitate, for example, ear excision, blunt dissection and / or other surgical tasks with or without the use of ultrasonic energy.

[0075] Go to Figure 9 and 10 This shows the proximal portion of the distal body 4234, 5234 of other waveguides 4230, 5230 provided according to aspects of this disclosure. Unless explicitly contradicted below, waveguides 4230, 5230 may be similar to and include waveguide 230 ( Figure 1 , 2 4A and 4B), any other waveguides detailed herein and / or any other suitable waveguides, and any characteristics thereof. Therefore, the following description will focus on waveguides 4230, 5230 and waveguides described in detail above, such as waveguide 230 (…). Figure 1 , 2 The differences between 4A and 4B are not described, while similarities are only described in general terms or omitted entirely.

[0076] refer to Figure 9The distal body 4234 of waveguide 4230 defines longitudinal lumens 4242, 4244 extending at least partially through it. The longitudinal lumens 4242, 4244 define proximal openings that open into the proximal end of the distal body 4234. The distal body 4234 of waveguide 4230 also includes a connector body 4250, which is secured, for example, by welding, brazing, or otherwise, to the proximal end of the distal body 4234. The connector body 4250 may be formed of the same or different material as the distal body 4234, and when the connector body 4250 is secured to the proximal end of the distal body 4234, a seal closes the proximal ends of the longitudinal lumens 4242, 4244. The connector body 4250 may also include a proximal aperture 4236 such that the proximal body of waveguide 4230 (not shown, see proximal body 232) Figure 4A The proximal body and the distal body 4234 are connected and secured to each other by threads or other suitable engagement within the proximal hole 4236 (via the connector body 4250 therebetween) so that ultrasonic energy can be transmitted along them.

[0077] refer to Figure 10 The distal body 5234 of waveguide 5230 defines longitudinal lumens 5242, 5244 extending at least partially therethrough and a proximal aperture 5236 defined therein at its proximal end. The proximal ends of the longitudinal lumens 5242, 5244 communicate with the proximal aperture 5236. A plug 5250 is secured within the proximal aperture 5236 at the open proximal ends of the longitudinal lumens 5242, 5244 to seal the proximal ends of the longitudinal lumens 5242, 5244. The plug 5250 may be formed of any suitable material similar to or different from the material of waveguide 5230 and may be welded, brazed, adhered, molded, compression-fitted (e.g., the plug 5250 is formed of an elastic material), threaded, or otherwise secured within the proximal aperture 5236. The plug 5250 occupies only a portion of the proximal aperture 5236 such that the proximal body of waveguide 5230 (not shown, see proximal body 232) Figure 4A The proximal body and the distal body 5234 are connected and fixed to each other by an internal thread or other suitable engagement in the proximal hole 5236 so that ultrasonic energy can be transmitted along them.

[0078] While several aspects and features of this disclosure have been detailed above and illustrated in the accompanying drawings, it is not intended to limit the disclosure thereto, but rather to have the broad scope permitted by the art and the understanding of the specification. Therefore, the above description and drawings should not be construed as limiting, but merely as examples of particular configurations. Other modifications within the scope and spirit of the appended claims will be contemplated by those skilled in the art.
