The irrigation and / or aspiration lines are typically , has been connected to the outside of the ultrasonic handpiece connected to the sleeve. The sleeve and / or The cutting accessory is disposable. As a result, the sleeve and / or cutting accessory is only temporarily attached to the ultrasonic handpiece. The attachment of additional elements such as an irrigation line and / or a suction line to the outside of the handpiece may increase the size, profile, and / or overall bulk of the ultrasonic handpiece. This may obstruct the view of the medical professional and / or distract the medical professional during the operation of the medical instrument during the medical procedure. The placement of the irrigation line and / or suction line with respect to the ultrasonic handpiece may similarly affect the usability of the ultrasonic handpiece and hinder the ability of the medical professional operating the ultrasonic handpiece.

The drive signal is applied to the piezoelectric crystals 46. At any given moment, the same drive signal is applied to each of the plurality of piezoelectric crystals 46. By applying the drive signal, the plurality of piezoelectric crystals 46 expand and contract simultaneously and periodically. The stack of piezoelectric crystals 46 typically has a length of from 1 cm to 5 cm. The distance of movement, i.e., the amplitude, in one expansion and contraction cycle of the piezoelectric crystal 46 is between 1 μm and 10 μm. The horn 40 is configured to amplify this movement.

[0036] The distal housing portion 16 of the ultrasonic handpiece 12 further includes a flex circuit 62 formed within the distal housing portion 16. The flex circuit 62 is composed of a conductive material configured to transmit electrical signals between the distal and proximal regions of the flex circuit 62. The flex circuit 62 includes a mounting portion 64 disposed in the proximal region of the flex circuit 62. The mounting portion 64 is configured to couple to a processor disposed within the ultrasonic handpiece 12. The processor is configured to communicate with the control console 13. Alternatively, the mounting portion 64 of the flex circuit 62 may be configured to couple to a wire, cable, or similar conductor that is coupled to the control console 13 via the cable 30. The processor or wire is configured to transmit electrical signals that control the power supply, irrigation, and / or aspiration functions of the ultrasonic handpiece 12 between the flex circuit 62 and the control console 13. The flex circuit 62 also includes a transceiver 66 located in the distal region of the flex circuit 62. As described below, the position of the transceiver 66 within the ultrasonic handpiece 12 should be tightly controlled to ensure that the corresponding coil of the sleeve 18 is always read when the sleeve 18 is coupled to the ultrasonic handpiece 12. 12. In addition, the aforementioned lumen 59, which is at least partially disposed within the ultrasonic handpiece 12, defines

[0037] The defined tube 58 is also shown in FIG. 5. The tube 58 is at least partially disposed within the distal housing portion 16 and the proximal housing portion 14. Further, the tube 5 8 is provided with a connection feature 56 such as a hose barb or similar fitting configured to provide a friction fit. The connection feature 56 is disposed at the proximal end of the tube 58 and is configured to connect the tube 58 to the irrigation line 29 extending from the control console 13 to the ultrasonic surgical handpiece assembly 10. The irrigation line 29 extending from the console 13 is connected to the ultrasonic handpiece 12 via the hose barb 56 to facilitate the flow of irrigation fluid through the tube 58 within the ultrasonic handpiece 12 and toward the sleeve 18 and / or the ultrasonic chip 20. In the foregoing configuration, the irrigation fluid flows through the ultrasonic handpiece 12 from the proximal end of the ultrasonic handpiece 12 to the distal end of the ultrasonic handpiece 12 and / or the sleeve 18, thereby eliminating the need for a bulky irrigation line connected to the side of the ultrasonic handpiece 12 or the sleeve 1 8. This configuration is made possible by providing a path for the irrigation line through the handpiece 12. Thus, neither the sleeve nor the ultrasonic handpiece has an irrigation connection portion along its side. Alternatively, in other configurations, the tube 58 may be connected to the suction line 2 7 via the connection feature 56. In this case, a vacuum draw through the tube 58 can be performed using the suction line 27.

[0038] Referring to FIG. 6, an exploded view of the distal housing portion 16 of the ultrasonic handpiece 12 is shown. The distal housing portion 16 comprises a first half 68 and a second half 70 configured to be joined together to form a part of the distal housing portion 16. The first half 68 and the second half 70 are each injection molded from a plastic for injection molding or a similar lightweight durable material. Furthermore, the first half 68 and the second half 70 are each molded such that when the first half 68 and the second half 70 are joined together, a groove 74 or a recess (forming a passageway) is formed in the distal housing portion 16. Also considered is that the groove 74 may be formed in only one of the first half 68 or the second half 70. The groove 74 is configured to receive at least a part of the flex circuit 62. The groove 74 further comprises a cavity 72 located at the distal end of the groove 74. The cavity 72 is configured to receive the transceiver 66 located in the distal region of the flex circuit 62. The cavity 72 has dimensions larger than the groove 74 to accommodate the size of the transceiver 66 relative to the flex circuit 62. The cavity 72 and the groove 74 are adjacent to each other. The cavity 72 is shown to be located near the distal end of the distal housing portion 16. However, it is also considered that the first and second halves 68, 70 may be configured such that the flex circuit 62 and the transceiver 66 are arranged in alternative positions. For example, the cavity 72 may be arranged near the proximal end of the distal housing portion 16. In yet other configurations, the first and second halves 68, 70 are not arranged along a vertical axis, and the first half 68 is not arranged along a vertical axis, and the first half 68 is above the second half 70. above the second half 70. above the second half 70. It may be configured to be divided along a horizontal axis so as to be located above the semi-body 70. This In this configuration, the groove 74 and the cavity 72 are formed within the contact surface (interface) of the first and second semi-bodies 68, 70 and the flex circuit 62 and the transceiver 66 may be disposed on the right or left side of the distal housing portion 16.

[0039] The position of the cavity 72 should be precisely controlled to enable communication between the transceiver 66 and the RFID tag 88 of the sleeve 18 (see FIG. 8). For example, the cavity 72 is arranged within the distal housing portion 16 so as to shorten the distance between the transceiver 66 and the corresponding RFID tag 88 of the sleeve 18 when the sleeve 18 and the ultrasonic handpiece 12 are connected to each other. The cavity 72 is arranged so as to ensure that the plane defined by the transceiver 66 is positioned substantially parallel to the plane defined by the RFID tag 88 of the sleeve 18.

[0040] As described above, the flex circuit 62 includes a transceiver 66 located at the distal end of the flex circuit 62. The transceiver 66 includes an antenna. This antenna is configured to transmit a signal to the corresponding RFID tag associated with the sleeve 18 and receive a response. The flex circuit 62 is at least partially disposed within the groove 74 of the distal housing portion 16 when the first and second semi-bodies 68, 70 are connected to each other. The flex circuit 62 is generally formed as a thin strip (thin strip) of a ribbon having internal copper elements such as wiring. With this configuration and structure, the flex circuit 62 is fragile or easily damaged, which makes it difficult to cooperate with the flexible circuit or to be mounted into the distal housing portion 16 of the flexible circuit. For example, it is necessary to handle the flexible circuit so as not to crush or break it. Also, it is desirable to pay attention to avoiding operations such that multiple layers of the flexible circuit 62 peel off. Therefore, the groove 74 formed in the distal housing portion 16 should be arranged to avoid sharp bending or twisting and to extend smoothly along its length. During the assembly process, prior to the first half 68 and the second half 70 of the distal housing portion 16 being connected to each other, the flexible circuit 62 is preferably arranged in the groove 74 and the transceiver 66 is arranged in the cavity 72, whereby the position of the transceiver 66 will be fixed within the distal housing portion 16. It should be recognized that the transceiver does not necessarily need to be arranged at the distal end of the flexible circuit. If the first half 68 and the second half 70 of the distal housing portion 16 are mechanically fitted to each other such that the position of the transceiver 66 is fixed, the distal housing portion 16 is overmolded (outer coated) with an autoclave - processable plastic to form the finished structure of the distal housing portion 16 shown in FIG. 5. By overmolding the flexible circuit 62 and the transceiver 66 in the distal housing portion 16 of the ultrasonic handpiece 12 with an autoclave - processable plastic, the flexible circuit 62 is protected from heat damage that occurs during the autoclave process used to sterilize the ultrasonic handpiece 12. Further, it is not a plastic having a melting point of less than 150°C.

[0041] ​By using a plastic capable of autoclave processing, the distal housing portion 16 can be repeatedly processed by autoclave sterilization without significant degradation. Thus, prior to overmolding with a plastic capable of autoclave processing, by placing the flexible circuit 62 within the grooves 74 of the first and second halves 68, 70 the flexible circuit 62 is sufficiently insulated from the thermal energy of the molten autoclave-processable plastic by the first and second halves 68, 7 0, such that the flexible circuit 62 will not delaminate during the overmolding process. The results of the foregoing process are shown in the apparatus of FIGS. 5 and 8. The autoclave-processable plastic is to be understood as a polymer having a melting point above 150° C. The process of placing the flexible circuit 62 is described with respect to the two halves 68 of the distal housing portion 16, 70, but it should be recognized that a similar process may be used with suitable medical device housings where it is important to accurately position a portion of the flexible circuit 62, for example, medical device housings that do not comprise two separate halves. Although not shown, the ultrasonic handpiece 12 also comprises a memory. The memory contains data that describes the characteristics of the ultrasonic handpiece 12. The memory may take the form of an EPROM, E EPROM, or may be included in the aforementioned RFID tag 88. In addition to containing readable data, the memory also contains manufacturing

It should be recognized that the process of placing the flexible circuit 62 is described with respect to the two halves 68, 70 of the distal housing portion 16, but a similar process may be used with suitable medical device housings where it is important to accurately position a portion of the flexible circuit 62, for example, medical device housings that do not comprise two separate halves.

[0043] Although not shown, the ultrasonic handpiece 12 also includes a memory. The memory contains data that describes the characteristics of the ultrasonic handpiece 12. The memory may be in the form of an EPROM, E EPROM, or may be included in the aforementioned RFID tag 88. In addition to containing readable data, the memory also contains manufacturing data of the ultrasonic handpiece 12. It is possible to store the data written to the memory after fabrication. Reading data from the memory and writing data to the memory are facilitated by auxiliary components (not shown) attached to the hand piece. These auxiliary components include one or more of the following elements, namely, conductors, exposed contacts / contact pins, coils / antennas, or insulated circuits (isolated circuits).

[0044] Referring to FIGS. 7-9, an exemplary configuration of the joint portion between the distal housing portion 16 and the sleeve 18 and / or the ultrasonic chip 20 is shown. FIG. 7 shows a front view of an exemplary configuration of the distal end of the aforementioned distal housing portion 16. The distal end of the distal housing portion 16 may also be referred to as the distal end of the ultrasonic handpiece 12. The distal end of the ultrasonic handpiece 12 has an attachment region 69 configured to function as a joint portion between the ultrasonic handpiece 12 and the sleeve 18 and the ultrasonic chip 20. The attachment region 69 has a recess 71 defined by a proximal surface 78 and a distal surface 79. The proximal surface 78 and the distal surface 79 are connected to each other by a plurality of walls 77 extending perpendicular to the proximal surface 78 and the distal surface 79. The proximal surface 78 has an opening 73. The opening 73 has a connecting feature 75 around it (see FIG. 9). The connecting feature 75 is composed of tabs, lips, or similar snap - fit connection mechanisms.

[0045] The distal end of the horn 40 is configured to partially penetrate the opening 73 defined in the proximal surface 78. At least a part of the horn 40 and the threaded coupler 38 are disposed within the recess 71 at the distal end of the ultrasonic handpiece 12. A second conduit 42 passing through the horn 40​ is also open to the recess 71.

[0046] The proximal surface 78 further includes an irrigation coupler 76 located at the distal end of a tube 58 that defines a lumen 59 passing through the ultrasonic handpiece 12. The irrigation coupler 76 is configured to fluidly communicate with the lumen 59 disposed within the ultrasonic handpiece 12 for supplying irrigation fluid to the sleeve 18. The irrigation coupler 76 is composed of a fixture, a hose barb, or a similar connecting member for connecting the distal end of the tube 58 to the corresponding irrigation line 29 of the sleeve 18. The irrigation coupler 76 functions as an inlet or outlet for transferring materials (objects) and / or fluids between the ultrasonic handpiece 12 and the sleeve 18. The irrigation coupler 76 is configured to fluidly communicate with the lumen 59 disposed within the ultrasonic handpiece 12 for supplying irrigation fluid to the sleeve 18.

The irrigation coupler 76 functions as an inlet or outlet for transferring materials (objects) and / or fluids between the ultrasonic handpiece 12 and the sleeve 18.

[0047] Referring to FIG. 8, a partial exploded view of the joint between the distal end of the ultrasonic handpiece 12 and the sleeve 18 is shown. The sleeve 18 includes a hub 21 located at the proximal end of the sleeve 18 and a sleeve body 19 extending distally from the hub 21. The sleeve 18 includes a lumen 98 defined by the hub 21 and the sleeve body 19. The lumen 98 extends along the length of the sleeve 18 and is configured to surround at least a portion of the ultrasonic chip 20 when the ultrasonic chip 20 is connected to the ultrasonic handpiece 12. The sleeve 18 includes a lumen 98 defined by the hub 21 and the sleeve body 19. The lumen 98 extends along the length of the sleeve 18 and is configured to surround at least a portion of the ultrasonic chip 20 when the ultrasonic chip 20 is connected to the ultrasonic handpiece 12. The sleeve 18 includes a lumen 98 defined by the hub 21 and the sleeve body 19.

The sleeve 18 includes a lumen 98 defined by the hub 21 and the sleeve body 19. The lumen 98 extends along the length of the sleeve 18 and is configured to surround at least a portion of the ultrasonic chip 20 when the ultrasonic chip 20 is connected to the ultrasonic handpiece 12. The hub 21 includes a protrusion 80. The protrusion 80 extends proximally from the distal surface 84 of the hub 21 and terminates at the proximal surface 82. The proximal surface 82 of the protrusion 80 is oriented to be substantially parallel to the distal surface 84. The shape of the protrusion 80 is defined by a plurality of outer peripheral surfaces 81 or wall members extending between the distal surface 84 and the proximal surface 82. The outer peripheral surfaces 81 or wall members define the shape of the protrusion 80. is configured to define the outer periphery thereof. The outer peripheral surface 81 is oriented substantially perpendicular to the proximal surface 82 and / or the distal surface 84. The shape of the protrusion 80 is positioned so as to fit tightly within the recess 71, whereby it is to be recognized that the outer peripheral surface 81 of the protrusion 80 engages the wall 77 of the recess 71.

[0048] However, although not shown, the outer peripheral surface 81 of the protrusion 80 may be oriented at an angle other than 90° with respect to the proximal surface 82 and / or the distal surface 84 to form a tapered protrusion 80. This is further considered. For example, the area defined by the outer peripheral surface 81 of the protrusion 80 close to the distal surface 84 may be larger than the area of the proximal surface 82.

[0049] The hub 21 further includes a fixture 94 extending from the proximal surface 82 of the protrusion 80. The fixture 94 is configured to connect to a corresponding fixture 76 of the ultrasonic handpiece 12.

Specifically, the fixture 76 is dimensioned to fit within the fixture 94 when the sleeve 18 is connected to the ultrasonic handpiece 12. For example, the perfusion fluid from the ultrasonic handpiece 12 flows into the sleeve 18 by the connection of the fixture 94 to the fixture 76. This eliminates the need to connect the sleeve to a perfusion line separate from the ultrasonic handpiece 12, for example, a perfusion line connected to the side of the sleeve 18. Alternatively, a vacuum may be applied to the ultrasonic handpiece 12 configured to aspirate material (objects) from the sleeve 18 through the fixtures 94, 76 connected by an alternative configuration. ​​​​​​​​​​​

[0050] The sleeve 18 further includes a conduit 96 formed within the sleeve body 19 so as to extend adjacent to the lumen 98 of the sleeve 18. The fixture 94 is connected to the proximal end of the conduit 96. The conduit 96 is configured to direct perfusion fluid through the sleeve 18 separately from the lumen 98 of the sleeve 18. The path of the conduit 96 through the sleeve 18 may be formed in various ways. The hub 21 further includes a cavity 86 formed in the projection 80. The cavity 86 has an opening in the proximal face 82 of the projection 80. The cavity 86 is configured to at least partially surround a tag 88, an antenna, a transceiver, or a similar wireless communication device.

The axis is adjusted so as to be approximately parallel to the plane on which the axis is set.

[0052] The RFID tag 88 in the sleeve 18 should be understood as a chip memory. The RFID tag 20 and sleeve 18 are typically packaged together in a kit. The data contained in the log 88 is used to control the operation of the ultrasound tip 20. The coil 89 embedded in the probe 18 is connected to the memory unit of the RFID tag 88.

Pin 89 is formed from a plastic or alloy material and is frictionally fitted within the opening of cavity 86 to fix RFID tag 88 within cavity 86 and protect RFID tag 88 from damage Alternatively, pin 89 may be configured to include a seal such as an elastomeric O-ring In yet another configuration, pin 89 may be configured to include an epoxy resin, adhesive (glue), sealant, or similar compound configured to fix tag 88 within cavity 86 and protect the tag from damage. Furthermore, it is contemplated that RFID tag 88 may be injection molded or heat crimped within sleeve 18. R FID may be other forms of tags.

[0054] Protrusion 80 is configured to have a shape complementary to the shape defined by recess 71 at the distal end of ultrasonic handpiece 12 such that sleeve 18 is coupled to ultrasonic handpiece 12 ​​​configured to be disposed within the recess 71 when. Further, the recess 71 and the protrusion 80 each have a shape configured such that the sleeve 18 is aligned straight with respect to the ultrasonic handpiece 12 and prevents rotational movement of the sleeve 18 with respect to the ultrasonic handpiece 12. For example, as shown in FIG. 8, the recess 71 of the ultrasonic handpiece 12 includes a plurality of walls 77 defining the periphery of the recess 71. An exemplary configuration of the recess 71 shown in FIGS. 7 and 8 is such that the walls 77A, 77B, 77C, 77D define a doghouse-like shape, and two opposing walls 77A, 77B are substantially parallel to each other. The two opposing walls 7 7A, 77B are connected to each other by a third wall 77C that is substantially perpendicular to these walls 77A, 77B. A fourth wall 77D on the side opposite the third wall 77C also connects the two opposing walls 77 A, 77B to each other, but this fourth wall 77D has a substantially arched shape. On the other hand, the plurality of outer peripheral surfaces 81A, 81B, 81C, 81D defining the outer periphery of the protrusion 80 are configured to define a doghouse-like shape corresponding to the shape of the recess 71. Although not shown, the walls 77A, 77B, 77C, 77D of the recess 71 and the corresponding outer peripheral surfaces 81A, 81B, 81C, 81D of the protrusion 80 may be configured to define alternative shapes. For example, the walls 77 and the outer peripheral surfaces 81 may define a rectangular, star-shaped, elliptical, triangular or other similar shape. The illustrated protrusion 80 and recess 71 have complementary shapes, but it is further contemplated that they may have slightly different shapes as long as the protrusion 80 is disposed within the recess 71. For example, the protrusion 80 of the sleeve 18 may be chamfered between the outer peripheral surfaces 81C and 81A and / or 81B to provide further clearance for the protrusion. It may be configured to provide such an outer peripheral surface 81, and even such a sleeve 18 is similarly inserted into the ultrasonic handpiece 12 and functions.

[0055] The shapes of the protrusion 80 and the recess 71 are such that a tag 88 disposed within the cavity 86 of the hub 21 is oriented with respect to a transceiver 66 disposed within the distal housing portion 16 of the ultrasonic handpiece 12. It is further configured to orient the tag 88 with respect to the transceiver 66 by utilizing the shapes of the protrusion 80 and the recess 71. By orienting the tag 88 with respect to the transceiver 66, the communication between the tag 88 and the transceiver 66 can be improved to establish highly reliable communication. For example, as shown in FIG. 9, the tag 88 and the transceiver 66 are positioned (so as to overlap) such that they are at least partially axially overlapped when the sleeve 18 is connected to the ultrasonic handpiece 12. Furthermore, the cavity 86 of the hub 21 and the cavity 72 of the distal housing portion 16 of the ultrasonic handpiece 12 are oriented such that the first major axis of the tag 88 and the second major axis of the transceiver 66 are substantially parallel to each other. The protrusion 80 and the distal housing portion 16 are further configured to shorten the distance between the cavity 86 of the hub 21 and the cavity 72 of the distal housing portion 16 and further improve the communication between the tag 88 and the transceiver 66. The hub 21 further includes a plurality of retaining fingers 90 extending distally from the proximal surface 82 of the protrusion 80. The plurality of retaining fingers 90 are spaced apart from each other around the lumen 98 defined in the proximal surface 82. The plurality of retaining fingers 90 are configured to engage with the connecting feature 75 around the opening 73 of the proximal surface 78 of the recess 71 of the ultrasonic handpiece 12.

[0056] It further includes formed tabs 92, ridges, or protrusions. Each of the plurality of retaining fingers 90 Each of the respective tabs 92 engages with the connecting feature 75 of the recess 71 to form a snap-fit and / or friction-fit portion that removably connects the sleeve 18 to the ultrasonic handpiece 12. The plurality of retaining fingers 92 are composed of a highly compliant material such as silicone rubber (highly flexible material), or a metal material such as a leaf spring. Although not shown, it is also contemplated that the sleeve 18 may be connected to the ultrasonic handpiece 12 in several other ways. For example, the hub 21 may be configured without the retaining fingers 90, and the infusion coupler 76 of the ultrasonic handpiece 12 may be fitted into the infusion fixture 94 of the sleeve 18 to form the main retaining mechanism. In yet another form, the protrusion 80 may be composed of a compliant material and may include an RFID tag 88 disposed within a slit of the compliant material and may be press-fitted into the cavity 71 as well. Referring to FIG. 9, a cross-sectional view of an exemplary configuration of the joint portion between the distal housing portion 16 of the ultrasonic handpiece 12, the sleeve 18 and the ultrasonic chip 20 is shown. As shown in FIG. 9, when the sleeve 18 is connected to the ultrasonic handpiece 12, the distal surface 79 of the distal housing portion 16 abuts (adjacent) against the distal surface 84 of the protrusion 80. This promotes the formation of a stable connection of the sleeve 18 to the ultrasonic handpiece 12. Similarly, when the protrusion 80 is disposed within the recess 71 to connect the sleeve 18 to the ultrasonic handpiece 12 the proximal surface 78 of the distal housing portion 16 abuts (adjacent) against the proximal surface 82 of the protrusion 80 .

That's okay.
